Problems solved by technology

[0006] The function of the 3D laser scanner in the prior art is to obtain point cloud data. In the working process: first perform vertical line scanning, then rotate horizontally according to the set horizontal angular resolution, and then perform vertical line scanning. Although the process is very regular, there are technical defects such as scattered point clouds and large modeling errors

Embodiment 1

[0069] Embodiment one, as figure 2 As shown, the method of three-dimensional laser reciprocating scanning is: start from point A on the left side of the object and scan straight to the right, scan to point B on the right, then scan downward for a certain distance, and then scan in a straight line to the left. After arriving at point C on the left, scan a distance in a straight line downwards, and repeat this cycle until the specified position is scanned to obtain the corresponding point cloud data.

Embodiment 2

[0070] Embodiment two, such as image 3 As shown, the method of three-dimensional laser reciprocating scanning is as follows: start from point A on the left side of the object to scan from the upper right line to the arc segment, scan to point B on the right side, and then scan a certain distance to the lower left arc segment , and then scan in a straight line to the left. After scanning to point C on the left, scan a certain distance to the lower left arc segment, scan to point D on the left, and then scan in a straight line to the arc segment at the lower right Go to the point E on the right, and then scan a distance to the lower left arc segment, and then scan the arc segment to the upper left straight line to arc segment transition, scan to the left point F, and then scan to the lower right arc segment Point G on the right side, then scan to point H on the left side of the arc segment at the lower left, and then scan a certain distance to the lower right, and so on, until ...

Embodiment 3

[0071] Embodiment three, as Figure 4 As shown, the method of three-dimensional laser reciprocating scanning is: start from point A on the left side of the object and scan straight to the right, scan to point B on the right side, and then scan diagonally downward to the left, and scan to point C on the left side , and so on, until the specified position is scanned and the corresponding point cloud data is obtained.

Abstract

The invention discloses a three-dimensional laser scanning method controlled by a computer. The method comprises the following operation steps of A) preliminarily positioning an upper computer controlsystem; B) performing instruction interaction between the upper computer control system and a lower computer control system; 2, using the lower computer control system to feed back the control instruction execution information to the upper computer control system; C), carrying out preliminary data acquisition through the upper computer control system; D) carrying out data acquisition and uploading through the lower computer control system; e) adjusting the position of the upper computer control system; f) acquiring the data of the upper computer control system; and G) repeating the steps E)-F) until the completion. According to the method, the smooth point cloud data is obtained, the modeling errors are reduced, the construction speed and efficiency are improved, the construction environment and the construction refinement are improved, the construction quality is greatly improved, and the method has the good economic benefits and social benefits through popularization and application.

Description

technical field [0001] The invention belongs to the technical fields of mechanical manufacturing, intelligent control, and surveying and mapping, and in particular relates to a computer-controlled three-dimensional laser scanning method. Background technique [0002] At present, the intelligent machinery and automation industry is blooming everywhere in the field of technical machinery manufacturing and intelligent control, and promotes a new process quality management, which has a positive impact on the construction process and construction personnel. Manufacturers and plant engineers are working closely together to continuously find new, highly efficient automation solutions for the most demanding manufacturing processes that were previously considered non-automable, to meet the most demanding construction procedures that were previously considered unautomable. [0003] The existing machinery is manually controlled. In high-risk environments such as tunnels, there are disa...
