[0035] Before collecting image data, a real-life survey of the surveying target is conducted, and points that exist naturally in the scene and are not prone to spatial surveying errors are selected as natural image control points. Target points are artificially arranged as artificial image control points, and the three-dimensional coordinate information of the image control points is collected; based on the close-up photogrammetry method, image control points are arranged, the flight route of the drone is planned, and a high-resolution image sequence of the target is obtained. Based on the high-resolution image sequence of the target, the motion recovery structure method is used to perform three-dimensional reconstruction of the point cloud to obtain the initial three-dimensional point cloud model. Three-dimensional point cloud data has the characteristics of disorder, sparsity, and unstructuredness, which also determines that even if the point cloud data contains information such as the three-dimensional spatial attributes of the object, it needs to be processed by a series of algorithms to extract the required information from it, such as point cloud preprocessing, point cloud segmentation, point cloud registration, etc., to create a spatial index for the initial point cloud model, filter noise, and downsample to obtain a point cloud model that is easy to calculate, and cluster and segment the point cloud model to obtain a local point cloud model of the structure.
