Simple laser scanning device

Abstract

The invention discloses a simple laser scanning device. The device comprises a circular tabulate base with 360-degree circumferential azimuth scales, a universal level, a column, an azimuth pointer, a sliding bar, a guide bar, a guide groove, a protractor and a laser range finder. Azimuths and dip angles of measuring lines are changed by rotating the column and moving the sliding bard, distances between different positions of an object to be measured and a laser point can be scanned and determined, and three-dimensional coordinates of the measurement points can be determined according to geometrical relationships to obtain surface spatial form coordinates of the object to be measured, accordingly, a three-dimensional form model of the object to be measured is established, and spatial form three-dimensional laser scanning and engineering deformation measurement, monitoring and scanning are performed on chambers, tunnels, cavities, goafs and the like in all directions without contacting with or disturbance to structure or engineering entities. The device is simple to operate, low in cost, convenient to carry and capable of being popularized, greatly optimizing and reducing data acquisition density and preventing later cumbersome processing of mass data.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional laser scanning, and in particular relates to a simple device for three-dimensional laser scanning of the spatial forms of chambers, roadways, chambers, goafs and the like. Background technique [0002] With the continuous development of information science and technology, three-dimensional simulation, physical reconstruction, virtual reality and other theories have been put forward one after another. People's understanding of things has gradually shifted from a flat two-dimensional space to a three-dimensional three-dimensional thinking mode. As a new technology for spatial information acquisition, 3D laser scanning technology realizes high-precision, high-speed, continuous and automatic 3D data acquisition of observation targets, overcomes the limitations of traditional measuring instruments, and becomes a direct acquisition target of high-precision 3D data. However, the high price of e...
