Maziko a lidar
Kuyambira pa 2015 mpaka 2020, dzikolo linapereka njira zingapo zokhudzana, zomwe zimayang'ana pa 'magalimoto olumikiza'ndi'Magalimoto odziyimira pawokha'. Kumayambiriro kwa 2020, mtunduwo udapereka mapulani awiri: luso lanzeru lazakudya ndi njira yochiritsira magetsi ndi kalasi yoyendetsa magalimoto, kuti mumvetsetse bwino malo abwino ndi chitsogozo chamtsogolo cha kuyendetsa moto.
Kukula kwa Yole, kampani yofunsa yapadziko lonse lapansi, lofalitsidwa ndi lipoti la kabuku loti 'Lidoar la Magalimoto Ogwiritsa Ntchito Madioli Pafupi ndi And 202%, Pazaka zopitilira 21 zapitazi.
Kodi lindar yamalo ndi chiyani?
Lidar, kafupi kazindikiritso zakuwala ndi kusinthana, ndi ukadaulo wotsutsa womwe wasintha mafakitale autotive, makamaka m'malo mwa magalimoto odzicepetsa. Imagwira potulutsa ma pulounds owala-nthawi zambiri kuchokera ku laser-kulowera ku chandamale ndikuyeza nthawi yomwe imangobwerera ku sensor. Izi zikugwiritsidwa ntchito popanga mamapu atatu a chilengedwe mozungulira galimoto.
Makina odziwika bwino amadziwika kuti ndi kuthekera kwawo ndi kuthekera kwawo kuzindikira zinthu molondola kwambiri, ndikuwapangitsa chida chofunikira kuyendetsa nokha. Mosiyana ndi makamera omwe amadalira kuunika kowoneka ndipo amatha kulimbana ndi zinthu zina ngati kuwala kochepa kapena kuwala kwa dzuwa, ma seckrar amapereka deta yoyenerera ndi nyengo. Kuphatikiza apo, kuthekera kwa kungoyeza masinja molondola kumalola kuti zinthu zitheke, kukula kwake, komanso kuthamanga kwawo, komwe ndikofunikira poyenda mozungulira ma prenarios.
Tchati chogwiritsa ntchito maziko
Ntchito zogwirira ntchito muzokha:
Lidar (kuwunikira kwaukadaulo komanso kusanja) m'makampani ogulitsa magalimoto kumangoyang'ana poyendetsa kuyendetsa galimoto ndikupititsa patsogolo matekinoloje. Ukadaulo wake wapachibale,Nthawi yakuthawa (taf), imagwira ntchito potulutsa laser ndikuwerengera nthawi yomwe imafunikira kuti zilembedwe izi kuti ziwonekere kuchokera ku zopinga. Njirayi imatulutsa mawu olondola kwambiri a "point's" omwe angapangitse map
Kugwiritsa ntchito ukadaulo wa lidar mu gawo lagalimoto kumakhazikika m'magawo otsatirawa:
Makina oyendetsa pawokha:Lidar ndi amodzi mwa matekinoloje ofunikira kuti akwaniritse kuchuluka kwa zodziyimira pawokha. Imawona chilengedwe mozungulira galimoto, kuphatikizapo magalimoto ena, oyenda pansi, zizindikiro zamisewu, ndi mikhalidwe yamisewu, motero amathandizira njira zoyendetsa molondola komanso molondola.
Makina Othandizira Oyendetsa Magalimoto (Adas):Munthawi ya chithandizo cha driver, lidAr limagwiritsidwa ntchito kukonza zinthu zotetezeka magalimoto, kuphatikizapo kuwongolera kayendedwe kagalimoto, kukhazikika kwadzidzidzi, kulowa kwa anthu oyenda, komanso kupewa cholepheretsa.
Kuyenda kwagalimoto ndikuikidwa:Mapu osinthika a 3D opangidwa ndi Lidar angalimbikitse galimoto kuti ikulondola, makamaka m'matauni omwe madera a GPS ali ochepa.
Kuwunika kwamagalimoto ndi kasamalidwe:LidAr ikhoza kugwiritsidwa ntchito powunikira ndi kusanthula kuyenda kwamagalimoto, zothandizira magalimoto pamsewu pakukonzanso chizindikiro chowunikira ndikuchepetsa kupsinjika.
Kwa akutali akumva, kulumikizana, zokha ndi DTS, etc.
Mukufuna Kufunsira Kwaulere?
Zochitika ku Lidar
1. Lidar miniaturization
Maganizo a makampani opanga mafakitale ali ndi magalimoto kuti magalimoto odziyimira pawokha sayenera kusiyanasiyana kuchokera pamagalimoto wamba kuti athe kusangalala ndi ma aerodynamics ogwira ntchito. Maganizo awa athandiza kuti zinthu zizichitika kwa miniyani miviyar miniar. Zabwino zam'tsogolo ndi za liddar kukhala zazing'ono kuti zikhale zowoneka bwino m'thupi lagalimoto. Izi zikutanthauza kuchepetsa magawo ozungulira kapena ngakhale kuthetsa makina ozungulira, kusuntha komwe kumagwirizana ndi mafakitale pang'onopang'ono kuchokera kumadera omwe ali ndi mafilimu omwe alipo pamavuto okhazikika. Lidar yolimba, yopanda mbali yosuntha, imapereka njira yokhazikika, yodalirika, yothetsera bwino yomwe imakwanira bwino mkati mwa zokongoletsa komanso zothandizira magalimoto amakono.
2. Mankhwala ophatikizidwa
Monga matekinoloje oyendetsa oyang'anira oyenda m'zaka zaposachedwa, opanga ma lidor ena ayamba kugwira ntchito mogwirizana ndi zigawo zamagalimoto zothandizira kukulitsa njira zomwe zimaphatikizira zigawo, monga nyali. Kuphatikiza kumeneku sikumangobisa matsenga, kumapangitsa kuti galimoto ikhale yokongoletsa, komanso imapangitsanso malo abwinowo kuti athetse gawo la lidAr ndi magwiridwe antchito. Kwa magalimoto okwera, njira zina zapamwamba zapamwamba (Abas) ntchito zimafunikira liDar kuti muyang'ane mbali zina m'malo mopereka malingaliro a 360 ° 360 ° 360 ° 360 ° 360 ° 360 °. Komabe, kwa okwera pawokha, monga gawo 4, kulingalira kwa chitetezo kumathandizanso gawo la 360 °. Izi zikuyembekezeka kutsogolera ku magwiridwe antchito ambiri omwe akuwonetsetsa kuti akuwongolera galimoto.
3.Kuchepetsa Mtengo
Monga ukadaulo wokhwima ndi mamba opangira, mtengo wake akuchepa, ndikupangitsa kuti zikhale zotheka kuphatikiza njirazi m'magalimoto ambiri, kuphatikiza mitundu yapamwamba. Democtilization iyi ya ukadaulo wa Lidar ukuyembekezeredwa kuti athandizire kukhazikitsidwa kwa chitetezo champhamvu ndi kudziyendetsa ndege pamsika wamagalimoto.
LidArs pamsika lero ndi 905nm ndi 1550nm / 1535nm Limars, koma malinga ndi mtengo, 905nm ali ndi mwayi.
Misari lid · 95nm lid: Nthawi zambiri, madambo a 905nm dimadar samakwera mtengo chifukwa cha kupezeka kwazinthu zofala za zigawo ndi njira zokhwima zomwe zimagwirizanitsidwa ndi mafunde awa. Ubwino wa mtengowu umapangitsa 905nm liidar wokongola kuti ugwiritse ntchito komwe mitundu yosiyanasiyana ndi chitetezo sichivuta kwenikweni.
1550 / 1535nm lidAr: Zigawo za 1550 / 1535nm Makina, monga ma lasers ndi zowunikira, amakonda kwambiri chifukwa ukadaulo sufala ndipo zigawozo ndizovuta kwambiri. Komabe, ma ribwino potengera chitetezo ndi magwiridwe angalimbikitse mtengo wapamwamba kuti mupeze ntchito zina, makamaka poyendetsa modziyimira pawokha komwe kupezeka kwa nthawi yayitali ndi chitetezo.

4. Chitetezo chowonjezereka komanso cholimbikitsidwa
Tekinoloje yolimbitsa thupi imalimbikitsa kwambiri magwiridwe antchito apamwamba othandiza madalaivala (mabas), ndikupereka magalimoto motsatira mapulogalamu oyendayenda. Kuwongolera kumeneku kotereku monga kuponderezedwa, kupezeka kwa anthu oyenda, komanso kuwongolera kayendedwe kaulendo, kukankhira makampani oyendetsa moyenera.
Nyama
M'magalimoto, masentimita masensara amatulutsa kuwala kumapukuta zinthu ndikubwerera ku sensor. Nthawi yomwe imafunikira kuti ibwerere imagwiritsidwa ntchito kuwerengera mtunda wa zinthu. Chidziwitsochi chimathandiza pangani mapu atsatanetsatane ozungulira mgalimoto.
Makina wamba a lidyar amakhala ndi lasesa kuti atulutse, scanner ndi optanection kuti ajambule kuwala, ndikuwongolera kuti ayang'anire deta ndikupanga mawonekedwe a chilengedwe.
Inde, lidAr amatha kudziwa zinthu zoyenda. Poyesa kusintha kwa zinthu kwakanthawi, lidAr imatha kuwerengetsa liwiro lawo ndi zotupa.
Lidar imaphatikizidwa mu njira zotetezera zamagalimoto kuti ziziwonjezera mawonekedwe monga kusintha kwa kayendedwe kazinthu, kugundana, komanso kuwonekera kwa anthu oyenda pansi popereka miyeso yolondola komanso yodalirika.
Zochitika zomwe zikupitilira muukadaulo zamagetsi zimaphatikizira kuchepetsa kukula kwake ndi mtengo wa madera, kukulitsa mitundu ndi kuthetsa kwapadera, ndikuwaphatikizanso osawoneka bwino m'magalimoto ndi magwiridwe antchito.
[Ulalo:Magawo ofunikira a lidAr laser]
Loser ya 1.5μm yopindika ndi mtundu wa gwero la laser mu madambo aulemu omwe amatulutsa kuwala kwa michere 1.5). Zimatulutsa kuwala kwakanthawi komwe kumagwiritsidwa ntchito kuyeza mtunda polunjika zinthu ndikubwerera ku sensor sensor.
The 1.5μm Studength imagwiritsidwa ntchito chifukwa imapereka bwino pakati pa chitetezero cha maso ndi mawonekedwe amlengalenga. Ma Lasers omwe ali pamtunduwu sakhala ovulaza maso a anthu kuposa momwe amagwirizira pamagetsi ofupikira ndipo amatha kuchita bwino nyengo zosiyanasiyana.
Pomwe 1.5μm Lasers amachita bwino kuposa kuwala kowoneka bwino mu chifunga ndi mvula, kuthekera kwawo kolowera zopinga zakuthambo kulibe malire. Magwiridwe antchito am'mudzi nthawi zambiri amakhala abwino kuposa ofupikirako a Holylethth avers koma osati zothandiza ngati njira zazitali.
Pomwe 1.5μm zopindika zaphikira zimatha kukulira mtengo wa machitidwe a Lidar chifukwa cha ukadaulo wawo wamakono, kupita patsogolo pakupanga ndi chuma chambiri zomwe zikuyembekezeka kuchepetsa ndalama. Zabwino zawo malinga ndi magwiridwe antchito ndi chitetezo zimawoneka kuti zikuwonetsa ndalamazo..
