How to Detect Goal Keeper Dives in OpenField

What are Catapult Goal Keeping Analytics?

Catapult’s Goal Keeping Analytics use advanced algorithms to automatically detect goalkeeper-specific dive events and quantify key performance metrics for each dive.

There are two versions available:

Version 1 (GK.V1)

Uses the original detection algorithm.

Each dive is classified into combined metrics such as:

• IMA Dive Intensity Band
• Dive Direction (Right/Left)
• IMA Dive Return Band

Example output:

IMA Dive Intensity Band x, Right, Return Band y

Version 2 (GK.V2)

Uses a newer, more accurate detection algorithm.

Each dive is broken down into three intuitive metrics:

• Dive Load – intensity of the dive
• Time to Feet – time taken to return to upright position
• Dive Count – number of detected dives

Each metric is further divided into Bands associated to:

• Intensity of Dive Load
• Direction of Dive (Left, Centre, Right)
• Duration to return to an upright position (Time-to-feet)

Note: Version 2 is recommended for improved accuracy and clearer reporting.
