This code i write on python 3 and open cv3.but its can't show text "Unkonw" from unknow id. Contact: scoutrider6@gmail.com ....Thank you.... import cv2 import numpy as np import os

def assure_path_exists(path): dir = os.path.dirname(path) if not os.path.exists(dir): os.makedirs(dir)

ดึงข้อมูลมากจากLibary opev cv

faceDetect=cv2.CascadeClassifier('haarcascade_frontalface_default.xml');

ใช้กล้อง

cam=cv2.VideoCapture(0);

สร้างไบนารี่

recognizer=cv2.face.LBPHFaceRecognizer_create(); assure_path_exists("recognizer\")

ดึงข้อมูลมาจากไฟล์ Data

recognizer.read('recognizer\OneData.yml')

กำหนดตัวอักษร

font=cv2.FONT_HERSHEY_COMPLEX_SMALL

โปรแกรม(Loop)

while True:

กล้องอ่านค่า
