What Khel.ai Does for Volleyball

Built on the sport, not bolted on to it

01

Rotation and libero compliance

Six positions are held from the serve order, so overlap faults, illegal back-row attacks and libero replacements surface before the rally is scored.

  • Overlap fault alerts
  • Libero replacement log
  • Back-row attack line checks
  • Serve order verification
02

Serve and pass ratings

Every serve is typed as jump, jump float or standing float, then paired with the passer, the contact zone and a 0 to 3 rating on the first-contact pass.

  • Serve type and zone maps
  • Pass rating per receiver
  • Ace and error breakdown
  • Receive seam heat maps
03

Set, spike and block phases

Set tempo, attack angle and swing speed are logged per hitter, with block touches, penetration and dig conversion attached to the same rally record.

  • Set tempo and location
  • Hitting efficiency per swing
  • Block touch detection
  • Dig and coverage mapping
04

Indoor and beach models

The same pipeline runs on the 18 by 9 m indoor court and the 16 by 8 m sand court, with wind drift, sun glare and two-player coverage handled by the beach model.

  • Sand court calibration
  • Wind drift compensation
  • Two-player rally tracking
  • Hand signal capture

Capture to Insight

How a volleyball fixture becomes data you can act on

  1. 1

    Rig

    Six calibrated cameras cover both antennae, the end lines and the net band, from a school hall balcony to a full show court.

  2. 2

    Track

    Ball, twelve players and the libero are followed through serve, receive, set, attack, block and dig with nobody tagging from the bench.

  3. 3

    Classify

    Each contact is labelled by skill, tempo, zone and outcome, then joined to the rotation on court so sideout and transition splits build themselves.

  4. 4

    Deliver

    Rotation sheets reach the coach's tablet between rallies, while the challenge feed and the broadcast overlays draw on the same rally record.

Volleyball Questions

What federations, clubs and academies ask us about volleyball

It does. Ball position is triangulated to within 11 mm at the antennae and sidelines, and block touches are resolved by fusing 200 fps vision with net-band audio. Verdicts return to the second referee in about three and a half seconds.
