Abstract: A semantic representation method and system based on an aerial surveillance video, and an electronic device are provided. The semantic representation method includes: taking a pedestrian and a vehicle in the aerial surveillance video as a target for tracking; inputting a coordinate track of the target into a first semantic classifier to output a first semantic result of the target; performing semantic merging on the first semantic result, and inputting an obtained semantic merging result into a second semantic classifier to output a second semantic result of the target; and performing cluster analysis on the first semantic result to obtain a target group of the target, and according to the target group of the target, the obtained scene analysis result and the second semantic result, determining semantics of the aerial surveillance video.
