Patent number: 11893538Abstract: A system and method for capturing and automated processing aerial images of structures to assess structural damage is disclosed. The system comprises a computing system used to obtain images of selected locations associated with known structures at different points in time before and after a natural disaster. The images are used to automatically create three-dimensional models that are used to detect the specific portions of a structure that may be damaged as well as the spatial extent of that damage. In addition, the imagery can be fed into a damage classifier that automatically classifies the degree of damage and generates accurate estimates of repair costs. The system and method may be deployed to quickly assess damage of structures in a disaster area and provide reports of the damage to homeowners and/or insurers.Type: GrantFiled: June 16, 2022Date of Patent: February 6, 2024Assignee: United Services Automobile Association (USAA)Inventors: Jess W. Gingrich, Yangqiu Hu, David Rogers

Publication number: 20230360203Abstract: Systems, devices, and methods are described for providing patient anatomy models with indications of model accuracy included with the model. Accuracy is determined, for example, by analyzing gradients at tissue boundaries or by analyzing tissue surface curvature in a three-dimensional anatomy model. The determined accuracy is graphically provided to an operator along with the patient model. The overlaid accuracy indications facilitate the operator's understanding of the model, for example by showing areas of the model that may deviate from the modeled patient's actual anatomy.Type: ApplicationFiled: June 26, 2023Publication date: November 9, 2023Applicant: Smith & Nephew, Inc.Inventor: Yangqiu Hu

Publication number: 20230293240Abstract: A process according to certain embodiments includes generating a distal femur model including an intercondylar surface model, receiving information related to user-selected points on the intercondylar surface model, generating a datum line extending between the points, generating an axis line, and determining an AP axis based upon the axis line. Generating the axis line includes performing an axis line procedure including generating a plurality of planes along the datum line, generating a plurality of contours at intersections between the intercondylar surface model and the planes, generating saddle points at local extrema of the contours, and fitting the axis line to the saddle points. The process may further include generating an updated datum line based upon the axis line, and performing a subsequent iteration of the axis line procedure using the updated datum line.Type: ApplicationFiled: May 18, 2023Publication date: September 21, 2023Applicant: Smith & Nephew, Inc.Inventors: Stephen Mirdo, Yangqiu Hu

Patent number: 11704872Abstract: Embodiments of the present disclosure provide a software program that displays both a volume as images and segmentation results as surface models in 3D. Multiple 2D slices are extracted from the 3D volume. The 2D slices may be interactively rotated by the user to best follow an oblique structure. The 2D slices can “cut” the surface models from the segmentation so that only half of the models are displayed. The border curves resulting from the cuts are displayed in the 2D slices. The user may click a point on the surface model to designate a landmark point. The corresponding location of the point is highlighted in the 2D slices. A 2D slice can be reoriented such that the line lies in the slice. The user can then further evaluate or refine the landmark points based on both surface and image information.Type: GrantFiled: October 7, 2021Date of Patent: July 18, 2023Assignee: SMITH & NEPHEW, INC.Inventors: Yangqiu Hu, Gaetano Calabrese

Patent number: 11532109Abstract: A graphical representation of an image of a subterranean formation along with log properties of the formation provided in a single graphical representation. Logged formation property values are coded into graphic representations of images of the formation in order to provide a graphical representation which allows the user to visually perceive the formation images and the logged formation properties simultaneously. A method may include receiving an image of a formation, the image including image values based on the formation, and also receiving a log property of the formation, the log property including log property values based on the formation. The log property values of the formation are correlated to corresponding locations in the image. A transfer function with the image values and the correlated log property values as inputs is determined. Based on the transfer function, a joint graphical representation of the image and the log property is rendered.Type: GrantFiled: January 24, 2020Date of Patent: December 20, 2022Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventors: Yangqiu Hu, Naum Derzhi, Jonas Toelke

Publication number: 20220164968Abstract: A core scan alignment service processes core scans to automatically perform, longitudinal and rotational alignment of core sample images. The alignment service fits ellipses to a core sample represented in an image and fits a line through the center of the ellipses to determine a center axis of the image. The alignment service aligns the determined center axis of the image with center axes of other processed images. The alignment service also rotates the image around the central axis while comparing sub-volumes or portions of the image with an adjacent previously aligned image. The alignment service determines a similarity metric between the neighboring images at several rotational positions. The alignment service then rotates the image to a degree of rotation which yielded the highest similarity metric value. The alignment service can output a three-dimensional model or image of an aligned set of core sample images.Type: ApplicationFiled: April 29, 2019Publication date: May 26, 2022Inventors: Yangqiu Hu, Naum Moiseyevich Derzhi, Jonas Toelke
