Compared to the traditional method, used the orthophoto Measurements based on the UAV platform to detect the complex environment can greatly improve the efficiency of the work. Firstly, used the UAV's strong mobility to collect environment information efficiently; Secondly, input the collection of the image to the corresponding software and built the three-dimensional (3D) model; finally, synthesized the generated model to create an accurate 3D geographic model. In this paper, use orthophoto
