Image fusion equipment and image fusion method

Abstract

The embodiment of the invention provides image fusion equipment and an image fusion method. The image fusion equipment comprises a light acquisition device, an image processor and an image sensor witha red, green and blue RGB channel and an infrared IR channel; the light acquisition device blocks the spectrum of a first predetermined wavelength interval in incident light to obtain target light; the first predetermined wavelength interval is that a response difference of the RGB channel and the IR channel in the image sensor on an infrared band is higher than a wavelength range of the spectrumof a first predetermined threshold; the image sensor converts the target light into an image signal through the RGB channel and the IR channel; and the image processor parses the image signal into acolor signal and a luminance signal that is sensitive to the infrared band, and fuses the color signal and the luminance signal to obtain a fused image. According to the scheme of the invention, the operation of removing infrared components from the color signal by the image processor can be simplified, and the fusion efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image fusion device and an image fusion method. Background technique [0002] In a low-illumination scene, in order to ensure that the collected image covers more image information, an image collection device of spectral fusion is usually required to collect the image. Specifically, the basic principle of image acquisition by the image acquisition device of spectroscopic fusion is: collect the visible light image corresponding to the visible light signal and the infrared image corresponding to the infrared light signal, and fuse the visible light image and the infrared image to obtain a fused image. , wherein the fused image is a dual-band image, which reflects more image information than either the single-band visible light image or the infrared image. [0003] The spectroscopic fusion image acquisition device in the prior art specifically includes: a half mirror, a...

Problems solved by technology

[0004]Although the image acquisition equipment for spectroscopic fusion in the prior art can obtain the fused image, since the visible light image will be doped with infrared components, the image processor will When a visible light image is received, the calculation of removing the infrared component from the visible light image (ie color signal) is relatively large, resulting in low fusion efficiency
