多年实践表明,田径运动发展水平的高低不仅与教练员的专业水平、运动员的个人素质以及掌握运动技能的能力等有紧密关系,还与科学技术发展水平及科学技术在田径运动训练中的应用水平有着极为密切的关系。而且,随着田径运动训练水平和科学化进程的不断发展和提高,田径科研与科技服务的应用水平也在不断的发展和提高。仅就图像技术处理这一个侧面来讲,在短短的几年内,就有了飞速的发展与进步。例如,从早期的影片摄影测量分析运动技术动作到模拟信号的录像摄像测量解析,再到目前普遍采用的数字信号的录像解析;从低速摄像、常速摄像到高速摄像;从低清晰度影像到高精度影像的发展;从黑白图
Years of practice shows that the level of the development of track and field not only has a close relationship with the professional level of coaches, personal qualities of athletes and the ability to master sports skills, but also with the level of development of science and technology and the level of application of science and technology in track and field training Has a very close relationship. Moreover, with the continuous development and improvement of track and field sports training and scientific process, the application level of track and field scientific research and technology service is constantly developing and improving. Only on the image technology to deal with this aspect in terms of just a few years, there has been rapid development and progress. For example, from the early film photogrammetric analysis of sports technical action to analog signal video camera measurement analysis, and now widely used digital signal video analysis; from low speed camera, normal speed camera to high speed camera; from low resolution image to High-precision image development; from black and white
