REAL TIME THREE DIMENSIONAL GEO-REFERENCED DIGITAL ORTHOPHOTOGRAPH-BASED POSITIONING, NAVIGATION, COLLISION AVOIDANCE AND DECISION SUPPORT SYSTEM |
摘要 |
Herein is presented a positioning, navigation and collision avoidance system for ships, aircraft, land vehicles and the like, which utilizes a geo-referenced digital orthophotograph data-base and a positioning signal to display upon a computer stereo graphics device a high visibility dynamic photographic image of the user's immediate environment, including both moving and stationary obstacles. The position and temporal data along with the geo-referenced elevation data utilized to derive the digital orthophotograph(s) can serve to warn the user of nearby obstacles; and optionally, to implement semi-automatic avoidance. Substituting user generated x-y-z positions and times, the system may be used in a static mode as a flight simulator or a simulator for other modes of transportation. The system may also be used as a mobile Geographic Information Systems decision-making tool with the addition of user-supplied geo-referenced digital data layers. |
