Abstract

The present invention provides a three-spectral image intelligent fusion method based on the bilateral filtering pyramid. The method comprises the following steps: firstly, setting up a three-spectralcamera by using a parallel optical axis, so that the three-spectral camera performs video signal collection on the same scene; performing displacement deviation and rotation distortion correction onthe collected three-way video signal; and performing pyramid chromatography processing on the bilateral filter, and after pyramid chromatography processing is completed, requiring the three kinds of pyramid information obtained by the three spectral images to be fused. According to the method provided by the present invention, the bilateral filter and the pyramid chromatography algorithm are effectively fused into a new and effective overall algorithm, the original three-spectral image is fused into a fused image containing all the features of the three spectra, and the fused image is output outward, so that the user only needs to observe the image to complete the acquisition of all the target features in the scene, and the observation efficiency and the user use convenience are greatly improved.

Description

technical field [0001] The invention relates to the technical field of intelligent detection imaging and image processing, in particular to an intelligent three-light image fusion method based on a bilateral filtering pyramid. Background technique [0002] At present, cameras with different bands are widely used in the application fields related to industrial machine vision, such as community security, industrial production, fire safety, forest fire prevention, security inspection and explosion protection, both internationally and domestically, to monitor the scene and the targets in it. Since the target features in nature can show different spectral features, the use of a single camera to complete the monitoring process of the scene and the target has been unable to meet the technical requirements of modern military and civilian use. The current existing solution is to use multiple cameras with different bands to observe the scene at the same time, such as using a visible l...
