High Speed Motion Analysis

We use motion analysis tools to determine the velocity, rotation and energy of natural rock falls. After a high speed video is captured, we use the motion analysis software to break down each frame and track the change in position. We can track multiple markers on a test block or natural rock as they are dropped from a high slope. Motion analysis has facilitated us in quantifying the change in energy during a rock fall and been used to better contain rock falls and construct rock fall protections.

We strive to achieve a thorough understanding of rock fall trajectories and improving protection structures. Please contact us if you have research you would like to share with us.
