Abstract
A three-dimensional (3D) reconstruction method is provided. The method includes obtaining a two-dimensional (2D) pixel coordinate of a pixel in a 2D image of an object and a direction of a ray; projecting the 2D pixel coordinate to a 3D space to obtain a plurality of 3D points on the ray; for each 3D point of the plurality of 3D points: predicting a signed distance value for the 3D point; predicting a validity probability for the 3D point; and predicting an intensity value for the 3D point; obtaining a rendering loss based on the predicted signed distance values, the validity probabilities, and the intensity values of the plurality of 3D points to update a 3D reconstruction network; and extracting a 3D model of the object based on the updated 3D reconstruction network.
