Six key points for industrial camera selection:

（1）Resolution: Determined by the size of the field of view and the need for measurement accuracy.

（2）Frame rate and exposure time: Ensure high speed acquisition to avoid ghosting.

（3）Color: Black and white cameras are more commonly used unless true color information is needed.

（4）Pixel depth: 8bit is basically satisfied, 16bit is used for high precision detection.

（5）Interface type: Digital interface is better than analog interface.

（6）Chip size: as a reference for lens selection.

Lens selection of nine major points:

1. Focal length: determines the size of the field of view, affecting the depth of field and aberration.

2. Field of view (FOV): choose a lens slightly larger than the field of view of the object being measured.

3. working distance: to ensure that the lens to the object is the right distance.

4. Resolution: match the camera resolution to ensure clear imaging.

5. depth of field: small aperture and low magnification lens to increase the depth of field.

6. Aperture: Controls the amount of light passing through, affecting exposure and image quality.

7. Interface Type: Match the camera interface, e.g. C/CS interface.

8. Aberration: choose a low aberration lens, or reduce the effect by calibration.

9. Chip size and camera interface: make sure the lens is compatible with the camera.

Practical application principles:

1, field of view, magnification and working distance: comprehensive consideration of the measured object requirements.

2, depth of field requirements: choose small aperture and low magnification lens.

3, light source with: to ensure image quality.

4、Installation space: consider the actual installation conditions.

Understanding these points will help to choose the right industrial cameras and lenses according to the project requirements and improve the performance and cost-effectiveness of the machine vision system.
