Luminosity stereo three-dimensional reconstruction method and spectrophotometric stereo camera

Abstract

The invention discloses a luminosity stereo three-dimensional reconstruction method and a spectrophotometric stereo camera. The luminosity stereo three-dimensional reconstruction method comprises the following steps: simultaneously projecting respective infrared light generated by three infrared light sources to a target object; collecting light reflected by the target object through a lens to obtain a source optical path; extracting optical signals related to the three infrared light sources from the source optical path separately to obtain three-path optical signals; converting the three-path optical signals to corresponding infrared image data respectively to obtain three groups of infrared image data; and utilizing the three groups of infrared image data to carry out three-dimensional reconstruction operation on the target object to obtain three-dimensional reconstruction data of the target object. According to the luminosity stereo three-dimensional reconstruction method and the spectrophotometric stereo camera, the accuracy of subsequent three-dimensional reconstruction can be improved; and in addition, the amount of the lens is only one, so that the difficulty brought by synchronous regulation of multiple lenses can be prevented, and actual application operation of a user is convenient.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a photometric stereo three-dimensional reconstruction method and a spectroscopic photometric stereo camera. Background technique [0002] At present, more and more fields require 3D reconstruction of space objects to obtain 3D model information of space objects. The existing 3D reconstruction technology has been widely used in 3D printing, reverse engineering, cultural relic protection, medical plastic surgery, 3D human Face recognition, virtual wear, entertainment and many other fields have greatly facilitated people's daily work and life. [0003] In the existing photometric stereoscopic 3D reconstruction technology, people usually use the following method to perform 3D reconstruction of the target object: first turn on the first light source at a certain moment in order to collect the image of the target object corresponding to the first light source, and then turn on ...

Problems solved by technology

[0004] However, in the above-mentioned 3D reconstruction process, since the images of the target object collected at different times are not images of the same object state, the subsequent 3D reconstruction accuracy is reduced.
