Unsurprisingly, gross physical deformation of an RGBD sensor body will produce changes in the distortion pattern of the sensor. Surprisingly, you can cause this yourself quite easily without being aware of it.

We ran in to this when mounting an Asus Xtion Pro Live using velcro cinch straps around the sensor body. Pulling to hand tightness easily causes noticeable changes in the distortion pattern. If you’re trying to calibrate a sensor using our CLAMS work, this can really mess you up.

Here are some examples showing the change in the raw sensor output when tightening vs loosening the straps. Mount your sensors with care!
