Paper Abstract

The GE Advanced Technology Laboratories has developed an interactive graphic overlay system that employs closed circuit television (CCTV) cameras to facilitate the remote verification and maintenance of a geometric world model database. This database provides geometric models and locations of objects viewed by CCTV cameras and manipulated by telerobots. To update the database, an operator uses GE's interactive graphics system to superimpose a wireframe line drawing of an object with known dimensions on a live video scene containing that object. The technique used to align the wireframe and the video image is multipoint positioning. An important application of GE's interactive graphic overlay system is as an object designation function for the operator control station (OCS) of the Jet Propulsion Laboratory's Tel-erobot Demonstration System.
