Tencent Cloud Optical Character Recognition (OCR), based on the deep learning and multimodal large model technology of Tencent YouTu Lab, intelligently identifies text content in images as editable text or extracts structured information. OCR supports the recognition of identity documents, bank cards, invoices, and other standard cards and invoices. It also supports the recognition of various complex-format industry documents such as transportation and logistics weighbridge tickets and consignment notes, as well as healthcare documents such as diagnostic reports and expense lists.
This chapter describes the text recognition API interfaces, all of which are API 3.0 interfaces.
You can call APIs to perform operations on text recognition, such as general OCR, card OCR, invoice recognition, and document intelligence.
For information on all APIs supported by text recognition, please see API overview.
Common terminology for text recognition API interfaces: see the table below.
| Term | Description |
|---|---|
| JSON | is a lightweight data interchange format. Any type supported by the JavaScript language can be represented through JSON, such as strings, numbers, objects, and arrays. |
| SDK | is a collection of development tools used by software engineers to create applications for a specific software package, software framework, hardware platform, operating system, etc. |
For API parameter limits, refer to the parameter descriptions in each API document.
You can use the API Explorer tool to call APIs online.
This document uses the general printed text recognition (high-precision version) as an example. The steps to call the API through the API Explorer Tool are as follows:
