The acquisition of three-dimensional images (depth-images) of two-dimensional digital image data is done by arranging the optical system in such a way, that their optical axes are located so closely, that areas of the measured space, which are depicted by corresponding pixels, partly overlap in the entire measuring space. The depth-information is gained by analysing the differences of intensities of corresponding pixels. Hence it is possible to produce depth- information in to the number of pixels linear time, which enables real-time applications. Solving the correspondency problem, which is typical for stereoscopic methods, is not necessary and occlusion problems do not occur. |
