+请帮助我生成一个C++编写的Qt UI代码，使用`initUI()`函数实现UI的创建，具体要求如下：
+这个类的签名为`class HikWidget`继承自QWidget
+整个UI分为左右两部分，水平分布比例为3:1，开始时设置窗口大小为1280x720
+左侧为一个QGraphicsView控件，为类成员变量`QGraphicsView *m_gv`，后面如无特殊说明类内成员变量都应当以`m_`开头
+右侧为三个groupbox，这三个groupbox垂直分布，这里可以使用局部变量，从上到下分别显示文字为“相机操作”、“图像保存”、“相机参数”
+“相机操作”groupbox中为一个2x2表格布局，里面有四个pushButton控件，从左到右从上倒下分别显示“打开相机”、“关闭相机”、“开始取流”、“结束取流”
+这几个pushButton声明为成员变量，并根据控件属性和提示文字含义帮我取变量名，例如“打开相机”对应`QPushBotton *m_btn_opencamera`
+“图像保存”groupbox中为一个水平布局，包括一个只读的lineEditor、一个comboBox、两个pushBotton，这四个控件都应该是成员变量
+lineEditor中显示保存文件路径，comboBox选择保存图像格式，至少有`.jpg`, `.png`, `.tif`, `.bmp`几个选项
+两个pushButton显示文字为“打开...”和“保存”，一个负责选择保存路径，一个实际执行保存行为（initUI时不考虑信号与槽）
+最后“相机参数”groupbox中为一个2x2的表格布局，每一行都是一个label和一个doubelSpinBox，其中两个spin应当为成员变量
+第一行的label显示文字“曝光时间：”，对应第一行的spin设置的是曝光时间
+第二行的label显示文字“增益设置：”，对应第二行的spin设置的是增益
+
+---
+
+我希望将图像保存GroupBox修改一下设计，将这个GroupBox修改为2x3表格布局
+第一行3列合并显示m_edit_savePath，第二行分别显示m_cmb_imgFormat、m_btn_openDir、m_btn_saveImage
+
+```cpp
+// 图像保存GroupBox
+QGroupBox *saveGroup = new QGroupBox("图像保存", rightPanel);
+QHBoxLayout *saveLayout = new QHBoxLayout(saveGroup);
+
+m_edit_savePath = new QLineEdit(saveGroup);
+m_edit_savePath->setReadOnly(true);
+m_edit_savePath->setPlaceholderText("保存路径...");
+m_edit_savePath->setClearButtonEnabled(true);
+
+m_cmb_imgFormat = new QComboBox(saveGroup);
+QStringList formats = { ".jpg", ".png", ".tif", ".bmp" };
+m_cmb_imgFormat->addItems(formats);
+
+m_btn_openDir = new QPushButton("打开...", saveGroup);
+m_btn_openDir->setFixedWidth(80);
+
+m_btn_saveImage = new QPushButton("保存", saveGroup);
+m_btn_saveImage->setFixedWidth(80);
+
+saveLayout->addWidget(m_edit_savePath);
+saveLayout->addWidget(m_cmb_imgFormat);
+saveLayout->addWidget(m_btn_openDir);
+saveLayout->addWidget(m_btn_saveImage);
+saveGroup->setLayout(saveLayout);

+
+请使用单例模式帮助我设计一个海康相机的类，类签名为`class HikCamera`
+根据手册，类成员应当有一个句柄指针`void *handler`
+并参考一下我对FLIR相机的时间仿照着设计海康相机类，先仅需要生成头文件`HikCamera.hpp`相关代码即可
+
+```cpp
+// FLIRCamera.hpp
+// 初始化/去初始化相机
+void init();
+void deinit();
+
+// 开始/停止图像采集
+void startGrabing();
+void stopGrabing();
+
+// 设置参数
+void setExposure(double exposure);
+void setGain(double gain);
+
+// 注册图像回调
+void registerImageCallback();
+
+// 线程安全的单例示意代码
+class YourSingleton {
+public:
+    static YourSingleton& getInstance() {
+        static YourSingleton instance;
