Title:
PHOTOMETRIC STEREOSCOPIC THREE-DIMENSIONAL RECONSTRUCTION METHOD AND SPECTROPHOTOMETRIC STEREOSCOPIC CAMERA
Document Type and Number:
WIPO Patent Application WO/2018/176534
Kind Code:
A1
Abstract:
A photometric stereoscopic three-dimensional reconstruction method and a spectrophotometric stereoscopic camera, the method comprising: simultaneously projecting infrared light generated by three infrared light sources respectively to a target object; collecting light reflected by the target object by means of a lens to obtain a source optical path; extracting optical signals related to the three infrared light sources respectively from the source optical path to obtain three optical signals; converting the three optical signals into corresponding infrared image data respectively so as to obtain three groups of infrared image data; and utilizing the three groups of infrared image data to carry out a three-dimensional expansion reconstruction operation on the target object to obtain three-dimensional reconstruction data of the target object. With the present invention, the accuracy of subsequent three-dimensional reconstruction may be improved, and the quantity of lenses is just one, so that the difficulty brought on by synchronous adjustment of multiple lenses may be prevented, which aids a user in actual application operation.
