|Automated Facade Reconstruction|
[Frueh and Zakhor, 3DPVT 2002]
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.
