Abstract:
A process for the electronic recording of an image of the surface of an object, which image can be displayed as a function G(x, y), wherein x and y are the coordinates of a respective image point of the image and G designates its gray value, wherein the object is recorded sequentially over different times ti, where ti+1>ti, from different perspectives as function Gi in order to form the total image G from the individual images Gi(x, y) wherein portions are cut out of the individual images and joined together depending on the respective recorded view, comprising the steps of:determining a curved intersection line for defining the portions of every image aside from the first image Gi by comparison with the image content of the previously recorded or assembled image Giâˆ’1; the portion of the image Giâˆ’1 being defined by said curved intersection line and the corresponding portion of the image Gi being subsequently added to this intersection line to form the total image G (x, y); said intersection line being determined by forming a similarity function Gc(x, y) between the images Gi and Giâˆ’1, which similarity function Gc(x, y) is external with identical gray values at identical image point coordinates or also by including their surroundings; and said intersection line being formed by a curve y (x) which runs through at least one extreme with a very high similarity of the similarity function Gc(x, y); wherein an intersection line is determined for the curve y(x), wherein the sum of the values of the similarity function Gc(x, y(x)) over the curve y(x) is external with respect to the similarity.
