Hi!

I am wondering, if there is some kind of best practice out there or someone could share her/his experience about how to best place the Kinect, Xtion or a similar device on a robot.

To be more specific, I am thinking about which viewing angle is necessary to get good results for object recognition, e.g. with objects on a table. Is there an optimal viewing angle - maybe 45 degrees?

I would be happy, if somebody doing table-top manipulation, e.g. with the PR2 + Kinect, could tell me about the viewing angles for which object recognition works well.

Thank you!

well, it all depends on the technique you use, it is that simple: template techniques like LINEMOD will need the same view points that you acquired during training, feature based ones can be a bit more robust to warping and so on.

Train your detector in angle/scale/illumination in the same way you will detect your object and accuracy will increase.
