TRANSFORMING SMARTPHONE INTO GEOSPATIAL VIDEO PROVIDER

Modern handheld devices, i.e. smartphones, have gone beyond their basic purpose for some time now. Beside powerful screens, which usually surpass those we use on our desktops, powerful cameras, and internet connectivity, these devices usually integrate many sensors. In this paper, we discuss how we can combine smart phone’s camera, connectivity, GPS receiver, accelerometer, and magnetometer in order to transform this kind of a device into geospatial video source. To validate and test suggested solution, we implemented a simple mobile app that fetches frames and sensors’ data, calculates georeference and streams geospatial video. In the paper, we also discussed limitations that are caused by the limited precision of used sensors
