FPV yog qhov zoo nkauj heev. Thiab nws yuav zoo dua hauv 3d. Qhov thib peb qhov tsis ua rau muaj kev nkag siab ntau ntawm qhov deb, tab sis rau sab hauv Micro Quadcopter nws zoo meej.

Yog li kuv tau saib ntawm kev ua lag luam. Tab sis cov koob yees duab kuv pom tau hnyav heev rau lub micro quadcopter thiab koj xav tau tsom iav kim rau nws. Lwm qhov ua tau yog siv ob lub koob yees duab thiab ob lub tshuab xa xov. Tab sis dua koj muaj teeb meem ntawm cov iav tsom iav kim.

Yog li kuv txiav txim siab ua kuv tus kheej. Txhua lub koob yees duab ntawm kev ua lag luam siv FPGA txhawm rau ua daim duab 3d. Tab sis kuv xav khaws nws pheej yig thiab yooj yim. Kuv tsis paub meej tias nws yuav ua haujlwm tab sis kuv tau sim siv ob lub Sync Separator ICs, Tus tswj hwm Micro los tswj kev sib txuas thiab hloov pauv IC kom hloov ntawm lub koob yees duab. Qhov teeb meem loj tshaj plaws yog kom tau txais cov koob yees duab sib luag tab sis nws muaj peev xwm ua tau nrog tus tswj. Qhov tshwm sim zoo nkauj heev.

Lwm qhov teeb meem yog tsom iav 3d. Feem ntau koj xav tau tshwj xeeb tsom iav 3D uas kim kim. Kuv sim ob peb yam, tab sis kuv tsis tuaj yeem daws nws tsuas yog siv hluav taws xob. Yog li kuv txiav txim siab siv lub USB rub cov vis dis aus thiab raspberry Pi nrog google duab los qhia. Qhov no ua haujlwm zoo heev. Tab sis nws tsis zoo heev los muab lub vijtsam tso rau hauv cov duab los qhia thiab muaj txhua yam khoom siv hluav taws xob nyob ib puag ncig. Yog li kuv pib sau ib qho app hauv. Thaum kawg kuv tau ua tiav 3D FPV system rau hauv rau tsawg dua 70 Euro.

Muaj qhov ncua sijhawm txog 100ms. Qhov ntawd yog vim tus neeg nqa daim vis dis aus. Nws me me txaus los ya nrog nws.

Koj xav tau cov txuj ci zoo los ua lub koob yees duab vim tias muaj tus kheej ua lub rooj tsav xwm tab sis yog tias koj muaj kev paub me ntsis koj yuav tsum muaj peev xwm ua tau.

OK, cia pib nrog cov npe khoom.

Kauj Ruam 1: Daim Ntawv Teev Npe

3D Lub Koob Yees Duab:

• PCB: koj tuaj yeem tau txais PCB nrog cov khoom ntawm no (kwv yees li 20 Euro
• 2 Lub Koob Yees Duab: Nws yuav tsum ua haujlwm nrog yuav luag txhua lub koob yees duab FPV. Lawv yuav tsum muaj TVL tib yam thiab tib lub moos ceev. Qhov kev xaiv zoo yog siv qee lub cam uas koj tuaj yeem nkag tau yooj yim hauv Christal. Kuv siv ob lub koob yees duab me me nrog 170 degree lo ntsiab muag vim kuv xav siv nws ntawm Micro Quad. (kwv yees li 15 txog 20 Euro)
• FPV transmitter: Kuv siv qhov no (kwv yees li 8 Euro)
• Tus txais FPV (Kuv muaj ib qho pw ib ncig)
• 3d Luam Kab
• Easycap UTV007 tus tuav cov vis dis aus: Nws yog qhov tseem ceeb kom muaj UTV007 chipset. Koj tuaj yeem sim lwm UVC cov neeg nqa daim vis dis aus, tab sis tsis muaj qhov lees tias nws ua haujlwm (txog 15 Euro)
• USB OTG cable (li 5 Euro)
• 3d FPV Viewer Android App: Lite Version lossis puv version
• qee yam ntawm google cardboard. Tsuas yog google rau nws (kwv yees li 3 Euro)

Xav tau ntxiv:

• Soldering Hlau
• Soldering kev
• iav tsom iav
• AVR Programmer yog
• PC nrog avrdude lossis qee qhov AVR programming software
• Android xov tooj ntse nrog USB OTG txhawb nqa
• 3d tshuab luam ntawv rau lub koob yees duab tuav

Kauj Ruam 2: Sib dhos PCB

"chaw thau khoom =" tub nkeeg"

Xaus: Lub koob yees duab ua haujlwm zoo heev. Txawm hais tias nws tsis zoo tag nrho, Nws siv tau. Muaj qhov ncua sijhawm txog 100ms, tab sis rau kev ya ib txwm thiab sim 3d fpv nws zoo.

Cov Ntaub Ntawv thiab Cov Lus Qhia:

- Yog tias koj tsis muaj lub xov tooj hauv xov tooj uas txhawb nqa easycap UTV007 lossis UVC koj tuaj yeem tau txais ib qho yooj yim ntawm e-bay. Kuv yuav qub Motorola Moto G2 2014 rau 30 Euro.

- Lub koob yees duab tsis sib txuas txhua lub sijhawm. Yog tias koj tsis tau txais daim duab lossis daim duab tsis zoo sim rov pib dua lub koob yees duab ob peb zaug. Rau kuv uas ib txwm ua haujlwm tom qab ob peb zaug sim. Tej zaum qee tus neeg tuaj yeem txhim kho qhov chaws rau kev ua kom zoo dua qub.

- Yog tias koj tsis ua lub moos ntawm lub koob yees duab, ib daim duab yuav maj mam nce lossis nqis. Nws tsis muaj kev cuam tshuam tsawg yog tias koj tig lub koob yees duab los ntawm 90 degrees, daim duab yuav mus rau sab laug lossis sab xis. Koj tuaj yeem kho qhov kev sib hloov hauv app.

- Qee zaum sab laug thiab sab xis tau hloov pauv. Yog tias qhov tshwm sim rov pib dua lub koob yees duab. Yog tias qhov teeb meem tseem tseem sim teeb tsa DIFF_LONG parameter hauv 3dcam.h siab dua, rov sau cov cai thiab nyem cov ntaub ntawv hex dua.

- Koj tuaj yeem teeb tsa tus qauv rau PAL los ntawm kev tso PB0 thiab PB1 rau +5V

- Koj tuaj yeem teeb tsa tus qauv rau NTSC los ntawm kev tso PB0 rau +5V nkaus xwb

- Nrog PB0 thiab PB1 tsis txuas nrog qhov pib-pom hom ua haujlwm nrog qhov sib txawv loj (tus qauv)

- Tsuas yog PB1 txuas nrog +5V qhov pib-pom hom tau ua haujlwm nrog qhov sib txawv me me. Sim qhov no yog tias koj pom ib feem ntawm thawj daim duab nyob hauv qab ntawm daim duab thib ob. Txoj kev pheej hmoo rau hloov pauv cov duab yog siab dua.

- Kuv siv hom qauv nrog lub moos sib txuas PAL lub koob yees duab, tab sis kuv teeb lub app rau NTSC. Nrog qhov kev hloov kho no kuv muaj NTSC qhov tshwm sim thiab tsis muaj kev pheej hmoo ntawm kev hloov pauv cov duab.

- Kuv muaj xim tsis zoo cuam tshuam nrog lub moos tsis sib xws PAL lub koob yees duab. Nrog NTSC lub koob yees duab qhov no tsis tshwm sim. Txawm li cas los xij, ua kom lub moos zoo dua rau ob qho qauv.

Paub meej txog cov cai:

Cov cai tsuas yog sau tseg hauv 3dcam.h cov ntaub ntawv. Txhua qhov teeb meem tseem ceeb tuaj yeem ua tiav rau ntawd.

MIN_COUNT: Tom qab tus lej no ntawm kab sab tau hloov mus rau lub koob yees duab thib ob. Koj yuav tsum tso nws tseg li cas. MAX_COUNT_PAL: Qhov kev xaiv no tsuas yog siv hauv PAL hom. Tom qab tus lej ntawm kab no daim duab raug hloov rov qab mus rau thawj lub koob yees duab. Koj tuaj yeem ua si ib puag ncig nrog qhov ntsuas no yog tias koj siv PAL hom. MAX_COUNT_NTSC: Tib yam rau NTSCDIFF_LONG/DIFF_SHORT: Cov ntsuas no tau siv hauv hom pib pom. Tus lej no raug rho tawm los ntawm qhov pib pom lub sijhawm hloov pauv. Koj tuaj yeem ua si ib puag ncig nrog cov ntsuas no. MAX_OUTOFSYNC: Qhov no tau txhais los tshuaj xyuas kev sib txuas ntawm cov koob yees duab, tab sis nws yeej tsis ua haujlwm zoo. Tsuas yog tso nws zoo li nws lossis sim ua nws tus kheej.

Yog tias koj siv kuv li PCB koj yuav tsum tso cov seem uas txhais tau zoo li lawv. Tus makefile nyob hauv Debug nplaub tshev.

Qhov ntawd yog nws. Kuv yuav ntxiv cov vis dis aus dav dav thiab qhia rau quadcopter sai sai no. Txog tam sim no tsuas yog lub koob yees duab sim video.

Hloov kho 5. Lub Yim Hli 2018: Kuv tau tsim qhov program AVR tshiab rau lub koob yees duab sib txuas ua ke. Kuv tsis paub yog nws ua haujlwm thaum koj tsis sync lub moos. Yog tias koj muaj lub koob yees duab sib txuas koj yuav tsum siv nws.

Nws tuaj yeem tshwm sim uas muaj xim tsis zoo nrog PAL lub koob yees duab. Pib dua AVR kom txog thaum koj muaj daim duab zoo rau ob lub koob yees duab. Kuv ntxiv khawm rov pib dua rau kuv PCB rau qhov ntawd.

Nws tuaj yeem tshwm sim uas koj tau hloov pauv cov duab nrog NTSC lub koob yees duab. Pib dua AVR kom txog thaum nws nres kom hloov pauv. Koj tseem tuaj yeem ua si ib puag ncig nrog DIFF_SHORT qhov ntsuas hauv qhov chaws.

Muaj qee qhov kev hloov pauv rau qhov kawg version:

• PAL/NTSC tau txais kev kuaj pom tus kheej. Kev xaiv phau ntawv raug tshem tawm.
• Txhawm rau teeb DIFF_SHORT tso PB1 rau +5V. Koj yuav tsum ua qhov no yog tias koj pom ib feem ntawm daim duab thib ob hauv qab ntawm thawj daim duab.
• Cov koob yees duab yeej ib txwm ua tam sim no.

Nov yog qhov txuas

Hloov kho 22. Lub Ib Hlis 2019: Kuv muaj lub sijhawm los sim lub koob yees duab nrog kev hloov pauv 3D tsom iav. Nws ua haujlwm yam tsis ncua. (Kuaj nrog qub qub Virtual IO iGlasses thiab Headplay 3d tsom iav)
