plot

Plot plane in a figure window

Syntax

plot(model)

plot(model,Name,Value)

Description

H = plot(model) plots a plane within the axis limits of the current figure. H is the handle to the patch.

H = plot(model,Name,Value) includes additional options specified by one or more Name,Value pair arguments.

Examples

Detect Plane in Point Cloud

Load point cloud.

load('object3d.mat');

Display the point cloud.

figure
pcshow(ptCloud)
xlabel('X(m)')
ylabel('Y(m)')
zlabel('Z(m)')
title('Detect a plane in a point cloud')

Set the maximum point-to-plane distance (2cm) for plane fitting.

maxDistance = 0.02;

Set the normal vector of a plane.

referenceVector = [0, 0, 1];

Set the maximum angular distance (5 degrees).

maxAngularDistance = 5;

Detect the table in the point cloud and extract it.

model = pcfitplane(ptCloud,maxDistance,referenceVector,maxAngularDistance);

Plot the plane.

hold on
plot(model)

Input Arguments

model — Parametric plane model

plane model

Parametric plane model returned by planeModel.

Name-Value Pair Arguments

Specify optional comma-separated pairs of Name,Value arguments. Name is the argument name and Value is the corresponding value. Name must appear inside quotes. You can specify several name and value pair arguments in any order as Name1,Value1,...,NameN,ValueN.

Example: 'Color', 'r'.

'Parent' — Output axes

gca (default) | axes

Output axes, specified as the comma-separated pair of 'Parent' and the current axes for displaying the visualization.

'Color' — Color of the plane

'red' (default) | 1-by-3 RGB vector | short name of color | long name of color

Color of the plane, specified as the comma-separated pair of 'Color' and one of:

• 1-by-3 RGB vector with values in the range of [0 1]

• short name of a MATLAB^® ColorSpec color, such as 'b'

• long name of a MATLAB ColorSpec color, such as 'blue'

Introduced in R2015b
