Rapid Graphical Registration for 3D Complex Objects for Construction Workspace Automation
نویسنده
چکیده
Although considerable achievement has been made to the development of methods of extracting 3D geometrical information of objects from a scene, there are still major difficulties to visualize complex objects into descriptive CAD models. This paper introduces a new framework for rapid 3D modeling for complex planar objects which would enable automated material handling and semiautomated equipment control, and could significantly improve safety by enhancing operator’s spatial perception of the workspace KEYWORD: construction automation, 3D, CAD, complex model, laser range finder
