Problems solved by technology

[0004] The purpose of the present invention is to disclose a target detection system based on image fusion, which solves the problem in the prior art that fusion processing of images is performed using predetermined fusion weights, and the influence of light changes on visible light images is not considered. When it is poor, the image quality obtained by fusion is poor, which affects the accuracy of the subsequent target detection results.

Abstract

The invention discloses a target detection system based on image fusion, and the system comprises an obtaining module, a preprocessing module, an image fusion module, and a target detection module. The image fusion module is used for performing image fusion processing on the preprocessed infrared image and visible light image obtained by processing the infrared image and the visible light image by the preprocessing module to obtain a fused image, and the target detection module is used for judging whether a detection target exists in the fused image or not. When image fusion is carried out, the first intermediate image is obtained through the fusion weight obtained by constructing the covariance matrix, then the second intermediate image is obtained by considering the light change, and the fusion image is obtained based on the first intermediate image and the second intermediate image. Compared with a single visible light image or an infrared image, the quality of the obtained fused image is higher, and correct recognition of a detection target is facilitated.

Description

technical field [0001] The invention relates to the field of target detection, in particular to a target detection system based on image fusion. Background technique [0002] In the prior art, when a single type of image is used for target detection, the problem of inaccurate detection results often occurs. Infrared images can represent the amount of energy radiated by the target, but lack detailed information such as the outline and texture of the object, while visible light images can retain information such as outlines and textures when the light conditions are good. However, visible light images are easily affected by factors such as illumination. influences. Therefore, there is a method of fusing infrared images and visible light images, and then performing object detection on the fused images. [0003] In the existing fusion process of visible light image and infrared image, weighted fusion is generally used to fuse the two images. Image fusion, obviously, this sett...
