Patent number: 11551382Abstract: In example embodiments, techniques are provided for refining tiles of an HLOD tree representing a model in order to display a view. A frontend module selects a tile represented by a node of the HLOD sub-tree and obtains information describing geometry of the selected tile. It determines that the selected tile requires refinement to support the view of the model based on the information describing geometry of the selected tile. A tile refinement strategy is determined from a plurality of tile refinement strategies. The frontend module applies the determined tile refinement strategy to the selected tile to generate one or more child tiles that have a higher resolution than the selected tile, the one or more child tiles represented by child nodes added to the HLOD sub-tree. The frontend module displays the view of the model at least in part by showing tiles represented by nodes of the HLOD sub-tree.Type: GrantFiled: February 18, 2022Date of Patent: January 10, 2023Assignee: Bentley Systems, IncorporatedInventors: Paul Connelly, Raymond B.

Patent number: 11526638Abstract: Techniques are provided for generating score(s) and/or correction(s) for a digital twin representing a utility network. One or more bridges transform data, from a plurality of system and associated with a utility network, to a different format, e.g., relational database format. A process generates a digital twin of the utility network utilizing the data in the different format. A data quality service (DQS) performs evaluations and/or analyses of the digital twin to generate a baseline score and an updated score representing a state of the digital twin if corrections are applied. If the updated score meets or is above a threshold value, the DQS automatically applies and save the corrections to the digital twin. If the updated score does not meet the threshold value, the DQS presents a failure notification and one or more graphical representations of the utility network such that incremental corrections can be made.Type: GrantFiled: October 21, 2019Date of Patent: December 13, 2022Assignee: Bentley Systems, IncorporatedInventors: Alfredo Contreras, Mike Carlisle

Patent number: 11521357Abstract: In one example embodiment, a software application obtains a set of images that include an aerial cable and generates a 3D model from the set of images. The 3D model initially excludes a representation of the aerial cable. The software application processes each image of the set of images to extract pixels that potentially represent cables and determines a position in 3D space of the 3D model of a pair of attachment points for the aerial cable. The software application defines a vertical plane in 3D space of the 3D model based on the pair of cable attachment points. For each of one or more images of the set of images, the software application projects at least some of the pixels that potentially represent cables onto the vertical plane. The software application then calculates a curve representation (e.g., a catenary equation) for the aerial cable based on the pixels projected onto the vertical plane, and adds a cable model defined by the curve representation to the 3D model to represent the aerial cable.Type: GrantFiled: November 3, 2020Date of Patent: December 6, 2022Assignee: Bentley Systems, IncorporatedInventors: Stéphane Côté, William Guimont-Martin

Patent number: 11417046Abstract: In various example embodiments, a variational technique is provided for texturing a polygon mesh based on source images of a scene. The technique combines information from multiple source images to generate a texture map with patches that are the most similar to corresponding patches of the source images. The texture map may be the direct result of an optimization that jointly searches for the texture map and patch correspondence, which is initially unknown. The optimization may use a variational formulation that scores every possible texture map using an energy function that includes a matching term that quantifies how similar patches of the texture map are to the corresponding patches of the source images, and a regularization term that quantifies how complex the patch correspondence is.Type: GrantFiled: December 23, 2019Date of Patent: August 16, 2022Assignee: Bentley Systems, IncorporatedInventor: Jean-Philippe Pons

Patent number: 11373370Abstract: In example embodiments, techniques are provided for enabling use of an AI-generated TIN in generation of a 3D design model by defining site objects (e.g., pads) using multiple (e.g., three) phases (i.e. states). A conceptual phase may be associated with a conceptual data structure, a preliminary phase may be associated with the conceptual data structure and a preliminary data structure, a final phase may be associated with the conceptual data structure, the preliminary data structure, and a final data structure. If changes are made in the conceptual phase, for example, as a result of AI optimization, they may be propagated up to the preliminary data structure and final data structure via the vertical draping. Changes made in the preliminary phase or final phase may be propagated down to the conceptual data structure by treating boundaries and breaklines as spatial constraints.Type: GrantFiled: October 13, 2020Date of Patent: June 28, 2022Assignee: Bentley Systems, IncorporatedInventors: Ron Breukelaar, Barry Mathews, Gabriel Vacarasu, Peter Senft, Scott Devoe

Patent number: 11315322Abstract: In various example embodiments, techniques are provided for representing uncertainty when displaying a rendered view of a multi-dimensional mesh (e.g., created by SfM photogrammetry) in a user interface by applying a real-time, obfuscation filter that modifies the rendered view based on uncertainty in screen space. Where the multi-dimensional mesh is within a limit of data accuracy, the rendered view is shown without modification (i.e. as normal), and a user may trust the information displayed. Where the multi-dimensional mesh is beyond the limit of data accuracy, the obfuscation filter obfuscates detail (e.g., by blurring, pixilating, edge enforcing, etc.) in the rendered view so that a user may visually perceive the uncertainty. The amount of obfuscation may be weighted based on uncertainty to allow the user to visually quantify uncertainty.Type: GrantFiled: August 26, 2020Date of Patent: April 26, 2022Assignee: Bentley Systems, IncorporatedInventor: Fabien Dachicourt
