4DSwing is the most advanced golf swing analyzator ever developed. It measures facts about the body and club movement during a golf swing, without any sensors attached to the body nor club. The system uses machine vision instead. The swing results can be analyzed and advancements measured with a special software that works over the Internet. This makes it possible to get comments from a coach or friends that access the swing data from any distance. The idea of 4DSwing is to help golfers identify the strengths and weaknesses of their swing so that they can be influenced.

The 4DSwing hardware system consists of 6-8 high-speed cameras, LED lighting system and touch-screen computer. The solution converts the video data of the cameras into an accurate 3D model. The reproduction of the swing as a 3D model and the real video images can be viewed simultaneously with the numerical and graphical swing data on the GUI application. Previous swings can be compared and also professional swings can be taken as a reference point.

We also created a mobile viewer for the 4DSwing software for Android and Maemo platforms.  This enables showing your swing videos to your friends on the move.

The software user interface was built with Flash/Flex technology. The background integrations were done with Java-EE and different Java libraries.  The mobile software was built with Qt, C++, SOAP and Java. The database is based on PostgreSQL and JPA.
