cv::xfeatures2d::surf::create 是OpenCV 库中的一个函数,用于创建 SURF(Speeded-Up Robust Features,加速稳健特征)检测器和描述符的实例。SURF 是一种用于图像识别和匹配的特征检测算法,它基于 SIFT(尺度不变特征变换)算法,但进行了优化以提高计算速度。SURF 算法在图像处理和计算机视觉任务中广泛应用于特征点检测...
错误描述:运行cv::xfeatures2d::SURF::create 崩溃,出现Error: The function/feature is not implemented (This algorithm is patented and is excluded in this configuration; Set OPENCV_ENABLE_NONFREE CMake option and rebuild the library) 解决:依据提示 cmake 时,OPENCV_ENABLE_NONFREE 勾上。

最后打开F:\opencv3.4.0\myopencv\install\x86\vc14\lib就会发现已经有opencv_xfeatures2d340d.lib了,将次添加到附加依赖项中就好啦。 ps:一些深层次的原理我不是特别理解,如果大家出现我上面说的情况,那么就可参照,如果情况不同,就还得找其他的方法多试几次啦。
