Abstract

A color image processing technique has been applid to measure the temperature on a wall cooled by a cold air jet. Temperature distribution on the wall was visualized by a thereto-sensitive liquid crystal sheet. To achieve the color image analysis, the optical characteristics affecting to the temperature measure-ments, e.g, intensity of refractive light, relative angle between camera, crys-tal sheet and illumination, media configurations between camera and the crystal sheet, were quantitatively evaluated. The reflected colors from the liquid crys-tal-sheet were captured through a 3-tips color TV camera and the temperature distribution was obtained through a neural network color-temperature calibration scheme. This color image analysis is capable of measuring the spatial distribu-tion of mean temperature on the wall.
