He aha te wā o ngā kāmera rere?

Ko ngā kāmera Time-of-flight (ToF) he momo hangarau ine hohonu e ine ana i te tawhiti i waenga i te kāmera me ngā mea i roto i te tirohanga mā te whakamahi i te wā e pau ana kia haere te mārama ki ngā mea, kia hoki mai anō ki te kāmera. He mea whakamahi noa ēnei i roto i ngā momo tono pēnei i te mooni whakanui, te karetao, te matawai 3D, te mohio ki ngā tohu, me ētahi atu.

Ngā kāmera ToFMā te tuku i tētahi tohu mārama, ko te mārama whero-whero te tikanga, ka ine i te wā e hoki whakamuri ai te tohu i muri i te pā ki ngā mea o te tirohanga. Kātahi ka whakamahia tēnei ine wā hei tatau i te tawhiti ki ngā mea, ka hangaia he mahere hohonu, he whakaaturanga 3D rānei o te tirohanga.

Te wā o ngā kāmera rere

Ki te whakaritea ki ētahi atu hangarau ine hohonu pērā i te mārama hanganga, te tirohanga ā-reo rānei, he maha ngā painga o ngā kāmera ToF. Ka whakaratohia e rātou ngā mōhiohio hohonu i te wā tūturu, he hoahoa māmā noa iho, ā, ka taea te mahi i roto i ngā āhuatanga mārama rerekē. He iti hoki ngā kāmera ToF, ā, ka taea te whakauru ki ngā taputapu iti ake pērā i ngā waea atamai, ngā papa, me ngā taputapu mau.

He rerekē ngā whakamahinga o ngā kāmera ToF. I roto i te mooni whakanui, ka taea e ngā kāmera ToF te kite tika i te hohonutanga o ngā mea me te whakapai ake i te mooni o ngā mea mariko kua whakanohoia ki te ao tūturu. I roto i te karetao, ka taea e ngā karetao te kite i ō rātou taiao me te whakatere i ngā arai kia pai ake te whai hua. I roto i te matawai 3D, ka taea e ngā kāmera ToF te hopu tere i te āhua o ngā mea, ngā taiao rānei mō ngā kaupapa rerekē pēnei i te mooni mariko, te petipeti, te tā 3D rānei. Ka whakamahia hoki ēnei i roto i ngā whakamahinga koiora, pēnei i te mohio kanohi, te mohio ringa rānei.

二、Ngā wāhanga o te wā rere o ngā kāmera

Ngā kāmera wā-o-te-rere (ToF)he maha ngā wāhanga matua e mahi tahi ana hei whakahohe i te ine hohonu me te ine tawhiti. Tērā pea ka rerekē ngā wāhanga motuhake i runga i te hoahoa me te kaihanga, engari anei ngā wāhanga matua e kitea ana i roto i ngā pūnaha kāmera ToF:

Pūtake Mārama:

Ka whakamahia e ngā kāmera ToF tētahi pūtake mārama hei tuku i tētahi tohu mārama, ko te nuinga he mārama infrared (IR). Ka taea te pūtake mārama he LED (Light-Emitting Diode) he taiaho rānei, i runga i te hoahoa o te kāmera. Ka haere te mārama e tukuna ana ki ngā mea o roto i te tirohanga.

Ngā tirohanga:

Ka kohia e te arotahi te mārama whakaata, ka whakaahuahia te taiao ki runga i te pūoko whakaahua (te huinga papa arotahi). Ka tukuna noa e te tātari whakawhiti-roopu whatu te mārama he rite te roangaru ki te waeine whakamārama. Ka āwhina tēnei ki te pehi i te mārama kāore e pā ana, me te whakaiti i te haruru.

Pūoko whakaahua:

Koinei te ngako o te kāmera TOF. Ka ine ia pika i te wā e haere ana te mārama mai i te wae whakamārama (reera, LED rānei) ki te mea, ā, hoki atu ana ki te rarangi papa arotahi.

Te Huringa Wā:

Hei ine tika i te wā rere, me whai porowhita wā tika te kāmera. Mā tēnei porowhita ka whakahaere te tukunga o te tohu mārama, ka kitea hoki te wā e pau ana kia haere te mārama ki ngā mea, kātahi ka hoki mai ki te kāmera. Ka tukutahi i ngā tukanga tukunga me te kimi kia tika ai ngā ine tawhiti.

Te whakarerekētanga:

ētahiNgā kāmera ToFwhakauru i ngā tikanga whakarerekētanga hei whakapai ake i te tika me te pakari o ngā inenga tawhiti. Ka whakarerekē ēnei kāmera i te tohu mārama e tukuna ana me tētahi tauira, auau rānei. Ka āwhina te whakarerekētanga ki te wehewehe i te mārama e tukuna ana mai i ētahi atu puna mārama taiao, ā, ka whakarei ake i te kaha o te kāmera ki te wehewehe i waenga i ngā mea rerekē i roto i te tirohanga.

Rautaki Tātai Hōhonu:

Hei huri i ngā inenga wā-rere ki ngā mōhiohio hohonu, ka whakamahia e ngā kāmera ToF ngā rauropi matatau. Ka tātarihia e ēnei rauropi ngā raraunga wā i whiwhi mai i te pūoko whakaahua, ā, ka tatau i te tawhiti i waenga i te kāmera me ngā mea i roto i te tirohanga. He maha ngā wā ka uru atu ki ngā rauropi tatau hohonu te utu mō ngā āhuatanga pēnei i te tere horapa o te mārama, te wā urupare a te pūoko, me te pokanoa o te mārama taiao.

Putanga Raraunga Hōhonu:

Kia oti te tatau i te hohonutanga, ka tukuna e te kāmera ToF he putanga raraunga hohonu. Ka taea e tēnei putanga te tango i te āhua o tētahi mapi hohonutanga, he kapua pūwāhi, he whakaaturanga 3D rānei o te tirohanga. Ka taea te whakamahi i ngā raraunga hohonutanga e ngā tono me ngā pūnaha hei whakahohe i ngā mahi maha pēnei i te aroturuki i ngā mea, te mooni whakanuia, te whakatere karetao rānei.

He mea nui kia mōhiotia ko te whakatinanatanga me ngā wāhanga motuhake o ngā kāmera ToF ka rerekē pea i waenga i ngā kaihanga me ngā tauira rerekē. Tērā pea ka whakauruhia mai e ngā whanaketanga hangarau ētahi atu āhuatanga me ngā whakarei ake hei whakapai ake i te mahi me ngā āheinga o ngā pūnaha kāmera ToF.

三, Tono

Ngā tono motuka

Ngā kāmera wā-o-te-reree whakamahia ana i roto i ngā mahi āwhina me te haumaru mō ngā tono motuka matatau pēnei i te haumaru hikoi hohe, te kimi i mua i te tukinga me ngā tono o roto pēnei i te kimi i waho o te tūranga (OOP).

Te whakamahinga o ngā kāmera ToF

Ngā atanga tangata-mīhini me te petipeti

As ngā kāmera wā-o-te-rereMā te whakarato i ngā whakaahua tawhiti i te wā tūturu, he māmā noa iho te whai i ngā nekehanga o te tangata. Mā tēnei ka taea ngā taunekeneke hou me ngā taputapu kaihoko pēnei i ngā pouaka whakaata. Ko tētahi atu kaupapa ko te whakamahi i tēnei momo kāmera hei taunekeneke me ngā kēmu i runga i ngā papatohu kēmu ataata. Ko te pūoko Kinect o te whakatipuranga tuarua i whakaurua tuatahitia ki te papatohu Xbox One i whakamahi i te kāmera wā-o-te-rere mō tana whakaahua tawhiti, ka taea ai ngā atanga kaiwhakamahi taiao me ngā tono petipeti mā te whakamahi i te tirohanga rorohiko me ngā tikanga tohu.

Ka whakaratohia hoki e Creative me Intel tētahi momo kāmera tauwhitiwhiti nekehanga wā-o-te-rere rite tonu mō te petipeti, ko te Senz3D i ahu mai i te kāmera DepthSense 325 a Softkinetic. Ka taea e Infineon me PMD Technologies te whakahohe i ngā kāmera hohonu 3D iti kua whakauruhia mō te whakahaere nekehanga tata o ngā taputapu kaihoko pēnei i ngā PC me ngā pona katoa-i-te-kotahi (ngā kāmera Picco flexx me Picco monstar).

Ngā kāmera waea atamai

He maha ngā waea atamai kei roto ngā kāmera wā-o-te-rere. Ko te nuinga o ēnei e whakamahia ana hei whakapai ake i te kounga o ngā whakaahua mā te whakarato i ngā mōhiohio ki te pūmanawa kāmera mō te papamuri me te papamuri. Ko te waea pūkoro tuatahi i whakamahi i tēnei hangarau ko te LG G3, i tukuna i te tīmatanga o te tau 2014.

Te ine me te tirohanga mīhini

Ko ētahi atu whakamahinga he mahi ine, hei tauira, mō te teitei whakakī i roto i ngā silo. I roto i te tirohanga mīhini ahumahi, ka āwhina te kāmera wā-o-te-rere ki te whakarōpū me te kimi i ngā mea hei whakamahi mā ngā karetao, pērā i ngā mea e haere ana i runga i te kaikawe. Ka taea e ngā mana whakahaere tatau te wehewehe ngāwari i waenga i ngā kararehe me ngā tāngata e tae atu ana ki te tatau.

Robotics

Ko tētahi atu whakamahinga o ēnei kāmera ko te ao o te karetao: Ka taea e ngā karetao pūkoro te hanga mapi o ō rātou taiao i roto i te wā poto, ka taea ai e rātou te karo i ngā arai, te whai rānei i tētahi tangata ārahi. Nā te mea he māmā te tatau i te tawhiti, he iti noa te mana rorohiko e whakamahia ana. Nā te mea ka taea hoki te whakamahi i ēnei kāmera hei ine i te tawhiti, kua mōhiotia ngā tīma mō te Whakataetae Robotics TUATAHI ki te whakamahi i ngā taputapu mō ngā mahi motuhake.

Te āhua o te whenua

Ngā kāmera ToFkua whakamahia hei tiki tauira teitei mamati o te āhua o te mata o te Ao, mō ngā rangahau i te āhua whenua.
