文摘
- •
We had performed mechanical QA using digital camera.
- •
For use of camera, calibration should be prerequisite for quantitative measurement to reduce distortions.
- •
Both camera and camera calibration provided the method for mechanical QA without loss of precisions.
- •
We suggest how to calibrate camera and how to do mechanical QA using camera.
