+# Introduction
+
+OCR (Optical Character Recognition) is a technology that enables the detection and recognition of text within images, scanned documents, and real-world scenes. It transforms visual text into editable and searchable digital text, supporting various applications such as document digitization, license plate recognition, and scene text detection.
+
+In this project, we use Baidu's PGNet model and deploy it on Seeed Studio's AI Box to achieve real-time OCR functionality.
