Embodiment Construction
[0038] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.
[0039] refer to figure 1 , which is a schematic flowchart of the method for extracting geological structure planes based on optical images provided by the present invention, including specific steps.
[0040] Step 1, collect optical image sequences of geological objects, generate dense point clouds from them, and obtain the real spatial position of dense point clouds.
[0041] In the embodiment of the present invention, the sparse point cloud corresponding to the optical image sequence is generated based on the motion recovery structure, and the dense point cloud is reconstructed through multi-view clustering and dense matching based on the patch model.
[0042] In the embodiment of the present invention, through the control points arranged on the geological objects, the total station is used to measure the object space coordinates of the con...
