Rolling target-based surrounding type circular mark point matching method

The invention provides a rolling target-based surrounding type circular mark point matching method, which comprises the following steps of: creating a feature coding mark point which refers to a combination of one or more same circular mark points; creating a surrounding type coding circular mark point, the surrounding type circular mark point being a characteristic coding mark point combination which is arranged on the surface of the throwing object rolling model and is divided into a head part and a tail part, the head part circular mark point set being recorded as {Head}, and the tail partmark point set being recorded as {Tail}; and extracting circular mark points, and matching the circular mark points. According to the method, the difficulty in identifying and matching mark points when the external store wind tunnel model moves in the six-degree-of-freedom direction is solved; hole forming and wiring of the externally-hung wind tunnel model are not needed, the aerodynamic shape ofthe externally-hung wind
