Automated Facade Reconstruction         

[Frueh and Zakhor, 3DPVT 2002]



Video clips


These video clips, created by John Flynn, illustrate our facade reconstruction steps:



1. Path segmentation & depth image generation


Subdividing driven path into quasi-linear segments and convert to depth image.




2. Foreground/background separation


Based on histogram analysis, foreground objects (cars, trees, etc.) are separated from the background (facades)




3. Facade processing and hole filling


Removing erroneous scan points and filling holes in the facades. 


4. Texture mapping


Using camera images to texture-map the facades. Occlusions and foreground objects in the images are considered.
