Surveillance System Event Detection Using Segmented Image Regions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current visual surveillance systems lack the ability to effectively set and monitor specific surveillance events within monitored regions, limiting their functionality in alerting users to critical occurrences.
Innovation Solution
A method and system that allow users to set surveillance events by defining attributes such as text, symbols, and numbers, which are then displayed and analyzed within the surveillance images, triggering alerts or actions when the event occurs, using a display unit and image acquisition devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If surveillance events are set with multiple attributes (text, symbols, numbers) and objects are displayed in surveillance images, then surveillance capability and event detection accuracy are improved, but device complexity and memory storage requirements increase
Solution Approach 1:
The surveillance system segments the surveillance image into multiple regions and displays different surveillance objects (text, symbols, numbers) in different regions. This allows the system to monitor multiple event types simultaneously with high precision while keeping each individual object's processing relatively simple, thus resolving the contradiction between detection accuracy and system complexity.
Solution Approach 2:
The patent superimposes multiple surveillance objects on the two-dimensional surveillance image plane, utilizing spatial dimensionality to organize different event attributes. By displaying text, symbols, and numbers in different spatial positions and layers within the same image, the system achieves comprehensive event detection without proportionally increasing processing complexity.
2Adaptability or versatility
If multiple surveillance objects are displayed in surveillance images to monitor various events, then surveillance coverage and detection capability are improved, but memory storage requirements increase
Solution Approach 1:
The surveillance system uses a unified image processing framework that can handle multiple types of surveillance objects (text, symbols, numbers) simultaneously. This multi-functional approach allows the system to monitor diverse events using a single integrated system rather than separate systems for each object type, thereby increasing surveillance coverage without proportionally increasing memory storage requirements.
Solution Approach 2:
The patent utilizes two-dimensional code technology to encode multiple surveillance objects and event attributes into compact visual representations. By converting complex event information into condensed code formats that can be displayed within the surveillance image, the system achieves comprehensive event monitoring while minimizing the storage space required for event data.
Data Source
AI summary
A method of operating a surveillance system having a display unit configured to display a surveillance image includes acquiring the surveillance image from at least one acquisition device. The method also includes setting surveillance event that includes setting a desired surveillance object indicating an attribute of the surveillance event. Further, the method includes displaying the selected surveillance object with the acquired surveillance image on the display unit to indicate the set surveillance event and analyzing the acquired surveillance image to determine whether the set surveillance event has occurred. In addition, the method includes performing an indicating operation in the surveillance system in response to the occurrence of the set surveillance event.
