Iyandikishe ku mbuga nkoranyambaga zacu kugira ngo ubone ubutumwa bwihuse
Ikoranabuhanga rya LiDAR (Light Detection and Ranging) ryagize iterambere rikomeye, ahanini bitewe n’ikoreshwa ryaryo mu buryo bwagutse. Ritanga amakuru y’ibice bitatu yerekeye isi, ari ingenzi mu iterambere rya robots no kuzamuka kw’uburyo bwo gutwara ibintu mu buryo bwigenga. Impinduka kuva kuri sisitemu za LiDAR zihenze cyane zijya ku bisubizo bihendutse zisezeranya kuzana iterambere rikomeye.
Imikoreshereze y'urumuri rwa Lidar mu bice by'ingenzi aribyo:gupima ubushyuhe bukwirakwijwe, LIDAR y'imodoka, naikarita yo kureba kure, kanda kugira ngo umenye byinshi niba ubyifuza.
Ibipimo by'ingenzi by'imikorere ya LiDAR
Ibipimo by'ingenzi bya LiDAR birimo ubunini bw'umuraba wa laser, intera yo gutahura, Field of View (FOV), uburyo bwo gupima uburebure, ubushobozi bwo gusuzuma inguni, igipimo cy'ingingo, umubare w'imirasire, urwego rw'umutekano, ibipimo by'umusaruro, IP rating, ingufu, voltage yo gutanga, uburyo bwo gusohora laser (mechanical/solid-state), n'igihe cy'ubuzima. Ibyiza bya LiDAR bigaragara mu buryo bwagutse bwo kumenya no gukoresha neza cyane. Ariko, imikorere yayo igabanuka cyane mu bihe by'ikirere kibi cyane cyangwa mu bihe by'umwotsi, kandi ingano yayo yo gukusanya amakuru menshi itwara amafaranga menshi.
◼ Uburebure bw'Umuraba wa Lazeri:
Ubunini bw'uburebure busanzwe bwa LiDAR ifotora amashusho ya 3D ni 905nm na 1550nm.Utumashini twa LiDAR dufite uburebure bwa 1550nmishobora gukora ku ngufu zo hejuru, yongera ubushobozi bwo kumenya no kwinjira mu mvura n'ibihu. Akamaro k'ibanze ka 905nm ni uko ikoreshwa na silicon, bigatuma ibyuma bipima ikirere bishingiye kuri silicon bihendutse ugereranyije n'ibisabwa kuri 1550nm.
◼ Urwego rw'umutekano:
Urwego rw'umutekano rwa LiDAR, cyane cyane niba yujuje ibisabwaAmahame ngenderwaho yo mu cyiciro cya 1, biterwa n'imbaraga zisohoka za laser mu gihe cyayo cyo gukora, ukurikije uburebure bw'urumuri n'igihe imirasire ya laser imara.
Intera yo Gutahura: Intera ya LiDAR ifitanye isano n'uburyo bwo kugarura urumuri bw'ikintu. Uburyo bwo kugarura urumuri bwinshi butuma habaho intera ndende yo kumenyekanisha, mu gihe uburyo bwo kugarura urumuri buke bugabanya intera.
◼ IBISOBANURO:
Ubuso bwa LiDAR burimo inguni zitambitse n'izihagaze. Sisitemu za LiDAR zizunguruka mu buryo bwa mekanike ubusanzwe zifite FOV itambitse ya dogere 360.
◼ Ubushobozi bw'inguni:
Ibi birimo ubushobozi bwo gupima uhagaze n'ubutambitse. Kugera ku buryo bwo hejuru bwo gupima uhagaze biroroshye bitewe n'uburyo bukoreshwa na moteri, akenshi bugera ku rugero rwa dogere 0.01. Ubuziranenge bwo gupima uhagaze bufitanye isano n'ingano ya geometrike n'imiterere y'ibitanga imirasire, aho ubushobozi bwo gupima uhagaze bukunze kuba hagati ya dogere 0.1 na 1.
◼ Igipimo cy'amanota:
Umubare w'ingingo za laser zisohoka kuri buri segonda na sisitemu ya LiDAR muri rusange uri hagati y'amanota icumi kugeza ku bihumbi amagana kuri buri segonda.
◼Umubare w'imiringoti:
Multi-beam LiDAR ikoresha imirasire myinshi ya laser igororotse, aho moteri izunguruka ikora imirasire myinshi yo gushakisha. Umubare ukwiye w'imirasire uterwa n'ibisabwa na algorithme zo gutunganya. Imirasire myinshi itanga ibisobanuro byuzuye ku bidukikije, bishobora kugabanya ibisabwa kuri algorithme.
◼Ibipimo by'ibisohoka:
Ibi birimo aho ibintu biherereye (3D), umuvuduko (3D), icyerekezo, igihe (muri LiDAR zimwe na zimwe), hamwe n'uburyo inzitizi zigaragara.
◼ Igihe cy'ubuzima:
LiDAR izunguruka mu buryo bwa mekanike isanzwe imara amasaha ibihumbi bike, mu gihe LiDAR ifite imiterere ikomeye ishobora kumara amasaha agera ku 100.000.
◼ Uburyo bwo gusohora imyuka ya laser:
LiDAR gakondo ikoresha imiterere izenguruka mu buryo bwa mekanike, ishobora kwangirika no gucika, ikagabanya igihe cyo kubaho.Imiterere ihamyeLiDAR, harimo ubwoko bwa Flash, MEMS, na Phased Array, itanga kuramba no gukora neza kurushaho.
Uburyo bwo Gusohora Ibyuka Bikoresheje Laser:
Sisitemu za laser LIDAR zisanzwe zikoresha imiterere izenguruka mu buryo bwa mekanike, bishobora gutuma idakora neza kandi ikaba yamara igihe gito. Sisitemu za laser radar zishobora gushyirwa mu byiciro bitatu by'ingenzi: Flash, MEMS, na phased array. Flash laser radar itwikira urwego rwose rw'ishusho mu buryo bumwe igihe cyose hari isoko ry'urumuri. Nyuma yaho, ikoresha Igihe cyo Guhaguruka (Time of Flight) (ToF) uburyo bwo kwakira amakuru ajyanye n'ibyo umuntu ashaka no gukora ikarita y'ibipimo bikikije radar ya laser. Radar ya laser ya MEMS yoroshye mu miterere yayo, isaba gusa urumuri rwa laser n'indorerwamo izenguruka isa na gyroscope. Radar yerekezwa kuri iyi ndorerwamo izenguruka, igenzura icyerekezo cya laser binyuze mu kuzenguruka. Radar ya laser ikoresha microarray ikorwa na antene zigenga, ikemerera kohereza amajwi ya radiyo mu cyerekezo icyo ari cyo cyose nta mpamvu yo kuzenguruka. Igenzura gusa igihe cyangwa urutonde rw'ibimenyetso biva kuri buri antene kugira ngo iyobore ikimenyetso ahantu runaka.
Igicuruzwa cyacu: 1550nm Pulsed Fiber Laser (LDIAR Light Source)
Ibiranga by'ingenzi:
Umusaruro w'ingufu nyinshi:Iyi laser ifite imbaraga nyinshi zigera kuri 1.6kW (@1550nm, 3ns, 100kHz, 25℃), yongera imbaraga z'amajwi no kongera ubushobozi bwo kugera kure, bigatuma iba igikoresho cy'ingenzi mu gukoresha radar ya laser mu bidukikije bitandukanye.
Ingufu nyinshi zo guhindura amashanyarazi n'amatara: Kongera imikorere myiza ni ingenzi cyane mu iterambere ry’ikoranabuhanga. Iyi laser ya fiber ikoresha pulse irangwa n’imikorere myiza cyane mu guhindura amashanyarazi, igabanya gutakaza ingufu no kwemeza ko ingufu nyinshi zihinduka umusaruro w’ingirakamaro w’amashanyarazi.
Urusaku rw'ingaruka za ASE nkeya n'izitari umurongo: Ibipimo nyabyo bisaba kugabanya urusaku rudakenewe. Isoko rya laser rikora neza cyane rifite Amplified Spontaneous Emission (ASE) nkeya cyane hamwe n'urusaku rudashingiye ku murongo, biha icyizere cy'uko amakuru ya radar ya laser asukuye kandi nyayo.
Ingano y'Ubushyuhe Bugari: Iyi sosi ya laser ikora neza mu bushyuhe buri hagati ya -40℃ na 85℃ (@shell), ndetse no mu bihe bikomeye by'ibidukikije.
