collapse all

Open Live Script

Create an empty point cloud view set.

vSet = pcviewset;

Load point cloud data.

data = load('livingRoom.mat'); ptCloud1 = data.livingRoomData{1}; ptCloud2 = data.livingRoomData{2};

AddptCloud1to the view set.

absPose1 = rigid3d; vSet = addView(vSet,1,absPose1,'PointCloud',ptCloud1);

AddptCloud2to the view set.

vSet = addView(vSet,2,'PointCloud',ptCloud2);

Estimate the rigid transformation between the two point clouds.

ptCloud2Downsampled = pcdownsample(ptCloud2,'gridAverage',0.1); gridStep = 0.5; relPose = pcregisterndt(ptCloud2Downsampled,ptCloud1,gridStep);

Add a connection between the two views.

vSet = addConnection(vSet,1,2,relPose);

Compute the accumulated absolute pose.

absPose2 = rigid3d(absPose1.T*relPose.T );

Update the absolute pose of second view.

vSet = updateView(vSet,2,absPose2);

Get absolute poses.

sensorPoses = poses(vSet)
sensorPoses=2×2 tableViewId AbsolutePose ______ ____________ 1 1x1 rigid3d 2 1x1 rigid3d

Input Arguments
