Rotating Transflective Volumetric Display for 360-Degree Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing volumetric three-dimensional display systems require multiple display devices to achieve a 360-degree perspective, increasing complexity and cost, as they need to split image information into multiple signals to present detailed objects from every angle effectively.
Innovation Solution
A three-dimensional display system featuring a projection body with transflective properties, an optical reflector with rotation capability, and at least one projector that decomposes a three-dimensional image into two-dimensional images projected onto the reflector's surface, allowing for relative rotation to form a 360-degree perspective image without the need for multiple display devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple display devices are used to achieve 360-degree perspective, then the display completeness is improved, but the device complexity increases
Solution Approach 1:
The patent divides the three-dimensional image into multiple two-dimensional cross-sectional images at different heights. Each cross-sectional image is projected separately onto the rotating reflector, allowing the complete 360-degree three-dimensional effect to be achieved through sequential projection of segmented image data rather than requiring multiple simultaneous display devices.
Solution Approach 2:
The patent adds the time dimension to the projection process by sequentially projecting different cross-sectional images at different time points during the rotation cycle. This temporal sequencing allows a single projector to effectively cover all angular positions that would otherwise require multiple simultaneous projectors, reducing system complexity while maintaining complete 360-degree display capability.
2Adaptability or versatility
If multiple display devices are arranged for omnidirectional display, then the omnidirectional capability is improved, but the installation complexity increases
Solution Approach 1:
The rotating reflector serves multiple functions: it acts as the projection surface for all cross-sectional images, provides the rotational mechanism to achieve 360-degree coverage, and eliminates the need for multiple fixed display devices. This single multi-functional component replaces what would otherwise require multiple separate display devices mounted at different positions, significantly simplifying installation while maintaining omnidirectional capability.
3Manufacturing precision
If image information is split into more signals for detailed display, then the image detail is improved, but the system complexity increases
Solution Approach 1:
The system uses periodic rotation of the reflector to sequentially present different cross-sectional images at different angular positions. This periodic action allows the single projector to cycle through all necessary image segments in sync with the rotation, maintaining high image detail through systematic sequencing without requiring complex simultaneous multi-device coordination.

AI summary
A three-dimensional display system is provided. The three-dimensional display system includes: a projection body having a three-dimensional shape and a transflective property; an optical reflector including at least one reflection surface; a first driving structure for driving the projection body or the optical reflector to rotate, so that the projection body and the optical reflector rotate relative to each other; an image processor for decomposing a three-dimensional image of an object to obtain multiple two-dimensional images at different cross-sections of the three-dimensional image, and sending the two-dimensional images to at least one projector configured to project the two-dimensional images onto one of the at least one reflection surface in sequence at a regular interval, and reflect the two-dimensional images to different positions on the projection body by means of the at least one reflection surface, to form the three-dimensional image.
