To generate a 3D computer model of a subject object 210, images 300-312 of the subject object are recorded from different viewing positions and directions. The image data is processed to calculate the positions and directions, and a 3D computer model of the surface shape of the subject object 210 is generated. A further image 330 of the subject object, which was not used in the processing to generate the 3D computer surface shape model but which shows a part of the subject object for which texture data is to be generated, such as the base of the subject object, is registered with the 3D computer surface shape model. The registration is carried out by displaying the further image to a user as a stationary image and providing a virtual camera for control by the user to view the 3D computer surface shape model. Images of the 3D computer surface shape model are generated and displayed overlaid on the stationary image in accordance with the virtual camera as it is moved by the user. In this way, the user can see both the 3D computer model and the underlying stationary image and can move the virtual camera to generate a view of the 3D computer model which corresponds to the view of the subject object shown in the stationary image. The imaging parameters of the virtual camera are then stored to define the imaging parameters of the further image. Texture data for the 3D computer model is then generated using the image data from the further image. <IMAGE> |
