Python Support Library to import and process Ridy files
Ridy is an Android App to record sensor data for uses in science and engineering. The app is currently actively being developed at the Chair and Institute for Rail Vehicles and Transport Systems (IFS)
At the institute Ridy is e.g. used for condition monitoring of railway tracks and several more use-cases are currently researched upon. Among other, Ridy can record:
- Acceleration
- Linear Acceleration (i.e., without g-Force)
- Magnetic Field
- Gyroscope
- Orientation
- GNSS Location (+ Android Raw GNSS Measurements)
- Pressure, Humidity, Temperature, Ambient Light
Compared to other existing apps Ridy can perform long measurements even in the background when the phone is locked. The app supports two formats for data export, JSON and SQLITE. If you would like to use or try out the app please contact the developer (see below) to get access.
PyRidy is the companion python library for the Ridy Android App. It provides easy access to the data no matter which recording format was used. If pyridy is used, one does no longer need to manually write code to import the files.
In addition, pyridy provides several more features:
- Automatic conversion of sensor data into objects and numpy arrays
- Conversion of arrays to Pandas DataFrame objects
- Time synchronization of individual files (e.g. from different phones)
- Download of OSM Railway Data via the Overpass API
- Plotting of GPS tracks onto a map using ipyleaflet
Install using pip
pip install pyridyInformation and examples on how to use the library can be found in the PyRidy documentation
