High accuracy-automatic registration method research on multi-source remote sensing image
摘要
Abstract
In remote sensing image automatic registration,there are some problems,for example, there are differences between texture image itself and unevenness in feature points extracting.To this problem,the paper proposes a new high precision automatic registration method of multi-source re-mote sensing image.First of all,the Harris operator was improved to extract feature points covering a wider range;and then,the image is divided into blocks,using the improved Harris operator to ex-tract feature points for each block,and then use the block iteration to eliminate wrong feature points, ensuring the distribution of feature points is uniformly and non redundant in the whole image.Second-ly the paper put forward the pyramid-bidirectional-least squares matching algorithm for image matc-hing,completed selection of the final corresponding points.Finally,the paper made use of the TIN to complete accurately correction.The experimental results show that the proposed method of the paper can ensure the corresponding points uniform and reasonable,and it can achieve high precision registra-tion of multi-source remote sensing image,which has certain practical significance.关键词
