document: A framework for rapid local area modeling for construction automation Rapid 3D positioning and modeling in construction can be used to more effectively plan , visualize , and communicate operations before execution . It can also help to optimize equipment operations , significantly improve safety , and enhance a remote operator 's spatial perception of the workspace . A new framework for rapid local area sensing and 3D modeling for better planning and control of construction equipment operation is described and demonstrated . By combining human-assisted graphical workspace modeling with pre-stored Computer-Aided Design -LRB- CAD -RRB- models and simple sensors -LRB- such as single-axis laser rangefinders and remote video cameras -RRB- , modeling time can be significantly reduced while potentially increasing modeling accuracy
