I found the problem . You can Download opencv3.2.0 and opencv_contrib3.2.0 Then use -DOPENCV_EXTRA_MODULES_PATH=/modules Flag to add opencv_contrib to the opencv. The problem is the some files in repositories have incorrect md5.you should download it manually from https://github.com/opencv/opencv_3rdparty/commit/fccf7cd6a4b12079f73bbfb21745f9babcd4eb1d and Copy it to itself folder. then Compile it again.
