    • The invention relates to a method for the automatic, rapid segmentation of two-dimensional object surfaces from the three-dimensional depth data of objects which data are present in the form of a matrix-type data field. The inventive method is characterized by detecting the three-dimensional data field by scanning the objects line by line with a sensor in different measuring point areas and segmenting the two-dimensional object surfaces by determining the one-dimensional intersection of the measuring point areas with model object areas, determining a quantity of one-dimensional curves of intersection approximating the intersection, initialing an object area for every curve of intersection of the first measuring point line, determining, for every single subsequent measuring point line, the extent of consistency with the already initialed object areas and linking the curve of intersection with an object area, if said curve of intersection is consistent with the object area, or initialing a further object area if it is not consistent, or linking a plurality of object areas to give a single object area, if the one-dimensional curve of intersection is consistent with several object areas, and linking the one-dimensional curve of intersection with the linked object area.
