Slope fractured rock mass information acquisition method based on image recognition

Abstract

The invention provides a slope fractured rock mass information acquisition method based on image recognition. The method is based on landslide fractured rock mass examples in alpine and gorge areas. Aplurality of fractured rock mass images are acquired by a high-definition digital camera, vectorization is carried out on particles in an image, particle geometrical parameters, fragmentation lumpiness indexes, block fractal dimensions and curvature coefficients of particle distribution are calculated and extracted, geometrical characteristic information and development distribution rule information of fragmented rock mass particles are obtained, in-situ rock mass shear strength information is estimated, and therefore the fragmented rock mass quality is rapidly evaluated. The method effectively solves the problems that in the prior art, slope fractured rock mass information is not easy to obtain in areas with traffic inconvenience such as alpine and canyons, and the quality of the fractured rock mass cannot be effectively evaluated.

Description

technical field [0001] The invention belongs to the technical field of rock mass information acquisition, and in particular relates to an image recognition-based method for acquiring slope fragmented rock mass information. Background technique [0002] In the structurally active alpine and canyon areas such as the Qinghai-Tibet Plateau in my country, experienced complex orogeny processes such as lateral shrinkage, vertical thickening, and uplift to form mountains, developed multi-level, multi-stage, and multi-type superimposed structural deformations, resulting in rock masses inside the slope In addition, strong earthquakes occur frequently in these areas, for example, there have been more than 30 strong earthquakes of magnitude 7 or above in the past century, which promotes further fragmentation of the rock mass of the slope and greatly reduces the stability of the slope in this area. [0003] Although new technologies such as ground radar and 3D laser scanning continue to d...
