I age fusion is a newly developing technology which extracts infor ation fro ultichannel i ages tofor a oreunderstandableoneforthe useof observer of decision aking syste . The laser assistant vision infrared i age is obtained byuseof infrared laser assistant vision technology. Thefeatures of LLL i age and laser assistant vision i age are different, becausethe spectru s they respond are different. The fusion of these two kinds of i age is realized based on contrast odulation using wavelet transfor . The experi ental results show that the fusion of laser assistant vision i age and LLL i age can effectively i prove the of quality i age. This technology can increase thewar field infor ati
