Abstract

The present invention discloses a panorama stitching brightness equalization method and system. The method comprises: by acquiring multiple paths of input images used for stitching a panorama, calculating a brightness mean value and a brightness difference value, which respectively correspond to overlap regions of each path of input image and two adjacent paths of input images stitched to both sides of the input image; according to the brightness mean value and the brightness difference value, which respectively correspond to the overlap regions at both the sides of each path of input image, and respectively corresponding positions of the overlap regions at both the sides on each path of input image, calculating brightness correction values that respectively correspond to both the sides of each path of input image; and according to the brightness correction values respectively corresponding to both the sides of each path of input image and a position corresponding to each pixel point on each path of input image, carrying out correction on a brightness value of each pixel point on each path of input image. According to the method and the system, each path of input image can be stitched and fused into the panorama with excellent overall brightness and natural transition under the non-uniform illumination condition; and the brightness integrity and consistency of the panorama are improved, and great convenience is brought to users.

Description

technical field [0001] The present invention relates to the technical field of panorama mosaic, in particular to a method and system for panorama mosaic brightness equalization. Background technique [0002] At present, the panoramic images of most panoramic stitching systems are only image stitching, that is, the collected images are stitched and fused into a panoramic image after certain processing, but there are still obvious stitching between each component, especially the boundary area. There are obvious gaps between images from different sources. Under non-uniform lighting conditions, there are problems such as poor brightness integrity of each part and strong unnatural transition. In a non-uniform lighting environment, the multi-channel input image capture system often has obvious differences in the brightness of each image. In this case, the splicing and fusion of panoramas will lead to obvious differences in regional brightness, which will affect the effect of pano...
