【摘要】：針對全景影像無法提供場景中目標(biāo)的地理空間信息問題,提出一種通過構(gòu)建立體全景,實現(xiàn)對全景影像中較遠距離興趣點目標(biāo)的量測方法�，F(xiàn)有的基于立體視覺的量測方法主要實現(xiàn)對近距離物體的量測,對于較遠距離(如100 m以上)的物體,在缺乏控制點的情況下,使用非量測相機難以獲得精確結(jié)果。所提方法在獲取全景影像的同時,采用GPS/INS傳感器獲取相機的位置和姿態(tài)信息,在后續(xù)數(shù)據(jù)處理過程中,通過改進相對定向環(huán)節(jié)中初始值的設(shè)置方法,實現(xiàn)對全景影像中遠距離目標(biāo)的精確量測。實驗表明,量測結(jié)果的相對精度可以達到相機與目標(biāo)之間距離的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.
