Abstract: | The radiance coming from the interior of an uncooled infrared camera has significant effect on the quality of an infrared
image. The classical two-point-correction (TPC) method fails to remove this effect where no TPC data is collected. To overcome
this deficit, this paper presents a three-phase scheme. First, from a set of samples and through least squares fitting, how
the TPC datum varies with the interior temperature of the camera is determined. On this basis, all the necessary TPC data
are calculated. Finally, the collected infrared image is corrected with the TPC method. Theoretical analysis and experimental
results show that, for a proper interior temperature of the camera, the scheme can remove the effect effectively. |
