We are developing a real-time-multiple-target-tracking system using a wide-field-of-view (WFOV) camera. The high resolution WFOV camera was conceived as part of the Strategic Defense Initiative Research at Lawrence National laboratory. The camera system consists of a lens made of concentric solid blocks of index matching glasses, CCDs arrayed on the focal plane, and a custom VLSI image processor to extract the targets. References 1 and 2 describe the basic design of the WFOV camera and the prototype system that we have constructed. In this paper, we will briefly review the existing prototype system, the on-going effort to cover the full field of view using digital CCD cameras, the production of custom VLSI chips developed to extract centroids in real time, and the implementation of transputers to run the tracking algorithms. Currently, we completed the testing of prototypes of the camera electronics, the ACE board, and the transputer interface board. We have now started the production of the 23 units. We have successfully run the tracking algorithm across 3 nodes on simulated tracks. We anticipate that the complete system will be up and running by the summer of 1990. In conclusion, we have demonstrated the capabilities of the WFOV camera lens. We have developed a real time multiple target tracking algorithm for processing the signal from this WFOV camera system. We are developing a full field of view system with > 5 x 106 pixel elements using custom VLSI chips and a highly parallel image processing architecture which we will use to construct a high quality database for low earth orbit satellites.
