  • Patent number: 10347008
    Abstract: A camera is oriented at a workspace by comparing a three-dimensional model of the workspace to an image. A user provides an initial estimation of camera location. A feature of the three-dimensional model is projected onto the image. The feature of the three-dimensional model is compared to a corresponding feature in the image. A position and orientation of the camera are calculated by comparing the feature of the three-dimensional model the corresponding feature in the image.

  • Publication number: 20190004619
    Abstract: A system and method for determining a position and orientation (e.g., pose) of a rigid body is disclosed. The rigid body may be a position enabled projector, a surveying rod, a power tool, a drill robot, etc., in a given space. The position of the rigid body is specified by a set of three coordinates and the orientation is specified by a set of three angles. As such, based on these six values, the position and orientation of the rigid body can be determined.

  • Patent number: 9879994
    Abstract: A method for locating a position determining device in an interior construction site of a building to provide line-of-sight access to a plurality of construction points in the interior construction site, includes accessing a three-dimensional model of the site by a computer system, the model including coordinates of construction points in the site to be located with a position determining device. The method further includes determining a location for placing a position determining device by the computer system, in which no obstructions at the site preclude line-of-sight access by the position determining device to the plurality of construction points. The method may further include receiving spatial data by the computer system, and deriving the three dimensional model by the computer system based upon the spatial data. The position determining device may comprise a robotic total station or other such device. The method is implemented on a computer system.

  • Patent number: 9760078
    Abstract: A system for assisting in the use by an operator of the operating element of a tool at desired locations at a worksite, includes a stationary control and a position sensor secured to the tool. The stationary control is located at the worksite, and has data stored therein specifying one or more desired locations for operation of the operating element of the tool at the worksite. A position sensor is mounted on the tool. The position sensor determines the position of the operating element of the tool. The position sensor includes a communication device for communicating with said stationary control, a sensor for determining its relative position with respect to said stationary control, and a display for providing indications to the user of the tool of the desired location for the operating element of the tool and of the actual location of the operating element of the tool.

  • Patent number: 9585598
    Abstract: A system for determining the dimensional coordinates of a point of interest in a work space, includes a plurality of fixed-position ranging radios, located at known positions in the work space, and a wand having a first end configured for indicating a point of interest. A pair of ranging radios are mounted on the wand. A measurement circuit, responsive to the pair of ranging radios, determines the position of each of the pair of ranging radios with respect to the plurality of fixed-position ranging radios, and determines the position of the first end of the wand with respect to the plurality of fixed position ranging radios. A robotic total station may be used in lieu of the fixed-position ranging radios to monitor the positions of retroreflective elements on the wand.
