Computer Vision Lab

Slogan goes here…

Located right next to the cereneo neurorehabilitation clinic Hertenstein, the Computer Vision Lab is equipped with a variety of state of the art sensor systems for capturing movement data. This includes a marker-based optical motion capture system, several RGB cameras that form a markerless, computer-vision-based motion capture setup, a Kinect camera, and an Inertial Measurement Units system.
The lab mainly focuses on analyzing movements of the upper limbs. It can conduct standardized clinical tests like the ARAT, Drinking Task, or Box and Block Test, using the preferred sensor systems to gather data.
Researchers in the lab are working on developing and validating new motion capturing systems and algorithms. The use of more affordable sensors in these new systems could lead to their broader use in everyday clinical settings. Recording movements with different sensor systems at the same time allows for highly accurate movement analysis and is crucial for validating the new sensor systems and algorithms developed in the lab.

Key Technologies

Our lab features a state-of-the-art marker-based optical motion capture system. Renowned for its precision, this system tracks movements accurately using infrared-reflective markers placed on the subject. It’s highly valued in kinematic studies for its reliability and exactness in capturing detailed motion data and is thus considered the gold standard of motion capture.

Markerless Motion Capture is an emerging new technology that uses computer vision for key point detection and does thus not require infrared markers and infrared cameras but relies on simple RGB cameras. In the lab markerless motion capture can be conducted with up to 10 RGB cameras.

The Kinect Camera System in our lab is a versatile tool for motion capture, utilizing depth sensing and RGB camera technology. This system captures human motion and gestures in 3D space without the need for wearable markers. It’s particularly useful for interactive applications and quick movement analysis in a less controlled environment.

Our lab employs Inertial Measurement Units (IMUs) for advanced motion capture. These small, wearable sensors detect movement through detecting acceleration and rotational changes, providing a versatile, markerless method for analyzing motion. Ideal for tracking dynamic movements in various environments, IMUs offer a practical solution for real-world motion analysis.
