如何使用OpenCV中SIFT提取的特征在目标对象周围获取矩形 [英] How to get a rectangle around the target object using the features extracted by SIFT in OpenCV

问题描述

我正在OpenCV中进行对象检测项目，该项目包括将模板图像中的对象与参考图像进行匹配.使用SIFT算法可以准确地检测和匹配特征，但是我希望重新匹配匹配的特征 我的算法使用KD-Tree est ean First技术获取匹配项

I'm doing project in OpenCV on object detection which consists of matching the object in template image with the reference image. Using SIFT algorithm the features get acurately detected and matched but I want a rectagle around the matched features My algorithm uses the KD-Tree est ean First technique to get the matches

推荐答案

如果要在检测到的对象周围放置一个矩形，请在这里，您将获得与此完全相同的代码示例.您只需在单应性H周围绘制一个矩形.

If you want a rectangle around the detected object, here you have code example with exactly that. You just need to draw a rectangle around the homography H.

希望它会有所帮助.祝你好运.

Hope it helps. Good luck.
