摘要
该文依据高陡危岩体裂缝在无人机影像上呈现的灰度和空间特征,提出一种利用数字图像和矢量图形处理等技术,从无人机影像中提取出危岩体裂缝轮廓信息的方法,并结合实际工程项目研发了高陡危岩体裂缝信息采集系统。实验表明,采用该方法对于分析危岩体裂缝时空变化规律、评价危岩体稳定性、灾害预警预报以及防灾减灾具有重要的实际意义。
According to the grey scale and spatial characteristic of fracture of high and steep dangerous rock on UAV images,a method that it can extract the contour information of fracture of dangerous rock from UAV images by using the digital image and vector graphics processing techniques is proposed,and combining with the practice engineering,the information collection system of high and steep dangerous rock is developed.The experiments show that this method has great practical significances for analyzing the spatio-temporal variation rule of cracks in dangerous rock mass,evaluating the stability of dangerous rock mass,early warning and predicting disasters,and preventing and reducing disasters.
