Automatic Fusion of Digital Images and Laser Scanner Data for Heritage Preservation
نویسندگان
چکیده
This paper presents an automatic procedure for combining digital images and laser scanner data in order to have a full representation of a scene. In particular, this procedure will serve photogrammetric close range applications such as 3D digital preservation and documentation of cultural heritages by generating highly virtual reality models. Our method is based on a bundle adjustment for the orientation estimation of generated images from laser data and camera images by means of an optimized Structure and Motion reconstruction method. The output provides accurate control information for target free registering multiple laser scans and absolute camera orientations. The proposed pipeline was tested on a real case study and experimental results are shown to demonstrate the effectiveness of the presented approach.

Digital Archiving in Cultural Heritage Preservation
This project presents a digitizing process of 3D laser scanner for culture heritage. The experimental records are mainly for systematic 3D model reconstruction and digital archiving of historical scenes. The procedures of digital heritage are 3D data acquisition, 3D modelling and web-based representation which demonstrate the reconstructed results and the application of virtual scene.

متن کاملFusing Airborne Laser Scanner Data and Aerial Imagery for the Automatic Extraction of Buildings in Densely Built-up Areas
Using airborne laser scanner data, buildings can be detected automatically, and their roof shapes can be reconstructed. The success rate of building detection and the level of detail of the resulting building models depend on the resolution of the laser scanner data, which is still lower than the resolution of aerial imagery. Building extraction from aerial images alone is difficult because of ...
