With the improvement of living standards, more and more people begin to realize the importance of good health. However, traditional physical exercise can only satisfy the needs of exercising and does little to do with improving health. Therefore, there is an increasing need for a piece of equipment which can detect the body motion parameter and reveal the physical state so as to develop a scientific and reasonable body-building plan, which is also reckoned as one of the trends of research in relevant realms. Probabilistic model is a powerful instrument to deal with nondeterminacy parameters. The establishment of probabilistic model can resolve such problems as the complexity and nondeterminacy of the motion process and the changing factors of the external environment, while traditional measuring method is hard to satisfy relevant requests. It is based on the previous reasons that this paper researches into motion parameter detection. During the research, relevant document literature is consulted and related research is conducted into the meaning and method of motion parameter detection and the theoretical basis and application method of probabilistic model and probabilistic reasoning. On the basis of the previous efforts, this paper researches into the composition principle and design method of the motion parameter detection system based on probabilistic model and accomplishes relevant design. The designed motion parameter detection system is tested for its reliability and accuracy through the comparison of measuring results of this system with those of the standardized testing equipment. The testing results demonstrate that the motion parameter detection system based on probabilistic model has relatively excellent performance and accuracy, can satisfy the detection demands in our daily life, and has the value to be further developed and promoted.
