The latest machine vision camera selection
The selection of a machine vision camera requires consideration of the following aspects: ** 1. Type of camera ** 1. ** Line Array Industrial Cameras ** - It was suitable for capturing continuous, long production lines. For example, detecting problems on the roller, or scenes that required a large field of view or extremely high precision. It worked with an extremely long and narrow imaging feature, and the field of view was a slender strip. 2. ** Array camera ** - It was more suitable for capturing the entire scene. 3. **3D camera ** - It is suitable for specific scenarios that require 3D information acquisition. For example, in the 3D machine vision camera market research, it will involve the market size (production capacity, output, sales, output value, price, cost, profit, etc.) and industry competition analysis (raw materials, market applications, product types, market demand, market supply, downstream market analysis, supply chain analysis, major companies, market share, M & A, expansion, etc.). ** 2. Signal Type ** 1. ** Simulation camera ** - An image acquisition card was required. The resolution of a standard simulated camera was very low, usually 768 x 576, and the frame rate was fixed (25 frames per second). The data collected was an analogy signal, which was converted into a digital signal by the digital acquisition card for transmission and storage. However, it is susceptible to distortion caused by electromagnetic noise interference from other equipment in the factory (such as electric motor or high-voltage cable). As the noise level increases, its dynamic range (the ratio of the original signal to noise) will decrease, affecting the amount of information transmitted to the computer. 2. ** Digital camera ** - What was collected was a digital signal that was not affected by electromagnetic noise. The dynamic range was higher, and it could transmit more accurate signals to the computer. ** 3. Determination ** The resolution of the camera was chosen according to the system's requirements. For example, to detect the scratches on the surface of an object, the size of the object required to be shot was 10mm × 8mm, and the required detection accuracy was 0.01mm. Assuming that the field of view to be shot was 12mm × 10mm, then the camera that should be chosen had a minimum resolution of (12/0.01)×(10/0.01) = 1200x1000, which was about 1.2 million pixels. Generally, the lowest resolution camera required was determined according to the actual accuracy inspection requirements. The common camera had 1.3 million resolution to choose from. ** 4. Chip Type ** 1. ** Charge Coupled Device (CCD-Chip) camera ** - If the object to be shot is moving and the object to be processed is also moving in real-time, it is more suitable to choose a camera with a CCD-chip. 2. ** Complimentary Metal Oxide Silicon (LCD) chip camera ** - If the object being photographed was moving very slowly, the distance of the object's movement was very small within the set exposure time of the camera, which was converted to a 1 - 2-pixel-sized image, then the use of a LCD camera was also suitable (if not for measurement). Moreover, if the manufacturer's LCD camera used the frame exposure method, it could also be used as a CCD. However, if the deviation was more than 2 px (caused by the movement of the object), the image taken by the object would have smear, so it was not suitable to choose a LCD camera. ** 5. Other Key Elements ** The frame rate, color depth, dynamic range, and sensitivity of the camera were key factors in the selection. The quality of the lens, the optical format of the camera, the number of graphics, and the type of interface (such as USB, ether, or GigE) were also considerations that could not be ignored when selecting the camera. At the same time, for the line array industrial camera, parameters such as line frequency, line height, and trigger method also needed to be considered. The line frequency was the camera's shooting speed, and the line height was based on the application requirements to determine how many lines to capture an image (that is, the image's "high" resolution). The trigger methods were line trigger (suitable for scenes where the motion speed was not uniform or required some special imaging technology, such as long and short exposure HVR, time-sharing stroboscopic, etc.) and frame trigger (suitable for shooting objects with relatively uniform motion. After the frame trigger, the line array camera would continue to shoot at the set line frequency until it reached the specified line height). <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>

What is machine vision for?
Machine vision was an inspection machine equipped with sensory visual instruments (such as autofocus cameras or sensors). The proportion of optical inspection instruments was very high. Its effects were as follows: 1. ** Detection **: - It was used to detect the defects of various products. - Nearly 80% of industrial vision systems were mainly used for inspection, including improving production efficiency, controlling product quality, collecting product information, etc. The product classification and selection were also integrated into the inspection function. The vision system checks the products on the production line to determine whether they meet the quality requirements. According to the results, the corresponding signal is input to the host computer. If a non-qualified product is found, the alarm will alert and exclude it from the production line. The result is the source of quality information for the CAQ system, which can also be integrated with other CIMS systems. 2. ** Location **: - Calibrating and positioning materials on an automated production line. - The machine vision system can locate the position and direction of a machine (such as an unmanned truck), ensure that the machine is on the correct path, and transmit the position and direction data to the controller in real time to perform the task. 3. ** Simulating human vision **: - Using a computer to realize the human visual function, that is, to identify the objective three-dimensional world. The mechanism was to use optical systems, cameras, and image processing software to simulate human visual abilities, make corresponding decisions, and finally complete the decision through the execution device in the command machine. 4. ** Special applications **: - In some special application scenarios, it can effectively avoid personal safety risks, or it can be used to replace artificial vision in situations where artificial vision is difficult to meet the requirements. It also avoided direct contact between the detection system and the inspected item, preventing damage to the item and contamination of the clean room. There was also no maintenance and cost of mechanical parts wear and tear. "A Short History of the Future: Legends of the Intelligent Era" was equally exciting.
