Vector Map Interface for Faster Video Event Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional video management systems are inefficient and difficult to navigate, requiring users to search through recorded history to find events, and are slow to locate and switch between cameras, especially when events move to different locations.
Innovation Solution
A graphical management system using vector-based mapping that allows users to interactively zoom, pan, and display videos based on location and zoom level, providing an efficient method to navigate both space and time within a monitored environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional video management systems use lists and bitmap images for display, then the system structure is simple, but the user interface is not interactive and navigation is slow
Solution Approach 1:
The patent replaces traditional bitmap image display with a vector-based mapping system that uses mathematical coordinates and geometric shapes to represent camera positions and environments. This substitution enables interactive operations like zooming and panning through coordinate transformation rather than manipulating static images, directly improving user interface interactivity while maintaining system manageability through mathematical modeling.
Solution Approach 2:
The patent introduces an additional interactive dimension by implementing zoom levels and pan operations on the vector map. Users can navigate through space (panning to different locations) and scale (zooming in/out), transforming a static 2D bitmap display into an interactive multi-scale interface. This dimensional enhancement allows efficient location of events and camera switching without increasing fundamental system complexity.
2Loss of time
If traditional systems require searching through recorded history to find events, then all event data is stored, but the time to locate events is excessive
Solution Approach 1:
The patent introduces a vector map as an intermediary interface between the user and the video data. Instead of directly searching through recorded history lists, users interact with the vector map to visually locate events and associated cameras. This intermediary spatial representation dramatically reduces event location time by providing intuitive visual navigation rather than linear list searching, while maintaining access to all stored event data.
3Ease of operation
If traditional systems display static bitmap images, then the display format is simple, but the system is difficult to understand and navigate
Solution Approach 1:
The patent substitutes static bitmap images with a dynamic vector-based mapping system that uses mathematical coordinates, geometric shapes, and transformation operations. This replacement makes the interface more understandable through intuitive spatial relationships and interactive navigation, while the underlying mathematical model keeps the system manageable rather than arbitrarily complex.

AI summary
Systems and methods for monitoring an environment using a Graphical Management System (GMS) are described. The GMS may present a vector image map of the environment for interaction by a user. The user may zoom and pan on the map to generate views of the map with various ranges of detail of the map. Video data from a plurality of video cameras may also be displayed on the map based on the user input and the level of zoom and the location viewed in the map. Further, the user may select a timeline event and sensor data associated with the event and the map may be initialized at the time and location of the event.
