Abstract: A method of rejecting the presence of an object of extrusion within a point cloud. The method comprising receiving, through a data interface, data describing a set of measurements of observed portions of the one or more objects in the scene. The method further comprising receiving data describing an extruded object that is hypothesized to exist in the scene. The method further comprising finding a set of near measurement points comprising measurement points wherein each measurement point is within a predefined distance of the hypothesized extruded object. The method further comprising classifying points within the set of near measurement points associated with the hypothesized extruded object as on-surface or off-surface. The method further comprising rejecting the hypothesized extruded object whose off-surface measurement points exceed an allowable threshold.

Abstract: A method for indicating and computing displacement of Elements with respect to corresponding Design Locations of the Elements. The method comprising loading, through a data interface, data describing a set of measurements (Measurement Data) of one or more Elements in a Scene. The method further comprising receiving data describing the geometry of one or more Elements (Design Models) that are expected to exist in the Scene. The method further comprising receiving data describing the Design Location(s) of these Elements. The method further comprising enabling a user to place a graphical representation of the Design Model in an Approximate Installed Location indicated by the Measurement Data. The method further comprising measuring and reporting the spatial differences between the Design Location and an Approximate Installed Location as indicated by the user-positioned graphical representation of the Design Model.

Abstract: A system for constructing a virtual 3D model of one or more objects within a scene, where the virtual 3D model contains one or more flat faces on each object constructed. In some embodiments, the system may include at least one processing device configured to: receive, through a data interface, data describing a set of measurements of observed portions of the one or more objects in the scene, where the set of measurements was performed by one or more measurement devices; receive, through a data interface or user input device, one or more shape definitions, where the shape definitions define the possible shapes of a virtual 3D model of an object, and where the virtual 3D model of an object is to be constructed from the measurement data, and where the shapes contain one or more regions with primitive geometries.

Abstract: A head covering device including a hood portion and a detachable cover for covering the head, neck and upper back from the sun. The hood portion is formed of an absorbent inner layer of material and a porous outer layer of material which together function to shade the wearer, conserve body water, and allow for cooling the wearer by evaporation of perspiration. Fasteners are provided for removably attaching the cover to the hood portion. A channel is provided which extends through a crown portion of the hood and receives a cord whose ends are adjustably connectable for securing the hood portion onto the wearer's head. Another channel provided along a lower edge of the hood portion receives a cord whose ends are adjustably connectable for gathering the hood portion about the neck of the wearer.
