ProjectPoints2 Method (objectPoints, extrin, intrin, mats)
NamespacesEmgu.CVCameraCalibrationProjectPoints2(array<MCvPoint3D32f>[]()[], ExtrinsicCameraParameters, IntrinsicCameraParameters, array<Matrix<(Of <(Single>)>)>[]()[])

Computes projections of 3D points to the image plane given intrinsic and extrinsic camera parameters. Optionally, the function computes jacobians - matrices of partial derivatives of image points as functions of all the input parameters w.r.t. the particular parameters, intrinsic and/or extrinsic. The jacobians are used during the global optimization in cvCalibrateCamera2 and cvFindExtrinsicCameraParams2. The function itself is also used to compute back-projection error for with current intrinsic and extrinsic parameters.

objectPoints (array< MCvPoint3D32f >[]()[])
The array of object points, 3xN or Nx3, where N is the number of points in the view
extrin (ExtrinsicCameraParameters)
extrinsic parameters
intrin (IntrinsicCameraParameters)
intrinsic parameters
mats (array< Matrix<(Of <(Single>)>) >[]()[])
Optional matrix supplied in the following order: dpdrot, dpdt, dpdf, dpdc, dpddist
Return Value
The array of image points which is the projection of objectPoints
Note, that with intrinsic and/or extrinsic parameters set to special values, the function can be used to compute just extrinsic transformation or just intrinsic transformation (i.e. distortion of a sparse set of points)
