建立人脸识别数据集

Question

from imutils.video import VideoStream
import argparse
import imutils
import time
import cv2
import os
import sys


ap = argparse.ArgumentParser()
ap.add_argument("-c" "/-- 
cascade/Haarcascade_frontalface_default.xml",required=True,
            help="path to where the face cascade resides")
ap.add_argument("-o" "/--datasets/andrian",
            help="path to your output",required=True)
args = vars(ap.parse_args())


 detector=cv2.CascadeClassifier(args["C/users/fridah/pycharmprojects/attendance_system/ cascade"])


print("[INFO] starting video stream...")
vs = VideoStream(src=0).start()

time.sleep(2.0)
total = 0


while True:

    frame = vs.read()
    orig = frame.copy()
    frame = imutils.resize(frame, width=400)


    rects = detector.detectMultiScale(
            cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY), scaleFactor=1.1,
            minNeighbors=5, minSize=(30, 30))

    # loop over the face detections and draw them on the frame
    for (x, y, w, h) in rects:
        cv2.rectangle(frame, (x, y), (x + w, y + h), (0, 255, 0), 2)


    cv2.imshow("Frame", frame)
    key = cv2.waitKey(1) & 0xFF

    if key == ord("k"):
        p = os.path.sep.join([args["output"], "{}.png".format(
            str(total).zfill(5))])
        cv2.imwrite(p, orig)
        total += 1


    elif key == ord("q"):
        break

print("[INFO] {} face images stored".format(total))
print("[INFO] cleaning up...")
cv2.destroyAllWindows()
vs.stop()

一旦我尝试运行该程序，它就会给出以下错误：我已经尝试修复，请您帮忙吗？arg解析器每次都会给出错误 数据集.py：错误：需要以下参数：-c /- 级联/Haarcascade_frontalface_default.xml，-o /-datasets / andrian
