Perspective Image Conversion for Time-Tracked Viewpoint Recall
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing videoconference systems struggle with users' inability to easily recall and re-view captured images from specific viewpoints after a certain period, lacking clear tracking of image capture times and viewpoints.
Innovation Solution
A communication management device and method that receives captured image data and time-series information, enabling perspective projection conversion to display predetermined area images on communication terminals, allowing users to navigate and view specific areas of spherical panoramic images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If captured image data is distributed concurrently without viewpoint tracking, then real-time distribution efficiency is improved, but user ability to grasp viewing perspective and time information deteriorates
Solution Approach 1:
The system pre-associates viewpoint information (camera position, orientation, field of view) and time-series information (timestamp, date) with captured image data at the moment of capture. This preliminary action ensures that when images are distributed concurrently for real-time efficiency, the metadata is already packaged and ready to be transmitted together, eliminating the need for post-processing tracking while preserving complete viewpoint and time information.
2Ease of operation
If viewpoint and time information are stored with captured images, then user ability to revisit specific viewpoints is improved, but system complexity increases
Solution Approach 1:
Instead of storing complex three-dimensional spatial information and temporal data structures, the system creates simplified metadata copies that represent viewpoint (through camera parameters like position, orientation, and field of view) and time (through timestamp and date). These compact metadata copies are attached to each captured image, enabling users to revisit specific viewpoints by selecting from stored metadata without requiring complex storage and retrieval systems.
3Measurement precision
If perspective projection conversion is performed on captured images, then image display accuracy for predetermined areas is improved, but processing time and computational resources increase
Solution Approach 1:
The system performs perspective projection conversion in advance during the image capture phase, using stored viewpoint information (camera position, orientation, field of view) to pre-calculate and generate accurately converted images for predetermined areas. By performing this computationally intensive processing beforehand rather than in real-time during distribution or retrieval, the system achieves high measurement precision for predetermined area images while minimizing processing time delays when users access the images.
Data Source
AI summary
A communication management device includes circuitry that: receives captured image data of a captured image obtained by an image capturing device and time-series information representing a date and time associated with predetermined area information, the predetermined area information representing a predetermined area and is transmitted by a communication terminal that displays a predetermined area image of the predetermined area; and transmits, to the communication terminal, converted predetermined area image data obtained through perspective projection conversion based on the received captured image data and the received time-series information.
