==== IMPORTANT ====
Running this beta app requires login and password. It is provided automatically but if you have any problems, contact us at support@petioleapp.com.

The app may require a working Internet connection but it is also working without it.

The app uses OpenCV, so you need to install OpenCVManager from Google Play Store.

To calibrate the camera, you need a calibration pad with chessboard squares. Here is a link to download and print it out using white paper: http://bit.ly/2jHhHps
One square must have a size 10 x 10 mm.

Petiole currently was tested on Android 4.2 and higher. Please, write us if you have any problems with Petiole in your smartphone. Petiole is currently NOT working on tablets.

Note that the app is currently in BETA status, which means some things may not work as expected. We do our best to make Petiole better.
