Abstract:
1. A system for generating a 3D depth profile of an object, the system comprising: a moveable video camera configured to continually capture 2D image data of said object as said camera is moved, said image data being captured as a plurality of 2D image frames where each frame comprises a plurality of pixels; a processor configured: to receive said 2D image data; to determine the position of the camera for each frame captured; to calculate the depth of the part of an object shown in a pixel in a first frame, said depth being determined with respect to a reference, said depth being determined by identifying said part of the object in at least one further frame and calculating the depth using the camera positions of said first frame and said at least one further frame, where x t is a t th point, Z is the depth, π is the weighting, a and b are parameters of a beta distribution and μ and σ 2 are the mean and standard deviation of said unimodal distribution; and to determine a depth profile of said object, the depth profile being determined for a plurality of parts of the object shown in said pixels, the system further comprises a display configured to display said depth profile and an indication in real time as data is still being gathered, the parts of the object for which the depth profile has been calculated.
