在机器视觉应用领域里特征检测和匹配是一个很重要的算法，比如图像配准、跟踪和目标检测。这个例子里，我们用基于特征的方法完成图像拼接。处理的方法是先用图像配准特征点。不同于单图像对配准，这里是多图像对的配准完成图像拼接。(In the field of machine vision application, feature detection and matching is a very important algorithm, such as image registration, tracking and target detection. In this example, we use a feature based method to complete the image stitching. The method of processing is to register the feature points with the image first. Unlike the single image pair registration, this is the registration of the multi image pairs that completes the image stitching.)
