Problems solved by technology

In practical applications, due to the manufacturing process, processing and adjustment of the laser radar scanning equipment itself, as well as the transportation vibration of the whole device (including various parts of the laser radar equipment), the center of the laser radar equipment will deviate from the design position, and for applications related to high-precision 3D data acquisition In terms of demand, the ranging error caused by the above equipment center deviation is unacceptable
[0004] In addition, there are many types of 3D laser scanners

Example Embodiment

[0015] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that in the drawings or description of the specification, similar or identical parts use the same drawing numbers. The implementations not shown or described in the drawings are those known to those of ordinary skill in the art. In addition, although this article may provide an example of a parameter containing a specific value, it should be understood that the parameter does not need to be exactly equal to the corresponding value, but can be approximated to the corresponding value within acceptable error tolerances or design constraints. The directional terms mentioned in the embodiments, such as "upper", "lower", "front", "rear", "left", "right", etc., are only directions with reference to the draw...

Abstract

The invention provides a single-linear-array laser radar equipment centering method. The method aims to solve the high-precision centering problem of laser radar equipment, a laser radar triangular reflection target is adopted and scanned and imaged for many times, and the centering problem of the laser radar equipment is changed into a problem of intersection of straight lines, so that the relevance between centering of the laser radar equipment and equipment work principles is lowered, the centering procedures of the laser radar equipment are simplified, and precision of centering and ranging evaluation of the laser radar equipment is improved.

Description

technical field [0001] The invention relates to the technical field of laser radar in the optoelectronic industry, in particular to a method for center calibration of single-line array laser radar equipment. Background technique [0002] With the further development of 3D laser scanning technology and the increasing demand for reverse engineering, mechanical manufacturing and high-resolution aerospace applications, the importance of high-precision calibration and ranging accuracy evaluation for LiDAR scanning equipment has become increasingly prominent. [0003] The high-precision calibration and ranging accuracy evaluation of laser radar equipment firstly confirms the precise position of the center of laser radar equipment. In practical applications, due to the manufacturing process, processing and adjustment of the laser radar scanning equipment itself, as well as the transportation vibration of the whole device (including various parts of the laser radar equipment), the c...
