LEGO bricks for training classification network

The data set contains images of 447 different classes of LEGO bricks used for training LEGO bricks classification network. The dataset contains two types of images: photos (10%) and renders (90%) aggregated into respective directories. Each directory (photos and renders) contains 447 directories labeled as the official brick type number. The images contains only bricks on white background, the renders were augmented randomly so that they resemble the real pictures.
Sample images are presented below. Real photos are on the left side and renders on the right side.

本数据集包含447类不同乐高积木（LEGO bricks）的图像，用于训练乐高积木分类网络。数据集包含两类图像：照片（占比10%）与渲染图（占比90%），两类图像分别存储于对应的目录中。每个主目录（照片目录与渲染图目录）下均包含447个以官方积木型号编号命名的子目录。所有图像均为纯白背景下的积木图像，渲染图经过随机数据增强处理，以更贴近实拍照片的视觉效果。示例图像如下：左侧为实拍照片，右侧为渲染图。
