Abstract

The work presented in this paper concerns visual-based relative navigation of autonomous vehicles for satellite service. An evolutionary-based algorithm for the problem of pose estimation of 3D objects using 2D images is presented. The procedure consists on looking for six position parameters, three for rotation and three for translation, such that the projection of a model best fits a set of points (vertices) extracted from a 2D image. Distinguishing feature of the proposed algorithm is that the best matching model is also looked for. This feature is used for visual inspection in order to detect macro defects. A population of candidate solutions is used, whose goodness is measured in terms of distance between model and image points. Key features of the algorithm are also speed and robustness with respect to noise on the input data. Experimental results conducted both on synthetic and real images demonstrate the effectiveness of the proposed approach.
