CLsqFit:GetNumPtsUsed
The GetNumPtsUsed method returns the number of points used in computing the fit. This number ignores points that were deleted or rejected from the total number of points added to the sample.
nPts = CLsqFit:GetNumPtsUsed() nPts = CLsqFit:GetNumPtsUsed( nChannel ) n1, n2, n3, n4 = CLsqFit:GetNumPtsUsed() |
nChannel is an optional argument that specifies the channel for multi-channel (RGB) data.
nPts,n1, n2,n3, and n4 are the number of points used for fitting all channels when nChannel is not specified.
The following script fits a 2x2 polynomial with data rejection enabled, then retrieves the number of points used in the fit.
|
-- create a CLsqFit object |
|
-- set 2x2 coefficients to fit a warped plane |
|
-- add a point with x = 3, y = 5, z = 5.15 |
-- add more points to the fit |
|
|
-- enable bad data rejection |
|
-- Fit the polynomial |
|
-- number of points used |
|
-- number of points rejected |
|
-- list the number used and number rejected |
