Geo-Map Video Surveillance System for Movable Camera Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern video surveillance systems face challenges in effectively handling and processing video streams from movable cameras, particularly in displaying and analyzing footage across a geographical area, as existing systems lack efficient methods for real-time data synchronization and visualization of camera trails and search results.
Innovation Solution
A video surveillance system that includes a video management system (VMS) with a geo-map interface, capable of receiving and processing video streams and metadata from both stationary and movable cameras, allowing for search criteria-based identification of targets and displaying results as thumbnails on a geo-map, with optional supplementary search criteria for refining results and visual differentiation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video streams from multiple cameras are collected and stored in a traditional VMS, then the system can provide basic video management services, but the system cannot efficiently handle movable cameras and display video streams according to their changing positions in real-time
Solution Approach 1:
The system dynamically updates the geo-map display to reflect the changing positions of movable cameras in real-time. The video stream display location on the geo-map changes according to the camera's current position, enabling the system to adapt to movable cameras without requiring complex manual reconfiguration
Solution Approach 2:
The geo-map interface serves multiple functions: it displays the positions of both stationary and movable cameras, shows video stream thumbnails at camera locations, and provides a unified view for monitoring all cameras regardless of their mobility status
2Loss of information
If video streams are displayed in a traditional grid layout, then all video streams can be viewed, but operators cannot quickly identify the geographical location and context of each video stream
Solution Approach 1:
The system transitions from a traditional 2D grid layout to a geo-map-based spatial layout, adding geographical dimensionality to the video stream display. Video thumbnails are positioned on the geo-map according to their actual geographical locations, allowing operators to intuitively understand the spatial context of each camera without losing any video stream information
3Quantity of substance
If the system displays all video stream thumbnails on the geo-map, then complete coverage is achieved, but the interface becomes cluttered and difficult to navigate
Solution Approach 1:
The system segments the display of video streams by organizing them according to their geographical locations on the geo-map. Instead of displaying all thumbnails in a single congested area, they are distributed across the geo-map based on their actual positions, reducing visual clutter while maintaining complete coverage of all video streams
Data Source
AI summary
The present disclosure generally relates to video surveillance systems and optionally computer-implemented video management methods for video surveillance systems. A video management system may be configured to display search results of a plurality of video streams as respective thumbnails on a geo-map at respective positions of the search results within a surveillance area.
