|
hrPrev |
HRESULT indicating the result of previous operations (If SUCCEEDED(hrPrev) equals false, no operation is executed.) | |
|
ipSrcPoints3D |
Container with 3D source points (TcVnPoint3_LREAL) | |
|
ipDestPoints2D |
Returns the transformed 2D points (TcVnPoint2_REAL or TcVnPoint2_DINT, depending on bInteger) | |
|
aCameraMatrix |
3x3 camera matrix containing the intrinsic parameters | |
|
aDistortionCoefficients |
Lens distortion coefficients [k1, k2, p1, p2, k3, k4, k5, k6] | |
|
aRotationMatrix |
3x3 rotation matrix | |
|
aTranslationVector |
Translation vector | |
|
bInteger |
bool |
Selects whether the function returns a container of TcVnPoint2_DINT or TcVnPoint2_REAL |
