Precision analysis of correlation coefficient matching for high-overlap images matching

With the development of low-altitude remote sensing technology,aerial images with high-overlap is becoming easy to obtain.At the same time,it will be more and more difficult to tackle the matching work.According to the correlation coefficient image matching method,the impact of area and threshold on image matching for high-overlap images was analyzed.Experimental results show that selecting the appropriate search area and threshold can improve the image matching results,and it can also improve the process of identifying the same name point and enhance the precision of 3-D model.
