ArduCam 2MP OG02B10 Pivariety Umbala weModyuli yeKhamera eShutter yeGlobal yeRaspberry Pi
INTSHAYELELO
Malunga neArducam
U-Arducam ubeyilo lobuchwephesha kunye nomenzi we-SPI, MIPI, DVP, kunye neekhamera ze-USB ukusukela ngo-2012. Sikwabonelela ngoyilo lwetkeykey eyenziwe ngokwezifiso kunye neenkonzo zezisombululo zabathengi abafuna ukuba iimveliso zabo zikhetheke.
Malunga nale Pivariety Camera
I-Arducam Pivariety sisisombululo sekhamera yeRaspberry Pi ukuthatha i-advantage yokusebenzisa imisebenzi yayo ye-ISP yehardware. Iimodyuli zekhamera yePivariety zenza abasebenzisi bafumane ukusebenza okungcono kunye neentlobo ezahlukeneyo zekhamera, iilensi zokukhetha. Ngamanye amazwi, i-Pivariety iqhekeza-ngokunciphisa imida yomthombo ovaliweyo oxhaswa ngokusemthethweni umqhubi wekhamera kunye neemodyuli zekhamera (V1 / V2 / HQ). Iimodyuli zekhamera ye-Pivariety zenze ukuba kube yi-ISP elungelelanisiweyo kunye ne-Auto Exposure, i-Auto White Balance, i-Auto Gain Control, i-Lens Shading Correction, njl. indlela yokufikelela kwikhamera yi-libcamera SDK (yeC ++)/libcamera still/libcamera-vid/Gstreamer. Le Pivariety OG02B10 Color Global Shutter Cam-era ifuduselwe Raspberry Pi Cameras, leyo kuphelisa izinto zakudala isivalo ukudubula ngesantya esiphezulu izinto ezihamba ngemibala imifanekiso ebukhali.

SOFTWARE
Ukufakwa komqhubi
wget -O install_pivariety_pkgs.sh https://github.com/ArduCAM/Arducam-Pivariety-V4L2-Driver/releases/download/install_script/install_pivariety_pkgs.sh
- chmod +x install_pivariety_pkgs.sh
- nstall_pivariety_pkgs.sh -p kernel_driver
cofa uy ukuze uqalise kwakhona
PHAWULA: Ufakelo lomqhubi wekernel luxhaswa kuphela yinguqulelo yamva nje ye-5.10. Ukufumana ezinye iinguqulelo zekernel, nceda uye kwiphepha lethu leDoc: https://www.arducam.com/docs/cameras-for-raspberry-pi/pivariety/how-to-install-kernel-driver-for-variety-camera/#2-how-to-build-raspberry-pi-kernel-driver-for-arducam-pivariety-camera
Ungandwendwela eli phepha ledoc ukubhekisa kuqhagamshelo lwehardware: https://www.arducam.com/docs/cameras-for-raspberry-pi/pivariety/pivariety-og02b10-2mp-color-global-shutter-camera-module/
Vavanya uMqhubi kunye neKhamera
Emva kokuba ugqibile indibano yehardware kunye nofakelo lomqhubi, unokuvavanya ukuba ikhamera ichongiwe kwaye iyasebenza.
View Ubume boMqhubi kunye neKhamera
Iza kubonisa i-arducam-pivariety ukuba umqhubi ufakwe ngempumelelo kunye nenguqulo ye-firmware ukuba ikhamera inokufunyanwa. Umboniso kufuneka ucutshungulwe ukuba ikhamera ayibonwa, kuya kufuneka ujonge uqhagamshelo lweribhoni, emva koko uqalise kwakhona iRaspberry Pi.
View iNode yevidiyo
Iimodyuli zekhamera yePivariety zilinganisiwe njengesixhobo sevidiyo esime-ard phantsi kwe/dev/video* node, ukuze ukwazi ukusebenzisa i-ls umyalelo wokudwelisa imixholo kwi/dev ifolda.
Ekubeni imodyuli yekhamera i-V4L2 iyahambelana, ungasebenzisa ulawulo lwe-V4l2 ukudwelisa indawo yombala exhaswayo, izisombululo, kunye neereyithi zesakhelo.
PHAWULA: Nangona i-interface ye-V4L2 ixhaswa, kuphela imifanekiso yefomathi ye-RAW inokufumaneka, ngaphandle kwenkxaso ye-ISP.
UFakelo lwe-App yeLibcamera esemthethweni

Hlela /boot/cmdline.txt kwaye wongeze cma=400M ekugqibeleni Iinkcukacha ezingakumbi: https://lists.libcamera.org/pipermail/libcamera-devel/2020-December/015838.html - Umfanekiso Ubonisa Umbala Amachaphaza Yongeza ikhowudi -denoise cdn_off ekupheleni komyalelo
Iinkcukacha ezingakumbi: https://github.com/raspberrypi/libcamera-apps/issues/19 - Akuphumelelanga ukuhlohla uMqhubi Nceda ujonge uguqulelo lwe-kernel, sibonelela kuphela ngomqhubi wenguqulo yamva nje yomfanekiso we-kernel xa le khamera ye-Pivarie-ty ikhutshiwe. Phawula: Ukuba ufuna ukuqokelela umqhubi wekernel wedwa, nceda bhekisa kwiphepha leDoc: https://www.arducam.com/docs/cameras-for-raspberry-pi/pivariety/how-to-install-kernel-driver-for-pivariety-camera/.
- Ayiphumelelanga ukuthumela ngaphandle i-fd 18
Ukuba ufumana impazamo efanayo, unokwenza ukhetho olungalunganga lomqhubi wegraphic. Nceda ulandele iphepha leAr-ducal Doc ukukhetha umqhubi wegrafiki ochanekileyo. - Tshintshela kwikhamera yendalo(raspistill njl.)
Hlela i file ye /boot/config.txt, yenza ngaphezulu-lay=arducam utshintsho kwi # dtoverlay=arducam Emva kokuba uhlengahlengiso lugqityiwe, kufuneka uqalise kwakhona iRaspberry Pi.
PHAWULA: Le modyuli yekhamera yenkxaso ivusa ngomqondiso wangaphandle, nceda ubhekisele kwiphepha leDoc ukufumana umyalelo https://www.arducam.com/docs/cameras-for-raspberry-pi/pivariety/how-to-access-pivariety-og02b10-2mp-color-global-shutter-camera-using-external-trigger-snapshot-mode/
Ukuba ufuna uncedo lwethu okanye ufuna ukwenza ngokwezifiso ezinye iimodeli zeekhamera zePi, zive ukhululekile ukuqhagamshelana nathi ngokusebenzisa
