Technical Assignment for Skylark Drones

Modules required:

  • piexif: Python package to simplify exif manipulations.
  • pysrt: Python library to edit and create SubRip files.
  • geopy: Geocoding library for Python.
  • simplekml: Python package to generate KML with as little effort as possible.

You can use these commands to install these modules:

  pip install simplekml
  pip install pysrt
  pip install geopy
  pip install piexif

The script takes two parameters:

  • VID_RADIUS: Radius used for the video with the drone coordinates at different times.
  • POI_RADIUS: Radius used for the points of interest CSV file.

• Reads the SRT files in the video directory which contain GPS coordinates of the drone at the all the different times that the drone flew over the survey site.

• Creates a map of geotagged images from image names to their coordinates.

• Outputs a CSV file containing a list of images within the given radius at each second of the drone's flight. Also, generates a KML file of the drone's path in the videos in the video directory.

It reads a CSV file with some points of interests and their coordinates to create another file containing a list of images within the given radius at each point of interest.

Example usage:

  python script.py 35 50
