An Android Application for Google's Tango devices based on their java-floorplan-example. It scans the surroundings automatically and generates a groundplan for the current location, once finished.
Clone this repository to your machine (e.g. C://Android/Projects/tango-groundplan).
Then, clone the official java examples at release MIRA and copy java_examples_utils and TangoReleaseLibs to the same directory (e.g. C://Android/Projects/).
Finally, import the project with Android Studio.
Note, that two approaches are tackled. One scans for walls (see according branch), the other scans for corners (see according branch).
Start the app, wait for about 10 seconds, tap on "Measure", and start moving the device slowly through your location. If it recognizes a room, it is highlighed and displayed in AR. Make sure to scan the walls in clockwise direction (move to your right). Once you're done, hit "Done" and the app will show you a groundplan of your location. Measurements in good conditions have been around 98% accurate.
Beware that moving the device too fast will lead to a crash of Tango and therefore the app. Very bright areas with direct sunlight can be difficult. As may be windows, reflective surfaces etc.
