1. A method for locating a human target using superficial vein characteristics, comprising:
acquiring a model displaying both of the human target and superficial veins;
projecting the model on a body surface where the superficial veins are located, so that a ratio of a projection on the body surface to actual dimensions of a human body is (0.9-1.1): 1; or printing, by using a transparent material, the model according to a size ratio, (0.9-1.1): 1, of the model to a human body so as to form a superficial vein mold; and
adjusting a position of the projection of the model, observing the superficial veins, and making at least two of the superficial veins coincide with veins in the projection of the model, and determining that a position of the human target in the projection of the model is a projection of the human target on the actual body surface; or placing the superficial vein mold on the body surface, adjusting a position of the superficial vein mold, observing the superficial veins, and making at least two of the superficial veins coincide with veins in the superficial vein mold, and determining that a position of the human target on the superficial vein mold is a projection of the human target on the actual body surface.
