Bubble Image Process Algorithm In Research Of Wake Optical Characterization

Wake is motive bubble film. Wake optical characteristics and application is a new domain of international and national science research, it has a important significance in military and civilian industry. Wake is motive bubble film, research of motive bubble is basis of Wake research. Using digital image process technology is a fire-new detection and analytic method. Compare with traditional method of motive bubble detection and analysis, it has some advantages, such as visibility, real time, high-efficient, easily realized in projects, and so on. Motive bubble's research result in optical, geometrical and movable characteristics widely applied in many domains. For example, guidance and control of fish torpedo, thruster of ship, supervision of water quality, medical ultrasonic instrument, ocean fish detection, etc. This dissertation put forwards a set of motive bubble image collection and analysis system, based on analysis of motive bubble film's optical characteristic, detective technology and detector characteristic. Firstly, according the character of motive bubble, analyse the requirements of image collection system, choose appropriate illuminating method, camera and data transfer device; based on those, build a motive bubble image collection platform. Collect a lots of bubble images which adapt to successive process. Secondly, based on different photographic method, bubble image is divided to static state motive bubble image, dynastic motive bubble image and sequence motive bubble image; according to each kind of image's peculiarities and possible bubble characteristic included in image, build different process procedure of motive bubble image. Thirdly, According to the result which detailedly analyse and choose optimum algorithms of every image process technologies applied in different process procedures, make whole motive bubble image process procedure integrity and realization. Finally, Using image process technology process the each kind of motive bubble image which get from experience, get the geometrical and movable characteristics of bubbles in motive bubble film, prove the feasibility of three kinds of motive bubble image processprocedures and detailed algorithms of every image process technologies in procedures.
