We give a method for improving the resolution of surfaces captured with a laser range scanner by combining
many very similar scans. This idea is an application of the 2D image processing technique known as super-
resolution. The input lower-resolution scans are each randomly shifted, so that each one contributes slightly
different information to the final model. Noise is reduced by averaging the input scans.
Categories and Subject Descriptors (according to ACM CCS): I.3.3 [Computer Graphics]: Surface Acquisition
Laser range scanners are used to capture the geometry of
three-dimensional objects. They are used for reverse engi-
neering manufactured objects, and for digitizing objects of
scientific, artistic or historical importance for archiving and
analysis. Like all physical measurement devices, laser range
scanners have limitations, including noise and limits on res-
