一, kamera zindege ni ikihe?

Igihe-cyindege (tof) kamera ni ubwoko bwikoranabuhanga ryimbitse ripima intera iri hagati ya kamera nibintu bireba kugirango bifate umwanya wo gutembera kubintu no gusubira kuri kamera. Bakunze gukoreshwa muburyo butandukanye nko guhura, robotike, 3D scanning, ibimenyetso byerekana ibimenyetso, nibindi byinshi.

Kamera ya tofKora mugusohora ikimenyetso cyoroshye, mubisanzwe urumuri rwamazi, no gupima igihe bisaba ibimenyetso byo kuvana inyuma nyuma yo gukubita ibintu muri kariyaho. Iki gihe cyo gupima noneho gikoreshwa mukubara intera kubintu, bikora ikarita yimbitse cyangwa igishushanyo cya 3d cyerekana.

Igihe cya kamera yindege

Ugereranije nubundi buryo bwo kumva tekinoroji yimbitse nkicyerekezo cyumucyo cyangwa stereo icyerekezo cya vef, kamera ya tof itanga ibyiza byinshi. Batanga amakuru yimbitse-nyayo, bafite igishushanyo mbonera ugereranije, kandi barashobora gukora muburyo butandukanye bwo gucana. Kamera ya Tof nayo irasa kandi irashobora guhuzwa mubikoresho bito nka terefone, ibinini, nibikoresho byambaye ubusa.

Gusaba kamera ya tof ni zitandukanye. Muri rusange, kamera ya tof irashobora kumenya neza ibintu byimbitse no kunoza realism yibintu bifatika byashyizwe mwisi nyayo. Muri robo, bifasha robot kugirango babone ibibakikije no kugendana inzitizi neza. Muri 3d scanning, kamera ya tof irashobora gufata vuba geometrie yibintu cyangwa ibidukikije kubikorwa bitandukanye nkibigaragara, gukina, cyangwa icapiro rya 3. Zikoreshwa kandi mubisabwa biometric, nko kumenyekana mumaso cyangwa ibimenyetso byerekana amaboko.

二,Ibice byigihe cya kamera yindege

Igihe-cyindege (tof) kamerabigizwe nibigize byinshi byingenzi bikorana kugirango bishobore kwikorera ubujyakuzimu no gupima intera. Ibigize byihariye birashobora gutandukana bitewe nigishushanyo nuwabikoze, ariko hano hari ibintu byibanze mubisanzwe biboneka muri sisitemu ya Tof:

Inkomoko yoroheje:

Kamera ya Tof Koresha isoko yoroheje kugirango isohoze ikimenyetso cyoroshye, mubisanzwe muburyo bwa infrared (IR). Inkomoko yumucyo irashobora kuba iyobowe (diode yoroheje) cyangwa diode ya laser, bitewe nigishushanyo cya kamera. Umucyo wasohotse ugana mubintu aho.

Optics:

Lens ikusanya umucyo ugaragara kandi amashusho agaragaza ibidukikije sensor (yindege yindege yibanze). Itsinda rya optique-pass filteri gusa rishyiraho urumuri hamwe nuburebure bumwe nkishami ririza. Ibi bifasha guhagarika itara ridakenewe kandi rigabanya urusaku.

SENSOR:

Uyu niwo mutima wa kamera ya tof. Buri pigiseli apima igihe umucyo wateye kugirango uve mu ishami rishinzwe kurwanya (laser cyangwa uyobowe) ku kintu hanyuma usubire mu ndege yibanze.

Umuzunguruko w'igihe:

Gupima igihe-cyo guhaguruka neza, kamera ikenera umuzunguruko. Iyi myuga igenzura ibimenyetso byoroheje hanyuma itamenya igihe bisaba urumuri rwo gutembera kubintu hanyuma usubire kuri kamera. Ihuza ibikorwa byo guhuriza hamwe no gutahura kugirango habeho ibipimo nyabyo.

Guhindura:

BimweKamera ya tofShyiramo uburyo bwo guhinduranya kugirango utezimbere ukuri no gukomera kubipimo bya kure. Iyi kamera modulate yerekana ibimenyetso byasohotse hamwe nuburyo runaka cyangwa inshuro. Imyifatire ifasha gutandukanya umucyo wasohotse mu zindi nkomoko y'ibidukikije kandi itezimbere ubushobozi bwa kamera bwo gutandukanya ibintu bitandukanye.

Ubujyakuzimu bwa Algorithm:

Guhindura igihe-cyibipimo byindege mumakuru yimbitse, kamera ya tof ikoreshwa algoriithms nziza. Ibi bisobanuro bya algorithms byasesengura amakuru yigihe yakiriwe na Photodetetector no kubara intera iri hagati ya kamera nibintu biri mubintu. Ubujyakuzimu bukabije bwo kubara akenshi burimo kwishyura ibintu nkumuvuduko wo gutangaza urumuri, igihe cyo gusubiza gusa, hamwe nibibazo byo kwivanga.

Uburebure bwamakuru:

Iyo kubara ubujyakuzimu bikorwa, kamera ya tof itanga ubujyakuzimu. Ibi bisohora birashobora gufata imiterere yikarita yimbitse, igicu, cyangwa 3D yerekana ibyabaye. Amakuru yimbitse arashobora gukoreshwa na porogaramu na sisitemu kugirango ukore imikorere itandukanye nkikintu gikurikirana, ukuri kwiyongera, cyangwa imirongo ya robo.

Ni ngombwa kumenya ko gushyira mu bikorwa hamwe n'ibigize kamera ya tof birashobora gutandukana kubantu batandukanye nicyitegererezo. Iterambere mu ikoranabuhanga rishobora kumenyekanisha ibiranga no kuzamura kunoza imikorere n'ubushobozi bya sisitemu ya kamera.

三, porogaramu

Porogaramu

Igihe-cy'indegezikoreshwa mugufasha n'umutekano mu bikorwa bya porogaramu byateye imbere nk'Umutekano ukoreramo, precrash gutahura no gusaba mu nzu nko hanze (oop) gutahura (oop) gutahura.

Imikorere yimashini yumuntu no gukina

As Igihe-cy'indegeTanga amashusho intera mugihe nyacyo, biroroshye gukurikirana imigendekere yabantu. Ibi bituma imikoranire mishya nibikoresho byabaguzi nka televiziyo. Undi ngingo ni ugukoresha ubu bwoko bwa kamera kugirango usangire n'imikino ku mukino wumukino wa videwo. Urusekuru rwa kabiri rwa Kinect Porogaramu ukoresheje Icyerekezo cya mudasobwa hamwe na teyerisiyo yerekana ibimenyetso.

Guhanga kandi Intel itanga ubwoko busa bwibimenyetso bisa nibimenyetso byindege-yindege kugirango ucengeze, Senz3d ishingiye kuri kamera yimbitse 325 ya kamera ya softkintic. Inzozi na PMD tekinoroji ya 3D zometseho amashusho yimbitse yo kugenzura ibimenyetso bya hafi nka-kimwe na-mudasobwa ya picco na picco mols).

Kamera ya Smartphone

Amashanyarazi menshi akubiyemo igihe-cyindege. Ibi bikoreshwa cyane kugirango utezimbere ubwiza bwamafoto utanga software ya kamera hamwe namakuru ajyanye nimbere. Terefone ya mbere igendanwa yo gukoresha ikoranabuhanga nk'iryo ni LG G3, yasohowe mu ntangiriro za 2014.

Gupima no kwerekwa imashini

Ibindi bikorwa ni imirimo yo gupima, eg kumafaranga yuzuye muri silos. Mu imashini yinganda zerekanwa, igihe-cyindege gifasha gushyira mubikorwa no kumenya ibintu kugirango bikoreshwe na robo, nkibintu bitambuka kuri convoye. Igenzura ryumuryango rirashobora gutandukanya amatungo ndetse nabantu bagera kumuryango.

Robotics

Ubundi buryo bwo gukoresha aya kamera ni umurima wa robo: Imashini zigendanwa zirashobora kubaka ikarita yabo vuba cyane, ibafasha kwirinda inzitizi cyangwa kurikira umuntu ukomeye. Mugihe intera yo kubara byoroshye, gusa imbaraga zina zikoreshwa. Kubera ko izi kamera nazo zishobora gukoreshwa mugupima intera, amatsinda yo guhatanira kwa robot ya mbere yamenyekanye kugirango akoreshe ibikoresho bya gahunda yigenga.
