Kodi kamera ya nthawi ndi yotani? Kodi ndi kamera yomwe imagwira kuthawa kwa ndege? Kodi ili ndi chochita ndi ndege kapena ndege? Inde, ndi nthawi yayitali!

TOF ndi nthawi ya nthawi yomwe imatenga chinthu, tinthu tomwe timayenda mtunda wautali. Kodi mumadziwa kuti dongosolo la soser la soser limagwira ntchito? Dongosolo la nthawi yake ndi lofanana!

Pali mitundu yambiri ya ma show-okwera nthawi yayitali, koma ambiri ndi makamera okwera nthawi ndi ma laser, omwe amagwiritsa ntchito ukadaulo wotchedwa Lidar (kuwunika) Kuyeza kuya kwa mfundo pofuwula ndi kuwala kopepuka.

Zambiri zomwe zimapangidwa ndikugwidwa pogwiritsa ntchito masensa a TOF ndizothandiza kwambiri monga momwe zimathandizira pakuyenda mayendedwe, malo okhazikika pamasamba (nthawi yomweyo ma porgation) a algorithms, ndi zina zambiri.

Dongosolo ili limagwiritsidwa ntchito kwambiri m'mabotolo, magalimoto oyendetsa okha, ndipo ngakhale pano pafoni yanu. Mwachitsanzo, ngati mukugwiritsa ntchito huawei p30 pro, hamo rx17 pro, lg g8 woonda, ndi foni yanu.

Kamera ya TOF

2. Kodi ma sensor aiwor amagwira ntchito bwanji?

Tsopano, tikufuna kufotokozera mwachidule zomwe sensor youluka ili ndi momwe imagwirira ntchito.

TambalaSensors amagwiritsa ntchito zingwe zazing'ono kuti atulutse kuwala, komwe kuunika kumawomba chinthu chilichonse ndikubwerera ku sensor. Kutengera nthawi ya kutuluka pakati pa kutulutsa kwa kuwala ndi kubwerera ku sensor mutawonetsedwa ndi chinthu, sensor imatha kuyeza mtunda pakati pa chinthu ndi sensor.

Masiku ano, tiona njira ziwiri zomwe zimagwiritsa ntchito TOF nthawi kuti tipeze mtunda ndi kuya kwakuti: Pogwiritsa ntchito nthawi, ndikugwiritsa ntchito gawo la matalikidwe.

Gwiritsani ntchito malo okhazikika

Mwachitsanzo, imagwira ntchito powunikira chandamale ndi laser, ndiye kuyesa kuwunika komwe kuli ndi scanner, kenako ndikugwiritsa ntchito liwiro la chinthucho kuti muwerengere mtunda woyenda. Kuphatikiza apo, kusiyana kwa laser nthawi yobwerera ndi mafunde kumagwiritsidwa ntchito kupanga mawonekedwe olondola a digito 3D ndi mawonekedwe a chandamale, ndikuwona mawonekedwe ake.

Monga mukuwonera pamwambapa, kuwala kwa Laser wachotsedwa ntchito kenako ndikuchotsa chinthucho ku sensor. Ndi nthawi ya laser, makamera a TF amatha kuyeza mtunda wolondola munthawi yochepa omwe amaperekedwa mwachangu. .

(Kuthamanga kwa nthawi yowala x / 2

TOF imatembenuza mtunda

Monga mukuwonera, nthawi idzayamba pomwe kuwalako kwatha, ndipo wolandirayo akalandira kuwala kobwerera, nthawiyo ibwezerani nthawi imeneyo. Mukachotsa kawiri, "nthawi yakuuluka" imapezeka, ndipo kuthamanga kwa kuwala kumatha kuwerengedwa mosavuta pogwiritsa ntchito njira yomwe ili pamwambapa. Mwanjira imeneyi, mfundo zonse pamtundu wa chinthu zitha kutsimikizika.

Gwiritsani ntchito njira yosinthira

Kenako,TambalaItha kugwiritsanso ntchito mafunde osalekeza kuti azindikire gawo lomwe likuwonetsedwa kuti mudziwe kuya ndi mtunda.

Gawo la gawo likugwiritsa ntchito funde

By modulating the amplitude, it creates a sinusoidal light source with a known frequency, allowing the detector to determine the phase shift of the reflected light using the following formula:

Komwe c ndi kuthamanga kwa kuwala (c = 3 × 10 ^ 8 m / s), ndipo f ndi pafupipafupi, chilichonse pa sensor chitha kuwerengedwa mozama.

Zinthu zonsezi zimathamanga kwambiri pamene tikugwira ntchito kuthamanga kwa kuwala. Kodi mungaganizire molondola komanso kuthamanga ndi ma sensor omwe amatha kudziwa? Ndiloleni ndipereke chitsanzo, kuwala kumayenda mwachangu kwa makilomita 300,000 pa sekondi imodzi, ngati chinthu chatha pakati panu, kupatulapo pakati pa kuwalaku ndikubwerera kumasekondi 33003333333333333333333333333333333333333333. Oo! Osati kutchulanso, kuchuluka kwa zomwe zinagwidwa kudzakupatsani chithunzi cholondola cha pixel iliyonse m'chithunzichi.

Mosasamala mfundo zomwe zimagwiritsidwa ntchito, kupereka gwero lowunikira lomwe zinthu zonse zimalola sensor kuti mudziwe kuya kwa mfundo zonse. Zotsatira zake zimakupatsani mapu oyenera pomwe pixel iliyonse imayang'ana mtunda wopita kumalo ofanana. Chotsatirachi ndi chitsanzo cha gawo la TOF:

Chitsanzo cha mawonekedwe a TOF

Tsopano popeza tikudziwa kuti tinthu timagwira ntchito, bwanji zili bwino? Chifukwa Chiyani Kugwiritsa Ntchito? Ndi ziti zabwino? Osadandaula, pali zabwino zambiri pakugwiritsa ntchito sensor ya ty, koma zachilendo pali zoperewera.

3. Ubwino wogwiritsa ntchito nthawi yayitali

Kuyeza kolondola komanso mwachangu

Poyerekeza ndi masensa ena monga ultrasound kapena lasers, masensa a nthawi ya nthawi amatha kulemba chithunzi cha mawonekedwe a 3 mwachangu. Mwachitsanzo, kamera ya TOF imatha kuchita izi kamodzi kokha. Osati zokhazo, sensor ya tyf imatha kuzindikira zinthu molondola panthawi yochepa ndipo sizikukhudzidwa ndi chinyezi, kuthamanga kwa mpweya, kupangitsa kuti ikhale yoyenera kwa onse mkati.

mtunda wautali

Popeza maselo a TOF amagwiritsa ntchito a Lasers, amathanso kuyeza mtunda wautali ndi zolondola kwambiri. Ma sylars a TOF amasinthasintha chifukwa amatha kudziwa pafupi ndi zinthu zonse ndi kukula kwake.

Zimasinthanso mwachidule kuti mumatha kusintha masinthidwe a dongosololi kuti muthe kugwiritsa ntchito bwino, komwe mungasankhe mitundu yotumiza ndi mandala ndi mandala omwe angafune.

Chitetezo

Kuda nkhawa kuti laser kuchokeraTambalasensor idzakhumudwitsa maso anu? Osadandaula! Zojambula zambiri za TOF tsopano zimagwiritsa ntchito madzi otsika kwambiri ngati gwero lowunikira ndikuyendetsa ndi ma pulleted osinthika. Sensor imakumana ndi mtundu wa chitetezo 1 cha laser kuti zitsimikizire kuti zili bwino kwa diso la munthu.

mtengo wothandiza

Poyerekeza ndi ukadaulo wina wa 3D ukuyamwa monga makina owoneka bwino a kamera kapena mtundu wa laser, masensa a TF ndi otsika mtengo kwambiri poyerekeza ndi iwo.

Ngakhale kuti pali zoperewera zonsezi, boof akadali odalirika komanso njira yofulumira kwambiri yolanda zambiri za 3D.

4. Zofooka za TOF

Ngakhale kuti taf ili ndi zabwino zambiri, ilinso ndi malire. Zofooka zina za TOF zimaphatikizapo:

• Kuwala

Ngati malo owala kwambiri ali pafupi kwambiri ndi sensor yanu ya TOF, atha kuwalitsa kwambiri olandila ndikupanga zojambulajambula komanso zomwe mumawonetseratu, chifukwa senso ya tcher yanu imangofunika kuwunikira nthawi yomwe ikukonzekera.

• Zowonetsera zambiri

Mukamagwiritsa ntchito maselo a TOF pa ngodya ndi mawonekedwe a conceve, amatha kuyambitsa ziwonetsero zosafunikira, chifukwa kuwalako kumatha nthawi yovuta, kusovutsa muyeso.

• Kuwala kozungulira

Kugwiritsa ntchito kamera ya TOF panja pakuwala kowala kumatha kusintha zakunja. Izi zimachitika chifukwa cha kukula kwa kuwala kwa dzuwa zomwe zimayambitsa pixer pixels kuti mukhumudwitse, ndikupangitsa kuti zisaone kuwala kwenikweni zomwe zimawonetsedwa kuchokera ku chinthucho.

• Theliro

Ma tons andTOF LINSitha kugwiritsidwa ntchito pamapulogalamu osiyanasiyana. Kuchokera pamapu a 3D, odzipereka a mafakitale, magalimoto odziletsa, ulimi, kuzindikiridwa, kuyerekezera, kuyeza chinthu chovomerezeka! Mapulogalamu a ukadaulo wa TFO satha.

Mutha kulumikizana nafe chifukwa cha zosowa za TOF.
