Kāmera MIPI VS Kāmera USB

Ko te kōwhiringa o te atanga tino pai e whakawhirinaki ana ki ngā āhuatanga maha. Ā, ko MIPI me USB tonu ngā atanga kāmera rongonui e rua. Haere ki te ao o ngā atanga MIPI me USB, ka whakataurite i ia āhuatanga.

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.

Ko te kōwhiringa o tētahi atanga tino pai e whakawhirinaki ana ki ngā āhuatanga maha pērā i ngā whakaritenga tere anga/whanuitanga, te taumira, te pono o te whakawhiti raraunga, te roa o te taura, te uauatanga, me te – me te – te utu whānui. I roto i tēnei tuhinga, ka tirohia e mātou ngā atanga e rua kia pai ake ai te mārama ki ō rāua āheinga me ō rāua herenga.

Kāmera 720P

He tirohanga hōhonu ki ngā atanga MIPI me USB

 

He kāmera MIPI noa ihokōwae kāmerahe pūnaha rānei e whakamahi ana i te atanga MIPI hei whakawhiti whakaahua mai i te kāmera ki te tūāpapa manaaki. Hei whakataurite, ka whakamahia e te kāmera USB he atanga USB hei whakawhiti raraunga. Nā, kia mārama tātou ki ngā momo atanga MIPI me te USB me te wāhi e whakamahia ai.

Atanga MIPI

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.

Kāmera USB 5MP

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!

Atanga USB

Ko te atanga USB te hononga 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.

Atanga USB 3.0

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 o te atanga USB 3.0 ko te kore e taea te whakahaere i ngā pūoko taumira teitei i te tere tiketike. 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.
