无人机自动驾驶GAAS学习一

building GAAS environment

基本依赖项

pip install \
	pandas \
	jinja2 \
	pyserial \
	cerberus \
	pyulog \
	numpy \
	toml \
	pyquaternion

Q1:程序“pip”尚未安装。 您可以使用以下命令安装：
sudo apt install python-pip
Q2:
Traceback (most recent call last):
File “/usr/bin/pip”, line 9, in
from pip import main
ImportError: cannot import name main
解决：
sudo gedit /usr/bin/pip
将

from pip import main  
        if __name__ == '__main__':  
            sys.exit(main()) 

修改为：

  from pip import __main__  
if __name__ == '__main__':  
    sys.exit(__main__._main())

安装依赖的包

sudo apt install -y \
	ninja-build \
	exiftool \

安装ros系统：安装 ROS Kinetic

sudo sh -c 'echo "deb http://packages.ros.org/ros/ubuntu $(lsb_release -sc) main" > /etc/apt/sources.list.d/ros-latest.list'
sudo apt-key adv --keyserver hkp://ha.pool.sks-keyservers.net:80 --recv-key 421C365BD9FF1F717815A3895523BAEEB01FA116
sudo apt-get update

Q1:W: GPG 错误：http://packages.ros.org/ros/ubuntu xenial InRelease: 由于没有公钥，无法验证下列签名： NO_PUBKEY F42ED6FBAB17C654
W: 仓库 “http://packages.ros.org/ros/ubuntu xenial InRelease” 没有数字签名。
N: 无法认证来自该源的数据，所以使用它会带来潜在风险。
N: 参见 apt-secure(8) 手册以了解仓库创建和用户配置方面的细节。
解决：
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys F42ED6FBAB17C654
Executing: /tmp/tmp.0ahh2pNlMq/gpg.1.sh --keyserver
keyserver.ubuntu.com

F42ED6FBAB17C654

sudo apt-get install ros-kinetic-desktop-full

Q1:
W: Possible missing firmware /lib/firmware/i915/kbl_guc_ver9_14.bin for module i915
W: Possible missing firmware /lib/firmware/i915/bxt_guc_ver8_7.bin for module i915

解决：
首先去到这个网址，你会看到很多固件的选择项，你选择自己缺的那个点击进去。

https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/i915

进去以后呢，点击plain就会下载了。
把缺的几个固件都下载好以后，把它们复制到/lib/firmware/i915下。

sudo rosdep init
rosdep update
echo "source /opt/ros/kinetic/setup.bash" >> ~/.bashrc
source ~/.bashrc
sudo apt install python-rosinstall python-catkin-tools python-rosinstall-generator python-wstool build-essential

install ros-gazebo plugins

sudo apt install ros-kinetic-gazebo-*

完成上列步骤后，你可以通过下面的命令来测试是否成功安装

roscore

source：使当前shell读入路径为filepath的shell文件并依次执行文件中的所有语句，通常用于重新执行刚修改的初始化文件，使之立即生效，而不必注销并重新登录

接下来，需要生成catkin工作空间，你所有的基于ROS的库都可以存放在此。

mkdir -p ~/catkin_ws/src

安装MAVROS

sudo apt-get install ros-kinetic-mavros ros-kinetic-mavros-extras

安装geographic lib :

wget https://raw.githubusercontent.com/mavlink/mavros/master/mavros/scripts/install_geographiclib_datasets.sh
sudo chmod a+x install_geographiclib_datasets.sh
sudo ./install_geographiclib_datasets.sh

PX4 Firmware配置

cd ~/catkin_ws/src
git clone https://github.com/PX4/Firmware.git
cd Firmware
git checkout v1.8.0
make posix_sitl_default gazebo

仿真运行：

roslaunch px4 mavros_posix_sitl.launch

检查连接

rostopic echo /mavros/state

git配置

sudo apt-get update
sudo apt install git
git config --global user.name "（这里填写你github上注册的名字）" git config --global user.email “（这里填写你注册邮箱的名字）” 
git config --list 回车就会显示你的注册名字和注册邮箱
ssh-keygen -t rsa -C ”（注册邮箱名）”

之后连续按三次回车就行了。

cat ~/.ssh/id_rsa.pub

把显示出来的代码全都复制下来
从终端的复制的代码，粘贴在key表单中

下载GAAS 包

git clone [email protected]:generalized-intelligence/GAAS.git

模型文件所在地址更新到环境变量中:

 echo "export GAZEBO_MODEL_PATH=${GAZEBO_MODEL_PATH}:/home/yyl/catkin_ws/GAAS/simulator/models" >> ~/.bashrc

将模型以及配置文件拷贝到对应文件夹中:

cp -r /home/yyl/catkin_ws/GAAS/simulator/models* ~/catkin_ws/src/Firmware/Tools/sitl_gazebo/models/
cp -r /home/yyl/catkin_ws/GAAS/simulator/worlds/* ~/catkin_ws/src/Firmware/Tools/sitl_gazebo/worlds/
cp -r /home/yyl/catkin_ws/GAAS/simulator/posix-config/* ~/catkin_ws/src/Firmware/posix-configs/SITL/init/ekf2/

打开无人机仿真模型：

roslaunch px4 mavros_posix_sitl.launch 

检查MAVROS连接情况:

rostopic echo /mavros/state

初始化无人机并启动：

cd /home/yyl/catkin_ws/GAAS/demo/tutorial_1/1_px4_mavros_offboard_controller
python px4_mavros_run.py

更新文件“

cd /home/yyl/catkin_ws/GAAS
git pull origin master

将 Gazebo 仿真用到的文件拷贝到 PX4 文件所在目录中:

cp -r /home/yyl/catkin_ws/GAAS/simulator/launch/* ~/catkin_ws/src/Firmware/launch/
cp -r /home/yyl/catkin_ws/GAAS/simulator/models/* ~/catkin_ws/src/Firmware/Tools/sitl_gazebo/models/
cp -r /home/yyl/catkin_ws/GAAS/simulator/worlds/* ~/catkin_ws/src/Firmware/Tools/sitl_gazebo/worlds/
cp -r /home/yyl/catkin_ws/GAAS/simulator/posix-config/* ~/catkin_ws/src/Firmware/posix-configs/SITL/init/ekf2/

启动仿真

roslaunch px4 sfm.launch

检查 MAVROS 的连接情况:

# 确保 "connected" 为 "True"
rostopic echo /mavros/state

通过 Rviz 来查看发布出来的摄像头图片:

rviz

选择 “Add”->“by topic”->”/gi/simulation/left/image_raw“， 之后你可以看到当前的左目摄像头信息

订阅并存储左目摄像头的信息:

rosbag record /gi/simulation/left/image_raw -O sfm.bag

起飞无人机：

python  /home/yyl/catkin_ws/GAAS/demo/tutoal_2/2_Struction_from_Motion/px4_mavros_run.py

控制无人机圆型飞行：

python /home/yyl/catkin_ws/GAAS/demo/tutorial_2/2_Struction_from_Motion/fly_circle.py

处理 Rosbag：

python bag2image.py --bag /home/yyl/sfm.bag  --output_path /home/yyl/piture    --image_topic /gi/simulation/left/image_raw

无人机自动驾驶软件系列 E03： 在无GPS环境下通过SLAM实现位置估

更新GAAS ：

cd /home/yyl/catkin_ws/GAAS
git pull origin master

将ROS的launch文件拷贝到PX4相应文件夹内:

cp -r /home/yyl/catkin_ws/GAAS/simulator/launch/*  ~/catkin_ws/src/Firmware/launch

将“(PX4_FIRMWARE_PATH)/Firmware/Tools/sitl_gazebo/models" 中的对应模型删除，并重新拷贝：

cp -r /home/yyl/catkin_ws/GAAS/simulator/models/* ~/catkin_ws/src/Firmware/Tools/sitl_gazebo/models/

编译openc出现的问题和解决：

Q1:-- Checking for module ‘tesseract’
– No package ‘tesseract’ found
– Tesseract: NO

解决：有两种方法，我测试第一种通过
1、

sudo apt-get install -y tesseract-ocr libtesseract-dev liblepto nica-dev
sudo pip3 install tesserocr pillow

2、安装Tesseract（来源https://blog.csdn.net/tintinetmilou/article/details/80212305）

sudo apt install git （如果没有下载git 需要执行去下载安装git）
git clone https://github.com/DanBloomberg/leptonica
cd leptonica
autoreconf -vi
./autobuild
./configure
make -j8
sudo make install

安装tesseract

git clone --depth 1 https://github.com/tesseract-ocr/tesseract.git  
cd tesseract  
./autogen.sh  
./configure --enable-debug  
LDFLAGS="-L/usr/local/lib" CFLAGS="-I/usr/local/include" make -j8 
sudo make install  
sudo ldconfig  

检测安装成与否

tesseract -v

Q2: Failed to find gflags - Failed to find an installed/exported CMake configuration for gflags, will perform search for installed gflags components.

解决：安装gflags（来源https://blog.csdn.net/weixin_44354586/article/details/89399763）
下载源码：

git clone https://github.com/gflags/gflags
cd gflags
mkdir build
cd build
cmake ..
make
sudo make install

Q3:The imported target “vtkRenderingPythonTkWidgets” references the file
“/usr/lib/x86_64-linux-gnu/libvtkRenderingPythonTkWidgets.so”
but this file does not exist. Possible reasons include:

• The file was deleted, renamed, or moved to another location.

• An install or uninstall procedure did not complete successfully.

• The installation package was faulty and contained
  “/usr/lib/cmake/vtk-6.2/VTKTargets.cmake”
  but not all the files it references.
  解决：（来源https://www.cnblogs.com/sincere-diligence/p/9336045.html）

  sudo ln -s /usr/lib/python2.7/dist-packages/vtk/libvtkRenderingPythonTkWidgets.x86_64-linux-gnu.so /usr/lib/x86_64-linux-gnu/libvtkRenderingPythonTkWidgets.so

Q4:没有安装flake8
解决：
有两种方式：
1、# 安装到特定版本

sudo python -m pip install flake8

我的是
sudo python2.7 -m pip install flake8

2、安装到默认python

python -m install flake8

未完，接下是GAAS 学习二…

阶段总结

（1）配置环境务必保证每一步是正确的，否则越到后面错误就越，因为包包依赖，包包关联。
（2）缺少那个包有4种解决的方法：1）sudo apt-get install （包名称）2）sudo pip/pip3 install （包名字）3）源码编译 4）百度 install （包名字）
（3）编译软件要看对应软件的安装说明（readme）
（4）对于出现找不到XX .XX版的问题，修改CmakeList文件，去掉版本的要求
（5）对于找不到XX的问题多半是依赖包没装全或者安装完没有sudo make install
（6）源码编译的步骤：
1）cd 文件夹
2）mkdir build
3）cd build
4）cmake …
5）make
6）sudo make install
（7）有时下载或编译的速度慢了，可以取消在重新来
