Lumiispot imapereka chitsimikiziro chapamwamba kwambiri komanso pambuyo pogulitsa, wotsimikiziridwa ndi mayiko, makampani, makamaka, FDA, ndi Chuma. Kuyankha kwa makasitomala ndi ntchito yogulitsa pambuyo.
Lembetsani ku media yathu yothandizira potumiza
Zomvera za AirborneItha kugwirizira mfundo zapamwamba ndi laser ya laser, yomwe imadziwika kuti njira yobwezeretsera mwanzeru, kapena lembani chizindikiro chonse monga momwe zimabwezera, lotchedwa sourform monse, m'malo okhazikika ngati 1 ng. Lidar kwathunthu-fundform imagwiritsidwa ntchito kwambiri ku nkhalango, pomwe kubwereketsa lidoar kuli ndi ntchito yothandiza m'minda yosiyanasiyana. Nkhaniyi makamaka ikufotokoza chivomerezi chobwezeretsedwa ndi kugwiritsidwa ntchito kwake. M'mutu uno, tidzaphimba mitu yayikulu yokhudza lidAr, kuphatikizapo zigawo zake zoyambira, momwe zimagwirira ntchito, momwe imagwirira ntchito, kulondola kwake, machitidwe ake, komanso zomwe zilipo.
Zigawo zikuluzikulu za Lidar
Makina okhala ndi dothi makamaka amagwiritsa ntchito ma lasers okhala pakati pa 500-600 nm, pomwe madera oyendetsa ndege amagwiritsa ntchito ma lasers okhala ndi ma cell a 1000-1600 nm. Kukhazikitsa kwa mpweya wa m'matumbo kumaphatikizaponso kuchuluka kwa laser, chinsalu choyezera mtunda (gawo loyenga), ndi machitidwe owongolera, kuwunikira, komanso kujambula. Zimaphatikizanso dongosolo loyimira padziko lonse lapansi komanso lomwe limakhazikika (imu), nthawi zambiri limaphatikizidwa ndi dongosolo limodzi lodziwika ngati malo ndi malo ozungulira. Dongosolo ili limapereka malo (kutalika kwake, mtunda, komanso kutalika (roll, phula, ndi mutu, ndikuwongolera) deta.
Zovala zomwe laser amachepetsa malowa amathanso kukhala osiyanasiyana, kuphatikizapo zigzag, zofanana, kapena njira zophatikizira. Kuphatikiza kwa Dgps ndi IMU deta ya iMU, limodzi ndi magawo a calciration deta ndi gawo lokwera, limalola dongosolo kuti liziwongolera molondola a Laser Laser. Malangizowa amapatsidwa ma coments (x, y, z) muzogwirizana ndi dziko lonse pogwiritsa ntchito dziko lonse lapansi la dziko la 1984 (wgs84) Datam.
Kodi LidarKuzindikira KwakutaliNchito? Fotokozerani mwanjira yosavuta
Dongosolo la liddar limatulutsa msewu wa osewerera masitepe a chandamale kapena pamwamba.
Mapulogalamu a laser akuwonetsa kuti chandamale ndikubwerera ku Liidar Sensor.
Sensor nthawi yomweyo imayesa nthawi yomwe munthu aliyense amapita ku chandamale ndi kumbuyo.
Kugwiritsa ntchito kuthamanga kwa kuwala ndi nthawi yoyenda, mtunda wopita ku chandamale amawerengedwa.
Kuphatikizidwa ndi malo ndi madera oyambira kuchokera ku GPS ndi iPU shors, magwiridwe enieni a laser amatsimikizika.
Izi zimapangitsa kuti mtambo wandiwewu ukhale mtambo woyimilira kapena chinthu.
Mfundo za Lidar
Makina a Lidar amagwiritsa ntchito mitundu iwiri ya ma lasers: kusungunuka komanso mafunde opitilira. Kutulutsa ma systems amagwira ntchito potumiza njira yochepetsetsa kenako ndikuwunika nthawi yomwe imafunikira kuti mupite ku chandamale ndikubwerera kwa wolandirayo. Kukhazikitsa kwa nthawi yozungulira kumathandiza kudziwa mtunda kupita ku chandamale. Chitsanzo chikuwonetsedwa mu chithunzi chomwe ma ampliplops onse owoneka bwino (a) ndi omwe alandiridwa (AR) amawonetsedwa. Cholinga choyambirira chomwe chimagwiritsidwa ntchito m'dongosolo lino chimakhudza kuthamanga kwa kuwala (c) ndi mtunda wopita ku chandamale (R), kulola kachitidwe kakuwerengera mtunda wochokera pakubwerera.
Kukhazikitsanso kwamphamvu ndi kwathunthu pogwiritsa ntchito lidborne.
Njira yodziwika bwino kwambiri.
Njira yoyezera mu lidar, yomwe imaganizira zonse zojambula ndi mawonekedwe a chandamale, amafotokozedwa mwachidule ndi liDar equation. Incoation iyi imasinthidwa kuchokera ku radar equation ndipo ndizofunikira pakumvetsetsa momwe makina a Lidar amawerengera mtunda. Limafotokoza ubale pakati pa mphamvu ya chizindikiro chopakidwa (PT) ndi mphamvu ya zizindikiro zolandila (pr). Kwenikweni, equation imathandiza kuti ikwaniritse kuchuluka kwa magetsi omwe amatumizidwa kwa wolandirayo atatha kuyang'ana chandamale, zomwe ndizofunikira kuti mudziwe mtunda ndikupanga mamapu olondola. Ubwenziwu umayamba kukhala ndi zinthu ngati siginecha chifukwa cha mtunda ndi zochitika ndi chandamale.
Ntchito za Lidar Kutali
Kuzindikira kwa madera a Lidar kumakhala ndi ntchito zambiri m'magawo osiyanasiyana:
- Mapu a TORRORINE NDI EPROVOVIC KUPANGIRA MALO OGWIRITSA NTCHITO ALIYENSE (DEM).
Mapu a nkhalango ndi masamba mapulani kuti akaphunzire mitengo yazitsulo ndi biomass.
Makina a nyanja ndi m'mphepete mwa goosi wowongolera ndi kusintha kwa nyanja.
Kukonzekera mathithi mu mathira ndi kuyika zithunzi, kuphatikiza nyumba ndi zoyendera maukonde.
Zambiri ndi zojambula zachikhalidwe zamtundu wa mbiri yakale komanso zojambulajambula.
geological ndi migodi ya mapu omwe amapezeka polojekiti ndi kuwunikira.
Galimoto yoyendayenda komanso yosavuta.
Kufufuza kwa mapulaneti, monga kupukusa malo a Mars.
Mukufuna kulumala kwaulere?
