摘　　要：为改善日照分析传统作业方法,提升效率,研究将实景三维倾斜模型应用于规划审批日照分析工作。以山东青岛为例,利用无人机航飞获取1.8 cm地面分辨率的影像生产倾斜模型,通过全野外实测检核模型房角坐标、特征点高程和间距,评价模型精度,并选取大寒日和冬至日,分别利用倾斜模型和全野外实测数据建模进行日照分析。结果表明,倾斜模型精度符合规范要求,利用倾斜模型进行日照分析的结果整体上与全野外实测结果相近,倾斜模型应用于规划审批日照分析工作具有一定的可行性。In order to improve the traditional operation method and efficiency of sunlight analysis,the real 3D tilt model is applied to sunlight analysis of planning approval.Taking Qingdao,Shandong Province as an example,a 1.8cm ground resolution image was obtained by UAV flight to produce a tilt model.The house corner coordinates,the elevation and spacing of feature points were checked through field measurements to evaluate the accuracy of the model.In addition,the Major Cold day and Winter Solstice day were selected to conduct sunlight analysis by tilt model and the modeling of all field measured data respectively.The results show that the accuracy of the tilt model is in line with the specification requirements,and the results of sunlight analysis using the tilt model are similar to the field measured results on the whole.The application of tilt model to sunlight analysis of planning approval is feasible.
