一种在三维场景中的定位算法

Positioning Algorithm in 3D Scene

针对三维场景中兴趣点定位问题,分析三维场景中旋转时地面兴趣点的偏移情况。根据三角形的相关定理,计算出偏移距离,得出一种用于三维场景中兴趣点定位的技术。与二维和2.5维地图中兴趣点定位效果进行比较,证明本方法在三维场景中定位准确。

Aim at the point of interest(POI) positioning in the 3D scene, this article analyzed the deviation of POI when the 3D scene rotating. According to the theorem related to triangle, the paper calculated the offset distance, and obtained a new POI positioning technology in the 3D scene. Compared with the positioning effects of 3D scene and 2D scene, the result shows that the positioning precision of this method in 3D scene is accurate.
