LASER SCAN RE-ENGINEERING OF 3D CAD MODELS

摘要

A three-dimensional CAD model of a facility, city or multi-asset grouping is re-built from laser scan data of the facility/city/multi-asset grouping. Through a rules-based analysis, CAD model objects are identified in the laser scan data. The rules map laser scan data to CAD model objects based on shape, size and/or sequence of connection of objects in the facility/city/multi-asset grouping. Design logic of equipment and process facilities are also utilized by the rules.
