Image-to-laserscan registration calibrates an RGB image to a laser-scan reflectance signal, which is needed to colorize a laser-scanned 3D environment. It works by identifying common elements, called features, in both the image and the scan, and matching them. The features must remain similar enough to match after perspective changes, distortion and noise.
Matching becomes particularly difficult when the image and the scan have different intensity modalities, because descriptors must be found that are similar across two very different representations.
In this project we developed a completely new method for calibrating an RGB image to a laser-scanned environment for Autodesk.
