Using a DEM to Determine Geospatial Object Trajectories
Tech. Report, CMU-RI-TR-98-19, Robotics Institute, Carnegie Mellon University, 1998
Abstract
This paper addresses the estimation of moving object trajectories within a geospatial coordinate system, using a network of video sensors. A high-resolution (0.5m grid spacing) digital elevation map (DEM) has been constructed using a helicopter-based laser range-finder. Object locations are estimated by intersecting viewing rays from a calibrated sensor platform with the DEM. Contin-uous object trajectories can then be assembled from sequences of single-frame location estimates using spatio-temporal filtering and domain knowledge.
