DETECTING OPENINGS FOR INDOOR/OUTDOOR REGISTRATION

Abstract. Indoor/Outdoor modeling of buildings is an important issue in the field building life cycle management. It seen as a joint process where two aspects collaborate to take advantage their semantic and geometric complementary. This global approach will allow more complete, correct, precise coherent reconstruction . The first such thus precisely register this data. lack overlap between indoor outdoor data most encountered obstacle, so when both sets are acquired separately using different types sensors. As opening façade unique common entity that can be from inside outside, it help registration point clouds. So must automatically, accurately efficiently extracted. In paper,we start by proposing very efficient algorithm detect openings with great precision scans. Afterwards, we integrate them framework. defined rectangular shape composed four segments, horizontal vertical, write our problem minimization robust distance segment propose minimize RANSAC paradigm.
