New AI calculates weak spots of table tennis players to help rivals analyze the game
New AI calculates weak spots of table tennis players to help rivals analyze the game
2023-06-12
Artificial intelligence is making its mark in the world of sport. Table tennis champion Tsao Tung-chun recently triumphed at the National Intercollegiate Athletic Games. She put her success down to AI software that, she says, helped her analyze opponents’ games. Engineers at National Chung Hsing University created the AI using a huge database of footage of table tennis matches. The program can calculate how a player’s balls usually land, to help rivals figure out their weak spots.
Table tennis player Tsao Tung-chun once more won the women’s singles gold at the National Intercollegiate Athletic Games in May. She’s the first to win three golds over four years. Aside from her rigorous training program, she credits an AI program as an invaluable aide.

It analyses what technique the athlete uses, where their balls land, what their spin is like, their power and speed.
Footage of players’ stances and the trajectory of their balls can all be analyzed with AI methods.

We pick out the key points, and at first it’s in 2D, but then we train it using our vast database.
AI can effectively work out a player’s blind spots, as well as their playing style. That lets you train the perfect counter strategy to disrupt your opponent.

After about one game, I’m now better at understanding that opponent’s strengths and weaknesses. I think AI has helped me get better at analysis.

We can capture the trajectories of table tennis balls with extreme precision. And if we can do that, then we can calculate where the ball is going to land, and after that we can work out the ball speeds and even the spin speeds.
AI is causing a revolution in so many different industries. Even in the world of sport, pure talent and intuition are no longer enough: Data can mean all the difference between gold and silver.
AI系統桌球戰技分析! 幫助52歲國手奪金牌
2023-06-12
AI技術，也被運用在體育界上，52歲的桌球國手曹彤君，上個月再度拿下全大運桌球女單金牌，創下四年摘三金的輝煌紀錄。努力摘金，除了自身實力和教練群幫忙，還有一套由大學研發出的AI系統，透過球路自動追蹤系統和戰技分析模擬分析，讓訓練更科學。
桌球選手曹彤君，五月再度拿下全大運桌球女單金牌，也創下四年奪3金的紀錄，實力堅強的她，除了有紮實的練球基礎，學校研發的AI技術，也成了培訓幫手。

“它就是每次的分析，這個選手他用的是什麼的技術，他的落點在哪，他的旋轉是怎樣，他的力量、速度是怎樣的”
透過鏡頭拍攝，選手的打球姿勢，還有發球球路，都能透過AI技術來分析。

“去把人的關鍵點找出來，先是2D的，但是我們有龐大資料庫去訓練”
AI技術可以有效，找到選手球路的盲點，甚至更加了解對手的球路風格，讓選手找出最佳的獲勝策略。

“大概一局之後，我就比以前更快了解到這對手的優缺點在哪裡，我就覺得AI讓我提高我的分析能力”

“我們可以把桌球軌跡，抓的非常精準，那如果有軌跡，於是乎我們可以去算落點出來，接下來把球速，甚至你的轉速，我們都可以計算出來”
AI在科技界颳起旋風，沒想到也能運用在體壇，幫忙選手訓練，找出贏球方法，精進球技。
