An object recognition and positioning system that employs real-time location, a robotic total station, and a building information model in a single, transparent system that delivers object positioning, recognition, tracking, and operation.

Object recognition and tracking using a real-time robotic total station and building information modeling

A positioning system that combines the use of real-time location system and a robotic total station into a single, transparent hybrid positioning system to locate one or multiple targets by one or multiple users.

Hybrid positioning system using a real-time location system and robotic total station

A method and apparatus utilizing a high-precision GNSS receiver, an EDM, and an optical camera in combination for making accurate measurements of multiple remote points. The accurate measurement of a plurality of remote points is facilitated by integrating a high-precision GNSS receiver, an EDM and an optical camera such that their combined physical location and orientation can be measured and known, and allowing for a single calibration thereof. The integration of the high-precision GNSS receiver, an EDM, and an optical camera may take various forms such as a single, integrated device, or individual devices assembled together on a surveying pole, for example. The integrated device may also include one or more sensors such as an inclination sensor and an inertial measurement unit.

Enhanced remote surveying systems and methods

A method and a system in which an image of an object having a tip end and a plurality of markings disposed on an outer surface is acquired, a distance between the measurement system and each of the plurality of markings and a plurality of angles at which the object is positioned in the three-dimensional space are determined, a three-dimensional vector of the object is determined based on the distance between the measurement system and each of the plurality of markings and based on the plurality of angles at which the object is positioned in the three-dimensional space, and a position of the tip end in the three-dimensional space is determined based on the distance to each of the plurality of markings and based on the three-dimensional vector of the object.

Method and system to identify a position of a measurement pole

An augmented image is generated by capturing a visual image of a site with a digital camera, generating a virtual image or associated information from a digital model of the site, and superimposing the virtual image or associated information on the visual image. To register the digital model with the visual image, a sensor pole is introduced into the field of view, and a combined visual image of the site and an optical target on the sensor pole is captured. The position and orientation of the sensor pole with respect to the site reference frame are measured by sensors mounted on the sensor pole; the position and orientation of the digital camera with respect to the sensor pole are calculated from image analysis of the optical target on the sensor pole; and the position and orientation of the digital camera with respect to the site reference frame are calculated.
