Symmetry Calibration Issue about livescan3d HOT 4 OPEN

Hi Mike,

I'm not sure what you mean by "having the first kinect mirrored", could you include a screenshot?
I understand that you have two markers on the opposite sides of some object (a box for example). If that is the case, then the rotation of one of the markers should be all 0 while the other should have 180 rotation around the y axis. You mention that you did this for translation, but I imagine this is just an error in the description.

The z having no bearing on the calibration is surprising. Did you calibrate after changing the value of z or before? The changes will only take effect for calibrations done after the value was changed.

Best regards,

Thanks for the response! So I have attached two images. Those are the views I get when I do a circle around the subject. I expect to see his back from the 2nd Kinect when I go behind the subject, but I see the front again. I also recalibrated after changing z and no change, which seems to me that it’s a deeper core calibration issue.

This was the y value I changed to 180, the translation row. I changed orientation y to 180 but it did not seem to work. The second image is with 180 y on rotation. The z value for translation (thickness of box) was .3175 (since unit is meters). Other z is just 0. Sorry for the clipped image.

Hi,

Sorry for the delayed response. Changing y in translation to 180 just moves the point cloud 180 meters up i.e. out of the field of view. The second image you posted with rotation set to 180 actually seems ok other than the fact that the distance between the front and the back of the person might be too much, not sure from that angle.

Do remember that what you are seeing is a point cloud and that it does not have back side culling (since it is not a mesh). This means that you will see the front of a person if you look at it from behind, unless there is something occluding it.

Does that make sense?
