Abstract

Abstract

An automatic localization method of light strips in multi-planar structures is proposed in order to solve the problem that it is difficult to distinguish light strip regions of irregular surface in rudder angular measurement based on the vision system of line-structured light. Firstly, the sub-pixel centers of curvilinear structures are extracted by Steger algorithm. Secondly, pieces of line segments are detected and labeled using line constraints and distance constraints to calculate the distances and orientations of points. Finally, different planes are located according to light strips positions. Experimental results show that the presented method is convenient and effective.
- structured light,
- strip image,
- angle measurement,
- planar recognition
