Industrial cameras are mainly aimed at batch industrial applications, while ordinary cameras (SLR cameras, mobile phone cameras) are aimed at ordinary consumers.
The performance of industrial cameras is stable and reliable, easy to install, compact in structure, strong and not easily damaged, have a long continuous working time, and can be used in poor environments. It is difficult for ordinary cameras to work for a long time or for several days.
The shutter time of industrial cameras is very short and can capture high-speed moving objects.
The image sensor of industrial cameras is a progressive scan, while the image sensor of ordinary cameras is an interlaced scan. The production process of progressive scan image sensors is relatively complex, the yield is low, and the shipment volume is small. Only a few companies in the world can provide such products, such as Sony and Dalsa, and they are expensive.
The frame rate of industrial cameras is much higher than that of ordinary cameras. Industrial cameras can take ten to hundreds of pictures per second, while ordinary cameras can only take 2 to 3 pictures.
Industrial cameras output raw data with a relatively wide spectral range, which is more suitable for high-quality image processing algorithms, such as machine vision applications. The spectral range of pictures taken by ordinary cameras is only suitable for human vision, and they have been compressed by jpeg, so the image quality is poor, which is not conducive to analysis and processing.
The main parameters of industrial cameras
1. Resolution (Resolution): The number of pixels (Pixel) that the camera collects each time the image is collected.
2. Pixel Depth (Pixel Depth): The number of bits without pixel data. Generally, 8bit is commonly used. For digital cameras, 10bit, 12bit, 14bit, etc. are generally used.
3. Data processing method: Industrial cameras usually send images to other equipment for post-processing while shooting, and can work for days or months for a long time.
4. Control method: Industrial cameras are usually controlled by computers to take pictures, record videos, adjust parameters, and other functions.
5. Spectral response characteristics: The general response range is 350nm-1000nm. Some cameras add a filter in front of the target to filter out infrared light. If the system needs to be sensitive to infrared light, remove the filter.
6. Interface type: Camera Link interface, Ethernet interface, USB interface output, the latest interface is the CoaXPress interface.
