Other industrial cameras
In addition to the above-mentioned area array cameras, line array industrial cameras, PDA industrial cameras, and wide-format industrial cameras, there were many other types. In terms of sensor types, there were industrial cameras with CCD-type and CMOS-type sensors. Among them, CMOS-type image sensors had gradually become mainstream. CMOS-type sensor cameras with global shutters were more suitable for capturing dynamic images, and CMOS-type cameras with rolling shutters for capturing still images could be considered. From the interface type, it was an industrial camera with a USB 3.0 interface. However, although its transmission speed was fast, the transmission distance was limited. It was not recommended to use it when it was more than 5 meters. Color cameras were used for detection targets that required color recognition. If color recognition was not needed, black-and-white cameras were more cost-effective. Different types of industrial cameras are suitable for different industrial inspection scenarios. When selecting, factors such as resolution, sensor type, interface, color, etc. should be considered to meet specific requirements such as detection accuracy, field of view, and data transmission distance.

Internal and external parameters of industrial cameras
The intrinsic parameters of the camera were parameters related to the camera's own characteristics, such as the focal length of the camera, the size of the camera, etc. The intrinsic parameters of the camera were parameters in the world coordinate system, such as the position of the camera, the direction of rotation, etc. The camera was a map between the world coordinates and the pixel-based coordinates. When the world coordinates and the pixel-based coordinates of the control points were known, the map could be calculated. After the calculation, the world coordinates of the control points could be inferred from the pixel-based coordinates, and then subsequent operations such as measurement could be carried out. This kind of calibration-based method was also known as hidden parameters calibration-based method because it did not calculate the internal parameters of the camera (such as the focal length of the camera, the distortion coefficient of the camera, etc.). In the process of image measurement and machine vision applications, in order to determine the relationship between the three-dimensional geometric position of a point on the surface of a spatial object and its corresponding point in the image, a geometric model of the camera image must be established. These geometric model parameters are the camera parameters. Under most conditions, these parameters need to be obtained through experiments and calculations. This solution process is called camera calibration1. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Market analysis of imported industrial cameras
The following is an analysis of the imported industrial camera market: ** I. Market scale and trend ** 1. ** Overall market size ** - From the perspective of the China market, the situation of imported industrial cameras has changed from 2017 to 2019. Although the number of imported cameras has not increased much, the amount of imported cameras has increased significantly. For example, in 2018, the number of imported cameras was 8159 units, and the import amount was 44.8274 million yuan. From January to October 2019, the number of imported cameras and the import amount had exceeded the whole year of 2018, showing that the market value of imported industrial cameras was constantly increasing. 2. ** Market growth factors ** - With the explosion of the machine vision and artificial intelligence industries, the market demand for industrial cameras increased, which also promoted the development of the imported industrial camera market. ** 2. Market share and competitive landscape ** 1. ** Market concentration of different types of cameras ** - In the smart camera market, the global market concentration was much higher than the board camera market. For example, Cognex and Keyence, which were the first to lay out smart cameras, currently accounted for more than 70% of the market, while the top eight companies in the board camera market only had a combined market share of 61%. 2. ** Relationship between regional demand distribution and import market ** - In China, from a regional perspective, the Yangtze River Delta and the Pearl River Delta contributed 70% of the market demand, and the Bohai Rim region contributed about 15% of the market demand. Part of these needs were met by imported industrial cameras. The imported industrial cameras occupied a certain share of the China industrial camera market demand, especially in the high-end market demand. Due to the advantages of foreign products in terms of technology, imported industrial cameras had a large market space. ** 3. The advantages and disadvantages of the product ** 1. ** product advantage ** - Foreign imported industrial cameras had certain advantages in terms of technology. For example, in the field of smart cameras, well-known foreign companies had experience in developing visual software. They usually came with corresponding customized software to facilitate system developers to program smart cameras. For example, the supporting software EasyBuilder for Cognex's In-Sight series of smart cameras had very good functions. Moreover, in terms of industrial machine vision cameras, manufacturers such as Teledyne, Basler AG, and Cognex Corporation accounted for more than half of the global market. The products of these brands were highly competitive in the global market and may have advantages in terms of technology development and product quality. 2. ** Weakness of the product (targeted at the China market)** - The application of foreign products in the China market was not targeted enough. Although the hardware and software advantages of foreign products were obvious, the lack of in-depth development for the China market limited its further expansion in the China market to a certain extent. ** 4. Price factor ** - The price of imported industrial cameras was relatively high. Taking smart cameras as an example, foreign products were priced at a higher level due to their hardware and software advantages. This affected the further expansion of their market share to a certain extent, and also provided opportunities for domestic companies to enter the low-end market. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Analyzing the Digital Interface Type of Industrial Cameras
The digital interface types of industrial cameras are mainly as follows: 1. **USB2.0 interface **: A high-resolution digital camera product that uses a high-speed USB2.0 interface and a large-area array of a LCD image sensor. No additional acquisition equipment is needed to obtain real-time uncompressed video data and image capture. It is fully compatible with all application environments of MicroSoft, and is suitable for various applications of computer image acquisition. It uses a master-slave structure for half-dual transmission with a band width of 60 Mbit/s, which can meet the requirements of commonly used 1/4-inch, 1/3-inch, and 1/2-inch image sensors. 2. **CameraLink interface **: It uses a parallel architecture. Under the full 8 -channel configuration, the transmission band width can reach 680MByte/s, which can solve the problem of large data transmission. However, it requires an image acquisition card, which is costly. 3. **1394 interface (including 1394A and 1394B)**: It can provide up to 45W of power and adopt a more efficient peer-to-peer network architecture. Under this architecture, the peripheral could coordinate the bus conflict to better control the data transmission, but it also needed to connect to the acquisition card, which was costly. 4. **GigE (GigE) interface **: It has great advantages in long-distance transmission, but the cost is high. 5. **USB3.0/3.1 interface **: It is also a type of digital interface for industrial cameras. Compared to USB2.0, it may have a further improvement in data transmission speed.(The reference materials do not mention the features of USB3.0/3.1 in detail. It is supplemented based on general knowledge.) <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
HD Cameras and Cameras
A high-definition camera was a digital device that could capture high-quality, high-definition images. Its image resolution could reach 1280*720 (corresponding to 720 lines of interlaced scanning) or 1920*1080 (corresponding to 1080 lines of interlaced scanning). High-definition cameras were divided into two types: the early HD video cameras, which used magnetic tape as the recording medium, and the AVCHD video cameras, which had a variety of recording media such as discs, flash memory, and hard disks. As for the camera, the reference materials did not specifically give the concept of the camera and other related content, but from the mention of some video cameras, hand-held cameras and other equipment, it can be inferred that they have similarities with the function of the camera. They are both used for shooting and recording images, but there may be differences in the use of the scene, professional level, functional focus, etc. For example, some video cameras might be equipped with specific lenses, microphones, and other equipment to meet different shooting needs. For example, the SonyPXW-X280 video camera had 17x zoom and wireless functions, and the PXW-Z150 hand-held 4K camera was equipped with an omni-directional three-dimensional electret microphone. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Professional Cameras and Home Cameras
There were many differences between professional cameras and home cameras: ** 1. Image quality ** 1. ** hardware performance ** - Professional cameras were usually equipped with higher-level sensors, lenses, and other hardware components. For example, in low-light environments, professional cameras such as the SonyFX3 had better performance in low-light environments, allowing them to capture clear, low-noise images in darker environments. However, home cameras might have more noise in low-light environments, and the quality of the picture would drop significantly. - The quality of professional cameras was often higher, with a wider focal length coverage, smaller distortion, and better optical performance. They could meet a variety of shooting needs, such as the conversion from large scenes to close-up shots in movie scenes. The lens of a home camera was more suitable for daily shooting scenes, and the focal length was relatively fixed or the coverage was narrow. 2. ** Color reproduction ability ** - Professional cameras were more accurate in color science and could accurately restore the true colors of the scene. They could provide more room for adjustment through professional color configuration files such as Log mode. Although home cameras also had a certain degree of color optimization, it was more to directly output a better image. The flexibility and accuracy of color adjustment were relatively low. ** 2. Function ** 1. ** Manual control ** - Professional cameras provided a variety of manual control functions, such as manual focus, manual aperture, manual shutter speed adjustment, and so on. This allowed professional photographers to precisely control the shooting parameters according to the shooting needs to achieve specific shooting effects. For example, when shooting dynamic scenes, the motion blur effect could be controlled by precisely adjusting the shutter speed. Home cameras were mostly automatic, with limited manual functions. They were more focused on ease of use and convenient for ordinary users to operate. 2. ** Special Function ** - Professional video cameras might have some special functions, such as multi-format recording, which could record in different video format and resolution to meet different post-production needs. Some professional video cameras also supported the expansion of external devices, such as external audio equipment to obtain higher quality sound recording. Home cameras were mainly focused on meeting the basic functions of daily family shooting, such as simple video recording and photo functions. There were relatively few special functions. ** 3. Durability and stability ** 1. ** Airframe structure ** - Professional cameras usually used more durable body materials to adapt to a variety of complex shooting environments, such as collisions and bad weather when shooting outdoors. For example, some professional cameras-on-shoulders were designed to withstand long-term use and transportation. Household video cameras were more portable, the body material was relatively light, and the durability was not as good as professional video cameras. 2. ** Anti shake performance ** - Although some home cameras also had anti-shake functions, the anti-shake technology of professional cameras was often more advanced. For example, some professional movie cameras used 5-axis anti-shake technology, which could compensate for the image shake caused by hand shake or moving shooting in multiple directions. It could provide a more stable image when shooting scenes such as hand-held shots. ** 4. Price ** 1. ** Price Range ** - Professional cameras were usually more expensive due to their high-performance hardware, complex functions, and professional design. Professional HD cameras such as the SonyPXW-Z280 could cost tens of thousands of yuan. Home cameras were more affordable, ranging from a few hundred yuan to thousands of yuan. For example, home cameras such as the Sony-HMD-CX405 were affordable to ordinary consumers. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Cameras, cameras don't
There were many differences between cameras: 1. ** Recording Method **: - The camera used optical and chemical recording methods. It was a device that used optical principles to record images. - The camera used an electronic recording method to convert optical image signals into electrical signals for storage or transmission. 2. ** Appearance **: - Cameras were usually large and highly integrated, while video cameras were small and low integrated. - Cameras had many functions. Many of them were video-recording machines that could record sound and images at the same time. The built-in microphone had good sound quality. It usually came with a monitor, an HD mirror, and a hood. Some of them came with a fill light, but they had few ports and did not support the expansion of professional accessories. The camera itself did not come with accessories, but it could support the installation of a large number of third-party accessories. There were many professional ports that could be connected to a variety of equipment. 3. ** Usage differences **: - Cameras were specially developed for movie applications, and most movies used cameras. - The camera was developed for television applications and could be used in television programs (such as news programs and studio programs), television dramas, documentaries, feature films, and other programs. However, in the modern film and television industry, there was a trend of combining movies and television. The two could be used in some shooting scenes. 4. ** Price difference **: Cameras are generally more expensive, while video cameras are relatively cheaper. 5. ** Different Image Quality **: The image quality of the camera is slightly worse than that of the video camera. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
