Reconstruction was done in the following steps:
Corresponding points were marked by mouse in 10 sequence images.
Polygons were marked, each in one image.
Projective reconstruction via trifocal tensors in CAKE configurations was

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.

Three images from the input sequence:
Two views on the reconstructed model:
The experiment was done using CORRGUI software system developed in CMP
by T. Pajdla, T. Werner, J. Burianek, J. Cernik.
