摘要

The invention provides a flying vehicle tracking method, which comprises an optical tracking in which a tracking light is projected to a retro-reflector of a flying vehicle with the retro-reflector, the tracking light is received, and a tracking of the flying vehicle is performed based on a light receiving result, and an image tracking in which an image of the flying vehicle is acquired, the flying vehicle is detected from the image, and the tracking of the flying vehicle is performed based on a detection result, wherein the optical tracking and the image tracking are executed in parallel with each other, and in a case where the flying vehicle cannot be tracked by the optical tracking, the optical tracking is returned based on the detection result of the image tracking.
