Disclosed is a method for 3D building extraction, comprising: extracting building footprints from one or more stereo images for a building; determining, from rational polynomial coefficient of the stereo images, first height estimation of the extracted building footprints; obtaining, from multi-temporal SAR images for the building, scatters with stable attributes; determining second height estimation for the determined scatters; and combining the first height estimation and the second height estimation to generate a fused height for each of the extracted building footprints.

3D building extraction apparatus, method and system

A computer-implemented method for modeling an orthopedic cast, including scanning an injured limb to extract raw body data; determining, from the extracted raw body data, a target portion data of the injured limb, the determined data representing a fine cast surface for the orthopedic cast; patterning the fine cast surface to form a ventilation structure and a blank area thereon; forming an opening gap on the blank area for assembling and disassembling the orthopedic cast; and offsetting the cast surface in parallel to thicken the orthopedic cast.
