Video Surveillance Trail Mapping on Geo-Maps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern video surveillance systems face challenges in intuitively handling and displaying video streams from movable cameras, requiring innovative solutions to provide meaningful and user-friendly presentations of live or retrieved video streams.
Innovation Solution
The implementation of a video management system (VMS) with user interface windows that utilize trail markers mapped onto a geo-map, allowing users to actuate markers for corresponding video streams, maintaining map clarity and enabling intuitive access to incidents or objects of interest.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a continuous trail is displayed on the geo-map to show the movable camera's path, then the trail is clearly visible, but the map details become obfuscated and hard to see
Solution Approach 1:
The continuous trail is segmented into discrete trail markers spaced at specific time intervals along the camera path. Instead of displaying an unbroken line, the system places individual markers at key positions, which reduces visual clutter while still effectively showing the camera's movement trajectory and allowing map details to remain visible between markers.
2Loss of information
If multiple trail markers are displayed to represent camera positions at different times, then the temporal progression is clearly shown, but the geo-map becomes cluttered and less readable
Solution Approach 1:
Different visual properties are applied to trail markers based on their temporal characteristics. Markers are spaced at meaningful time intervals rather than uniformly, and may use different visual styles (such as icons or symbols) to indicate different time periods or camera states. This allows temporal information to be conveyed effectively while maintaining map readability in other areas.
3Measurement precision
If the system displays detailed trail information for movable cameras, then the user can track camera movement accurately, but the user interface becomes complex and harder to use
Solution Approach 1:
The system creates a simplified visual representation (copy) of the camera's actual path on the geo-map. Instead of displaying all raw position data points, it generates a condensed trail marker representation that captures the essential movement pattern and temporal progression. Users can interact with these simplified markers to access detailed information when needed, maintaining interface simplicity while preserving measurement precision.
