3. Tatūnga
3.1 Hononga Miihini
Tūhonoa marietia te waeine kāmera ki tō papa Raspberry Pi mā te whakamahi i te Taura Papatahi Ngāwari (FFC) e tika ana. Me whakarite kia tika te whakatakotoranga hei ārai i te pakaru.
Pikitia 2: Ngā tohutohu hononga taura FFC mō ngā tauira Raspberry Pi.
- Mō te Rāhipere Pi 5: Me anga ngā hononga whakarewa o te taura FFC ki te tauranga Ethernet.
- Mō te Rāhipere Pi 4B/3B: Me anga ngā hononga whakarewa o te taura FFC ki te tauranga HDMI.
- Mō te Raspberry Pi Zero me te 2 W: Me anga iho ngā hononga whakarewa o te taura FFC ki raro (ki te papa matua). Kia mahara, me whakamahi he taura FFC angiangi mō ngā tauira Pi Zero.

3.2 Whirihoranga Rorohiko
Me whai whirihoranga pūmanawa motuhake te Arducam Camera Module 3 i runga i tō Raspberry Pi. Kua hangaia tēnei kōwae kāmera mō te puranga kāmera hou (libcamera/Picamera2) ā, kāore e hototahi ki te puranga kāmera tawhito (raspistill/raspivid).
- Tāutahia te pūnaha whakahaere Raspberry Pi: Me whakarite kei te whakahaerehia e tō Raspberry Pi tētahi putanga hou o te Raspberry Pi OS (hei tauira, Bullseye OS, hou ake rānei) e tautoko ana i te puranga kāmera hou.
- Whakahōu Pūnaha: Whakatuwheratia he tauranga ka whakahaere i ngā whakahau e whai ake nei hei whakahou i tō pūnaha:
sudo apt update && sudo apt upgrade - Tāutahia ngā taupānga-libcamera: Tāutahia ngā taupānga kāmera e tika ana:
Mō ngā tautuhinga kore-upoko, whakaarohia te `sudo apt install rpicam-apps-lite`.sudo apt install libcamera-apps - Whirihorahia te `config.txt`: Whakatikahia te whirihoranga whakaara file:
Kimihia, tāpirihia rānei ngā rārangi e whai ake nei:sudo nano /boot/firmware/config.txt
Tiaki ka puta atu i te ētita.camera_auto_detect=0
dtoverlay=imx708 - Whakahohehia te I2C: Mena kāore anō kia whakahohea, whakahohea te I2C mā te `raspi-config`:
Whakatere ki Kōwhiringa Atanga > I2C ā, whakahohea.sudo raspi-config - Whakaara Anō: Tīmata anō i tō Raspberry Pi kia whai mana ai ngā huringa:
sudo reboot
4. Nga Tohutohu Whakahaere
Kia angitu te tatūnga, ka taea e koe te whakahaere i te kāmera mā te whakamahi i ngā whakahau `libcamera`, i te whare pukapuka Picamera2 rānei.
4.1 Ngā Whakahau Taketake (libcamera)
- Rārangihia ngā Kāmera: Me manatoko kua kitea te kāmera:
Me kite koe i te putanga rite ki tēnei: `0 : imx708 [4608x2592 10-bit RGGB]`.rpicam-hello --list-cameras - Hopukia te Whakaahua Tūmau: Hopukia he whakaahua JPEG:
rpicam-jpeg -o test.jpg - Tuhia Ataata: Tuhia he ataata H.264:
(Ka tuhia mō te 10 hēkona)rpicam-vid -t 10000 -o video.h264
4.2 Arotahi Aunoa me te HDR
Ka tautoko te pūoko IMX708 i te arotahi aunoa (PDAF me te CDAF) me te HDR. Ko te tikanga ka whakahaerehia aunoatia ēnei āhuatanga e te puranga libcamera. Mō te mana whakahaere matatau, tirohia ngā tuhinga mana o libcamera me Picamera2 mō ngā tawhā me ngā tautuhinga motuhake.
5. Tiaki
He wāhanga hiko tino uaua te Arducam Camera Module 3. Whāia ēnei aratohu mō te tiaki tika:
- Te whakahaere: Me pupuri tonu te waeine kāmera mā ōna taha kia kore ai e pā ki te arotahi, ki te pūoko rānei.
- Te horoi: Whakamahia he kakahu ngohengohe, kore-miro, he pene horoi arotahi motuhake rānei hei horoi mārire i te arotahi mēnā e tika ana. Āta karohia ngā rauemi whakakoi, ngā matū kino rānei.
- Rokiroki: Whakaorangia te kaamera i roto i te waahi maroke, kore-puehu ka kore e whakamahia.
- Tiaki taura: Kia tino mohio kei piko rawa ngā taura FFC, kei pēhia rānei, nā te mea ka kino pea ngā hiko.
6. Te Raru
Mena ka pāngia koe e ngā raruraru me tō Arducam Camera Module 3, whakaarohia ēnei e whai ake nei:
- Hapa "Kāore he Kāmera e Wātea ana":
- Me tirotiro kua tika te whakaurunga o te taura FFC ki te waeine kāmera me te Raspberry Pi. Me hono katoa ngā hononga whakarewa, me anga atu ki te ahunga tika e ai ki te whakaahuatanga i te Wāhanga 3.1. Whakamātauria te huri i te taura ki ia pito, takitahi, ka whakaara anō.
- Me whakarite kia tika te whakatakotoranga o te `camera_auto_detect=0` me te `dtoverlay=imx708` ki roto i te `/boot/firmware/config.txt`.
- Whakaūtia kua whakahohea a I2C mā te `raspi-config`.
- Me whakarite kia whakahoutia tō pūnaha whakahaere Raspberry Pi, ā, kua tāutahia hoki ngā `libcamera-apps`.
- `Kua rahua te tohatoha a dmaHeap` Hapa: Ko tēnei hapa, e kitea pinepine ana i ngā tauira Pi tawhito (hei tauira, ko Pi 4 e whakahaere ana i te Bookworm), e tohu ana i te korenga o te mahara mō ngā ārai kāmera. Ahakoa te pikinga akeasinTērā pea ka āwhina te CMA (Contiguous Memory Allocator) o te g, engari ehara i te mea he otinga tuturu tonu. Whakaarohia te whakaiti i te taumira, te tere anga rānei, te whakamahi rānei i tētahi tauira Raspberry Pi hou ake mēnā ka taea.
- Ngā Take Kounga Whakaahua/Arotahi Kino:
- Tangohia te kiriata tiaki i te arotahi.
- Me whakarite kia tika te whakamarama o to taiao.
- Mō te mana arotahi aunoa motuhake, tirohia te tuhinga libcamera/Picamera2 mō ngā kōwhiringa arotahi ā-ringa.
- Hototahi ki te Pi Zero: Ahakoa he hototahi, kia tino mohio kei te whakamahi koe i te taura FFC tika, angiangi hoki i hangaia mō te hononga kāmera iti ake o te Pi Zero.
