Embodiment Construction
[0026] The present invention will be further described below with reference to the accompanying drawings and in conjunction with specific embodiments.
[0027] A bridge investigation method, comprising the following steps
[0028] Step 1) Obtaining data, including obtaining 3D ground data, 3D geological model data, and generating a 3D ground solid surface model;
[0029] 1-1) Obtain remote sensing, aerial survey, multi-temporal high-resolution satellite stereo images and airborne LiDAR system (Light Detection And Ranging, abbreviated as LIDAR) scanning data; the survey area should follow the route plan, and the starting point and end point should go beyond the bridge. , The position of the exit of the cave (20~100m), using aerial surveying, remote sensing with elevation data at a ratio of 1: (500~1000) topographic map or satellite imaging with a resolution of 0.2~1.0m high-resolution satellite stereoscopic image, High-resolution satellite stereo images should have rational fu...
