摘要
历史建筑建模采用传统测量方法,无法准确描绘具体构件,需大量的人力、物力和时间,在作业过程容易造成历史建筑二次损坏。采用静态定点三维激光扫描和车载扫描系统技术的三维建模的方法,缺乏历史建筑的顶部纹理信息且费用高。而仅采用无人机倾斜摄影测量技术虽可快速、简便、有效地获取古建筑的相对位置、部分立面和顶部结构及建筑纹理信息,但是面对狭窄的街巷立面结构变形大、纹理质量不能满足要求。针对这些不足,项目采用空中航摄与地面摄影的方式,将空中影像与地面影像组合解算,从而形成高精度的历史建筑模型。
Historical building modeling uses traditional measurement methods and cannot accurately describe specific components.It requires a lot of manpower,material resources and time.It is easy to cause secondary damage to historical buildings during the operation process.The three-dimensional modeling method using static fixed-point three-dimensional laser scanning and vehicle-mounted scanning system technology lacks the top texture information of historical buildings and is costly.Although the use of drone tilt photogrammetry technology can quickly,easily and effectively obtain the relative position of ancient buildings,part of the facade and top structure and building texture information,but the face of narrow streets and lanes has large deformation and texture The quality cannot meet the requirements.In response to these shortcomings,the project uses aerial aerial photography and ground photography to combine the aerial image and the ground image to solve,thereby forming a high-precision historical building model.
