Claims18
An inspection method for a camera, the camera being configured for obtaining a detection image of workpiece conveying by a roller, the roller comprising:
- a roller body, comprising a roller surface for supporting a workpiece;
- and
- a calibration pattern located on the roller surface of the roller body and avoiding the workpiece, the calibration pattern being configured for camera inspection, the method comprising:
- obtaining a detection image having a calibration pattern;
- determining location information of the calibration pattern in the detection image;
- and
- judging whether a location of the camera is abnormal based on the location information of the calibration pattern.
A camera inspection apparatus, the apparatus comprising:
- a camera and a roller, the camera being configured for obtaining a detection image of workpiece conveying by the roller, the roller having:
- a roller body, comprising a roller surface for supporting a workpiece;
- and
- a calibration pattern located on the roller surface of the roller body and avoiding the workpiece, the calibration pattern being configured for camera inspection;
- the apparatus further comprising:
- a computer programmed to operate as an obtaining module, configured to obtain a detection image having the calibration pattern;
- the computer being further programmed to operate as a determination module, configured to determine location information of the calibration pattern in the detection image;
- and
- the computer being further programmed to operate as a judgment module, configured to judge whether a location of the camera is abnormal based on the location information of the calibration pattern.
