摘要
本文通过温漂分析和系统建模，提出一种图象传感信号的综合温度补偿方法。该方法避开了难于检测的温漂参量，借助易测的相关参量的在线估值，适时给出误差补偿量．该方法用于大温差测试现场，结果令人满意。
In this paper, a compensation method of the temperature drift of the image sensor caused by ambient temperature change was presented through the analysis of temperature drift and the system modling. The difficulty in the direct measurement of temperature drift was avoided by means of the on-line estimated value of the relative parameters and the given value of error which should be compensated on time. The application to the testing ground of large temperature difference showed that this method is satisfactory.
