Study of a new method for three-dimensional restoration from single image

摘要

The aim of three-dimensional recovery technology from the image is to recover the relative height of each point on the surface from the light variations in the single image and carry out the recovery. A new method that recovers three-dimensional is presented object based on radius basis function for the image from the unknown light source direction, which constructs a surface equation by the network, uses the reflectivity function as a constraint, continuonsly estimates the light source direction in the self-learning process of the network from the bright spots around the spread of the image, and eventually obtains a satisfactory surface equation. This method makes the resumption of surface good continuity and smoothness, and can recover the height value of each network point of the image and be automatically inserted in any point the among the network. It is suitable for the image of Lambert reflection model and the image of the Specular reflection model and the mixed-reflex model.
