中文摘要	计算机画面是数字化核电站人机界面的基本组成元素,画面的复杂程度会影响操纵员对核电站情况的掌握。为对单幅画面进行快速有效的复杂度定量评价,本文提出了一种基于图像熵的定量评价方法。首先对画面做图像化处理,并转化为灰度图,然后利用图像熵的定义,计算整个画面的熵值,并将其作为画面复杂度的度量。实验结果表明,图像熵作为画面复杂度的定量评价指标,与人工评价结果具有一致性,能反映人对画面复杂度的综合感受。此方法可应用于实际工程设计,特别是在设计初期不具备实验评价和专家评价的条件时,用来对画面进行复杂度测量,可避免画面过度复杂、改善人机交互。; Computerized displays are the basic elements of the human-machine interface in the digital nuclear power plant,of which the complexity will impact the situation awareness of operators.In order to make a fast and effective quantitative assessment of complexity of a display,a method based on the image entropy was presented.The human-machine interface was converted into a gray scale image,and then the entropy of the display was calculated using the image entropy formula as a measurement of the complexity.The experiment result shows that the complexity measurement of the display based on the image entropy is according with the assessment result by human being,and can reflect the cognitive feeling of the operator.This method can be used in practice,especially at the early stage of the design,where the validation by experiment or by expert is not ready.It can be used to measure the complexity of a display to avoida too complex design and to improve the human-machine interaction.
