【摘要】：計(jì)算機(jī)畫(huà)面是數(shù)字化核電站人機(jī)界面的基本組成元素,畫(huà)面的復(fù)雜程度會(huì)影響操縱員對(duì)核電站情況的掌握。為對(duì)單幅畫(huà)面進(jìn)行快速有效的復(fù)雜度定量評(píng)價(jià),本文提出了一種基于圖像熵的定量評(píng)價(jià)方法。首先對(duì)畫(huà)面做圖像化處理,并轉(zhuǎn)化為灰度圖,然后利用圖像熵的定義,計(jì)算整個(gè)畫(huà)面的熵值,并將其作為畫(huà)面復(fù)雜度的度量。實(shí)驗(yàn)結(jié)果表明,圖像熵作為畫(huà)面復(fù)雜度的定量評(píng)價(jià)指標(biāo),與人工評(píng)價(jià)結(jié)果具有一致性,能反映人對(duì)畫(huà)面復(fù)雜度的綜合感受。此方法可應(yīng)用于實(shí)際工程設(shè)計(jì),特別是在設(shè)計(jì)初期不具備實(shí)驗(yàn)評(píng)價(jià)和專家評(píng)價(jià)的條件時(shí),用來(lái)對(duì)畫(huà)面進(jìn)行復(fù)雜度測(cè)量,可避免畫(huà)面過(guò)度復(fù)雜、改善人機(jī)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.
