A simple stereo camera library using PySpin.

Installation and User Guide (Spinnaker USB cameras on Linux)

  1. Increase USB file system memory. There are two ways:

    Permanent way:

    1. Open the /etc/default/grub file in any text editor. Find and replace:

      GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

      with this:

      GRUB_CMDLINE_LINUX_DEFAULT="quiet splash usbcore.usbfs_memory_mb=1000"

    2. Update grub with these settings:

      $ sudo update-grub

    3. Reboot and test a USB camera.

    Temporary way:

    1. Run the following command:

      sudo sh -c 'echo 1000 > /sys/module/usbcore/parameters/usbfs_memory_mb'

  2. After doing either the permanent or temporary way, confirm that you have successfully updated the memory limit by running the following command:

    cat /sys/module/usbcore/parameters/usbfs_memory_mb

    The output should be 1000.

  3. Configure udev rules to allow access to USB devices:

    cd /tmp
    wget https://github.com/justinblaber/stereo_pyspin/blob/master/spinnaker- -O spinnaker-
    tar xvfz spinnaker-
    sudo sh spinnaker-
  4. Install singularity

  5. Download singularity image:

    mkdir -p ~/stereo_pyspin
    cd ~/stereo_pyspin
    singularity pull --name stereo_pyspin.img shub://justinblaber/stereo_pyspin
  6. Set up acquisition folder and copy YAML configurations for each camera into it:

    mkdir -p ~/Desktop/stereo_pyspin_test
    cd ~/Desktop/stereo_pyspin_test
    wget https://raw.githubusercontent.com/justinblaber/stereo_pyspin/master/primary.yaml
    wget https://raw.githubusercontent.com/justinblaber/stereo_pyspin/master/secondary.yaml

    Make sure to modify primary.yaml and secondary.yaml to set the serial numbers and do the appropriate camera initializations.

  7. Run the singularity image:

    singularity run ~/stereo_pyspin/stereo_pyspin.img

    A gui should appear like so:

    alt text

  8. Find and initialize both primary and secondary cameras, then start the stream. If successful, the gui should look like:

    alt text

  9. After the stream is started, you can save images:

    16276941_2018-07-10_02:04:23_916915_1_L.png: alt text

    16276942_2018-07-10_02:04:23_918101_1_R.png: alt text

    It's important to note that the images should be acquired very closely in time (especially if a hardware trigger is used).
