Paper Abstract

A simple method for planar mirror pendulum pose measurement is proposed. The method only needs a LCD screen and a CCD camera. LCD screen displays calibration patterns, and the virtual images (VIs) reflected by mirror are taken by the CCD camera. By camera calibration, the pose relationships between camera and VI coordinate systems can be determined. Thus the pendulum poses of the mirror is obtained according to coordinate transition and reflection principle. This method is simple and convenient, and has a big application potential in mirror pendulum pose measurement.
