The Office of the Chief Architect established the National 3D-4D-BIM Program in 2003. Since then, over 70 capital projects have been initiated throughout the U.S. using an array of 3D, 4D and Building Information Modeling (BIM) technologies in support of GSA business. The GSA is committed to a strategic and incremental adoption of 3D, 4D and BIM. One of the important enabling technologies in ...

There are few steps in building photo-realistic 3D indoor models: (a) localize the backpack and hence all the sensors that are rigidly mounted on it; (b) construct a 3D point cloud using the laser scanners and the localization results from a; (c) reconstruct a surface to the point cloud by either plane fitting, or other algorithms (d) texture map the final results. There are a number of mini ...
