摘要
热敏液晶是近年来图象测量技术研究工作中采用的一种新型传感元件，本文介绍了它的色／温转换特性及测量视角对该特性的影响，并采用神经网络来解决用传统方法难以实现的该色／温转换特性的定量表示问题，取得了良好的效果。
?The thermosensitive liquid crystal is a new type of sensor used in the research work on image survey technique recently. This paper introduces its colour/temperature change-over characteristics and influence of surveying camera angle on this one. The quantitative expression for the colour/temperature change-over characteristics, which is difficult to be realized by the conventional method, is solved by using neural networks. The result is satisfactory.
