Abstract
We present an interactive reconstruction system based on space
carving. The user controls the camera and object positions and
their impact on the reconstruction is immediately displayed. The
flow of images is used first for silhouette carving, and then
representative images are stored in a hemispherical structure for
balanced color carving. Projected color points on the measured
background or on the object (acquired by structured light) allow for
automatic and adapted calibration of the camera. The octree object
representation is central to our space carving algorithm: voxels are
efficiently carved out at their largest size, images are treated at
their appropriate level, and 3D regions are subdivided only when
necessary. We conclude by analyzing our results and by discussing our
acquired experience.
