Far-Infrared Image Resolution Conversion for Temperature Detail
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing far-infrared radiation imaging technologies struggle to display detailed temperature differences between specific areas of an object while maintaining overall image resolution, especially when there are large temperature variations or when a particular object or range needs to be highlighted.
Innovation Solution
A far-infrared radiation image processing apparatus that receives an image signal, designates a specific area, and converts the resolution for that area independently, allowing for enhanced resolution in the area of interest while maintaining overall image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the gray-scale range is enlarged to represent measurements in image form, then the resolution of output values is improved, but the range of temperatures that can be displayed is narrowed
Solution Approach 1:
The image is divided into a first area containing the object of interest and a second area containing other regions. Different resolution conversion processes are applied to each area: the first area undergoes resolution conversion to enhance temperature detail, while the second area maintains the original resolution to preserve overall temperature range visibility.
Solution Approach 2:
Different processing qualities are applied to different regions of the image. The first area (object of interest) receives enhanced resolution processing to show fine temperature differences, while the second area maintains standard processing to display the full temperature range, creating local optimization of image quality.
2Measurement precision
If the resolution is increased to show detailed temperature differences, then the measurement precision is improved, but the range of gray-scale levels is reduced
Solution Approach 1:
The image processing is segmented into two distinct processing paths: one for the first area that applies resolution conversion to enhance temperature differences, and another for the second area that maintains the original gray-scale range. This segmentation allows both high precision and wide range to coexist in different regions.
Solution Approach 2:
High measurement precision is applied locally to the first area where the object of interest is located, while the second area maintains standard gray-scale levels. This local quality approach ensures that detailed temperature differences are visible where needed without sacrificing the overall temperature range display capability.
3Measurement precision
If resolution conversion is applied to the entire image, then the temperature resolution is enhanced, but the background and nearby objects become highlighted instead of the object of interest
Solution Approach 1:
The image is segmented based on the location of the object of interest, creating a first area that contains the object and a second area that contains other regions. Resolution conversion is selectively applied only to the first area, ensuring that the object of interest receives enhanced temperature resolution while the background maintains its original appearance.
Solution Approach 2:
Enhanced temperature resolution is applied locally to the first area containing the object of interest, while the second area maintains standard resolution. This local quality approach ensures that the object of interest is properly highlighted with detailed temperature information without unnecessarily processing the entire image.
