Projective Reconstruction Based on Cake Configuration with Panoramic Reference View
Center for Machine Perception
Czech Technical University,
In this experiment, an image from a panoramic
catadioptric camera was used as reference
view. The other seven views were taken using a standard digital
photo-camera. The resolution of the catadioptric camera was 1000x1000 pixels
and of the photo-camera 1200x1600 pixels.
Reconstruction was done in the following steps:
Corresponding points were marked by a mouse.
Polygons were marked, each in one image.
Projective reconstruction via trifocal tensors in "unclosed" CAKE configurations
was done (See
Tech. report Urban-TR7-99.ps.gz)
Proj. rec. was upgraded to a Euclidean reconstruction by selecting 3D Euclidean
coordinates of 5 points.
VRML1 model extracted. Texture warped from the marked polygons. Warping
is done by affine transformation (supported by VRML) instead of projective
one, which is not entirely correct.

The experiment was done using CORRGUI software system developed in CMP
