Before choosing an industrial camera, you must first be clear about your detection tasks, whether it is taking static or dynamic photos, how often the photos are taken, whether it is done for defect detection or size measurement, or positioning, what is the size (field of view) of the product, how much accuracy is needed, the performance of the software used, the on-site environment, whether there are other special requirements, etc.   If it is a dynamic photoshoot, what is the movement speed, select the minimum exposure time according to the movement speed, and confirm whether the camera needs to be scanned progressively.The frame rate of the camera (highest photo frequency) is related to the pixels. Usually, the higher the resolution, the lower the frame rate.Depending on the detection task, the resolution of the required industrial camera can be calculated based on the size of the product, the resolution required to be achieved, and the performance of the software used.The first thing to consider in the on-site environment is temperature, humidity, interference conditions and lighting conditions to choose different models of industrial cameras.

Give examples to illustrate the principles of selecting industrial cameras: if the inspection task is size measurement, the product size is 18mm*10mm, the accuracy requirement is 0.01mm, assembly line operation, the detection speed is 10 pieces/second, the on-site environment is an ordinary industrial environment, and interference issues are not considered.First of all, we know that it is a pipeline operation, which is relatively fast, so we choose a progressive scan camera; the field of view can be set to 20mm*12mm (considering the error of mechanical positioning each time, the field of view is appropriately enlarged than the object). If we can get a good image (for example, backlighting can be used), and the measurement accuracy of our software can take into account 1/2 subpixel accuracy, then the camera resolution we need is 20/0.01/2=1000pixcel (pixel), and the other direction is 12/0.01/2=600pixcel, which means that the resolution of our camera needs at least 1000*600pixcel, and the frame rate is 10 frames/second, so we choose 1024*768 pixels (1280*1024pixcel when the software performance and mechanical accuracy cannot be accurate), and the frame rate is above 10 frames/second.
