Description

Amazon Berkeley Objects is a collection of 147,702 product listings with multilingual metadata and 398,212 unique catalog images. 8,222 listings come with turntable photography (also referred as spin or 360º-View images), as sequences of 24 or 72 images, for a total of 586,584 images in 8,209 unique sequences. For 7,953 products, the collection also provides high-quality 3d models, as glTF 2.0 files.

The collection is made of the following files:

• README.md - The present file.

• LICENSE-CC-BY-NC-4.0.txt - The License file. You must read, agree and comply to the License before using the Amazon Berkeley Objects data.

• listings/metadata/listings_<i>.json.gz - Product description and metadata. Each of the 16 files is encoded with UTF-8 and gzip-compressed.

• images/metadata/images.csv.gz - Image metadata. This file is a gzip-compressed comma-separated value (CSV) file with the following columns: image_id, height, width, and path.

  • image_id (string): this id uniquely refers to a product image. This id can be used to retrieve the image data from Amazon's Content Delivery Network (CDN) using the template: https://m.media-amazon.com/image/I/<image_id>.<extension> [^1], where <extension> is composed of the characters following the dot in the path field. Any value occurring in the main_image and other_images attributes of product metadata is an image_id present in this file.
  • height (int) and width (int): respectively, the height and width of the original image.
  • path: the location of the image file relative to the images/original/ or images/small/ directories. A path is composed of lowercase hex characters (0-9a-f) that also uniquely identifies images. The first two characters are used to build a file hierarchy and reduce the number of images in a single directory. The extension is jpg except for few png files.

  Below are are first 10 lines of images/metadata/images.csv.gz:

• images/original/<path> - Original image data. This directory contains the original high-resolution version of the images. See images/metadata/images.csv.gz for details of image naming.

• images/small/<path> - Downscaled image data. This directory contains the version of the images, where they have been downscaled such that their largest axis (height or width) is a maximum of 256 pixels. See images/metadata/images.csv.gz for details of image naming.

• spins/metadata/spins.csv.gz - Spin / 360º-View image metadata. This file is a gzip-compressed comma-separated value (CSV) file with the following fields: spin_id, azimuth, image_id, height, width, and path.

  • spin_id: a unique identifier for the image sequence.
  • azimuth: an integer between 0 and 71, representing the index in the spin sequence and the azimuth of the camera (in steps of 5º).
  • image_id: this id uniquely refers to an image. This is can be used to retrieve the image data using the template: https://m.media-amazon.com/image/I/<image_id>.jpg [^1].
  • height and width: respectively, the height and width of the image.
  • path: the location of the image file relative to the spins/original/ directory. The extension is jpg for all the images. The path is build from the spin_id and azimuth using the template <spin_id>_<azimuth:02d>.jpg and the first two characters of spin_id are used to build a file hierarchy and reduce the number of files in a single directory.

• 3dmodels/original/<path> - 3d model files. The 3d models are provided in the glTF-2.0 format (GLB/binary representation). All models adhere to the following conventions:

  1. Positive Y direction is up.
  2. Positive Z direction is pointing to the natural front-side of the product, wherever applicable.
  3. Products that are designed to stand on a surface (i.e. a floor) are centered on the origin, but translated up (towards positive Y) such that they stand on the Y=0 plane.
  4. Products that are designed to hang from a surface (i.e. a ceiling) are centered on the origin, but translated down (towards negative Y) such that they hang from the Y=0 plane.
  5. Products that are designed to hang on a wall are centered on the origin, but translated forward (towards positive Z) such that their backside aligns with the Z=0 plane.
