Abstract:
Initial trajectory data that provides an initial description of an approximate trajectory of a device during a time period, and correction data that indicates a location of the device outside the approximate trajectory of the device within the time period, are received. A modified trajectory data that provides a modified description of a corrected trajectory of the device is generated. In particular, terms to express (i) location constraints that limit deformation of the approximate trajectory of the device and (ii) a modification constraint that limits departure of the corrected trajectory of the device from the location indicated by the correction data are generated, and the initial description of the approximate trajectory of the device is modified using the generated terms.
Abstract:
A method and system for applying photo texture to geolocated 3D models operates within a 3D modeling system. The modeling system includes a modeling application operating on a workstation and a database of geotagged imagery. A 3D model created or edited within the 3D modeling system is geolocated such that every point in the 3D modeling space corresponds to a real world location. For a selected surface, the method and system search the database of imagery to identify in the database one or more images depicting the selected surface of the 3D model. The method and system identify the boundaries of the selected surface within the image by transforming two or more sets of coordinates from the 3D modeling space to a coordinate space corresponding to the image. The portion of the image corresponding to the selected surface is copied and mapped to the selected surface of the 3D model.

Abstract:
A method and system provides increased visual fidelity in a multi-pose three-dimensional rendering of an object by overlaying edge lines. A server sends a multiplicity of two-dimensional renderings of the object to a client device over a network. Each of the 2D renderings depicts the object in a different pose. As the 2D renderings are displayed sequentially, the object appears to move, for example, by pivoting on an axis. The server also sends a multiplicity of overlay renderings to the client device. Each of the overlay renderings corresponds to a respective one of the 2D renderings and depicts edge lines that would appear on the 2D rendering. The edge lines are rendered on a transparent background such that, when a user interface combines one of the 2D renderings with the corresponding overlay rendering, the edge lines are highlighted on the 2D rendering and provide additional visual cues to the viewer.
