Dual Radiator Thermal Camera Calibration Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thermal imaging camera calibration methods require significant time to heat or cool calibration radiators to different temperatures, rendering the cameras unavailable for use during this period and thus prolonging the calibration process.
Innovation Solution
A device with two calibration radiators that can be simultaneously brought to different temperatures, along with a movable attachment mechanism and control module, allows for rapid alignment and imaging of both radiators by the thermal imaging camera, enabling simultaneous calibration of multiple cameras without waiting for temperature changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If a single calibration radiator is used and sequentially heated or cooled to different temperatures, then the calibration process can be completed with simple equipment, but the calibration time is significantly prolonged and the camera cannot be used during this period
Solution Approach 1:
The calibration radiator is divided into two independent sections: a first calibration radiator that can be heated to a first temperature, and a second calibration radiator that can be cooled to a second temperature. This segmentation allows both radiators to be prepared simultaneously at different temperatures, eliminating the sequential heating/cooling wait time and enabling the camera to be calibrated without interruption to its operational availability.
Solution Approach 2:
Both the first and second calibration radiators are prepared in advance to their respective target temperatures (first temperature and second temperature) before the calibration process begins. This preliminary preparation ensures that when calibration is needed, both temperature references are already available, eliminating the delay that would otherwise occur while waiting for temperature changes.
2Productivity
If the calibration radiator temperature is changed sequentially (heated then cooled or cooled then heated), then the equipment structure remains simple, but the camera remains unavailable during the temperature transition period
Solution Approach 1:
The calibration system is segmented into two independent calibration radiators with separate temperature control systems. The first calibration radiator is controlled to maintain a first temperature while the second calibration radiator is controlled to maintain a second temperature. This independence allows both radiators to be prepared simultaneously without interfering with each other, maximizing camera availability during calibration.
Solution Approach 2:
The system utilizes independent temperature parameter control for two separate calibration radiators. By changing the temperature parameter of the first radiator to a first temperature and the second radiator to a second temperature simultaneously through independent control systems, the calibration process can proceed without camera downtime, thereby improving productivity.
