ubuntu14.04 利用ros usb_cam包驱动摄像头后显示图像上下颠倒的解决方法

1、利用cv_camera(http://wiki.ros.org/cv_camera)包解决

$ mkdir -p ~/camera_ws/src

$ cd ~/camera_ws/

$ catkin_make

$ source devel/setup.bash

$ cd src

$ git clone https://github.com/OTL/cv_camera.git
$ cd ..

$ catkin_make
$ source devel/setup.bash

2、在cv_camera包下建立launch文件夹，并建立my_camera.lauch文件，launch文件内容如下：

<launch>

  <node name="cv_camera" pkg="cv_camera" type="cv_camera_node" output="screen" >

    <param name="device_id" type="int" value="0" />

  </node>

  <node name="image_view" pkg="image_view" type="image_view" respawn="false" output="screen">

    <remap from="image" to="/cv_camera/image_raw"/>

    <param name="autosize" value="true" />

  </node>

</launch>


3、执行launch文件

$ cd ~/camera_ws/

$ roslaunch cv_camera my_camera.launch
