This video replaces an earlier upload demonstrating the extraction of 3D detail for buildings and/ or terrain from high resolution drone aerial photographs using photogrammetry and geo-referencing. This version includes high definition footage from a simulated autonomous circular aerial survey of an industrial asset, incorporating VidiAir’s precision ground survey control points (significantly more accurate than Google Earth), EMF/ RF protection and laser range-finding with telemetry – an important consideration when flying in close proximity to structures/ obstacles, particularly in gusting winds.
