{"url":"/dataset/mobilebrick","name":"MobileBrick","full_name":null,"description_markdown":"Generate high-quality 3D ground-truth shapes for reconstruction evaluation is extremely challenging because even 3D scanners can only generate pseudo ground-truth shapes with artefacts. We propose a novel data capturing and 3D annotation pipeline to obtain precise 3D ground-truth shapes without relying on expensive 3D scanners. The key to creating the precise 3D ground-truth shapes is using LEGO models, which are made of LEGO bricks with known geometry. The MobileBrick dataset provides a unique opportunity for future research on high-quality 3D reconstruction thanks to two distinctive features: 1) A large number of RGBD sequences with precise 3D ground-truth annotations. 2) The RGBD images were captured using mobile devices so algorithms can be tested in a realistic setup for mobile AR applications.","description_withheld":null,"homepage":"https://code.active.vision/MobileBrick/","introduced_date":"2023-03-06","introduced_date_note":null,"introduced_by":{"paper":"/paper/mobilebrick-building-lego-for-3d","title":"MobileBrick: Building LEGO for 3D Reconstruction on Mobile Devices","first_author":"Kejie Li","url":null},"license":{"name":"CC BY-NC-ND","url":null},"modalities":[{"name":"3D","url":"/datasets/modality/3d"},{"name":"RGB-D","url":"/datasets/modality/rgb-d"}],"tasks":[{"name":"3D Reconstruction","url":"/task/3d-reconstruction","datasets_with_task":"/datasets/task/3d-reconstruction"}],"languages":[{"name":"English","url":"/datasets/language/english"}],"variants":["MobileBrick"],"data_loaders":[],"num_papers_in_archive":6,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[],"papers_with_a_benchmark_row":[],"syntology_totals":{"read_at":"2026-09-24T18:15:14+00:00","papers_with_samples":0,"samples_harvested":0,"samples_ran":0,"samples_unverified":0,"pointer_only_for_licence":0,"papers_with_no_sample_that_ran":0,"note":"the per-paper counts above, summed; not a rate"},"papers_note":"The archive never published its papers-using-dataset list; these are papers with a leaderboard row on this dataset's benchmarks."}
