Description

hrPrev

HRESULT

HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.)

ipSrcPoints

ITcVnContainer*

Container with source point coordinates (ContainerType_Vector_TcVnPoint2_REAL or ContainerType_Vector_TcVnPoint2_DINT)

ipDestPoints

ITcVnContainer*&

Returns a container with the transformed point coordinates (ContainerType_Vector_TcVnPoint2_REAL)

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
