Development of support system for swim coaching by span-time information addition to video image

本研究旨在开发一种基于视频图像时空信息的游泳训练辅助系统，其主要研究内容如下：（1）开发了一种基于视频图像时空信息的游泳训练辅助系统。(2)在应用程序中安装了快速显示添加了时空信息的图像的功能。(3)本研究取得以下成果：（1）利用操作系统的应用程序接口和电子表格程序的宏功能，开发了视频分析应用程序。该系统实现了视频图像的加载、视频图像的控制、利用二维DLT方法从视频图像中获取时空信息，并将这些信息呈现在视频图像上。(2)在电子表格程序中增加了从时间信息中即时调用视频场景的功能，提高了实用性。(3)利用该训练支持系统，将增加了时空信息的游泳图像呈现给游泳教练。他们评价说，这很方便，因为想看的场景很快就能看到，信息量的增加对指导很有效。

The purpose of this investigation on the development of support system for swim coaching by space-time information addition to video image were as follows; (1) The system that adds space-time information to the swimming video image is developed. (2) The function to present quickly the image that added space-time information is mounted to the application. (3) The effect of use of this system during training or swim meeting is examined.The following result was obtained by this investigation ; (1) The video analysis application were developed by using the macro-function of the spreadsheet program and Application Programming Interface of Operating System. Functions were included that video image loading, control of the video image, acquisition of the space-time information from the video image by using 2-dimensional DLT method, present these information on the video image.(2) The practicality has risen by mounting the function that the scene of video can be instantaneously called from time information in the spreadsheet program.(3) The swimming image that added space-time information was presented to the swim coach by using this coaching support system. They evaluated that it was handy because the scene that wanted to see was able to seen soon, and an increase in volume of information was effective to coaching.
