Abstract: A new method is presented for detection of rock mass fissure, which is based on phase congruency and iterative connection of segmented lines with removing of pseudo edge. Firstly, detecting the image by phase congruency and thinning the outcome, so the segmented lines including the crack feature and the pseudo edge are obtained. And then, connecting the segmented lines iteratively according to the distance and the angle principle, making the segmented lines be continuously, and filtering the pseudo edges which can not lengthen. Experiments show that for the detection of a large volume of rock mass fissure, this method is more accurate than others.
