removeInvalidPoints

Remove invalid points from point cloud

collapse all in page

Syntax

[ptCloudOut,indices] = removeInvalidPoints(ptCloud)

Description

[ptCloudOut,indices] = removeInvalidPoints(ptCloud) removes points with Inf or NaN coordinate values from point cloud and returns the indices of valid points.

Note

The output is always an unorganized (X-by-3) point cloud. If the input ptCloud is an organized point cloud (M-by-N-by-3), the function returns the output as an unorganized point cloud.

Create a point cloud object with NaN and Inf values.

xyzpoints = abs(randn(10,3)).*100;
xyzpoints(1:2:4,:) = nan('single');
xyzpoints(6:2:10,:) = inf('single');
ptCloud = pointCloud(xyzpoints);

Inspect the Location property of point cloud data to verify the occurrence of NaN and Inf values.

ptCloud.Location
ans = 10×3

Remove points with NaN and Inf values from the point cloud.

ptCloudOut = removeInvalidPoints(ptCloud);

Inspect the Location property of point cloud data to verify that the invalid points are removed.

ptCloudOut.Location

Input Arguments

collapse all

Point cloud, specified as a pointCloud object.

Output Arguments

collapse all

Point cloud, returned as a pointCloud object with Inf or NaN coordinates removed.

Note

The output is always an unorganized (X-by-3) point cloud. If the input ptCloud is an organized point cloud (M-by-N-by-3), the function returns the output as an unorganized point cloud.

Indices of valid points in the point cloud, specified as a vector.
