Abstract

The invention provides an image processing method and device, and a three-dimensional scanning system. The method comprises the following steps: acquiring at least two groups of two-dimensional images obtained by shooting a target object by adopting at least two different exposure parameters; screening a plurality of images with normal exposure from the at least two groups of two-dimensional images; and performing three-dimensional reconstruction based on the connected regions of the plurality of images with normal exposure, and generating a three-dimensional image of the target object. A problem that the precision of the impressed three-dimensional data is affected due to unclear shot pictures caused by a single exposure parameter is solved.

Description

technical field

[0001] The present application relates to the technical field of three-dimensional scanning, in particular to an image processing method, device and three-dimensional scanning system. Background technique

[0002] With the development of computer technology and measurement technology, 3D laser scanning has also developed rapidly and has been applied in various fields, which has attracted more and more attention in the research field in China. Three-dimensional laser scanning is based on the principle of laser ranging. By recording the three-dimensional coordinates, reflectivity and texture of a large number of dense points on the surface of the measured object, it can quickly reconstruct the three-dimensional model of the measured object and the line, surface, and volume. and other image data. Since the 3D laser scanning system can intensively acquire a large number of data points of the target object, compared with the traditional single point measurement, ...
