OCR based Passport Recognition Camera

In our previous blog “Develop an open-source Raspberry Pi OCR solution using Edge AI camera” we introduced using OpenNCC to develop an OCR system. Today we are going to introduce using OpenNCC IP4 (based on Raspberry Pi 4B ) to develop an OCR Passport Recognition application. In this blog, we will mainly focus on the whole development process, and leave detailed development instructions in future blogs.
