Some key issues of real-time interpretation for optical measurement images in test ranges to design were researched and a real-time interpretation and estimation system was realized. Automatic Target capture, tracking and high precision location for interpretation features are the questions under probe. Shape similarity analysis, online region tracking and learning, and iterative contour registration were respectively used to locate multiple interpretation points. Based on the characteristics of real-time processing, such as high efficiency requirement, strong parallelism capability, and rigorous sequence in time, the software architecture design pattern of distributed framework with business process management was adopted to achieve the centralized administration of data and process, multiple sites parallel interpretation, data-driven auto estimation method selection and friendly user interface. Take the aerial launching tests of the air ranges as an example, the feasibility and efficiency of the system was examined by the experiment. The system can be extended to various test ranges to meet the users’ need of weapon test data’s real-time gain and analysis.
