Kwiyandikisha Mubitangazamakuru Byacu Kubyihuta
Ikoranabuhanga rya LiDAR (Light Detection and Ranging) ryabonye iterambere riturika, cyane cyane kubera uburyo bwagutse. Itanga amakuru-yimibare itatu yerekeye isi, ningirakamaro mugutezimbere amarobo no kuza kwimodoka yigenga. Guhindura kuva muri sisitemu ya LiDAR ihenze cyane kubisubizo bidahenze byizeza kuzana iterambere ryingenzi.
Lidar yumucyo inkomoko yimikorere yibyingenzi aribyo:gukwirakwiza ubushyuhe bwo gupima, imodoka LIDAR, naIkarita ya kure, kanda kugirango wige byinshi niba ubishaka.
Ibipimo byingenzi byerekana imikorere ya LiDAR
Ibikorwa nyamukuru bya LiDAR birimo uburebure bwumurongo wa laser, urwego rwo gutahura, Umwanya wo kureba (FOV), urutonde rwukuri, gukemura impande zose, igipimo cyamanota, umubare wibiti, urwego rwumutekano, ibipimo bisohoka, igipimo cya IP, imbaraga, amashanyarazi, uburyo bwo kohereza lazeri (ubukanishi) / bikomeye-leta), hamwe nigihe cyo kubaho. Ibyiza bya LiDAR bigaragarira muburyo bwagutse bwo kumenya no kumenya neza. Nyamara, imikorere yacyo igabanuka cyane mubihe bikabije cyangwa mubihe byumwotsi, kandi umubare munini wo gukusanya amakuru uza kubiciro bitari bike.
Ngth Uburebure bwa Laser:
Uburebure busanzwe bwa 3D amashusho LiDAR ni 905nm na 1550nm.1550nm yumurambararo wa LiDARIrashobora gukora ku mbaraga zisumba izindi, kuzamura urwego rwo kumenya no kwinjira binyuze mu mvura nigihu. Inyungu yibanze ya 905nm ni iyinjizwa na silicon, bigatuma Photodetector ishingiye kuri silikoni ihendutse kuruta izisabwa kuri 1550nm.
Level Urwego rwumutekano:
Urwego rwumutekano wa LiDAR, cyane cyane niba rwujujeIcyiciro cya 1, Biterwa na laser isohoka imbaraga mugihe cyayo cyo gukora, urebye uburebure bwumurongo nigihe imirasire ya laser.
Urwego rwo Kumenya: Urwego rwa LiDAR rujyanye no kwerekana intego. Kumurika cyane bituma habaho intera ndende, mugihe icyerekezo cyo hasi kigabanya intera.
FOV:
Umwanya wa LiDAR wo kureba urimo impande zombi zitambitse kandi zihagaritse. Sisitemu yo kuzenguruka ya LiDAR mubusanzwe ifite dogere 360 ya horizontal FOV.
Res Igisubizo cya Angular:
Ibi birimo vertical na horizontal imyanzuro. Kugera kumurongo muremure utambitse birasa neza kubera uburyo butwarwa na moteri, akenshi bigera kurwego rwa 0.01. Igisubizo gihagaritse kijyanye nubunini bwa geometrike no gutondekanya ibyuka bisohora, hamwe nibisanzwe hagati ya 0.1 na 1 dogere.
Ate Igipimo cy'amanota:
Umubare w'amanota ya laser yasohotse kumasegonda na sisitemu ya LiDAR muri rusange kuva ku manota icumi kugeza ku bihumbi magana ku isegonda.
◼Umubare w'ibiti:
Multi-beam LiDAR ikoresha ibyuma byinshi byohereza laser bitunganijwe neza, hamwe na moteri ikora moteri ikora ibyuma byinshi byo gusikana. Umubare ukwiye wibiti biterwa nibisabwa byo gutunganya algorithm. Ibiti byinshi bitanga ibisobanuro byuzuye byibidukikije, birashobora kugabanya ibyifuzo bya algorithmic.
◼Ibisohoka Ibisohoka:
Ibi birimo umwanya (3D), umuvuduko (3D), icyerekezo, igihe cyerekana (muri LiDAR zimwe), no kwerekana inzitizi.
Ubuzima Buzima:
Imashini izunguruka LiDAR mubisanzwe imara amasaha ibihumbi, mugihe LiDAR-ikomeye-ishobora kumara amasaha 100.000.
Mode Uburyo bwo gusohora ibyuka:
Gakondo LiDAR ikoresha imashini izunguruka, ikunda kwambara no kurira, igabanya igihe cyo kubaho.Igihugu gikomeyeLiDAR, harimo Flash, MEMS, hamwe na Phase Array ubwoko, itanga igihe kirekire kandi neza.
Uburyo bwo Gusohora Laser:
Sisitemu gakondo ya LIDAR sisitemu ikoresha uburyo bwo guhinduranya imashini, ishobora kuganisha ku kwambara no kubaho igihe gito. Sisitemu ikomeye ya laser radar sisitemu irashobora gushyirwa mubice bitatu byingenzi: Flash, MEMS, hamwe nicyiciro cya array. Flash laser radar itwikiriye umurima wose wo kureba muri pulse imwe mugihe hari isoko yumucyo. Ibikurikira, ikoresha Igihe cyo Guhaguruka (TOF) uburyo bwo kwakira amakuru ajyanye no gutanga ikarita yintego zikikije radar ya laser. MEMS laser radar iroroshye muburyo bworoshye, bisaba gusa urumuri rwa laser hamwe nindorerwamo izunguruka isa na giroscope. Lazeri yerekejwe kuri iyi ndorerwamo izunguruka, igenzura icyerekezo cya laser binyuze mukuzunguruka. Icyiciro cya laser laser radar ikoresha microarray yakozwe na antene yigenga, ikayemerera kohereza imirongo ya radio mubyerekezo byose bidakenewe kuzunguruka. Igenzura gusa igihe cyangwa umurongo wibimenyetso kuri buri antenne kugirango yereke ibimenyetso ahantu runaka.
Ibicuruzwa byacu: 1550nm Yasunitswe na Fibre Laser (LDIAR Umucyo Inkomoko)
Ibintu by'ingenzi:
Imbaraga Zisohoka:Iyi lazeri ifite ingufu zingana na 1.6kW (@ 1550nm, 3ns, 100kHz, 25 ℃), ikongerera imbaraga ibimenyetso kandi ikagura ubushobozi bwurwego, bigatuma iba igikoresho cyingenzi mubikorwa bya laser radar mubidukikije bitandukanye.
Gukoresha amashanyarazi menshi-optique: Kunoza imikorere ningirakamaro mugutezimbere ikoranabuhanga. Iyi fibre fibre fibre ifite imbaraga zidasanzwe zo guhindura amashanyarazi, kugabanya gutakaza ingufu no kwemeza ko ingufu nyinshi zahinduwe mubisubizo byiza bya optique.
Hasi ASE ningaruka zidafite umurongo Urusaku: Ibipimo nyabyo bisaba kugabanya urusaku rutari rukenewe. Inkomoko ya laser ikorana na Amplified Spontaneous Emission (ASE) hamwe n urusaku rutagira umurongo, byemeza amakuru ya lazeri isukuye kandi yuzuye.
Igipimo Cyinshi Cyubushyuhe: Iyi soko ya laser ikora neza mubushyuhe bwa -40 ℃ kugeza 85 ℃ (@shell), ndetse no mubidukikije bisabwa cyane.
Byongeye kandi, Lumispot Tech nayo itanga1550nm 3KW / 8KW / 12KW ya lazeri(nkuko bigaragara ku ishusho hepfo), ibereye LIDAR, ubushakashatsi,ingero,gukwirakwiza ubushyuhe bwo kumva, nibindi byinshi. Kumakuru yihariye yamakuru, urashobora kuvugana nitsinda ryabakozi bacu kurisales@lumispot.cn. Dutanga kandi 1535nm yihariye ya miniature pulsed fibre fibre ikoreshwa muburyo bwo gukora imodoka LIDAR. Kubindi bisobanuro, urashobora gukanda kuri "Ubwiza Bukuru 1535NM MINI YASUBIZE FIBER LASER KURI LIDAR."
