Title:
MONOCULAR THREE-DIMENSIONAL SCANNING SYSTEM BASED THREE-DIMENSIONAL RECONSTRUCTION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/015154
Kind Code:
A1
Abstract:
Disclosed are a monocular three-dimensional scanning system based three-dimensional reconstruction method and apparatus. The monocular three-dimensional scanning system comprises an invisible structured-light scanning module, a camera and a projection device. The method comprises: using an invisible structured-light scanning module to collect a depth map of a detected object, and converting the depth map into a set of three-dimensional data points, wherein the set of three-dimensional data points comprises a plurality of three-dimensional points; determining a target light-plane equation corresponding to a target three-dimensional point of the plurality of three-dimensional points; projecting the target three-dimensional point to a modulated multi-line stripe image, and determining a target stripe, corresponding to the target light-plane equation, in the modulated multi-line stripe image; and according to the target light-plane equation and the centre coordinates of the target stripe, acquiring a three-dimensional point, reconstructed in a camera coordinate system, of the target stripe. The present invention solves the technical problem that blockage exists in three-dimensional reconstruction of binocular stereoscopic vision.
