摘　　要：本文提出一种新的、基于曲面曲率的屋脊边缘检测方法。通过屋脊边缘沿最大主曲率方向的最大主曲率局部极值检测屋脊边缘,同时最小主曲率的方向就是屋脊边缘的走向。理论分析和实验证明,本文方法具有更好的性质和边缘检测效果。In this paper, a new method based on surface curvature for roof edge detection is presented. The roof edge is detected by using local extremum of maximum main curvature along the direction of maximum main curvature, and the direction of minimum main curvature is the trend of the roof edge. The effectiveness of the proposed method has been testified in theory and practice.
