0 升级

遥控器升级到最新

• 遥控器连接手机,下载升级包,手机直接升级

飞行器固件升级 1.3.1.0

• 连接windons下DJL Assistant 2 软件,自动升级
• 升级过程不能中断,否则失败

升级说明,

1 硬件连接

手机+遥控器

• 开启切换模式, 取消新手模式
• 遥控器接入F挡

飞机+电脑

• 开启USB-TTL 连接,NUC靠近开关黄色的USB口(USB0端口)
• 飞机USB小口连接另一台电脑,打开DJL Assistant 2 软件
• 设置串口波特率,开启SDK对勾

2 程序启动

在电脑上

1. 编辑启动文件并在指定位置输入您的应用程序ID，密钥，波特率和端口名称：

rosed dji_sdk sdk.launch

　　

首先获取usb端口打开权限

echo 12 | sudo chmod 777 /dev/ttyUSB0

运行官方运行文件

roslaunch light_wings passThrough.launch

运行控制节点

rosrun dji_sdk_demo demo_mission

当然可以写脚本一次运行 run.sh

#!/bin/bash

cd /home/light-wings/DJI/djim100_ws
echo 12 | sudo chmod 777 /dev/ttyUSB0
roslaunch light_wings passThrough.launch
exit 0

接着可以看到windos电脑下运行的DJL Assistant 2软件能够模拟飞行

官方样例

云台测试

115200

windos assitans 2 设置波特率

ls /dev/tty*    //查USB端口
echo 12 | sudo chmod 777 /dev/ttyUSB0   // 给权限
roslaunch dji_sdk sdk.launch

地面获取视频

飞机视频---------------------遥控器+视频卡+电脑+运行USB视频读取

这里写了个节点

运行命令

rosrun my_image_transport my_subscriber

代码

#include <ros/ros.h>
#include <image_transport/image_transport.h>
#include <opencv2/highgui/highgui.hpp>
#include <cv_bridge/cv_bridge.h>

using namespace cv;
using namespace std;

void imageCallback(const sensor_msgs::ImageConstPtr& msg)
{
  try
  {
    cv::imshow("view", cv_bridge::toCvShare(msg, "bgr8")->image);
  }
  catch (cv_bridge::Exception& e)
  {
    ROS_ERROR("Could not convert from '%s' to 'bgr8'.", msg->encoding.c_str());
  }
}

int main(int argc, char **argv)
{
  ros::init(argc, argv, "image_listener");
  ros::NodeHandle nh;

  Mat im;
  VideoCapture cap(0);

  if(!cap.isOpened())
  {
      cout << "fail open." << endl;
  }

  while(true)
  {
      cap >> im;

      cvNamedWindow("im", 0);
      imshow("im", im);
      cvWaitKey(1);
  }

  //cv::namedWindow("view");
  //cv::startWindowThread();
  //image_transport::ImageTransport it(nh);
  //image_transport::Subscriber sub = it.subscribe("/stereo_camera/right/image_raw", 1, imageCallback);

  //ros::NodeHandle nh1;
  //cv::namedWindow("view1");
  //cv::startWindowThread();
 // image_transport::ImageTransport it(nh1);
 // image_transport::Subscriber sub1 = it.subscribe("/stereo_camera/left/image_raw", 1, imageCallback);

  //ros::spin();
  //cv::destroyWindow("view");
  return 0;
}
