Embodiment Construction
[0029] like Figure 1-Figure 5 As shown, the present invention discloses a method for splicing DR images, and the method comprises the following steps:
[0030] 1) Collect images: DR system collects images by means of upright photography;
[0031] 2) Image registration: First, the image data collected by the DR system is roughly registered at low resolution, and then the roughly registered image data is finely registered at high resolution;
[0032] 3) Image fusion: the image processed in step 2) is fused using a multi-band-based curve to eliminate ghosting in the image.
[0033] like figure 1 As shown, when the image is collected in step 1), the main optical axis of the ray of the DR system is perpendicular to the image plane, and the baseline during shooting is parallel to the image plane.
[0034] The image is taken repeatedly by the DR system, and the overlapping part of the image imaging is greater than one tenth of the distance from the ray source during the two shots...
