Abstract

A laser 3D visual high-precision three-dimensional calibration solid model is characterized in that the laser 3D visual high-precision three-dimensional calibration solid model comprises a body with afeature selection area and a plurality of identification cylinders which are arranged at corners of the body and are provided with triangular identification holes. The beneficial effects of the laser3D visual high-precision three-dimensional calibration solid model are data accuracy: compared with a 2D scheme, the unique height direction data of laser 3D is an essential advantage, and the calibration model is researched and developed for laser 3D vision, not only conforms to height 3D vision height data, but also conforms to a laser 3D calculation mode, and the uniqueness in the direction and the comprehensiveness of (x, y, z, rx, ry, rz) three-dimensional six coordinates are added, so that the calibration model plays an irreplaceable role in high-precision calculation of a three-dimensional algorithm; and splicing calculation can be carried out only by scanning four sides of the calibration model for four times by using a laser 3D camera. No complex contour is needed, and no complexmachining process is needed.

Description

technical field [0001] The invention relates to the field of camera calibration, in particular to a laser 3D vision high-precision three-dimensional calibration entity model. Background technique [0002] The current calibration technology generally uses a 2D method for camera position calibration and image splicing calibration, but the outline of the object exists in a three-dimensional form, so it is not enough to calculate the accuracy of the measured object if it is calibrated at the 2D level. s position. In addition, there are manufacturing tolerances between parts and parts, and between products. Therefore, 2D technology has inherent defects in calibration, splicing and positioning technology, and its fault tolerance rate is low, so it cannot truly realize intelligence. Contents of the invention [0003] In order to effectively solve the above problems, the present invention provides a laser 3D vision high-precision three-dimensional calibration solid model. [00...
