Embodiment Construction

[0088] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings, but it is not limited thereto. Any modification or equivalent replacement of the technical solution of the present invention without departing from the spirit and scope of the technical solution of the present invention should be covered by the present invention. within the scope of protection.

[0089] The invention provides a method for fusion of low-light and infrared night vision images, such as figure 1 shown, including the following steps:

[0090] S1. For the same target scene, collect the original low-light image and the original infrared image respectively.

[0091] Aiming at the same target scene, the present invention uses the low-light night vision system to collect the original low-light image and the infrared thermal imaging system to collect the original infrared image respectively. Among them, the low-light night vision system ...

Abstract

Disclosed in the invention is a low-light and infrared night vision image fusion method. The method comprises: step one, for one same target scene, collecting an original low-light image and an original infrared image respectively; step two, carrying out de-noising processing on the collected original low-light and infrared images; step three, carrying out effective and precise registering on the low-light and infrared images after de-noising by using an edge-feature-based image registration method; and step four, carrying out image fusion on the registered image by using a wavelet transform method. According to the invention, the low-light night-vision image and the infrared night-vision image are fused and advantages of the two images can be fully realized; and the multifunctional advantage of the night-vision system is increased, so that the observer can obtain accurate, comprehensive and reliable image information of a certain scene. Therefore, with the method, a fused image with a super high quality can be obtained and the fusion speed is fast.

Description

technical field [0001] The invention belongs to the technical field of image processing, and relates to an image registration and image fusion technology, in particular to a method for fusion of low light and infrared night vision images. Background technique [0002] The advantage of the low-light night vision device is that the visual experience is close to visible light, and it can well identify objects with different reflectivity for visible light. It is greatly affected by climate and environmental conditions, and the viewing distance is relatively short; the advantage of infrared thermal imager is that it is very sensitive to temperature, can detect temperature difference targets well, has a long detection distance, has the ability to penetrate smoke, and can identify camouflage The ability is strong, but the disadvantage is that the image layering is not strong, and it is difficult to recognize the scene targets with very close temperatures. Fusion of low-light and i...
