Photos of LEGO bricks

Description

Random photos of the following LEGO bricks: 2419, 2450, 3022, 3031, 4070, 30357, 41682, 44570, 47998, 52107, 54383, 54384, 64799, 87609, 93274, 99206, 99781. The bricks were placed on a white sheet of paper, the photos were taken by hand, using Huawei P20 PRO camera positioned above the bricks. The photos were taken with and without flashlight. The bricks are randomly aligned, with the position and rotation possible for the given bricks (e.g. they are always lying on the physically possible side).

The photos were created as a test set for a neural network capable of distinguishing LEGO bricks.

Naming convention:

DIRECTORY/Brick_number/[01.jpg, 02.jpg…]

Where Directory can be one of the following:

  • 'with flashlight multiple per picture' – original photos of the bricks taken with the flashlight,
  • 'with flashlight cut' – cut out bricks from the aforementioned original photos,
  • 'without flashlight multiple per picture' – original photos of the bricks taken without the flashlight
  • 'without flashlight cut' – cut out bricks from the aforementioned original photos;

and Brick_number is the official LEGO ID number of the brick.
