Study And Design Of The Sub-system Of Swimming Pool Mointoring System

Vision system is the most important apparatus for human being and people acquire most of information from the outside world with their vision systems. In the process of human being's exploration to the nature world, man always hopes to find some machine-computing methods to achieve human being's vision function, and to acquire information automatically from the outside world. With growing up of digital image processing techniques, the supervision system has also been developed continuously, which has great significance for the guaranty of industrial production, people's lives and social security, and has been applied in various fields.With the development of underwater sports, the requirement to underwater lifesaving has been stricter. There are many unsafe conditions if the lifesaving just relies on the lifeguards. Therefore, it has great practical significance to study underwater supervision system. It is a challenge to design such a system because of the complicated underwater condition, and it makes the research of underwater supervision system have great scientific meaning. Swimming pool monitoring system includes four subsystems: main monitoring system, video database query system, swimming pool calibration system, wireless alarm transmitting system. The main content of this paper is designing the last two subsystems.First of all, the development of supervision system and the necessity of swimming pool monitoring system are presented briefly. The development of camera calibration and wireless transmitting techniques are also introduced, and the meaning of this subject is analyzed as well. One of the emphases in this paper is discussing the importance of swimming pool calibration for this monitoring system. Based on the existed calibration arithmetic, a new calibration arithmetic which is more convenient and more efficient is analyzed, the calibration program is also designed based on this arithmetic; the other is discussing the necessity of the wireless alarming transmitting system and designing this subsystem, the design method of which is also detailed.Finally in this paper, the summarization about the problems and difficulties occurred during the designing is presented, some improved method are suggested. The expectation about the whole system is given at last.
