Abstract
Images of a subject recorded from different viewing positions and directions are processed to calculate the positions and directions, and a 3D computer model of the subject is generated. A further image of the subject, not used in the processing to generate the computer model but showing a part of the subject for which texture data is to be generated, is registered with the computer model by displaying the further image as a stationary image and overlaying images of the computer model from a virtual camera moved by a user. The user sees both the computer model and the stationary image and moves the virtual camera to generate a view of the computer model which corresponds to that shown in the stationary image. The imaging parameters of the virtual camera are stored and texture data for the computer model is generated using the image data from the further image.
