GPS-lidar fusion with 3D city models

A GPS-lidar fusion technique implements a novel method for efficiently modeling lidar-based position error covariance based on features in the point cloud. The fusion uses a three-dimensional (3D) city model to detect and eliminate non-line-of-sight (NLOS) GPS satellites to improve global positioning.

The technique has potential application in UAV missions such as 3D modeling, filming, surveying, search and rescue, and package delivery.
