Engineering Contradiction Analysis
1Manufacturing precision
If traditional methods are used to generate virtual reality environments, then the environments can be simulated with high fidelity, but the process is time-consuming and costly requiring specialized training
Solution Approach 1:
The system enables ordinary users to autonomously capture 3D room models using their smartphones without requiring specialized training or equipment. The automated photogrammetry processing handles the complex computational tasks, allowing users to simply point the camera and walk through the space to generate accurate virtual models
Solution Approach 2:
The patent replaces traditional manual surveying and measurement methods with automated image-based photogrammetry. Instead of requiring physical measurement tools and skilled operators, the system uses smartphone cameras and computational algorithms to automatically extract geometric and textural information from multiple images
2Manufacturing precision
If traditional methods are used to generate virtual reality environments, then high fidelity can be achieved, but specialized training and skills are required
Solution Approach 1:
The system eliminates the need for specialized training by providing an automated, user-friendly interface where users simply need to point their smartphone at the environment and walk through it. The complex photogrammetry processing is handled automatically in the background, making 3D model generation accessible to anyone with a smartphone
Solution Approach 2:
The patent introduces automated photogrammetry software as an intermediary between the simple smartphone camera and the complex task of generating accurate 3D models. This intermediary layer handles the computational complexity, translating simple user actions into accurate virtual environment generation
3Measurement precision
If manual measurement and modeling methods are used, then accurate measurements can be obtained, but the process is time-consuming
Solution Approach 1:
The patent replaces manual measurement techniques with automated image-based photogrammetry. The system captures multiple images as users walk through the space, then automatically processes these images to extract precise geometric measurements and generate accurate 3D models without manual intervention
Solution Approach 2:
The system continuously captures images throughout the user's walkthrough of the space, automatically processing each image and accumulating measurement data in real-time. This continuous automated processing eliminates the need for stop-start manual measurements and significantly accelerates the overall modeling process
4Productivity
If photogrammetry with ring paths is used, then image capture efficiency is improved, but the system complexity increases
Solution Approach 1:
The system pre-calculates and presents the user with a guided ring path trajectory before image capture begins. This preliminary action guides the user through the optimal capture sequence, ensuring efficient and complete coverage of the 3D space without requiring complex real-time computational guidance during the actual capture process

AI summary
Systems and methods related to an image capture process using ring paths may include traversing a user device around a ring path in a center of a room, capturing imaging data using the user device during the traversal, and processing the imaging data using photogrammetry. The imaging data may be captured using an imaging sensor associated with the user device, and the imaging data may be processed based on data received from position and orientation sensors associated with the user device. In addition, a three-dimensional model of the room may be generated based on the imaging data.
