A pattern of coding structure light suitable for object´s surface of regularity changes

In this paper, we focus on the regular convex change surface object, and design a different encoding structured light measurement mode. This method can effectively retain the details characteristics of the surface. Firstly, a improved calculation of point-curvature is adopted to analyze and determine the relationship between the curvature values of structured light projection number. Follows, construct a three dimension measure system based on photograph geometry model. The points in different curvature changes region adopt the different modes coding structure light measurement experiment. The results show that, this structured light measurement mode we designed highlight the surface features, and decrease unnecessary point cloud data, and improve the measurement speed.
