Amakuru - ihame ryibanze hamwe no gushyira mubikorwa sisitemu (igihe cya sisitemu)

Iyandikishe ku mbuga nkoranyambaga kubera umwanya wihuse

Uru ruhererekane rugamije guha abasomyi bafite ubujyakuzimu no kumva neza igihe cyindege (TOF). Ibirimo bikubiyemo incamake yuzuye ya sisitemu ya Tof, harimo ibisobanuro birambuye bya tof ya bitaziguye (Yohi) hamwe na Tof (DTOF). Ibi bice bihindura muri sisitemu ibipimo, ibyiza nibibi, hamwe na algorithms zitandukanye. Iyi ngingo irashakisha kandi ibice bitandukanye bya sisitemu ya Tof, nko gusohora amavuta yo gusohora abahinyuye (VCESLS), kwakirwa, guhabwa isssors nka Cis, APD, na Sipm, na Shipcuices, na ascher.

Intangiriro tof (igihe cyo kuguruka)

Amahame shingiro

Tof, guhagarara mugihe cyo kuguruka, nuburyo bukoreshwa mugupima intera mugunjiza umwanya bisaba urumuri kugirango rutere intera runaka muburyo bumwe. Iri hame rikoreshwa cyane cyane mubintu bya optique tof kandi ni muburyo butaziguye. Inzira ikubiyemo isoko yoroheje isohora urumuri rwumucyo, hamwe nigihe cyo gushushanya cyanditswe. Uyu mucyo noneho agaragaza intego, afatwa nuwakira, kandi igihe cyo kwakira kiragaragara. Itandukaniro muri ibi bihe, ryerekanye ko t, rigena intera (D = umuvuduko wumucyo (c) × t / 2).

Ubwoko bwa Tof Sensor

Hariho ubwoko bubiri bwibanze bwa tof sensor: Optique na electromagnetic. SENKICAL TOF SENSORES, zisanzwe, zikoresha urumuri rwinshi, mubisanzwe murwego rwa infrared, kubipimo birenze urugero. Iyi mpingi isohoka kuri sensor, tekereza ku kintu, hanyuma usubire kuri sensor, aho igihe cyingendo gipimwa kandi gikoreshwa mukubara intera. Ibinyuranye, electromagnetic top sensor koresha imiraba ya elecromagnetic, nka radar cyangwa lidar, kugirango upime intera. Bakorera ku ihame risa ariko koresha ubundi buryo butandukanyeGupima intera.

Porogaramu ya Tof Sensor

Toph Sensor ni Vexatile kandi yinjijwe mumirima itandukanye:

Robotics:Ikoreshwa mu kumenya inzitizi no kugenda. Kurugero, robo nka Robba Dorba na Boston imbaraga za Atlas zikoresha kamera zimbitse zo gushushanya ibibakikije no gutegura ingendo.

Sisitemu y'umutekano:Rusange mu bice bya sensor kugirango batange abacengezi, bikurura impuruza, cyangwa gukoresha sisitemu ya kamera.

Inganda zimodoka:Yinjijwe muri sisitemu yo gufasha kugenzura imikino yo guhuza imihindagurikire hamwe no kwirinda kwirinda, bigenda byiganje mumideli nshya yimodoka.

Umwanya w'ubuvuzi: Akoreshwa mu mashusho adateye imbere, nk'intege nke zo guhuza tomografiya (Ukwakira), itanga amashusho yo hejuru.

Amashanyarazi: Ihuriweho muri terefone, ibinini, na mudasobwa zigendanwa kubiranga isura yo mumaso, kwemeza biometric, kwemeza, no kumenya ibimenyetso.

Drone:Ikoreshwa kugirango igende, Kwirinda, no gukemura ibibazo byihariye nibikorwa byindege

Ububiko bwa Chaff

Sisitemu isanzwe ya tof igizwe nibigize byinshi byingenzi kugirango ugere ku gipimo cya kure nkuko byasobanuwe:

· Transmitter (TX):Ibi birimo inkomoko ya laser, cyane cyane aVcsel, umushoferi wumushoferi asic kugirango utware laser, nibice byiza byo kugenzura beam nko guhuza inzira cyangwa ibinyabuzima bitandukanye, na filter.
· Kwakira (RX):Ibi bigizwe n'inzira no muyungurura ku kwakira iherezo, sensor nka CIS, spud, cyangwa sipm bitewe na sisitemu y'ikimenyetso, hamwe na Status yo gutunganya ibimenyetso (ISP) yo gutunganya amakuru menshi muri chip yakira.
·Gucunga Imbaraga:Gucunga ibihamyeIgenzura ryubu kuri VCELS na voltage ndende kubiciro ni ngombwa, bisaba gucunga amashanyarazi.
· SHARISTERI:Ibi birimo software, SDK, OS, no gusaba.

Ubwubatsi bugaragaza uburyo lasery igiti cya laser, gikomoka kuri vcsel kandi gikomoka kubice bya optique, biganyuze mumwanya, bigaragaza ikintu, hanyuma ugasubira uwakira. Igihe cyatinze kubara muriyi nzira gahishura intera cyangwa ubujyakuzimu. Ariko, ubu bubiko ntibupfukirana inzira zubusaku, nkurusaku rwizuba - urusaku rwinshi cyangwa urusaku rwinshi ruva mubitekerezo, byaganiriweho nyuma murukurikirane.

Ibyiciro bya sisitemu ya Tof

Sisitemu ya TOF yashyizwe mubyiciro byintoki zabo: TOF itaziguye (DTOF) hamwe na tof itaziguye (YoO), buri kimwe hamwe nibikoresho bitandukanye hamwe na algorithmic yegereje. Urukurikirane rubanje kwerekana amahame yabo mbere yo kwizirikana mubyerekeranye nibyiza byabo, ibibazo, na sisitemu.

Nubwo ihame risa nkaho ryoroshye rya tof - Gusohora imbibi byoroheje kandi tukabimenya kumara kubara intera - ibinyoma bigoye mugutandukanya urumuri rusubire mu rumuri nyabo. Ibi byakemuwe no gusohora urumuri rwiza bihagije kugirango ugere ku kigereranyo cyo hejuru-urusaku no guhitamo uburebure bukwiye kugirango ugabanye kwivanga. Ubundi buryo nugushinga urumuri rwasohotse kugirango rutandukanye rusubize, rusa na SOS yerekana ibimenyetso.

Urukurikirane rwagereranije rwo kugereranya DTOF kandi ruganira ku itandukaniro ryabo, ibyiza, n'ibibazo birambuye, kandi bikaba byashyizwe mu byiciro bya sisitemu yo gutanga amakuru batanga, uhereye kuri 1d tof kugeza kuri 3d tof.

dtof

TOF itaziguye ipima itaziguye igihe cya Photon. Ikintu cyingenzi, foto yingenzi ya fotolanche diode (spad), numva bihagije kugirango umenye fotosi imwe. DTOF ikoresha igihe cyakosowe na photon kubara (TCSPC) gupima igihe cya Photon Kugera, kubaka Histogramu kugirango ugabanye intera ishoboka ishingiye kumasomo menshi yimyitozo runaka.

Izo

Ikirangantego cya TEF kibara igihe gishingiye ku cyiciro cyicyiciro cyasohotse cyasohotse kandi cyakiriwe, mubisanzwe ukoresheje ibimenyetso bikomeza cyangwa ibimenyetso bya PULSE. YooF irashobora gukoresha ishusho isanzwe yubwubatsi, gupima urumuri rwinshi mugihe.

Inono iragabanijwe cyane muburyo bwa Wave (CW-ATOF) na Pulse Modulation (Pused-Yoof). CW-YooC ipima icyiciro kiri hagati yasohotse kandi yakiriye imiraba ya sinusoidedal, mugihe umuvuduko-Isoko ryubarura icyiciro cyicyiciro cyicyiciro gikoresha ibimenyetso bya kare.
