Principle of Tempetrature Measurement Based on Colorful CCD Pixel Brightness
The formula between temperature of the objects having real surface and luminance of the pixels in the CCD image is deduced. A high temperature field measurement method based on color CCD is discussed according to the principle of two-color pyrometer. The method is used to measure the temperature of a black-body furnace and a coal furnace through a CCD camera, which is scaled by a black-body furnace beforehand. The calculation data are compared with the measurement results of thermocouple, and it shows that the precision of the method is satisfying. Furthermore, the measurement errors are analyzed.
