Research on the Algorithm in Accurate Matching between Military Simulation Entity and Terrain

Abstract

Research on the new method of resolving terrain contour matching of terrain protracting algorithm based on RSG and TIN provides basic data structure. The concept of Area of Interesting (AOI) is introduced, the algorithm of estimation and detection is also proposed to calculate reference point; The method comprised centroid constrained and intervisibility estimation achieves terrain contour matching calculation avoiding those problems such as low-efficiency of point inquiry, embeddability of moving object and terrain and the change of target’s stance. Experimental results show that this algorithm could not only keep the existing display performance but also make the model matching more conformed to the principles of nature and improve the reality of virtual environment effectively.
