A few days ago, LightBuzz released our universal body-tracking SDK. The new SDK allows developers to create amazing motion capture applications for Windows and iOS with just a few lines of code.

Human Body Tracking

The new Body Tracking software is a combination of Artificial Intelligence, Machine Learning, and Human Biomechanics. Our engineers, along with sports scientists, have crafted a state-of-the-art module that allows computers to recognize 21 skeleton joints in the 2D and 3D space. This way, you can develop smart applications in the areas of sports, healthcare, entertainment, and even the military.

Supported Cameras

Currently, you can use any video camera to track the human body joints of multiple people. Integrated laptop cameras? Yes! External Logitech webcams? Sure! iPhone front & rear cameras? Absolutely! We even support the latest Intel RealSense and iOS LiDAR cameras for advanced 3D body tracking. Oh, and did I mention that you can process existing MP4, AVI, or MOV video files?

Supported joints

The LightBuzz SDK can track up to 20 people on a single frame. That’s stunning. In the image below, you can see the exact joints the software detects.

What about face masks?

During the recent COVID-19 pandemic, the use of face masks has become part of our daily lives. Face masks filter the air we breathe, and protect ourselves and those around us from evil viruses. Some people even exercise using masks! It seems they are here to stay. So, we have adjusted our Body Tracking SDK to estimate the position of the eyes, ears, and nose when someone wears a face mask.

What about human-like creatures?

Today is the global Star Wars day. So, I had an insane idea: what if I tinkered the SDK a bit to recognize my favorite Star Wars heroes? OK, detecting the joints of Luke Skywalker would be trivial, but what about the not-so-human characters? It turns out it’s doing pretty fine detecting Master Jedi Yoda and some Stormtroopers.
