01
Fixed cameras at the court
Calibrated cameras mount around the court boundary and stay put — no operator, no tracking rig to aim.
Launching Q1 2027
Line calls, verified.
Frame-by-frame bounce verification, confirmed against real camera footage.
Mission
OrthoTennis exists to make accurate line calling accessible to every court — from local clubs to serious competition. Every call is grounded in camera footage of exactly where the ball landed, reviewed frame by frame on the court it was played on.
How it works
Three steps, one source of truth
02
Every bounce verified frame by frame
The ball is tracked in 3D across all cameras; each bounce is verified against the actual court geometry captured on camera.
03
The call is delivered instantly
A clear audio tone and on-screen readout announce the call the moment it's verified — no delay, no ambiguity.
Two modes
Call every ball, or just the close ones
Challenge mode
Players opt in
Line judges and umpires keep the call. Players challenge only the shots they want checked, and get a frame-verified answer in seconds.
