第三篇文章准备单独拿出来写，因为在大疆为人机的所有功能中，航线规划的功能最为复杂，也相当的繁琐，这里需要说仔细一点，可能会将代码进行多步分解。
1
航线规划
航线打点

在地图中手动选择点位选择完成航线打点；若打点位置错了可进行点位删除。

航点设置

可对航线点位进行设置，如飞行高度，速度（慢速:3m/s;中速: 7m/s;高速:10 m/s）、任务结束后操作及航向，点击[设置]按钮完成设置。

设置完成后会显示总距离及飞行总时间。

航线上传

点击[上传]按钮，进行航线上传。可以进入本地存储中选择航线文件进行上传，航线文件为 .kml结尾。

航线执行

点击 [开始]按钮，则可对航线进行执行。若中途需要暂停也可点击[暂停]安装进行暂停操作。

航线管理

按钮即可进入航线管理界面。
