Underground space laser 3D imaging device and imaging method

Abstract

The invention discloses an underground space laser 3D imaging device and an imaging method. The imaging device comprises a vertical telescopic rod, a control box, a first stepping motor, a second stepping motor, a rocking arm, a laser emission receiver, a magnetometer and an upper computer, wherein the control box is connected with the lower end of the vertical telescopic rod; the first stepping motor and the second stepping motor are arranged at the lower end of the control box; the horizontal and vertical rotation of the laser emission receiver can be achieved; the magnetometer is fixedly connected with the laser emission receiver and is used for measuring azimuth information of the laser emission receiver; the upper computer is used for receiving spherical scanning data obtained by thelaser emission receiver, and processing the data to obtain imaging information. According to the underground space laser 3D imaging device and the imaging method, the functions of other underground detection device are optimized, and the geometrical morphology and the space change of an underground space can be detected intuitively and accurately.

Description

technical field [0001] The invention relates to the field of underground space geometric form detection, and in particular provides an underground space laser 3D imaging device and an imaging method. Background technique [0002] The underground empty area is a "cavity" created by human excavation or natural geological movement below the surface. The existence of the empty area makes the safe production of mines face a great safety problem. Laser detection 3D imaging technology can intuitively and accurately display the geometry of the underground space Morphology, which can be widely used for probing. [0003] For the underground space detection technology, my country mainly uses drilling as the main method and geophysical prospecting as the supplement, and foreign countries mainly use geophysical prospecting. In recent years, electrical methods, electromagnetic methods, microgravity methods, and seismic methods have a relatively high level, but it is difficult to use these...
