findPointsInModel

Find points enclosed by cuboid model

Renamed from findPointsInsideCuboid in R2024a

Syntax

indices = findPointsInModel(model,ptCloudIn)

Description

indices = findPointsInModel(model,ptCloudIn) returns the linear indices of the points enclosed by a cuboid model, model, in an input point cloud, ptCloudIn.

Examples

Extract Points Inside Cuboid Model

Extract points enclosed by a cuboid model in a point cloud. Create the cuboid model as a cuboidModel object.

Read point cloud data into the workspace.

ptCloudIn = pcread('highwayScene.pcd');

Define a cuboid model as a cuboidModel object.

params = [11.4873085 8.59969 -1.613766 3.6712 1.3220...
    1.75755, 0, 0, 0.017451];
model = cuboidModel(params);

Find the points inside the cuboid.

indices = findPointsInModel(model,ptCloudIn);

Select the corresponding points in the input point cloud.

cubPtCloud = select(ptCloudIn,indices);

Plot the point cloud and the points enclosed by the cuboid.

Input Arguments

model — Cuboid model

cuboidModel object

Cuboid model, specified as a cuboidModel object.

ptCloudIn — Point cloud

pointCloud object

Point cloud, specified as a pointCloud object.

Output Arguments

indices — Indices of enclosed points

N-element column vector

Indices of enclosed points, returned as an N-element column vector. N is the number of enclosed points. Use the select function to select the corresponding points in the input point cloud ptCloudIn.

R2024a: Renamed from findPointsInsideCuboid

The findPointsInsideCuboid function is now called findPointsInModel. The behavior remains the same.
