提出了一种基于三元向量描述符的图像匹配方法。三元向量描述符由两种不同类型的仿射不变量组成:两个特征点之间的灰度轮廓和这些点的两个协方差矩阵。为了建立点匹配,我们首先将三元组向量描述子的相似性投票为候选匹配,然后用归一化的三角形区域向量来验证匹配,这些区域向量也是仿射不变的。在增强候选匹配的唯一性之后,我们最后采用带极约束的RANSAC来去除异常值。利用该方法可以在宽基线匹配问题上获得正确的匹配结果。通过实例验证了该方法的有效性。
We propose an image matching method using triplet vector descriptor. The triplet vector descriptor consists of two different types of affine invariants: the gray level profile between two feature points and the two covariance matrices of those points. In order to establish point matches, we first vote the similarities of the triplet vector descriptors into candidate matches, and then, we verify the matches by normalized triangular region vectors, which are also affine invariant. After enforcing the uniqueness of the candidate matches, we finally adopt RANSAC with the epipolar constraint for removing outliers. By using our method, we can obtain correct matches on wide baseline matching problems. We show the effectiveness of our method by real image examples.
