Implements POSIT algorithm. Image coordinates are given in a camera-related coordinate system. The focal length may be retrieved using camera calibration functions. At every iteration of the algorithm new perspective projection of estimated pose is computed.

static void cvPOSIT(
	IntPtr positObject, 
	IntPtr imagePoints, 
	double focalLength, 
	MCvTermCriteria criteria, 
	IntPtr rotationMatrix, 
	IntPtr translationVector
)

Parameters

positObject
Type: System..::..IntPtr
Pointer to the object structure
imagePoints
Type: System..::..IntPtr
2D array to the object points projections on the 2D image plane, the second dimension must be 2.
focalLength
Type: System..::..Double
Focal length of the camera used
criteria
Type: Emgu.CV.Structure..::..MCvTermCriteria
Termination criteria of the iterative POSIT algorithm. The parameter criteria.epsilon serves to stop the algorithm if the difference is small.
rotationMatrix
Type: System..::..IntPtr
A vector which contains the 9 elements of the 3x3 rotation matrix
translationVector
Type: System..::..IntPtr
Translation vector (3x1)

Remarks

Difference norm between two projections is the maximal distance between corresponding points.
