| Abstract: | A method for comparison of 3D surfaces mutually displaced in space is developed. This method is based on the measure of distinction expressed by the volume between two optimally superimposed surfaces. The volume is determined from the height map calculated with respect to a specified plane. Pyramidal representation of height maps is used to reduce the amount of examination. In addition, the maps are calculated using graphic processors. This method can be used in the problem of superposition (and identification) of identically oriented, mutually displaced surfaces. |
