Visualize Point Cloud Sequence

Open Script

This example shows how to visualize a streaming point cloud sequence by using a Point Cloud Viewer block.

Load the location data for a point cloud sequence into the MATLAB® workspace.

load("pcLocationSeq.mat")

Load the color data for the point cloud sequence into the MATLAB workspace.

load("pcColorSeq.mat")

Example Model

Open the Simulink® model.

modelname = "ex_blkpointcloudviewer.slx";
open_system(modelname)

The model reads the point cloud sequence location data from the MATLAB workspace using a Video From Workspace block with these parameters:

  • Signal — pcLocationSeq.mat

  • Sample Time — 1

The model reads the point cloud sequence color data from the MATLAB workspace using a Video From Workspace block with these parameters:

  • Signal — pcColorSeq.mat

  • Sample Time — 1

The Image output ports of the Video From Workspace blocks send the location and color information of the 3-D point cloud sequence, frame by frame, to the Location and Color ports, respectively, of the Point Cloud Viewer block.

Simulate the model

Run the model and display the streaming 3-D point cloud sequence in the Point Cloud Viewer window.

sim(modelname);
