Panoramic Scene Switching via 3D Model Transparency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing panoramic display technologies result in unnatural scene switching and suboptimal display effects due to the reuse of a three-dimensional ball model and re-mapping of panoramic images, leading to a need for improved methods to transition between scenes.
Innovation Solution
A method and apparatus for switching panoramic scenes by obtaining and generating panoramic models for the current and target scenes, controlling the transition based on scene switching direction and preset distance, and adjusting transparency to achieve a smooth shuttle effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If panoramic image material is replaced and re-mapping is performed for scene switching, then scene switching functionality is achieved, but the switching appears unnatural and display effect deteriorates
Solution Approach 1:
A three-dimensional model serves as an intermediary carrier between panoramic images. Instead of directly replacing panoramic images which causes unnatural switching, the system maps panoramic images onto a three-dimensional model and transitions between models. This intermediary structure enables smooth, natural scene switching while maintaining high display quality.
Solution Approach 2:
The system changes parameters by switching between different three-dimensional models with varying transparency parameters. During scene transitions, the transparency of the current model is gradually reduced while the target model's transparency is increased, creating a natural fading effect that improves display quality and eliminates abrupt switching.
2Ease of manufacture
If a three-dimensional ball model is reused for panoramic display, then display functionality is achieved, but scene switching becomes unnatural
Solution Approach 1:
The system segments the panoramic display into multiple three-dimensional models, each representing a different scene. Instead of using a single reused ball model, multiple specialized models are created, allowing each scene to have its own optimized three-dimensional representation. This segmentation enables natural transitions while maintaining implementation simplicity.
Solution Approach 2:
The system creates copies of three-dimensional models for different scenes rather than reusing a single model. Each scene has its own copied three-dimensional model that can be independently optimized and transitioned to, providing natural scene switching while keeping the overall system implementation straightforward.

AI summary
A method for switching a panoramic scene includes: obtaining a first panoramic model of a current scene; obtaining panoramic model information of a target scene, and generating a second panoramic model of the target scene based on the panoramic model information; and obtaining a scene switching direction and a preset distance, and controlling a switch from the first panoramic model to the second panoramic model based on the scene switching direction and the preset distance, for displaying the target scene.
