Application of Image Mosaic Algorithm in Lateral Multi-lens Video Logging

The wall sequence images acquired by lateral multi-lens video logging method had some peculiarities that the overlap region of adjacent images can be estimated. This paper proposed an image mosaic algorithm which first estimated the overlap areas of adjacent images, and then matched for the areas with SIFT feature matching algorithm. To achieve seamless image stitching, the gradated in-and-out linear fusion algorithm had been adopted to match overlap images. The experiments showed that this method can rapidly and accurately extract the corresponding adjacent image matching points, acquire the panoramic mosaic image of the lateral multi-lens video logging, and lay a foundation for the logging results analysis in the next stage.
