How To Use Your ScanLook Revolution

Mounting your Revolution

  1. Attach the provided quick release T-rail onto your platform of choice - this can be a car, truck, railcar, hyrail, uav, helicopter, boat, ATV, etc.
  2. Slide the quick release of the Revolution onto the T-rail. Hand tighten with the star bit torque wrench - do not tighten past the point of comfort as it may strip the threads of the screw.
  3. Connect your battery(10-30Vdc), antennas, and memory stick via the ports on the Revolution case.
  4. For users with L1L2 Tersus GNSS, see L1L2 Add-on

Connecting to Your Revolution's Lumberjack Logger

  1. Power on your scanner by pushing the LED push button on the side.
    1. Your scanner head should start spinning (for VLP16 and M8, you will only hear it spinning).
  2. Wait one minute and use your mobile device (computer, laptop, tablet, cell phone, etc.) to connect to the WiFi network of the scanner.
  3. REV1: The name format of the access point name is “Lumberjack[Company]AP” - i.e. LumberjackLidarusaAP. Password is “scanlook”.
    1. Open an internet browser from your device and enter “192.168.0.1:9000” into the address bar.
  4. REV2: The name format of the access point name is “[SerialNumber]AP” - i.e. RPV-16-0001-05AP. Password is “scanlook”. Web access page is “192.168.0.1”. These credentials are labeled on the exterior of the scanner.

At this point you will see a webpage similar to the one shown below


Project Setup

From the top right of the webpage, select “Settings” from the menu of options:

You will now see the screen below.

  1. Choose your preference for Automatic Logging of INS and LiDAR:
    • “True” means that every time the logging device is completely booted, it will automatically begin logging.
    • “False” means that the user must start and stop logging from the main screen.
  2. Select your LiDAR unit(Velodyne) and the VectorNav from the drop-down menus. See graphics below.
    • Example LiDAR Unit
  3. Choose your preference for Logging Location:
    • It is recommended to log externally to the FAT32 USB stick provided. This allows for easier transfer of the collected data.

Measuring Your Antenna Offsets

  1. Input your antenna lever arms (units are in meters). Note: When placing your antennas, be sure that they have a clear, unobstructed view of the sky from the vehicle and that they are approximately level.
    1. The positive axes follow the left hand rule - positive X is forward(vehicle direction of travel), positive Y is right, and positive Z is down.
    2. The reference points are at the center of the top of the Velodyne and at the center of Antenna #1 Port.
    3. Antenna #2 is measured in the same vehicle frame, but the point of reference is the center of Antenna #1
      • For best results, the two antennas should not be more than 1 meter apart from each other.

Choosing Your INS Script

  1. Choose the appropriate orientation Script based on how you have your scanner mounted to your vehicle.
    1. For example, see the image below of the Revolution orientation scripts.
  2. Select “Save” to retain your settings.
  3. Return to the Lumberjack Logger main screen by clicking the word “Snoopy” at the top of the webpage.

Calibrating Your Revolution

  1. Each time you readjust and reset your antenna offsets and INS script, you will have to calibrate your INS. This requires a 10-20 minute calibration period in which you must drive the unit while collecting VectorNav data until it reaches 100% calibration (shown on the home screen).
  2. For best results, stops and turns help the INS find its best heading and orientation. As a practice, we mount it exactly as it is going to be flown or driven for real data and begin by driving straight for 100meters reaching about 20mph (32km/h) and then driving figure eight patterns or making turns in different directions.
  3. Procedure is as follows:
    1. NOTE:For users with L1L2 Tersus GNSS, measure this antenna offset from the same reference point of the Revolution and write down to save for use in post-processing.
    2. Turn on the Revolution and connect to the WiFi and access the webpage. Tersus should have solid red lights.
    3. Set the Revolution antenna offsets and INS script. Hit “Save”.
    4. Return to home screen, change project name, and hit “Start” on VectorNav collection.
    5. Drive in a straight line for at least 100 meters.
    6. Then continue driving and making turns for 10-20 minutes or until “Calibration Progress” reaches 100%.
    7. End the recording and shutdown the Lumberjack from the menu bar shutdown tab.
    8. Once shutdown has been achieved, power cycle the Revolution and you are now ready to begin collecting your data.

Capturing Data with Your Revolution

  1. Name your project by pressing “Change Project Name”.
  2. For users with L1L2 Tersus GNSS, make sure Tersus Receiver is connected to an antenna and the Revolution (via the pigtail to COM1) before powering on and scanning. When properly attached and recognized by your Revolution, the lights on the receiver will glow red.
  3. To begin data recording, select “Start” on the home screen to begin recording VectorNav.
  4. Wait 1 to 2 minutes before beginning to record Lidar data.
    1. During recording, the data rates should steadily maintain capturing.
  5. When you have satisfactorily completed your project, press “Stop” on both units.
  6. You can then power down your scanner by going into the shutdown menu and shutting down the computer. Then press the LED button on the side of the Revolution and remove the thumb drive to process the data from it.

Transferring data from internal storage

If you've recorded data internally, power down your scanner and insert your FAT32 USB storage device. Power your scanner back up and log in. Open the “Sync” menu and choose the folder from internal storage from the drop down list. Select “Sync” and then “Eject” to removee the USB from the device. Then power down. This should copy the data folder to the USB drive.
