Paper Abstract

In order to solve the problem of automatic target recognition in photogrammetry, a method of recognition for coded-pattern sequence by using image cross-correlation is presented. Coded-pattern sequences are a series of patterns that posses unique identification information, which will be extracted to realize recognition. The concrete operation is to do cross-correlation of the real pattern image and the fictitious templet image of every possible pattern. The basis of this method is the theory of signal processing that the operation of cross-correlation can detect the resemblance of signals with different offset. The result of experiment shows that this method is applicable in many situations and also has the characteristics of high accuracy and high speed.
