Embodiment 1

[0026] refer to figure 1 , 5 , which is the first embodiment of the present invention, this embodiment provides a kind of coal yard stockpiling laser measurement device, which includes the object stockyard 102 to be measured, the stockyard 102 is generally arranged on both sides of the track 101, and the shape of the stockyard 102 is Indefinite; it also includes a laser measurement module 200 and a data processing module 300 , a vehicle body 201 is set on the track 101 , and both the laser measurement module 200 and the data processing module 300 are set on the vehicle body 201 .

[0027] Further, the laser measurement module 200 includes a cantilever 203 arranged on the vehicle body 201, and a laser scanner 204 is arranged on the cantilever 203. The laser scanner 204 includes a laser rangefinder and an angle sensor, and the laser rangefinder is used to obtain the measuring station. The distance to a measuring point is obtained by combining the angle sensor with two degrees o...

Embodiment 2

[0031] refer to Figure 1-2 , is the second embodiment of the present invention, which is based on the previous embodiment, wherein,

[0032] The cantilever 203 includes a first fixed arm 203a and a second fixed arm 203b. The turntable 202 is provided with a cylinder and the turntable 202 as a whole. The first fixed arm 203a and the second fixed arm 203b are all fixed on the cylinder. The arm 203a is inclined upwards, and the second fixed arm 203b is arranged downwards and connected with the first fixed arm 203a. The first fixed arm 203a, the second fixed arm 203b and the turntable 202 form a triangle. This structure is the most stable and can be mounted on Various components on it maintain the strength of the cantilever 203 . The first fixed arm 203a is provided with a sliding bar 203c to slide and connect with it. Through the sliding of the sliding bar 203c, the length is changed. The laser scanner 204 is installed on the sliding bar 203c, so the laser scanner 204 can be ad...

Abstract

The invention discloses a coal yard stockpile laser measuring device, which comprises a track, and stockpiles are arranged on the two sides of the track; the laser measurement module comprises a carrying vehicle body arranged on the track, a rotary table is arranged on the carrying vehicle body, a cantilever extends out of the rotary table, and a laser scanner is arranged on the cantilever; the data processing module comprises a control computer, a data transmission table, a stroke meter and a return meter which are arranged on the carrying vehicle body, and the data transmission table is connected with the user side; the adjustable cantilever is arranged on the rotary table, the positions of the laser scanners can be adjusted at any time, meanwhile, a plurality of laser scanners can be additionally arranged to meet the requirement that a three-dimensional model of a complete stock ground is difficult to obtain due to insufficient measurement angles, the positions of the scanners are controlled through the control computer, user requirements are met, operation is easy, and convenience and practicability are achieved.

Description

technical field [0001] The invention relates to the technical field of laser measurement, in particular to a laser measurement device for stockpiling in a coal yard. Background technique [0002] Use the laser rangefinder to obtain the distance from the measuring station to a certain measuring point, commonly known as dot, and combine the horizontal and vertical angle sensors with two degrees of freedom to obtain the two azimuth angles of the current observation point, and calculate the three-dimensional space coordinates of the measuring point. Use these measured points to perform three-dimensional calculations, build a grid, perform image rendering to generate a three-dimensional image, and calculate the cube, which is the principle of laser measurement. [0003] In the existing technology, due to the non-uniform shape of the stockyard, the installation position of the laser scanner is limited, resulting in an incomplete measurement area, the scanning angle of the scanner ...
