2D and 3D motion analysis

Motion analysis is used in several fields of applications: In sports science, clinical gait analysis, physiotherapy and other medical sections.

Typical motion analysis measurements acquire kinematic and dynamic data.

Optical systems

Most motion analysis applications need optical information to determine the movement or to visualize the resulting diagnosis.

high-speed camera for motion analysis While clinical gait analysis handles slow movements most other activities require a higher resolution in time. High-speed video cameras with 100, 300 or even more than 1000 frames per second can be used to gain high accuracy.

2D motion analysis is a subset of 3D motion analysis and requires only one camera, while 3D measurements require at least two cameras from different perspectives.

Analog data acquisition

Kinematic and dynamic data is usually acquired with analog digital converter hardware where sensors for forces, pressure, acceleration or angular movement can be connected.

Static vs. dynamic motion analysis

For simple motion analysis applications it is often sufficient to measure positions, distances or angles at specific points in time (events). For these cases a static kinematic measurement will be a quick and easy solution.

kinematic motion analyis

Other, more complex applications, require certain values or signals to be measured continuously in order to plot graphs or other diagrams (dynamic kinematic measurement).
