Turntable Peripheral for Automated 3D Scanning Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 3D scanning techniques face challenges in efficiently capturing a complete and accurate three-dimensional model of an object from all sides, as they often require manual repositioning and alignment of scans, which can be time-consuming and prone to errors.
Innovation Solution
A turntable peripheral device that automatically rotates and tilts an object during scanning, allowing incremental scans to be captured and aligned progressively to create a single, complete 3D model with texture, facilitated by a computing device that communicates with the scanning device to manage the scanning process and provide visual cues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If manual repositioning and alignment of scans is used, then the scanning process can be performed with simple equipment, but the time consumption and error rate increase
Solution Approach 1:
The turntable peripheral enables the object to be automatically repositioned during scanning without requiring manual intervention. The system self-services by automatically rotating the object through multiple angles and positions, allowing the scanning device to capture complete 3D data efficiently while eliminating manual repositioning time
Solution Approach 2:
The turntable peripheral transforms the static scanning process into a dynamic one by automatically rotating and tilting the object during scanning. This dynamic repositioning allows incremental scans to be captured from multiple angles and progressively aligned to create a complete 3D model, significantly reducing total scanning time
2Measurement precision
If manual repositioning is used, then the device structure remains simple, but the alignment accuracy decreases
Solution Approach 1:
The system uses visual cues projected onto the object to provide feedback during the scanning process. The computing device communicates with the scanning device to guide the automatic repositioning, ensuring that incremental scans are captured at the correct angles and positions for accurate alignment and stitching into a complete 3D model
Solution Approach 2:
The turntable peripheral enables dynamic repositioning with precise control over rotation and tilting angles. This controlled dynamic movement ensures that the object is positioned accurately at each scanning stage, improving alignment accuracy compared to manual repositioning while maintaining manageable device complexity
3Productivity
If automatic rotation and tilting is implemented, then the scanning speed increases, but the device complexity increases
Solution Approach 1:
The turntable peripheral implements automatic rotation and tilting mechanisms that dynamically reposition the object during scanning. This dynamic capability allows the system to capture incremental scans from multiple angles and positions automatically, significantly increasing scanning speed and productivity while completing complete 3D models efficiently
Solution Approach 2:
The turntable peripheral serves multiple functions: it rotates the object horizontally, tilts it at various angles, and positions it for different scanning perspectives. This multi-functionality consolidates what would otherwise require multiple separate devices or manual operations into a single integrated peripheral, increasing scanning speed without proportionally increasing overall system complexity
Data Source
AI summary
Examples relate to a turntable peripheral for three dimensional (3D) scanning. In some examples, 3D scan data of a real-world object is obtained while the object is rotated by the turntable peripheral. Positioning commands are sent to the turntable peripheral to rotate the object. The 3D scan data is collected while the turntable peripheral is in an untilted and/or tilted position.
