Syntax

plot(model)
plot(model,'Parent',ax)

Description

H = plot(model) plots a cylinder within the axis limits of the current figure. H is the handle to surf, a 3-D shaded surface plot.

H = plot(model,'Parent',ax) additionally specifies an output axes.

title('Detect a Cylinder in a Point Cloud')

Set the maximum point-to-cylinder distance (5 mm) for the cylinder fitting.

maxDistance = 0.005;

Set the region of interest to constrain the search.

roi = [0.4,0.6;-inf,0.2;0.1,inf];
sampleIndices = findPointsInROI(ptCloud,roi);

Set the orientation constraint.

referenceVector = [0,0,1];

Detect the cylinder in the point cloud and extract it.

model = pcfitcylinder(ptCloud,maxDistance,referenceVector,...
        'SampleIndices',sampleIndices);

Plot the cylinder.
