Problems solved by technology

[0003] The existing methods mainly include: 1) Use some pan-tilts to determine the position change relationship between the measured object and multiple viewpoints, and directly calculate the coordinate change relationship between the point cloud geometric data under multiple viewpoints through the motion parameters of the pan-tilt. The method is stable and reliable, and has high precision, but requir

Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0029] The current stitching method of 3D scanning point cloud geometry mostly uses multiple measurement markers to search and construct matching marker point pairs to obtain point cloud geometric data, and then realizes automatic stitching of multi-view point cloud geometric data by changing the coordinate relationship. The stitching process Complicated and time-consuming.

[0030] In order to solve the above technical problems, this application ...

Abstract

The invention provides a cloud point splicing method, terminal equipment and a computer storage medium. The point cloud splicing method comprises the following steps: acquiring two point clouds obtained by scanning around the same rotating shaft; based on the two point clouds, obtaining a rotation translation matrix through calculation; obtaining a direction vector of a rotating shaft based on therotation translation matrix, and acquiring rotation angles of other point clouds based on the two point clouds; acquiring rotation translation matrixes of the other point clouds and the two point clouds based on the direction vector and the rotation angles, performing rotation translation on the other point clouds according to the corresponding rotation translation matrixes; and splicing the point clouds after rotation translation. According to the cloud point splicing method, the rotation translation matrixes of the other point clouds are obtained through calculation according to the rotation axis obtained through the two point clouds, and the situation that the calculation amount of the rotation translation matrixes is directly calculated multiple times is avoided, and the point cloud splicing efficiency is effectively improved.
