China National Diving Team (中国国家跳水队)

Solution

Baidu AI Cloud built a '3D + AI' assisted training system for the China National Diving Team that combines cloud, edge, and on-site capture hardware with computer-vision analytics. High-speed cameras collect synchronized footage when an athlete steps onto the board and stop capture automatically when the athlete exits the water. AI services then classify and organize the clips and return them to coaches on tablets for immediate review. The system goes beyond conventional replay by applying 3D vision and deep neural networks to reconstruct the diver's body posture in three dimensions, estimate joint angles, and quantify key movements so coaches can diagnose the root causes of bad entries or weak takeoff. It also reconstructs the venue in 3D, extracts key actions, supports 360-degree free-angle replay, and automatically identifies dive types, difficulty coefficients, and scoring cues. That turns raw training video into a searchable, measurable coaching asset instead of an archive of unstructured footage.

Data flow

Training video is captured automatically by high-speed cameras, then passed into AI classification and clip-organization workflows that deliver results to coach tablets. Selected clips are reconstructed into 3D motion models, scored, and stored as reusable knowledge assets so coaches can compare posture, diagnose errors, and refine athlete guidance.
