They do have noise, but we are talking about milimeter to centimeter scale (accuracy is < 2cm). So a grown up person is roughly 2 orders of magnitude bigger than the accuracy of the scanner. To give an example how big (or small) this noise would have been in this situation I did a very simple virtual scan of a person with a bicycle at a distance of 15 meters [1] It was scanned with a virtual scanner inside our sensor simulation software, so this is not the real data and should be taken with a grain of salt.
