basler相机增益代码

以下是基于 Basler Pylon SDK 的示例代码，用于获取和设置相机增益参数：

1. 初始化 Pylon SDK

#include <pylon/PylonIncludes.h>

using namespace Pylon;

PylonInitialize();

2. 获取相机列表和打开相机

// Get the transport layer factory.
CTlFactory& tlFactory = CTlFactory::GetInstance();

// Get all attached devices and exit application if no device is found.
DeviceInfoList_t devices;
if (tlFactory.EnumerateDevices(devices) == 0)
{
    throw RUNTIME_EXCEPTION("No camera present.");
}

// Create an instant camera object for the first available device.
CInstantCamera camera(tlFactory.CreateDevice(devices[0]));

// Open the camera.
camera.Open();

3. 获取和设置相机增益参数

获取参数：

// Get the currently set gain value.
double gainValue = camera.Gain.GetValue();

设置参数：

// Set the gain value to 10.
camera.Gain.SetValue(10.0);

4. 关闭相机和释放资源

// Close the camera.
camera.Close();

// Releases all pylon resources.
PylonTerminate();

注意：以上代码仅供参考，具体的参数和操作方式可能因相机型号和需求而异。建议参考相应型号的 Basler 官方文档和示例代码。
