Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D model generation technologies do not enable real-time or near real-time generation of 3D models from captured image sequences, leading to potential inaccuracies or incompleteness, with users often unaware of insufficiencies until after processing is complete.
Innovation Solution
A system and method that allows for real-time or near real-time generation of 3D point clouds and models by capturing image sequences, with features to detect anomalies, notify users, and provide options for correction, such as capturing additional images or using algorithms to fill gaps, while also monitoring and adjusting the speed of image capture to ensure data sufficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If image sequences are captured and processed concurrently to generate 3D models in real-time or near real-time, then the generation speed and user feedback capability are improved, but the computational complexity and processing requirements increase
Solution Approach 1:
The patent segments the 3D model generation process into distinct functional modules: image capture module, real-time processing module, anomaly detection module, and model generation module. This segmentation allows concurrent processing of multiple tasks while managing computational complexity through modular architecture, directly resolving the contradiction between generation speed and system complexity.
Solution Approach 2:
The system performs preliminary actions by detecting anomalies and determining data sufficiency during the image capture phase itself, before complete processing is finished. This early detection and feedback mechanism enables real-time intervention and correction, improving generation speed while maintaining manageable processing requirements through proactive rather than reactive processing.
2Loss of time
If the image capture device moves quickly to capture more frames, then the capture time is reduced, but the accuracy and completeness of the 3D model deteriorate
Solution Approach 1:
The patent implements continuous feedback mechanisms where the processing system monitors image quality metrics and anomaly detection results in real-time, then provides feedback to control the movement speed of the image capture device. This closed-loop feedback system dynamically adjusts capture speed to maintain optimal accuracy while minimizing capture time, resolving the contradiction between speed and precision.
Solution Approach 2:
The system dynamically adapts the capture process by adjusting movement speed based on real-time analysis of captured frames and anomaly detection results. This dynamic control allows the system to optimize the trade-off between capture time and model accuracy for each specific scanning scenario, rather than using a fixed speed approach.
3Manufacturing precision
If complete image sequences are captured before processing to ensure model accuracy, then the model quality is improved, but the processing time and user feedback delay increase
Solution Approach 1:
The system performs preliminary processing and anomaly detection on captured image sequences before complete processing is finished. By identifying potential quality issues early in the pipeline and providing user feedback during rather than after capture, the system enables corrective actions while maintaining high model completeness standards, thus resolving the time-quality trade-off.
Solution Approach 2:
The patent maintains continuous useful action by processing images concurrently with capture rather than waiting for complete sequences. This continuous processing approach ensures model completeness through real-time anomaly detection and feedback while minimizing processing delays, allowing the system to maintain high quality standards without sacrificing time efficiency.
4Manufacturing precision
If anomaly detection and correction options are provided in real-time, then the model accuracy is improved, but the system complexity and user interaction requirements increase
Solution Approach 1:
The patent implements feedback mechanisms that detect anomalies during processing and present correction options to users in real-time. This feedback loop enables accuracy improvement through user-informed corrections while managing system complexity through automated detection and structured presentation of correction options, rather than requiring complex manual intervention systems.
