Image processing system, three-dimensional shape estimation system, image generation system and object position and orientation estimation system

摘要

Check it in advance the initial values ​​of the parameters of the lighting conditions, the user without any, or manually entered to be able to handle images. A general-purpose illumination base model generation means 300, the position and orientation initial value input means 102, a face model generation means 103, and illumination base model calculation means 301, a perspective transformation unit 202, the image processing system, and illumination correction means 203, I and a parameter updating unit 204. General-purpose illumination base model generation means 300, should calculate the general-purpose illumination base model in advance. The face model generation means 103 generates a texture and the individual three-dimensional shape from a generic 3D face model. Also, illumination basis model calculation means 301 generates an individual illumination basis from the general illumination base model using the same parameters. The parameter updating unit 204 searches a shape error when reproducing the input image is minimum, the parameters of position and orientation, and texture.
