Point of Interest Tracking in Panoramic Video Playback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face difficulties in navigating and maintaining focus on primary points of interest within panoramic videos, as existing technologies lack effective methods to track and adjust the field of view accordingly.
Innovation Solution
A computer-implemented method and device that track a point of interest (POI) within panoramic videos by recording POI position data and adjusting the field of view based on this data, ensuring the POI remains in view through user inputs or automatic tracking, utilizing a coordinate system and metadata to manage the field of view during playback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the user pans left or right or changes the elevational view up or down in a panoramic video, then the user can see other portions of the surrounding scene, but the user loses track of the primary person or object that was the original subject of the video
Solution Approach 1:
The system continuously monitors the position of the point of interest relative to the current field of view and provides feedback by adjusting the field of view to maintain the POI within the visible area. This closed-loop feedback mechanism ensures that even when users navigate the panoramic video, the primary subject remains trackable.
Solution Approach 2:
The field of view is made dynamic and adjustable based on the tracked position of the point of interest. The system automatically repositions the field of view coordinates to follow the POI, creating a dynamic viewing experience that adapts to the subject's movement within the panoramic scene.
2Reliability
If the field of view is adjusted frequently to follow a moving point of interest, then the point of interest remains in view, but the complexity of the video playback system increases
Solution Approach 1:
The system performs self-service by automatically detecting the point of interest's position and autonomously adjusting the field of view without requiring manual intervention. The playback system manages its own field of view coordinates based on tracked POI data, reducing the need for complex external control mechanisms.
Solution Approach 2:
The system pre-processes the panoramic video to identify and track the point of interest before playback, storing position data in advance. During playback, the system simply retrieves and applies the pre-calculated field of view adjustments, simplifying the real-time processing requirements.
