Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional methods are used to generate virtual reality environments, then the environments can be highly detailed and realistic, but the process is time-consuming and costly
Solution Approach 1:
The patent uses photogrammetry to create 3D models by capturing multiple 2D images from different viewpoints and processing them to generate accurate three-dimensional representations of real-world environments. This copying process allows high-fidelity reproduction of real spaces without requiring manual creation, significantly reducing generation time while maintaining environmental realism
Solution Approach 2:
The patent replaces manual measurement and modeling processes with automated computer vision and photogrammetry algorithms. The system automatically processes captured images to generate 3D models, eliminating the need for manual surveying and modeling operations, thereby reducing both time and cost while maintaining precision
2Manufacturing precision
If specialized training and skills are required for VR environment generation, then the output quality can be high, but the accessibility and ease of use are reduced
Solution Approach 1:
The patent enables users to independently capture their own environments using a mobile device and automatically generates the 3D models through automated photogrammetry processing. The system performs self-service by automatically processing captured images, generating 3D models, and creating navigation paths without requiring user expertise in photogrammetry or 3D modeling, thus maintaining accuracy while dramatically improving accessibility
Solution Approach 2:
The patent introduces an automated processing system as an intermediary between the user and the complex photogrammetry algorithms. The mobile application serves as this intermediary, handling the complex image processing and 3D model generation automatically, so users only need to perform simple image capture operations without needing specialized training
3Measurement precision
If manual measurement and modeling are performed, then detailed and accurate 3D models can be created, but the process is complex and time-consuming
Solution Approach 1:
The patent replaces manual measurement processes with automated photogrammetry and computer vision algorithms. The system automatically calculates dimensions, generates 3D models, and creates navigation paths based on processed images, eliminating complex manual measurement procedures while maintaining or improving dimensional accuracy through computational geometry
4Productivity
If photogrammetry and automated processing are used, then the generation time is reduced, but the complexity of the processing system increases
Solution Approach 1:
The patent uses a mobile device application as an intermediary that handles the complex photogrammetry processing. The complexity is encapsulated within the automated processing pipeline, allowing users to benefit from high productivity without needing to understand or manage the underlying computational complexity. The system automatically processes images and generates 3D models through integrated algorithms

AI summary
Systems and methods related to an image capture process using panorama paths may include traversing a user device among a plurality of image capture locations of a room, sweeping the user device at each of the image capture locations, capturing imaging data using the user device during the traversal and/or during the sweep, 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.
