How to Choose an Industrial Camera ?

How to Choose an Industrial Camera  ?

Industrial cameras are generally installed on the machine assembly line to replace the human eye for measurement and judgment. 

The digital image capture target is converted into image signals and transmitted to a dedicated image processing system. 

The image system performs various operations on these signals to extract the characteristics of the target. 

Further, on-site device operation is controlled based on the result of the determination.

1. Usually you first need to know the system accuracy requirements and camera resolution, you can use the formula :

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

Y direction system accuracy (Y direction pixel value) = field of view (Y direction) / CCD chip pixel number (Y direction)


2. Of course, the theoretical pixel value should be comprehensively considered by the system accuracy and sub-pixel method; then you need to know the system speed requirements and the camera imaging 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 camera's asynchronous trigger function, shutter speed, etc., the best method is to actually test it through software.

3. Next you want to consider both the camera and the frame grabber, as this involves matching the two:

Matching of video signals: There are two formats for black and white analog signal cameras, CCIR and RS170 (EIA), usually the capture card supports both cameras at the same time;

Resolution matching: each board only supports cameras within a certain resolution range;

Matching of special functions: If you want to use the special functions of the camera, first determine whether the board card used supports this function. 

For example, if you want to take pictures with multiple cameras at the same time, the capture card must support multi-channel. 

If the camera scans progressively, then The capture card must support progressive scan.

Interface matching : determine whether the interface of the camera and the board match. Such as CameraLink, GIGE, CoxPress, USB3.0, etc.

4. After meeting your necessary needs for testing, the final price comparison should be made.
