- W2348156909 abstract "As the typical ground objects in near-ground visual navigation application,the three-dimensional geometrical models of trees can improve the visual precision and the reality of virtual scene. However,it may lead to the decrease in rendering efficiency of a wide forest scene and result in the loss of navigation precision. In order to boost the rendering efficiency to ensure the navigation precision and maintain the sense of reality,billboard clouds algorithm was employed to establish the multi-resolution tree models based on view distance and its disadvantages existing in near-ground visual navigation application were improved. To improve the visual navigation precision with high dynamic viewpoint in the nearground especially the nap-of-the-earth flight further,an accelerating rendering algorithm based on high dynamic viewpoint was proposed in accordance with the characteristics of limited horizon,threatened area and redundant vision. The contrast analysis of experiments testifies that the proposed algorithm improves the rendering efficiency,enhances the vision quality of the scene and raises the navigation precision of virtual scene." @default.
