疫情攻坚战中的AI力量，腾讯云OCR助力智能化抗疫

人工智能技术正在成为阻断疫情传播、便捷老百姓日常生活的有效手段。就在社会各界齐心协力共同阻击疫情过程中，腾讯云AI团队基于领先的深度学习技术打造的文字识别OCR产品，正在成为国内众多地区进行无接触化社区防疫管控，师生远程在线教育的重要工具。

随着全国各地相继迎来复工大潮，日常居民出行频率较之前有了显著提升，抗击疫情的工作也进入攻坚期，而出入小区的必需凭证——出入证如何实现快速、安全的办理，也成了摆在所有物业和居民面前的难题。

如果采取传统的线下办理出入证方式，需要用户手动录入身份信息，不仅存在输入门槛高、效率低、易出错，同时还存在造假风险，另外，由于人群聚集，疫情期间还可能会导致交叉感染。

为了解决这样的难题，江苏鸿鹄电子科技有限公司通过使用腾讯云卡证类OCR产品，目前已经率先在南通市实现居民出入证“云办理”。居民只需在家通过手机上传各类有效证件，系统即可自动识别信息，轻松实现在线办理出入证。不仅大大提升了居民办证的体验，也助力南通全市的社区疫情防控工作效率得到提升。

由于方便快捷，产品自上线以来访问量节节攀升，并受到了社区居民的良好评价。目前，相关服务的日均访问量已超过30万，高峰时最高甚至一度达到60万。累计为用户节省近千万输入次数，缩短出入证办理时间。为了让更多市民尽快享受出入证云办理服务，腾讯云AI团队也紧急进行了系统的快速扩容支持，保证服务快速响应。

江苏鸿鹄相关负责人表示：“我们其实在疫情之前就和腾讯云方面有过多次的沟通，希望借助数字化技术来优化我们日常的办证效率。疫情发生后，我们第一时间上线了腾讯云的OCR技术，目前每天的办证效率提升了10倍，而且减少了人群的聚集，效率提升的同时，还有效阻断了疫情的传播。”

除了利用卡证OCR服务助力社区实现智慧防疫管控，在当前全国中小学生普遍“云上课”的场景下，腾讯云OCR产品也以其准确快速的文字识别技术解决了远程教育中师生互动不便等痛点。比如在实际教学过程中，作业的提交和批改成为很多学生和老师面临的一大难题，借助AI技术，这样的挑战已经成为历史。

作为一家业务覆盖全国多个城市，服务众多学员的职业培训机构，尚德教育利用腾讯云OCR产品实现了远程“拍照判分”。学生在纸上将老师布置的题目答案写好后拍照上传后，尚德教育APP会调用腾讯云OCR识别对文字部分进行自动判分。据老师们反馈，自从用了这个功能之后，课堂上师生之间的互动效率更高，教学质量也相应得到了提高。目前，尚德教育还在内部教职工信息管理系统中使用该技术，通过利用OCR自动读取识别证件等信息，大幅减少了员工的手动输入频次，有效提高了教职工各类信息的录入效率。

据了解，腾讯云OCR基于腾讯优图实验室世界领先的自研AI深度学习技术，可将各类图片、实物上的文字内容智能识别成为可编辑的文本，同时还具有识别准确性高、系统稳定性强、实用性高、易于开发调用等特点。

目前，腾讯云OCR产品的应用领域已经覆盖了通用文字识别、卡证文字识别、票据单据识别、汽车相关识别以及行业文档识别五大场景，不仅在腾讯内部的QQ、广点通等自有业务上得到了大量应用，还服务于金融、政务、物流、短视频、生活服务、即时通讯、汽车领域等众多外部用户。

以腾讯云卡证类OCR产品来说，它可以自动识别包括驾驶证等常用证件在内的各类信息字段，识别平均准确率达到95%以上。同时，支持头像抠图、PS/翻拍告警等增值能力，并且提供API、小程序、APP等多种接入方式。依托该服务，居民只需提交证件照片就可实现各类信息的在线提交和证件办理。

据腾讯云视觉产品负责人王磊介绍，接下来，腾讯云AI视觉产品还将不断升级迭代，基于自身在智能化领域的技术优势，推动腾讯云OCR产品在银行远程开户、票据自动化、医疗病例报告识别等方面持续发挥更大作用，为各行业抗击疫情提供更多支持。

Artificial intelligence technology is becoming an effective means to block the spread of epidemic and facilitate the daily life of the people. In the process of joint efforts of all walks of life to stop the epidemic, Tencent cloud AI team's OCR product for character recognition based on advanced deep learning technology is becoming an important tool for contactless community epidemic prevention control and remote online education for teachers and students in many areas in China.

With the tide of returning to work in succession across the country, the daily travel frequency of residents has been significantly improved compared with that before, and the work of fighting against the epidemic has also entered a critical period. How to achieve fast and safe handling of the access card, the necessary certificate for entering and leaving the community, has also become a problem for all properties and residents.

If the traditional offline access card processing method is adopted, the user needs to manually enter the identity information, which not only has high input threshold, low efficiency and error prone, but also has the risk of fraud. In addition, due to the crowd gathering, cross infection may also be caused during the epidemic.

In order to solve this problem, Jiangsu Honghu Electronic Technology Co., Ltd. has taken the lead in realizing "cloud handling" of resident pass in Nantong City by using Tencent cloud card OCR Products. Residents only need to upload all kinds of valid certificates through mobile phones at home, and the system can automatically identify information and easily handle online access cards. It not only greatly improved the experience of handling the certificate, but also helped to improve the efficiency of community epidemic prevention and control in Nantong.

Because of its convenience and rapidity, the product has been visited more and more since it was launched, and has been well appraised by the community residents. At present, the daily average visit volume of relevant services has exceeded 300000, and even reached 600000 at the peak. It can save users nearly ten million times of input and shorten the time of handling the pass. In order to enable more citizens to enjoy the access card cloud processing service as soon as possible, Tencent cloud AI team also urgently carried out the system's rapid capacity expansion support to ensure the rapid response of the service.

"We actually had many times of communication with Tencent cloud before the outbreak, and we hope to use digital technology to optimize our daily card handling efficiency," said the relevant person in charge of Jiangsu Honghu. After the outbreak, we launched Tencent cloud's OCR technology for the first time. At present, the efficiency of certificate handling every day has been increased by 10 times, and the crowd aggregation has been reduced. While the efficiency has been improved, the spread of the epidemic has also been effectively blockquoted. "

In addition to using card OCR service to help the community realize intelligent epidemic prevention and control, Tencent cloud OCR product also solves the pain points of inconvenient interaction between teachers and students in distance education with its accurate and fast character recognition technology under the current situation of "cloud class" for primary and secondary school students across the country. For exle, in the actual teaching process, the submission and correction of homework has become a big problem faced by many students and teachers. With the help of AI technology, such challenges have become history.

As a vocational training institution with business covering many cities and serving many students, Suntech education has realized remote "photo scoring" by using Tencent cloud OCR Products. After the students have written the answers to the questions assigned by the teachers on the paper, take photos and upload them, Suntech education app will call Tencent cloud OCR recognition to automatically score the text part. According to teachers' feedback, since the use of this function, the interaction between teachers and students in the classroom is more efficient, and the quality of teaching has been improved accordingly. At present, Suntech education also uses this technology in the internal staff information management system. By using OCR to automatically read identification documents and other information, it greatly reduces the frequency of staff's manual input, and effectively improves the efficiency of staff's input of all kinds of information.

It is understood that Tencent cloud OCR, based on the world's leading self-developed AI deep learning technology of Tencent excellent graphics laboratory, can intelligently recognize the text content of various pictures and objects into editable text, and also has the characteristics of high recognition accuracy, strong system stability, high practicability, easy to develop and call, etc.

At present, the application fields of Tencent cloud OCR products have covered the five scenarios of general character recognition, card and card character recognition, bill and document recognition, automobile related recognition and industry document recognition. It has not only been widely used in Tencent's internal QQ, guangdiantong and other self owned businesses, but also serves for finance, government affairs, logistics, short video, life services, instant messaging, and automobile leading Domain and many other external users.

For Tencent cloud card OCR Products, it can automatically identify all kinds of information fields including driver's license and other commonly used certificates, with an average recognition accuracy of more than 95%. At the same time, it supports value-added capabilities such as head matting, PS / remake alarm, and provides multiple access modes such as API, applet, app, etc. Relying on this service, residents can submit all kinds of information online and handle certificates only by submitting certificate photos.

According to Wang Lei, head of Tencent cloud vision products, next, Tencent cloud AI vision products will continue to upgrade and iterate. Based on its technical advantages in the field of intelligence, Tencent cloud OCR Products will continue to play a greater role in bank remote account opening, Bill automation, medical case report recognition and other aspects, providing more support for various industries to fight against the epidemic.
