THREE-DIMENSIONAL RECONSTRUCTION METHOD AND APPARATUS FOR TRANSPARENT OBJECT, COMPUTER DEVICE, AND STORAGE MEDIUM

WIPO Patent Application WO/2020/019245

A1

The present application relates to a three-dimensional reconstruction method and apparatus for a transparent object, a computer device, and a storage medium. The method comprises: obtaining contours and a light correspondence of a transparent object to be reconstructed in different observation angles, obtaining an initial transparent object model of the transparent object to be reconstructed, and filtering lights involving multi-refraction and total reflection in lights having the light correspondence by means of reverse light tracking; obtaining a surface normal vector and a Snell normal vector of the initial transparent object model in viewing angles of different photographing devices, and performing first optimization on the initial transparent object model according to the consistency between the two vectors to obtain a point cloud reconstruction model; obtaining a Poisson sampling point of the initial transparent object model, and updating the point cloud reconstruction model; performing second optimization on the updated point cloud reconstruction model according to the contour of the transparent object to be reconstructed and a projection of the updated point cloud reconstruction model; and performing three-dimensional reconstruction on the point cloud reconstruction model performed second optimization to obtain a three-dimensional model. The method can restore the complete surface of the initial transparent object.
