helloxss / dji-waypoints Goto Github PK

This script connects to the waypoints database in DJI Go Mod and, for each waypoint, looks up the elevation for the GPS position using the Google Elevations service, adds a configurable altitude value to the elevation and writes the new altitudes back to the waypoint.

The goal is to keep the drone at a fairly constant altitude in hilly terrain.

• This works for me but might crash your drone

• Requires that you obtain an API key from Google in order to access the Google Elevation service. It is very unlikely that you will exceed their free usage tier, but you will still need to register a payment method, such as a credit card, or bank account with Google.

• Works only with the hacked version of DJI Go, called DJI Go Mod

• Works only on Linux, due to dependency on go-mtpfs

• Install go-mtpfs

  • $ apt install go-mtpfs

• Clone this repo and enter it:

  • $ git clone <copy and paste the "Clone with HTTPS " URL from the top of this page>
  • $ cd dji-waypoint

• Prepare and activate a Python 3 virtual environment

  • $ python3 -m venv venv
  • $ . ./venv/bin/activate
  • $ pip install requests

• Obtain a API key from Google for the Elevation service

  • https://developers.google.com/maps/documentation/elevation/get-api-key

• Prepare and edit the settings

  • $ cp settings_sample.py settings.py
  • Edit settings.py
    • Replace the API key placeholder with your Google API key
    • Check and adjust ALTITUDE_M
      • To reduce the chance of a crash, starting out with a higher altitude than you think you need is probably a good idea

• On an Android device that has DJI Go Mod installed, set the USB configuration to MTP (Media Transfer Protocol)

• Connect the Android device to the Linux box via USB

• Run ./adjust_waypoint_altitude.py

• Create mission on the PC while leaving waypoint altitudes at the default value

  • https://mission.3d-log.com/

• Important: Take care to place the waypoints at the highest points in the terrain

• Download the mission to the Android device (or create directly on Android)

  • https://play.google.com/store/apps/details?id=ru.zalomskij.mission&rdid=ru.zalomskij.mission

• Run ./adjust_waypoint_altitude.py

• Upload the mission to the drone with DJI Go Mod and fly
