Explanation

If the coordinate system is out of place in one camera view, but is positioned and oriented as expected in the remainder of the views, it is likely that the position of the single camera changed between the recording of the calibration trial and the loaded movement trial. The camera view may have been intentionally changed, as in the case of adjusting a camera view to better capture the volume, or it may have been accidentally changed, in the case of a tripod being bumped by a passerby.

Possible Solutions

  1. Use a different calibration from the same session.

If multiple calibration trials were recorded during the data collection, try loading one of the other calibration files. If any of the other calibrations were recorded after the camera was moved, they should be able to properly calibrate the camera system. This is the best possible solution, and follows our recommendation to record at least two calibration trials per data collection (one at the start, one at the end).

  1. If possible, collect a new calibration trial.

If the cameras have not been moved since the movement trial was recorded, the next best solution is to record a new calibration trial with the cameras in their current position and orientation. This calibration trial can then be processed and assigned to the movement trial, allowing the camera system to be calibrated properly.

  1. Exclude the moved camera view.

If it is no longer possible to record an additional calibration trial (i.e. the camera system has been taken down), the camera that was moved can be excluded from the analysis using the tool under the Tools dropdown menu. Provided that the camera system consists of at least seven cameras and only one camera was moved, this will allow the movement trial to be processed using all properly calibrated camera views, preventing a total loss of the trial. Be sure to use the Toggle Views tool before running the analysis in order to exclude the affected camera view.
