Gas Detection Mask Generation via Accumulated Image Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas detection devices face challenges in reducing false alarms, making it difficult to set an appropriate mask range for suppressing notifications, leading to inefficient use of resources and time.
Innovation Solution
A gas detection device and method that generates accumulated data from multiple images over a predetermined period to create a mask image, suppressing notifications based on the frequency of gas detection, thereby automating the mask generation process and reducing manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mask is used to suppress notification of detected gas, then false alarms are reduced, but it is difficult to determine the appropriate mask range leading to increased complexity in mask creation
Solution Approach 1:
The gas detection device automatically generates the mask image by accumulating detection results and identifying frequent detection regions, eliminating the need for manual mask creation and reducing operational complexity while maintaining false alarm suppression
Solution Approach 2:
The device performs preliminary accumulation of detection data over time to pre-identify regions that frequently trigger detections, creating a mask image in advance that suppresses false alarms before they become problematic
2Reliability
If manual mask creation is performed, then false alarms can be suppressed, but the number of steps and time required for mask creation increases
Solution Approach 1:
The system automatically generates mask images by accumulating detection results and identifying frequent detection regions, eliminating manual intervention and significantly reducing the time required for mask creation while maintaining effective false alarm suppression
Solution Approach 2:
The device uses accumulated detection data as feedback to automatically adjust and generate mask images, creating a closed-loop system that continuously improves mask accuracy without requiring manual time investment
3Reliability
If the mask range is set too broadly, then false alarms are reduced, but legitimate gas detections may be suppressed
Solution Approach 1:
The mask image is generated with spatially varying properties, applying suppression only in specific regions where detections frequently occur, rather than uniformly across the entire detection area, thus preserving detection accuracy in non-masked regions
Solution Approach 2:
The system dynamically adjusts the mask parameters based on accumulated detection frequency data, modifying the mask range and intensity to optimize the balance between false alarm suppression and legitimate detection preservation
