PAMBUKA

• Babagan Arducam
  Arducam wis dadi desainer profesional lan produsen kamera SPI, MIPI, DVP, lan USB wiwit 2012. Kita uga nawakake desain turnkey lan layanan solusi manufaktur kanggo pelanggan sing pengin produke unik.
• Babagan Kamera Pivariety Iki
  Arducam Pivariety minangka solusi kamera Raspberry Pi kanggo njupuk advantage nggunakake fungsi hardware ISP sawijining. Modul kamera Pivariety nggawe pangguna entuk kinerja sing luwih apik lan macem-macem pilihan lensa lan kamera sing luwih akeh. Ing tembung liyane, Pivariety nembus watesan saka driver kamera lan modul kamera sing didhukung resmi tertutup (V1 / V2 / HQ).

Modul kamera Pivariety ndadekake ISP sing disetel kanthi apik kanthi Auto Exposure, Auto White Balance, Auto Gain Control, Lens Shading Correction, lsp. Seri kamera iki nggunakake kerangka kamera lib, ora bisa didhukung dening Raspistill, lan cara kanggo ngakses kamera punika lib kamera SDK (kanggo C ++) / lib kamera-isih / lib kamera-vid / Gstreamer.

Kamera Rana Global Warna Pivariety OGO2B10 iki dipindhah karo Kamera Raspberry Pi, sing ngilangi artefak rana gulung kanggo njupuk obyek obah kanthi kecepatan dhuwur ing gambar sing cetha warna.

SPESIFIKASI

SOFTWARE

1. Instalasi Driver
   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
   ./install_pivariety_pkgs.sh -p kernel_driver
   penet y kanggo urip maneh
   CATETAN: Instalasi driver kernel mung didhukung dening versi paling anyar 5.10. Kanggo versi kernel liyane, bukak kaca Doc: 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
   Sampeyan uga bisa ngunjungi kaca doc iki kanggo ngrujuk menyang sambungan hardware:
   https://www.arducam.com/docs/cameras-for-raspberry-pi/pivariety/pivarietyog02b10-2mp-color-global-shutter-camera-module/
2. Tes Driver lan Kamera
   Sawise rampung instalasi hardware lan instalasi driver, sampeyan bisa nyoba manawa kamera bisa dideteksi utawa aktif.
   • View Status Driver lan Kamera
   dmesg | grep arducam
   Bakal nampilake macem-macem arducam yen driver diinstal kanthi sukses lan versi firmware yen kamera bisa dideteksi.
   Tampilan kudu probe gagal yen kamera ora bisa dideteksi, sampeyan bisa uga kudu mriksa sambungan pita, banjur urip maneh Raspberry Pi.
   • View Node Video
   Modul kamera Pivariety ditiru minangka piranti video standar ing simpul / dev / video *, supaya sampeyan bisa nggunakake printah ls kanggo dhaptar isi ing folder / dev.
   ls /dev/video* -l
   Amarga modul kamera sing tundhuk V4L2, sampeyan bisa nggunakake kontrol V4l2 kanggo dhaptar spasi warna, resolusi, lan frame rate sing didhukung.
   v4l2-ctl –daptar-format-ext
   CATETAN: Senajan antarmuka V4L2 didhukung, mung gambar format RAW bisa dijupuk, tanpa support ISP.
   
3. Instalasi Aplikasi Libcamera Resmi
   ./install_pivariety_pkgs.sh -p libcamera_dev
   ./install_pivariety_pkgs.sh -p libcamera_apps
4. Njupuk Gambar lan Rekam Video
   • Jupuk gambar
   Kanggo example, praview kanggo 5s lan nyimpen gambar jenenge test.jpg
   lib kamera-isih -t 5000 -o test.jpg
   • Rekam video
   Kanggo example, ngrekam video H.264 10s karo ukuran pigura1920W × 1080H
   lib camera-vid -t 10000 -jembaré 1920 -dhuwur 1080 -o test.h264
   CATETAN: Format H.264 mung ndhukung resolusi 1920 × 1080 lan ngisor.
   • Instalasi gstreamer Plugin
   Instal gstreamer
   nganyari sudo apt
   sudo apt nginstal -y gstreamer1.0-tools
   Praview
   gst-launch-1.0 libcamerasrc ! 'video/xraw,width=1920,dhuwur=1080' ! videoconvert! autovideosink

3.  Gagal nginstal Driver
   Mangga dipriksa versi kernel, kita mung nyedhiyakake driver kanggo gambar versi kernel resmi paling anyar nalika kamera Pivariety iki dirilis.
   Cathetan: Yen sampeyan pengin ngumpulake driver kernel dhewe, waca kaca Doc: https://www.arducam.com/docs/cameras-for-raspberry-pi/pivariety/how-to-installkernel-driver-for-pivariety-camera/
4. Gagal ngimpor fd 18 mungkasi disebut sawise mbuwang Kayata saka 'std :: runtime_error' apa (): gagal ngimpor fd 18 Aborted Yen sampeyan nemokake kesalahan padha, sampeyan bisa nggawe pilihan salah bab driver grafis. Tututi kaca Arducam Doc kanggo milih driver grafis sing bener.
   Yen sampeyan nemokake kesalahan sing padha, sampeyan bisa uga salah milih babagan driver grafis. Tututi kaca Arducam Doc kanggo milih driver grafis sing bener.
5. Ngalih menyang kamera asli (raspistill lsp.)
   Sunting ing file saka /boot/config.txt, nggawe dtoverlay = arducam pangowahan kanggo # dtoverlay = arducam Sawise modifikasi rampung, sampeyan kudu urip maneh Raspberry Pi.
   sudo urip maneh

CATETAN: Modul kamera iki ndhukung pemicu liwat sinyal eksternal, waca kaca Doc kanggo njaluk instruksi https://www.arducam.com/docs/cameras-for-raspberry-pi/pivariety/how-toaccess-pivariety-og02b10-2mp-color-globalshutter-camera-using-external-trigger-snapshotmode/
