Gas Detection Device Dual Imager Position Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas detection devices face challenges in accurately estimating gas leak positions due to disparities between infrared and visible light images, which are exacerbated by varying distances between the detection device and the imaging target, making it difficult to superimpose gas images accurately.
Innovation Solution
The device employs dual imagers, one capturing infrared images influenced by gas absorption and the other capturing images in a wavelength range not affected by gas absorption, with a hardware processor adjusting the display positions of these images to ensure they are comparable, thereby recognizing and minimizing the difference between them.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the position of the infrared camera is different from the position of the visible light camera, then the gas detection device can capture images in both infrared and visible regions, but a disparity occurs between the visible image and the gas image, making it difficult to superimpose the gas image at an accurate position
Solution Approach 1:
The patent introduces a parameter display mechanism as an intermediary element between the two images. By displaying parameters such as temperature values, concentration levels, or positional offset data alongside or between the infrared and visible light images, the system provides a reference framework that helps users understand and correct the disparity between the two imaging systems. This intermediary information layer enables accurate gas leak position estimation despite the physical separation of the cameras.
2Measurement precision
If a parameter for eliminating the disparity is used, then the superimposition accuracy can be improved, but the amount of disparity varies depending on the distance between the gas detection device and the imaging target, making a certain parameter inapplicable
Solution Approach 1:
The patent implements a dynamic parameter adjustment mechanism that automatically adapts to varying distances between the gas detection device and the imaging target. The system calculates disparity correction parameters based on real-time distance measurements or image analysis, and adjusts the superimposition parameters accordingly. This dynamic approach ensures accurate gas leak position estimation regardless of the imaging distance, eliminating the limitation of fixed parameters.
3Ease of operation
If the gas image is superimposed on the visible image without position adjustment, then the display process is simple, but the gas leak position cannot be accurately estimated by the user
Solution Approach 1:
The patent performs preliminary position adjustment and disparity correction automatically before displaying the superimposed images to the user. The system pre-calculates the optimal superimposition parameters based on camera positions, imaging distances, and optical characteristics, then applies these corrections automatically during the display process. This preliminary action ensures that users receive accurately aligned images without needing to manually adjust positions, maintaining operational simplicity while achieving high measurement precision.

Implementation Method 1
a first imager configured to capture an image of an imaging target in an infrared region that is influenced by light absorption by gas
Implementation Method 2
a hardware processor configured to cause a display screen to display a first image captured by the first imager and a second image captured by the second imager, and to change at least one of a first display position of a specific position included in the first image and a second display position of the specific position included in the second image on the display screen

AI summary
Provided are a gas detection device, an information processing device, and a program which enable a user to accurately estimate a gas leak position. The gas detection device includes a hardware processor that causes a display screen to display a first image captured by a first imaging section and a second image captured by a second imaging section, and changes at least one of a first display position of a specific position included in the first image and a second display position of the specific position included in the second image on the display screen. The hardware processor causes the display screen to display the first display position and the second display position so that the first display position and the second display position can be compared with each other so as to recognize a difference between the first display position and the second display position.
