ABSTRACT

In this paper, a method for in-plane rotation angle measurement with high precision in machine vision is proposed. The presented set is composed by a calibrated line scan CMOS camera and an elaborately designed columnar pattern as rotating part under test. Computer simulation shows that tiny relative translation between the camera and columnar pattern can be ignored and thus, the experimental results demonstrate that this proposed method is reliable and robust. This approach can measure both micro and large angles.
