Error while launching Stereo Camera

Error: [ERROR] [1531867243.908835120]: VIDIOC_STREAMON error 12, Cannot allocate memory

Did you try running only 1 camera? Also, how is the Pi's storage memory? Could you check?

[cmodi1]

I didn’t use pi as of now since I didn’t find its adaptor. Any one of the camera works fine and other one crashes.

Try decreasing the frame rate or resolution. Like this:

<launch>

    <node name="right" pkg="usb_cam" type="usb_cam_node" output="screen" >
      <param name="video_device" value="/dev/video0" />
      <param name="image_width" value="320" />
      <param name="image_height" value="240" />
      <param name="pixel_format" value="yuyv" />
      <param name="camera_frame_id" value="right_cam" />
      <param name="io_method" value="mmap"/>
      <param name="framerate" value="15" />
      <param name="camera_name" value="minoru_right" />
    </node>

    <node name="left" pkg="usb_cam" type="usb_cam_node" output="screen" >
      <param name="video_device" value="/dev/video1" />
      <param name="image_width" value="320" />
      <param name="image_height" value="240" />
      <param name="pixel_format" value="yuyv" />
      <param name="camera_frame_id" value="left_cam" />
      <param name="io_method" value="mmap"/>
      <param name="framerate" value="15" />
      <param name="camera_name" value="minoru_left" />
    </node>

</launch>

I tried with the frame rate of 15 as well and tried it on both laptop and desktop. I’ll try reducing the resolution. But the laptop’s camera and stereo’s one camera launches just fine.

You can connect the Pi to the laptop via Ethernet cable and use the Pi headless (and without wifi adapter). It was working on the Pi.

I meant power adapter, to power the pi.

The smart car had a small red board to convert the voltage down to the Pi's level. Is it wired? (Please see device's datasheet before wiring anything)

[cmodi1]

Okay I’ll do that!
