摘　　要：对园林景观布局问题进行研究,能够有效提高城市园林的视觉效果。对园林景观的合理布局,需要计算斑块分维数,评估景观优势度,完成园林景观的合理布局。传统方法先计算布局聚集度指数,定量分析景观变化驱动机制,但忽略了对景观优势度进行评估,导致布局效果不理想。提出基于Markov的双目视觉下城市园林景观合理布局方法。利用Markov构建园林景观类型转移概率矩阵,设计园林景观转换函数,通过Markov特性约束方程获得景观布局模型,对斑块数量进行统计,测量斑块面积,计算斑块分维数,通过香农多样性指数对景观优势度进行评估,实现城市园林景观的合理布局。实验结果表明,上述方法可提高各景观模拟情况与实际情况的吻合程度,使园林景观布局更合理,视觉效果更佳。The study on the layout of garden landscape can effectively improve the visual effects of urban gardens.For the rational layout of landscape,it is necessary to calculate the patch fractal dimension,assess the landscape dominance,and complete the rational layout of the landscape. The traditional method first calculates the aggregation index of the layout,and quantitatively analyzes the driving mechanism of landscape change,but ignores the evaluation of landscape dominance,resulting in an unsatisfactory layout effect. A method of rational layout of urban landscape based on binocular vision based on Markov is proposed. Landscape type transtion-probablity matrix was constructed with Markov,the landscape transfer function was designed,landscape layout model was obtained based on constraint equations of Markov characteristics. Then the number of patches was counted up,the patch area was measured,and the fractal dimension was calculated. landscape dominance was evaluated with Shannon＇s diversity index,to realize the reasonable layout of city landscape. The experimental results show that the above methods can improve the degree of agreement between the landscape simulation and the actual situation,and make the landscape layout more reasonable and better visual effects.
