Parameters
- objectPoints
- Type: Emgu.CV.StructureMCvPoint3D32f
The array of object points - imagePoints
- Type: System.DrawingPointF
The array of corresponding image points - intrinsicMatrix
- Type: Emgu.CVIInputArray
The camera matrix (A) [fx 0 cx; 0 fy cy; 0 0 1]. - distortionCoeffs
- Type: Emgu.CVIInputArray
The vector of distortion coefficients, 4x1 or 1x4 [k1, k2, p1, p2]. If it is IntPtr.Zero, all distortion coefficients are considered 0's. - rotationVector
