Abstract

The invention is applicable to the technical field of electronics, and provides an optimal computation method of a rotating shaft in a three-dimensional (3D) scanning system. The method comprises the steps of obtaining an intersecting line of plane 3D data of multiple angles to serve as the initial rotating shaft of a rotating table, scanning a zero-angle 3D model, obtaining a first group of 3D data, controlling the rotating table to rotate a set angle, scanning and rotating a 3D model of the set angle, obtaining a second group of 3D data of the set angle, obtaining a coarse registration matrix through the set angle and the initial rotating shaft, computing a first optimal matrix through a fine-registration algorithm according to the first group of 3D data and the second group of 3D data of the set angle, scanning and rotating the 3D model, obtaining the 3D data of the set angle, computing a second optimal matrix, obtaining N optimal matrices, computing a registration error of each optimal matrix, and selecting the rotating shaft of the optimal matrix with the minimum registration error as the rotating shaft in the 3D scanning system. The optimal computation method has the advantage of computing the rotating shaft accurately.

Description

technical field [0001] The invention belongs to the field of electronics, and in particular relates to an optimization calculation method for a rotating shaft in a three-dimensional scanning system. Background technique [0002] Existing 3D scanning systems can only scan visible information on the surface within the scanning range. In order to obtain a complete 3D model of an object, it is usually necessary to move the scanner of the 3D scanning system, or rotate or move the scanned object to obtain a complete 3D model of the object. Complete the acquisition of three-dimensional information from different angles of the scanned object. Due to changes in the position of the scanner of the scanning system or the position of the scanned object, each scan data is limited to a different scanner coordinate system or a different scanned object coordinate system, resulting in the 3D data cannot be directly and orderly arranged into a within a unified coordinate system. In order to ...
