Problems solved by technology

The method is to first set up a suitable fixed site, a fixed point target, and set a reflector on the monitoring target, fix the laser scanner on the fixed point pier, connect the computer, power supply, camera and other equipment, start collecting data, and compare different time The scanning file under the sequence completes the monitoring task according to the change of the observation object relative to the reflection center in different time series coordinates, but the reflector is required to be fixed during the whole monitoring process. For complex terrain, the arrangement of fixed points and reflectors is difficult and very difficult. Difficult to stay still, if the reflector moves, the accuracy of deformation detection decreases

Embodiment Construction

[0027] The present invention will be further described below in conjunction with accompanying drawing.

[0028] Such as Figure 1-5 As shown, a mine slope monitoring method combining three-dimensional laser scanning and GPS of the present invention is characterized in that: the three-dimensional laser scanner system is organically combined with the GPS monitoring and positioning system to accurately monitor slope geological hazards ,Specific steps are as follows:

[0029] (1) First, install the monitoring pile I1 on the central axis of the slope to be monitored. The monitoring pile I1 includes a fixed base 1-1, and a centering hollow rod 1-2 set on the middle and upper part of the fixed base 1-1. On the support plate 1-3 around the fixed base, two support bolts 1-4 in the shape of a cross are welded at the upper, middle and lower positions of the centering hollow rod 1-2 respectively. Bolt holes are provided on the support plate 1-3, and the support plate 1-3 is fixedly conn...

Abstract

The invention relates to a three dimensional laser scanning-GPS-combined side slope monitoring method. The monitoring method is characterized in that a three dimensional laser scanner system and a GPS monitoring positioning system are combined and are used for accurate monitoring of side slope geologic hazard. The method can accurately detect and forecast mine side slope geologic hazard, improve side slope monitoring intelligence and prediction effects, realize real-time monitoring of side slope deformation, accurate prediction of side slope deformation trend and precaution of geologic hazards such as side slope displacement and falling and guarantee mine production safety.

Description

technical field [0001] The patent of the present invention relates to the technical field of geological disaster monitoring, in particular to a mine monitoring method combining three-dimensional laser scanning and GPS. Background technique [0002] Slope monitoring is an important measure to ensure the safe construction of roads, railways, open-pit mines, reservoir banks, etc., and the open-pit mine slope has been in the dynamic excavation process for a long time. How to carry out long-term, effective and accurate slope monitoring is a key issue for mines. A difficult problem that enterprises urgently need to solve. [0003] At present, there are many methods for slope displacement monitoring, such as geodetic observation, instrument observation, GPS observation, close-range photogrammetry and so on. According to the equipment installation collection method, it can be divided into two categories: contact measurement method and non-contact measurement method. [0004] The G...
