UNMANNED AERIAL VEHICLE-BASED TRACKING METHOD AND SYSTEM, UNMANNED AERIAL VEHICLE AND TERMINAL

摘要

Provided are an unmanned aerial vehicle (20, 20')-based tracking method and system, an unmanned aerial vehicle (20, 20') and a terminal (10, 10'). The tracking method comprises: an unmanned aerial vehicle (20, 20') flying according to an acquired search instruction and acquiring real-time images (S101); the unmanned aerial vehicle (20, 20') extracting information of an object needing to be tracked from a currently acquired real-time image according to target information from the terminal (10, 10') and the currently acquired real-time image (S103); the unmanned aerial vehicle (20, 20') calculating a matching degree of the target information and the information of the object needing to be tracked (S105); if the calculated matching degree is greater than a preset matching degree, the unmanned aerial vehicle (20, 20') sending feedback information to the terminal (10, 10'), so that the terminal (10, 10') generates a tracking instruction according to the feedback information (S107); and if the tracking instruction from the terminal (10, 10') is received, the unmanned aerial vehicle (20, 20') sending the current tracking information of the object needing to be tracked to the terminal (10, 10') (S109). Accordingly, tracking target information can be directly sent to the unmanned aerial vehicle (20, 20') through the terminal (10, 10'), with no need to select a tracking target from real-time images returned by the unmanned aerial vehicle (20, 20'). The present invention can be applied to a wider range of scenarios.
