AR Scanner is designed for Arcona AR World users.

It allows to collect and send terrain datasets to the Arcona server. The dataset consists of a video sequence, imu data (accelerometer + gyroscope) and gps.
On the Arcona server, the dataset will be processed and turned into a map of the area. 
After that, the owner of this mapped area will be able to remotely and accurately place 3D content on it, and all Arcona users in this area will be able to accurately position and observe 3D content.
