Method for detecting a vehicle sunvisor's state
A method for detecting a vehicle sunvisor's state includes obtaining a detected image; conducting a gray-scale preprocessing on the detected image, to obtain a gray-level image; conducting a main connected region extraction on the gray-level image, and calculating a geometric feature and a rectangle similarity of each main connected region; conducting a horizontal long edge extraction on the gray-level image, and conducting feature matching operation between horizontal long edges and main connected regions to obtain a region edge matching relationship; determining the sunvisor's state based on the region edge matching relationship, the geometric feature of main connected regions and rectangle similarity of main connected regions. The present invention can be widely applied in the field of image process.
