The invention relates to a reference mark, a method for recognizing reference
marks and a method for object measuring. According to the invention, the object
is fitted with coded reference marks. Said marks are automatically recognized and
decoded by the inventive method for reference mark recognition, whereupon a three-dimensional
representation of the object is realized. According to the invention, the method
compensates automatically for geometrical and radiometric interferences and generates
at least one quality measurement to evaluate the quality of recognition and decoding.
The invention particularly enables fast recognition and decoding of large numbers
of reference marks and fast measuring of objects.
