Embodiment Construction

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0022] In the process of image matching in the visible light band, although there will be a certain degree of radiation difference between images in different visible light bands, the radiation difference between the images is small. This type of radiation difference is often linear, and the commonly used methods such as normalization This type of radiation v...

Abstract

The invention discloses an image matching method, device, computer equipment, and computer-readable storage medium. The method includes: separately acquiring local area images of a reference image and an image to be matched; performing feature transformation on the local area images to obtain normalized Region image; perform feature point detection inside and outside the normalized region image to obtain feature points; match the feature points of the reference image and the image to be matched according to the feature points inside and outside the normalized region image to obtain the matching result ; Determine the matching result of the image to be matched and the reference image according to the matching result of the feature points. Through the implementation of the present invention, the deformation error caused by the angle and scale of the image in the image matching process is solved, and the extracted feature points can better cover the entire image, which greatly improves the viewing angle of large video data, and the imaging Efficiency and robustness of point set matching under complex environment and other practical problems.

Description

technical field [0001] The present invention relates to the technical field of image matching, in particular to an image matching method, device, computer equipment and computer-readable storage medium. Background technique [0002] Target matching is a key step in dynamic target tracking. In terms of feature types, there are currently two main types of matching methods: point features and line features. Target matching can be transformed into a feature point set matching problem of the target. The electronic fence video data around the island may have noise caused by complex on-site imaging environment, weather conditions, and atmospheric cloud interference, as well as outlier phenomena caused by factors such as illumination changes, viewing angle changes, or occlusions (that is, the obtained two sets of feature points Meetings are different), which seriously restrict the application efficiency of existing algorithms such as RANSAC (Nearest Neighbor Distance Ratio) when pr...
