Abstract:
1. A method of recording images of a subject object, processing the image data to generate data defining a three-dimensional computer model of the subject object, and rendering the three-dimensional computer model to generate an image thereof to show a predetermined part of the subject object, comprising: positioning the subject object relative to a calibration pattern so that a selected part of the subject object which is to appear in the image of the three-dimensional computer model is positioned in a predetermined direction relative to the calibration pattern; recording images of the subject object and calibration pattern from different relative recording positions and/or orientations; processing data defining the recorded images to calculate the relative positions and orientations at which the images were recorded by comparing the calibration pattern in the images with stored data defining the calibration pattern; generating data defining a three-dimensional computer model of the subject object relative to the stored calibration pattern using the calculated positions and orientations; and generating data defining an image of the three-dimensional computer model showing the selected part of the subject object using a viewing camera defined relative to the stored calibration pattern.
