SpletIn global stereo vision, balancing the matching efficiency and computing accuracy seems to be impossible because they contradict each other. In the case of a long baseline, this contradiction becomes more prominent. In order to solve this difficult problem, this paper proposes a novel idea to improve both the efficiency and accuracy in global stereo … SpletShort stereo baseline retro-reflector detection method roceedings of the Irish Machine Vision and Image Processing (IMVIP) Conference, Dublin City University, Dublin, Ireland 2010 Other authors.

SpletShort Baseline (SBL) Systems: Short baseline systems use a baseline consisting of three or more individual sonar transducers that are connected by wire to a central control box. Accuracy depends on transducer spacing and mounting method. When a wider spacing is employed as when working SpletAbstract—Stereo visual odometry has received little investigation in high altitude applications due to the generally poor performance of rigid stereo rigs at extremely small baseline-to-depth ratios. Without additional sensing, metric scale is considered lost and odometry is seen as effective only for monocular perspectives. spin class newport beach

In this paper, we propose a method to ﬁnd a rela-tively sparse set of feature correspondences between wide baseline images. These initial matches yield the epipolar geometry and thus greatly facilitate the search for further correspondences. The initial features need
