Abstract

The invention discloses an auxiliary device of point cloud registration of a three-dimensional scanner and a registration method of the auxiliary device. The auxiliary device comprises a cubic body and a magnetic base, wherein three planes, which are vertical to one another on the cubic body, comprise a first plane, a second plane and a third plane respectively; the magnetic base is fixedly connected with a fourth plane of the cubic body through a connection rod; the fourth plane is opposite to the second plane; and the magnetic base and a product are adsorbed together. With the adoption of the auxiliary device, a scanned part does not need to be scanned for the second time; however, the three planes of the cubic body with a relatively small size are scanned for the second time, and the efficiency can be improved by about 50%; a lug boss on the cubic body is used as a reference point for point cloud registration and the reference point can be easily found; the surface of the lug boss has a regular shape and point cloud data of the reference point are stable, so that errors of the point cloud registration are greatly reduced; and the auxiliary device disclosed by the invention is simple in structure, low in cost and convenient and rapid to operate.

Description

technical field [0001] The invention relates to the detection field, in particular to an auxiliary device for point cloud splicing of a three-dimensional scanner and a splicing method thereof. Background technique [0002] Three-dimensional scanning is a high-tech that integrates optical, mechanical, electrical and computer technologies. It is mainly used to scan the spatial shape and structure of objects to obtain the spatial coordinates of the object's surface. Its significance lies in the ability to convert the three-dimensional information of the object into a digital signal that can be directly processed by the computer, which provides a very convenient and quick means for the digitization of the object. [0003] As a fast three-dimensional measurement equipment, the three-dimensional scanner makes up for the existence of the three-coordinate measuring machine, which is easy to damage the probe, scratch the surface of the measured part, slow measurement speed, difficult...
