Time Kamera yo kuguruka ni ikihe?

Kamera-y-indege (ToF) kamera ni ubwoko bwikoranabuhanga-ryimbitse ryapima intera iri hagati ya kamera nibintu bigaragara mugukoresha igihe bifata kugirango urumuri rugende mubintu hanyuma usubire kuri kamera. Bakunze gukoreshwa mubikorwa bitandukanye nko kongera ukuri, robotike, gusikana 3D, kumenyekanisha ibimenyetso, nibindi byinshi.

Kamera ya ToFkora mukurekura urumuri rwumucyo, mubisanzwe urumuri rwa infragre, no gupima igihe bifata kugirango ikimenyetso gisubire inyuma nyuma yo gukubita ibintu mumwanya. Iki gihe cyo gupima noneho gikoreshwa mukubara intera yibintu, gukora ikarita yimbitse cyangwa 3D igereranya.

Igihe cyo gufata kamera

Ugereranije nubundi buryo bwimbitse-bwenge nkumucyo wubatswe cyangwa icyerekezo cya stereo, kamera ya ToF itanga ibyiza byinshi. Zitanga amakuru-yimbitse yamakuru, afite igishushanyo cyoroshye, kandi irashobora gukora mubihe bitandukanye. Kamera ya ToF nayo iroroshye kandi irashobora kwinjizwa mubikoresho bito nka terefone zigendanwa, tableti, nibikoresho byambara.

Porogaramu ya kamera ya ToF iratandukanye. Mubyukuri byiyongereye, Kamera ya ToF irashobora kumenya neza ubujyakuzimu bwibintu no kunoza imitekerereze yibintu byashyizwe mubyukuri. Muri robo, bashoboza robot kumenya ibibakikije no kuyobora inzitizi neza. Muri scanne ya 3D, Kamera ya ToF irashobora gufata vuba geometrie yibintu cyangwa ibidukikije kubintu bitandukanye nkukuri kugaragara, gukina, cyangwa gucapa 3D. Zikoreshwa kandi mubikorwa bya biometrike, nko kumenyekana mumaso cyangwa kumenyekanisha ibimenyetso byamaboko.

二、Ibigize igihe cya kamera yindege

Igihe-cyo guhaguruka (ToF) kamerabigizwe nibice byinshi byingenzi bikorana kugirango bishoboke kumva no gupima intera. Ibice byihariye birashobora gutandukana bitewe nigishushanyo nuwabikoze, ariko hano haribintu byibanze mubisanzwe biboneka muri sisitemu ya kamera ya ToF:

Inkomoko y'umucyo:

Kamera ya ToF ikoresha isoko yumucyo kugirango itange ikimenyetso cyumucyo, mubisanzwe muburyo bwurumuri rwa infragre (IR). Inkomoko yumucyo irashobora kuba LED (Diode Yumucyo) cyangwa diode ya laser, ukurikije imiterere ya kamera. Umucyo wasohotse ugenda werekeza kubintu bigaragara.

Amahitamo:

Lens ikusanya urumuri rwerekanwe kandi igashushanya ibidukikije kumashusho yerekana amashusho (indege yibanze). Optique band-pass filter iyinyuza gusa urumuri hamwe nuburebure bwumurambararo nkigice cyo kumurika. Ibi bifasha guhagarika urumuri rutari ngombwa no kugabanya urusaku.

Rukuruzi:

Numutima wa kamera ya TOF. Buri pigiseli ipima igihe urumuri rwafashe kugirango rugende ruva kumurika (laser cyangwa LED) rugana ku kintu hanyuma rugasubira mu ndege yibanze.

Umuzunguruko w'igihe:

Kugirango upime igihe-cyo guhaguruka neza, kamera ikenera igihe cyumuzunguruko. Uyu muzunguruko ugenzura isohoka ryikimenyetso cyumucyo kandi ukamenya igihe bifata kugirango urumuri rugendere mubintu hanyuma usubire kuri kamera. Ihuza ibyuka bihumanya no gutahura kugirango harebwe intera nyayo.

Guhindura:

BamweKamera ya ToFshyiramo tekinike yo guhindura kugirango utezimbere uburinganire n'imbaraga zo gupima intera. Izi kamera zihindura ibimenyetso byerekana urumuri rwasohotse hamwe nuburyo bwihariye cyangwa inshuro. Guhindura bifasha gutandukanya urumuri rwasohotse nandi masoko yumucyo utangiza kandi byongera ubushobozi bwa kamera bwo gutandukanya ibintu bitandukanye mubyerekanwe.

Kubara Ubujyakuzimu Algorithm:

Kugirango uhindure igihe-cyo gupima ibipimo byimbitse, kamera ya ToF ikoresha algorithms ihanitse. Izi algorithm zisesengura amakuru yigihe yakiriwe na fotodetector ikabara intera iri hagati ya kamera nibintu bigaragara. Ubujyakuzimu bwo kubara algorithms akenshi burimo kwishura ibintu nkumuvuduko wo gukwirakwiza urumuri, igihe cyo gusubiza, hamwe n’umucyo utangiza ibidukikije.

Ubujyakuzimu bwamakuru yasohotse:

Iyo ibara ryimbitse rimaze gukorwa, kamera ya ToF itanga amakuru yimbitse. Ibisohoka birashobora gufata ishusho yikarita yimbitse, ingingo igicu, cyangwa 3D igereranya. Ubujyakuzimu bwamakuru bushobora gukoreshwa na porogaramu na sisitemu kugirango bishoboze gukora ibintu bitandukanye nko gukurikirana ibintu, ukuri kwagutse, cyangwa kugendana na robo.

Ni ngombwa kumenya ko ishyirwa mubikorwa ryihariye hamwe nibigize kamera ya ToF bishobora gutandukana mubakora na moderi zitandukanye. Iterambere mu ikoranabuhanga rishobora kumenyekanisha ibintu byongeweho hamwe nogutezimbere kunoza imikorere nubushobozi bwa sisitemu ya kamera ya ToF.

Porogaramu

Porogaramu yimodoka

Kamera-yindegezikoreshwa mubufasha nibikorwa byumutekano kubikorwa byimodoka byateye imbere nkumutekano wabanyamaguru ukora, gutahura precrash hamwe nibisabwa murugo nko hanze yumwanya (OOP).

Imashini yumuntu-imashini no gukina

As kamera-yindegetanga amashusho yintera mugihe nyacyo, biroroshye gukurikirana imigendekere yabantu. Ibi bituma imikoranire mishya nibikoresho byabaguzi nka tereviziyo. Indi ngingo ni ugukoresha ubu bwoko bwa kamera kugirango uhuze nimikino kuri kanseri yimikino ya videwo. Igisekuru cya kabiri cya Kinect sensor ya mbere yashyizwemo na Xbox One konsole yakoresheje igihe-cyo kuguruka kugirango igaragaze amashusho yayo, ituma imikoreshereze yabakoresha bisanzwe hamwe nimikino porogaramu ukoresheje icyerekezo cya mudasobwa hamwe nubuhanga bwo kumenya ibimenyetso.

Kurema na Intel bitanga kandi ubwoko busa bwibimenyetso byerekana igihe-cyo guhaguruka kamera yo gukina, Senz3D ishingiye kuri kamera ya DepthSense 325 ya Softkinetic. Infineon na PMD Technologies ituma kamera ntoya ya 3D yimbitse ya kamera kugirango igenzure ibimenyetso byerekana ibikoresho byabaguzi nka PC zose hamwe na mudasobwa zigendanwa (Picco flexx na Picco monstar kamera).

Gukoresha kamera ya ToF mumikino

Kamera ya terefone

Amaterefone menshi arimo kamera-yindege. Ibi bikoreshwa cyane cyane mukuzamura ireme ryamafoto mugutanga software ya kamera amakuru yerekeye imbere ninyuma. Terefone igendanwa ya mbere yakoresheje ikoranabuhanga ni LG G3, yasohotse mu ntangiriro za 2014.

Gukoresha kamera ya ToF muri terefone zigendanwa

Ibipimo no kureba imashini

Ibindi bikorwa ni imirimo yo gupima, urugero kubuzuza uburebure muri silos. Mu iyerekwa ryimashini zinganda, kamera-yigihe-yindege ifasha gutondeka no kumenya ibintu byakoreshwa na robo, nkibintu binyura kuri convoyeur. Kugenzura inzugi birashobora gutandukanya byoroshye inyamaswa n'abantu bagera kumuryango.

Imashini za robo

Ubundi buryo bwo gukoresha izo kamera ni murwego rwa robo: Imashini za robo zigendanwa zishobora gukora ikarita y’ibidukikije vuba vuba, bikabafasha kwirinda inzitizi cyangwa gukurikira umuntu uyobora. Nka intera yo kubara iroroshye, gusa imbaraga nke zo kubara zikoreshwa. Kubera ko izo kamera zishobora no gukoreshwa mu gupima intera, amakipe yo mu marushanwa ya Robo Yambere Yamenyekanye gukoresha ibikoresho mubikorwa byigenga.
