About multicamera use

[YunchuZhang]

Hi, I want to ask does anybody know how to change the launch file to make multicamera works? I did not find any place to change ros ouput name field. Could somebody give some examples? Thanks!!!

I use the following launch file:

  <!-- Image size and type -->
  <param name="width" value="640"/>
  <param name="height" value="480"/>
  <!-- choose whichever uncompressed format the camera supports: -->
  <param name="video_mode" value="uncompressed"/> <!-- or yuyv/nv12/mjpeg -->
  <param name="frame_rate" value="15"/>

  <param name="timestamp_method" value="start"/> <!-- start of frame -->
  <param name="camera_info_url" value="file:///tmp/cam.yaml"/>

  <param name="auto_exposure" value="3"/> <!-- use aperture_priority auto exposure -->
  <param name="auto_white_balance" value="false"/>
</node>

change the first line's name does not work.

多加几个就行了，类似如下；我打开三个相机 `
