介绍
c# 相机库，含海康、大恒品牌2D相机的常用功能。
底层采用回调+信号量模式封装 ，最大程度减小线程资源，提高采图效率。
开源地址：（整理后贴出）
功能持续完善中。。。
工厂模式创建实例
ICamera myCamera;
myCamera= CamFactory.CreatCamera(CameraBrand.HIK);//CameraBrand.DaHeng
选取对应SN号的相机，初始化
//获取相机枚举
var devicelist = myCamera.GetListEnum();
//or
//var devicelist = CamFactory.GetDeviceEnum(CameraBrand.HIK);
//选对应SN,初始化相机
myCamera.InitDevice(devicelist.First());
启动相机
启动相机有以下几种方式：
- 常规硬触发
- 常规软触发
- 硬触发 + 回调
- 软触发 + 回调
//硬触发模式 启动相机
myCamera.StartWith_HardTriggerModel(HardTriggerModel.Line0);
//软触发模式 启动相机
//myCamera.StartWith_SoftTriggerModel();
//硬触发 + 回调模式 启动相机
// myCamera.StartWith_HardTriggerModel_SetCallback(HardTriggerModel.Line0, CameraCallBack);
//软触发 + 回调模式 启动相机
//myCamera.StartWith_SoftTriggerModel_SetCallback(CameraCallBack);
回调函数：
/// <summary>
/// 回调函数
/// </summary>
/// <param name="bmp"></param>
private void CameraCallBack(Bitmap bmp)
{
//执行取图后的操作
bmp.Save("./test.bmp");
}
取图
//等待硬触发 获取图片, 设定超时：5000ms
myCamera.GetImage(out Bitmap CaptureImage,5000);
//or 使用默认超时时间
//myCamera.GetImage(out Bitmap CaptureImage);
//软触发获取图像
//myCamera.GetImageWithSoftTrigger(out Bitmap CaptureImage);
/// <summary>
/// 回调函数
/// </summary>
/// <param name="bmp"></param>
private void CameraCallBack(Bitmap bmp)
{
//执行取图后的操作
bmp.Save("./test.bmp");
}
注销相机
//注销当前实例
myCamera.CloseDevice();
or
//CamFactory.DestroyCamera(newcamera);
or
//CamFactory.DestroyAll();
参数设置/获取
含常用参数设置和获取
如曝光值、延时、硬触发方式等
