Abstract: In this paper, we use scanning laser imaging radar to acquire test data and achieve three-dimensional imaging process to laser data, giving data fusion method based on target features between laser radar image and passive optical image, and realizing three-dimensional fusion between laser image and optical image. The test results show that the fusion method of different image qualities based on target features proposed in this paper is feasible. The fused image has both rich spectral and three-dimensional informations.
