The present invention provides Augmented Virtual Models accessible via Orienteering using a smart device. The smart device is operative to identify a position within a building and use fine-grain location monitoring to guide a user to a desired location. Upon reaching the desired location, the user can point the smart device at a wall or component and learn, query, or supplement technical details and other information about the wall or component. Technical details and other information are stored in an augmented virtual model of the building.

Disclosed herein are techniques of geo-location for building sites including: providing means for determining a precise position; providing an application; starting the application; providing at least one feature option to the user of the application, the at least one feature option including at least one option that uses the precise position; acting upon at least one feature action on behalf of the user, the at least one feature action including at least one action that uses the at least one feature option; interacting with a 3D end point on the basis of the at least one feature action; and providing a final output that takes into account the interaction with the 3D end point. Users are enabled to precisely position building information that specifies precise construction deficiencies of a building site in a 3D model and to address those deficiencies during construction.

A tool within a manufacturing environment is located using a macro position locator to form an approximate location. A refined location is identified using the approximate location, a retro reflective target attached to the tool, and a laser tracking system.

A system and method for maintaining a laser impinging on a laser detector assembly includes determining a location of the laser from a rotating laser transmitter impinging on a laser sensor. A current position of the laser sensor along a mast of the laser detector assembly is determined and a new position for the laser sensor along the mast is determined based on the location of the laser impinging on the laser sensor and a current position of the laser sensor. The laser sensor is then moved to the new position. The system and method provide an effectively long working range of the laser detector assembly by moving the laser sensor along the mast of the laser detector assembly. An inertial measurement unit is used to calculate position information in the period between laser strikes.

A method for determining an elevation of a laser detector assembly includes calculating an estimated elevation of a laser detector assembly based on data from an inertial measurement unit and a detected laser strike. The estimated elevation is then output. A detected elevation of the laser detector assembly is calculated based on the detected laser strike and the detected elevation is output in response to the detected laser strike. The estimated elevation is calculated and output between outputs of detected elevations.

Described examples include a system for tracking a construction vehicle at a construction site. The system includes a Bluetooth receiver located at the construction site for receiving a unique identifier code transmitted by a Bluetooth beacon mounted on a construction vehicle, and the Bluetooth receiver is further configured to communicate the unique identifier code to a remote computer over a communications interface.
