航迹自动规划软件的部分代码
航迹规划是指在特定条件下，自动生成从初始点到目标点的最优运动轨迹，航迹规划是实现地形跟随，地形回避，威胁回避（TF/TA）飞行为目的的新一代低空技术，其目的就是要利用平时收集的地形等信息，规划出生存概率最大的巡航轨迹。

Delaunay三角网的生成
建立Voronoi图的关键是Delaunay三角网的生成。Delaunay三角网的特性：
（1）空圆性，任一三角形外接圆内部不包含其他点。
（2）最接近：以最近临的三点形成三角形，且各线段(三角形的边)皆不相交。
（3）唯一性：不论从区域何处开始构建，最终都将得到一致的结果。
（4）最优性：任意两个相邻三角形形成的凸四边形的对角线如果可以互换的话，那么两个三角形六个内角中最小的角度不会变大。
（5）最规则：如果将三角网中的每个三角形的最小角进行升序排列，则Delaunay三角网的排列得到的数值最大。
（6）区域性：新增、删除、移动某一个顶点时只会影响临近的三角形。
（7）具有凸多边形的外壳：三角网最外层的边界形成一个凸多边形的外壳。
Delaunay剖分是一种三角剖分的标准，实现它有多种算法。
本次采用Bowyer-Watson算法，算法的基本步骤是：
（1）构造一个超级三角形，包含所有散点，放入三角形链表。
（2）将点集中的散点依次插入，在三角形链表中找出其外接圆包含
插入点的三角形（称为该点的影响三角形），删除影响三角形的公共边，将插入点同影响三角形的全部顶点连接起来，从而完成一个点在Delaunay三角形链表中的插入。
（3）根据优化准则对局部新形成的三角形进行优化。将形成的三角形放入Delaunay三角形链表。
（4）循环执行上述第2步，直到所有散点插入完毕。
关键步骤2如下图所示：
步骤3的局部优化的准则指的是：
1.对新形成的三角形进行优化，将两个具有共同边的三角形合成一个多边形。
2.以最大空圆准则作检查，看其第四个顶点是否在三角形的外接圆之内。
3.如果在，修正对角线即将对角线对调，即完成局部优化过程的处理。
LOP (Local Optimization Procedure)处理过程如下图所示：
