Embodiment approach

[0027] Embodiments of the present invention: the rock slope stability analysis method based on video detection of the present invention comprises the following steps:

[0028] a. Use the fisheye camera to take pictures of the slope drilling, and the captured images are transmitted to the computer for digital processing through a special cable; the measuring wheel of the fisheye camera measures the position of the fisheye camera in real time, and the position of the fisheye camera The depth value is placed in the computer;

[0029] b. The computer calculates and processes the fisheye image captured by the fisheye camera, and uses the half fisheye recovery algorithm to restore the fisheye image to the real drilling columnar graph;

[0030] c. Expand the histogram into a plan view, and splice the histograms expanded up and down in sequence to obtain a panoramic expanded view of the entire slope drilling;

[0031] d. Scan the panorama unfolded image, use the spatial analytic geom...

Abstract

The invention discloses a rock mass slope stability analyzing method based on video detection, which is characterized by comprising the steps of: shooting a slide slope drilling hole by a fisheye camera, setting a depth value of the fisheye camera in a computer; computing and processing a fisheye picture shot by the fisheye camera by the computer, restoring the fisheye picture in an actual drilling hole columnar picture; unfolding the columnar picture into a plane picture, sequentially splicing the columnar picture to obtain a full view unfolding picture of the whole side slope drilling hole;and scanning the whole unfolding picture, obtaining joint parameters by applying a space analytic geometry algorithm, and restoring the full view unfolding picture into a full view columnar picture with the joint parameters. The rock mass slope stability analyzing method can be used for judging and computing the side slope drilling hole integrally through a video detection device and a computer computing and processing system, and can be operated by a working personnel only needing being subjected to basic training so that a side slope is stably detected.

Description

technical field [0001] The invention relates to a rock slope stability analysis method based on video detection, and belongs to the technical field of rock slope stability analysis. Background technique [0002] In the prior art, the parameters for judging the type of slope and landslide and calculating its stability are all manually observed, judged and calculated. This requires a lot of time to carry out preliminary survey work, and the requirements for engineers are also very high, and rich experience must be accumulated through long hours of work and practice. In the previous technology, judging the type of side slope and landslide and calculating its stability all depended on experienced and rich engineers to carry out manual observation, judgment and calculation. This requires a lot of time to carry out preliminary survey engineering, and the requirements for engineers here are also very high, and rich experience must be accumulated through long-term work and practice...
