Electronic device, method, and computer readable recording medium for synchronizing videos based on movement of body
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for synchronizing videos captured by multiple cameras are cumbersome and increase constraint conditions, making it difficult to accurately reconstruct body posture due to time differences between captured frames.
Innovation Solution
An electronic device synchronizes videos based on the movement of a body part by identifying and aligning movement information from different camera views using a neural network, reducing the need for additional equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If time slate or sensor methods are used to synchronize videos, then video synchronization accuracy is improved, but device complexity and constraint conditions increase
Solution Approach 1:
The system uses the body's own movement information as the synchronization reference, eliminating the need for external time slates or sensors. The processor automatically extracts movement features from video frames and uses them to align multiple camera feeds, allowing the subject to serve as their own synchronization tool.
Solution Approach 2:
The patent introduces movement information of body parts as an intermediary element that mediates between multiple video streams. By extracting and comparing movement trajectories of specific body parts across different camera views, the system achieves synchronization without direct camera-to-camera coordination.
2Measurement precision
If multiple cameras capture body posture simultaneously, then reconstruction accuracy is improved, but time differences between frames increase
Solution Approach 1:
The system establishes a feedback loop where movement information from one camera is used to adjust and align the timing of other cameras. The processor continuously compares movement trajectories and applies time shifts to minimize discrepancies, ensuring that posture reconstruction uses synchronized data from all camera views.
Solution Approach 2:
The patent performs preliminary extraction of movement information from video frames before the actual posture reconstruction process. By pre-processing and aligning the temporal data of body part movements, the system prepares synchronized reference data that enables accurate multi-view posture reconstruction without suffering from frame timing mismatches.
