Daim duab 5: Yuav ua li cas peb coj tus neeg siv lub tswv yim thiab txiav txim siab yuav ua li cas thiaj li haum.

Kauj ruam 20: Livestream (camera_pi.py)

Peb tau siv tus yam ntxwv tshiab rau peb qhov chaw saib xyuas neeg rau zaub mov, muaj kwj nyob ntawm dab tsi tau tshwm sim hauv Server Room, qhov no tuaj yeem nkag mus rau txhua lub sijhawm, txhua qhov chaw. Yuav ua li cas cov dej nyob no ua haujlwm: Nws yog qhov tshwj xeeb uas tau ua hauv Flask, ua ke nrog Pi Lub Koob Yees Duab. Cov kab yeeb yaj kiab tau rub tawm raws li nws tau tshwm sim hauv lub neej tiag tiag, yog li koj tuaj yeem pom tseeb tias muaj qhov qeeb me ntsis (1-2 vib nas this) raws li cov kab ke video tau rub tawm thiab ua ke ua ke. Qhov no tsis tuaj yeem ua tiav yam tsis muaj xov, raws li cov keeb kwm yav dhau los nyeem ntas los ntawm lub koob yees duab thiab khaws cov thav duab tam sim no. Txiav tag nrho cov thav ntawv no ua ke yuav tso tawm cov kwj tawm.

Pic 2: Nov yog cov ntaub ntawv cais qhov twg tag nrho cov duab thav duab tau khaws cia thiab raws li koj tuaj yeem pom, peb tab tom siv picamera module txhawm rau nkag mus rau peb lub koob yees duab raspberry pi raws li qhov uas peb paub zoo tshaj plaws. Peb muaj chav kawm Lub Koob Yees Duab kom peb tuaj yeem ua lub luag haujlwm zoo li yog nws yog cov kwj tawm thiab tsis yog ntau cov duab sib dhos ua ke, yog li hauv daim ntawv thov tseem ceeb yuav coj nws mus ua kwj dej yam tsis tas yuav txhawj xeeb txog dab tsi tshwm sim tom qab.

Daim duab 3: Qhov no yog ib feem ntawm peb cov server.py cov ntaub ntawv qhov twg cov kwj dej nyob tau teev tseg. Cov chav kawm tseem ceeb uas peb tau xa tuaj rau qhov no yog Lub Koob Yees Duab los ntawm peb cov ntaub ntawv camera_pi.py nyob rau sab saum toj ntawm peb cov server.py cov ntaub ntawv. Peb tau piav qhia lub luag haujlwm ntawm peb cov npe hauv paus, gen, txawm li cas los xij nws tsuas yog siv rau thaum peb nkag mus rau /video_feed qhov twg peb cov kwj dej nyob ntawm, qhov twg nws yuav rov los ntawm txoj haujlwm no thiab xa rov qab cov kwj tawm ntawm lub vev xaib.
