海康相机SDK C++是一种用于控制海康相机的软件开发包,可以通过C++语言编写程序来实现对海康相机的控制。以下是使用海康相机SDK C++的基本步骤:
1.下载并安装海康SDK,安装好后打开相应的文件夹,这里就是海康相机的软件开发包了。
2.在C++程序中引入SDK的头文件,例如:
```c++
#include "MvCameraControl.h"
```
3.初始化SDK,例如:
```c++
int nRet = MV_OK;
nRet = MV_CC_Init();
if (MV_OK != nRet)
{
printf("MV_CC_Init fail! nRet [%x]\n", nRet);
return nRet;
}
```
4.打开相机,例如:
```c++
MV_CC_DEVICE_INFO_LIST stDeviceList;
memset(&stDeviceList, 0, sizeof(MV_CC_DEVICE_INFO_LIST));
// 枚举设备
nRet = MV_CC_EnumDevices(MV_GIGE_DEVICE | MV_USB_DEVICE, &stDeviceList);
if (MV_OK != nRet)
{
printf("MV_CC_EnumDevices fail! nRet [%x]\n", nRet);
return nRet;
}
// 打开设备
nRet = MV_CC_CreateHandle(&g_hDevHandle, stDeviceList.pDeviceInfo[0]);
if (MV_OK != nRet)
{
printf("MV_CC_CreateHandle fail! nRet [%x]\n", nRet);
return nRet;
}
// 打开设备
nRet = MV_CC_OpenDevice(g_hDevHandle);
if (MV_OK != nRet)
{
printf("MV_CC_OpenDevice fail! nRet [%x]\n", nRet);
return nRet;
}
```
5.设置相机参数,例如:
```c++
// 设置触发模式为软触发
nRet = MV_CC_SetEnumValue(g_hDevHandle, "TriggerMode", MV_TRIGGER_MODE_SOFTWARE);
if (MV_OK != nRet)
{
printf("MV_CC_SetTriggerMode fail! nRet [%x]\n", nRet);
return nRet;
}
// 设置曝光时间
nRet = MV_CC_SetFloatValue(g_hDevHandle, "ExposureTime", 1000);
if (MV_OK != nRet)
{
printf("MV_CC_SetExposureTime fail! nRet [%x]\n", nRet);
return nRet;
}
```
6.开始采集图像,例如:
```c++
// 开始采集
nRet = MV_CC_StartGrabbing(g_hDevHandle);
if (MV_OK != nRet)
{
printf("MV_CC_StartGrabbing fail! nRet [%x]\n", nRet);
return nRet;
}
// 触发一次软触发
nRet = MV_CC_SetCommandValue(g_hDevHandle, "TriggerSoftware");
if (MV_OK != nRet)
{
printf("MV_CC_SetCommandValue fail! nRet [%x]\n", nRet);
return nRet;
}
// 获取图像数据
MV_FRAME_OUT stOutFrame = { 0 };
nRet = MV_CC_GetImageBuffer(g_hDevHandle, &stOutFrame, 1000);
if (MV_OK != nRet)
{
printf("MV_CC_GetImageBuffer fail! nRet [%x]\n", nRet);
return nRet;
}
// 处理图像数据
// ...
// 释放图像缓存
nRet = MV_CC_FreeImageBuffer(g_hDevHandle, &stOutFrame);
if (MV_OK != nRet)
{
printf("MV_CC_FreeImageBuffer fail! nRet [%x]\n", nRet);
return nRet;
}
```
