3D Model Display Control in Free Visual Point Moving Image Streams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies fail to appropriately display 3D models in free visual point moving image content, which allows for flexible eye direction and visual point positioning, leading to an inadequate representation of spatially arranged 3D models.
Innovation Solution
A reproducing device and method that include a reproduction processing unit to reproduce free visual point moving image content and a display control unit to control the display of 3D models based on additional information set in edit data, ensuring appropriate display according to basic information in the edit data stream, along with an edit matter acquisition unit and edit data setting unit for recording and editing purposes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If free visual point moving image content is used to enable flexible eye direction and visual point positioning, then adaptability is improved, but 3D model display appropriateness deteriorates
Solution Approach 1:
The system performs preliminary actions by pre-rendering multiple viewpoint images and pre-positioning 3D models in the virtual space before reproduction. This allows the 3D models to be correctly positioned and displayed according to basic information in edit data, resolving the display appropriateness issue while maintaining the adaptability of free visual point movement.
Solution Approach 2:
The patent introduces an intermediary mechanism through the use of edit data that contains both basic information and additional information. This intermediary structure enables the system to coordinate between the flexible visual point positioning and the precise 3D model display requirements, allowing both adaptability and display appropriateness to coexist.
2Adaptability or versatility
If 3D models are arranged in recreated space with free visual point movement, then adaptability is improved, but device complexity increases
Solution Approach 1:
The system segments the information into two distinct parts: basic information and additional information in the edit data. This segmentation allows the complex task of managing 3D models in free visual point content to be divided into manageable components, reducing the perceived device complexity while maintaining full adaptability.
Solution Approach 2:
The patent uses copying by creating a virtual reproduction of the拍摄 space with positioned 3D models. Instead of requiring complex real-time rendering and positioning systems, the system copies the spatial relationships into pre-prepared viewpoint images and edit data, significantly simplifying the device requirements while maintaining adaptability.
