Abstract

The invention provides an image fusion method. The method comprises the steps of preprocessing an original image; performing feature point detection based on the preprocessed image; matching the images based on the feature points, and calculating the confidence coefficient of the matching combination between any two images; sorting all the image matching combinations based on the confidence coefficient, and storing the image matching combinations with high confidence coefficient in the same image set; performing camera parameter estimation on images in the image set; based on the camera parameter estimation, performing waveform correction and splicing on the images; and performing multi-band fusion based on the waveform correction and the spliced image, and performing illumination compensation on the fused output image. The fusion image obtained through the image fusion method is higher in robustness, better in precision and higher in calculation speed.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to an image fusion method. Background technique [0002] In recent years, the video surveillance system has become an indispensable management method for rail transit depots. Managers can grasp a large amount of on-site information without having to visit the site in person, which reduces the cost of manpower and material resources. The monitoring system can improve the effect of management and supervision, reduce the probability of accidents, and ensure the normal and stable operation of rail transit. [0003] However, the existing video surveillance system has shortcomings such as small video surveillance viewing angle and narrow field of view in key detection areas in terms of video fusion display, which cannot meet all monitoring needs. At present, some researchers introduce the sift method to solve the above problems in the existing video surveillance system. The sift method...
