海康相机opencv，C++调用demo配置记录

opencvCdemo_0">海康相机opencv，C++调用demo配置记录

配置：1.Opencv4.6.0
2.MVS
3.Vs2019

第一章、相关文件

一、demo文件

在安装好mvs后，相应文件夹中，会有样例文件。默认安装mvs的话，文件在目录：

C:\Program Files (x86)\MVS\Development

在这里插入图片描述
Documentations：一些配置教程文档文件，可以参考一下
Samples:一些样例demo
将Samples文件夹下的OpenCV文件夹拷贝出来。

二、依赖文件

将MvCameraControl.lib和MvCameraControl.h文件拷贝到工程目录下。注意MvCameraControl.lib文件有32位和64位两种，根据自己的工程进行选择。

第二章、修改demo代码

Samples中opencv的RawDataFormatConvert.cpp代码是使用OPencv3和vs2008编写的，其中一些调用接口改变了。需要进行修改，修改后的RawDataFormatConvert.cpp代码如下：

#include "MvCameraControl.h"
#include "opencv2/imgproc.hpp"
#include "opencv2/highgui.hpp"
#include <stdio.h>
#include <Windows.h>
#include <process.h>
#include <conio.h>
#include <string.h>unsigned int g_nPayloadSize = 0;enum CONVERT_TYPE
