Abstract:
A system uses range and Doppler velocity measurements from a lidar system and images from a video system to estimate a six degree-of-freedom trajectory of a target and generate a three-dimensional image of the target. The system may refine the three-dimensional image by reducing the stochastic components in the transformation parameters between video frame times.

Claim (Index 1):
A system for refining 3D images, the system comprising:\n a lidar subsystem configured to direct at least two beams toward the target, generate a first set of line scan 3D measurements for a plurality of points on the target for a first beam of the at least two beams, and generate a second set of overscan 3D measurements for the plurality of points on the target for a second beam of the at least two beams; a video subsystem configured to provide a set of the video frames of the target; and a processor configured to:\n receive, from the lidar subsystem, the line scan 3D measurements and the set of overscan 3D measurements, \n receive, from the video subsystem, the a set of the video frames of the target, \n determine, at each frame time, a plurality of \u0394z offsets between pre over-scan measurements and the line scan 3D measurements and post over-scan measurements and the line scan 3D measurements, and \n adjust a plurality of transformation parameters based on a least square optimization.
