There are many parameters for industrial cameras. When choosing the right industrial camera, we must consider both the parameters of the industrial camera and the accuracy requirements of the project. So how to choose a suitable industrial camera? The following introduces the relevant knowledge of selecting an industrial camera.

1. What are the general steps for selecting an industrial camera?

The first step is to first know the system accuracy requirements and the resolution of the industrial camera;

The second step is to know the system speed requirements and the imaging speed of the industrial camera;

The third step is to consider the industrial camera and the frame grabber together, because this involves the matching of the two;

The fourth step is the comparison of prices.

2. How to use the accuracy required by the machine vision system to calculate the resolution (pixels) of the camera?

Knowing the actual detection accuracy and inferring how large the selected industrial camera can be calculated by the formula:

X-direction system accuracy (X-direction pixel value) = field of view (X-direction) / CCD chip pixels (X-direction);

Y-direction system accuracy (Y-direction pixel value) = field of view (Y-direction) / number of CCD chip pixels (Y-direction) to obtain.

Of course, the theoretical pixel value is obtained by comprehensive consideration of system accuracy and sub-pixel method;

3. How to deduce which industrial camera to choose based on the actual required detection speed?

System single operation speed = system imaging (including transmission) speed + system detection speed, although the system imaging (including transmission) speed can be theoretically calculated based on the asynchronous trigger function of industrial cameras, shutter speed, etc., the best method is to actually use software test.
