三维定点摄像方法在竞走运动中的应用研究

Application of Three-dimensional Fixed Point Videotape Method in Race Walking

通过查阅大量竞走运动相关文献资料发现,竞走技术的研究方法主要为平面摄影或摄像,对于竞走技术的深入研究在方法上存在明显不足,而在竞走规则修改后的十多年里,中国竞走运动员的"小步幅、高步频"技术受到巨大挑战。为了进一步深入探讨竞走运动技术特征,研究方法必须有所改进,对于竞走关键技术的研究,宜采用三维定点摄像方法,本文对三维定点摄像方法在竞走运动中的应用进行了探讨。

Through reviewing a large quantity of literature on the race walking, the author finds out that the main research method of the race walking is two - dimensional fixed - point videotape which has hindered the further technical research. So for more than ten years after the rules of the race walking were revised, the small steps and high frequency technique, which is adopted by our walkers, have been confronted with a big challenge. Therefore, in order to further the study in the technical characteristics of the race walking, the research methods must be promoted and as for the research in the key technique of race walking, it is good for adopting the method of the three - dimensional Fixed -point videotape, and this paper inquires deeply into the application of the dimensional fixed - point videotape.
