海康威视相机在QTcreate上的使用教程

前言：

海康威视的教程里面，关于C++的教程，编译环境是VS，所以想使用QTcreate对于海康威视的相机进行使用，包括查找设备，打开设备，关闭设备，开始采集，停止采集，软触发，触发一次，保存bmp，保存jpg，保存tiff，保存png，调节曝光，增益，帧率。

基础夯实：

在MVS中海康威视的相关教程：MVS链接
下载完成之后按照这个目录（我是下载的的D盘），可以找到VS的教程：D:\MVS\Development\Samples\VC\VS
如果你需要QT上的教程，请继续向下观看。

参考的资料：

在这个过程中，我参考了很多的资料，包括VS里面的例程代码，但是我水平有限，不能直接搬运VS中的代码。
资料：参考资料1，参考资料2
简单对资料进行说明，介绍了环境的安装，包括opencv，sdk的头文件，库文件，二次封装的MvCamera.h和MvCamera.cpp文件。环境的安装是极其容易出错的过程，环境没问题，其他的才能正常的运行。

遇到问题：

问题1：int64 does not

这个是你mingw设置的opencv，但是你却用msvc打开了。这个编译环境必须一致。

问题2：LNK2019

你的opencv库没有连接好，路径问题或者camke问题，系统环境问题这都是有可能的。

配置思路(这个很重要)

首先你下载MVS之后，里面lib文件和头文件，头文件全要（参考配置图片），库文件只要一个（MvCameraControl.lib）。你需要把二次封装的函数导入你的QT下面里面，就是MvCamera.h和MvCamera.cpp这两个文件，如果你只进行导入是不可以的，因为你用到了opencv，不要纠结要不要使用opencv，直接用就行了，很方便，当时纠结了，想直接使用那两个文件，一直被卡。opencv按照教程按装就行了，按照mingw那个流程，在QT的pro文件中使用绝对路径，别使用相对路径（不使用导入库那个选项），因为我当时导入库就没成功。头文件直接包含，在直接的文件中导入一下，看一下有没有报错，没有保存说明导入成功。这里的MvCamera.cpp和MvCamera.h是不能直接使用的，需要在里面添加一些内容，直接使用也是会报错，原因就是你使用了opencv。最后，大佬使用的是导入.h文件，我需要ui文件，我就自己进行更改了，如果有需要ui文件的，评论区发qq邮箱，我源码或者ui可以私发你学习。基本上按照这个思路，成功搭建环境到运行应该是没有问题的。
