Target positioning and recognition method and device and readable storage medium

The invention discloses a target positioning and recognition method and device and a readable storage medium. The method comprises the steps that multiple face image information of a person target is acquired through an unmanned aerial vehicle group; determining a target edge device with the earliest completion time in the edge device group, and sending each piece of face image information to the target edge device; face image coordinates in the face image information are converted into a three-dimensional coordinate point set through the target edge device, and a face space position corresponding to the face image coordinates is determined according to the three-dimensional coordinate point set; and extracting face feature vectors in the face image information through the target edge device, and fusing the face feature vectors to determine identity information of the person target. The method is applied to a system composed of an unmanned aerial vehicle group and an edge device group, and high-precision posi
