The present application relates to methods and apparatuses for three-dimensional reconstruction of a transparent object, computer devices, and storage mediums. The method includes acquiring silhouettes and light correspondences of a to-be-reconstructed transparent object under different viewing directions, acquiring an initial rough transparent object model of the to-be-reconstructed transparent object, and filtering out light rays involved in multiple refractions and total reflections by backward ray tracing; acquiring surface normal vectors and Snell normal vectors of the initial rough transparent object model in camera device views, and performing a first optimization on the initial rough transparent object model by constraining consistency between the surface normal vectors and the Snell normal vectors of the initial rough transparent object model in the camera device views, and acquiring a point cloud reconstruction model; acquiring Poisson sample points of the initial rough transparent object model, and updating the point cloud reconstruction model according to the Poisson sample points.

Methods for three-dimensional reconstruction of transparent object, computer devices and storage mediums

The present disclosure relates to a system for acquiring a correspondence between light rays of a transparent object. The system includes a camera device, a display device, a turntable and a control device; the camera device, the display device and the turntable are electrically connected with the control device respectively; the turntable is configured to rotate a transparent object; the control device is configured to acquire images corresponding to display device in the first preset position, which are photographed by the camera device through the transparent object at different rotation angles, to obtain a primary image set; acquire images corresponding to the display device in the second preset position, which are photographed by the camera device through the transparent object at different rotation angles, to obtain a secondary image set; and obtain the correspondence between light rays of the transparent object from different viewing angles.
