Temperature is one of the most important parameters to identify the substance state. Its measurement and control play an important role in the national defense, military, scientific experiments, industrial and agricultural production. With unique features, the non-contact temperature measurement technique based on CCD has become a research focus in the field of high temperature measurement.In this paper, the non-contact temperature measurement theory based on CCD is studied systemically. The connection between the output of color CCD and the temperature of radiator is discussed in detail, and aiming at the problem that the temperature measurement is short of the veracity, main sources of the measure errors of monochromatic and the colorimetric are analyzed, and the tricolor temperature measurement method based on CCD image sensor is proposed.After the tricolor temperature measurement principle and calibration method are studied in detail, the structure of the tricolor temperature measurement system based on color CCD image sensor is built up. All the essential instruments of the system are studied, and the select principle is proposed. The software of data acquisition based on VC++.NET and the software of the image analyze based on MATLAB are developed.Some gas rudder images taken from a certain guided missile institutes are processed with the tricolor temperature measurement formula in an emulation way. The result shows that the surface temperature field of high temperature smelting metal can be effectively measured and the temperature measurement precision is increased by the temperature measurement method mentioned in this paper.At present, temperature measurement equipments based on CCD are not mature, most of which are improved in experimental laboratory, and the infrared thermal imaging system is very expensive. The tricolor temperature measurement system researched in this dissertation is of high accuracy, reliability, low price, easy to handle, fine practical value and a prosperous future.
