Accurate and Computationally-inexpensive Recovery of Ego-Motion using Optical Flow and Range Flow with Extended Temporal Support

Abstract: The ego-motion of a moving RGB-Z sensor is computed using combined range flow and optical flow pixel constraints. The emphasis of the work is on computationally cheap yet accurate estimation of inter-frame translation and rotation parameters using a linear small rotation model. To ensure accurate inter-frame motion estimates, an iterative form of the estimator is developed which repeatedly warps the target frame and measures its misalignment with the current frame. As these motion estimates are integrated temp… Show more

“…More recently, Fang and Zhang [13] compared different open-source VO implementations: Libviso2 [15], Fovis [20], DVO [23], FastICP, Rangeflow [22], 3D-NDT [1], CCNY [11] and DEMO [63]. The evaluation is performed on two scenes of the TUM dataset and on a challenging dataset created by the authors with illumination changes, fast motion and long corridors.…”

“…However, in recent years researchers have begun to propose fast ICP-based registration methods. The fourth kind is based on depth image and range flow theory [25], [7]. The key idea of these methods is similar to dense visual odometry using RGB images.…”

“…Since we want to get a very fast odometry estimation with low CPU usage, we do not always incorporate the visual information into the depth image based odometry estimation method. Though joint optimization methods [20], [21] may get more accurate estimation, it is much more expensive to compute. In our system, we are not too concern with the accuracy of odometry estimation method since our localization algorithm can correct the drift of visual odometry.…”
