The present invention discloses a method and a device for target position surveying for an unmanned aerial vehicle, and an unmanned aerial vehicle. The method comprises the steps of: obtaining a target point to be surveyed; controlling an unmanned aerial vehicle to perform position selection movement for the target point to be surveyed; obtaining a position selection image collected by the unmanned aerial vehicle in the position selection movement, and determining a first surveying point having the same altitude as the target point to be surveyed according to a position of the target point tobe surveyed in the position selection image; controlling the unmanned aerial vehicle to flight to a second surveying point having the same altitude as the first surveying point; and calculating position coordinates of the target point according to a triangulation location structure formed by the first surveying point, the second surveying point and the target point.
