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, w

Embodiment Construction

[0021] see figure 1 : is a structural schematic diagram of the device for real-time capture and adaptive fusion of infrared light images and visible light images of the present invention. The light from the target and its surroundings is first irradiated onto the illuminance meter 1 and the half-mirror 2 . The half mirror 2 has a size of 100×100 mm and a thickness of 1.1 mm. The half mirror 2 is installed on the lens position adjustment device 3 to form a light splitting system. The half mirror 2 reflects visible light and transmits infrared light. Visible light filter 4 is installed on the camera lens of first CCD5, and first CCD5 is positioned at the reflected light area of ​​half mirror 2, and is placed on front track 6. The first CCD5 receives the visible light reflected by the half mirror and filtered by the visible light filter 4 to form a visible light image. The infrared light filter 9 is installed on the lens of the second CCD10, and the second CCD10 is positioned...

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...
