Abstract

The invention discloses a high-temperature temperature field distribution testing device and method based on a color camera. The device comprises an optical part, an electrical part and a software part, wherein the optical part comprises an attenuation filter group and an optical lens; the electrical part comprises a color camera, a data line and a computer; the attenuation filter group, the optical lens and the color camera are in threaded connection in sequence; the color camera is electrically connected with the computer; and a high-temperature target to be measured emits light radiation, the light radiation is attenuated and filtered by the attenuation filter group, a photosensitive chip CCD or CMOS on the color camera converts light signals of corresponding wave bands into electric signals according to R, G and B three primary colors, the electric signals are transmitted to the computer, and the temperature field distribution of the high-temperature target to be measured is analyzed by the software part. The test result is slightly influenced by factors such as the state, the surface roughness and the surface chemical characteristics of the to-be-tested target, high-accuracy test of high-temperature temperature field distribution can be realized, and the temperature field characteristics of the to-be-tested target can be accurately reflected in real time.
