用 pyqt5给深度学习目标检测+跟踪(yolov3＋siamrpn)搭建界面(3)_结合pyqt的操作界面,实现行人的标记和识别功能

本次的改进与前面两次变动很大，加入了登录与注册界面，检测跟踪界面也重新规划，界面进行了美化，加入了界面跳转功能等等。先上图

检测跟踪界面目前只实现打开摄像头这个功能，后续更新其他功能。

登录界面程序

    return USER_PWD
    
class LoginPane(QWidget, Ui_Form):
    show_register_pane_signal = pyqtSignal()
    show_login_in_signal = pyqtSignal()

    def __init__(self, parent=None, *args, **kwargs):
        super().__init__(parent, *args, **kwargs)
        self.setAttribute(Qt.WA_StyledBackground, True)
        self.setupUi(self)

    def login(self):
        if self.username_ld.text() and self.password_ld.text():
            self.login_in_btn.setEnabled(True)

            self.show_login_in_signal.emit()
        else:
            QMessageBox.critical(self, 'Wrong', '帐号密码错误!')

        self.username_ld.clear()
        self.password_ld.clear()

    def sign_in(self):

每个界面的程序都可以单独运行。主程序可以完整运行所有界面，并实现界面跳转。界面用qtdesigner设计，生成的py文件就不上传。
