PRI OCR 해석

In this tutorial we will learn how details are identified from images by reading the characters present on it. This is called Optical Character Recognition (OCR).

이 튜토리얼에서, we will learn 얼마나 details가 identified되는지 from 이미지들로부터

by 읽음으로써 the 글자들을 나타나는 on it.

This opens door for many applications like to automatically read the information from a business card, recognize a shop from its name board or recognize sign boards on road and much more.

Some of us might have already experienced these features through Google Lens, 

so today we will build something similar using an Optical Character Recognition (OCR) Tool from Google Tesseract-OCR Engine along with python and OpenCV to identity characters from pictures with a Raspberry Pi.

Pre-requisites

As told earlier we will be using the OpenCV Library to detect and recognize faces. So make sure to install OpenCV Library on Raspberry Pi before proceeding with this tutorial.

일찍이 말했듯이 우린 will be using the OpenCV Library

so make sure to install OpenCV Library on it

before proceeding진행하기전에 with this tutorial.

This tutorial will not explain how exactly OpenCV works, if you are interested in learning Image processing then check out this OpenCV basics and advanced Image processing tutorials.

Installing Tesseract on Raspberry Pi

To perform Optical Character Recognition on Raspberry Pi, we have to install the Tesseract OCR engine on Pi. To do this we have to first configure the Debian Package (dpkg) which will help us to install the Tesseract OCR. 

Use the below command on the terminal window to configure Debian Package.

To do this, we have to first 구성해야한다. the Debian Package를 (=dpkg)

which will help us to install the Tesseract OCR.

Then we can proceed with installing the Tesseract OCR (Optical Character Recognition) using the apt-get option. The command for the same is given below.

Your terminal window will look something like below, it will take around 5-10 minutes for the installation to complete.

Simple Character Recognition Program on Pi

Since we have already installed the Tesseract OCR and Pytesseract packages in our PI. 

We can quickly write a small program to check how the character recognition is working with a test image. 

The test image I used, the program and the result can be found in the below image.
