The key of high temperature measurement by using CCD image sensor is to recognize the measured object accurately. From analyzing the characteristic of the noises in high temperature radiator color image

an image recognition method of high temperature radiator is proposed

which is based on the color information of a high temperature radiator. By segmenting the red and green color images

the various noises in high temperature radiator color image are reduced or even eliminated. And then

by synthesizing the results of the segmented red and green color images

the high temperature radiator is recognized accurately. Finally

in order to smooth the image’s edge

the morphology method in mathematics is applied to process the segmented image and remove the dissociations and narrow holes. The experimental results show that the method can recognize high temperature radiator with high accuracy and practicability.
