One radiance obtains specific first analysis data to calculate；Analysis data are not limited to temperature value, can also be the temperature difference, pixel
The form of a variety of analysis data such as percentage.
If one of them or it is multiple be unsatisfactory for correspondence, arrive step C04-C05;
For example, the temperature that material 1 measures is 510 DEG C, it is unsatisfactory for the relationship of 0-500 DEG C of corresponding radiance 0.9；Step C04-
C05 is 0.88 to redefine radiance according to radiance table；The calculating of temperature value is then re-started, if according to new true
The temperature that fixed radiance calculates, meets the correspondence of table in Fig. 3, then obtains material 1 is final in the frame thermal imagery first point
Analyse data；If conditions are not met, also needing to continue to determine radiance, the temperature value until calculating and corresponding radiance, meet Fig. 3
In correspondence；At this moment, if the temperature value that material 2 is obtained according to the first radiance, meets the correspondence in table 3, then
Material 2 obtains the first analysis data according to the first radiance；
Obviously, but the multiple material in testing, it is unsatisfactory for temperature value and the correspondence of radiance, then needs all bases again
Table 3 determines respective radiance, and recalculates temperature value.
As described above, when there are many materials in experiment, it can be according to the correspondence of respective temperature and radiance, according to temperature
