针对倾斜影像数据处理、三维重建中存在的关键问题,对倾斜影像三维重建技术的发展方向、难点、解决思路进行了总结。机载倾斜摄影测量是近年来发展最快也是最有影响力的测绘技术之一,为地面目标的快速三维重建提供了有效的数据保障。寻求可行的数据处理方法,实现数据处理的自动化,提升三维重建的精度和速度,是倾斜影像三维重建处理的关键问题。该文首先对倾斜影像的三维重建技术进行了介绍,对三维重建中核心技术影像匹配等近些年的发展进行了探讨,并结合近些年多数据源融合的发展趋势,对联合地面影像、激光雷达数据与倾斜影像进行大范围场景的精细三维重建技术进行了阐述,对其中涉及到的难点进行了分析,最后对利用倾斜影像进行自动化三维建模技术的发展进行了总结。
The developments,difficulties and solved methods of airborne oblique photogrammetry are introduced in this paper. Airborne oblique photogrammetry has been one of the most influential mapping technologies in recent years, which provided effective data protection for rapidly 3 D reconstruction of ground targets. It is one of key problems to find a feasible method for data processing,realize the automatic data processing and improve the accuracy and speed of 3 D reconstruction. In this paper, the oblique images-based 3 D reconstruction methods are introduced first, and then the development of the key technologies of 3 D reconstruction and image matching is discussed in this paper. Based on the trend of multi-source data fusion,the outdoor sense accurate reconstruction methods are elaborated combining the terrestrial based data,LiDAR data and oblique image,and the difficulties are analyzed which are involved in these works. Finally,the development of the oblique images based3 D modeling technology is summarized and some suggestions for the development, difficulties and solution of the 3 D reconstruction of oblique image are given.
