| Abstract: | An object oriented method for building crack extraction based on laser point cloud is proposed.Based on laser point cloud segmentation,the characteristics of angle between horizontal plane and segmented plane,area and patch similarity are calculated.According to the prior knowledge of building cracks,object oriented extraction method is used to identify the cracks from point cloud.The experimental results show that the proposed method can effectively extract the building cracks. |
