RECX is a software system, developed in CMP, which allows manual marking points of interest/correspondences/polygons in an image sequence, and 3D reconstruction.
See research report Werner, Tomas; Pajdla, Tomas; Urban, Martin. REC3D: Toolbox for 3D Reconstruction
from Uncalibrated 2D Views. [tr99-4.ps.gz,
PostScript].
Reconstruction was done in the following steps:
- Corresponding points were marked by mouse in three sequence images.
- Polygons were marked, each in one image.
- Projective reconstruction via trifocal tensor was done.
- Proj. rec. was upgraded to a Euclidean reconstruction using Pollefeys et. al algorithm (ICCV98).
- VRML1 model extracted. Texture warped from the marked polygons.
Two images from the sequence (total 7 images):
Reconstructed scene:
VRML1 model [11kB wireframe, 130kB textured]
(The texture is warped via affine transformation, supported by VRML, which causes its distortion - see e.g. the front wall.)
more advanced VRML1 model [310kB wireframe, 1MB textured]
(The texture is warped correctly due to approximating planar patches by small triangles.)
