Markerless motion capture: the challenge of accuracy in capturing animal motions through model based approaches

摘要

In the paper the application of model based markerless motion capture technology to general environment and quadrupeds is presented. Some of the authors' recent results are discussed together with the open challenges related to the capture of animal motion. Despite its very recent history, markerless motion capture represents already both a valuable alternative to marker based approaches and in some circumstances the only valuable solution. One of these cases is animal capture where the positioning of markers on the animal is very challenging when possible at all. An example of markerless tracking of animal motion is shown together with a virtual validation to provide quantitative evidence of the robustness and accuracy of the presented method.
