4. Q When try to take a calibration snapshot get a message saying Invalid Calibration Pattern What does this mean A This message is displayed when the software is unable to locate the calibration pattern in the current video frame Your video may be too dark your calibration pattern may be too far away or the pattern is tilted too much away from the camera This message will also be displayed if you are using an incorrect calibration pattern Q Why are my markers in the right image numbered differently than the markers in the left image A This is caused by incorrect marker matching Check to make sure that the left and right images have the same number of marker detections If not try adjusting the marker parameter sliders when initializing the markers Delete unwanted markers using the marker deletion tool If this does not help try selecting another video frame and re initialize your markers If you are still unable to match the markers correctly you may be using a poorly calibrated camera setup Recalibrating your camera setup should fix this Q Some markers are surrounded by a blue box others by a green box What does this mean A Green boxes indicate correct stereo matches The blue boxes indicate a possible stereo mismatch between your left and right images Mismatches may be due to different left and right marker counts or poor camera calibration Q Why do need to filter my data and what filter should use A
5. Filtering is required when your motion appears jittery or jumpy in the Motion Analyzer The Kalman filter is recommended over the LPF for most applications Q How do I use the Global Motion Stabilization feature A When you capture your moving subject place three additional markers on a stable area on your subject for facial motion capture you can use the forehead The markers should be arranged such that they form the three corners of a triangle Later when you export your data in MYCAP Studio select these three markers as your stabilization markers Your data will then be stabilized relative to these three markers The stabilized output has a suffix stab appended to the filename Q When import my motion capture data into my 3d application some of the points are not correctly positioned A This may be due to a poorly calibrated camera pair Also check to make sure the marker numbering in the left image is the same as in the right image during marker identification Please refer to the section Capturing Motion for guidelines on how to capture motion Q Why won t all my markers be detected A When recording video always make sure your markers are much brighter than your subject This will greatly improve detection In some situations markers may be too dark to detect correctly In this case you can try to adjust the brightness threshold If your markers are too close together they will also not be detected Reducing the wi
