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.

Reference mark, method for recognizing reference marks and method for object measuring

Described is a method of recognizing sequences of handwritten and/or joined-up numerals, in particular post codes, the method calling for the conversion of of feature vectors, thus enabling the sequence of numerals to be recognized using an HMM recognition device without the need for segmentation of the image. Also described are particularly relevant examples of feature extraction.
