目前,利用真实世界的图像信息进行几何模型重建,并采用基于图像的渲染方法重建出高质量渲染结果成为一种获取高质量美术素材的解决方案。为此,提出了一个可视分析系统为无人机规划路径以及与之相关的三维重建和基于图像渲染提供支持。工程贡献上以蓝图编辑器作为可视分析系统的程序载体,将各种可视分析功能编写为蓝图编辑器中的功能节点,允许用户通过拖拽、连接和配置图形元素,自定义地创建用户所需的可视分析工作流。算法创新上提出了一种对基于采样覆盖率的参考视角选择算法的改进优化方案,比较了其他3种类型的视角选择算法后,通过对比实验证实了参考视角选择方案在运算的时间开销上和渲染图像的参考率上拥有更好的效果。

图8 对点云的预处理可以增强视角的选择效率((a)贪婪法无法保证选到最优参考视角组合;(b)优化后的点云作为输入可以辅助算法选择到更好的参考视角组合)
Fig. 8 The preprocessing of point clouds can enhance the selection effect of perspectives ((a) Greedy method can not guarantee the selection of reference view combination is good enough; (b) The optimized point cloud as input can assist the algorithm to select a better reference view combination)
