摘　　要：城市整体规划的图像三维重构中容易受到边缘像素特征点的干扰导致空间的利用率下降,规划精准度不高,为了提高城市整体规划的空间利用效能,提出一种基于激光扫描技术的城市整体规划优化方法。采用激光扫描技术对城市建筑进行网格化分区图像采集,对采集城市整体规划网格图像进行均匀分割,提取图像的边缘轮廓特征,根据激光扫描图像的灰度等级进行城市整体规划过程中的色彩搭配和空间分布配置,采用关联参量估计方法求得城市整体规划中的建筑尺度、位置、主方向等参量信息,根据估计的参量实现城市整体规划优化设计。仿真结果表明,采用该方法进行城市整体规划设计,提高了城市空间的利用率,城市规划的色彩搭配、空间位置、建筑物大小比例等方面配比效果较好,输出规划效果图的质量较高。In the imaging 3 D reconstruction, urban overall planning is easy to be interfered by edge pixel feature points which leads to the low utilization of the space and low precision of the plan. Therefore, this paper put forward an optimization based on laser scanning to improve the space utilization efficiency of urban overall planning. First collect grid filed images of urban buildings based on laser scanning, averagely segment the images and extract their edge contour features. Then allocate colour and space in the planning process according to the gray level of laser scanning images, and calculate the building dimensions, locations, major directions and other parameters by using correlation parameter estimation method. Finally realize urban overall planning optimization design. The simulation results show that this method improves the utilization of urban space, color matching, spatial location, the proportions of building size and other aspects, and the quality of the output planning is higher.
