THREE-DIMENSIONAL RECONSTRUCTION METHOD, DEVICE, APPARATUS, AND STORAGE MEDIUM

WIPO Patent Application WO/2020/237492

A1

Provided are a three-dimensional reconstruction method, a device, an apparatus, and a storage medium. The method comprises: acquiring sets of first position coordinates corresponding to respective structured light patterns on an measurement image; determining, according to the measurement image, a first calibration pattern and a second calibration pattern, a calibration interval for the respective structured light patterns on the measurement image, wherein the first calibration pattern is a structured light calibration pattern calibrated on a first calibration plane, the second calibration pattern is a structured light calibration pattern calibrated on a second calibration plane, and the first calibration plane and the second calibration plane are parallel to a camera plane; performing calculation according to the calibration interval for the respective structured light patterns on the measurement image to obtain a depth value of each set of first position coordinates; and performing reconstruction of the measurement image according to the depth value of each set of first position coordinates and a calibrated reconstruction parameter. The invention enhances the efficiency of three-dimensional reconstruction.
