可穿戴技术、人工智能等多项 黑科技 亮相东京奥运会赛场|东京奥运会|人工智能

  据介绍,这次奥运会的田径赛场上将首次出现“3D运动员跟踪技术”。它能在几秒钟内提供运动员速度、身体角度、加速度、步长等方面的数据,实现对运动员3D形态的数据提取,这是过去运动员和教练用肉眼无法捕捉到的信息。该技术不仅对运动员的训练是很好的记录,还是一种全新的转播方式 在即时回放中对比赛亮点进行分析、解读和复核,能为奥运会观众带来全新的体验。   日本NHK网站介绍称,国际体操联合会引入日本富士通公司开发的人工智能(AI)技术打分辅助系统。该系统通过向选手的身体及其周边投射红外线,追踪选手的动作,并且实时转换成三维立体图像。根据图像,AI可以对于身体的旋转和扭动等细微动作做出分析,并结合过去的比赛数据,遵照打分标准,判断技术的完成度。   香港《南华早报》网站称,参加东京

放置在跑鞋、滑雪靴或自行车踏板上的力传感器,可为整个训练过程提供连续的数据流。教练利用这些数据来分析运动员易受伤部位和运动强度的关系。当然,根据数据量身定做训练计划也是重要的用途。 科技+装备 事半功倍 △3D打印手枪握柄 材料“黑科技”在体育上的应用还有很多。据“Popular Science”网站报道,早在2017年碳纤维板就用在跑鞋的鞋底了。 英国伯恩茅斯大学的体育科学家布莱斯·戴尔(Bryce Dyer)解释其原理时说,碳纤维板跑鞋是在鞋底缓冲层之间加入一层碳纤维板材料,以充当弹簧的作用。运动员跑步时,碳纤维板将被压缩,然后反弹,将更多的能量返回给跑步者。 科技加持 让训练更高效

Europe s oldest map is a carved stone slab from the Bronze Age CNN 2 hrs ago © From Bournemouth University A slab of stone, engraved with intricate lines and motifs dating to the Bronze Age, has been revealed to be Europe s oldest map, researchers say. Using high-resolution 3D surveys and photogrammetry, researchers re-examined the Saint-Bélec Slab an engraved and partly broken piece of stone that was discovered in 1900 but forgotten about for almost a century. Researchers from the French National Institute for Preventive Archaeological Research (Inrap), the UK s Bournemouth University, the French National Center for Scientific Research (CNRS) and the University of Western Brittany say the recent study of the stone has revealed it to be the oldest cartographic representation of a known territory in Europe.
