Abstract

Considering the requirement of measurement for video probe, a method that uses line-structured laser to measure points, lines and surfaces of the object is presented. The line-structured light imaging model is built, where the linear laser is used as an auxiliary light source irradiating on the surface of the object. Compared to the object image, the proportional coefficient is calibrated with multiplying factor in different distance and laser line position. The geometry parameters are calculated based on the measurement platform. The experimental results show that the measuring error is less than 10%, and the method is suitable for the requirements of the video probe.
