Abstract

Abstract

To estimate the attitude of the known 3D model space object from the mono-view image, a method is proposed by searching the local optimum of the correlation between the simulation image generated from Vega Prime and the observation image, which need not establish the relationships of target feature from 2D to 3D and abundant model matching library. Firstly, the input image is preprocessed to obtain the original target image. Secondly, Vega Prime program loads 3D model of the target, and generates a simulation matching image. The simulation image is preprocessed to obtain the matching target image. And the correlation of these two images is calculated. Finally, the attitude of model is updated until the correlation of the matching image and the original image is local optimum. Experimental results show that this method can estimate the attitude from the original simulation image accurately, and the average estimation error of the simulation observation image is 3.85°, which indicates that the proposed method is an effective method for space object attitude estimation.
