Python+OpenCV实现实时眼动追踪的示例代码实现实时眼动追踪的示例代码

使用Python+OpenCV实现实时眼动追踪，不需要高端硬件简单摄像头即可实现，效果图如下所示。

项目演示参见：https://www.bilibili.com/video/av75181965/

项目主程序如下：

import sys

import cv2

import numpy as np

import process

from PyQt5.QtCore import QTimer

from PyQt5.QtWidgets import QApplication, QMainWindow

from PyQt5.uic import loadUi

from PyQt5.QtGui import QPixmap, QImage

class Window(QMainWindow):

def __init__(self):

super(Window, self).__init__()

loadUi('GUImain.ui', self)

with open("style.css", "r") as css:

self.setStyleSheet(css.read())

self.face_decector, self.eye_detector, self.detector = process.init_cv()

self.startButton.clicked.connect(self.start_webcam)

self.stopButton.clicked.connect(self.stop_webcam)

self.camera_is_running = False

self.previous_right_keypoints = None

self.previous_left_keypoints = None

self.previous_right_blob_area = None

self.previous_left_blob_area = None

def start_webcam(self):

if not self.camera_is_running:

self.capture = cv2.VideoCapture(cv2.CAP_DSHOW) # VideoCapture(0) sometimes drops error #-1072875772

if self.capture is None:

self.capture = cv2.VideoCapture(0)

self.camera_is_running = True

self.timer = QTimer(self)

self.timer.timeout.connect(self.update_frame)

self.timer.start(2)

def stop_webcam(self):

if self.camera_is_running:

self.capture.release()

self.timer.stop()

self.camera_is_running = not self.camera_is_running

def update_frame(self): # logic of the main loop

_, base_image = self.capture.read()

self.display_image(base_image)

processed_image = cv2.cvtColor(base_image, cv2.COLOR_RGB2GRAY)

face_frame, face_frame_gray, left_eye_estimated_position, right_eye_estimated_position, _, _ = process.detect_face(

base_image, processed_image, self.face_decector)

if face_frame is not None:

left_eye_frame, right_eye_frame, left_eye_frame_gray, right_eye_frame_gray = process.detect_eyes(face_frame,

face_frame_gray,

left_eye_estimated_position,

right_eye_estimated_position,

self.eye_detector)

if right_eye_frame is not None:

if self.rightEyeCheckbox.isChecked():

right_eye_threshold = self.rightEyeThreshold.value()
