Abstract

A method of estimating a kinetic state of a rigid body is disclosed. A LiDAR sensor receives multiple point clouds. A processor determined a rigid body transform for a pair of the received point clouds and obtains a sample space of previous rigid body transforms. The processor then identifies a proposal distribution that represents the probability that any rigid body transform in the sample space best aligns a subset of points of a first point cloud of the pair to a subset of points in a second point cloud of the pair. The processor then uses importance sampling to identify a probability distribution for the rigid body transform that best aligns the subsets of points, It then uses the identified probability distribution and a history of probability distributions to estimate a kinetic state of the rigid body.
