Aiming at the shortcomings of probabilistic Hough line detection algorithm that the detec-tion rate needs improving and the detection accuracy is easily interfered by other features and conti-nuous discontinuous lines,an improved probabilistic Hough line detection algorithm was proposed.The improved algorithm focused on several possible intervals of the straight line,improved the detec-tion speed and accuracy,monitors and eliminates continuous discontinuous lines in the whole process of straight line detection,and improved the anti-interference ability of the algorithm.In 100 sets of experimental verification of the edge line detection of aluminum ingots,the average detection rate of the improved algorithm is 1.77 times of the original algorithm,while the precision rate is 1.45 times.The detection rate and effect of the improved algorithm on other pictures is significantly improved in comparison with that of the original algorithm.
