Video Information Control Apparatus Using GPS Correspondence Table
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for displaying video information on a 3D map cannot simultaneously show multiple pictures taken from different positions, limiting the ability to extract and display specific video information captured at specific times and positions from a large volume of unspecified video data.
Innovation Solution
A video information control apparatus and method that uses an input portion, information processor, memory, and output portion to create a correspondence table associating photographing time and position with video data addresses, allowing for the extraction and output of specific video information based on designated time and position inputs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a 3D map is used to display video information with GPS coordinates, then video information can be displayed on a map background, but the map moves depending on the viewpoint of one piece of video and cannot simultaneously display multiple pictures from different positions
Solution Approach 1:
The patent divides the display system into multiple independent map display areas, each capable of showing video information from different positions simultaneously. Instead of having a single moving map viewpoint, the system segments the map into multiple static or independently controllable display regions, allowing each to present a different geographical location and corresponding video feed without interfering with others.
Solution Approach 2:
The patent transitions from a single-viewpoint 3D map to a multi-viewpoint or planar map representation that can accommodate multiple video feeds simultaneously. By adding dimensional capacity to the display system (either through multiple map instances or a comprehensive overview map), the system can present multiple positions and angles at once, resolving the limitation of single-viewpoint display.
2Quantity of substance
If video information from unspecified positions and times is processed, then a large volume of video data can be handled, but it becomes difficult to extract specific video information captured at specific times and positions
Solution Approach 1:
The patent implements preliminary indexing and metadata tagging of video information during the data ingestion phase. GPS coordinates, timestamps, and other identifying information are extracted and stored in an organized database structure before the actual video playback or search occurs. This preliminary organization enables rapid and accurate retrieval of specific video clips based on time and position parameters without having to process the entire video dataset each time.
Solution Approach 2:
The patent introduces an intermediary indexing system or metadata layer that sits between the raw video data and the user interface. This intermediary structure stores extracted features such as GPS coordinates, time stamps, and location names, allowing the system to efficiently search and retrieve specific video information without directly processing the full video content. The intermediary acts as a bridge that enables precise queries against large video datasets.
Data Source
AI summary
Video information, which is photographed with using a GPS built-in video camera, is inputted into a video information server. A video information correspondence table is produced, which associated photographing time of the video information inputted, data address of the video information photographed, and photographing position, and is memorized. According to a request from a display apparatus, the memorized video information correspondence table is searched, and thereby obtaining the video information having the information of time and position designated.
