        return im, pred_boxes

检测效果:

4. UI界面开发:

ag平台:4.1 登录界面:

这里写一个简单的登录界面:

import sys
from PyQt5.QtCore import Qt
from PyQt5.QtGui import QPixmap, QFont, QIcon
from PyQt5.QtWidgets import QWidget, QApplication, QLabel, QDesktopWidget, QHBoxLayout, QFormLayout, \
    QPushButton, QLineEdit, QMainWindow


class LoginForm(QMainWindow):

    def __init__(self):
        super().__init__()
        self.initUI()

    def initUI(self):
        """
        初始化UI
        :return:
        """
        self.setObjectName("loginWindow")
        self.setStyleSheet('#loginWindow{background-color:white}')
        self.setFixedSize(650, 300)
        self.setWindowTitle("登录")
        self.setWindowIcon(QIcon('data/logo.png'))

        # 登录表单内容部分
        login_widget = QWidget(self)
        login_widget.move(0, 0)
        login_widget.setGeometry(0, 0, 650, 260)

        hbox = QHBoxLayout()
        # 添加左侧logo
        logolb = QLabel(self)
        logopix = QPixmap("web/logo.png")
        logolb.setPixmap(logopix)
        logolb.setAlignment(Qt.AlignCenter)
        hbox.addWidget(logolb, 1)
        # 添加右侧表单
        fmlayout = QFormLayout()
        lbl_workerid = QLabel("用户名")
        lbl_workerid.setFont(QFont("Microsoft YaHei"))
        led_workerid = QLineEdit()
        led_workerid.setFixedWidth(270)
        led_workerid.setFixedHeight(38)

        lbl_pwd = QLabel("密码")
        lbl_pwd.setFont(QFont("Microsoft YaHei"))
        led_pwd = QLineEdit()
        led_pwd.setEchoMode(QLineEdit.Password)
        led_pwd.setFixedWidth(270)
        led_pwd.setFixedHeight(38)

        self.btn_login = QPushButton("登录")
        self.btn_login.setFixedWidth(270)
        self.btn_login.setFixedHeight(40)
        self.btn_login.setFont(QFont("Microsoft YaHei"))
        self.btn_login.setObjectName("login_btn")
        self.btn_login.setStyleSheet(
            "#login_btn{background-color:#2c7adf;color:#fff;border:none;border-radius:4px;}")
        self.btn_login.clicked.connect(
            lambda : self.close_logui(led_workerid.text(), led_pwd.text())
        )

        fmlayout.addRow(lbl_workerid, led_workerid)
        fmlayout.addRow(lbl_pwd, led_pwd)
        fmlayout.addWidget(self.btn_login)
        hbox.setAlignment(Qt.AlignCenter)
        # 调整间距
        fmlayout.setHorizontalSpacing(20)
        fmlayout.setVerticalSpacing(12)

        hbox.addLayout(fmlayout, 2)

        login_widget.setLayout(hbox)

        self.center()
        self.show()

    def close_logui(self, user, password):
        print('-[INFO] User:{} Password:{}'.format(user, password))
        self.close()

    def center(self):
        qr = self.frameGeometry()
        cp = QDesktopWidget().availableGeometry().center()
        qr.moveCenter(cp)
        self.move(qr.topLeft())


if __name__ == "__main__":
    app = QApplication(sys.argv)
    ex = LoginForm()
    sys.exit(app.exec_())

效果:

4.2 加载界面:

由于 yolov5 模型加载较慢,所以我们需要写一个加载进度界面,核心代码:

def load_data(self, sp):
        for i in range(1, 11):  # 模拟主程序加载过程
            time.sleep(0.5)                   # 加载数据
            sp.showMessage("加载... {0}%".format(
                i * 10), QtCore.Qt.AlignHCenter | QtCore.Qt.AlignBottom, QtCore.Qt.black)
            QtWidgets.qApp.processEvents()  # 允许主进程处理事件
def main(opt):
    '''
    启动PyQt5程序,打开GUI界面
    '''
    app = QApplication(sys.argv)
    splash = QtWidgets.QSplashScreen(QtGui.QPixmap("data/logo.png"))
    splash.showMessage("加载... 0%", QtCore.Qt.AlignHCenter, QtCore.Qt.black)
    splash.show()                           # 显示启动界面
    QtWidgets.qApp.processEvents()          # 处理主进程事件
    main_window = MainWindow(opt)
    main_window.load_data(splash)           # 加载数据
    # main_window.showFullScreen()          # 全拼显示
    app.setStyleSheet(qdarkstyle.load_stylesheet_pyqt5())
    splash.close()
    main_window.show()
    sys.exit(app.exec_())

效果:

4.3 主界面:

主界面首先使用Qt Designer进行布局设计:

完成后导出为 .ui 文件:

然后使用 PyQt5 加载这些文件到代码中,例如:

from PyQt5 import QtWidgets
from PyQt5.QtWidgets import QMainWindow
from PyQt5.uic import loadUi

class DetailLogWindow(QMainWindow):
    def __init__(self, data, parent=None):
        super(DetailLogWindow, self).__init__(parent)
        loadUi("./data/UI/DetailLog.ui", self)
        self.data = data
        self.face_image.setScaledContents(True)
        # self.license_image.setScaledContents(True)
        self.ticket_button.clicked.connect(self.ticket)
        self.initData()

    def ticket(self):
        self.destroy()

    def initData(self):
        self.cam_id.setText(str(self.data['CARID']))
        self.behavior.setText(self.data['CARCOLOR'])

        if self.data['CARIMAGE'] is not None:
            self.face_image.setPixmap(self.data['CARIMAGE'])
        if self.data['LICENSEIMAGE'] is not None:
            self.license_image.setPixmap(self.data['LICENSEIMAGE'])

        self.preson_id.setText(self.data['LICENSENUMBER'])
        self.face_name.setText(self.data['LOCATION'])
        self.rule.setText(self.data['RULENAME'])

        self.close_button.clicked.connect(self.close)
        self.delete_button.clicked.connect(self.deleteRecord)

    def close(self):
        self.destroy()

    def deleteRecord(self):
        qm = QtWidgets.QMessageBox
        prompt = qm.question(self, '', "确定要删除吗?", qm.Yes | qm.No)
        if prompt == qm.Yes:
            self.destroy()
        else:
            pass

即使用:

loadUi(".ui", self)

4.4 美化界面:

现在界面是这样的:

我们可以用一些CSS语句来装饰部件,当然也可以用别人设计好的。

这里使用qdarkstyle来美化界面:

app.setStyleSheet(qdarkstyle.load_stylesheet_pyqt5())

美化后的效果:

5. UI功能开发:

5.1 绑定槽函数:

信号和槽是PyQt编程对象之间进行通信的机制。每个继承自QWideget的控件都支持信号与槽机制。信号发射时(发送请求),连接的槽函数就会自动执行(针对请求进行处理)。

以下为绑定文件选择按钮的槽函数的示例:

  • 点击事件绑定:
self.file_btn.clicked.connect(
            lambda: self.getFile(self.file_edit))  # 文件选择槽函数绑定
  • 文件选择函数:
def getFile(self, lineEdit):
        file_path = QFileDialog.getOpenFileName()[0]
        lineEdit.setText(file_path)  # 获取文件路径
        self.updateCamInfo(file_path)

这样的话点击 file_btn 按钮就会发出信号,从而运行绑定的函数:

5.2 在UI中显示视频:

这里主要是将图像逐帧放置到 QLabel 部件上。

首先我们需要将opencv的图像转为QImage:

def toQImage(self, img, height=800):
        if not height is None:
            img = imutils.resize(img, height=height)
        qformat = QImage.Format_Indexed8
        if len(img.shape) == 3:
            if img.shape[2] == 4:
                qformat = QImage.Format_RGBA8888
            else:
                qformat = QImage.Format_RGB888
        outImg = QImage(
            img.tobytes(), img.shape[1], img.shape[0], img.strides[0], qformat)
        outImg = outImg.rgbSwapped()
        return outImg

定义刷新时执行的函数:

def update_image(self, pt='face.jpg'):
        _, frame = self.vs.read()
        if frame is None:
            return
        frame = imutils.resize(frame, height=800)
        isChecked = {
            'region': self.region_checkbtn.isChecked(),
            'wall': self.wall_checkbtn.isChecked()
        }
        packet = self.processor.getProcessedImage(frame, isChecked, region_bbox2draw=self.region_bbox2draw)

        qimg0 = self.toQImage(packet['frame'], height=None)
        self.live_preview.setPixmap(QPixmap.fromImage(qimg0))

然后绑定计时器,规定每 50ms 刷新一次:

self.timer = QTimer(self)
self.timer.timeout.connect(self.update_image)
self.timer.start(50)

5.3 相应鼠标绘制区域:

这里使用PyQt5预置的响应函数:

def mouseReleaseEvent(self, event):  # 鼠标键释放时调用
        # 参数1:鼠标的作用对象;参数2:鼠标事件对象,用来保存鼠标数据
        self.unsetCursor()
        n = event.button()  # 用来判断是哪个鼠标健触发了事件【返回值:0  1  2  4】
        if n == 1:
            if self.region_checkbtn.isChecked() or self.wall_checkbtn.isChecked():
                x = event.x()  # 返回鼠标相对于窗口的x轴坐标
                y = event.y()  # 返回鼠标相对于窗口的y轴坐标

这样就可以获取到鼠标点击完释放时的位置,从而用来绘制危险区:

5.4 其他细节:

  • 添加menu:
def add_setting_menu(self, settingsMenu):

        speed_menu = QMenu("更改模型", self)
        settingsMenu.addMenu(speed_menu)

        act = QAction('YOLOv3+DarkNet53', self)
        act.setStatusTip('YOLOv3+DarkNet53')
        speed_menu.addAction(act)

        act = QAction('YOLOv3+MobileNetV3', self)
        act.setStatusTip('YOLOv3+MobileNetV3')
        speed_menu.addAction(act)

        direct_menu = QMenu("更改阈值", self)
        settingsMenu.addMenu(direct_menu)

        act = QAction('阈值+0.05', self)
        act.setStatusTip('阈值+0.05')
        direct_menu.addAction(act)

        act = QAction('阈值-0.05', self)
        act.setStatusTip('阈值-0.05')
        direct_menu.addAction(act)


绑定细节框:

self.details_button.clicked.connect(self.showDetails)
def showDetails(self):
        window = DetailLogWindow(self.data, self)
        window.show()
from PyQt5 import QtWidgets
from PyQt5.QtWidgets import QMainWindow
from PyQt5.uic import loadUi

class DetailLogWindow(QMainWindow):
    def __init__(self, data, parent=None):
        super(DetailLogWindow, self).__init__(parent)
        loadUi("./data/UI/DetailLog.ui", self)
        self.data = data
        self.face_image.setScaledContents(True)
        # self.license_image.setScaledContents(True)
        self.ticket_button.clicked.connect(self.ticket)
        self.initData()

    def ticket(self):
        self.destroy()

    def initData(self):
        self.cam_id.setText(str(self.data['CARID']))
        self.behavior.setText(self.data['CARCOLOR'])

        if self.data['CARIMAGE'] is not None:
            self.face_image.setPixmap(self.data['CARIMAGE'])
        if self.data['LICENSEIMAGE'] is not None:
            self.license_image.setPixmap(self.data['LICENSEIMAGE'])

        self.preson_id.setText(self.data['LICENSENUMBER'])
        self.face_name.setText(self.data['LOCATION'])
        self.rule.setText(self.data['RULENAME'])

        self.close_button.clicked.connect(self.close)
        self.delete_button.clicked.connect(self.deleteRecord)

    def close(self):
        self.destroy()

    def deleteRecord(self):
        qm = QtWidgets.QMessageBox
        prompt = qm.question(self, '', "确定要删除吗?", qm.Yes | qm.No)
        if prompt == qm.Yes:
            self.destroy()
        else:
            pass

6. 部署方案:

6.1 端侧视频推流:

可以放在端侧设备上:

6.2 Flask部署:

注意下面并非本项目代码,而是一个图像分类模型Flask部署的代码:

    return jsonify({'status': 0})

            response = make_response(image_data)
