Lembetsani ku Social Media Yathu Kuti Mupeze Nkhani Yachangu
Ukadaulo wa LiDAR (Kuzindikira ndi Kuyang'ana Kuwala) wakula kwambiri, makamaka chifukwa cha ntchito zake zosiyanasiyana. Umapereka chidziwitso cha mbali zitatu chokhudza dziko lapansi, chomwe ndi chofunikira kwambiri pakukula kwa ma robotic komanso kubwera kwa kuyendetsa galimoto yodziyimira payokha. Kusintha kuchoka ku makina okwera mtengo a LiDAR kupita ku mayankho otsika mtengo kwambiri kukulonjeza kubweretsa kupita patsogolo kwakukulu.
Kugwiritsa ntchito kwa gwero la kuwala la Lidar pazochitika zazikulu zomwe ndi:muyeso wa kutentha wogawidwa, magalimoto a LIDARndimapu owonera kutali, dinani kuti mudziwe zambiri ngati mukufuna.
Zizindikiro Zofunikira za LiDAR
Magawo akuluakulu a LiDAR ndi monga kutalika kwa nthawi ya laser, kuchuluka kwa kuzindikira, Field of View (FOV), kulondola kwa kusiyana, kutsimikiza kwa angular, kuchuluka kwa mfundo, kuchuluka kwa ma beam, mulingo wa chitetezo, magawo otulutsa, IP rating, mphamvu, magetsi operekera, njira yotulutsira laser (mechanical/solid-state), ndi moyo wake. Ubwino wa LiDAR umawonekera bwino mu kuchuluka kwake kozindikira komanso kulondola kwake. Komabe, magwiridwe ake amachepa kwambiri nyengo ikavuta kapena nyengo yosuta, ndipo kuchuluka kwake kosonkhanitsa deta kumakhala ndi mtengo waukulu.
◼ Kutalika kwa Mafunde a Laser:
Mafunde odziwika bwino a LiDAR yojambula zithunzi za 3D ndi 905nm ndi 1550nm.Masensa a LiDAR a kutalika kwa 1550nmimatha kugwira ntchito pa mphamvu zambiri, zomwe zimapangitsa kuti izindikire bwino komanso ilowe m'malo mwake kudzera mumvula ndi chifunga. Ubwino waukulu wa 905nm ndi kuyamwa kwake ndi silicon, zomwe zimapangitsa kuti ma photodetector okhala ndi silicon akhale otsika mtengo kuposa omwe amafunikira pa 1550nm.
◼ Mulingo wa Chitetezo:
Mulingo wa chitetezo cha LiDAR, makamaka ngati chikukwaniritsaMiyezo ya Kalasi 1, zimadalira mphamvu yotulutsa laser pa nthawi yake yogwira ntchito, poganizira kutalika kwa mafunde ndi nthawi ya kuwala kwa laser.
Kuzindikira Mtundu: Mtundu wa LiDAR umagwirizana ndi kuwunikira kwa cholinga. Kuwunikira kwakukulu kumalola mtunda wautali wozindikira, pomwe kuwunikira kochepa kumafupikitsa mtunduwo.
◼ FOV:
Malo Owonera a LiDAR ali ndi ngodya zopingasa komanso zoyimirira. Makina ozungulira a LiDAR nthawi zambiri amakhala ndi FOV yopingasa ya madigiri 360.
◼ Kukongola kwa Angular:
Izi zikuphatikizapo ma resolution oyima ndi opingasa. Kupeza resolution yopingasa kwambiri kumakhala kosavuta chifukwa cha makina oyendetsedwa ndi injini, nthawi zambiri kufika pamlingo wa madigiri 0.01. Resolution yopingasa imagwirizana ndi kukula ndi kapangidwe ka ma emitter, ndipo ma resolution nthawi zambiri amakhala pakati pa digiri 0.1 mpaka 1.
◼ Chiwerengero cha mfundo:
Chiwerengero cha mfundo za laser zomwe zimatulutsidwa pa sekondi iliyonse ndi dongosolo la LiDAR nthawi zambiri chimakhala kuyambira pa makumi mpaka mazana zikwi za mfundo pa sekondi iliyonse.
◼Chiwerengero cha Matabwa:
LiDAR yokhala ndi ma beam ambiri imagwiritsa ntchito ma laser emitter angapo okonzedwa molunjika, ndipo kuzungulira kwa injini kumapangitsa ma scanning beams angapo. Chiwerengero choyenera cha ma beams chimadalira zofunikira za ma processing algorithms. Ma beams ambiri amapereka kufotokozera kwathunthu kwa chilengedwe, zomwe zingathandize kuchepetsa kufunikira kwa ma algorithm.
◼Magawo Otulutsa:
Izi zikuphatikizapo malo (3D), liwiro (3D), komwe akupita, nthawi yowonera (mu ma LiDAR ena), ndi kuwunikira kwa zopinga.
◼ Nthawi Yokhala ndi Moyo:
LiDAR yozungulira makina nthawi zambiri imatenga maola masauzande angapo, pomwe LiDAR yolimba imatha kukhala maola 100,000.
◼ Njira Yotulutsira Ma Laza:
LiDAR yachikhalidwe imagwiritsa ntchito kapangidwe kozungulira kamakina, komwe kamatha kusweka, zomwe zimapangitsa kuti moyo ukhale wosavuta.Mkhalidwe wolimbaLiDAR, kuphatikizapo mitundu ya Flash, MEMS, ndi Phased Array, imapereka kulimba komanso kugwira ntchito bwino.
Njira Zotulutsira Ma Lazare:
Makina achikhalidwe a laser LIDAR nthawi zambiri amagwiritsa ntchito mapangidwe ozungulira makina, zomwe zingayambitse kuwonongeka ndi moyo wochepa. Makina a radar a laser olimba amatha kugawidwa m'magulu atatu akuluakulu: Flash, MEMS, ndi phased array. Flash laser radar imaphimba gawo lonse la mawonekedwe mu pulse imodzi bola ngati pali gwero la kuwala. Pambuyo pake, imagwiritsa ntchito Nthawi Youluka (ToF) njira yolandirira deta yoyenera ndikupanga mapu a zolinga zozungulira radar ya laser. Radar ya laser ya MEMS ndi yosavuta kapangidwe kake, imafuna kuwala kwa laser kokha ndi galasi lozungulira lofanana ndi gyroscope. Laser imalunjika ku galasi lozungulira ili, lomwe limayang'anira mayendedwe a laser kudzera mu kuzungulira. Radar ya laser yokhazikika imagwiritsa ntchito microarray yopangidwa ndi ma antenna odziyimira pawokha, zomwe zimaloleza kutumiza mafunde a wailesi mbali iliyonse popanda kufunikira kuzungulira. Imangowongolera nthawi kapena mndandanda wa zizindikiro kuchokera ku antenna iliyonse kuti itsogolere chizindikiro kumalo enaake.
Zogulitsa Zathu: 1550nm Pulsed Fiber Laser (LDIAR Light Source)
Zinthu Zofunika Kwambiri:
Mphamvu Yotulutsa Kwambiri:Laser iyi ili ndi mphamvu yotulutsa mphamvu yofika pa 1.6kW (@1550nm, 3ns, 100kHz, 25℃), yomwe imalimbitsa mphamvu ya chizindikiro ndi kutalika kwa mtunda, zomwe zimapangitsa kuti ikhale chida chofunikira kwambiri pakugwiritsa ntchito radar ya laser m'malo osiyanasiyana.
Kugwira Ntchito Mwachangu Kwambiri pa Kutembenuka kwa Magetsi: Kugwira ntchito bwino kwambiri ndikofunikira kwambiri pakupita patsogolo kwa ukadaulo. Laser iyi ya pulsed fiber ili ndi mphamvu yabwino kwambiri yosinthira magetsi, kuchepetsa kuwononga mphamvu ndikuwonetsetsa kuti mphamvu zambiri zimasinthidwa kukhala zotulutsa zowunikira zothandiza.
Phokoso Lochepa la ASE ndi Zotsatira Zosakhala Zam'mbali: Kuyeza molondola kumafuna kuchepetsa phokoso losafunikira. Gwero la laser limagwira ntchito ndi phokoso lochepa kwambiri la Amplified Spontaneous Emission (ASE) komanso phokoso losakhala la mzere, zomwe zimatsimikizira deta yoyera komanso yolondola ya laser radar.
Kutentha Kwambiri Kugwiritsa Ntchito: Gwero la laser ili limagwira ntchito bwino mkati mwa kutentha kwa -40℃ mpaka 85℃ (@shell), ngakhale m'malo ovuta kwambiri.
Kuphatikiza apo, Lumispot Tech imaperekansoMa laser opangidwa ndi pulsed a 1550nm 3KW/8KW/12KW(monga momwe chithunzi chili pansipa chikusonyezera), choyenera LIDAR, malo owonera,kuzungulira,kuzindikira kutentha komwe kumagawidwa, ndi zina zambiri. Kuti mudziwe zambiri za magawo enaake, mutha kulumikizana ndi gulu lathu la akatswiri pasales@lumispot.cnTimaperekanso ma laser apadera a 1535nm miniature pulsed fiber omwe amagwiritsidwa ntchito kwambiri popanga magalimoto a LIDAR. Kuti mudziwe zambiri, dinani "LASER YA CHINTHU CHOPUNGULIRA CHA 1535NM YAPANGIDWA KWAMBIRI YA LIDAR."
