Question

我需要使用cv2.xfeatures2d.SIFT_create（）函数进行特征检测。我已经下载了open_contrib。但是当使用cmake将额外的模块与open_cv包连接时，我仍然会遇到大量错误。这是我收到的错误消息。

更新现在我将参数FILENAME从文件

更改为PACKAGE

Files that use FILENAME instead of PACKAGE:
opencv_contrib-master/modules/dnn/cmake/OpenCVFindLibProtobuf.cmake
opencv_contrib-master/modules/xfeatures2d/cmake/download_boostdesc.cmake
opencv_contrib-master/modules/xfeatures2d/cmake/download_vgg.cmake

现在我还有两个问题，有人可以帮忙吗？

    CMake Error at /home/darren/Desktop/OpenCV/cmake/OpenCVUtils.cmake:1043 (file):
  file DOWNLOAD cannot open file for write.
Call Stack (most recent call first):

如何删除此错误并让我使用该方法....（我的opencv版本是3.2.0，我的contri包也是3.2.0）

Answer 1

这个问题发生在我身上，重新下载额外的模块解决了我的问题。您是否尝试在运行cmake时设置OPENCV_EXTRA_MODULES_PATH？运行cmake时的-D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib-3.2.0/modules。
