College Basketball Computer Vision

Phase 1 – Proof of Concept

  • Can it be done?
  • What tools are available?
  • Everything running at home

Phase 2 – FULL Game Learnings 

  • Use existing consumer grade camera
  • Process a recent game using cloud resources
  • Determine what is beneficial
  • Create rules for subjective values (contested shot, good pick...)
  • Manual effort to correct camera shortcomings: 8 hours for tracks and 4 hours for plays = 12 hours total

Phase 2 – Consumer camera issues

  • Players found per frame, average 7.9 named players
  • Frames with the ball found 77.4%
  • Lose all players when the camera pans during transition
  • Distances are not exact due to occlusion
  • Practices are not feasible with jersey number only on back

Phase 3 – Improve Automation

  • Multiple mounted camera infrastructure
  • Streamlined workflow
  • Less touches and effort
  • Practices could be processed
  • Manual effort improvement estimates: track fixes 1 hour, plays 2 hours = 3 hours total

Phase 4 – Computer Vision

  • Training with a library of examples, i.e. what is a pick?
  • Requires extensive tagged examples
  • Library may be available for purchase in future

Future Uses

  • Scouting – identify opponent tendencies
  • Portal / Recruiting – focused tracking of individual players.  Other products
  • Pose technology – identify body parts to get detailed measurements for distance and movement
    • Shooting technique
    • Defensive distance for ball pressure

 

Current Phase Thoughts

  • This is inteded to demonstrate the starting point for computer vision.
  • The focus is on fundamentals for shooting decisions, rebounding effort, and picks
  • Good and bad grades were subjectively decided and coaches need to give their definition
  • Grades can be team or individual, and rolled up to units
  • The Scorecard uses a simple +/- system
  • Picks were identified using mathematics and only for on ball screen.   There are probably many more picks than in this review.
  • The consumer grade camera loses players so the data is not perfect
  • Spacing needs better cameras but shows how the offense flows.

 

Potential Enhancement

  • Possession grade that incorporates all aspects of a possession
    • Offensive and defensive possessions
    • Starting at the outlet pass to the end of the possession
    • Include objectives of the coaching staff
      • picks (on ball & off ball)
      • passes
      • movement
      • rebound position, etc.
    • Rolled up to player and unit
