OCR SDK Overview
SDK Introduction
Optical Character Recognition (OCR) detects and extracts text from images or scanned copies and converts the text into an editable format, freeing you from burdensome manual input while improving the efficiency of your business.
OCR provides services through open APIs. You can obtain inference results by accessing and calling APIs in real time, significantly improving the efficiency of your business.
OCR SDK encapsulates RESTful APIs provided by OCR to simplify development. You can directly call API functions provided by OCR SDKs to use OCR.
The developer guides for SDKs in various programming languages are as follows:
|
Programming Language |
Developer Guide |
|---|---|
|
Java |
|
|
Python |
|
|
Node.js |
|
|
PHP |
|
|
C++ |
|
|
Go |

|
NET |
Automatic Generation of Sample SDK Code
API Explorer allows for API search and platform debugging, with features such as quick and comprehensive search, visual debugging, access to help documentation, and online consultation.
You only need to modify API parameters in the API Explorer to automatically generate the corresponding sample code. In addition, you can build, debug, and run code in CloudIDE.
Mapping Between Services and APIs
Table 2 lists the mappings between OCR services and APIs.
