摘　　要：针对倾斜摄影测量在单体建筑物建模中立面信息获取不足的问题,基于贴近摄影测量,以单体建筑物为对象,研究其在精细化建模中的应用。首先,根据选取对象的实际尺寸及形状特点,设置合适参数规划最优航线;之后,利用无人机贴近立面飞行,获取高分辨率影像,在Context Capture中进行数据处理生成实景三维模型。分别从模型的相对精度和立面纹理的完整性两方面对实验结果进行分析。结果表明:与倾斜摄影测量相比,该方法得到的三维模型相对精度达到毫米级,可满足相关规范对单体化建模的要求;模型立面纹理更加完整、分辨率更高。In view of the problem of insufficient information acquisition on neutral surface of single building modeling by oblique photogrammetry,based on nap-of-the-object photogrammetry,this paper studies the application of single building in fine modeling.Firstly,according to its actual size and shape characteristics,the optimal route is planned with appropriate parameters.Then,fly UAV closing to the elevation to obtain high resolution images,and use Context Capture for data processing to generate 3D real scene model.The experimental results are analyzed in terms of the relative accuracy of the model and the integrity.The results show that:the relative accuracy of the 3D model is millimeter compared with that of the oblique photogrammetry,which can meet the requirements of relevant specifications for monomer modeling;the model facade texture is more complete and the resolution is higher.
