Abstract:
1. A method of recording images of a subject object from different positions and orientations and processing the recorded image data to generate a three-dimensional computer model of the subject object, said method comprising the steps of: supporting the subject object above a calibration object having a predetermined pattern of features using an object support having a known height; recording at different positions and orientations a plurality of images of the subject object supported above the calibration object; processing the recorded image data to calculate the position and orientation at which each of at least some of the images were recorded; and generating, using the calculated positions and orientations, data defining a three-dimensional computer model of the subject object by defining a volume of voxels in a three-dimensional space in dependence upon the known height of the object support such that the object support, but not the subject object, is excluded from the volume, and removing voxels from the volume in dependence upon the image data.
