Abstract: A system for extending the functionality of a web-based, three-dimensional modeling in a browser application is stored as instructions on a computer-readable medium. The instructions include an interface module that may receive user commands from the browser application that define a script including functions to modify or create a 3D model. The script instructions may cause a rendering of the 3D model to be displayed in a window controlled by the browser application. A modeling engine as a compiled browser plug-in may extends the functionality of the browser application. Further, the modeling engine may include functions to interpret model data corresponding to a 3D model and render the 3D model in accordance with the script. Further instructions include a script interface layer that may expose the modeling engine functions to the interface module for use by the script functions. The script functions extend the modeling engine functions.

Abstract: Novel tools and techniques for defining a search range for conjugate points in a set of images. In one technique, an intra-overlap area in two images can be used to define a search range in which a conjugate point can be found; in an aspect, this search range might be expressed as a distance range from a station at which one or both of the two images were captured. That distance range can be used to narrow the search range in an image captured from another station, substantially reducing both the computation time to identify a conjugate match and the likelihood of identifying an incorrect match.

Abstract: A system for tracking movable crane components to assist maneuvering the crane within a jobsite includes a computing device having a processor which calculates a 3D geospatial location and orientation of a 3D coordinate system for an upperworks that has an origin chosen along an axis of rotation between the upperworks and a lowerworks. The processor calculates a 3D position of the origin of the upperworks based on local coordinates and transforms the 3D position of the origin of the upperworks from the local coordinates to global 3D coordinates using absolute position sensing data from first and second positioning sensors attached to the crane (for instance on the upperworks and the hook, respectively) and using global 3D coordinates specific to the jobsite where the crane is located. The upperworks 3D coordinate system is useable to determine line segments in the upperworks 3D coordinate system for various movable components.

Abstract: Functional extensions are provided for use with a modeling software. The functional extensions provide functionality not otherwise provided by the modeling software. The functional extensions are received from a client device by a server and stored in a database. Thereafter, the server transmits the functional extensions to a second client device, sometimes in response to receiving a request for the functional extension from the second client device. The server may update a user profile to indicate that a functional extension was received from a user operating the client device and, additionally, may transmit the functional extension to the second client device when the server receives an indication that the user is operating the second client device.

Abstract: This application discloses a GNSS reference apparatus having a vector error generator and a reference data server.

Abstract: A first user having a certain set of privileges with respect to an initial three-dimensional (3D) model associates a watermark with the initial 3D model, so that the watermark is displayed whenever the initial 3D model is viewed or edited. A second user having a smaller set of privileges with respect to the initial 3D model is permitted to view, copy and/or modify the initial 3D model, but is not permitted to remove or alter the content of the watermark. The watermark is continuously displayed as the second user works with the initial 3D model. When the second user applies a change to the initial 3D model, an indication of the modifications applied by the second user is generated and stored with the model data corresponding to the updated 3D model.

Abstract: Novel tools and techniques are described for identifying objects and/or persons. In one aspect, a method might comprise obtaining a digital image of an object(s) with a digital image recording device. The digital image may be transmitted to a remote computer system, and compared to multiple preexisting digital images using an image comparison software application running thereon. A set of preexisting digital images matching the digital image of the object(s) may be identified, and a (best match) keyphrase associated with the preexisting digital images may be determined. The keyphrase may be returned to a user computer for user confirmation or rejection. In some embodiments, a point cloud may be generated for each object in the image, and fitted with available 3D models, so as to confirm the keyphrase. In some embodiments, the confirmed keyphrase may be sent to a user computer for implementation in a cadastral survey application.

Abstract: Efficient towed implement guidance to a desired path is achieved by guiding a towing vehicle toward a path on the opposite side of a desired path, then guiding the vehicle back to the desired path. Efficient forward implement guidance to a desired path is achieved by guiding a pushing vehicle along a tractrix. A vehicle leaves a straight line along a tractrix to keep a rear implement on the line as long as possible.
