我正在尝试为对象检测创建一个 Haar 分类器，我正在关注 Mac 的下一个教程： https ://github.com/mrnuget/opencv-haar-classifier-training
当我开始执行第 5 步时。我在终端上得到以下输出，但没有创建正样本：
opencv_createsamples -bgcolor 0 -bgthresh 0 -maxxangle 1.1 -maxyangle 1.1 maxzangle 0.5 -maxidev 40 -w 75 -h 75 -img ./positive_images/63.jpg -bg tmp -vec samples/63.jpg.vec -num 16 opencv_createsamples - bgcolor 0 -bgthresh 0 -maxxangle 1.1 -maxyangle 1.1 maxzangle 0.5 -maxidev 40 -w 75 -h 75 -img ./positive_images/77.jpg -bg tmp -vec samples/77.jpg.vec -num 16 opencv_createsamples -bgcolor 0 -bgthresh 0 -maxxangle 1.1 -maxyangle 1.1 maxzangle 0.5 -maxidev 40 -w 75 -h 75 -img ./positive_images/88.jpg -bg tmp -vec samples/88.jpg.vec -num 16 opencv_createsamples -bgcolor 0 -bgthresh 0 -maxxangle 1.1 -maxyangle 1.1 maxzangle 0.5 -maxidev 40 -w 75 -h 75 -img ./positive_images/89.jpg -bg tmp -vec samples/89.jpg.vec -num 16 opencv_createsamples -bgcolor 0 -bgthresh 0 - maxxangle 1.1 -maxyangle 1.1 maxzangle 0.5 -maxidev 40 -w 75 -h 75 -img 。/positive_images/76.jpg -bg tmp -vec samples/76.jpg.vec -num 16 ...
我应该提到的是，当我有 OpenCV 3.4 时它可以工作，但现在我有 OpenCV 4。如果您认为这可能是问题，请告诉我如何安装 OpenCV 3.4，因为我尝试过我总是安装 OpenCV 4代替。
