Kauj Ruam 2: Kev Kawm Tshuab Nrog TensorFlow

TensorFlow yog lub tsev qiv ntawv pub dawb thiab qhib qhov software uas tuaj yeem siv rau kev kawm tshuab (ML) kev siv xws li kev sib txuas neural. TensorFlow tau tsim los ntawm Google Pab Pawg Lub Hlwb rau kev siv sab hauv hauv kev tshawb fawb thiab tsim khoom hauv Google.

Kev Kawm Tshuab sawv cev rau tus txheej txheem tshiab hauv kev ua haujlwm, qhov twg tsis yog siv cov txheej txheem qhia meej hauv cov lus xws li Java lossis C ++, koj tsim cov kab ke uas tau kawm txog cov ntaub ntawv txhawm rau txheeb xyuas cov cai nws tus kheej. Tab sis ML tiag tiag zoo li cas? Hauv cov vis dis aus series Tshuab Kawm Zero rau Hero, AI Tus Kws Tshaj Lij Laurence Moroney taug kev peb los ntawm qhov yooj yim Nyob Zoo Piv txwv ntawm kev tsim qauv ML txoj cai mus txog qhov piv txwv zoo ntawm lub zeem muag computer.

• ML Zero to Hero - Tshooj 1: Qhia rau Kev Kawm Tshuab
• ML Zero to Hero - Ntu 2: Lub Zeem Muag Hauv Computer Nrog ML
• ML Zero to Hero - Ntu 3: Qhia Txog Kev Sib Koom Tes Neural
• ML Zero to Hero - Ntu 4: Tsim Tus Qauv Duab

Cov ntaub ntawv keeb kwm yav dhau los (raws li nthuav tawm nrog HackerBox 0053): Cov kab lus no ntawm plaub qhov yeeb yaj kiab ntawm Neural Networks thiab Kev Kawm tob tau txais kev tshoov siab los ntawm phau ntawv online dawb, Neural Networks thiab Deep Learning. Lub vev xaib rau phau ntawv txuas rau tus lej repo rau cov piv txwv hauv cov yeeb yaj kiab.

Kauj Ruam 3: M5CAM Module

M5CAM Module yog lub rooj tsav xwm txhim kho rau kev ua cov duab thiab kev lees paub. Nws nta ESP32 system ntawm nti nrog 4M Flash thiab 520K RAM. Nws kuj tseem muaj 2 Megapixel OV2640 lub koob yees duab sensor teeb tsa. Tus qauv txhawb nqa cov duab xa tawm ntawm Wi-nkaus thiab nws tuaj yeem tsim kho thiab debugged ntawm qhov chaw nres nkoj USB-C.

M5CAM Module los ua ntej tso nrog qhov yooj yim Wi-nkaus webcam firmware duab. Ib qho yooj yim, txhawb lub rooj tsavxwm ntawm USB-C lossis GROVE. Hauv koj lub PC lossis lub xov tooj ntawm tes, txuas rau Wi-nkaus nkag mus siv lub SSID pib nrog m5stack. Thaum txuas nrog, qhib lub vev xaib thiab nthwv dej mus rau 192.168.4.1 qhov twg koj yuav tsum pom cov vis dis aus nkag los ntawm M5CAM.

Cov Ntaub Ntawv Online rau M5CAM

Kauj Ruam 4: TensorFlow Object Classification With M5CAM

Lob qhov Arduino TensorFlow Object Classifier sketch rau ESP32 lub koob yees duab laug cam.

Txhim kho ESP32 Cov Ntaub Ntawv Tso Cai Uploader rau hauv koj li Arduino IDE. ESP32 muaj Serial Peripheral Interface Flash File System (SPIFFS). SPIFFS yog lub teeb yuag cov ntaub ntawv tsim rau microcontrollers nrog lub flash nti, uas txuas nrog los ntawm SPI npav, zoo li ESP32 flash memory. Lub plugin no rau Arduino IDE txhawb nqa yooj yim upload cov ntaub ntawv rau hauv ESP32 filesystem.

Hauv Arduino IDE cov cuab yeej, xaiv:

• Pawg> ESP32 Dev Module
• Flash> 4MB
• Partition Scheme> Tsis muaj OTA (2MB APP/2MB SPIFFS)
• PSRAM> Enabled
• Chaw nres nkoj> {USB chaw nres nkoj cuam tshuam nrog M5CAM}

Ua qee qhov kev hloov pauv hauv daim ntawv cais cais los txhawb nqa M5CAM

Hauv ESP32CamClassificationTfjs.ino: Ntxiv koj li Wi-nkaus network 2.4GHz SSID thiab Password

Hauv camera_wrap.cpp: Nrhiav // Xaiv lub koob yees duab qauv

Hauv camera_pins.h: Mus rau tus pin txhais cov npe rau CAMERA_MODEL_M5STACK_PSRAMChange Y2_GPIO_NUM los ntawm 32 txog 17

Sau thiab xa mus rau M5CAM

Siv cov cuab yeej> ESP32 Sketch Data Upload txhawm rau upload cov ntaub ntawv rau SPIFF

Qhib Arduino IDE Serial Monitor

Ntaus lub khawm Pib dua ntawm M5CAM

Luam tus IP chaw nyob ntawm Serial Monitor

Siv qhov browser (ntawm sam 2.4GHz net) kom nthwv mus rau tus IP ntawd

Thaum tus qauv raug teeb tsa, rub tawm cov vis dis aus thiab kwv yees cov khoom. Raws li tau sau tseg rau qhov ua tau zoo tshaj plaws, kwv yees cov duab ntawm cov khoom zoo li piano, khob kas fes, fwj, thiab lwm yam.

Nyob ntawm seb M5CAM tuav lossis teeb tsa li cas, cov duab yuav hloov pauv. Yog tias yog, sim nrog tawm tswv yim tawm "yog txhais" rooj ncig: s-> set_vflip (s, 1); s-> set_hmirror (s, 1); hauv cov ntaub ntawv camera_wrap.cpp

Kauj Ruam 5: Sab nraum zoov & Ua txhaum daim npav Game

Sab nraum zoov & Kev ua txhaum cai yog qhov tshwm sim Cov Lus Teb Game los ntawm Black Hills Cov Ntaub Ntawv Ruaj Ntseg thiab Kev Tawm Tsam Zoo.

Sab nraum zoov & Kev ua txhaum cai muaj 52 daim npav tshwj xeeb los pab koj ua qhov teeb meem tshwm sim ntawm kev ua haujlwm tabletop thiab kawm tawm tsam kev tawm tsam, cov cuab yeej, thiab cov txheej txheem.

Koj yuav pom cov lus qhia yuav ua li cas ua si ntawm no. Txawm li cas los xij, peb paub koj yuav hack thiab kho lub lawj ntawm daim npav kom haum rau koj tus kheej xav tau rau koj thiab koj pab neeg lossis cov tub ntxhais kawm.

Kauj Ruam 6: AD8232 Electrocardiogram (ECG)

AD8232 (cov ntawv teev tseg) yog kev teeb tsa kev teeb tsa ua rau ECG thiab lwm yam kev ntsuas ntsuas biopotential. Nws yog tsim los rho tawm, ua kom nrov nrov, thiab lim cov cim me me biopotential thaum muaj cov xwm txheej tsis zoo, xws li cov uas tsim los ntawm cov lus tsa suab lossis cov chaw tso hluav taws xob nyob deb. Qhov kev tsim qauv no tso cai rau lub hwj chim ultralow analog-to-digital converter (ADC) lossis cov khoom siv microcontroller kos kom tau txais cov teeb liab tawm.

AD8232 cov qauv tuaj yeem yuav los ntawm Sparkfun. Lawv muaj phau ntawv qhia kev sib txuas zoo rau kev siv tus qauv nrog lub hauv paus Arduino board yog tias koj muaj ib qho muaj.

NCO TSEG: Cov cuab yeej no tsis yog siv los tshuaj xyuas lossis kho ib yam twg

Yog tias koj tsis muaj lub hauv paus Arduino board muaj, nws tuaj yeem siv AD8232 ECG nrog M5CAM module. Lawv tuaj yeem txuas nrog ntawm cov ntoo txuas (IO13 lossis IO4). Txij li cov ntoo txuas tau muab 5V thiab ECG cov qauv xav tau 3.3V, tus ntsuas hluav taws xob yuav tsum tau siv los tsim 3.3V los ntawm 5V kev tsheb nqaj hlau. LO- thiab LO+ pins tsis siv.
