| 摘 要： | 近景摄影测量因其拍摄方式灵活，影像之间的相对几何变形大，常导致同名点匹配失败.本文采用SIFT、SURF、FAST+BRIEF和ORB 4种计算机视觉算法，对不同场景和摄影条件下的近景像对进行特征点检测与描述，结合BFMatch和FlannMatch两种方法对特征点实施匹配.实验表明，所用算法的计算耗时越长，匹配结果越好.SIFT、SURF适合于高精度连接点的自动生成，而FAST+BRIEF和ORB可用于相对几何变形小的立体影像密集点匹配.

| Abstract: | Because of flexible shooting mode, the relative geometric deformation between images, one of the main problems of close-range photogrammetry is same name point matching. The SIFT, SURF, FAST + BRIEF, ORB were used to detect and describe the feature points of close-range images under different scenes and photography conditions. The BFMatch and FlannMatch methods were used to match the feature points. Experiments show that the longer the algorithm is, the better the matching result is. SIFT and SURF are both suitable for automatic generation of high-precision connection points. FAST + BRIEF and ORB can be used for stereo image matching with small relative geometric deformation. |
