Embodiment Construction

[0047] Referring to Fig. 1, the present invention provides a radiation reprocessing method for DMC color composite images, which can effectively solve the problem of insufficient smooth color transitions in DMC color composite images, eliminate residual radiation differences, and significantly improve image quality. The present invention processes each color transition region in the DMC color composite image according to the following steps:

[0048] 1. Automatic positioning of color transition areas and stitching lines

[0049] a. Build an image pyramid:

[0050] In the DMC color synthetic image, for the rectangular area between every two adjacent CCD images, adopt the method of pixel averaging to establish 3-5 layers of pyramid image layers, such as adopting the method of 9 pixel averaging to establish a 4-layer pyramid ( Including the original image layer); the rectangular area between every two adjacent CCD images, when two adjacent CCD images are adjacent to the left and...

Abstract

This invention relates to DMC image response image radiation process method aiming at DMC color integration due to different cameral CCD difference in the image process and analysis field. This method adopts gold strategy and difference image fringe principle to automatically position matching lines and color area position and to adopt block method and voting to improve the method stability.

Description

technical field [0001] The invention belongs to the field of image processing and analysis, and relates to a radiation reprocessing method for DMC images. Background technique [0002] The application of aerial digital cameras makes it possible to use digital form from image storage to mapping. Compared with film cameras, it greatly reduces the cost, shortens the cycle of information processing, and improves the effectiveness of earth observation. , making it face unprecedented demands and broad application prospects. However, under limited flight control conditions, in order to meet the requirements of aerial photography overlap and obtain high-resolution images, due to technical limitations and cost considerations, it is still difficult to directly produce large-format area array CCD cameras. Some aerial digital cameras based on area array combination technology have emerged, such as Z / I Imaging's DMC (Digital Mapping Camera), which combines multiple small area array CCDs...
