Time Slice Video Generation Using Multi-Dimensional Coordinate Restoration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In sports broadcasts, conventional time slice videos are imprecise due to the random occurrence of events, making it difficult to predict and capture significant moments, limiting the ability to generate high-quality, interactive videos.
Innovation Solution
A system comprising multiple cameras, a time slice video providing apparatus, and a user device that receives and processes videos to select a region of interest, restore multi-dimensional center coordinates, and generate a time slice video based on user input, allowing for interactive and high-freedom video generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional time slice video production is used with pre-selected event points, then the production process is simplified, but the precision and accuracy of capturing random sports events is deteriorated
Solution Approach 1:
The system enables users to independently select regions of interest and generate time slice videos without requiring professional video producers. The automated coordinate restoration and image extraction processes allow end-users to create precise time slice videos of random sports events by simply selecting areas on the screen, making the system self-sufficient for various event types.
Solution Approach 2:
The patent introduces multi-dimensional center coordinates (including depth information) to restore 3D spatial relationships from 2D video frames. This dimensional enhancement allows precise localization of events in space, enabling accurate time slice video generation for randomly occurring sports events without pre-defined capture points.
2Device complexity
If fixed camera positions and pre-selected event points are used, then the system complexity is reduced, but the adaptability to various sports events and scenarios is deteriorated
Solution Approach 1:
The system is designed to handle multiple types of sports events and scenarios through a universal coordinate restoration mechanism. By using positional relationship information between cameras and multi-dimensional coordinate calculations, the same system can adapt to different sports, venues, and event types without requiring complex reconfiguration or specialized setups for each scenario.
3Device complexity
If manual selection of event occurring points by producers is used, then the video generation process is simplified, but the response time and immediacy of capturing random events is deteriorated
Solution Approach 1:
The automated system allows immediate user-driven video generation without requiring manual producer intervention for coordinate calculation or image extraction. Users can directly select regions of interest and the system automatically processes coordinate restoration and generates time slice videos in real-time, eliminating delays associated with manual production workflows.

AI summary
A time slice video providing apparatus includes a video receiving unit configured to receive multiple videos recorded by multiple cameras, a selection unit configured to select a region of interest from at least one of the multiple videos, a coordinate restoring unit configured to restore multi-dimensional center coordinates based on the selected region of interest and positional relationship information between the multiple cameras, and a generation unit configured to extract each image from the multiple videos based on the restored multi-dimensional center coordinates and generate a time slice video using each of the extracted images.
