Claims24
A method of inspection, comprising:
- capturing stereo image data inclusive of a direct part marking (DPM) code on an object;
- rectifying the captured stereo image data to produce rectified image data from the captured stereo image data;
- generating a depth map inclusive of the DPM code from the rectified image data;
- and
- reading the DPM code from the depth map.
