Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing surveillance camera systems require separate computer systems for configuring regions of interest, which is inefficient and requires repeated definition across multiple cameras with overlapping fields of view.
Innovation Solution
A method and system that allows designating regions of interest using portable computing devices or projected light patterns, enabling simultaneous definition across multiple surveillance cameras with overlapping fields of view, and utilizing analytics systems embedded in cameras or external systems to analyze image data for metadata generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate computer systems are used to configure regions of interest for each surveillance camera, then the configuration can be done with precise control, but the system complexity and time required increase significantly
Solution Approach 1:
The patent merges the configuration process across multiple cameras by allowing a single region of interest definition to be automatically applied to multiple cameras with overlapping fields of view. Instead of using separate computer systems for each camera, the system combines the configuration into a unified process where one definition serves multiple cameras simultaneously.
Solution Approach 2:
The patent enables a single region of interest definition to serve multiple functions across different cameras. The same region definition can be applied universally to any number of cameras that share overlapping fields of view, eliminating the need for camera-specific configuration and reducing overall system complexity.
2Adaptability or versatility
If regions of interest are defined separately for each surveillance camera, then the configuration can be customized for each camera's specific field of view, but the time and effort required for configuration increase
Solution Approach 1:
The patent performs preliminary analysis to identify which cameras share overlapping fields of view and which regions of interest should be common across them. By pre-determining the groupings of cameras that can share configurations, the system eliminates redundant configuration steps and significantly reduces the time required to set up multiple cameras.
Solution Approach 2:
The patent automatically copies region of interest definitions from one camera to multiple other cameras that share the same field of view. Instead of manually defining regions for each camera, the system creates a master definition and automatically replicates it across relevant cameras, maintaining camera-specific adaptability while dramatically reducing configuration time.
3Manufacturing precision
If multiple cameras with overlapping fields of view are configured independently, then each camera can be optimized for its specific perspective, but the need for precise positioning and repeated definition increases
Solution Approach 1:
The patent enables the system to automatically identify overlapping fields of view and determine which cameras should share region of interest definitions. The system performs self-analysis of camera positions and orientations to determine optimal configuration groupings, eliminating the need for manual precise positioning and reducing the complexity of camera setup while maintaining optimization for each camera's perspective.
Data Source
AI summary
A system and method of designating regions of interest for surveillance cameras is disclosed. The system enables definition of regions of interest simultaneously across multiple cameras. This is useful when the cameras are positioned to monitor the same region of interest within their scenes. Each camera monitors image data for designation of regions of interest, stores the regions of interest, and analyzes the image data from the cameras based on the regions of interest. Preferably, each camera has an integrated analytics system for analyzing the image data based on the regions of interest. A setup process between a user device (e.g. mobile phone) and the cameras enables definition of the regions of interest. In embodiments, the regions of interest are defined in response to the cameras tracking either the user device or an optical device as an operator moves the devices to outline the regions of interest within the scene.
