Detailed description of the invention
Embodiment:
Fig. 1～Fig. 3 shows that of this digital sand table with landform teaching demonstration function of the present invention is concrete
Embodiment, it mainly includes topographic sand table 1, height detecting device 2, optical projection system 3, processor 4.Its
In:
Topographic sand table 1, for artificially generated terrain, can carry out map function to it, artificially to simulate different ground
Shape condition.
Height detecting device 2 is located at above described topographic sand table 1, and it is used for detecting described topographic sand table 1
Surface height value everywhere, and the height value output that will detect.This height detecting device 2 typically uses light
Electric inductor, utilize its light sent to sense topographic sand table 1 upper surface everywhere to the distance of test point,
Obtain topographic sand table 1 upper surface height value everywhere.
Optical projection system 3 is located at the top of described topographic sand table 1, and it is for described topographic sand table 1 upper surface
Carry out projection operation.This optical projection system 3 can be simultaneously to the light of diverse location projection different colours.
Processor 4 is connected with described height detecting device 2 and optical projection system 3 respectively, and it is used for receiving height
The topographic sand table 1 upper surface height value everywhere of detection device 2 output, and according to topographic sand table upper surface everywhere
The difference of height value, controls described optical projection system 3 and projects different everywhere to described topographic sand table 1 upper surface
Color light, so that the surface of topographic sand table 1 presents different according to the difference of " height above sea level "
Color, to simulate the three-dimensional equal pitch contour of current landform.This processor 4 generally computer.And, additionally it is possible to
Animation light is projected to topographic sand table 1, with the geography such as natural wind simulating, sleet by described optical projection system 3
Scene, thus allow the person of receiving instruction obtain graceful multidate information true to nature vividly.
When instructor artificially changes the form of described topographic sand table 1, so that the landform style and features of its simulation occurs
During change, it is located at the height detecting device 2 above topographic sand table 1 and table on topographic sand table 1 detected the most in time
