Abstract

The invention provides a visible light and infrared double wave band image fusion enhancing method. The visible light and infrared double wave band image fusion enhancing method includes the following steps: a) for the same target scene, utilizing a visible light sensor and an infrared detector to respectively acquire an original visible light image and an original infrared image; b) respectively preprocessing the acquired original visible light image and original infrared image; c) registering the preprocessed original visible light image and original infrared image so as to enable imaging fields of the visible light sensor and the infrared detector to be consistent; and d) utilizing a fusion method based on Laplace pyramid decomposition to perform image fusion on the registered images. The visible light and infrared double wave band image fusion enhancing method has the advantages of compensating the influence of lack of resolution of the detector on the visual quality of the output images, simplifying the image fusion rule, and greatly improving the fusion speed on the basis of guaranteeing the quality of the fused images.

Description

technical field [0001] The invention relates to the field of image fusion enhancement, in particular to an image fusion enhancement method based on dual bands of visible light and infrared, which is applied to a low-resolution handheld infrared thermal imaging device. Background technique [0002] With the development of sensor technology, the types of sensors used for imaging are increasing. Due to different factors such as imaging mechanism, working band and working environment, when different types of sensors image the same target or scene, the target or scene information obtained by them is different. For users, these differential information are often beneficial. Infrared detectors and CCD visible light sensors are the two most widely used imaging sensors. The infrared detector mainly performs imaging by receiving the infrared radiation radiated or reflected by the target in the scene. It has a certain degree of penetrating ability to the smoke, and it still has a goo...
