RPC stands for Retail Product Checkout, which is a large-scale commodity dataset in the new retail automatic checkout scenario. Its total number of images (up to 83k) and the number of categories (up to 200) are both the largest in this field.

The 200 categories of goods in the RPC dataset belong to 17 major categories (such as instant noodles, paper towels, beverages, etc.), which naturally form a hierarchical structure.
