這篇文章主要介紹了Python3使用騰訊云文字識(shí)別(騰訊OCR)提取圖片中的文字內(nèi)容方法詳解,需要的朋友可以參考下

百度OCR體驗(yàn)地址：

騰訊OCR體驗(yàn)地址：

https://cloud.tencent.com/act/event/ocrdemo

測(cè)試結(jié)果是：騰訊的效果要比百度的好

騰訊云目前額度是：

每個(gè)接口 1,000次/月免費(fèi)，有6個(gè)文字識(shí)別的接口，一共是6,000次/月

百度接口調(diào)用之前寫過(guò)文章

python實(shí)現(xiàn)百度OCR圖片識(shí)別過(guò)程解析

使用步驟

1、注冊(cè)賬號(hào)： https://cloud.tencent.com/

2、開(kāi)通服務(wù)：https://console.cloud.tencent.com/ocr/general

3、申請(qǐng)?jiān)L問(wèn)秘鑰：https://console.cloud.tencent.com/cam/capi

4、通過(guò) API 或 SDK 或命令行來(lái)使用服務(wù)

具體參考《操作指南》：https://cloud.tencent.com/document/product/866/17622

接口使用

1、安裝SDK

https://github.com/TencentCloud/tencentcloud-sdk-python

pip3 install tencentcloud-sdk-python

2、代碼實(shí)例
