人臉識別 OpenCV Python

Question

伙計們，我在 python 中遇到 FaceRec 問題，請幫忙

main.py = https://pastebin.com/ST7DzBn4
simpleFaceRec = https://pastebin.com/a6aUVUbD

錯誤：

Traceback (most recent call last):
  File "E:\Documents\Python\FaceRecognitionOS\main.py", line 16, in <module>
    face_locations, face_names = sfr.detect_known_faces(frame)
  File "E:\Documents\Python\FaceRecognitionOS\simple_facerec.py", line 47, in detect_known_faces
    small_frame = cv2.resize(frame, (0, 0), fx=self.frame_resizing, fy=self.frame_resizing)
cv2.error: OpenCV(4.5.5) D:\a\opencv-python\opencv-python\opencv\modules\imgproc\src\resize.cpp:4052: error: (-215:Assertion failed) !ssize.empty() in function 'cv::resize'

Answer 1

在第 9 行更改此內容：

cap = cv2.VideoCapture(2)

到：

cap = cv2.VideoCapture(0)

還有第 12 行：

while True:

到：

while cap.isOpened()
