Embodiment Construction
[0050] The overall flow chart of the colorimetric temperature measurement system in the present invention is as follows image 3 As shown, it specifically includes image preprocessing, image registration, information fusion, and temperature calibration. Realize the schematic diagram as Figure 4 As shown, the specific implementation of each step is as follows:
[0051] 1. Image preprocessing
[0052] Ideally, when the infrared focal plane detector is irradiated by uniform light, the output signal amplitude of each pixel should be exactly the same. In fact, due to the inhomogeneity of the semiconductor material used to make the device, mask errors, defects, processes and other factors, the output amplitude will appear uneven, and at the same time there will be some bright or dark spots on the image, which are blind elements ( Also known as invalid elements). Non-uniformity will vary with the temperature of the detector's operating environment. Due to the existence of these...
