Motion Detection Region Definition via Selection Grid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Configuring security video cameras for motion detection can be complicated and inconvenient, particularly when users want to monitor specific areas within the camera's field of view, such as in front of a door or along a path, as existing systems lack intuitive methods for defining precise detection regions.
Innovation Solution
A selection grid is displayed over the camera's field of view, allowing users to select and customize grid elements to define motion detection regions, which can be sent to a motion detection system to generate a mask for video feed processing, enabling notifications for detected motion, with options for grid size, position, and shape adjustment, and automatic selection based on criteria.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional motion detection configuration methods are used, then the system can detect motion in the entire field of view, but the configuration process is complicated and inconvenient for users who want to monitor specific areas
Solution Approach 1:
The field of view is divided into a grid of selectable regions, allowing users to configure motion detection by selecting individual grid cells rather than configuring the entire field of view. This segmentation transforms a complex configuration task into simple cell selection, directly resolving the contradiction between ease of operation and device complexity.
Solution Approach 2:
A visual overlay interface is introduced as an intermediary between the user and the motion detection configuration system. This interface displays the field of view with grid cells and allows users to select detection regions through intuitive visual interaction, eliminating the need for complex parameter configuration and resolving the ease of operation versus configuration complexity contradiction.
2Measurement precision
If users want to define precise detection regions for specific areas, then monitoring effectiveness improves, but the configuration process becomes more complicated
Solution Approach 1:
The field of view is divided into a grid of selectable regions, allowing users to configure motion detection by selecting individual grid cells rather than configuring the entire field of view. This segmentation transforms a complex configuration task into simple cell selection, directly resolving the contradiction between ease of operation and device complexity.
Solution Approach 2:
Different grid cells can be independently selected or deselected to create customized detection regions tailored to specific monitoring needs. This local quality approach allows precise control over which areas are monitored while keeping the overall configuration process simple through the grid interface.
3Reliability
If the entire field of view is monitored, then comprehensive coverage is achieved, but false notifications increase and detection effectiveness for specific areas decreases
Solution Approach 1:
The system extracts only the relevant portions of the field of view for motion detection by allowing users to select specific grid cells. This extraction eliminates unnecessary monitoring of areas that do not require attention, reducing false notifications while maintaining configuration simplicity through the grid selection interface.
Solution Approach 2:
Instead of monitoring the entire field of view (excessive action), the system allows users to select only the necessary portions for monitoring (partial action). This approach improves notification accuracy by focusing detection resources on relevant areas while keeping the configuration process simple through intuitive grid selection.

AI summary
A method, performed by a computer device, may include receiving a request to set up motion detection for a camera. The method may include generating a selection grid for a field of view associated with the camera, wherein the selection grid includes a plurality of grid elements; selecting one or more grid elements of the plurality of grid elements; and configuring motion detection for a video feed from the camera based on the selected one or more grid elements.
