A fusion method and a fusion system of high dynamic range images

The invention relates to a fusion method and a fusion system of high dynamic range images. The method comprises the following steps of: performing target detection on each LDR image in a low dynamic range image sequence to obtain an initial detection frame, expanding the initial detection frame according to a preset proportion, extracting a region to be segmented in an alternative detection framefrom the LDR image, and segmenting the region to be segmented to obtain a segmented target; The moving state of the segmented object is judged, and the moving object is merged into a background imageto obtain the segmented image of the moving object. Pixel clustering is performed on the LDR image with the highest exposure quality, a super pixel segmentation image is acquired, and the moving object segmentation image and each LDR image are weighted and fused according to the number of pixels of each super pixel mapped on the moving object in the moving object segmentation image to obtain a high dynamic range image.
