1、获取相机列表

ModuleInfoList moduleInfoList = VmSolutionMain.GetAllModuleList();
if (moduleInfoList.nNum > 0)
{List<string> cameraModuleNames = moduleInfoList.astModuleInfo.Where(a => !string.IsNullOrEmpty(a.strDisplayName) && "GlobalCameraModule".Equals(a.strModuleName)).Select(a => a.strDisplayName).ToList();cmbCameraName.DataSource = cameraModuleNames;cmbCameraName.SelectedIndex = cameraModuleNames.Count > 0 ? 0 : -1;
}// 获取相机对象
//GlobalCameraModuleTool cameraModuleTool = (GlobalCameraModuleTool)VmSolutionMain["相机名"];  // 方式一
//if(VmSolutionMain["相机名"] is GlobalCameraModuleTool cameraModuleTool){ } else{  // 提示未找到相机'相机名'} // 方式二

2、获取相机参数

GlobalCameraModuleTool对象中的参数目前只能获取，修改后保存不了。

（1）方式一(不推荐)

只有当相机拍过照后获取才是正常的，不然代码报错。海康的问题。

//bool bIsCameraConnect = moduleTool.bIsCameraConnect();          // 连接状态
//GlobalCameraParam globalCameraParam = moduleTool.ModuParams;    // 相机参数
//string cameraSN = globalCameraParam.GetChosenCameraSN();        // 相机SN
//var cameraInfoList = globalCameraParam.GetCameraInfoList();
//string cameraModel = cameraInfoList.nNum > 0 ? cameraInfoList.astCameraInfo[0].strCameraName : string.Empty;  // 相机型号
//string cameraMold = globalCameraParam.CameraMold.ToString();    // 相机类型
//string gammaEnable = globalCameraParam.GammaEnable.ToString();      // 伽马使能
//GammaSelectorEnum gammaSelector = globalCameraParam.GammaSelector;  // 伽马选择器
//double exposureTime = globalCameraParam.ExposureTime;               // 曝光时间
//double gain = globalCameraParam.Gain;                               // 增益
//string gama = string.Empty;
//cameraModuleTool.ModuParams.GetParamValue("Gamma", ref gama);       // 伽马
//gama = gama.Split('$')[0];
//int width = globalCameraParam.Width;                   // 图像宽度
//int height = globalCameraParam.Height;                 // 图像高度
//int triggerSource = globalCameraParam.TriggerSource;   // 触发源
//double triggerDelay = globalCameraParam.TriggerDelay;  // 延迟触发

（2）方式二(目前推荐用)

if (VmSolutionMain[cameraName] is GlobalCameraModuleTool cameraModuleTool)
{
#region 获取参数 cameraModuleTool

var cameraInfoList = globalCameraParam.GetCameraInfoList();
string cameraModel = cameraInfoList.nNum > 0 ? cameraInfoList.astCameraInfo[0].strCameraName : string.Empty;  // 相机型号string cameraMold = globalCameraParam.CameraMold.ToString();  // 相机类型；CommonCamera普通相机、SmartCamera智能相机、DalsaCamera线阵相机

// 伽马(兼容相机未拍照的情况)
string gama = string.Empty;

gama = gama.Split('$')[0];// 像素格式(兼容相机未拍照的情况)
string pixelFormat = string.Empty;
