Description
Technical field
The present invention relates to the holographic imaging sand table system of a kind of space virtual technical field of imaging, particularly relate to a kind of base
In the three-dimensional digit holographic panoramic sand table system that the three-dimensional terrain of multi-vision aviation photography builds.
Background technology
Sand table is according to data such as topography, airphotos, on the spot landform, in proportion chi silt or other materials and soldier
A kind of model showing landform and ground target that chess makes.The features such as it is strong that it has third dimension, visual in image.Sand table purposes is wide
General, it can show the landform of combat area visually, represents the situations such as enemy and we position composition, deployment of forces and weapons configuration.Husky
Dish typically studies landform, enemy's situation, battle plan and rehearsal tactical application mainly for commander.Along with sending out of electronic computation technology
Exhibition, occurs in that the new technique of Synthetic Theatre of War situation, provides new ways and means for research operational commanding.At time of peace
Today, sand table is also commonly used to make economic development planning and the model of large-scale construction project, and it is visual in image, quite by planning decision-making
Person and the favor of engineers and technicians.In recent years, in CCTV's news channel, analog demenstration to disaster area is exactly a sand table
It is applied to take precautions against the leading case administering natural disaster work.The importance of sand table is self-evident, and during the war years, how many battlefields are by people
The military commanders of the sand table supply both sides being fabricated to various multi-form study battle plan；Peacetime, sand table exists again
Indispensable key player is played during economic development planning and opposing natural disaster.It addition, simulate table on sand table
Show and identify the latest development of antagonism each side, respectively can select action scheme according to latest development, and one on sand table, can be entered
The result of step analog representation and mark action of parties scheme antagonism is also that the another practical of sand table embodies, and is referred to as sand table and deduces.
But tradition sand table has its weak point, the precision of Simple sand table is relatively low, and permanent sand table manufacturing process is numerous
Trivial, the longest, will be the biggest if needing to move sand table workload the most exactly.Goods electronic sand map is for tradition sand table
's.Existing goods electronic sand map is mainly the combination of the new and high technologies such as remote sensing, GIS-Geographic Information System, three-dimensional artificial.It is by three-dimensional
Emulation technology is virtual out, have terrain information accurately, atural object represent the most directly perceived, browse conveniently, support attribute query,
The advantages such as the calculation of conformal analysis amount, simulation.The making of goods electronic sand map is more and more universal, but current goods electronic sand map fabrication techniques
Sand table be all the achievement of three-dimensional simulation technique, be shown in flat-panel screens when of display or project to a screen
On, the number of the person which limits observable or autonomy, the information being just as that all observers observe, to observation
Visual angle can only be controlled by a certain individual, or the observation route worked out in advance.So current goods electronic sand map also cannot be complete
Full replacement tradition sand table.
Along with the progress of science and technology, people there has also been new pursuit to the making of sand table, in order to meet new needs, resolves
Above-mentioned existing issue, the present invention regards technology based on complete, merges tradition sand table and the advantage of goods electronic sand map, it is provided that a kind of superior
Virtual reality holography display sand table system, studies battle plan for the personnel such as commander, officers and men and rehearsal tactics provides new
Means and method.
