In order to improve the robustness of image processing for robots' linear trajectory measurement system, the paper studies the technique of feature points' recognition in laser strip image based on line structured light, and presents a line segmentation method on the base of seed points fitting and line growing. It resolves the problem for automatically obtaining each fitting line end-points in various conditions, and improves adaptability to changing environment for robot work and precision. Many experiments show that the method has good robustness.
