易知最短路一定是以圆心或者两圆交点作为中间点到达的。所以把这些点拿出来建图跑最短路就够了。

现在，英国的一家公司Martin Aircraft已经打造出这种飞行器，并号称全球唯一真正的飞行背包。...与大部分“飞行背包”采用火箭和水蒸气喷射来提供动力不同，Martin Aircraft推出的产品利用喷气式涡轮实现垂直起降。

Lift Aircraft希望用户使用其18旋翼的“Hexa”无人机进行短暂的休闲飞行，而不是陷入城市无人机客运和监管框架中。
在这时，DroneBase推出了一个无人机AR平台AirCraft，允许用户操纵无人机在空中圈地跑马，创建一个属于自己的世界。 ?...DroneBase联合创始人兼CEO Dan Burton曾在一份声明中公开表示，AirCraft所提供的AR体验有着很大的区别，他说：“AirCraft能为无人机用户提供新灵感，因此我们更加期待，用户会如何使用这个平台...AirCraft帮助我们以一种完全独特的方式与世界互动。”...据悉，目前的AirCraft仅为测试版本，其已被整合到iOS的DroneBase应用中，兼容iPhone SE、iPhone 6及以上机型，用户可免费在App Store上下载该应用。...AirCraft安卓版本在不久的将来也会与用户见面。 ? VR/AR的出现，打破了我们的固有思想，让那些存在的在脑海里理所当然，以一种全新的样貌再次出现在我们眼前。
