用已经搭建好face_recognition,dlib 环境来进行人脸识别 未搭建好环境请参考:https://www.cnblogs.com/guihua-pingting/p/12201077.html 使用OpenCV 调用摄像头 importface_recognitionimportcv2 video_capture=cv2.VideoCapture(0)#VideoCapture打开摄像头,0为笔记本内置摄像头,1为外USB摄像头,或写入视频路径mayun_img ...
但是，整体思路是一样的，通过摄像头获取图像信息，然后运行图像处理技术进行人脸检测和人脸识别。OpenCV ...
除非openCV明确写着支持Android，否则它不会自动调用摄像头。opencv本身是对图像处理的工具，自动调用摄像头...
”haarcascade_frontalface_alt2.xml“是opencv已经训练好了的人脸识别样本，VS2010直接调用就可以了，
