Embodiment 1

[0062] The application of the present invention to the quick geological catalog of a high cut slope will now be described in detail as an example, and it also has a guiding effect on the application of the present invention to the rapid geological catalog of other engineering slopes.

[0063] The bedrock of a high cut slope has a blocky rock mass structure with poor rock mass integrity. There are multiple sets of structural planes with different inclinations, and it is easy to form wedge-shaped blocks with different structural plane combinations.

[0064] see figure 1 , a rapid geological cataloging method for a high cut slope based on 3D point cloud reconstruction technology, including the following steps:

[0065] Step 1. UAV information collection;

[0066] Step 2. Motion recovery structure process: use scale-invariant feature transformation principle and beam adjustment method to reconstruct the 3D scene point cloud of the photo set, and use multi-view stereo vision and p...

Abstract

The invention discloses a rapid logging method for high cut slope geology based on a three-dimensional point cloud reconstruction technology. The method comprises the following steps: 1, acquiring data of the unmanned aerial vehicle; 2, carrying out a motion recovery structure process; step 3, post-processing the point cloud data; and 4, identifying and extracting a structural surface. According to the invention, the problems of low working efficiency and high cost of a high-precision three-dimensional laser scanner in the traditional geological logging are solved; the method has the advantages of low cost, easiness in operation, good effect and high efficiency.

Description

technical field [0001] The present invention relates to the field of three-dimensional simulation technology, in particular to a method for rapid cataloging of geological bodies based on three-dimensional point cloud reconstruction technology, more specifically, it is a high-cut slope geology method based on unmanned aerial vehicle three-dimensional point cloud reconstruction technology Quick catalog method. Background technique [0002] Three-dimensional laser scanning technology has been used in the industry for many years, and the technology is becoming more and more mature. At present, due to the high cost of 3D laser equipment, 3D laser scanning has not been fully promoted, and engineers and technicians still maintain the traditional habit of geological cataloging, which requires a lot of time and energy to draw engineering geological display maps. The rapid development of software related to UAV collection of high-definition images with coordinates and motion reconstr...
