Abstract

The invention discloses a method and a system for accurately positioning an aerial target of an unmanned aerial vehicle. The method comprises the following steps: constructing a space coordinate system of a first activity range of a first target; obtaining a first color distribution feature of the first target; obtaining a first color distribution analysis result of the first target area image; performing color fading processing on a first region, exceeding a preset color comparison threshold value, of the first target region image; performing target feature matching to obtain a first target feature matching result; and obtaining a first target coordinate based on the first target feature matching result and the first construction result. The technical problem that in the prior art, spatial position coordinates of an aerial target cannot be rapidly obtained, and the shooting efficiency of an unmanned aerial vehicle is further low is solved. The technical effects of accurately distinguishing the aerial target from the surrounding environment based on the color features, further obtaining the accurate spatial position coordinates of the aerial target and finally improving the shooting efficiency of the unmanned aerial vehicle are achieved.

Description

technical field [0001] The present invention relates to the field of artificial intelligence, in particular to a method and system for precise positioning of aerial photography targets of unmanned aerial vehicles. Background technique [0002] With the development of science and technology, UAVs with advantages such as high mobility, high resolution, low cost, strong concealment, and flexible operation have been developed and used unprecedentedly. UAVs are easy to take off and land, and can take off at any time according to the mission, and can perform tasks that are not suitable for manned aircraft, and the acquired image data is very time-sensitive. However, in fact, for non-ground aerial photography targets, the existing positioning system only automatically recognizes and tracks the target based on its shape and structural features, so it is actually unable to give the accurate spatial position of the target, which leads to the inability of the UAV to accurately capture ...
