Lub koob yees duab ntau lub ntsej muag tuaj yeem yog cov cuab yeej siv los tshuaj xyuas kev ntxhov siab hauv cov nroj tsuag, lossis paub txog hom tsiaj sib txawv ntawm qhov sib txawv ntawm qhov kos npe kos npe ntawm cov nroj tsuag feem ntau. Yog ua ke nrog lub drone, lub koob yees duab tuaj yeem muab cov ntaub ntawv kom nrawm NDVIs (Qhov Sib Txawv Sib Txawv Sib Txawv Zaub Tsiaj), tsim mosaics ntawm kev ua liaj ua teb, hav zoov lossis hav zoov, nkag siab nitrogen siv, tsim cov duab qhia chaw thiab lwm yam. Tab sis cov koob yees duab ntau lub ntsej muag tuaj yeem kim, thiab lawv cov nqi ncaj qha sib piv rau cov thev naus laus zis uas lawv siv. Ib txoj hauv kev ib txwm siv rau spectrometry yog siv ntau lub koob yees duab nrog cov lim ntev lossis luv bandpass uas tso cai rau qhov xav tau kom dhau lub nqaj thaum thaiv lwm tus. Muaj ob txoj kev sib tw rau txoj kev ntawd; ua ntej, koj yuav tsum tau ua lub koob yees duab tib lub sijhawm, lossis ze li sai tau; thiab thib ob, koj yuav tsum rau npe (sib koom ua ke cov duab txheej tom qab txheej) cov duab kom lawv tuaj yeem tsim ib qho kev sib xyaw zaum kawg nrog cov kev xav tau hauv nws. Qhov no txhais tau tias kev ua tiav loj tom qab yuav tsum tau ua, siv sijhawm thiab peev txheej (siv software kim xws li arcmap, tab sis tsis tas yuav tsum). Lwm txoj hauv kev tau hais txog qhov no hauv ntau txoj kev; kev tsim kho thev naus laus zis tsis ntev los no ntawm qib ua haujlwm tau tso cai tsim cov scan CMOS sensors nrog cov ntxaij lim dej sib xyaw ua ke hauv lub sensor teeb tsa. Lwm txoj hauv kev yog siv lub nqaj splitter (prism) uas yuav coj ncaj teeb sib txawv ntawm lub teeb mus rau qhov sib txawv sensor. Tag nrho cov thev naus laus zis no tsis kim heev thiab yog li tsis ncav cuag cov kws tshawb fawb thiab tsim khoom. Raspberry pi laij cov lej thiab nws pawg thawj coj txhim kho muab cov lus teb pheej yig rau ob peb ntawm cov lus nug no (tsis yog txhua qhov).

Kauj Ruam 1: Pab kom Cov Koob Yees Duab

Nco ntsoov tias koj ua raws cov kauj ruam rau teeb tsa lub koob yees duab hauv CM raws li qhia hauv cov lus qhia hauv qab no:

www.raspberrypi.org/documentation/hardware…

Ua ob lub koob yees duab tib lub sijhawm siv:

sudo raspistill -cs 0 -o test1-j.webp

Siv cov ncauj lus hauv qab no yog tias yog vim li cas nws tsis ua haujlwm:

www.raspberrypi.org/forums/viewtopic.php?f…

Cov lus qhia ntxiv yog tias koj tab tom pib kos nrog CM ntawm no:

www.raspberrypi.org/documentation/hardware…

Kauj ruam 2: Wireless Serial Communication

Yuav ib txheej xov tooj cua telemetry zoo li cov no:

hobbyking.co.uk/hobbyking/store/_55559_HK…

Cov xov tooj cua no muaj plaub lub xov hlau: Hauv av (dub), TX, RX, VCC (liab). Peal tawm ib qho ntawm cov xov hluav taws xob thiab siv cov poj niam txuas uas haum rau GPIO koob. Txuas tus txuas txuas dub rau hauv av, liab rau 5V, TX rau tus pin 15, thiab RX rau tus pin 14 ntawm J5 GPIO lub taub hau ntawm lub laij lej txhim kho pawg thawj coj saib.

Nco ntsoov tias koj teev tus nqi baud rau 57600, thiab tias koj lub khoos phis tawj lub computer tau lees paub thiab ntxiv xov tooj cua li COM (hauv Windows siv tus thawj tswj ntaus ntawv rau qhov ntawd). Yog tias siv Putty, xaiv cov lej, qhov chaw nres nkoj COM (3, 4 lossis xijpeem nws nyob hauv koj lub khoos phis tawj), thiab teeb tsa tus lej baud rau 57600. Hloov koj li CM rau thiab tom qab nws ua tiav kev thauj khoom, nyem nkag rau hauv koj lub computer yog tias koj tsis t pom ib qho ntawv los ntawm kev txuas. Yog tias koj pom cov ntawv tsis txaus ntseeg, mus thiab tshawb xyuas /boot/cmdline.txt. Tus nqi baud yuav tsum yog 57600. yog tias muaj teeb meem ntxiv tshwm sim, thov txheeb xyuas cov lus qhia hauv qab no:

Kauj Ruam 3: Cov Koob Yees Duab…

Koj tuaj yeem siv lub koob yees duab tiag tiag hauv lawv qhov kev teeb tsa qub, tab sis yog tsis yog, koj yuav tsum hloov kho lawv kom haum rau M12 lo ntsiab muag. Nco ntsoov tias lub koob yees duab raspberry pi V1 thiab V2 txawv me ntsis, yog li, cov tuav M12 qub yuav tsis ua haujlwm ntawm lub koob yees duab tshiab. Tsis tas li, muaj qee qhov teeb meem thaum ua rau lub koob yees duab tshiab zoo ib yam, yog tias koj tau ntsib ib qho ntawm cov teeb meem no thov txheeb xyuas cov ncauj lus no hauv raspberry pi forum:

www.raspberrypi.org/forums/viewtopic.php?t…

Hauv txhua qhov xwm txheej, sudo rpi-hloov tshiab yuav tsum kho qhov teeb meem.

M12 tus tuav lub lens tuaj yeem "zom" nrog Dremel txhawm rau kom haum rau qhov txuas ntawm CMOS sensor nrog lub koob yees duab board. Ntsia lub lens qub, thiab tso lub lens tshiab hla tus tuav M12. Rau cov txiaj ntsig zoo dua koj tuaj yeem tshem tawm tag nrho ntawm tus thawj lub lens adapter, tab sis nws yuav tsis tsim nyog ua haujlwm nyob rau hauv qhov pom ntawm qhov kev pheej hmoo uas cuam tshuam rau kev puas tsuaj lub sensor. Kuv rhuav tshem tsawg kawg rau lub koob yees duab laug cam ua ntej tswj kom tshem tau cov yas yas uas zaum saum lub CMOS sensor.

Kauj Ruam 4: Kev Txuas Wifi thiab Cia Ntxiv

CM pawg tswj hwm kev txhim kho tsuas muaj ib qho chaw nres nkoj USB; raws li qhov tshwm sim uas koj yuav tsum tau siv nws kom ntse heev, piv txwv. kev twb kev txuas wifi. Yog tias koj xav mus ib puag ncig qhov ntawd, koj yuav tsum tau siv koj cov txuj ci sib txuas hlau thiab txuas ob lub USB txuas hauv qab ntawm pawg thawj coj loj, qhov chaw USB tau muab muag. Yog tias koj siv tib yam kuv muaj

www.amazon.co.uk/gp/product/B00B4GGW5Q/ref…

www.amazon.co.uk/gp/product/B005HKIDF2/ref…

Tsuas yog ua raws kab ntawv xaj hauv daim duab.

Thaum ua tiav, txuas koj lub wifi module rau lub chaw nres nkoj ob, ua haujlwm ntawm CM thiab saib yog tias wifi module ua haujlwm tau raug.

Nws yooj yim dua los txuas daim npav SD dua li USB tsav, yog li yuav qee yam zoo li no:

www.amazon.co.uk/gp/product/B00KX4TORI/ref…

Txhawm rau nce qhov chaw cia sab nraud tshiab, ua raws cov ntawv qhia no kom zoo:

www.htpcguides.com/properly-mount-usb-stora…

Tam sim no koj muaj 2 USB chaw nres nkoj, khaws cia ntxiv thiab txuas wifi.

Kauj Ruam 5: Luam Ntawv

Siv ABS

Kauj Ruam 6: Muab Cov Khoom Ua Ke

Ua ntej koj sib sau lub koob yees duab, txuas tus saib xyuas thiab keyboard rau CM, thiab tsom mus rau lo ntsiab muag. Txoj hauv kev zoo tshaj los ua qhov ntawd yog siv cov lus txib hauv qab no:

raspistill -cs 0 -t 0 -k -o my_pics%02d.jpg

Qhov ntawd khiav lub koob yees duab mus tas li, yog li saib xyuas koj lub vijtsam, kaw lub lens kom txog thaum tsom mus. Nco ntsoov ua qhov ntawd nrog lwm lub koob yees duab los ntawm kev hloov -cs hais kom ua los ntawm 0 txog 1.

Thaum koj cov tsom iav tsom mus rau tso me me ntawm cov kua nplaum nruab nrab ntawm lub lens thiab M12 lub lens tuav kom tiv thaiv kev txav ntawm lub lens. Ua tib yam thaum muab lo ntsiab muag rau rooj plaub. Ua kom ntseeg tau tias ob lub lo ntsiab muag sib haum kom ntau li ntau tau.

Siv lub laum qhib lub qhov nyob ntawm ib sab ntawm rooj plaub thiab muab los ntawm lub xov tooj cua kav hlau txais xov. Tso xov tooj cua kom ruaj ntseg los ntawm kev siv daim kab xev ob lub ntsej muag thiab txuas nws mus rau GPIO.

Muab CM pawg thawj coj txhim kho sab hauv rooj plaub thiab ruaj ntseg nws nrog 4 10mm hlau hexagonal txuas ntxiv. Ruaj ntseg lub koob yees duab txuas txuas kom lawv tsis txhob thaws sab hauv.

Kauj Ruam 7: teeb tsa Dropbox-Uploader, Nruab Lub Koob Yees Duab Tsab Ntawv

Nruab dropbox_uploader ua raws cov lus qhia hauv no

github.com/andreafabrizi/Dropbox-Uploader

Siv ib tsab ntawv zoo ib yam li hauv daim duab.

Kauj Ruam 8: Cov Khoom Kawg

Lub koob yees duab zaum kawg tuaj yeem tso rau hauv qab qhov loj me (650 mm ⌀) drone lossis txawm tias me dua. Nws txhua yam nyob ntawm kev teeb tsa. Lub koob yees duab tsis ntau tshaj 350-400 grams.

Txhawm rau lub hwj chim lub koob yees duab, koj yuav tsum muab lub roj teeb cais, lossis txuas lub koob yees duab mus rau lub hwj chim tswj hwm ntawm koj lub drone. Ceev faj tsis pub dhau lub zog xav tau ntawm CM pawg thawj coj. Koj tuaj yeem siv cov khoom hauv qab no los txhawb koj lub koob yees duab:

www.adafruit.com/products/353

www.amazon.co.uk/USB-Solar-Lithium-Polymer…

Koj tseem tuaj yeem tsim kev txhawb nqa, thiab tiv thaiv kev co dampers raws li koj cov lus qhia tshwj xeeb.

Thaum koj tau thaij thawj daim duab, siv GIS program xws li Qgis lossis Arcgis Map txhawm rau sau koj cov duab. Koj tseem tuaj yeem siv matlab.

Zoo siab davhlau!
