【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。
[Abstract]:Computer picture is the basic component of the human-machine interface in digital nuclear power station. The complexity of the picture will affect the operator's grasp of the nuclear power station.In order to evaluate the complexity of a single picture quickly and efficiently, a quantitative evaluation method based on image entropy is proposed in this paper.Firstly, the image is processed and transformed into gray image, then the entropy of the whole picture is calculated by using the definition of image entropy, and it is regarded as a measure of picture complexity.The experimental results show that the image entropy, as a quantitative evaluation index of picture complexity, is consistent with the result of artificial evaluation, and can reflect the comprehensive perception of picture complexity.This method can be applied to practical engineering design, especially when the conditions of experimental and expert evaluation are not available at the beginning of the design, and can be used to measure the complexity of the picture, which can avoid the excessive complexity of the picture and improve the human-computer interaction.
