http://www-video.eecs.berkeley.edu/papers/davidDeng2/1839.pdf WebIn this paper, we propose a novel method for estimating dense rigid scene ﬂow in 3D LiDAR scans. We formulate the problem as an energy minimization problem, where we assume local geometric constancy and incorporate regularization for smooth motion ﬁelds. Analyzing the dynamics at point level helps in inferring the ﬁne-grained details of motion.
