Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current movement trajectory playback methods fail to accurately reconstruct navigation scenarios encountered by users during real-world actions, presenting a simple map interface that lacks realism and immersion.
Innovation Solution
A method and apparatus that utilize a three-dimensional virtual scene to map a real movement trajectory, setting a virtual object and lens with a preset relative positional relationship, controlling the virtual object to move along the trajectory while capturing images, and displaying the images in a three-dimensional format.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a simple map interface is used for movement trajectory playback, then the device complexity is reduced and ease of operation is improved, but the realism and immersion of the playback is compromised
Solution Approach 1:
The patent creates a virtual copy of the real-world navigation scenario by mapping the real movement trajectory onto a three-dimensional virtual scene. This virtual scene replicates the environmental features, landmarks, and spatial relationships of the actual location, allowing users to experience the playback without needing the physical navigation system. The virtual object and lens system copies the essential characteristics of real-world navigation while presenting them in an immersive digital format.
2Reliability
If a three-dimensional virtual scene with virtual object and lens is used to reconstruct navigation scenarios, then the realism and immersion are improved, but the device complexity and computational requirements increase
Solution Approach 1:
The patent divides the complex task of trajectory playback into separate functional modules: (1) obtaining the real movement trajectory data, (2) mapping it to the three-dimensional virtual scene, (3) controlling the virtual object to follow the trajectory, and (4) capturing images through the virtual lens system. This segmentation allows each component to be optimized independently and facilitates better computational resource management while maintaining high realism in the reconstructed navigation scenarios.
Solution Approach 2:
The patent introduces a virtual lens as an intermediary element between the virtual object and the user's visual perception. This virtual lens system acts as a mediator that processes the three-dimensional virtual scene and presents it in a format that mimics real-world visual experience. The lens parameters and positioning serve as intermediaries that bridge the gap between digital virtuality and perceived reality, enhancing immersion without requiring direct complex interactions.
3Stability of the object's composition
If the virtual lens maintains a preset relative positional relationship with the virtual object, then the consistency and stability of the playback are improved, but the flexibility and adaptability of the system are reduced
Solution Approach 1:
The patent implements dynamic adjustment capabilities that allow the virtual lens parameters and positioning to be modified during playback based on user needs or scenario requirements. While the system maintains preset relative positional relationships to ensure consistency and stability during normal operation, it incorporates dynamic adjustment mechanisms that enable adaptability when needed. This dynamic characteristic allows the system to balance between maintaining stable, consistent playback and providing flexible adaptation to different user scenarios.
