High accuracy temperature measurement method for continuously moving heating element

摘要

Problem to be solved: to establish a precise temperature measuring method of a heating element continuously moving by continuously measuring accuracy in non-contact measurement of the temperature distribution of a heat generating body continuously moving and suppressing the accuracy lowering by the discontinuity of the measurement image caused by the change of velocity in the measurement line.A camera in which a filter of two wavelengths is arranged in mosaic is prepared in each pixel of the CCD or C-MOS sensor.A light shielding material is placed on the upper part of the object to be measured for the flow heating element so as to expose the heating element in a rectangular strip shape having a long side perpendicular to the flow.The image of the strip is obtained from the shape of the non heating material by the continuous camera and the position of the non heated material is obtained by processing the multiple strip images, and it is obtained as a continuous or single image, and it is processed by the two color temperature method, and the temperature distribution is obtained, and the measurement method of high accuracy can be establishedDiagram
