航迹点导入大疆无人机_大疆无人机 预定航迹飞行

学习到了如何通过经纬度和海拔设置大疆无人机航迹飞行，记录如下：

1. 使用的软件是：DJI Pilot

2.通过航迹点（经纬度以及海拔）csv文件转为kml文件。(KML文件主要用于描述地球上的地理特征，如点、线、多边形、图层、图标等，以及与这些特征相关的属性信息。KML文件可以包含地理坐标、颜色、高度、图标等元素，使其能够用于在地图上呈现丰富的地理信息。)步骤如下：

参考链接(参考代码)

 准备一些航迹点，保存为csv文件，格式如下：

其中列分别是：点名、经度、维度、海拔高度、偏航角(注意所使用的大疆软件偏航角是否可以为小数，DJI Pilot软件不支持偏航角为小数，如果偏航角是小数在DJI Pilot中为0！)，云台俯仰角，无人机飞行的速度，转弯模式(可能的值包括"MANUAL"、"AUTO")，在航迹点执行的动作序列(可以没有任何动作，也可以有一个或多个动作。例如表格中动作为悬停1s并拍照)

• H1000 => 悬停 1000ms = 1s
• 拍摄 => 拍照
• G40 =>万向架 a -40°
• REC => 开始视频录制
• STOPREC => 停止录像
• A-170 => 将飞机转向 -170 。航向的范围为 [-180, 180] 度，其中 0 代表正北。

3. 利用Python脚本将csv转化为kml文件

将输入的csv文件进行修改，以及是否进行分割（DJI Pilot中每次飞行不可多于99个点所以我进行了切割）。 

4. kml文件制作完成后可导入到大疆的无人机软件中或者Google Earth中查看，例如：

 导入到大疆无人机控制软件中后即可进行飞行！注意不同软件可能有不同限制，例如DJI Pilot中每次飞行不可多于99个点且相邻航迹点不可过近，并且偏航角只能是整数。
