| 摘 要： | 无序航空影像的三维重建是摄影测量和计算机视觉领域研究的热点问题。提出一种可以不依赖任何辅助信息,由无序航空遥感影像全自动重建三维地形模型的算法流程。实验通过3组具有代表性的影像数据集验证了该方法的有效性和适用性。对重建后的三维地形模型的绝对精度检验表明,该方法重建的三维模型不仅具有较高的平面精度,而且当影像的基高比较好时,也可以获得较高的高程精度。

| Abstract: | The reconstruction of camera orientations and structure from unordered image datasets is a hot issue in photogrammetry and computer vision.An algorithm to reconstruct the 3D terrain model automatically by the aerial images without any auxiliary information is proposed in the paper.The effectiveness and applicability of the proposed method are verified by experiments on three representative image datasets.Absolute accuracy analysis shows that the proposed 3D model reconstructed method has high planimetric accuracy and can get high vertical accuracy on condition of better image baseline. |
