The technical scheme is that and be achieved in that:
A kind of interlock method of space observation territory and real-time three-dimensional Visual Scene, its method step is as follows:
(1) operation is shaken based on what the space of three-dimensional visualization scene observed observed object and observation area in territory
1. three-dimension visible sysem is started；
2. by identifying that observed object positioning instruction determines observed object, and in three-dimensional visualization scene, observed object is shown；
3. calculating current time is the position and attitude information that tracking observation target observation equipment should be located, and this position and attitude information is converted into the control instruction to scope；
4. scope will be reached under above-mentioned control instruction；
5. the position and attitude information fed back to according to scope determines whether scope has positioned；
6. calculating subsequent time according to current time is the position and attitude information that tracking observation target observation equipment should be located, and this position and attitude information is converted into the control instruction to scope；
7. scope will be reached under above-mentioned control instruction, it is achieved space observes the automatic tracing in territory to observed object and observation area；
(2) linkage of observed object and observation area and three-dimensional visualization scene in space observation territory
1. observation personnel's Non-follow control scope, the position and attitude information that it is current is uploaded to three-dimension visible sysem by scope；
2. the three-dimension visible sysem position and attitude calculating observation regional extent according to current time scope；
3. in three-dimensional visualization scene, show above-mentioned observation area；
4. observation personnel's Non-follow control scope makes its position and attitude change, and three-dimension visible sysem calculates current observation area scope according to the current location attitude information that scope returns, and shows observation area in real time in three-dimensional visualization scene.
The invention have the benefit that
In three-dimensional visualization scene, space observed object and observation area and long-range control observation equipment is set, it is achieved location and the tracking to observed object by the human-computer interaction interface of visualization technique；By the long-range control observation equipment of teleoperation, the attitude of scope and observation information are collected, and feed back to three-dimension visible sysem, space is observed scene in three-dimensional visualization scene, carries out panorama displaying, it is achieved the linkage of space observation area and observed object and real-time three-dimensional Visual Scene and information thereof.
The method of the invention is substantially reduced the space observation work competency profiling to observation personnel, improves scope utilization rate and observation quality, strengthens the effect of space observation, it is achieved the Automatic Control of space observation process and visualization.
