Inputs

Name	Type	Description
ipSrcPoints	ITcVnContainer	Container with source point coordinates (ContainerType_Vector_TcVnPoint2_REAL or ContainerType_Vector_TcVnPoint2_DINT)
ipDestPoints	Reference To ITcVnContainer	Returns a container with the transformed point coordinates (ContainerType_Vector_TcVnPoint2_REAL)
hrPrev	HRESULT	HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.)

In/Outputs

Name	Type	Description
aCameraMatrix	TcVnMatrix3x3_LREAL	Camera matrix containing the intrinsic parameters
aDistortionCoefficients	TcVnArray8_LREAL	Lens distortion coefficients [k1, k2, p1, p2, k3, k4, k5, k6]
aNewCameraMatrix	TcVnMatrix3x3_LREAL	Allows additional shifting of the result point coordinates
