This article considers sports motion analysis. The technique is already in practical use, but it requires special expensive facilities and is seldom used for club teams in schools. So, we pursue sports motion analysis with minimal equipment such as a computer, a digital camera and some colored tape. We also suggest that this research theme is suitable as a graduation study for students who major in information technology in a technical college. Several reasons are: many students are interested in sports, this research theme does not require much funding, and it includes various small research problems to be selected and solved by students themselves.
