Calibration of Line Structured Light Scanning Sensor Structure Parameter Integration
摘要
Abstract
In order to mark line structured light scanning sensor structure parameters accurately,this paper presents a new method for the integration structure parameters calibration of line structure light scanning sensor and establishes the mathematical model of line structured light scanning sensor. According to the Zhang Zhengyou camera calibration based L-M algorithm,this algorithm can complete the intrinsic and extrinsic parameters of the camera quickly and ac-curately. On this basis,author introduces auxiliary line laser and extracts two laser intersection to finish lines structure light plane calibration repeatedly. This paper also introduces the method of obtaining the laser point and accurately extracting the intersection point coordinate. Relevant experimental results verify the feasibility of this method. The sys-tem accuracy is better than 24μm,meeting the requirement of actual measurement.关键词
