Litchi Waypoint Mission to DJI Fly Hyperlapse Mission Converter Instructions BETA!!! Litchi Mission Utilities Logo

Instructions

This application will convert a Litchi waypoint mission into a DJI Fly hyperlapse JSON file.

  1. In page one of Litchi Waypoint Mission to DJI Fly Hyperlapse Mission Converter:
    1. Provide a name for this hyperlapse mission. If no name is provided, the basename of the input file will be used.
    2. Set the time interval between photos. For fast-moving objects such as cars, use a small value of 1 or 2 seconds. For slow-moving objects such as clouds, use a larger value of 10 to 20 seconds.
    3. Set the desired hyperlapse duration in seconds.
    4. Specify a Litchi CSV file to be converted.
    5. Generate the hyperlapse mission and review the resulting parameters.
  2. In page two of Litchi Waypoint Mission to DJI Fly Hyperlapse Mission Converter:
    1. Review the displayed mission plot and mission data.
    2. Download the ZIP file.
    3. Uncompress the ZIP file to extract a hyperlapse mission folder.
  3. On the device running DJI Fly:
    1. Navigate to the hyperlapse folder.
    2. Copy the created hyperlapse mission folder created by Litchi Waypoint Mission to DJI Fly Hyperlapse Mission Converter to the hyperlapse folder on the flying device running DJI Fly.
  4. When ready to execute the hyperlapse mission in DJI Fly:
    1. Select the hyperlapse function
    2. Select the waypoints option
    3. Open the hyperlapse mission created with this utility
    4. Verify the hyperlapse mission parameters (such as interval and duration)
      • Each waypoint image will contain a waypoint number. Example: "Waypoint 3".
    5. Start the hyperlapse

DJI Fly Hyperlapse

DJI Fly hyperlapse waypoint missions can be created and then saved on the flying device. One disadvantage of this process is that the hyperlapse mission must be created with the drone in the air. This web application enables the conversion of a Litchi waypoint mission (in CSV format) into a DJI Fly hyperlapse mission stored in JSON format.

DJI Fly hyperlapse missions are stored in the "Hyperlapse" folder on the device running the DJI Fly application. Each hyperlapse mission is located in its only sub-folder and is comprised of a JSON file containing the mission parameters and two or more PNG image files that are displayed with each waypoint.

This application produces a ZIP file that must be uncompressed. The contents of the ZIP archive can then be copied to the "Hyperlapse" folder of the flying device. Unlike plain waypoint missions, there is no need to create a "dummy" hyperlapse to be overwritten. The new hyperlaps mission can simply be dropped into place in the "Hyperlapse" folder.

Notes

  • It is unclear which DJI drones support this hyperlapse format. I know the newer drones such as the Mavic 3/4 series, the Air 3 series, and the Mini 4/5 Pro do. If you successfully use this utility for other drones, please let me know.
  • DJI Fly imposes several constraints on the allowable distance and heading changes between waypoints in a hyperlapse mission. Because the exact limits of these constraints are not publicly documented, a Litchi mission that is valid in CSV format may not be valid as a DJI Fly hyperlapse mission without modification.
  • The altitude of DJI Fly hyperlapse missions has been found to be inconsistent for some. For reasons that remain unclear, saved hyperlapse waypoint missions will sometimes fly at an altitude different from their originally intended height. This issue has been reported by multiple users, yet DJI has not formally acknowledged it. As a result, caution is strongly advised when re-flying saved hyperlapse missions, including those generated with this utility. More information is available.
  • It has been reported that when the hyperlapse mission is executed, a duplicate hyperlaps mission is created. I have not experienced this so it is unclear what may have caused that.
