Image fusion equipment and method based on multi-spectrum, and image sensor

Abstract

The embodiment of the invention provides image fusion equipment and method based on multi-spectrum, and an image sensor. The image fusion equipment based on multi-spectrum comprises a light collectingdevice, an image processor, and an image sensor with five types of photosensitive channels; the five types of photosensitive channels comprise a RGB channel, an IR channel, and a W channel; the lightcollecting device collects target light corresponding to the incident light; the image sensor converts the target light into an image signal through the RGB channel, the IR channel and the W channel;the image processor analyzes the image signal into a RGB color signal and a brightness signal, and processes the RGB color signal and the brightness signal in a fusion way so as to obtain a fused image, wherein the combination of the channels in the analysis of the RGB color signal and the brightness signal contains five types of photosensitive channels. Through the image fusion equipment based on multi-spectrum provided by the invention, the problem that the image collection equipment for split light fusion in the prior art is complex in structure can be solved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to multispectral-based image fusion equipment, methods and image sensors. Background technique [0002] In low-illumination scenes, in order to ensure that the collected images cover more image information, an image acquisition device with spectroscopic fusion is usually required to collect images. Specifically, the basic principle of the image acquisition equipment for spectroscopic fusion is to 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 the fused image , wherein the fused image is a dual-band image, which reflects more image information than any of the single-band visible light image and infrared image. [0003] The image acquisition equipment for spectroscopic fusion in the prior art specifically includes: a ...

Problems solved by technology

[0004] Although the image acquisition equipment of spectroscopic fusion in the prior art can obtain the fused image, the optical system requires a special design to obtain infrared light and visible light at the same time, that is, to obtain infrared light and visible light at the same time through prism splitting and different optical sensors. The structure is more complex, which limits the scope of use
