Models for photogrammetric building reconstruction

Models for photogrammetric building reconstruction

The paper discusses the modeling necessary for recovering man made objects | in this case buildings | in complex scenes from digital imagery. The approach addresses all levels of image analysis for deriving semantically meaningful descriptions of the scene from the image, via the geometrical/physical model of the objects and their counterparts in the image. The central link between raster image...

Object-based Integration of Photogrammetric and LiDAR Data for Accurate Reconstruction and Visualization of Building Models

Automatic Correspondences for Photogrammetric Model Building

The problem of building geometric models has been a central application in photogrammetry. Our goal is to partially automate this process by finding the features necessary for computing the exterior orientation. This is done by robustly computing the fundamental matrix, and trilinear tensor for all images pairs and some image triples. The correspondences computed from this process are chained t...

3d Reconstruction of Building Models

This paper describes a knowledge-based approach to automatic 3D reconstruction of buildings from aerial imagery. The approach relies upon the use of 2D GIS map and knowledge about the imaging geometry and acquisition parameters. We show that by integrating knowledge from the images and the GIS map, the complexity of the building reconstruction process can be greatly reduced. In the first stage ...

Long Focal Length Imaging for Photogrammetric Reconstruction

The following paper describes a method to capture high quality image data for the use of photogrammetric reconstruction techniques. The main principle is to use long focal length to capture immense amount of spatial and radiometric detail. The method was tested at two mediaeval building sites, the Olavinlinna Castle in Savonlinna and the Church of the Holy Cross in Hattula. Long focal length is...
