Photorealistic scene reconstruction by voxel coloring Abstract: A novel scene reconstruction technique is presented, different from previous approaches in its ability to cope with large changes in visibility and its modeling of intrinsic scene color and texture information.

Aug 20, 1998 · We are developing a new approach called Voxel Coloring that reconstructs the "color" (radiance) at surface points in an unknown scene. Initially, we assume a static scene containing Lambertian surfaces under fixed illumination so the radiance from a scene point can be described simply by a scalar value, which we call color .

In this research we explore three methods of enhancing the performance of the voxel coloring reconstruction method. The first approach uses texture mapping to leverage hardware acceleration. The second approach uses spatial coherence and a coarse-to-fine strategy to focus computation on the filled parts of scene space.

As a solution, we present a voxel coloring technique that traverses a discretized 3D space in “depth- order” to identify voxels that have a unique coloring, con- stant across all possible interpretations of the scene. This approach has several advantages over existing stereo and structure-from-motionapproaches to scene reconstruction.

Jun 17, 1997 · A new algorithm that extends Seitz and Dyer's Voxel Coloring algorithm for reconstructing a voxelized representation of 3D object from a series of images, and a different search method that traverses the voxels along the projection rays of the images.

Nov 16, 1999 · The method avoids image correspondence problems by working in a discretized scene space whose voxels are traversed in a fixed visibility ordering. This strategy takes full account of occlusions and allows the input cameras to be far apart and widely distributed about the environment.
