Stitching Technique for Reconstructed Thermal Images

For large-size spacecraft damage detection, the panoramic defect visualization image (PDVI) can be obtained by stitching the images of multiple IR detection results, taking into account the accuracy as well as efficiency of the detection. In order to achieve the above steps, in this chapter, the feature extraction technique of reconstructed thermal image will be introduced at first. The specific feature extraction and feature point description algorithm of reconstructed thermal image will be introduced in two perspectives of rapidity and fineness.
