PTZ Camera Detection Region Alignment via Dynamic Value Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When setting a detection region in a monitoring camera's captured image, if the current PTZ value differs from the PTZ value of a preset designated by detection rule settings, the detection region is set at an incorrect position, mismatching the user's intended location.
Innovation Solution
An image capture device with a determination unit that compares the set PTZ value from the detection rule settings with the current PTZ value and updates the set value to match, ensuring the detection region is set at the intended position specified by the user, even if the PTZ values differ.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the detection region is set using screen coordinates without PTZ value verification, then the setting process is simple and fast, but the detection region is set at an incorrect position when PTZ values differ
Solution Approach 1:
The system implements feedback by comparing the current PTZ value with the PTZ value stored in detection rule settings, and automatically updating the set value when they differ. This feedback mechanism ensures position accuracy without requiring manual intervention, resolving the contradiction between simple operation and accurate positioning.
Solution Approach 2:
The image capture device performs self-correction by automatically detecting PTZ value discrepancies and updating its own settings. The determination unit identifies mismatches and the processing unit self-adjusts the set value, eliminating the need for external intervention while maintaining positioning accuracy.
2Manufacturing precision
If the PTZ value is automatically updated to match current settings, then the detection region position accuracy is maintained, but additional processing steps are required
Solution Approach 1:
The system performs self-service by automatically detecting and correcting PTZ value mismatches without external intervention. The determination unit and processing unit work together to self-adjust settings, maintaining position accuracy while minimizing the need for complex external control processing.
Solution Approach 2:
The determination unit acts as an intermediary component that mediates between the detection rule settings and current camera settings. It compares PTZ values and triggers updates only when necessary, adding minimal processing complexity while ensuring position accuracy.
3Stability of the object's composition
If the detection rule settings store fixed PTZ values, then the settings are stable and consistent, but they become outdated when camera PTZ values change
Solution Approach 1:
The system implements dynamics by making the detection rule settings adaptable to current camera state. While maintaining stable storage of detection region coordinates, the PTZ values are dynamically updated based on current camera settings, allowing the system to adapt to changes while preserving stable detection region definitions.
Solution Approach 2:
The feedback mechanism continuously monitors PTZ value changes and updates detection rule settings accordingly. This ensures the settings remain both stable (consistent detection region definitions) and adaptable (updated PTZ values matching current camera state), resolving the contradiction between stability and adaptability.
