Abstract: A pattern attaching technique involves (1) obtaining a first collection of data libraries associated with a first set of intersection points among a first set of lines in a first two-dimensional (2D) drawing and a second collection of data libraries associated with a second set of intersection points among a second set of lines in a second 2D drawing and (2) comparing the first collection of data libraries and the second collection of data libraries in order to determine whether the first 2D drawing and the second 2D drawing represent a same portion of a real-world environment. Each data library associated with a given set of intersection points includes location information that describes a respective location of each respective intersection point in the given set of intersection points relative to each other intersection point in the given set of intersection points.

Abstract: The present disclosure is directed to a software tool that facilitates the presentation of a three-dimensional view of a construction project as well as the generation of various types of two-dimensional technical drawings based on this three-dimensional view. In one implementation, the software tool causes a computing device to engage in the following operations. The computing device may receive an indication of a desired clip height of a three-dimensional view at which to generate a two-dimensional technical drawing; identify a subset of meshes that intersect with a two-dimensional plane at the desired clip height; determine respective portions of each mesh that intersect the two-dimensional plane at the desired clip height; compile a dataset that defines the two-dimensional drawing; and render the two-dimensional drawing using the compiled dataset.

Abstract: The present disclosure is directed to a software tool that engages in a pattern matching technique. In one implementation, the software tool retrieves a two-dimensional drawing and identifies walls as lines, rotates the drawing until a threshold number of lines are aligned with either the X or Y axes, discards lines that are not aligned with either the X or Y axis, identifies intersection points, identifies a subset of intersection points that have a maxima or minima coordinate, constructs a data library indicative of the relative positions of the points in the identified subset; and compares the constructed data libraries for the two-dimensional drawing to data libraries constructed for another two-dimensional drawing.

Abstract: Disclosed herein is an improved AR technology for aligning virtual content with a real-world environment. In one aspect, the disclosed process may involve a first computing device receiving an indication that a second computing device detected a given QR pattern on a given strip of QR tape installed in a real-world environment. In response to receiving the indication, the first computing device may obtain installation information regarding a layout of the given strip of QR tape. Based at least on an identifier of the given QR pattern and the information regarding the layout of the given strip of QR tape, the first computing device may then determine a position and orientation of the second computing device, align virtual content on the real-world environment, and instruct the second computing device to present a view of the real-world environment that has the aligned virtual content superimposed onto the real-world environment.
