摘　　要：倾斜摄影测量突破了常规摄影测量只从垂直角度对同一物体或地区拍摄影像的局限,通过同一台传感器在很短时间内(如1天或几天内)多次从不同的角度,或是在同一数据采集平台上同时搭载多台传感器,从竖直、前后左右等不同倾斜方向采集影像,将观察者引入符合人眼视觉的,与真实场景相似的虚拟场景。倾斜摄影测量最主要的成果是实景三维模型数据,三维模型数据有很多种数据格式,当前倾斜摄影测量成果常用的三维模型数据格式有OSGB、OBJ、FBX三种数据格式。文章对这三种数据格式进行简要的分析。The tilt photogrammetry breaks through the limitation that conventional photogrammetry only takes pictures of the same object or area from the vertical angle,by using the same sensor in a very short period of time(such as a day or a few days)many times from different angles,or in the same data acquisition platform which is equipped with multiple sensors at the same time,and collects images from different oblique directions such as vertical,front,rear,left,and right,and introduces the observer into a virtual scene that conforms to human vision and is similar to the real scene.The most important result of tilt photogrammetry is real 3D model data.There are many data formats for 3D model data.At present,the 3D model data formats commonly used in tilt photogrammetry are OSGB,OBJ,FBX.This paper gives a brief description of these three data formats.
