IMcSpatialCalibSetPointMapping Method

Set a spatial calibration mapping via a set of points. A set of points, and their corresponding calibrated values, are used to define a polynomial mapping of the type described in SetPolynomialMapping.

Copy
Sub SetPointMapping ( 
	DegreeX As Integer,
	DegreeY As Integer,
	Points As Object,
	NumPoints As Integer
)

Parameters

DegreeX
Type: SystemInt32
The required polynomial degree in X. Enough points must be provided.
DegreeY
Type: SystemInt32
The required polynomial degree in Y. Enough points must be provided
Points
Type: SystemObject
An array of doubles in the following format: P1.x, P1.y, P2.x, P2.y,..., P1'.x, P1'.y, P2'x...
NumPoints
Type: SystemInt32
The number of pairs of points (raw + calibrated) in Points. I.e. NumPoints = 3 means that Points contains 3 uncalibrated points and their 3 calibrated values. In all, it's 12 values.

Return Value

Type: 
HRESULT
Remarks
The number of points required to generate a polynomial mapping of degrees DegreeX,DegreeY is equal to (DegreeX+1) x (DegreeY+1). For instance, a second degree mapping will require at least nine points and their calibrated equivalents. A uniform linear mapping (partial polynomial of degree one) will require at least two points.
