To gain accurate measurements, the distance from the object to the camera has to be known. Several tricks can be used to resolve this, but since Kinect has a measurement laser it may have a lot of promise for automation. Do you know how accurately distance can be measured with the Kinect laser?
If you need any help with Labview Image analysis - let me know. I will be glad to help.

Hi Boris,

Thank you! The accuracy is 11bits of depth and converted into a standard measurement size is approximately 10 cm off at 4 m away, and less than 2 cm off within 2.5 m. However there is a minimum distance also needed for the Kinect, roughly 18 inches. There is lots of information here on it: http://openkinect.org/wiki/Imaging_Information There is talk about Microsoft using a higher resolution IR Projector to achieve better accuracy.

I'll definitely let you know if there's any questions I have with the image analysis

Regards,
Ryan Gordon
