Qualisys AIM Model improvement

[Serge Yakushevsky]

Hello,
In ourlaboratory we work with Qualisys (QTM system).
My question:how can I improve AIM model to reduce manual corrections of unlabeled markers?At the beginning of the measurements, I define AIM model on dynamic motion fileand then just adds new measurement to existing AIM model, exists other way ortechnic for resolving this problem?

Best Regards,

Hi Yakushevsky

The general advice is to include as great a range of movement as possible in a trial including movement similar to that you wish to capture. I get good results from recording 30 seconds of general movement at the same frame rate as the trials I wished to capture. I have yet to test if including motion throughout the capture volume improves the AIM prediction, perhaps someone else may comment on this.

Additionally, you may wish to consider the following:
Include data from a number of subjects if relevant.
Don't add data to the AIM model from poor quality captures (low percentage marker visibility, even if it's a low number of markers).
Make sure QTM is up to date as Qualisys is continually improving AIM.

Hope this is helpful.
