[ros-users] Trying to get bumblebee2 to work

[xr tay]

Hi Soonhac,

I try to change the video format to: <param name="video_mode" value="format7_3" />,
but when i launch the file, i got this error.

libdc1394 error: Error: Failed to allocate iso bandwidth
libdc1394 error: Error: Failed to setup DMA capture
[FATAL] [1297391608.293522530]: [camera] exception opening device: [Camera1394::open]: Failed to open device!

Thanks,
XR Tay

    Hi,

    

    If you're using BumbleBee2 v1.0, there might be two possibilities as
    follows.

    

    1. ROS version.

    BumbleBee2 v1.0 has been developed on ROS Box Turtle. For CTurtle,
    you may modify the code according to  http://code.ros.org/lurker/message/20100806.145740.e4fef600.en.html.

    

    2. Video Format.

    I think you may try alternative video format following to http://code.ros.org/lurker/message/20100614.205148.03c02b5c.en.html

    

    According to the recent similar issue, alternative video format
    would solve your problem. 

    If there is any additional doubt, feel free to contact me.

    

    Best,

    Soonhac

      Thanks for the reply from everyone, I manage to run the bumblebee2
      launch file and display the camera through RVIZ.

      

      The output from the /bumblebee2/right/image_raw was alright but
      the other output from the bumblebee2/left/image_raw

      was not properly display. The output was full of black and white
      dots on the image. When I cover one of the camera, I found

      out that the output was being produced from the right cam instead
      of the left cam.

      

      Anyone knows where it went wrong? Is it got to do with my
      bumblebee2 config?

      

      Here is my config:
