Abstract

The invention discloses a three-dimensional data splicing method, a three-dimensional scanning system and a handheld scanner. The method comprises the steps: acquiring a first image and a second image, wherein the first image and the second image are target images, acquired by a measurement module, of the surface of a measured object; performing three-dimensional reconstruction on the target image, obtaining a first point cloud based on the first image, and obtaining a second point cloud based on the second image; determining a splicing conversion relationship among the plurality of first point clouds; and splicing the plurality of corresponding second point clouds based on the splicing conversion relationship among the plurality of first point clouds. The technical problem that time and labor are wasted when point cloud data are spliced and scanned in real time through manual frequent point pasting in the prior art is solved.

Description

technical field [0001] The invention relates to the field of three-dimensional digitization, in particular to a three-dimensional data splicing method, a three-dimensional scanning system, and a hand-held scanner. Background technique [0002] In related technologies, the 3D scanning method based on the 3D reconstruction of fringe images requires manual pasting of points. By pasting landmarks or features on the surface of the object to be measured, photogrammetry is used to capture the landmarks and obtain their 3D data. After that, import the marker points or feature 3D data, and use the scanner to scan around the measured object using marker points or features. In order to ensure that the data can be unified into one coordinate system, it is necessary to use the marker points to scan the point cloud in real time. For splicing, it is necessary to manually clear the pasting points after scanning, which is a waste of time and manpower. [0003] For the above problems, no eff...
