Abstract

Range scans captured by laser scanners are an important source of data in attempts to capture and preserve heritage sites. Unfortunately this data almost always contains unwanted sample points, arising from people, trees and cars as well as scanner artefacts. Removing this data - 'cleaning' the scans - is generally a time consuming and labour intensive process.
In this talk I will highlight recent work with grad students to address the issue of semi-automating the process of range scan cleaning. I will also talk briefly about the work that we have started with collaborators here at CNR, with the aim of learning some kind of description of the data that is typically discarded.
