Dense Euclidean reconstruction of 3D scenes is still a challenging task despite significant progress in the last 10 years. Data acquired underwater by a single, freely moving (handheld) camera is even more difficult to process, because of the lack of reliable salient points, wide and varying baselines between overlapping views, and water blurriness and wavelength-dependent light attenuation. Besides,...
This paper studies the problem of spatio-temporal matching between trajectories from two videos of the same scene. In real applications, trajectories are usually extracted independently in different videos. So possibly a lot of trajectories stay “alone” (have no corresponding trajectory in the other video). In this paper, we propose a novel matching algorithm which can not only find the existing correspondences...
Relative orientation is a very important step during photogrammetry. Traditional relative orientation is realized by adjusting the relative elements value, and eliminating vertical parallax of outstanding points on six standard point positions, or by analytical calculation after relative orientation with image point coordinates which are outstanding points on six standard point positions according...
