Dynamic Spatial Size Markings in Virtual 3D House Models
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual reality technologies in real estate, such as VR house viewing systems, fail to provide users with precise spatial dimensions of objects and rooms, limiting their ability to accurately assess furniture placement and space utilization, which hampers the immersive experience.
Innovation Solution
A method and apparatus that automatically generate and display spatial size markings in virtual three-dimensional house models by aligning a three-dimensional house model with a plane layout to calculate real dimensions of rooms and objects, and dynamically determine when to show these markings based on the user's field of view, ensuring intuitive and clear spatial size indication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If spatial size markings are always displayed in VR house viewing, then users can obtain precise dimensional information, but the visual clarity and immersion are reduced due to marking interference
Solution Approach 1:
The patent implements dynamic display of spatial size markings based on user interaction state. When users are in exploration mode, markings are hidden to maintain immersion. When users activate measurement mode (e.g., through gesture recognition or button press), markings are displayed to provide dimensional information. This dynamic switching resolves the contradiction by adapting the display state to user needs.
Solution Approach 2:
The patent extracts spatial size information from the immersive VR scene and presents it in a separate, non-intrusive overlay format. The markings are positioned at the periphery of the visual field or in dedicated UI regions, separating the measurement information from the main viewing experience. This allows users to access dimensional data without having permanent visual markers interfering with their immersion.
2Loss of information
If spatial size markings are displayed for all objects and rooms, then complete dimensional information is provided, but the complexity of the display system increases
Solution Approach 1:
The patent implements selective display of spatial size markings based on local conditions. Rather than uniformly displaying all measurements, the system prioritizes showing dimensions for objects or rooms that are currently in focus, recently interacted with, or have unusual dimensions. This local quality approach provides necessary information while avoiding the complexity of managing and displaying all possible measurements simultaneously.
Solution Approach 2:
The patent implements on-demand display of spatial measurements rather than continuous display of all measurements. Users can trigger measurement display for specific objects or areas as needed, providing partial information when necessary rather than overwhelming the system with complete information always visible. This reduces display complexity while maintaining information availability.
3Object-affected harmful factors
If spatial size markings are displayed in peripheral areas, then visual interference is reduced, but the precision of spatial perception is affected
Solution Approach 1:
The patent presents spatial size information by transitioning from the three-dimensional immersive environment to a two-dimensional overlay representation. Measurements are displayed in UI panels or overlay graphics that reference the 3D space but present data in a structured 2D format. This dimensional transition allows precise numerical information to be conveyed without the visual interference of 3D markers in the immersive space.

AI summary
The present disclosure provides a method and an apparatus for automatically generating and displaying a relevant dimension in a virtual three-dimensional house model. The method includes: acquiring a plane layout and a three-dimensional house model of a single house; aligning a top view or a cross-sectional view of the three-dimensional house model with the plane layout to obtain a correspondence relationship between a unit length of the three-dimensional house model and a unit pixel of the plane layout; calculating a real length corresponding to the unit length of the three-dimensional house model according to the correspondence relationship; and calculating a real dimension of a room and/or an object in the house according to the real length corresponding to the unit length of the three-dimensional house model for the purpose of presentation.
