Nkhani - mfundo yoyamba ndi kugwiritsa ntchito TOF (nthawi ya ndege)

Lembetsani ku media yathu yothandizira potumiza

Nkhanizi zikufuna kupatsa owerenga ndi kumvetsetsa kwakuya komanso pang'onopang'ono. Zomwe zili zimafotokoza bwino kwambiri za machitidwe a TOF, kuphatikizapo kufotokozera mwatsatanetsatane kwa onse osavomerezeka. Madeti awa amafufuza magawo a dongosolo, zabwino zake ndi zovuta, komanso ma Algorithm osiyanasiyana. Nkhaniyi ikuwunikanso magawo osiyanasiyana a ma tf Systems, monganso zowongoka zoponyera ma lasers (ma vcsels), kupatsa mwayi ndi kulandira ma tayi, mabatani, ndi madera oyendetsa ngati asitor.

Mawu oyambira (nthawi yakuthawa)

Mfundo Zoyambirira

TOF, kuyimirira nthawi yakuuluka, ndi njira yomwe imagwiritsidwa ntchito kuyeza mtunda mwa kuwerengera nthawi yomwe imatenga kuwala kuti isayendetse mtunda wina. Mfundo imeneyi imagwiritsidwa ntchito makamaka mu zojambulajambula zam'maso ndipo ndizowongoka. Njirayi imaphatikizapo gwero lowala lomwe limayatsa kuwala, ndikujambulidwa nthawi yojambulidwa. Kuwala uku kumakulitsa chandamale, kumagwidwa ndi wolandila, ndipo nthawi ya kulandiridwa. Kusiyana kwa nthawi ngati izi, kutanthauza kuti t, kumatsimikizira mtunda (d = kuthamanga kwa kuwala (c) × 2).

Mitundu ya masensa a TOF

Pali mitundu iwiri yoyambira masensa a TOF: Optical ndi Electromagnetic. Ma tony tyf trombors, zomwe ndizofala kwambiri, gwiritsani ntchito ma species, makamaka mu mtundu wa infratir, pamlingo woyimilira. Mapulogalamuwa amatulutsidwa kuchokera ku sensor, kuwunikira chinthu, ndikubwerera ku sensor, komwe nthawi yoyenda imayesedwa ndikugwiritsidwa ntchito kuwerengera mtunda. Mosiyana ndi izi, ma elekitoromagnetic TOF amagwiritsa ntchito mafunde a elekitikiti, monga radar kapena lidar, kuyeza mtunda. Amagwira ntchito mofananamo koma amagwiritsa ntchito sing'anga winaMuyezo Wamtunda.

Ntchito za TOF

Masensa a TOF amakhala ndi chifukwa chophatikizidwa ndi magawo osiyanasiyana:

Robotics:Ntchito zowunikira zosokoneza. Mwachitsanzo, maloboti ngati backba ndi Boston Mphamvu 'Atlas atlas boti a TOF akuya a TOF akupumira malo omwe amakhala ndikukonzekera.

Chitetezo:Wamba mu masensa yoyenda kuti awone olowerera, amayambitsa ma alarm, kapena kuyambitsa magwiridwe antchito.

Makampani Oyendetsa Magalimoto:Yophatikizidwa ndi makina othandizira oyendetsa madalaivala kuti azitha kusintha maulendo apaulendo ndi kuwombana, kukhala wokulirapo m'magalimoto atsopano.

Gawo Lachipatala: Olemba ntchito zosagwirizana ndi kusazindikira, monga mawonedwe owoneka bwino a Totor.

Magetsi amagetsi: Kuphatikizidwa mu mafoni, mapiritsi, ndi ma laptops chifukwa cha mawonekedwe ngati nkhope, kutsimikizika kwa biometric, ndi kuzindikira kwa manja.

Mayero:Yogwiritsidwa ntchito poyenda, kugundana, komanso kuyanjana ndi zinsinsi komanso zokhudza ntchito

Zomanga za TOF

Dongosolo la TOF wamba limakhala ndi zigawo zingapo zazikulu kuti mukwaniritse gawo la mtunda monga tafotokozera:

· "Tx):Izi zimaphatikizapo gwero laulemu, makamaka aVcol, woyendetsa madera oyendetsa kuti ayendetse laser, ndipo owoneka owoneka bwino kuti athetse mandala kapena miyala yosiyanasiyana, ndi zosefera.
· Wolandila (RX):Izi zili ndi magalasi ndi zosefera kumapeto, masensa ngati Cis, Spad, kapena Spad, kapena Spad Signal Proseds (ISP) pokonza kuchuluka kwa chip.
·Kuwongolera mphamvu:Kuyang'anira kholaKuwongolera Kwapano pa VCESLES ndi magetsi kwambiri chifukwa ma spads ndiofunikira, amafuna kuti kasamalidwe ka mphamvu.
· Mapulogalamu Osanjikiza:Izi zimaphatikizapo Firmware, SDK, OS, ndi ntchito wosanjikiza.

Ma kamangidwe amawonetsa momwe mtengo wa laser suva, kuyambira vcsel ndikusinthidwa ndi mitengo yamakhoma, kumayenda pamtunda, kumawunikira chinthu, ndikubwerera kwa wolandirayo. Kuwerengera nthawi sikunawulule izi kapena chidziwitso chakuya. Komabe, mamangidwe awa sadzaphimba njira zowunikira, monga phokoso lowunikira dzuwa kapena phokoso lambiri kuchokera pamawonetseredwe, omwe amakambidwa pambuyo pake mu mndandanda.

Gulu la TOF

Makina a TOF amakhala m'magulu a mtunda wa mtunda wa mtunda: Direct Taf (DTOF) ndi osavomerezeka (Altof), iliyonse yokhala ndi mawonekedwe a algentithmic. Milandu yoyambira imafotokoza mfundo zawo musanaganize kuti ndi zabwino zofananira, zovuta, ndi magawo adongosolo.

Ngakhale kuti mawonekedwe owoneka bwino a TOF - kutulutsa chopopera chopepuka ndikuwona kuti abwereranso kuti awerenge mtunda - zovuta zimakhala ndi kusiyanitsa kuwala kobwerera kuchokera ku kuwala kochokera. Izi zimayankhidwa ndikutulutsa kuwala kokwanira kuti mukwaniritse gawo lalikulu-phokoso ndikusankha magwero oyenera kuti muchepetse kusokonekera kwa chilengedwe. Njira inanso ndikuwunika kuwala kuti ithe kusiya kusiyanso kubwerera, chimodzimodzi ndi shows ndi tochi.

Nkhani zake zimayang'ana kukweza ndi kameneka, ndikukambirana za kusiyana kwawo, zabwino, komanso kuthana ndi zidziwitso za TOF malinga ndi zomwe amapereka, kuyambira 1D tof mpaka 3d.

Mwachindunji TOF amayesa nthawi yayitali ya Photon. Gawo lake lalikulu, tsamba limodzi la Photon Chench Cheide (Spad), limakhala lokwanira kuti mupeze zithunzi zikuluzikulu. DTOF imagwiritsa ntchito nthawi yolumikizana ndi Photon kuwerengera (TCSPC) kuti muyeze nthawi ya Photon, kupanga histogram kuti muchepetse mtunda wopitilira nthawi yayitali.

Thumba laulendo losagwirizana ndi nthawi yopuma kuchokera pa gawo pakati pazomwe zimatulutsa ndikulandila ma fullforms, nthawi zambiri pogwiritsa ntchito zizindikiro zosalekeza kapena kusinthasintha. ITOF ikhoza kugwiritsa ntchito zojambulajambula zowoneka bwino, kuyeza bwino kwambiri pakapita nthawi.

ITOF imagonjeranso mobwerezabwereza kusinthasintha (CW-ITOF) ndi kusinthasintha (kufikiridwa-iyof). Cw-iff imayesa gawo lomwe limasinthira ndikulandila mafunde sawuloisonal, pomwe atulutsidwa-iyo
