Ụzọ 5 bara uru iji Raspberry Pi. Akụkụ nke abụọ

Hey Habr.

В akụkụ mbụ A tụlere ụzọ ise iji Raspberry Pi. Isiokwu a tụgharịrị bụrụ ihe na-atọ ụtọ nke ukwuu, taa, m ga-eleba anya n'ọtụtụ nhọrọ maka otu ị ga-esi jiri microcomputer a bara uru.

Dị ka akụkụ nke mbụ, m ga-eleba anya na ụzọ ndị ahụ na-adịghị achọ mmemme.
Maka ndị nwere mmasị, ihe na-aga n'ihu dị n'okpuru ịkpụ.

1. Igwefoto onyunyo

Enwere ike iji Raspberry Pi na ihe fọrọ nke nta ka ọ bụrụ igwefoto nchekwa niile.
Ihe ndị a nwere ike ịrụ ọrụ na Raspberry Pi:

• Igwefoto webụ USB (dịka Logitech C910)
• Igwefoto IP (Axis, wdg) na injector PoE (ike 48V na-enye igwefoto dị otú ahụ site na eriri netwọk, nke na-enye ohere ịkwaga n'èzí ụlọ)
• Igwefoto na-ejikọ ozugbo na njikọ dị na RPi (dị ka ọ dị na foto dị n'elu).

Enwere ọtụtụ nhọrọ maka ịhazi ngwanro ebe a. Ị nwere ike iji ngwugwu ahụ Motion, nke nwere ntọala na-agbanwe agbanwe. Ị nwere ike dee ozugbo site na njikwa site na iji ffmpeg, ma ọ bụ ị nwere ike jiri Python na OpenCV dee onye na-ahụ maka gị n'ikpeazụ. Ị nwere ike gbasaa iyi vidiyo, jiri nchọpụta ngagharị, zipu foto site na email, wdg.

Maka ọrụ ọ bụla na-akpa ike (nke gụnyere nhazi vidiyo) na Raspberry Pi, achọrọ ike ọkụ 2.5A dị elu nke na-achọsi ike na heatsink na CPU bụ ihe na-achọsi ike (ị nwere ike nweta ya ọnụ ala na China maka $ 1- 2 site na ịchọ raspberry pi heatsink). Ma ọ bụghị ya, ngwaọrụ nwere ike ifriizi, mperi faịlụ nwere ike ịpụta, wdg.

2. Audio ndekọ

Site na igwe okwu USB, enwere ike iji Raspberry Pi dị ka ahụhụ na ngwaọrụ ndekọ ọnụnụ nwere kọmpat. Ọzọkwa, enwere ọtụtụ nhọrọ maka ịhazi ngwanro ahụ - ị nwere ike ide faịlụ mpaghara na kaadị SD, ị nwere ike gbasaa na PC ọzọ, ma ọ bụ gbasaa na netwọkụ.

3. Prof. foto

Adịla mgbagwoju anya p3 na p1. Na paragraf nke mbụ, anyị na-ekwu maka igwefoto onyunyo vidiyo, mana Raspberry Pi nwekwara ike ijikwa igwefoto ndị ọkachamara sitere na Canon, Nikon, Sony, wdg. Igwefoto dị nnọọ mkpa ijikọ na Raspberry Pi site na USB.

Ọba akwụkwọ ekwako2 и libgphoto2 nwere ma ikike ịrụ ọrụ site na ahịrị iwu na interfaces maka Python na C++, nke na-enye gị ohere iji Raspberry Pi jikwaa "DSLR", dịka ọmụmaatụ, maka ịse foto oge. Ndepụta igwefoto akwadoro O buru ibu ma kpuchie ihe fọrọ nke nta ka ọ bụrụ ụdị niile, site na nke oge a ruo ndị ochie site na 10 afọ gara aga.
