Map-Based Video Search Interface for Surveillance Camera Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video search techniques for surveillance cameras are not intuitive, requiring significant time and effort to identify and retrieve recorded videos of an object of interest across multiple channels, especially during incidents like theft or crime, as they rely on event-based searching rather than visual arrangement of camera positions.
Innovation Solution
A video search interfacing apparatus that displays a map of camera positions, allowing users to select cameras in a time series manner along a traffic line of an object of interest, generating a search history and reproducing recorded videos, with features like bookmarking and playback control to enhance user interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If event-based searching is used to search for recorded videos, then the search can be performed systematically, but the search process is not intuitive and requires significant time and effort
Solution Approach 1:
The patent transitions from traditional event-based one-dimensional searching to a map-based spatial visualization that adds dimensional context. Cameras are displayed on a map showing their physical locations, allowing users to visually track the traffic line of objects across multiple camera positions. This spatial arrangement makes the search process more intuitive while maintaining systematic search capabilities.
2Reliability
If the number of surveillance cameras is increased to improve security coverage, then more areas are monitored, but the time and effort required to search through recorded video channels increases
Solution Approach 1:
The map display organizes multiple camera positions spatially, allowing users to visually trace the movement path of objects across camera coverage areas. This reduces the time required to search through recorded videos from multiple channels by providing contextual spatial information at a glance.
Solution Approach 2:
The system pre-organizes camera positions on a map with visual indicators showing which cameras are relevant to the search criteria. This preliminary organization allows users to quickly identify and access relevant video channels without manually searching through all cameras in the system.
3Ease of operation
If camera positions are not visually arranged, then the system structure remains simple, but users cannot intuitively identify cameras associated with incidents
Solution Approach 1:
The patent adds a spatial visualization dimension to the user interface by displaying cameras on a map according to their physical positions. This allows users to intuitively identify cameras associated with incidents by visually tracking the movement path, without significantly increasing system complexity.
