Why do I get an error when I read the color information in the pointCloud struct?

ptColorCloud = pointCloud(all_Cloud, 'Color', uint8(all_labels));

gridStep = 0.05;

ptColorCloud = pcdownsample(ptColorCloud,'gridAverage',gridStep);

ptColorCloudOut = removeInvalidPoints(ptColorCloud);

ptOut = ptColorCloudOut.Location;

colorOut = ptCloudOut.Color;

When I get to the last line of code, I get to the point where I get to the end of the line, I get to say "This type of variable doesn't support indexing with points"

Hi,

The error seems to be occuring because 'ptCloudOut' is not defined in the code, but is trying to access 'ptCloudOut.Color'. You can use 'ptColorCloudOut.Color' instead, which seems to be the correct variable name containing the point cloud data.

colorOut = ptColorCloudOut.Color;

Hope this helps!
