RecognizeTableAccurateOCR

Last updated: 2023-07-10 16:34:55

    1. API Description

    Domain name for API request: ocr.tencentcloudapi.com.

    This API is used to recognize regular tables, borderless tables, or multi-tables in images or PDF files containing Chinese and English texts. It returns the text content of each cell, supports recognition of rotated table images, and can save the recognition results into an Excel document. It delivers higher recognition accuracy than that of table OCR v2 and applies to more scenarios. The recognition accuracy in difficult table scenarios, such as irregular tables and nested tables (borderless tables contained in bordered tables), is better than that of table OCR v2.

    A maximum of 2 requests can be initiated per second for this API.

    We recommend you to use API Explorer
    Try it
    API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.
