Fast wavelet fusion method of thermal imaging image and optical image of fast moving object

Abstract

The invention discloses a fast wavelet fusion method for fast moving object thermal imaging image and optical image, which includes preprocessing thermal imaging image and optical image, HSI decomposing thermal imaging image and optical image, wavelet decomposition processing, wavelet fusion processing and wavelet reconstruction processing to obtain fused image. As that thermal image and the optical image are HSI decomposed, The decomposition layers are fused by wavelet fusion method, which can effectively synthesize the thermal imaging image target characteristic information and optical imagescene details information, and obtain more comprehensive information fusion image, so as to realize the effective imaging of fast moving objects.

Description

technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a fast wavelet fusion method of thermal imaging images and optical images of fast moving objects. Background technique [0002] Due to the various limitations of the sensor's own physical characteristics, imaging mechanism, and viewing angle, a single image sensor is often unable to extract enough information from the scene, so that it is difficult or even impossible to obtain a comprehensive description of a scene independently. Thermal imaging images and visible light images are obtained through thermal imaging sensors and visible light imaging sensors respectively. Since the principles of the two sensors are different, their performances are also different. Thermal imaging images can better reflect the thermal target characteristics of the image, but are not sensitive to scene brightness changes, and the image clarity is low; visible light images can bette...
