Thanks for the inspo @measure_plan ! Auto-detects swing phases, computes tempo/posture, and spits out a coaching report.

• RF-DETR (Roboflow) → detects club, ball & player • MediaPipe Pose → body + shaft angles • OpenCV → annotated video + swing-plane overlay

i'm building an AI soccer coach to improve my shooting

using: - roboflow RF-DETR to detect the ball / net / player - mediapipe to record body angles when striking the ball - python to analyze and annotate the video

i'll also try adding a VLM into the pipeline for coaching feedback

@gregan8 @measure_plan super cool! how are you handling swing phase detection? rule-based off keypoints or did you train a separate model for it?

@gregan8 @measure_plan are you using your phone to capture video?

@gregan8 @measure_plan niiiiice. might have a new keypoint model for you to try soon

@endyjtwn @measure_plan Purely rules based right now.

I fooled with @roboflow to very simply train a model to detect the club head. I really should try classification or keypoint detection to find p1,p2,p3->etc...

I need to get it more dialed in, but heres latest... also able to generate a "skelton".

@masterbuilderAI @measure_plan Phone, yes. I think I need to capture a slow-mo video though so I get more frames. Going to try that this week.
