Abstract
The analysis towards sports competition is an important part of technical motion analysis. With the features of being able to measure at a distance and non-contact, motion video analysis system becomes the first choice of data collection and analysis in sports competition. However, due to some objective reasons, there is often a certain depression angle when shooting competitions. Through theoretical analysis and experimental verification, this paper analyzes the effects of video camera’s high angle shot to twodimensional and three-dimensional analytical results and proposes correction methods.
