Solution Overview
Problem
Current 3D modeling techniques face challenges in efficiently capturing detailed geometry and texture information of objects, particularly in creating accurate 3D object data models for diverse applications, as existing methods often require manual intervention, are time-consuming, or lack comprehensive scanning capabilities.
Innovation Solution
A device comprising multiple scanners positioned strategically around a rotating platform, including cameras and projectors, captures geometry and texture information by projecting patterns and decoding images to generate a raw mesh, which is then processed to create a merged 3D object data model, enabling rapid and accurate data acquisition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple scanners are positioned around a rotating platform to capture comprehensive geometry and texture information, then the completeness and accuracy of 3D model data is improved, but the device complexity increases
Solution Approach 1:
The scanning system is divided into multiple independent scanners positioned around the platform, with each scanner responsible for capturing specific portions of the object from different angles. This segmentation allows comprehensive coverage while maintaining modular system architecture where each scanner unit can be independently controlled and calibrated.
Solution Approach 2:
The system transitions from single-point observation to multi-dimensional observation by positioning scanners in three-dimensional space around the rotating platform. This spatial arrangement enables capture of geometry and texture information from multiple viewpoints simultaneously, creating a comprehensive 3D representation through integration of data from different spatial dimensions.
2Productivity
If scanners operate simultaneously to capture comprehensive object information, then scanning time is reduced, but light interference between scanners occurs
Solution Approach 1:
A light damper element is introduced as an intermediary component between scanners to control and manage light interference. The damper selectively blocks light from one scanner from reaching other scanners during simultaneous operation, enabling coordinated multi-scanner imaging while preventing optical interference that would degrade measurement accuracy.
Solution Approach 2:
The system implements periodic activation of light dampers synchronized with scanner operation sequences. By controlling the timing and periodic engagement of light dampers, the system enables simultaneous scanning operations while preventing light interference through temporal and spatial coordination of light blocking elements.
3Illumination intensity
If light sources are activated for all scanners simultaneously, then illumination coverage is improved, but heat generation increases causing condensation
Solution Approach 1:
The illumination system is segmented by activating light sources individually for each scanner rather than simultaneously for all scanners. This segmented activation pattern provides sufficient illumination coverage for each scanning operation while significantly reducing cumulative heat generation that would otherwise cause condensation on the platform and within the enclosure.
Solution Approach 2:
Light sources are activated periodically in sequence according to scanner operation timing rather than continuously simultaneously. This periodic activation pattern ensures adequate illumination is available when needed while allowing heat to dissipate between activation cycles, preventing temperature buildup and condensation formation.

AI summary
Systems and devices for acquiring imagery and three-dimensional (3D) models of objects are provided. An example device includes a platform configured to enable an object to be positioned thereon, and a plurality of scanners configured to capture geometry and texture information of the object when the object is positioned on the platform. A first scanner is positioned below the platform so as to capture an image of a portion of an underside of the object, a second scanner is positioned above the platform, and a third scanner is positioned above the platform and offset from a position of the second scanner. The scanners are positioned such that each scanner is outside of a field of view of other scanners. Scanners may include a camera, a light source, and a light-dampening element, and the device may include a control module configured to operate the scanners to individually scan the object.
