Abstract

Single-channel triple-band color night vision system is able to gain low-light color imagery. The core design idea of one-channel triple-band color night vision system is increasing a scanner than traditional low-light night vision system in the front of the image intensifier. The scanner is consisted of several filters which is used for dividing the emitted light or reflected light of the aim into three parts, R, G and B. Each part is taken a frame image respectively and then fused three frames into color imagery by Color Mapping Guidelines. The addition of filters makes the SNR of each frame image decreases, it means that images detail loss and gray value is low. To overcome this difficult, on the basis of three frame images fusion, a frame image of all band is added to fusion. Experimental results show that fused image which is fused by R, G, B and all band improve image brightness and detail information obviously through calculating the variance and entropy. This fused method is more conducive to the human eye.
