Thermographic Camera Control for Temperature Accuracy and Imaging Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Thermographic cameras face challenges in maintaining the reliability of temperature distribution images due to deviations in display temperature over time, particularly during or immediately after temperature correction, which affects the accuracy of imaging.
Innovation Solution
A thermographic camera control method and device that periodically corrects the display temperature at predetermined intervals and acquires temperature distribution images after a standby time shorter than the imaging interval, allowing for improved timing control and user notification during correction processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the display temperature is corrected periodically, then the temperature accuracy is improved, but the reliability of imaging during correction deteriorates
Solution Approach 1:
The system performs temperature correction in advance before imaging, and waits for a standby period to allow the display temperature to stabilize. This ensures that imaging only occurs when the temperature is stable, preventing degradation of imaging reliability while maintaining regular correction cycles for temperature accuracy.
2Productivity
If imaging is performed frequently, then the productivity is improved, but the measurement precision deteriorates due to temperature deviations
Solution Approach 1:
The system implements periodic temperature correction at predetermined intervals, separating the correction cycle from the imaging cycle. By introducing a standby period after correction before imaging, the system maintains high imaging frequency while ensuring each image is captured only when temperature accuracy is guaranteed, thus resolving the conflict between productivity and measurement precision.

AI summary
A thermographic camera control method includes periodically correcting a display temperature of a temperature distribution image at a first interval; and acquiring the temperature distribution image by periodically imaging a temperature measurement target by the thermographic camera at a second interval. The acquiring the temperature distribution image includes imaging the temperature measurement target after elapse of a standby time. The standby time is shorter than the second interval and starts from the correcting the display temperature.
