In machine vision and industrial measurement, the first thing to understand is the detection task, whether it is a static photo or a dynamic photo, how often the photo is taken, whether it is for defect detection or size measurement or positioning, and what is the size of the product (shooting field of view). , How much accuracy needs to be achieved, the performance of the software used, how the site environment is, and whether there are other special requirements.
If it is a dynamic photo, what is the motion speed, select the minimum exposure time and whether a progressive scan camera is required according to the motion speed; and the camera's frame rate (highest shooting frequency) is related to the pixel, usually the higher the resolution, the lower the frame rate. Different brands of tof cameras have slightly different frame rates.
According to the different inspection tasks, the size of the product, the resolution to be achieved, and the performance of the software used, the resolution of the required industrial camera can be calculated; the most important factors to consider in the field environment are temperature, humidity, interference and lighting conditions to choose different tof camera.
