How to use PHP and Alibaba Cloud OCR to recognize handwritten text?

Introduction:
With the development of technology, handwritten text recognition has gradually become one of the important applications of artificial intelligence. Alibaba Cloud OCR (Optical Character Recognition) is a powerful text recognition service that can recognize handwritten text in pictures with high accuracy. This article will introduce how to use PHP combined with Alibaba Cloud OCR to realize handwritten text recognition.

Preparation work:

  1. Register an Alibaba Cloud account and activate the OCR service.
  2. Get AccessKey and AccessSecret.

Step One: Install PHP SDK

Please make sure that PHP has been installed and the correct operating environment has been configured.

Alibaba Cloud provides an official PHP SDK, which can be installed through Composer. Run the following command to install the SDK:

composer require aliyun/aliyun-ocr

After the installation is completed, we can use Alibaba Cloud OCR in PHP code Served.

Step 2: Create a recognition request

Before starting, we first need to save the handwritten text to be recognized as an image and upload it to Alibaba Cloud.

First, we need to introduce the SDK and initialize it:

require_once ('vendor/autoload.php');

use AlibabaCloudClientAlibabaCloud;
use AlibabaCloudClientExceptionClientException;
use AlibabaCloudClientExceptionServerException;
use AlibabaCloudCrCr;

AlibabaCloud::accessKeyClient('<YourAccessKeyId>', '<YourAccessSecret>')
    ->regionId('cn-hangzhou')
    ->asDefaultClient();

Then, we need to create an OCR request and specify the image URL to be recognized:

try {
    $result = Cr::v20180608()
        ->RecognizeCustomizedCharacter()
        ->withImageUrl('<YourImageUrl>')
        ->debug(true)
        ->request();
    print_r($result);
} catch (ClientException $e) {
    echo $e->getErrorMessage() . PHP_EOL;
} catch (ServerException $e) {
    echo $e->getErrorMessage() . PHP_EOL;
}

In the above code, We called the RecognizeCustomizedCharacter interface and specified the image URL to be recognized through the withImageUrl method. Finally, we made the request and printed the result. You can make appropriate modifications according to business needs.

Step 3: Process the recognition results

After the recognition is completed, a JSON containing the recognition results will be returned. The following is a typical result example:

{
    "Data": {
        "Result": "Hello, World!"
    },
    "RequestId": "A1234567-89BC-DEF0-1234-56789ABCDEF0"
}

We can extract the recognition result through the following code:

$ocrResult = $result->Data->Result;
echo '识别结果:' . $ocrResult;

The above code will output: Recognition result: Hello, World!

Conclusion:
Using PHP combined with Alibaba Cloud OCR, we can easily realize handwritten text recognition. Through the above steps, you can quickly build a handwritten text recognition system and adjust and optimize it according to your business needs.

I hope this article can help you, and I wish you good luck in using PHP and Alibaba Cloud OCR to recognize handwritten text!
