Abstract

Traditional hidden surface removal algorithm based on hardware Z-Buffer technique cannot give attention to precision or efficiency at the same time when dealing with the non-uniform triangulated SAR (Synthetic Aperture Radar) scene model. A novel high-precision hidden surface removal approach using fast ray-tube splitting algorithm is proposed, where the SAR scene hidden surface removal problem is decomposed into two simple procedures, i.e. a Delaunay triangulator is used to generate the initial ray tubes from the projected point clouds of all incident visible vertices, then an adaptive ray-tube splitting method is adopted to carry out the complex scene shading situations and resultant visible model reconstruction. Simulation results of typical aircraft and T-72 tank show that, the new approach is feasible and effective.
基于自适应射线管分割法的复杂SAR场景隐藏面快速去除方法
传统的基于硬件Z-Buffer技术的隐面去除算法在处理非均匀三角合成孔径雷达场景模型时,不能同时兼顾精度和效率。提出了一种新的基于快速射线管分割算法的高精度隐藏面去除方法,该方法将SAR场景隐藏面去除问题分解为两个简单的步骤,即利用Delaunay三角剖分器从所有入射可见顶点的投影点云中生成初始射线管,然后采用自适应射线管分割方法进行复杂场景遮阳情况和由此产生的可见模型重建。典型飞机和T-72坦克的仿真结果表明,该方法是可行和有效的。
