Interactive Architectural Modeling from Point Clouds

In this work, we present an intuitive and interactive tool to model high quality 3D architectural objects starting from a MVS point cloud. Our implementation is inspired by [1] that describes the modeling system as well as the 3D reconstruction algorithm we use with some modification. We provide: • a simple mechanism to extract floor plans and profiles from a point cloud • an error computation between the modeled object and the point cloud • an easy way of using the pictures used to generate the MVS point cloud to improve the modeling An algorithm to merge two general events by automatically adjusting the profiles is also presented and finally, we show a texturing algorithm using the previously mentioned pictures.
