Jadewyh / HKCameraDev

Provide easy use of HKVision SDK

Dependencies

1. Reference MvCameraControl.Net.dll, halconDotNet.dll in both projects
2. halcon.dll and hcanvas.dll should be present in the UI project's binary directory

Basic workflow

1. Call HKCameraManager.ScanForAttachedCameras and all attached cameras will be available via HKCameraManager.AttachedCameras
2. The class CameraViewModel asbstract functionality of a HKCamera and provide 4 major APIs:

var camera1 = HKCameraManager.AttachedCameras[0];

camera1.ImageAcquired += image =>{
    //Your image processing logic here
};
// Open the camera
camera1.Open();
// Start grabbing
camera1.GrabStart();
// Stop grabbing
camera1.GrabStop();
// Close camera
camera1.Close();

3. Real time mode and trigger source demo

// Turn off continuous mode
camera1.RealTimeMode = false;
// Set trigger source to software
camera1.TriggerSourceType = CameraTriggerSourceType.Software
// Software trigger
camera1.SoftwareExecuteOnce();

For WPF users that follow MVVM pattern, the following bindings help you manage all the camera logics

1. Command bindings

  public ICommand SoftwareExecuteOnceCommand { get; }
  public ICommand OpenCameraCommand { get; }
  public ICommand CloseCameraCommand { get; }
  public ICommand GrabStartCommand { get; }
  public ICommand GrabStopCommand { get; }
  public ICommand ToggleTriggerSourceCommand { get; }

2. Property bindings

        /// <summary>
        /// Toggle grab start and stop
        /// </summary>
        public bool IsGrabbing
        {
            get { return _isGrabbing; }
            set
            {
                _isGrabbing = value;
                // Do not do anything meaningful before construction finished
                if (value) GrabStart();
                else GrabStop();
            }
        }

        /// <summary>
        /// Trigger source
        /// </summary>
        public CameraTriggerSourceType TriggerSourceType
        {
            get { return _triggerSourceType; }
            set
            {
                if (value == CameraTriggerSourceType.None) return;
                _triggerSourceType = value;
                uint flag = (uint) (value == CameraTriggerSourceType.Line0 ? 0 : 7);
                _myCamera.MV_CC_SetEnumValue_NET("TriggerSource", flag);
            }
        }

        /// <summary>
        /// True to realtime mode
        /// False to trigger mode
        /// </summary>
        public bool RealTimeMode    
        {
            get { return _realTimeMode; }
            set
            {
                _realTimeMode = value;
                uint flag = (uint) (value ? 0: 1);
                _myCamera.MV_CC_SetEnumValue_NET("TriggerMode", flag);
                if (value) return;
                // If realtime is off, reactivate trigger source
                ReactivateTriggerSource();
            }
        }
