【摘要】：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%。
[Abstract]:Aiming at the problem that panoramic images can not provide the geospatial information of objects in the scene, this paper proposes a method to measure the objects of remote interest points in panoramic images by constructing stereoscopic panorama. The existing measurement methods based on stereo vision are mainly used to measure close distance objects. For objects with a long distance (such as more than 100 m), it is difficult to obtain accurate results by using a non-measuring camera without control points. The proposed method not only acquires panoramic image, but also uses GPS/INS sensor to obtain position and attitude information of camera. In the process of subsequent data processing, the method of setting initial value in relative orientation is improved. The accurate measurement of long range target in panoramic image is realized. The experimental results show that the relative accuracy of the measurement results can reach 1 / 10 of the distance between the camera and the target.
