Problems solved by technology

[0005] 1. Unable to achieve high-torque ultra-low speed (1 to 5 minutes to 1 revolution) stable and high-precision transmission;
[0006] 2. Quick start or stop will cause vibration;
[0007] 3. Due to the unstable transmission, the point cloud will be distorted irregularly, resulting in inaccurate data and large errors

Embodiment 1

[0033] A three-dimensional laser volume measurement device using worm gear transmission, the number of worm gears is 4, and the number of worm gears is 200;

[0034] Transmission ratio i=speed of worm (n1) / speed of worm wheel (n2)=number of teeth of worm wheel (n2) / number of heads of worm (n1);

[0035] Transmission ratio i=200 / 4=50;

[0036] 50=n1 / n2;

[0037] 50n2=n1;

[0038] The speed of the stepper motor is controlled by the instructions of the main board to drive the worm 50 revolutions per minute through the coupling, so that the worm gear can drive the shaft and the base to 1 revolution per minute, and finally realize the low-speed transmission of the laser measurement module. The measured point cloud image is as follows: image 3 shown.

Abstract

The invention discloses a device for achieving three-dimensional laser volume measurement by a worm wheel and worm transmission mode. The device comprises a fixed shaft, a transmission assembly and alaser assembly, wherein the device rotates around the fixed shaft through the transmission assembly to drive the laser assembly to rotate to measure the volume; and the transmission assembly comprisesa worm wheel and a worm. The device has the characteristics of great torque, steady ultralow speed and high-precision transmission, solves the technical problem that the measuring error is great as aresult of shake and unstable transmission caused by quick start or stop, and is simple to mount and relatively low in cost.

Description

technical field [0001] The invention relates to the field of port laser volume measurement, in particular to a device for realizing three-dimensional laser volume measurement by using a worm gear transmission mode. Background technique [0002] Three-dimensional laser scanning technology, also known as "real scene replication technology", overcomes the limitations of traditional measuring instruments with its advantages of non-contact, fast scanning speed, large amount of information, high precision, strong real-time performance, full automation, and complex environment measurement. , has become an important means to directly obtain target high-precision 3D data and realize 3D visualization. [0003] Using a 3D laser scanner to scan large-area accumulations (such as coal piles, soil piles, ore piles, garbage piles, etc.), can quickly obtain the 3D coordinates of a large number of surface points, so that the surface fluctuations of the measured object can be accurately repres...
