The Hong Kong Polytechnic University (PolyU) is committed to pioneering top-notch technologies for smart city development. Dr WEN Weisong, Assistant Professor of the Department of Aeronautical and Aviation Engineering of PolyU, was interviewed by Ming Pao Daily News to share how to develop a low altitude economy in Hong Kong.
Dr Wen and his team have developed a technology that employs drones for cleaning buildings’ external walls. By utilising laser radar and GPS positioning devices, the drone can scan a three-dimensional model of the building's exterior and automatically plan the best cleaning route. He anticipates the potential revenue from this industry could reach HK$300 million a year.
