目录
1.新建工程
2.文件及属性配置
2.1文件拷贝
2.2VS项目属性配置
2.2.1包含目录和库目录添加
2.2.2附加依赖项添加
3.添加基于官方mfc代码改写的CGXBitmap类
3.1添加CGXBitmap类
3.2编写CGXBitmap.h和.cpp文件
4.编写Qt .h和 .cpp文件
5.运行效果
6.下载链接
7.双相机代码移植Qt版
1.新建工程
该项目是通过阅读大恒官方C++项目的代码进行移植的一个Qt简单demo，废话不多说直接上步骤。
至此一个Qt项目创建完毕。
2.文件及属性配置
因为需要使用大恒官方的API，那么就需要使用官方提供的库文件和头文件。可以通过该步骤添加到项目中。（方法不唯一，这里为了移植到其他电脑才这样做的）
2.1文件拷贝
2.2VS项目属性配置
2.2.1包含目录和库目录添加
2.2.2附加依赖项添加
至此整个项目的属性配置和文件就配置完成了。
3.添加基于官方mfc代码改写的CGXBitmap类
CGXBitmap类是我基于大恒官方提供的C++代码中mfc版CGXBitmap类改写的。具体功能有：显示图像、保存图像等功能。具体步骤如下：
3.1添加CGXBitmap类
3.2编写CGXBitmap.h和.cpp文件
在添加的CGXBitmap.h 填写如下内容
//
/*CGXBitmap.h*/

编写daheng_SingleCam_for_qt.h(我的界面是用代码生成的，没有使用拖曳的方式生成，目的是为了提供更好的代码观感)
