Abstract
Systems, vehicles, and techniques are provided for the estimation of a linear velocity vector of an object. In some embodiments, a technique can include receiving first data indicative of first locations relative to an object at a first instant during movement of the object, and receiving second data indicative of second locations relative to the object at a second instant during the movement of the object. The technique also can include transforming the first data into third data corresponding to the second instant using at least one velocity vector hypothesis for a velocity of the object. The technique can further include solving an optimization problem with respect to a geometric volume of a convex hull of a union of the second data and the third data, and generating an estimate of a velocity of the object using a solution of the optimization problem.
