Thirty body points tracked to refine every golf shot
Bryson DeChambeau's system uses deep learning with proprietary 2D and 3D models. The models track more than 30 key points on the body, club, and ball through top of swing, impact, follow-through, and finish. Outcome metrics such as club speed and ball flight are recorded automatically.
Practitioners replace broad feel-based corrections with precise timing and position data at each swing phase. Training sessions become repeatable experiments that log numerical changes after each adjustment. This replaces trial-and-error range time with data-driven iteration.
Bryson DeChambeau has published results on the Google Cloud blog showing consistent tracking of 30-plus body and club landmarks during practice sessions.
Step 1: Record your swing with any high-resolution camera and upload the file to Google Cloud's Vertex AI video analysis pipeline. Step 2: Apply the pre-trained pose model that extracts the 30 key points and timestamps each phase of the swing. Step 3: Export the CSV of joint angles and club positions, then import it into a spreadsheet to calculate average deviation at impact. https://cloud.google.com/vertex-ai
