Photos and rendered images of LEGO bricks

The paper describes a collection of datasets containing both LEGO brick renders and real photos. The datasets contain around 155,000 photos and nearly 1,500,000 renders. The renders aim to simulate real-life photos of LEGO bricks allowing faster creation of extensive datasets. The datasets are publicly available via the Gdansk University of Technology “Most Wiedzy” institutional repository. The source files of all tools used during the creation of the dataset were made publicly available via GitHub repositories. The images, both photos and the renders were annotated with the unique brick ID and category from the official LEGO catalog. The proposed datasets are stored in easy-to-read formats and are labeled via directory structure allowing easy manipulation and conversion of metadata to other formats.
