An image processing algorithm for automatic detecting robot of intersecting line weld to identify pathway and localization is proposed
aiming at problem that the intersecting line weld is difficult to be detected.On the basis of color space conversion and color edge detection
an image pyramids method is introduced to the Hough transform line detection algorithm
to identify the magnetic color-coded strips quickly and achieve real-time control of the attitude and motion trajectory of the robot; a multi-threshold calculation is applied to the region growing algorithm to segment the artificial mark points
and the artificial mark points are counted so as to realize localization. The effectiveness of the proposed image processing algorithm is verified through experimental results.
