Add fullpath to the local vehicle data folder.

dataDir = fullfile(toolboxdir('vision'), 'visiondata');
trainingData.imageFilename = fullfile(dataDir,...
                                       trainingData.imageFilename);
blds = boxLabelDatastore(trainingData(:,2:end));

Read a couple of times, before looking at the progress.

read(blds);
read(blds);

See the progress made by the boxLabelDatastore.
