Image fusion method and apparatus using multi-spectral filter array sensor

摘要

Provided is an image fusion apparatus using a multi-spectral filter array sensor, the image fusion apparatus including a separation unit configured to separate an input image input through the multi-spectral filter array sensor into an RGB image and a near infrared (NIR) image, a color reconstruction unit configured to extract an RGB image in a visible band by removing an NIR value incident together with R, G and B values through the multi-spectral filter array sensor from the R, G and B values, and an image fusion unit configured to fuse the RGB image in the visible band with the NIR image, in which a fusion rate of the RGB image and the NIR image is based on a size of each of the R, G and B values of the RGB image in the visible band.

1. An image fusion apparatus using a multi-spectral filter array sensor, the image fusion apparatus comprising at least one processor to implement:
a separation unit configured to separate an input image input through the multi-spectral filter array sensor into an RGB image and a near infrared (NIR) image; a color reconstruction unit configured to extract an RGB image in a visible band by removing an NIR value incident together with R, G and B values through the multi-spectral filter array sensor from the R, G and B values; and an image fusion unit configured to fuse the RGB image in the visible band with the NIR image, in which a fusion rate of the RGB image and the NIR image is based on a size of each of the R, G and B values of the RGB image in the visible band, wherein respective color channels R′, G′, and B′ fused by the image fusion unit are given by:(R′G′B′)=(1+k0001+k0001+k)·(RGB),wherek=3⁢NR+G+B,and N indicates the NIR image.
