摘要

This article proposes a three-dimensional visual planning method of green landscape pattern in urban roads based on Rank transformation.Firstly,results of Rank transform of gray image are defined as matching primitives,and the coordinate of landscape pattern is calculated according to the principle of binocular imaging,then three -dimensional point cloud chart is generated,error of position between three dimensional coordinate points of landscape pattern projection is defined,and landscape pattern image point is measured.The green landscape pattern in urban roads through green landscape structure and camera parameters is optimized.Simulation results show that the proposed method has high precision of three-dimensional visual planning of landscape pattern and effectively improves the management quality of green landscape in urban roads.%对城市道路绿色景观进行三维可视化规划设计,能够有效提升城市道路绿色景观的管理质量.对景观的可视化规划,需要定义景观格局投影三维坐标点,得到被测量景观格局图像点位置的误差,完成绿色景观的三维可视化规划.传统方法提取景观格局轮廓,给出绿色景观格局设计主动线索特征,但忽略了得到被测量景观格局图像点位置的误差,导致规划精度偏低.提出基于Rank变换的城市道路绿色景观格局三维可视化规划方法.上述方法先将灰度图像的Rank变换结果定义为匹配基元,根据双目成像原理计算景观格局坐标,并生成三维点云图,定义景观格局投影三维坐标点和被测量景观格局图像点位置的误差,通过绿色景观结构和摄像机参数对城市道路绿色景观格局进行优化.仿真证明,所提方法景观格局三维可视化规划精度高,有效地提升了城市道路绿色景观的管理质量.
