FOLASAGA

E uiga i ArduCam
ArduCam o se faʻataʻitaʻiga faʻapolofesa ma le gaosiga o SPI, MIPI, DVP ma USB mea pueata talu mai le 2012. Matou te ofoina atu foʻi faʻapitoa turnkey mamanu ma gaosiga fofo auaunaga mo tagata faʻatau e mananao ia latou oloa ia tulaga ese.

E uiga i le Pivariety Camera
ArduCam Pivariety o se Raspberry Pi mea pueata fofo e ave le advantage o le fa'aogaina o ana meafaigaluega ISP galuega. O le fa'aogaina o masini pu'eata ArduCam Pivariety, e mafai e tagata fa'aoga ona maua le fa'atinoga lelei ma le tele o ituaiga mea pu'eata, filifiliga tioata. Mo se taimi umi, e fa'atapula'aina e tagata fa'aoga Raspberry Pi le fa'aogaina o le ta'avale pu'e pu'e pu'e fa'apogai ma fa'aogaina mea pu'eata (V1/V2/HQ).
O lea ua mafai ai e ArduCam ona tuʻuina atu le ISP lelei mo Pivariety camera modules ma le Auto Exposure, Auto White Balance, Auto Gain Control, Lens Shading Correction, ma isi. pea, ma o le auala e maua ai le mea pueata o le libcamera SDK(mo C++)/libcamera-still/libcamera-vid/Streamer.

SOFTWARE

1. Fa'apipi'i Aveta'avale

wget -O install_pivariety_pkgs.sh https://github.com/ ArduCam/Arducam-Pivariety-V4L2-Driver/releases/download/install_script/install_pivariety_pkgs.sh chimed +x install_pivariety_pkgs.sh ./install_pivariety_pkgs.sh -y - e toe fa'afou

FAAMANATU: O le fa'apipi'iina o aveta'avale kernel e na'o le fa'afou fou 5.10. Mo isi lomiga kernel, fa'amolemole alu ile matou Doc itulau: https://www.arducam.com/docs/cameras-for-raspberry-pi/pivariety/how-to-install-kernel-driver-for-pivarietycamera/#2-how-to-build-raspberry-pi-kernel-driverfor-arducam-pivariety-camera

E mafai foi ona e asiasi i lenei itulau doc e faʻasino ile fesoʻotaʻiga meafaigaluega: https://www.arducam.com/docs/cameras-for-raspberry-pi/pivariety/2mp-imx462pivariety-low-light-camera-module/

2. Su'e le Aveta'avale ma le Meapueata
A mae'a ona e fa'apipi'i masini ma fa'apipi'i aveta'avale, e mafai ona e su'eina pe iloa ma galue le meapueata.

View le Tulaga o Aveta'avale ma Meapueata

dmesg | grep ArduCam
O le a faʻaalia le arducam-pivariety pe a faʻapipiʻi lelei le avetaʻavale ma le firmware version pe a mafai ona iloa le mea pueata. O le faʻaaliga e tatau ona le manuia pe a le mafai ona iloa le mea pueata, atonu e te siakiina le fesoʻotaʻiga lipine, ona toe faʻafou lea o le Raspberry Pi.

View le Vitio Node

O le Pivariety camera modules o loʻo faʻataʻitaʻiina e pei o le masini vitio masani i lalo o / dev / video * node, o lea e mafai ai ona e faʻaogaina le ls poloaiga mo le lisiina o mea i totonu o le / dev folder.
ls /dev/vitio* –
l Talu ai o le mea pu'e pu'e ata e V4L2 fa'amalieina, e mafai ona e fa'aogaina le V4l2 fa'atonutonu e lisi ai le avanoa lanu lagolago, iugafono, ma fua fa'avaa. v4l2-ctl –list-formats-ext.

FAAMANATU: E ui ina lagolagoina le V4L2 interface, ae na o ata RAW format e mafai ona maua, e aunoa ma le lagolago a le ISP.

3. Fa'apipi'i Aloaia Libcamera App
./install_pivariety_pkgs.sh -p libcamera_dev
./install_pivariety_pkgs.sh -p libcamera_apps

4. Pu'e Ata ma Fa'amau Vitio

Pu'e ata

Mo example, muamuaview mo 5s ma sefe le ata e igoa test.jpg
libcamera-still -t 5000 -o test.jpg

Faamaumau le vitio

Mo example, pu'eina se vitio H.264 10s ma le fa'avaa tele 1920W × 1080H

libcamera-vid -t 10000 –lautele 1920 –maualuga 1080 -o suega.h264

FAAMANATU: H.264 faatulagaga na o le lagolagoina 1920x1080 ma lalo iugafono.

3. Ua le mafai ona fa'apipi'i le Aveta'avale
Fa'amolemole siaki le kernel version, matou te tu'uina atu na'o le aveta'avale mo le ata aupito lata mai o le kernel version image pe a fa'amatu'u le Pivariety camera.

Manatua: Afai e te manaʻo e tuʻufaʻatasia le avetaavale kernel na o oe, faʻamolemole vaʻai ile Doc itulau: https://www.arducam.com/docs/cameras-for-raspberry-pi/pivariety/how-to-installkernel-driver-for-pivariety-camera/

Afai e te mauaina le mea sese lava e tasi, e mafai ona e faia le filifiliga sese e uiga i le avetaavale ata. Fa'amolemole mulimuli i le itulau ArduCam Doc e filifili ai le aveta'avale ata sa'o.

5. Su'e i le meapueata moni (raspistill etc.)
Fa'asa'o le file o /boot/config.txt, fai dtoverlay=ArduCam sui i # dtoverlay=ArduCam A mae'a le suiga, e tatau ona e toe fa'afouina le Raspberry Pi. toe fa'afouina le soda

FAAFESOOTAI MATOU
Afai e te manaʻomia la matou fesoasoani pe manaʻo e faʻavasega isi faʻataʻitaʻiga o Pi kamera, lagona le saoloto e faʻafesoʻotaʻi matou.
