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
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.
