How AI swing analysis works

The quality of the analysis depends on the input. Practical rules:

• Full body in frame, head to feet, plus the clubhead on the backswing.
• Two classic views: face-on (camera facing the player) and down the line (behind, on the ball-to-target line).
• Fixed camera at waist or hip height, no zoom or movement.
• Clear light and clothing that contrasts with the background.
• One full swing, at real speed.

Pose estimation models locate body points (shoulders, elbows, wrists, hips, knees, ankles) in every frame. That produces a moving “skeleton”. Some products also rebuild the motion in three dimensions from a single video; that is the case with Sportsbox AI, which does 3D analysis from the phone.

In Morris, for example, the pose is measured with Apple Vision, and the result is four images with the skeleton drawn on and a verdict in about three minutes.

A swing is continuous, but coaches read it by positions. The system must decide which frame each one is:

1. Setup.
2. Takeaway.
3. Top.
4. Impact.
5. Finish.

Some systems add more, such as follow-through. In Badgie Golf’s swing analysis, since September 2026 the pose measurement delivers six moments: setup, takeaway, top, impact, finish and follow-through, and the result arrives in one to two minutes.

This is the part most often mistaken for “magic”. There are two phases:

Measure. Distances and angles between points (for example, spine tilt or shoulder turn relative to the hips).

Interpret. Going from the measurement to “what probably causes your ball flight”. Some systems combine pose with a vision and language model. In Badgie Golf’s case, the analysis makes two passes: one detects the view and the key moments, and another extracts faults, each with its confidence level, a single priority, backswing and downswing tempo, and drills.

That “confidence” matters. A diagnosis that does not distinguish “sure” from “possible” is a worse diagnosis.

A good analysis does what a good teacher would: it acknowledges what you do well and points to one thing. Twenty corrections at once cannot be worked on. The message should also be in player language (“you’re hitting it heavy because your weight stays back”) and not only in degrees.

There is a good honesty practice: do not quote angles in the message to the player and use them only as internal evidence. That is Morris’s standard in a swing verdict.

• See what the video does not show. A single angle hides swing plane, weight distribution or face angle at impact.
• Replace the radar. Video does not measure ball or club speed. Launch monitors do.
• Guarantee improvement. It is a reading, not a promise.
• Understand your body. Mobility, injuries or fatigue do not show on video.
• Correct by hand. That is the teacher’s job.

The ideal combines both: the radar tells you what the ball does; the video, why. On the launch monitor market, GMI estimates $234.4 million in 2025 and $523.5 million in 2035 (CAGR 8.6%).

1. Film two views with the same club.
2. Keep one priority.
3. Do drills with repetitions (for example, three sets of ten with one specific feel).
4. Film again after a few weeks from the same spot.
5. Take the video to your pro. It is the best combination. More in AI golf coach or human pro.
