Embodiment Construction

[0043] Specific embodiments of the present invention will be described in further detail below based on the accompanying drawings. It should be understood that the specific embodiments described here are only examples, and are not intended to limit the protection scope of the present invention.

[0044] Please refer to figure 1 , an embodiment of the present invention provides a three-dimensional scanning system for acquiring or collecting three-dimensional fringe point cloud data of the measured object 105 . The type of the 3D scanning system is not limited, including a fixed 3D scanning system and a handheld 3D scanning system. Preferably, the 3D scanning system is a handheld multi-stripe binocular 3D scanning system. It can be understood that when the 3D scanning system is a handheld multi-stripe binocular 3D scanning system, during the working process, images obtained at different time periods may have errors due to shaking.

[0045] The 3D scanning system includes a lig...

Abstract

The invention relates to a three-dimensional scanning system for acquiring three-dimensional fringe point cloud data of a measured object, which includes: a light source for alternately projecting a plurality of speckle patterns and fringe patterns successively on the measured object. The left and right cameras are used to synchronously collect left and right speckle images and left and right fringe images of the measured object. The speckle data and marker point data reconstruction module is used to obtain speckle three-dimensional data and marker point three-dimensional data according to the speckle image. The fringe matching module is used for back-projecting the left and right fringe images according to the speckle 3D data and the marker point 3D data and guiding the left and right fringe image stripes to match. The 3D reconstruction module is used to reconstruct the corresponding fringes matched with the left and right fringe images into 3D fringe point cloud data. The invention also provides a scanning method of the three-dimensional scanning system.

Description

technical field [0001] The invention relates to a three-dimensional scanning system and a scanning method, in particular to a three-dimensional digital imaging sensor for a hand-held multi-stripe three-dimensional scanning system, a three-dimensional scanning system and a scanning method. Background technique [0002] 3D digital technology is an emerging interdisciplinary field of active research in the world in recent years, and has been widely used in many fields such as reverse engineering, cultural relic protection, industrial inspection and virtual reality. Hand-held portable 3D scanners are widely used in the field of 3D scanning due to their convenience and flexibility. The principle of existing handheld 3D scanners is mainly based on the active stereo vision method of structured light. There are many modes of structured light, such as infrared laser speckle, DLP (Digital Light Processing) projected speckle, simulated laser stripes projected by DLP, Laser stripes, et...
