Bowling Intelligence

Understand the complete bowling action

For bowling clips, Gabriella tracks the action through measurable stages and returns metrics and visualizations suited to that camera view — so coaches can review run-up speed, plus front-knee flexion at plant and arm angular speed where the take supports it.

What's live, conditional, and research-stage

Capability status for bowling analysis

Availability depends on camera view, calibration, visibility, and clip quality. The system reports "can't measure" when a metric cannot be reliably determined — it never substitutes a guess. Release height stays off this page until calibrated: no public metre, and no can't-measure slot.

Metric	Status	Condition
Run-up speed	Live	When pose is trusted — may show even if the ball is not seen
Arm angular speed	Live	When bowling-arm pose is ok
Front-knee flexion at plant	Live	When front-leg pose is ok. 0° ≈ fully extended — a measured angle, not a technique grade
Ball speed	Conditional	Ready when ball tracking is trusted; otherwise Can't measure (ball not seen, track broke, or impact missing)
Stride and gather position	Conditional	Requires lower-body visibility and a view that shows the approach
Follow-through alignment	Conditional	Where the bowler stays in frame after the delivery
Session-to-session comparison	Conditional	Requires clips from a comparable camera view and quality
Release height	Research	Omitted until calibrated — not a public metre and not shown as a can't-measure slot

Session metrics from this take

Demonstration output from selected sample clips. Not independently validated. Measurement availability and accuracy depend on camera view, calibration, visibility, frame rate, and clip quality.

Coaching questions, not engineering metrics

Answers the questions coaches actually ask

How consistent is run-up speed across this session?

Peak approach speed from pose, compared across takes that share a similar view. A measured value — not a technique grade.

What was front-knee flexion at plant?

Knee angle of the front leg at front-foot plant in this take. 0° ≈ fully extended. An observed angle, not an ideal shape.

How fast was the bowling arm through the action?

Peak arm angular speed in this take, when pose supports it. Observed speed — not a technique grade.

Session intelligence

Compare deliveries. Track progress.

Review bowling metrics across clips when takes share a similar view and quality. Longitudinal trends are the goal — strongest with consistent capture. Measured change, not an ideal angle. Front-knee flexion: 0° ≈ fully extended.

Illustrative sample data — trends need comparable views and clip quality.
