How Does the Ball Tracker Work in Golf?

Effective technology is essential in enhancing the viewing experience of golf tournaments. Using advanced ball tracking systems, such as Trackman, golfers and viewers can gain real-time insights. In this article, we will explore how these ball trackers function, with a focus on the Trackman and TopTracer systems.

Understanding the Trackman Technology

Trackman is one of the leading ball tracking technologies in golf. It operates based on doppler radar, a non-invasive technology that projects microwaves onto the golf ball to track its movement. When the ball reflects the microwaves back to the receiver, the changes in the wave pattern are measured, allowing for the calculation of various data points.

Step-by-Step Process:

A transmitter sends out microwaves to the golf ball. The ball reflects these microwaves back to the receiver. The changes in the wave pattern are measured and converted into real-time data points. These data points, including height, speed, and ball spin, are then visualized on the screen for the user to analyze.

For a more in-depth understanding, we'll discuss the signaling process in more detail.

How the Video Processing Equipment Recognizes the Ball

At the heart of the ball tracking system is the signal processing equipment. This equipment contains a special chip that identifies a small white dot moving rapidly relative to its surroundings. This white dot is recognized as the golf ball. The chip then processes the video frame, recognizing changes in pixel intensity to track the ball's movement.

Pixel-Based Tracking:

The technology relies on pixel-based tracking. In a typical golf tournament video frame, most content is slow-moving or remains stationary, such as grass, trees, and buildings. The pixels that make up the image are relatively constant, making it easier to spot rapid changes in pixel intensity, indicative of the golf ball's movement.

Here's a more technical breakdown:

Identify pixels that change color from one frame to the next, for example, green grass changing to white as the ball moves over it. Analyze the pattern of these changes to determine the ball's path. Use mathematical algorithms to extrapolate the ball's trajectory and display it in real-time.

TopTracer and Live Golf Coverage

TopTracer also plays a critical role in enhancing the live golf coverage experience. It uses advanced imaging software to detect the ball's motion against a stationary background. This software then superimposes the ball's trajectory on the live feed, providing viewers with a more engaging experience.

While TopTracer and Trackman have similar goals, they differ in their specific technologies:

Trackman relies heavily on doppler radar for accurate ball tracking. TopTracer utilizes advanced imaging techniques to detect the ball against a static background.

Regarding the delay in The Trackman system, it typically starts after the club head is out of view. This ensures that the system focuses solely on the ball's motion rather than the club head.

Conclusion

The ball tracking systems used in golf, such as Trackman and TopTracer, are remarkable technologies that enhance our understanding and enjoyment of the sport. By leveraging advanced radar and imaging technologies, these systems provide real-time data and visualizations that are invaluable to both golfers and viewers.
