代码中启动ros节点roslaunch和rosrun

import subprocess
    import rospy
    import rosnode
    class launch_demo:
        def __init__(self, cmd=None):
            self.cmd = cmd
     
        def launch(self):
            self.child = subprocess.Popen(self.cmd)
            return True
     
        def shutdown(self):
            self.child.terminate()
            self.child.wait()
            return True
    
    if __name__ == "__main__":
        rospy.init_node('launch_demo',anonymous=True)
     
        launch_nav = launch_demo(["roslaunch", "pibot_simulator", "nav.launch"])
     
        launch_nav.launch()
     
        r = rospy.Rate(0.2)
        r.sleep()
     
        rospy.loginfo("switch map...")
        r = rospy.Rate(1)
        r.sleep()
     
        rosnode.kill_nodes(['map_server'])
     
        map_name = "/home/pibot/ros_ws/src/pibot_simulator/maps/blank_map_with_obstacle.yaml"
     
        map_node = subprocess.Popen(["rosrun", "map_server", "map_server", map_name, "__name:=map_server"])
     
        while not rospy.is_shutdown():
            r.sleep()

#include <unistd.h>
    //execlp函数的作用是从PATH 环境变量所指的目录中查找符合参数file的文件名，找到后便执行该文件
     execlp("roslaunch", "roslaunch", "runtime_manager","runtime_manager.launch", NULL);

ros中添加qt 增加Qt5SerialPor库

sudo apt-get install ros-kinetic-qt-create
    sudo apt-get install ros-kinetic-qt-build
    sudo apt install libqt5serialport5-dev

qtcreate :无法覆盖文件 /home/iimt/.config/QtProject/qtcreator/devices.xml : Permission denied

sudo运行qtcreator后，下次不使用sudo打开会报以上错误 /home/xxx/.config/QtProject/Qtcreator/qtversion.xml : Permission denied

原因：在sudo下打开qtcreator时，会向用户根目录的.config下写数据，所以这个目录变为管理员权限，使用下述命令就是将.config的管理员权限取消。

解决方式：

改变主目录下.config的权限，在home用户目录，终端输入：sudo chown -R iimt:iimt ~/.config/

注意改掉用户名：比如用户名为user，则输入的就是sudo chown -R user:user ./config/  
注意空格的位置。在用户名后面还有一个空格

python2启动服务器：

浏览器输入：`http://0.0.0.0:8000`即可看到目录下的文件

python -m SimpleHTTPServer

http server默认端口为8000，如果更改端口，可按如下格式

python -m SimpleHTTPServer 8080

python3启动服务器：

python -m http.server

python -m http.server 8888

Sub-process/usr/bin/dpkg returned an error code (1) 这个错误解决办法：

Sub-process/usr/bin/dpkg returned an error code (1) 这个错误解决办法：
    
    cd /var/lib/dpkg
    
    sudo mv info info.bak #即备份一个info
    
    sudo mkdir info #新建一个新的info目录
    
    然后采用以下命令重装那些出错的软件包
    
    sudo apt-get –reinstallinstall 软件包名
    
    开始我是想在一条命令中同时安装几个软件包，结果还是出现E: Sub-process/usr/bin/dpkg returned an error code (1) 。于是把新的info删掉，一个个地来安装，每装好一个软件包，就把info删掉，再新建一个，这样就没有提示E: Sub-process/usr/bin/dpkg returned an error code (1) 了。
    
    最后用原来的info.bak 替换新的info
    
    sudo -rf info
    
    sudo mv info.bak info
    
    之后输入 sudo apt-get update 和 sudo apt-get upgrade 以及sudo apt-get autoremove都不再有E: Sub-process/usr/bin/dpkg returned an error code (1)了

## 查看编码方式：import chardet ##

    def check_charset(file_path):
        import chardet
        with open(file_path, "rb") as f:
            data = f.read(4)
            charset = chardet.detect(data)['encoding']
        return charset
     
    your_path = 你的文件路径
    with open(your_path, encoding=check_charset(your_path)) as f:
        data = f.read()

Matlab 保存变量数据

positionerror2：Matlab变量数据

xlswrite('C:\Users\Administrator\Desktop\candata\1.xlsx',positionerror2)
    
    csvwrite('C:\Users\Administrator\Desktop\candata\1.csv',positionerror2)
    
    csvwrite('C:\Users\Administrator\Desktop\candata\1.txt',positionerror2)

保存后通过numpy读取数据：

data=np.loadtxt('1.csv',delimiter=',')

如报以下错误：

UnicodeDecodeError: 'gbk' codec can't decode byte 0xfb in position 4: illegal multibyte sequence

是因为你的电脑被加密了

解决方法是：

用这个csvwrite命令保存加密软件不能识别的文件后缀就没问题了

例：

csvwrite('C:\Users\Administrator\Desktop\candata\1.txtttt',positionerror2)
    
    csvwrite('C:\Users\Administrator\Desktop\candata\1.txtttt',positionerror2)

在通过python加载就可以了：

data = np.loadtxt('1.txtttt',delimiter=',')

## python-pip镜像源[¶][Link 1] ##

### 配置Python安装源[¶][Link 2] ###

临时指定安装源[¶][Link 3]

如安装opencv-python的3.4.0.12版本，可直接使用`-i`参数指定源

pip3 install -i https://pypi.douban.com/simple opencv-python==3.4.0.12

永久指定安装源[¶][Link 4]

每次临时指定源地址比较麻烦，可以通过以下方式配置永久源

在主目录创建.pip文件夹

mkdir ~/.pip

编写~/.pip/pip.conf

已复制sudo gedit ~/.pip/pip.conf

并添加以下内容

[global]
    trusted-host=pypi.douban.com
    index-url=https://mirrors.aliyun.com/pypi/simple/
    timeout=6000

此时，默认`pip install xxx`已经可以自动走镜像地址， 但是sudo模式下的pip和pip3并不能使用此镜像。所以要把这个pip.conf复制到`/root/.pip`目录下

sudo mkdir -p /root/.pip
    sudo cp ~/.pip/pip.conf /root/.pip/

可用的源有:

清华大学：https://pypi.tuna.tsinghua.edu.cn/simple 
    阿里云：http://mirrors.aliyun.com/pypi/simple/ 
    中国科技大学 https://pypi.mirrors.ustc.edu.cn/simple/ 
    华中理工大学：http://pypi.hustunique.com/ 
    山东理工大学：http://pypi.sdutlinux.org/ 
    豆瓣：https://pypi.douban.com/simple/

# 原有设置：

##  安装ROS 遇到报错 ##

Command 'rosluanch' not found, did you mean:

command 'roslaunch' from deb python-roslaunch

Try: sudo apt install <deb name>

首先确保名字正确：

![20201129172221990.png][]

而后：

1.  `usrname:~$ sudo apt install python-roslaunch`
2.  `正在读取软件包列表... 完成`
3.  `正在分析软件包的依赖关系树`
4.  `正在读取状态信息... 完成`
5.  `有一些软件包无法被安装。如果您用的是 unstable 发行版，这也许是`
6.  `因为系统无法达到您要求的状态造成的。该版本中可能会有一些您需要的软件`
7.  `包尚未被创建或是它们已被从新到(Incoming)目录移出。`
8.  `下列信息可能会对解决问题有所帮助：`
9.   
10. `下列软件包有未满足的依赖关系：`
11. `python-roslaunch : 依赖: python-roslib 但是它将不会被安装`
12. `E: 无法修正错误，因为您要求某些软件包保持现状，就是它们破坏了软件包间的依赖关系。`

参考后，运行了如下命令：

    usrname:~/catkin$ sudo python2 setup.py install
     
    usrname:~/catkin$ sudo python3 setup.py install (这一步可能报错，只需要按照指示做就好了，比如缺少catkin_pkg 模块，请采用pip3 install catkin_pkg安装）
     
    usrname:~/catkin$ mkdir catkin_ws (非必要，可以跳过的，其实没有作用，我个人是用来做ROS的工作空

## Ubuntu 默认是没有chkconfig命令的，需要手动安装。 ##

**使用终端安装命令：**  
sudo apt-get install sysv-rc-conf  
**如果出现问题：找不到该软件包,在sources.list文件中添加阿里的镜像源即可**  
cd /etc/apt  
先备份 cp sources.list sources.list.old  
vim sources.list  
**把下面阿里的镜像源添加进去**

更名为chkconfig  
sudo cp /usr/sbin/sysv-rc-conf /usr/sbin/chkconfig  
赋予权限：chmod 755 chkconfig  
验证是否成功：sudo chkconfig

**使用chkconfig来查看某个服务的运行级别和状态：  
chkconfig --list 服务名**

# ssh: connect to host 192.168.169 port 22: No route to host  #

出现这种原因是由于防火墙设置问题，要先检查防火墙的设置：

## 查看防护墙状态   service iptables status      关闭   service iptables stop      查看防火墙开机启动状态   chkconfig iptables --list      关闭开机启动   chkconfig iptables off  ##

## 多机部署ros  ##

# 多机部署ros
     
    > 主机和从机要在同一个局域网内
     
    1. 主机添加在hosts中添加所有节点的ip和主机名(主机配置)
     
       ```bash
       sudo gedit /etc/hosts
       ```
       > ip  主机名
     
      1.1
     
       sudo gedit ~/.bashrc
       
       export ROS_HOSTNAME=本机ip
       
       export ROS_MASTER_URI=http://主机ip:11311
       source ~/.bashrc
       重启控制台
     
    2. 从机配置master节点服务(主机也需要修改)
     
       ```bash
       sudo gedit ~/.bashrc
       
       export ROS_HOSTNAME=本机ip
       
       export ROS_MASTER_URI=http://主机ip:11311
       source ~/.bashrc
       重启控制台

问题1: ros环境中 opencv与ros冲突时删除 conda环境,是因为conda冲突,在ubuntu中建议不按照conda

问题2: ros多机互联后,一方收不到另一方的数据时需要在执行的那个控制台窗口执行 source ~/.bashrc

问题3: 如项目中使用的Qt 就必须加Qappliion

第二种:动态多机部署ros 方法:

主机:树莓派端配置

export ROS_IP=`hostname -I | awk '{print $1}'`
    export ROS_HOSTNAME=`hostname -I | awk '{print $1}'`
    export ROS_MASTER_URI=http://`hostname -I | awk '{print $1}'`:11311

从机:

export ROS_IP=`hostname -I | awk '{print $1}'`
    export ROS_HOSTNAME=`hostname -I | awk '{print $1}'`
    export ROS_MASTER_URI=http://树莓派的IP地址:11311

问题1:链接不上或找不到节点 可能ip问题  
输入

ifconfig

与

echo $ROS_HOSTNAME

查看ip是否一致  
 强制更改 本机ip; 把动态命令写死

export ROS_HOSTNAME=`hostname -I | awk '{print $1}'`

改

export ROS_HOSTNAME=192.168.1.10

动态命令在多网卡或网络中断会导致把本机ip发送给mast节点的ip不准确

    ## CvBridge介绍
    
    ![](img/2.png)
    
    CvBridge主要解决的问题是将Ros的Image数据与OpenCv的Image数据进行相互转换。
    
    **Ros Image to OpenCv Image场景**
    
    通常Ros Node和相机硬件进行数据交互，最终拿到的是 Ros Image类型数据。
    
    对于这种数据，我们希望通过OpenCv库进行图片数据的操作。但是OpenCv需要的是Mat类型的数据。
    
    因此，需要进行数据类型的转换。这种场景主要是需要对图片进行一下业务操作。
    
    **OpenCv Image to Ros Image 场景**
    
    OpenCv图片操作完成后的数据是Mat类型的，在业务场景中，如果其他节点需要这个数据的话，是需要订阅这种数据的。在Ros中，OpenCV的Mat数据是不可以在节点与节点间进行传输的，要传输只可以采用Ros的Image类型进行传输。此时就需要将OpenCv的Mat数据转换为Ros 的Image类型。
    
    ##  RosImage to CvMat(c++)
    
    **依赖配置**
    
    1. package.xml配置
    
       ```xml
         <build_depend>sensor_msgs</build_depend>
         <build_export_depend>sensor_msgs</build_export_depend>
         <exec_depend>sensor_msgs</exec_depend>
       
         <build_depend>cv_bridge</build_depend>
         <build_export_depend>cv_bridge</build_export_depend>
         <exec_depend>cv_bridge</exec_depend>
       
         <build_depend>image_transport</build_depend>
         <build_export_depend>image_transport</build_export_depend>
         <exec_depend>image_transport</exec_depend>
       ```
    
    2. CMakeLists.txt配置
    
       ```cmake
       find_package(catkin REQUIRED COMPONENTS
           roscpp
           rosmsg
           rospy
       
           sensor_msgs
           cv_bridge
           image_transport
       )
       ```
    
    3. 引入opencv库
    
       ```cmake
       find_package(OpenCV REQUIRED)
       ```
    
    4. 添加链接库
    
       ```cmake
       target_link_libraries(image_subscriber
           ${catkin_LIBRARIES}
           ${OpenCV_LIBS}
       )
       ```
    
    **转换代码**
    
    1. 引入头
    
       ```c++
       #include <image_transport/image_transport.h>
       #include <cv_bridge/cv_bridge.h>
       #include <sensor_msgs/image_encodings.h>
       #include <opencv2/imgproc/imgproc.hpp>
       #include <opencv2/highgui/highgui.hpp>
       #include "sensor_msgs/Image.h"
       ```
    
    2. 转换逻辑
    
       ```c++
       void topicCallback(const sensor_msgs::ImageConstPtr &msg) {
         const cv_bridge::CvImageConstPtr &ptr = cv_bridge::toCvShare(msg);
         cv::Mat mat = ptr->image;
         ...
       }
       ```

**ros开发时python加载静态文件的路径从 .src开始往下找**

**参考第一种，第二种可以尝试看效果**

1.py\_path当前python文件,同时适用于ros环境及非ros环境加载文件

    # 当前python文件所在目录
    dir_name = path.dirname(path.realpath(__file__))
    #通过拼接文的件路径,找到文件left.yaml;  path.join:自动判断文件夹dir_name是否需要带/
    file = path.join(dir_name, "./calibration/left.yaml")

## USB设备重置 ##

有时，可能会因为各种各样的原因，导致usb设备不能正常使用，我们可以通过c代码，给其发送reset重置指令，恢复其状态，从而避免重新拔插设备。以下我们直接编译一个工具对设备进行重置。

*  创建`usbreset.c`文件，写入以下代码：

/* usbreset -- send a USB port reset to a USB device */
    
    #include <stdio.h>
    #include <unistd.h>
    #include <fcntl.h>
    #include <errno.h>
    #include <sys/ioctl.h>
    #include <linux/usbdevice_fs.h>
    
    int main(int argc, char **argv) {
    
        const char *filename;
        int fd;
        int rc;
        if (argc != 2) {
            fprintf(stderr, "Usage: usbreset device-filename");
            return 1;
        }
        filename = argv[1];
    
        fd = open(filename, O_WRONLY);
    
        if (fd < 0) {
            perror("Error opening output file");
            return 1;
        }
        printf("Resetting USB device %s", filename);
    
        rc = ioctl(fd, USBDEVFS_RESET, 0);
        if (rc < 0) {
            perror("Error in ioctl");
            return 1;
        }
        printf("Reset successful");
        close(fd);
    
        return 0;
    }

*  执行编译命令

cc usbreset.c -o usbreset

此时，可在当前目录得到编译后的可执行程序usbreset

*  进行USB设备重置

> 查看设备及其驱动：`sudo lsusb -t`，找到其前边的总线、设备序号

如何创建ROS工作区，比catkin\_workspace更方便

1.  第一步：

> cd〜/

mkdir ROS\_WORKSPACE

1.  编辑.bashrc

> gedit .bashrc＃在〜/下打开.bashrc

然后，将以下内容粘贴到源代码/opt/ros/indigo/setup.bash后面：

> ROS\_WORKSPACE = $ HOME / ROS\_WORKSPACE

> 导出ROS\_WORKSPACE

> ROS\_PACKAGE\_PATH = $ ROS\_WORKSPACE：$ ROS\_PACKAGE\_PATH

> 汇出ROS\_PACKAGE\_PATH

**Install** eigen  看上面的(eigen安装是不需要编译的)

eigen\_example

In this demo project, it illustrate the basic operation of using eigen for pose processing and basic: dot, cross, inverse operation.

>  *  I have already include the eigen librarires in this folder: if you want to download by your own
>  *  download using: git clone [https://github.com/eigenteam/eigen-git-mirror.git][https_github.com_eigenteam_eigen-git-mirror.git] eigenLibrary

There is no need to compile eigen, just link to your project as:

>  *  include\_directories($\{PROJECT\_SOURCE\_DIR\}/eigenLibrary)

Then, under eigen\_example folder:

>  *  cd build
>  *  rm -r \*
>  *  cmake ..
>  *  make -j4

If you want to run the executable file:

>  *  ./eigenDemo
