Title: LIGHT-SPLITTING COMBINED IMAGE COLLECTION DEVICE
Abstract:
Disclosed is a light-splitting combined image collection device. In the image collection device, a light-splitting unit decomposes incident light into a visible light signal and a non-visible light signal; a visible light signal imaging unit, according to the visible light signal decomposed by the light-splitting unit, performs photosensitive imaging, forming a first visible light image; a non-visible light signal imaging unit, according to the non-visible light signal decomposed by the light-splitting unit, performs photosensitive imaging, forming a first non-visible light image; a rectification unit rectifies positions of the first visible light image and the first non-visible light image, obtaining a target visible light image and a second non-visible light image; a pre-processing synthesis unit adjusts the luminance of the second non-visible light image, obtaining a target non-visible light image; and a combining unit performs image combination of the target visible light image and the target non-visible light image, obtaining a combined image. The present solution can effectively guarantee the accuracy of colours of the combined image.
