In order to realize geomagnetism aided navigation (GAN) in the regions with insignificant geomagnetic characteristic, inspired by the pattern recognition idea, the geomagnetic matching (GM) problem was transformed into statistical pattern recognition and was analyzed from the aspect of pattern recognition. A matching algorithm based on support vector machine (SVM) was proposed. The selection of training...
A new feature point matching method was proposed to improve the target recognition result. The feature points were chosen in the area that was evidently different with its peripheral region. The number of the feature points could be controlled by choosing appropriate threshold value. Three matching criterion function were defined according to the number of feature points in the template image and...
