标签: python-3.x cv2

我在python 3.7上使用以下代码

import cv2
import numpy as np

face_cascade = cv2.CascadeClassifier('D:\\ET\\haarcascade_frontalface_default.xml')
eye_cascade = cv2.CascadeClassifier('D:\\ET\\haarcascade_eye.xml')

cap = cv2.VideoCapture(0)

while True:
    ret, img = cap.read()
    gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

    faces = face_cascade.detectMultiScale(gray, 1.3, 5)

    for (x,y,w,h) in faces:
        cv2.rectange(img,(x,y),(x+w,y+h),(255,0,0),2)
        roi_gray = gray[y:y+h, x:x+w]
        roi_color = img[y:y+h, x:x+w]
        eyes = eye_cascade.detectMultiScale(roi_gray)
        for (ex,ey,ew,eh) in eyes:
            cv2.rectangle(roi_color,(ex,ey), (ex+ew,ey+eh),(0,255,0),2)

    cv2.imshow('img',img)
    k = cv2.waitKey(30) & 0xFF
    if k == 27:
        break

cap.release()
cv2.destroyAllWindows()

已安装以下内容:

opencv-contrib-python-3.4.4.19

答案 0 :(得分:1)

错误告诉您cv2没有叫做rectange的东西,但是确实有叫做rectangle的东西。您拼写错误:

cv2.rectange(img,(x,y),(x+w,y+h),(255,0,0),2)
