Fast Imaging And Processing Technology Of High-speed Flight Research

The aviation posture and velocity of high-speed flight are significant parameters for researching weapon system. So, research for measuring these parameters becomes valuable.In this thesis, feasible method of fast digital imaging for high-speed flight and the technology of processing it are studied and the processing procedure of each module is proposed. In this system, the technology of dual sparks shadowgraph photography and digital image processing is used to evaluate the position, the velocity and the aviation posture of high-speed flight. This system go near to realize the automated evaluation, and it needs not much experience which improves precision. Furthermore, getting the velocity from photograph comes true by using the technology of dual sparks shadowgraph.The IPX-16M3-L/G cameras, laser, PC, network cards, timing controller are used in the hardware system. This thesis mainly elaborated the technology of fast digital imaging for high-speed flight and image acquisition, algorithm to process two sparks shadow image and to extract the information about the flight, and the realization in addition.
