基于云模型的数字影像产品质量综合评价

随着数字影像产品在各领域内的应用越来越广泛,对它的质量研究也越来越受到人们的重视。利用云模型定性与定量之间的转换关系,提出了基于云模型理论的数字影像产品质量综合评价方法。分别采用虚拟云中的浮动云和综合云方法对产品各层质量元素进行综合运算,获得最终评价结果的云模型参数。最后以云模型数字特征图或云滴分布的形式给出最终质量等级。经过实例证实,该方法的评价结果直观、细腻,更加符合实际情况。

Evaluation Model of Digital Map Quality Based on Cloud Model

With the broad application of digital map,its quality have drawn more and more attention.In the paper,a comprehensive evaluation method of the digital map quality was presented based on cloud model by using the mapping between qualitative and quantitative knowledge of the cloud model.This paper used the theory of virtual cloud which included the floating cloud and compositive cloud to calculate the comprehensive result of each layer's quality elements,then obtained the cloud parameters of the finally evaluation.At last the result was described with the digital characteristic figure and the subordinate level,and a quality grade of the product was educed.Testified by the experiment,the finally evaluation was intuitionistic and exquisite,and more likely to be close to the reality.
