Behind the unsealing of Shanghai, this group of developers "cloud gathering" built an AI anti epidemic robot

This year, 4 On the day , Wujingjing, a third year graduate student at Beijing University of Posts and telecommunications, accidentally saw his friend zhaozeming brushing the screen in the developer community —— original , The other party is developing a service for Shanghai Jiayi Shuian community AI Anti epidemic robot , Share your plans with interest 、 Soliciting companions .

In limine , Wujingjing did not pay attention to this . However, as the epidemic situation in Shanghai is more and more affecting our hearts , Plus the continued Amway of friends , After they had a good chat , Wujingjing also officially joined AI Research and development of anti epidemic robot .

At the time , As a propeller developer and technical expert （PPDE） Wujingjing may not have thought , in PPDE In the community “ This culminated ”, It's even linked up with developers from all over the country , use AI Lighten the burden for the hardworking neighborhood committees and community volunteers 、 Increase of efficiency , Contribute to Shanghai's fight against epidemic diseases .

A material distribution system

Turn into an anti epidemic robot

The coming of the epidemic , This has greatly challenged the management and operation of many residential areas in Shanghai .4 At the beginning of , Also graduated from Shanghai Jiaotong University 、 Wuguangzheng and lisiying, who live in Shanghai Jiayi Shuian community, both signed up for community volunteers . In the volunteer community , The issue of community governance has triggered a heated discussion , The volunteers even sorted out a dozen proposals for the neighborhood committee .

One of the suggestions aroused the interest of wuguangzheng and lisiying ： Whether we can develop a set of express delivery system , Make the distribution of materials in the community more efficient ？

“ It's better to develop it directly and let the neighborhood committee use it ？” The two of them hit it off with Ling Sikai, who is also a volunteer in the community , After two nights, I built a set of material allocation system to liberate manpower , It can not only help the neighborhood committee to automatically process the group purchase information of materials , You can also quickly create customized forms , It will soon be used in the community , The harvest is full of praise . Even the Secretary of the neighborhood committee of the community praised “ So that the neighborhood committee has made a qualitative leap in the work of ensuring people's livelihood ”.

The volunteers are delivering the materials with the distribution form processed by the system

When I first started to develop this system , The three volunteers considered putting the system on the wechat robot , But because everyone has no relevant experience , And hope to set up the system as soon as possible for the neighborhood committee to use , So the development plan of wechat robot was put aside for the time being . After the system goes online smoothly , Lisiying contacted open source friends and asked them to recommend , This led wujingjing and zhaozeming to join .

External help

Oar developers respond to every call

After the newcomers join ,AI The anti epidemic robot team operates in an orderly manner ： Someone is responsible for docking with the neighborhood committee , Someone iteratively optimizes the material allocation system , Some people are devoting themselves to the development of robots .

be based on Python Wechaty, Wujingjing and zhaozeming soon created AntigenBot Wechat robot , It is not only connected to the previous material distribution system , The module of multi-function message forwarding is also added —— The neighborhood administrator only needs to send text to the robot 、 picture 、 Small programs and other message contents , These messages will be automatically forwarded to the designated residential buildings within a certain period of time , Timely and conveniently synchronize various anti epidemic information for residents .

After rich functions AI The anti epidemic robot has been put into use in Jiayi Shuian community , Stable and smooth operation , It has greatly reduced the burden on the residents' committee staff and volunteers ; The team also put the plan in Github Open source on , At that time, I received many programmers' attention and feedback .

A programmer also from Shanghai contacted the project development team , Try to ask if you can add the function of antigen picture recognition and analysis to the anti epidemic robot .“ People should have antigen tests at home , It takes time and effort for the community to review the pictures of test results every day , If it can automatically identify and analyze 、 Just report the results .”

Wujingjing immediately thought , Is it possible to use the propeller character recognition Kit PaddleOCR And the propeller target detection kit PaddleDetection Development ？ Focusing on the field of naturallanguageprocessing, he decided to turn to the propeller developers who focus on the field of vision . Under the communication of the flying oar operation students , Wujingjing recruited from the technical experts group of propeller developers , Explain the project background and demands .

Slide up and down

After wujingjing issued the call, it triggered discussion among the propeller developers

What he didn't expect was , Dozens of propeller developers immediately responded , We have set up a special discussion and development group , At the beginning, you gave me advice every word . Final , Liujianjian from Gansu 、 Hanpengyuan from Chengdu and Mach from Beijing are the main players , Together with wujingjing, we worked on the development of antigen picture recognition function .

The recognition effect of antigen picture is amazing

“ The time when the group started recruiting coincided with the May 4th Youth Day , Everyone is full of blood . Although scattered throughout the motherland , But we young developers have the responsibility and obligation to contribute to the fight against the epidemic .” With the same belief , The three newly added propeller developers started from the data set , Problems follow ： The data set is not rich enough 、 Data desensitization is complex .

Everyone on the team is active , Ask volunteers in the community to help collect and provide 、 Do it yourself , The data set is getting fuller , The urgent need has been solved . In the face of multi-dimensional data desensitization ,PaddleOCR The ready-made models in help a lot .“ Out of the box , Second speed , Let me avoid a lot of detours .” Liu Jianjian sighed .

Hanpengyuan and Mach began to tackle how to make antigen detection image recognition more accurate . In order to iterate quickly and avoid the interference of time and other factors as much as possible , Two people walk along “ Walk on two legs ” The idea of realizing multi algorithm parallel . In addition to the target detection algorithm , They also try to improve the recognition accuracy by image retrieval , In order to cope with the possibility of uploading pictures .

Antigen picture recognition effect

at present , The function of antigen picture detection is also in AI The anti epidemic robot was successfully launched , It can not only remind users of antigen detection on time , It can also analyze user retransmissions 、 Missing antigen pictures , After sorting out the data, it will be automatically uploaded to the specified platform ; After testing , Recognition accuracy has achieved excellent results .

AI The anti epidemic robot has launched the antigen image recognition function

not long ago ,AI Anti epidemic robot walks out of Jiayi Shuian community , It has also been successfully deployed and used in Qingshuiyuan and other communities in Shanghai .“ From a community project to a link WeChaty、 Several major technical communities such as the flying oars , It was a wonderful process .” Lisiying said .

Looking back at the achievements of our concerted efforts in the past two months , Everyone feels thousands of things .“ The technique of flying oars is really easy to use , How to make it useful 、 Give Way AI The anti epidemic robot is more perfect and valuable , This is the direction of our continuous efforts .” Mach is Github There is also a sentence written on the homepage of the antigen detection project ： But make the oars AI stay , Don't teach the virus to destroy the country ！

6 month 1 Japan , Shanghai has been officially unsealed , The city is regaining its former vitality . This group is in different places 、 Young people from different backgrounds also have a common dream ： Give Way AI The project of anti epidemic robot continues , Let technology be implemented to truly change the lives of more people .
