Kāmera MIPI me te Kāmera USB
I ngā tau kua taha ake nei, kua whanake te tirohanga ā-roto mai i te kupu rongonui ki te hangarau whānui e whakamahia ana puta noa i ngā rāngai ahumahi, hauora, hokohoko, whakangahau, me te ahuwhenua. I ia wāhanga o tōna whanaketanga, kua whakarite te tirohanga ā-roto i te tipu nui o te maha o ngā atanga kāmera e wātea ana hei whiriwhiri. Heoi, ahakoa ngā whanaketanga hangarau, ko ngā atanga MIPI me USB tonu ngā momo e rua e tino rongonui ana mō te nuinga o ngā tono tirohanga ā-roto.
Atanga MIPI
Ko te MIPI (Mobile Industry Processor Interface) he paerewa tuwhera, he whakatakotoranga hoki i tīmatahia e te MIPI Alliance mō ngā tukatuka tono pūkoro.Ngā kōwae kāmera MIPIe kitea whānuitia ana i roto i ngā waea pūkoro me ngā papa, ā, e tautoko ana i ngā taumira whakamāramatanga teitei neke atu i te 5 miriona pika. Kua wehea te MIPI ki te MIPI DSI me te MIPI CSI, e rite ana ki ngā paerewa whakaatu ataata me te whakaurunga ataata. I tēnei wā, e whakamahia whānuitia ana ngā kōwae kāmera MIPI i roto i ētahi atu hua whakauru, pērā i ngā waea atamai, ngā taputapu hopu oro taraiwa, ngā kāmera pirihimana, ngā kāmera moroiti whakamāramatanga teitei, me ngā kāmera tirotiro whatunga.
Ko te MIPI Display Serial Interface (MIPI DSI ®) e tautuhi ana i tētahi atanga raupapa tere-teitei i waenga i tētahi tukatuka manaaki me tētahi kōwae whakaaturanga. Mā te atanga ka taea e ngā kaihanga te whakauru i ngā whakaaturanga mō te mahi teitei, te iti o te kai hiko, me te iti o te pokanoa hikohiko (EMI), me te whakaiti i te maha o ngā pine me te pupuri i te hototahi i waenga i ngā kaiwhakarato rerekē. Ka taea e ngā kaihoahoa te whakamahi i te MIPI DSI hei whakarato i te whakaaturanga tae kanapa mō ngā āhuatanga whakaahua me te ataata tino uaua, me te tautoko i te tuku i ngā ihirangi stereoscopic.
Ko te MIPI te atanga e whakamahia whānuitia ana i te mākete o ēnei rā mō te tuku whakaahua me te ataata i waenga i ngā kāmera me ngā taputapu manaaki. Nā te ngāwari o te whakamahi a te MIPI me tōna kaha ki te tautoko i te whānuitanga o ngā tono mahi-teitei. Kei roto hoki ngā āhuatanga kaha pērā i te ataata 1080p, 4K, 8K me tua atu me te whakaahua taumira-teitei.
He kōwhiringa tino pai te atanga MIPI mō ngā tono pēnei i ngā taputapu mooni mariko e mau ana ki te pane, ngā tono waka atamai, ngā pūnaha tohu, ngā waka rererangi kore utu, te tohu kanohi, te haumarutanga, ngā pūnaha tirotiro, me ētahi atu.
Atanga MIPI CSI-2
Ko te paerewa MIPI CSI-2 (MIPI Camera Serial Interface 2nd Generation) he atanga mahi-teitei, utu-whai hua, me te ngāwari ki te whakamahi. Ka tukuna e te MIPI CSI-2 he whānui mōrahi o te 10 Gb/s me ngā ara raraunga whakaahua e whā – ka taea e ia ara te whakawhiti raraunga tae atu ki te 2.5 Gb/s. He tere ake te MIPI CSI-2 i te USB 3.0, ā, he kawa pono tōna hei whakahaere i te ataata mai i te 1080p ki te 8K me tua atu. Hei tāpiri, nā te iti o te utu, he nui ake te whānui kupenga o te whakaahua a te MIPI CSI-2.
He iti ake ngā rauemi e whakamahia ana e te atanga MIPI CSI-2 mai i te PTM – nā ōna tukatuka matua-maha. Koinei te atanga kāmera taunoa mō Raspberry Pi me Jetson Nano. I ahu mai anō hoki i tēnei te wae kāmera Raspberry Pi V1 me V2.
Ngā Here o te Atanga MIPI CSI-2
Ahakoa he atanga kaha, rongonui hoki, he iti noa ngā herenga o te MIPI CSI. Hei tauira, ka whakawhirinaki ngā kāmera MIPI ki ngā taraiwa tāpiri hei mahi. Ko te tikanga he iti noa te tautoko mō ngā pūoko whakaahua rerekē mēnā kāore ngā kaihanga pūnaha whakauru e tino akiaki!
Ngā Painga o te MIPI:
He iti ake ngā rārangi tohu o te atanga MIPI i te atanga DVP. Nā te mea he tohu rerekētanga ngaohiko-iti, he iti te pokanoa e puta ana, ā, he kaha hoki te āheinga ārai-pokanoa. 800W me runga ake i ngā mea katoa e whakamahi ana i te atanga MIPI. Ka whakamahia e te atanga kāmera waea atamai te MIPI.
Me pēhea te mahi?
I te nuinga o te wā, ka tautoko te papa tino-kikī i roto i te pūnaha tirohanga i te MIPI CSI-2, ā, ka mahi tahi me te whānuitanga o ngā otinga pūoko atamai. Heoi anō, ka hototahi ki ngā papa CPU rerekē.
Ka tautoko a MIPI CSI-2 i te paparanga ā-tinana MIPI D-PHY hei whakawhitiwhiti kōrero ki te tukatuka tono, ki te Pūnaha rānei i runga i te Maramara (SoC). Ka taea te whakatinana i runga i tētahi o ngā paparanga ā-tinana e rua: MIPI C-PHY℠ v2.0, MIPI D-PHY℠ v2.5 rānei. Nō reira, ka taea te whakawhanui i tana mahi.
I roto i te kāmera MIPI, ka hopu te pūoko kāmera i tētahi whakaahua, ka tuku atu ki te kaihautū CSI-2. Ina tukuna te whakaahua, ka whakanohoia ki roto i te mahara hei anga takitahi. Ka tukuna ia anga mā roto i ngā hongere mariko. Kātahi ka wehea ia hongere ki ngā rārangi – ka tukuna takitahi. Nō reira, ka taea te tuku whakaahua katoa mai i te pūoko whakaahua kotahi – engari me ngā rerenga pika maha.
Ka whakamahia e MIPI CSI-2 ngā mōkihi mō te whakawhitiwhiti kōrero e whakauru ana i te hōputu raraunga me te mahi waehere whakatika hapa (ECC). Ka haere tētahi mōkihi kotahi mā te paparanga D-PHY, kātahi ka wehea ki te maha o ngā ara raraunga e hiahiatia ana. Ka mahi a D-PHY i te aratau tere-tiketike, ā, ka tukuna te mōkihi ki te kaiwhiwhi mā te hongere.
Kātahi ka whakaratohia ki te kaiwhiwhi CSI-2 te paparanga ā-tinana D-PHY hei tango me te wetewete i te mōkihi. Ka whakahokia te tukanga i ia anga i ia anga mai i te pūrere CSI-2 ki te kaihautū mā te whakatinanatanga whai hua me te iti o te utu.
Atanga USB
TeAtanga USBKo te tikanga he hononga tēnei i waenga i ngā pūnaha e rua – te kāmera me te PC. Nā te mea e mōhiotia whānuitia ana mō ōna āheinga mono-ā-ringa, ko te whiriwhiri i te atanga USB te tikanga ka taea e koe te poroporoaki ki ngā wā whakawhanake me ngā utu nui, roa hoki mō tō atanga tirohanga kua whakauruhia. He nui ngā herenga hangarau o te USB 2.0, te putanga tawhito. I te tīmatanga o te memeha haere o te hangarau, ka kore e hototahi ētahi o ōna wāhanga. I whakarewahia te USB 3.0 me ngā atanga USB 3.1 Gen 1 hei wikitoria i ngā herenga o te Atanga USB 2.0.
Ka whakakotahi te atanga USB 3.0 (me te USB 3.1 Gen 1) i ngā āhuatanga pai o ngā atanga rerekē. Kei roto i ēnei ko te hototahi mono-ā-ringa me te iti o te kawenga CPU. Ka whakanuia hoki e te paerewa ahumahi tirohanga o te USB 3.0 tōna pono mō ngā kāmera taumira teitei me te tere teitei.
He iti noa iho ngā taputapu tāpiri e hiahiatia ana, ā, he iti te whānui o te raraunga e tautokona ana – tae atu ki te 40 megabytes ia hekona. Ko te whānui mōrahi o te raraunga he 480 megabytes ia hekona. He 10 ngā wā tere atu tēnei i te USB 2.0, ā, e 4 ngā wā tere atu i te GigE! Mā ōna āheinga mono-ā-ringa ka taea te whakawhiti ngāwari i ngā taputapu tirohanga kua whakauruhia – kia māmā ai te whakakapi i tētahi kāmera pakaru.
Ngā Here o te Atanga USB 3.0
Ko te ngoikoretanga nui rawa atu o teUSB 3.0Ko te atanga kāore e taea te whakahaere i ngā pūoko taumira teitei i te tere teitei. Ko tētahi atu ngoikoretanga ko te taura tae noa ki te 5 mita te tawhiti mai i te tukatuka manaaki ka taea e koe te whakamahi. Ahakoa e wātea ana ngā taura roa ake, he "whakakaha" katoa kei roto. Me tirotirohia te pai o te mahi tahi a ēnei taura me ngā kāmera ahumahi mō ia take.
