Automotive Lidar inyuma
Kuva muri 2015 kugeza 2020, igihugu cyatanze politiki nyinshi zijyanye, kwibanda kuri 'Ibinyabiziga bifite ubwenge'na'Ibinyabiziga byigenga'. Mu ntangiriro za 2020, ishyanga ryatanze gahunda ebyiri: Ingamba zubwenge zo Guhangayika no Gutwara Iterambere Icyiciro cyo Kwishura, kugirango usobanure umwanya wibikorwa nicyerekezo cyiterambere kizaza cyo gutwara ibinyabiziga byigenga.
Iterambere rya Yole, ikigo cyigisha ku isi hose, cyatangaje raporo y'ubushakashatsi ku isi ijyanye na 'Lidari Porogaramu yo mu mukino ishobora kugera kuri miliyari 5.7 z'amadolari y'Abanyamerika muri 2026, iteganya ko igipimo cy'imisoro cya Amerika cyagutse kugeza ku ya 21% mu myaka itanu iri imbere.
Lidari ni iki?
Lidar, ngufi kubera kumenya urumuri no kuvana, ni tekinoroji y'impinduramatwara yahinduye inganda z'imodoka, cyane cyane mu binyabiziga bigenga. Irakora isohora palses yumucyo - mubisanzwe kuva laser - yerekeza ku ntego no gupima igihe bisaba urumuri rwo gusubira kuri sensor. Aya makuru noneho akoreshwa mugukora amakuru arambuye atatu yibidukikije ibidukikije bikikije imodoka.
Sisitemu ya Lidar irazwi kubijyanye nubushobozi bwabo nubushobozi bwo kumenya ibintu neza, bikabatera igikoresho cyingenzi kubitwara byigenga. Bitandukanye na kamera zishingiye kumucyo ugaragara kandi ushobora guharanira mubihe bimwe nkizuba cyangwa urumuri rwizuba, pulsors yizuba, puss yizuba, gutanga amakuru yizuba, gutanga amakuru yizewe muburyo butandukanye no mubihe. Byongeye kandi, ubushobozi bwa Lidar bwo gupima neza intete yemerera neza kumenya ibintu, ingano yabo, ndetse numuvuduko wabo, ni ngombwa kugirango uyobore ibintu bigoye byo gutwara.
Lidar Akazi Gukora Ihame Ryiza Imbonerahamwe
Porogaramu ya Lidar mu Automation:
Lidar (Gutahura Umucyo no Gutezimbere) Ikoranabuhanga mu nganda z'imodoka ryibanda cyane cyane ku rwego rwo kuzamura umutekano wo gutwara no gutera imbere ikoranabuhanga ryo gutwara abigenga. Ikoranabuhanga ryayo,Igihe cyo kuguruka (tof), ikora mugusohora laser Pulses hanyuma ukabara igihe bisaba kuriyi mpipo zigaragazwa kuva inzitizi. Ubu buryo butanga amakuru yukuri "ingingo, ishobora gushyiraho amakarita atatu-ibidukikije bikikije ibidukikije hamwe na santimeters-urwego rwuzuye rwibitabo.
Gushyira mu bikorwa tekinoroji ya Lidar mu rwego rw'imodoka bigahora mu turere dukurikira:
Sisitemu yo gutwara abantu:Lidar numwe mu ikoranabuhanga ryingenzi ryo kugera ku nzego zigezweho zo gutwara mu bwigenge. Irabona neza ibidukikije ikinyabiziga, harimo n'izindi modoka, abanyamaguru, ibimenyetso byumuhanda, hamwe nuburyo bwo gutwara umuhanda, bityo bifasha sisitemu yo gutwara mu bwigenge mugufata ibyemezo byihuse kandi neza.
Sisitemu yo Gufasha Abashoferi (Adas):Mu rwego rw'abashoferi, Lidar ikoreshwa mu kuzamura ibintu by'umutekano w'imodoka, harimo no kugenzura imikino yo kurwanya imihindagurikire y'ikirere, feri yo kumenya byihutirwa, gutahura abanyamaguru, no kwirinda imirimo y'inzitizi.
Kugenda kw'imodoka no gushyira ahagaragara:Ikarita yo hejuru ya 3d yakozwe na Lidar irashobora kuzamura cyane ibinyabiziga neza, cyane cyane mubidukikije aho ibimenyetso bya GPS bigarukira.
Gukurikirana traffic hamwe n'ubuyobozi:Lidar irashobora gukoreshwa mugukurikirana no gusesengura imihanda ifasha imihanda yo guhitamo kugenzura ibimenyetso no kugabanya ubwinshi.
Kuri kure yunvikana, gushiramo, gufata na Dts, nibindi.

Imigendekere igana kuri lidar
1. Lidar Miniaturisation
Inganda za Automotive Inganda zifata ingamba zigenga zidakwiye gutandukana muburyo busanzwe bwo gukomeza kwinezeza no kwerekana neza Aerodynamics. Iyi myumvire yateye intambwe iganisha kuri sisitemu ya Lidaturings. Ibihe bizaza nibyiza kuba bito bihagije kugirango ushizwemo umubiri wimodoka. Ibi bivuze kugabanya cyangwa no gukuraho ibice byahanikiro, guhinduranya ihuza inganda zigenda ziva mu miterere ya laser igana kuri luder-latidar ibisubizo bikomeye. Ikiligi gikomeye, udafite ibice byimuka, gitanga igisubizo cyoroshye, cyizewe, kandi kirambye gihuye neza mubijyanye nibibazo bya kijyambere nibikorwa byibinyabiziga bigezweho.
2. Ibisubizo bya Lidar
Nkimano yigenga yo gutwara yateye imbere mumyaka yashize, abakora lidar bamwe batangiye gukorana nibice bitanga ibikoresho byo guteza imbere ibisubizo bihuza ibinyabiziga bihuye nibice byimodoka, nkamatara. Iri shyirahamwe ridakora gusa gushimangira gahunda za Lidar, gukomeza kurokorwa ibinyabiziga bifite ibinyabiziga, ariko nanone kugoreka ibikorwa byo guhitamo umuriro wa Lidar wo kureba no gukora. Kumodoka yabagenzi, uburyo bwo gufasha abagenzi (ADAS) imikorere isaba kolsar yibanda ku mfuruka yihariye aho gutanga 360 °. Ariko, kurwego rwo hejuru rwubwigenge, nkurwego rwa 4, ibitekerezo byumutekano bisaba 360 ° ahantu hatambitse. Ibi biteganijwe ko bizaganisha kubiboneza byinshi byemeza ko byuzuye ibinyabiziga.
3.Kugabanya ibiciro
Mugihe tekinoroji ya Lidar ikura hamwe numunzani wuzuye, ibiciro biragabanuka, bigatuma bishoboka gushiramo sisitemu mumodoka nini, harimo moderi ya moderi. Iyi Demokarasi yikoranabuhanga rya Lidar iteganijwe kwihutisha kuba iyemezwa ryumutekano uharanira inyungu ningendo zishinzwe gutwara ibinyabiziga ku isoko ryimodoka.
Umucuzi ku isoko uyu munsi ni 905nm na 1550nm / 1535nm lidars, ariko mubiciro, 905nm ifite akarusho.
· 905NM LIDAR: Mubisanzwe, sisitemu 905nm ntabwo ihenze kubera kuboneka kubigize ibice byinshi hamwe nibikorwa bikuze bifitanye isano nuburebure bwumuyaga. Iki nyungu zihenze zituma 905nm Lidar ikurura porogaramu aho umutekano kandi umutekano wamaso udakomeye.
· 1550 / 1535NM LIDAR: Ibice kuri sisitemu 1550 / 1535nm, nka lazers hamwe nibihano, bikunze kuba bihenze, igice kuko ikoranabuhanga ridakwirakwira kandi ibice biragoye. Ariko, inyungu mubijyanye numutekano nibikorwa birashobora gutsindishiriza ikiguzi cyo hejuru kubisabwa runaka, cyane cyane mubyiciro byigenga aho gutahura hamwe numutekano.
[Ihuza:Soma byinshi kubyerekeye kugereranya hagati ya 905nm na 1550nm / 1535nm lidar]
4. Kongera umutekano no kuzamura Adas
Ikoranabuhanga rya Lidar ritezimbere cyane imikorere ya sisitemu yo gufasha imigambi iharanira inyungu (Adas), itanga ibinyabiziga bifite ubushobozi bwo gutoranya ibidukikije. Uku gusobanuka itezimbere ibintu byumutekano nko kwirinda, gutahura abanyamaguru, no kugenzura imikino ikomeye, gusunika inganda hafi yo kugera ku gutwara amafaranga yigenga.
Ibibazo
Mu modoka, sensors ya Lidar Enmit Shosse yoroheje yikuramo ibintu hanyuma usubire kuri sensor. Igihe ifata kuri pulses kugirango igaruke ikoreshwa mukubara intera kubintu. Aya makuru afasha gukora ikarita irambuye ya 3d yikinyabiziga.
Sisitemu isanzwe yintego zigizwe na laser kugirango urwenya urumuri rwinshi, scaneri na optics kugirango bayobore umucyo ugaragara, hamwe na fotodetector kugirango bafate urumuri rwagaragaye, hamwe nishami ritunganya kugirango usesengura amakuru no gukora 3D byerekana ibidukikije.
Nibyo, lidar irashobora kumenya ibintu byimuka. Mugupima impinduka mumwanya wibintu mugihe, lidar irashobora kubara umuvuduko wabo na traace.
Lidar yinjijwe muri sisitemu yumutekano wimodoka kugirango yongere ibiranga nkibisobanuro bikomeye, kwirinda, no gutahura abanyamaguru mugutanga ibipimo byayo neza kandi byizewe.
Iterambere rihoraho mu ikoranabuhanga rya kiyikomoji ririmo kugabanya ingano n'ibiciro bya sisitemu ya Lidar, byongera intera no gukemura, no kubishyira mu bikorwa byo kutagira aho bihurira no gukora.
A 1.5μm Pusesel Laser ni ubwoko bwa laser inkomoko yakorewe muri sisitemu yintego yimyenda isohora urumuri kumurongo wumuyaga wa micrometero (μm). Itanga paki ngufi yumucyo wa infrared ikoreshwa mugupima intera mugutegura ibintu no gusubira muri socieri.
Uburebure bwa 1.5μm bukoreshwa kuko butanga uburinganire bwiza hagati yumutekano wijisho nubufatanye bwikirere. Abahiga muriyi ngingo yuburebure ntibakunze guteza ibyago byamaso yabantu kuruta abasohoka ku burebure bugufi kandi barashobora gukora neza mubihe bitandukanye.
Mugihe 1.5μm lasers ikora neza kuruta urumuri rugaragara mu gihu n'imvura, ubushobozi bwabo bwo kwinjira inyoni yo mu kirere iracyafite aho igarukira. Imikorere mubihe bibi mubisanzwe nibyiza kuruta uburebure bugufi burahagurutse ariko ntabwo ari byiza nkamahitamo arebire.
Mugihe 1.5μm Pulsers Pubsers irashobora kubanza kongera ikiguzi cya sisitemu ya lidar kubera ikoranabuhanga ryabo rikomeye, iterambere ryibikorwa byubucuruzi, hateganijwe gutera imbere mubukungu bizagabanya amafaranga mugihe. Inyungu zabo mubijyanye n'imikorere n'umutekano bigaragara nko gutsindira ishoramari. Imikorere isumba byose hamwe n'imikorere myiza y'umutekano yatanzwe na fibre ya fibre yatanzwe na fibre.
