Client Challenge

  • Modern sports training and entertainment facilities are rapidly evolving into high-density, multi-bay environments. In the client’s facility, multiple players can simultaneously play cricket and golf across different bays, often launching balls at the same time. This creates a highly dynamic environment where several balls are in motion concurrently, each traveling at high speed and sometimes crossing paths or overlapping visually.
  • Accurately tracking every individual ball in such conditions is extremely complex. Each ball must be associated with the correct player and bay, while maintaining precise measurement of its movement throughout the entire flight. The client required a real-time tracking system capable of generating detailed performance data instantly, without confusion or identity switching.

The system was expected to capture and report the following metrics for every ball hit:

  • Full 3D flight trajectory
  • Launch position, launch angle, and launch velocity
  • Launch time and landing time
  • Landing position and landing velocity
  • Bay number and player association

Traditional single-camera systems lacked reliable depth perception, while sensor-based approaches introduced high operational complexity and ongoing maintenance. The client needed a scalable, accurate, and future-ready solution that could operate reliably in real-world conditions.

Katomaran`s Solution

  • Katomaran Technologies designed and implemented a real-time, stereo vision–based multi-ball tracking system tailored for complex sports environments. The solution is entirely vision-driven and does not require physical sensors, tagged balls, or wearable devices.
  • The system uses synchronized high-speed stereo cameras to reconstruct accurate 3D ball movement from the moment of launch until landing. This depth-aware approach allows the platform to separate and track multiple balls simultaneously, even when they overlap visually or cross paths mid-air. Advanced computer vision algorithms combined with physics-based motion models ensure stable tracking, precise measurements, and consistent performance across multiple bays.
  • The solution was architected as a modular platform, enabling seamless integration with scoring engines, gameplay systems, and analytics platforms. With sub-200 millisecond latency, the system delivers real-time intelligence without interrupting the player experience.

How It Works

Player Action

Ball Hit from Bay

A player hits a cricket or golf ball from an assigned bay, initiating the tracking process.

Stereo Camera Capture

Synchronized High-Speed Recording

Dual high-speed cameras capture the ball simultaneously from two angles with frame-level synchronization.

Stereo Depth Reconstruction

True 3D Position Calculation

Stereo triangulation computes the ball’s accurate 3D position at every moment of flight.

Ball Detection & ID Assignment

Multi-Ball Tracking with Persistent IDs

Each detected ball is assigned a unique ID to preserve identity across the entire trajectory.

Physics-Based Analytics
