基于图像处理的滑坡后缘裂缝运动轨迹分析
Crack Trajectory Analysis of Trailing Edge of Landslide Based on Image Processing
摘要
Abstract
The trajectory analysis of the trailing edge crack of landslide is very important for landslide monitoring and early warning. For the crack zone at the trailing edge of landslide, a landslide trailing edge based on the largest interclass OTSU algorithm, Canny operator and target object feature recognition is proposed. The crack detection method obtains the crack displacement of the trailing edge of the landslide by preprocessing the rim slope crack image, morphological processing with edge detection and edge trajectory comparison. After testing, this method can effectively detect the cracks at the trailing edge of the landslide on the host computer(based on QT platform development)and can discriminate the motion trajectory under the theoretical model, which can provide support for the landslide hazard warning.关键词
