Real time shooting and self-adapting fusing device for infrared light image and visible light image

Abstract

The invention provides a device for real time taking and self-adaptive fusion of infrared light images and visible light images, relating to the detection and fusion of the image. A dichroic mirror is installed on a lens position adjusting device, and the dichroic mirror and the lens position adjusting device constitutes an optical splitting system which resolves a target and ambient lights thereof into visible lights and infrared lights; two CCDs with a visible light filter and an infrared light filter respectively obtain the visible light image and the infrared image of the target; a computer is connected with an image grabbing card by a communication line, a light intensity signal detected by an illuminance meter is input into the computer by a video grabbing card; and complete registration of the visible light image and the infrared image can be realized in a mechanical manner, thus realizing the real time taking and self-adaptive fusion of the infrared light image and the visible light image.

Description

Technical field: [0001] The invention relates to an image detection and fusion device, which can realize adaptive fusion of infrared light images and visible light images. Background technique: [0002] At present, the visible light camera system and the infrared light camera system adopt independent detection and display recording systems, and their front-end detectors are respectively visible light coupling device (CCD) and infrared focal plane detector. [0003] The working process of the above separated camera system is as follows: when the visible light camera system detects the target, the visible light detection system images the target to obtain a visible light image; when the infrared light camera system detects the target, the infrared light detection system detects the target Imaging is performed to obtain an infrared image. The computer implements signal processing, and performs fusion processing on the detected visible light image and infrared image to obtain a...

AI Technical Summary

Problems solved by technology

[0004] Since two independent detection devices are used to collect the same target, there are two problems in the captured target image: (1) there must be deviations in the position and detection angle of the two target images; (2) the current infrared The image specifications obtained by the focal plane detector are mainly 120×160 and 240×320, while the image size specification of the CCD is at least 640×480

This is an invention patent with limited applicability. At the same time, the registration method of visible light images and infrared images in this patent is relatively complicated, and the image fusion algorithm does not consider the influence of illumination, so it is not adaptive.
