Photogrammetric reconstruction method has been a major issue in human motion studies. Extracting accurate motion data from economic equipment is a goal of the method. As a result of that, there have been much prates in hardware such as video system and in softwares which are available in the market. Although the commercial motion analysis systems are convenient to use, it costs much funds and requires frequent upgrade for changing computer operating system.
The purpose of this work was to provide low cost three dimensional video motion analysis program which can be run in 「Windows」 operating system produced by Microsoft company. This program enable us to work only the video recorder/player and video capture board. Once the video some is stored in the form of AVI file, the way of analyzing human motion is unlimited to the number of files or personal computers. Several filtering techniques are adopted to improve the accuracy of reconstructed data for different motion analysis. The accuracy of the data analysis for impact cases such as golf swing, volleyball spike, football kick, and Taekwondo chop, is greatly improved by use of split data processing technique which is not possible yet in most of other motion analysis programs available in the market.
