View Full Version : How to reconstruct the position of the missed markers duringhuman motion capture

02-12-2007, 02:36 AM
Dear colleague,

The motion-capture systems (such as Vicon, Qualysis, and Motion Analysis, etc.) have being widely used in human movement analysis. It could be frequently encountered that some markers are missed for several consecutive frames during motion capture. Almost all commercial systems mentioned above have the function to fill the gap of the missed marker's trajectory by using cubic spline or linear interpolation. However, the accuracy is not high enough using this function. Sometime, the filled trajectory is totally wrong.

Does any one have same experience to solve this problem? Is there any reference which describes the reconstruction of the spatial trajectory of the missed marker?

Any comment will be sincerely appreciated.

Warm regards

Feng Yang
