Lumispot itanga ubwishingizi bwo hejuru- Kwihuta kwabakiriya no gufata ibyemezo nyuma yo kugurisha.
Iyandikishe ku mbuga nkoranyambaga kubera umwanya wihuse
Indege ya Lidarirashobora gufata ingingo zihariye muri laser pulse, zizwi kugakoreshwa neza, cyangwa wandike ikimenyetso cyuzuye uko gisubiye, cyitwa icyumba cyuzuye, gifite ibifuno nka cm 1). Indirimbo yuzuye lidar ikoreshwa cyane mumashyamba, mugihe ubushishozi bugaruka Lidar ifite porogaramu yagutse muburyo butandukanye. Iyi ngingo cyane iraganira cyane cyane kugaruka lidar nikoreshwa ryayo. Muri iki gice, tuzatwikira ingingo nyinshi zerekeye Lidari, harimo ibice byibanze, uko ikora, sisitemu yabyo, sisitemu, hamwe nibikoresho bihari.
Ibice by'ibanze bya Lidar
Sisitemu-ya Lidari ishingiye kuri Lidar ikoreshwa nuburebure bwamabuye hagati ya 500-600 NM, mugihe sisitemu yo mu kirere ikoresha lasers hamwe nuburebure burebure, kuva kuri 1000-1600 Nm 1000-1600 Nm. Gushiraho Ikirere gisanzwe kirimo scaneri ya laser, igice cyo gupima intera (igice cyururimi), na sisitemu yo kugenzura, gukurikirana, no gufata amajwi, no gufata amajwi, no gufata amajwi, no gufata amajwi, no gufata amajwi, no gufata amajwi. Harimo kandi uburyo butandukanye bwisi (DGPS) hamwe nigice cyo gupima kanortial (IU), akenshi byinjijwe muri sisitemu imwe izwi nka sisitemu na intebe. Sisitemu itanga ahantu nyaburanga (uburebure, uburebure, n'uburebure) no kwerekeza (kuzunguruka, ikibuga, no kuyobora) amakuru.
Ibishushanyo aho lases bipakira akarere karashobora gutandukana, harimo Zigzag, bisa, cyangwa inzira ya elliptique. Ihuriro rya DGPS na IU amakuru, hamwe na calibration yamakuru hamwe nibipimo byo kwiyongera, bituma sisitemu ituma neza ingingo zanyuma zakusanyije. Izi ngingo noneho zihabwa imirongo (x, y, y, z) muri sisitemu yo guhuza na geografiya ukoresheje sisitemu ya geoodetic ya geoodetic yo mu 1984 (WG84) Datum.
Ukuntu UmuridoriKure cyaneImirimo? Sobanura muburyo bworoshye
Sisitemu ya Lidar isohora byihuse palses kugana intego cyangwa hejuru.
Umuseri wa laser ugaragaza intego hanyuma usubire kuri lidsor.
Sensor apima neza igihe ifata kuri buri pulse kugirango igende ku ntego n'inyuma.
Ukoresheje umuvuduko wumucyo nigihe cyurugendo, intera yintego ibarwa.
Hamwe nimyanda hamwe namakuru avuye muri GPS na Imu sensor, ibisobanuro byasobanuwe neza bya laser bimenyekana.
Ibi bivamo igicu cya 3d cyerekana hejuru cyangwa ikintu.
Ihame ry'umubiri rya Lidar
Sisitemu ya Lidar ikoresha ubwoko bubiri bwa lasers: gupangurutse kandi bikomeza. Sisitemu ya Lidar yakazi yohereje urumuri rugufi hanyuma upima igihe bisaba kuri iyi pulse kugirango ujye ku ntego hanyuma usubire ku bakira. Iki gipimo cyigihe cyikigereranyo gifasha kumenya intera yintego. Urugero rwerekanwa mu gishushanyo aho amplitude y'ibimenyetso byoroheje byandujwe (kuri) hamwe n'ikimenyetso cyoroshye cyakiriwe (AR). Ikigereranyo cyibanze gikoreshwa muri iyi sisitemu kirimo umuvuduko wurumuri (c) hamwe nintera ku ntego (r), kwemerera sisitemu kubara intera ishingiye ku gihe bifata urumuri rwo kugaruka.
Kugaruka kugaruka no gupima byuzuye ukoresheje ikirere cyindege.
Sisitemu isanzwe ya lidar.
Inzira yo gupima muri Lidar, isuzuma urutonde rwibintu nibiranga intego, bikubiye muri make kuri lidari isanzwe yibinyoma. Iki kigereranyo gihujwe nikigereranyo cya radar kandi nibyingenzi mu gusobanukirwa uburyo sisitemu ya Lidar ibarira intera. Irasobanura isano iri hagati yububasha bwikimenyetso cyatandujwe (PT) nimbaraga zikimenyetso cyakiriwe (PR). Byibanze, ikigereranyo gifasha kugereranya umubare wumurindi wandujwe usubizwa uwakiriye nyuma yo kwerekana intego, aricyo gikomeye mugena intera no gukora amakarita nyayo. Iyi mibanire izirikana ibintu nkibimenyetso byo kwizirikana kubera intera n'imikoranire hamwe nintego.
Porogaramu ya Lidar Remote Yumva
Lodar Remote Remoge ifite ibyifuzo byinshi mumirima itandukanye:
Ubutaka no gushushanya ikarita yo gukora imyanzuro yo hejuru ya digitale (dems).
amafoto n'ibimera byo kwiga igiti cya karupy na biomass.
gushushanya ikarita yo ku nkombe zo gukurikirana isuri no mu nyanja.
Igenamigambi ry'imijyi n'ibikorwa remezo, harimo inyubako n'imiyoboro yo gutwara abantu.
Ubucukuzi bw'ubucukuzi bw'umurage n'umurage ndangamuco inyandiko z'amateka n'ibihangano.
Ubushakashatsi bwa geologiya no gucukura amabuye y'agaciro yo gushushanya no gukurikirana ibikorwa.
Kugenda mu modoka yigenga no gutahura.
Ubushakashatsi ku mubumbe, nko gushushanya hejuru ya Mars.
