Abstract

The invention discloses a three-dimensional reconstruction method and device based on a monocular three-dimensional scanning system. The monocular three-dimensional scanning system includes: an invisible structured light scanning module, a camera, and a projection device. The method includes: using the invisible structured light scanning module to collect a depth map of the measured object, and converting the depth map into a three-dimensional data point set , the three-dimensional data point set includes a plurality of three-dimensional points; determine the target light plane equation corresponding to the target three-dimensional point in the multiple three-dimensional points; project the target three-dimensional point onto the modulated multi-line fringe image, and determine the modulated multi-line The target fringe corresponding to the target light plane equation in the fringe image; according to the target light plane equation and the center coordinates of the target fringe, the reconstructed three-dimensional point of the target fringe in the camera coordinate system is obtained. The invention solves the technical problem of occlusion in the three-dimensional reconstruction of binocular stereo vision.

Description

technical field [0001] The invention relates to the field of three-dimensional scanning, in particular, to a three-dimensional reconstruction method and device based on a monocular three-dimensional scanning system. Background technique [0002] 3D digital technology is an emerging interdisciplinary field that has been actively researched internationally in recent years, and has been widely used in reverse engineering, cultural relics protection, industrial inspection and virtual reality. Handheld portable 3D scanners are widely used in the field of 3D scanning due to their convenience and flexibility. The principle of the existing handheld 3D scanner 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 projection speckle, simulated laser stripe of DLP projection, laser stripe, etc. . Among these structured light modes, the simulated laser stripes projected by DLP and the hand-...
