Abstract :
This paper proposed a solution in view of the non-contact measurement problem. In this solution, the camera is applied in the non-contact 3D measurement. Firstly, we complete the camera calibration, and then the feature point extraction and matching in turn based on the epipolar constraint criterion and gray similarity. Finally we calculate the three-dimensional coordinates of the feature points. The experimental results show that this method has a good application prospects in the industrial testing field.
