A line feature visual positioning method and system based on multi-stage line segment screening and fusion in a strong light environment

Abstract

The application discloses a line feature visual positioning method and system based on multi-stage line segment screening and fusion in a strong light environment. The multi-stage line segment screening and fusion strategy can effectively eliminate noise line segments, connect and fuse broken line segments, and make the extracted line segments more uniformly and completely distributed in the global range of the image, so that the robustness of line feature matching is enhanced, and the accuracy and stability of visual camera positioning in the strong light environment are effectively improved.
