摘要(Abstract):
针对倾斜摄影技术生产的三维模型是一个连续的整体,不能实现特定对象的单独管理和应用的问题,该文在分析了当前几种主流的单体化方法的基础上,提出了一种以矢量边界为基线,对倾斜三维模型进行物理切割的单体化方法。该方法以矢量多边形边界为基线,以三维模型为研究对象,从相交判断、基于TIN的切割和修正、基于纹理的切割和修正以及自动单体化软件设计4个方面进行了关键技术研究。经过实验和结果分析,算法的逻辑正确可行,运算效率较高,在面对大面积的三维模型时,健壮性和可靠性也得到了验证,是一种更加完善和更加自动的,能实现较快速度的单体分离,能积极促进倾斜摄影三维成果更加广泛应用的单体化方法。
