Summary on calibration method of line-structured light sensor

Abstract

Line-structured light sensor (LLS) can provide the capability of three-dimensional point acquisition for robotics. As one type of 3D scanners, LLS has been widely used in many filed of robotics for its strong anti-interference, fast scanning speed and high measuring accuracy. Researchers have been studying the methods to improve the accuracy, and the operability of the LLS for many years. In this paper, calibration methods for LLS are reviewed, which covers the calibration target and the light plane calibration methods. What's more, some potential improvements are discussed and analyzed. This review paper can be used as a reference guide for researchers to choose suitable calibration method and calibration target for developing an applicable LLS.
