The lens and camera interface
The lens and camera interface was a component used to connect the lens and the camera. Suzhou Ouka optical instrument factory specialized in the production and development of a camera interface, this interface can be connected to different brands and models of lenses, so that the camera can be used normally. There are many types of industrial camera cable ports: - **USB port **: It is a commonly used port for digital cameras. It can directly output digital image signals. USB was the full name of Universal serial bus. The interface was 4-pin, including 2 power cables and 2 signal cables. There were different versions of USB. The early USB2.0 interface was convenient and widely used, but the transmission rate was slow (480Mbit/s), the communication distance was short (5m), and the band width was mostly used for image transmission (80%). The transmission required the CPU to participate in management and consumed a lot of resources, and the interface was unstable. USB3.0 added two sets of data lines on the basis of USB2.0, which were backward compatible. The transmission speed was increased to 4.8Gbit/s, and the communication distance was extended to 10m. However, the transmission distance was still relatively short. USB interface cameras were easy to use and had a wide range of ports. They were widely used in microscopes, scientific research experiments, portable equipment, and other industries. At present, USB Type Micro-B ports were the mainstream on industrial interface cameras. In the future, USB Type C ports might be popularized. - ** IMEE1394 (Firewire Interface)**: It is a high-speed serial bus. It supports hot swapping, real-time data transmission, and uses a bus structure. It is widely used in the industrial field. It has good protocol and coding methods, and the transmission speed is stable. The 1394a's maximum transmission speed was 400mps, and the 1394b's maximum transmission speed was 800mps (3.2mps was relatively rare). Its interface was divided into 4-core and 6-core. The 4-core contained two pairs of data cables, and the 6-core had a set of power cables in addition to the data cable. This interface did not require a controller and could be used for peer-to-peer transmission. The 1394a's maximum transmission distance was 4.5 meters, and the 1394b's transmission distance was usually 10 meters (100 meters, 100 Mbit/s, when the data rate was reduced). However, the interface's penetration rate was low and it had been slowly eliminated by the market. - **Camerlink interface **: A digital image signal communication interface protocol introduced by the Aia Association. It is a serial communication protocol that uses the LVVS interface standard. It was developed from the Channel Link technology, adding the transmission control signal and defined the relevant transmission standards. The protocol used the MDR - 26-pin connection or the SAR- 26-pin connection, which had high speed (up to 6400Mbps), strong anti-interference ability, and low power consumption. However, it required a separate CameraLink interface, which was not portable, expensive, and rarely used in practical applications. - ** Gige Giga-bit ether interface **: created and promoted by Aia. It is a camera interface standard developed based on the Giga-bit ether communication protocol. It is suitable for industrial imaging applications. It can transmit uncompressed video signals over the network and can use low-cost cables to transmit images over long distances. In addition, in the field of machine vision, other data transmission ports were also developed: - **CoaXPress (CXP) interface **: launched in 2008, supports high-speed imaging applications, uses 75 Omega coax cable, supports data transmission speed of up to 6.25Gbit/s per channel, and can increase the transmission rate of multiple channels. Each cable can provide up to 13W of power. It requires the "device" and "host" to support the GenICam camera programming interface. However, the cost of installing multi-channel cable components and frame clips on a single-channel coax cable increases rapidly. - **CameraLink interface **: In 2000, it was launched by Aia Association and gradually upgraded.（2.04Gbit/s）、Medium (5.44Gbit/s) and Deca/Extended (6.8Gbit/s). Base uses an ADC- 26 pin, medium/full requires a second cable to double the capacity, Deca/Extended can transmit up to 6.8Gbit/s data, and like the CXP interface, it requires an image acquisition card that is compatible with the CameralLink power supply (PoQL) standard for power supply. It lacks error correction or resend functions. The cable setup was expensive and troublesome. - **GigE Vision standard interface **: It is managed by the Aia Association and allows the use of existing low-cost ether cables, connections, switches, and other components. Copper cables can transmit image data up to 100 meters away, and more data can be transmitted through the switch and optical fiber adapters. It has the potential to create different network topologies. Each camera can be placed on the network independently through an IP address. It can be viewed, controlled, and monitored from any PC on the network. However, the maximum 115mb/s has limitations for certain applications. However, NBUSE-T technology could increase the band width within its framework. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Industrial camera communication interface
The communication interface of industrial cameras mainly has the following types: 1. **USB port **: - ** USB 1.0 **: released in 1996, transmission speed of 1.5Bit/s. - **USB1.1**: released in 1998, transmission speed of 12 Mbit/s, suitable for USB mouse, keyboard, home scanner, etc. - **USB2.0**: released in 2000, transmission speed of 480 Mbit/s, communication distance of 5m, 80% of the band width used for image transmission. The early USB 2.0 interface was easy to connect. Almost all computers had a USB interface, so there was no need for an acquisition card. However, the transmission rate was slow, and the transmission process required the CPU to participate in the management. It took up and consumed a lot of resources, and the interface was unstable. - **USB3.0**: released in 2008, transmission speed of 4.8Gbit/s, communication distance of 10m, 80% of the band width used for image transmission. USB3.0 added two sets of data cables on the basis of USB2.0, which were backward compatible and solved the problem of slow transmission speed. USB cameras were easy to use and had a wide range of ports. They were currently widely used in microscopes, scientific research experiments, portable equipment, and other industries. The USB Type Micro-B interface was still mainstream in industrial cameras. With the maturity of USB Type C technology, USB Type C interface might be popularized in future USB cameras. 2. ** IMEE1394 (Firewire Interface)**: The IMEE1394 bus is a high-speed serial bus, also known as Firewire. It supports hot swapping, real-time data transmission, and uses a bus structure and plug and play. It is used to connect digital products to computers and other machines. It is widely used in the industrial field. Its protocol and coding method were good, and the transmission speed was stable. The maximum transmission speed of 1394a was 400Mbit/s, and the maximum transmission speed of 1394b was 800Mbit/s (3.2Gbit was relatively rare). The interface had a low penetration rate and was monopolized by Apple in the early days. This interface was usually not included in the computer and required an additional acquisition card. The 1394 interface was divided into 4-core and 6-core. There were two pairs of data cables in the 4-core, and the 6-core also included a set of power cables to supply power to external devices. The 1394 interface does not require a controller and can achieve peer-to-peer transmission. The maximum transmission distance of 1394a is 4.5 meters, and the transmission distance of 1394b is usually 10 meters. It can be extended to 100 meters (100 Mbit/s) when the data rate is reduced. The transmission distance can be further improved by using relay equipment, but it has been slowly eliminated by the market. 3. **Camerlink interface **: A digital image signal communication interface protocol introduced by the Aia Association. It is a serial communication protocol that uses the LVVS interface standard (differential technology: LVVS (low voltage differential signal)). It has the characteristics of high speed, strong anti-interference ability, and low power consumption. It was developed from the Channel Link technology, adding some transmission control signals on the basis of which the relevant transmission standards were defined. The protocol uses an ADC- 26 pin or an SSR- 26 pin, and the band width can reach 6400 Mbit/s. However, it requires a separate CameraLink interface, which is not portable, resulting in high cost and less practical applications. 4. **Gige Giga-bit ether interface **: It was created and promoted by the Aia(Automatde Imaging Association). It was a camera interface standard developed based on the Giga-bit ether communication protocol. 5. **CoaXPress interface **:(The reference does not mention the interface features in detail, only listing it as an industrial camera interface type). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Nikon single-lens reflex camera lens interface
The lens mount of a Nikon single-lens reflex camera was an F-mount. From the early film DSLR to the recent digital DSLR, they all used F-mount. In terms of F-mount lenses, due to the different mechanical/electronic transmission methods of aperture adjustment, aperture information transmission, focal length information transmission, and autofocus, there were many types of single-lens reflex lenses. For example, manual non-CPU lenses included STAR lenses, AI lenses, AIS lenses, etc. According to the type of aperture adjustment, there were D-type lenses with manual aperture rings, G-type lenses without manual aperture rings, E-type lenses with electromagnetic apertures, etc. The F-mount lens was divided into two types: the FX-mount lens (suitable for all Nikon single-lens reflex cameras, similar to Canon's EF-mount lens) and the DX-mount lens (suitable for Nikon APS-C format cameras, similar to Canon's EF-mount lens). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to choose the camera lens interface
Choosing a camera lens interface required consideration of the following aspects: ###1. Type of camera mount 1. ** Understand the brand and model of the camera ** - Different camera brands had their own typical mounts. For example, Canon had the EF, ef-s, ef-m, and rf-mount; Nikon had the f-mount and z-mount; Sony had the a-mount and e-mount; Pantheon had the M4/3 and l-mount; Pentax had the k-mount; Fuji had the x-mount and g-mount. If you already have a camera body, you must choose a lens mount that matches the camera body mount. Otherwise, the lens cannot be installed on the camera body. 2. ** Consider compatibility with future upgrades ** - For some users who might upgrade their bodies in the future, they should pay attention to the development trend of the camera brand mount. For example, when Canon upgraded from a traditional mount to an all-electronic mount, choosing a forward-looking mount type lens interface might reduce the risk of the lens not being usable in the future. ###2. Use of the lens 1. ** Requirement for photography type ** - If you were mainly doing landscape photography, you might need to consider some types of lens with large apertures and high resolution to meet the requirements of shooting in different lighting conditions and the details of the picture. For example, on a full-frame camera, a large-caliber bayonet might be more suitable for a high-end wide-angle lens to reduce aberrations and dark angles. - If it was portrait photography, it might be necessary to consider a lens interface that could support fast autofocus to ensure fast and accurate focus when shooting people, such as some bayonet and lens combinations with advanced focusing technology. - For video shooting, like Canon C300 III with Canon lens, the stability of the lens interface during zooming and the video focusing performance had to be considered to ensure that there would be no problems such as out of focus during video shooting. 2. ** Special shooting requirements ** - If macro photography was needed, a special macro lens interface might be needed. This interface could ensure the accuracy and optical performance of the lens when focusing at close range. ###3. Brand of lens and compatibility 1. ** Original factory lens and sub-factory lens ** - The original lens generally had good compatibility with the camera body mount, and it performed best in terms of function implementation (such as autofocus, aperture control, etc.). For example, Nikon's F-mount lens could fully utilize the communication function between the Nikon body and the lens on a Nikon DSLR camera. - Although the sub-factory lens was cost-effective, one had to pay attention to the compatibility of the bayonet. Some sub-factory lenses may need to be reverse-engineering to fit the camera mount, and there may be compatibility issues, such as inaccurate focus on some mount cameras or the need for a hardware upgrade to be used normally. For example, sub-factory lens manufacturers such as Tenglong, Sima, and Tuli would release different versions of lenses for different bayonet mounts, and the time to market for different bayonet mounts might be different. The performance of the same model lens on different bayonet cameras might also be different. ###4. Budgets 1. ** Impact of mount on lens price ** - Some bayonet lenses with advanced technology or exclusive agreements were relatively more expensive. For example, due to the complexity of the agreement, Nikon's lens development cost may be transferred to the price, while Canon's radio frequency bayonet is more difficult to reverse, which may also lead to the high price of related lenses. Relatively speaking, some sub-factory lenses might have an advantage in price under the same bayonet, but they had to weigh the relationship between quality, compatibility, and budget. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The interface between the lens and the camera is divided
There were three types of interface between the lens and the camera, namely F, C, and CS. There were also M42, Lycra, Hassel, and AK. The F-type interface was a universal interface, generally suitable for lenses with a focal length greater than 25mm; when the focal length of the objective lens was less than 25mm, the C-type or C-type interface was used because the size of the objective lens was not large. The difference between the C interface and the CS interface was that the distance between the contact surface of the lens and the camera to the focal plane of the lens (the position where the camera's CCD-sensor should be) was different. The distance between the C-type interface was 17.526mm, and the distance between the CS interface was 12.5mm. The C-type lens and the C-type camera, the CS lens and the CS camera could be used together. A 5mm C/CS transition ring between the C-type lens and the CS camera could be used together, but the CS lens and the C-type camera could not be used together. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Industrial camera installation interface type
The common installation interface types of industrial cameras include C interface, CS interface, F interface, V interface, T2 interface, M42 interface, M50 interface, etc. The C-Mount lens was the most commonly used interface type in the field of machine vision. The rear port was a 25mm diameter screw port interface, and the image surface size was 2/3 / 1/2 inches. It had the characteristics of high-definition coating, glass lens, and metal shell. The aperture had no gear change, and there were aperture value and focus value labels. The aperture could be opened and closed. In addition, different interface types have no direct relationship with the performance and quality of industrial lenses. If necessary, you can also find the interface between various commonly used ports. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The pitch of the industrial camera body interface ring
If it was a C-interface industrial camera body interface ring, the thread specifications were 1 inch in diameter, the thread was 32 teeth/inch, and the pitch was 25.4/32. Generally, the transition ring could be processed according to 25mm ×0.75mm. As for other types of interface, the reference did not mention any information about the pitch of the interface ring, so it was impossible to answer accurately. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Machine vision industrial camera and lens selection
Machine vision industrial cameras and lens selection needs to consider the following aspects: ** I. Selection of industrial cameras ** 1. ** resolution ** - First of all, the accuracy requirements and field of view must be clearly defined to calculate the required camera resolution. For example, if the detection accuracy is 0.01mm and the field of view is 21mm x 16mm, then the camera resolution should reach (21/0.01) X (16/0.01) about 3 million pixels. To obtain high-quality images and high-precision detection, a camera with a higher resolution such as 5 million resolution could be considered. 2. ** Type of sensor ** - It was mainly divided into two categories, namely, CCD-based and CMOS-based. At present, CMOS-based had gradually become mainstream. When choosing a LCD sensor, if you need to capture dynamic images, a global shutter LCD sensor is more suitable; for static image capture, a rolling shutter LCD sensor is a better choice. 3. ** Interface Selection ** - The distance and size of the data transmission had to be considered. The USB 3.0 interface is fast but the transmission distance is limited.(The theoretical transmission speed limit is about 500mb/s, and it is not recommended to use it over a distance of more than 5 meters);GigE (GigE) interface can be used over long distances.(Up to 100 meters) High-speed data transmission (up to 1Gbit/s), suitable for industrial scenarios where cameras are deployed over a large area and require high data transmission speed and stability, such as large-scale factory automated production line monitoring. The Camera Link interface is a high-speed serial interface specially designed for industrial cameras. The data transmission rate is very high. It is used in professional industrial testing fields that require extremely high speed and accuracy, such as the manufacturing process of semiconductor chips. 4. ** Color Selection ** - If the detection target involves color recognition, a color camera should be used; if color recognition is not needed, a black-and-white camera is more cost-effective. Color cameras could record the three basic colors of red, green, and blue to form a color image. Different color cameras had different color depths (usually measured in bits). The higher the color depth, the higher the color reproduction of the image. For example, an 8 - bit color camera could record 256 (2 ^8) color levels, and a 12 - bit camera could record 4096 (2 ^12) color levels. Black-and-white cameras only recorded light intensity information and output black-and-white images. They had advantages in scenes sensitive to light contrast (such as detecting object contours and edges), and the data processing capacity was relatively small, so the processing speed might be faster. 5. ** Framerate ** - The frame rate refers to the number of images captured by the camera in a unit of time (usually one second). Shooting and analyzing high-speed moving objects (such as car crash test, high-speed production line product inspection, etc.), a high frame rate camera (such as 30fps or above) is needed to clearly capture the moment of object movement, analyze the movement trajectory and speed change, etc. For relatively static or slow-moving object monitoring scenes (such as indoor warehouse monitoring, office monitoring, etc.), a lower frame rate camera (such as 10 - 15fps) can meet the needs, and can also reduce data storage and transmission bandwith requirements. 6. ** Pieces ** - Pieces were the basic unit of imaging for industrial cameras. The greater the number, the richer the image details could be recorded. When detecting the surface defects of small parts, high-resolution cameras could capture details such as scratches and cracks more clearly. At the same time, under the same conditions, the higher the resolution, the larger the size of the image. This was very important for scenes that required large-sized images for post-processing or overall observation. 7. ** Target ** - The target surface of the camera referred to the size of the image sensor's sensitive area, usually expressed in inches. The larger the target, the wider the field of view, suitable for shooting larger objects or wider scenes (such as monitoring large warehouses); the smaller the target, the narrower the field of view, suitable for shooting small objects or close-up shots of local details (such as microscopic inspection in electronic chip manufacturing). ** 2. Selection of lens ** 1. ** Wavelength, zooming or not ** - It was easier to determine the working wave length of the lens and whether it needed to be zoomed. If you need to change the magnifying power during the imaging process, use a zoom lens; otherwise, use a fixed-focus lens. The most common lens worked in the visible range, but there were other applications. It was also necessary to consider whether filter measures were needed, whether it was a single color light or a multi-colored light, and whether it could avoid the influence of stray light to determine the working wave length of the lens. 2. ** Special requests will be prioritized ** - According to the practical application characteristics, the special requirements should be specified, such as whether there is a measurement function, whether a monocentric lens needs to be used, whether the depth of field of imaging is very large, etc. Although the depth of field was often overlooked, it was a factor that the imaging system had to consider. 3. ** Working distance, focal length ** - Working distance and focal length were often considered together. Generally, the resolution of the system was first determined, and then the magnifying power was obtained by combining the size of the CCD-based image. Then, the approximate distance between the object and the image was obtained by combining the spatial structure constraints, and then the focal length of the lens was further estimated. Therefore, the focal length of the lens was related to the working distance of the lens, the resolution of the system (and the size of the CCDs). 4. ** Interface Match ** - The interface types of industrial cameras and lenses must match, such as C interface, CS interface, etc., to ensure the correct connection. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
