GevCameraControl

Syntax

Constructor:

GevCameraControl(
    OTCID oidITcVnGevImageProvider
)

Methods

Name	Description
ClearImageQueue	Delete all images contained in the TcVnGevImageProvider TcCOM module receive queue and reset the corresponding omitted images counter.
CloseCamera	Close the control channel to the camera.
GetCalibPatternRef	Gets the reference calibration pattern points from the TcVnGevImageProvider TcCOM module (Can be set from the calibration assistant)
GetCameraMatrix	Gets the camera matrix from the TcVnGevImageProvider TcCOM module (requires intrinsic calibration parameters, e.g. set by the calibration assistant)
GetCurrentImage	Gets the current available image (first in receive queue).
GetCurrentImageUndistorted	Gets the current available image (first in receive queue) with undistortion applied. Incompatible with pixel formats that contain an encoding, e.g. a Bayer pattern. Requires intrinsic calibration parameters in the TcVnGevImageProvider TcCOM module, e.g. set by the calibration assistant.
GetCurrentImageWithGvspInfo	Gets the current available image (first in receive queue) and its corresponding GVSP info.
GetCurrentImageWithGvspInfoUndistorted	Gets the current available image (first in receive queue) with its corresponding GVSP info and undistortion applied. Incompatible with pixel formats that contain an encoding, e.g. a Bayer pattern. Requires intrinsic calibration parameters in the TcVnGevImageProvider TcCOM module, e.g. set by the calibration assistant.
GetDistortionCoefficients	Gets the distortion coefficients from the TcVnGevImageProvider TcCOM module (requires intrinsic calibration parameters, e.g. set by the calibration assistant)
GetLastImageFromQueue	Gets the last received image from the queue.
GetOmittedImagesNum	Gets the number of omitted images since the last call of ClearImageQueue(). If the image receive queue in the TcVnGevImageProvider TcCOM module is full and a new image arrives, the first one in the queue will be deleted and the omitted counter is increased.
GetRotationMatrix	Gets the rotation matrix from the TcVnGevImageProvider TcCOM module (requires extrinsic calibration parameters, e.g. set by the calibration assistant)
GetState	Gets the current state of the internal camera control state machine.
GetTranslationVector	Gets the translation vector from the TcVnGevImageProvider TcCOM module (requires extrinsic calibration parameters, e.g. set by the calibration assistant)
InitializeCamera	Initialize the camera to the intended state (includes sending the 'InitCameraCommands' defined in the GevImageAcquisition TcCOM module to the camera).
OpenCamera	Open a control channel to the camera.
Reset	Reset the camera controller to initial state (might require multiple calls depending on current state, until S_OK is returned)
ResetCameraFeatures	Reset the camera features to initial state (sends the 'InitCameraCommands' defined in the GevImageAcquisition TcCOM module to the camera).
SetCameraMatrix	Sets the camera matrix to the TcVnGevImageProvider TcCOM module
SetDistortionCoefficients	Sets the distortion coefficients to the TcVnGevImageProvider TcCOM module
SetRotationMatrix	Sets the rotation matrix to the TcVnGevImageProvider TcCOM module
SetTranslationVector	Sets the translation vector to the TcVnGevImageProvider TcCOM module
StartAcquisition	Send the 'StartAcquisitionCommands' defined in the TcVnGevImageProvider TcCOM module to the camera.
StopAcquisition	Send the 'StopAcquisitionCommands' defined in the TcVnGevImageProvider TcCOM module to the camera.
TriggerImage	Send the 'SoftwareTriggerCommands' defined in the TcVnGevImageProvider TcCOM module to the camera.
