Document Type and Number:
WIPO Patent Application WO/2021/258276
Kind Code:
A1
Abstract:
A three-dimensional imaging method, comprising: obtaining a first image (1210) and a second image (1220) within a preset period of time, wherein the first image (1210) and the second image (1220) are collected after projection light having two-dimensional pattern information (1100) is projected onto an object, the maximum value region of the pixel value of the two-dimensional pattern information (1100) in the first image (1210) is a first region, the maximum value region of the pixel value of the two-dimensional pattern information (1100) in the second image (1220) is a second region, and the first region and the second region do not overlap with each other; determining a first feature image (1310) and a second feature image (1320) according to difference values of the pixel values of corresponding pixel points between the first image (1210) and the second image (1220); and determining the three-dimensional image (1400) of the object according to the first feature image (1310) and the second feature image (1320).
