AirData to Litchi Converter Instructions

Instructions

This application will convert a CSV file from AirData or an SRT (subtitle file containing telemetry data) into a CSV file that can be imported into Litchi, resulting in a waypoint mission.

Synchronize your flight data to AirData
1. Fly your drone.
2. Synchronize your flight data to AirData.
  1. AirData provides well-written help files describing this process.
3. Select your flight in the list on the left side of the AirData dashboard.
4. Select "CSV" under the map of your flight. Save the CSV file to your computer.
In page one of AirData to Litchi Converter:
1. Select the type of data extraction desired:
  - Photos only: This type of extraction will detect where any photo was taken and output one waypoint per photo. If this option is used, the minimum distance setting is ignored.
  - Video only: This type of extraction will detect where any video was recorded and extract waypoints from that section of the log file.
  - Waypoint regions only: This type of extraction will detect where any waypoint path was flown and extract waypoints from that section of the log file.
  - Minimum Distance: This type of extraction will extract waypoints from the entire log file.
2. Choose whether or not to use the mission speed at each waypoint. If this is set to "no", the Litchi mission will simply use the cruising speed.
3. Select the minimum distance between waypoints. A log file contains data from every few milliseconds of a flight. This is a lot of data. Because waypoint missions do not require waypoints to be extremely close together, this option is used to specify an approximate spacing between them.
4. The flight log begins as soon as the drone motors are started (which is usually where the home point is also set). Choose the horizontal distance from the home point where the first waypoint is to be extracted.
5. Use the file chooser to upload your csv or srt file.
6. Generate the mission and review the resulting parameters.
In page two of AirData to Litchi Converter:
1. Review the parameters and calculations.
2. Download the csv file.
In the Litchi Mission Hub:
1. Use the Missions menu to import the csv file created by AirData to Litchi Converter.
2. Delete any waypoints that are not desired.
3. In "Settings" make sure that the "Heading Mode" is set to "Custom(WD)".
4. Adjust the Litchi mission parameters (such as speed or curve size) as desired
5. Go fly!

This application converts a flight log or SRT telemetry file into a Litchi waypoint mission, allowing a previously flown flight to be recreated as a waypoint mission.

Getting Started

To create a mission, you will need a flight log from the flight you want to recreate. The application supports the following flight log formats:

AirData CSV download: If you already sync your flights with AirData, open the desired flight in AirData and download the flight log in CSV format.
PhantomHelp CSV download: If you do not use AirData, you can upload a DJI flight log (FlightRecord*.txt) to PhantomHelp's DJI Flight Log Viewer. After processing the log, download the resulting CSV file, which is typically provided as a ZIP file. You can upload that ZIP file directly to this application without extracting the CSV file from it. Keeping the file zipped allows larger flight logs to be uploaded.
Litchi flight log: Litchi flight logs and Litchi SDK logs in CSV format are supported.
SRT file: This application can also extract flight telemetry directly from an SRT file. Because, SRT files do not have a universal telemetry format, SRT support should be considered experimental. If you have an SRT file that is not processed correctly, please let me know.

Recreating the Flight Path

This application places waypoints along the recorded flight path using the telemetry data from the uploaded file.

Keep in mind that the flight path of traditional Litchi waypoint missions do not pass through each waypoint. Consequently, the mission generated by this utility should be considered an approximation of the original flight. However, with a sufficient number of waypoints, the recreated mission will closely match the original flight path.
