I recommend skipping intrinsic calibration and per-pixel depth calibration on the first installation. The factory-supplied calibration downloaded in step 6 of the installation instructions is usually fine. If the alignment is more than a few millimeters off after projector calibration, I recommend doing the per-pixel calibration first. It’s pretty simple and the biggest cause of errors.

But to answer your question: before aligning a grid select “Average Frames” from RawKinectViewer’s main menu and wait until the depth image no longer changes. Then line up the grids in the depth and color images and select a tie point. To go to the next tie point, un-check “Average Frames” again, move the camera, and repeat.
