Brief Introduction
The current industrial landscape faces challenges in ensuring compliance with export language requirements. Existing solutions often fall short in accuracy and efficiency, leading to potential errors in product labeling and communication. This dataset aims to address the need for high-precision character detection in multilingual contexts, ensuring that products meet export language standards. The data collection involved capturing images from various industrial environments and labeling them with the corresponding text and language. Quality control measures included multiple rounds of annotation, consistency checks, and expert reviews to maintain high accuracy. The dataset is organized in JPG format, with structured metadata for easy access and analysis.
