我不确定问题是什么,但是当我在网络摄像头上移动时,它会抓住我的脸,但它不是我的动作的镜子,它是向后/倒置的。
有谁知道如何解决这个问题?
def网络摄像头(网络摄像头,分类器,downScale):
if webcam.isOpened():
rval, frame = webcam.read()
else:
rval = False
while rval:
# detect faces and draw bounding boxes
minisize = (frame.shape[1]/downScale,frame.shape[0]/downScale)
miniframe = cv2.resize(frame, minisize)
faces = classifier.detectMultiScale(miniframe)
for f in faces:
x, y, w, h = [ v*downScale for v in f ]
cv2.rectangle(frame, (x,y), (x+w,y+h), (0,0,255))
cv2.putText(frame, "Press ESC to close.", (5, 25),
cv2.FONT_HERSHEY_SIMPLEX, 1.0, (255,255,255))
cv2.imshow("Face Crop", frame)
# get next frame
rval, frame = webcam.read()
key = cv2.waitKey(10)
if key in [27, ord('Q'), ord('q')]: # exit on ESC
break
