In order to effectively solve the problems in Hough transform,such as large computational and slow processing speed,presents a line extraction algorithm which based on the angle.The algorithm extracted a straight line directly in image space,by judging the straight angles formed by any of three points in image to obtain a possible straight line,and then further in the data space to determine the authenticity of this line.Results show that the algorithm has a high detection rate of a straight line and detection accuracy and speed,and less number of false line with a similar detection rate of the algorithm,comprehensive performance advantages.
