A survey method for objects at a distance is proposed in order to resolve the problem of lacking geospatial information in stereo panorama. The current methods mainly aim at the survey for close range objects, while for a bit far range objects or even for long range objects measurement with a non-metric camera, the accuracy of the result is low if there are no control points provided. In the proposed method, GPS/INS sensors are utilized to acquire the camera’s pose data, and the original values in the relative orientation procedure are set in a new way. As a consequence, objects can be measured much more precisely on the stereo panorama, with the precision up to 1% of the distance between the camera and the objects in the performed experiments.

针对全景影像无法提供场景中目标的地理空间信息问题, 提出一种通过构建立体全景, 实现对全景影像中较远距离兴趣点目标的量测方法。现有的基于立体视觉的量测方法主要实现对近距离物体的量测, 对于较远距离(如 100 m 以上)的物体, 在缺乏控制点的情况下, 使用非量测相机难以获得精确结果。所提方法在获取全景影像的同时, 采用 GPS/INS 传感器获取相机的位置和姿态信息, 在后续数据处理过程中, 通过改进相对定向环节中初始值的设置方法, 实现对全景影像中远距离目标的精确量测。实验表明, 量测结果的相对精度可以达到相机与目标之间距离的1%。
