我正在尝试使用python和Open Cv实现人脸识别。通过遵循一些可用的教程及其正常工作,我已经成功地使用python实现了人脸检测。
现在我想做的是做人脸识别,我只听了一些教程,但是没有一个对我有用。
我已经看了很清楚的本教程,但是那里的代码引发了语法错误。

我试图运行此代码
import cv
cv.NamedWindow(“w1”, cv.CV_WINDOW_AUTOSIZE)
camera_index = 0
capture = cv.CaptureFromCAM(camera_index)
def repeat():
global capture #declare as globals since we are assigning to them now
global camera_index
frame = cv.QueryFrame(capture)
cv.ShowImage(“w1″, frame)
c = cv.WaitKey(10)
if(c==”n”): #in “n” key is pressed while the popup window is in focus
camera_index += 1 #try the next camera index
capture = cv.CaptureFromCAM(camera_index)
if not capture: #if the next camera index didn’t work, reset to 0.
camera_index = 0
capture = cv.CaptureFromCAM(camera_index)
while True:
repeat()
但我在第6行出现以下错误
There's an error in your program:expected an intended block.
我尽力解决了这个问题,但没有任何效果。
由于我是树莓派和python的新手,因此我们将不胜感激。
提前致谢。
最佳答案
您可以按照以下方式重新格式化它,看看是否有任何框架。
import cv2.cv as cv
cv.NamedWindow('w1', cv.CV_WINDOW_AUTOSIZE)
camera_index = 0
capture = cv.CaptureFromCAM(camera_index)
def repeat():
global capture #declare as globals since we are assigning to them now
global camera_index
frame = cv.QueryFrame(capture)
if frame:
cv.ShowImage('w1', frame)
c = cv.WaitKey(10)
if(c=='n'): #in “n” key is pressed while the popup window is in focus
camera_index += 1 #try the next camera index
capture = cv.CaptureFromCAM(camera_index)
if not capture: #if the next camera index didn’t work, reset to 0.
camera_index = 0
capture = cv.CaptureFromCAM(camera_index)
while True:
repeat()
