sparse3dscan_400px

Real-time 3D point cloud reconstruction from video at 25 fps on CPU for mobile mapping.

huns_400px

Hierarchical Unregularized Superpixel (HUNS) algorithm outperforming methods like SLIC, ERS or SEEDS.

sfmplanes_400px

Image-based modelling by combining sparse 3D points and multi-view plane segmentation over superpixels.

spmesh_400px

Compact surface mesh reconstruction from images via sparse 3D points and vertex depth optimization.

spdem_400px

Efficient conversion of dense height or depth maps into a compact mesh  via fast piecewise-planar partitioning.

fusion_400px

Efficient surface reconstruction fusing street-side and point clouds via ray shooting into a tetrahedralization.

airborne_semantic_400px

Segmentation of airborne 3D models into buildings, vegetation, ground, water in spite of geometric defects.

texturing_400px

Fast multi-view texturing of urban surface models jointly from airborne and street-side data.

facade_semantic_400px
