项目摘要

As the first research plan, determinate monitoring of timings and motions of take-off on ski jump was realized. In addition to this, although it is not accords FIS official rule, automatic measurement of flying distance using video and acceleration sensor was realized. Especially, flying distance is very important in ski jumping, however, since extra person(s) and equipment are required to measure, the flying distance is not measured in daily practice.Field use by only ski jumpers and coaches and feeding back deterministic results to beginner which are in first plan could not realized. This is because the research representative was taken to melancholia or known as great depression caused by over working and a gossip which had been deliberately speeded in the university by a person. As this result, the mental disease forced the research presentative to repeat being away from the university to rest and returning. The representative most mortified to be forced this.

作为第一个研究计划，实现了对跳台滑雪起飞时间和动作的确定监测。除此之外，虽然不符合FIS官方规则，但实现了利用视频和加速度传感器自动测量飞行距离。尤其是跳台滑雪中，飞行距离非常重要，但由于需要额外的人员和设备进行测量，因此日常练习中并不测量飞行距离。最初计划中仅由跳台滑雪运动员和教练现场使用并向初学者反馈确定性结果的情况无法实现。这是因为研究代表因工作过度和大学里有人故意加速的八卦而导致忧郁症或称为严重抑郁症。结果，精神疾病迫使研究代表重复离开大学休息和返回。代表最羞愧的是被迫这样做。
