As a non-contact three-dimensional measurement method, line structured light measurement is widely used in three-dimensional shape measurement due to its fast speed, high accuracy, and convenient implementation. The line structured light extraction is one of the most important step in the line structured light measurement system. Most traditional algorithms are based on the Hessian matrix or the light intensity distribution of the light strip section to extract the center. In this paper, a novel algorithm based on ridge tracking is proposed to extract the center of the light strip, the approximate direction has been used to estimate the direction of the light strip. Experiments have proved that this algorithm can be applied to the extraction of light strips in a variety of scenes, and has good accuracy and noise resistance.
