摘要
在三维视景效果评估中有多个指标的评估,一般各指标的权重系数需事先确定,单独运用专家知识或理论模型这两种赋权方法各有利弊,提出了基于专家知识和理论模型的综合赋权方法,通过建立优化模型,直接求解出具有主客观信息的指标权重向量。实验结果表明,确定权向量的方法不同,评估的排序结果也略有差别。采用综合赋权法来确定各指标权重,相应的评估结果即满足视景观察者的需求,又符合严谨的客观评价原则。
There are various indicators for assessing the 3 D visual effects, while the general weight of each index needs pre-determined coefficients individually, for which either the expert knowledge model or theoretical model used has advantages and disadvantages empowerment. Based on expert knowledge and theoretical models, the comprehensive weight method, optimization model, and direct solution of the index weight vectors have subjective and objective information. Experimental results show that the method of determining the weight vector different sort results of the assessment is also slightly different. Integrated weighting method to determine the weight of each index and the corresponding results of the assessment meet the needs of users, and are consistent with the principles of rigorous and objective evaluation.
