An iterative line segment detection procedure by graphic hardware was presented,which implemented edge detection,Hough transform,end points detection with GPU.The GPU based parallel Hough transform was designed for both θ parameter space segmentation and image space segmentation,and threads for the computation of the same θ parameter space were properly synchronized by shared memory in thread block.Experimental results prove the accuracy of the method for its iterative property,and good real-time capability because of full utilization of GPU's powerful computation effort.
