def init_pipeline(self): self.pipeline = Pipeline() self.engine = 'EN' return

这段代码定义了一个名为 `init_pipeline` 的方法，该方法创建了一个名为 `pipeline` 的 `Pipeline` 对象，并将 `engine` 属性设置为 `'EN'`。然后，该方法返回了一个值，但是代码中没有给出返回值，因此该方法返回值为 `None`。如果您需要更多上下文或代码，请提供更多信息。

        for thread in self.thread_list:
            if not thread.isRunning():
                self.thread_list.remove(thread)

    def chose_dir(self, line_edit, button_type):
        my_thread = MyThread(line_edit, button_type)
        my_thread.finished_signal.connect(self.update_line_edit)
        self.thread_list.append(my_thread)
        my_thread.start()

        self.saved_color_photos = count

    def update_saved_depth_photos_label(self, count):
        self.saved_depth_photos = count
        self.ui.label_6.setText(str(self.saved_depth_photos))

程序运行提示AttributeError: 'MyWindow' object has no attribute 'saved_color_photos'，优化程序class MyWindow(QWidget): def __init__(self): super().__init__() self.thread_list = [] self.image_thread = None self.init_ui() def init_ui(self): self.ui = uic.loadUi("C:/Users/wyt/Desktop/D405界面/intelrealsense1.ui") def open(self): self.profile = self.pipeline.start(self.config) self.is_camera_opened = True self.label.setText('相机已打开') self.label.setStyleSheet('color:green') self.open_btn.setEnabled(False) self.close_btn.setEnabled(True) self.image_thread = ImageThread(self.pipeline, self.color_label, self.depth_label, self.interval, self.color_photo_dir, self.depth_photo_dir, self._dgl) self.image_thread.saved_color_photos_signal.connect(self.update_saved_color_photos_label) self.image_thread.saved_depth_photos_signal.connect(self.update_saved_depth_photos_label) self.image_thread.start() def close(self): self.image_thread.stop() self.pipeline.stop() self.is_camera_opened = False self.label.setText('相机未打开') self.label.setStyleSheet('color:red') self.open_btn.setEnabled(True) self.close_btn.setEnabled(False) print("已保存color_image的数量是：%d" % self.saved_color_photos) print("已保存depth_image的数量是：%d" % self.saved_depth_photos) self.hide() # 将窗口隐藏，而非退出程序

根据错误提示，似乎你在某个地方使用了 `self.saved_color_photos`，但是 `MyWindow` 类中并没有定义这个属性，因此出现了 `AttributeError`。你需要在 `__init__()` 方法中定义 `self.saved_color_photos` 和 `self.saved_depth_photos` 两个属性，例如：

class MyWindow(QWidget):
    def __init__(self):
        super().__init__()
        self.thread_list = []
        self.image_thread = None
        self.saved_color_photos = 0  # 定义 saved_color_photos 属性
        self.saved_depth_photos = 0  # 定义 saved_depth_photos 属性
        self.init_ui()
    
    # 省略其他方法

这样就可以避免出现上述错误了。
