How to use PHP and Alibaba Cloud OCR to implement business card recognition function?

With the continuous improvement of informatization, people often encounter scenarios in their daily lives where they need to identify the information on business cards. In order to improve efficiency and accuracy, we can use PHP and Alibaba Cloud OCR services to implement business card recognition functions. This article will introduce how to use PHP to call Alibaba Cloud OCR service and provide corresponding code examples.

1. Register an Alibaba Cloud account and activate the OCR service

First, we need to register an Alibaba Cloud account and activate the OCR service. The specific steps are as follows:

1.1 Visit the Alibaba Cloud official website: https://www.aliyun.com/

1.2 Click the "Register" button to register an account.

1.3 Log in to the Alibaba Cloud console.

1.4 Search "OCR" in the console and enter the OCR service page.

1.5 Click the "Activate Service" button and follow the page prompts to complete the activation of the OCR service.

2. Get the Access Key and Access Secret of Alibaba Cloud OCR

Before using the OCR service, we need to obtain the Access Key and Access Secret of Alibaba Cloud OCR. The specific steps are as follows:

2.1 Log in to the Alibaba Cloud console.

2.2 Search for "Access Key" in the console and enter the Access Key management page.

2.3 Click the "Create Access Key" button and follow the prompts to obtain the Access Key and Access Secret.

3. Install the aliyun-sdk dependency library of PHP

To call the Alibaba Cloud OCR service in PHP, we need to install the aliyun-sdk dependency library through composer. The specific steps are as follows:

3.1 Create a file named composer.json in the project root directory.

3.2 Add the following content to the composer.json file:

{
    "require": {
        "aliyuncs/oss-sdk-php": "^2.5"
    }
}

3.3 Switch to the project root directory in the terminal and use the following command to install the aliyun-sdk dependent library:

composer install

4. Write PHP code to implement the business card recognition function

After completing the previous preparations, we can start writing PHP code to implement the business card recognition function. The following is a simple sample code:

<?php

require 'vendor/autoload.php';

use AliyunApiOcrRequestV20191230RecognizeBusinessCardRequest;
use AliyunCoreDefaultAcsClient;
use AliyunCoreProfileDefaultProfile;

function recognizeBusinessCard($imagePath) {
    $accessKeyId = 'YourAccessKeyId'; // 替换成你自己的Access Key Id
    $accessSecret = 'YourAccessSecret'; // 替换成你自己的Access Secret
    $regionId = 'cn-shanghai'; // 替换成你自己的区域id

    $profile = DefaultProfile::getProfile($regionId, $accessKeyId, $accessSecret);
    $client = new DefaultAcsClient($profile);

    $request = new RecognizeBusinessCardRequest();
    $request->setImageURL("http://your-domain.com/your-image.jpg"); // 替换成你的图片URL，或者使用$imagePath作为本地图片路径

    $response = $client->getAcsResponse($request);

    return $response;
}

$imagePath = './business-card.jpg'; // 替换成你的名片图片路径
$result = recognizeBusinessCard($imagePath);

var_dump($result);

?>

In the code, we first introduced the dependency library of aliyun-sdk through the require statement, and then defined a recognizeBusinessCard function to implement the business card recognition function. Inside the function, we create a DefaultAcsClient object and call RecognizeBusinessCardRequest to initiate a business card recognition request. Finally, we print out the recognition results.

Pay attention to replacing the Access Key Id and Access Secret in the function with your own Alibaba Cloud credential information, and replace the URL or path of the image.

5. Run PHP code

After completing the code writing, we can run the PHP code through the command line. Execute the following command:

php your-php-file.php

Replace your-php-file.php with your PHP file name. After executing the code, we will be able to see the business card recognition results in the terminal.

Summary

By using PHP and Alibaba Cloud OCR service, we can easily implement the business card recognition function. We only need to register and activate the OCR service in Alibaba Cloud and call the OCR interface through PHP code to identify the information on the business card, which will facilitate our daily work.
