Abstract

The invention discloses an infrared video image and visible light video image fusion method, system and device, and relates to the technical field of image fusion, and the method comprises the steps: carrying out the image enhancement of an infrared video image, and obtaining an edge-sharpened infrared video image; performing image registration on the infrared video image and the visible light video image after edge sharpening, performing anisotropic filtering processing on the infrared video image and the visible light video image after registration, and obtaining an infrared video image feature part and a non-feature part and a visible light video image feature part and a non-feature part; performing principal component analysis on the feature part and the non-feature part to obtain a feature part fusion image and a non-feature part fusion image; and fusing the feature part fusion image and the non-feature part fusion image to obtain a fused image. According to the method, the definition of the finally obtained fused image can be improved.

Description

technical field [0001] The present invention relates to the technical field of image fusion, in particular to a fusion method, system and device for infrared video images and visible light video images. Background technique [0002] Since the 21st century, night vision technology with single-band working mode has gradually failed to meet people's requirements for high-quality, multi-spectral information images. Therefore, research and development of multi-band sensors and multi-band image fusion technology have received more and more attention. At present, It has become an important research direction in the field of optical engineering. In the fusion of multi-spectral images, the fusion of infrared and visible light has the most research value and is the most widely used. Infrared and visible light fusion technology can be used not only in the military field, but also in social security monitoring, car night vision medical imaging, industrial control, traffic supervision a...

Problems solved by technology

[0004] At present, the infrared and visible light fusion devices on the market basically come from the exports of developed countries in Europe and the United States, which has caused problems such as many import restrictions, high costs, and expensive maintenance costs.

Although the infrared and visible light fusion devices on the market can achieve video image fusion, the cost is very high, and the camera is too bulky, which is inconvenient to use, and the resulting fused image is not clear enough.

Domestic research on image fusion technology often only studies on a single level, focusing on the research on image fusion algorithms, that is, most of the research only studies image algorithms, and does not focus on video implementation after the research, but only judges on several images, so it can be practically applied There are fewer high-quality infrared and visible light fusion devices
