I-Laser Rangefinder vs GPS: Ungakukhethela Kanjani Ithuluzi Lokulinganisa Elilungile?

Emkhakheni wobuchwepheshe bokulinganisa besimanje, izitholi ze-laser rangefinder kanye nemishini ye-GPS kungamathuluzi amabili asetshenziswa kakhulu. Kungakhathaliseki ukuthi okokuzidela kwangaphandle, amaphrojekthi wokwakha, noma igalofu, ukukalwa kwebanga okunembile kubalulekile. Nokho, abasebenzisi abaningi babhekana nenkinga lapho bekhetha phakathi kwe-laser rangefinder kanye nedivayisi ye-GPS: iyiphi evumelana kangcono nezidingo zami? Lesi sihloko sizoqhathanisa kokubili ngokwemibono yokunemba, izimo ezisebenzayo, ukuguquguquka kwemvelo, nokunye, okukusiza ukuthi wenze isinqumo unolwazi.

1. Izimiso Eziwumgogodla: Umehluko Obalulekile Phakathi Kobuchwepheshe Obubili

I-laser rangefinder inquma ibanga ngokukhipha i-laser pulse futhi ibale isikhathi esisithathayo ukuze ukukhanya kubuye ngemva kokubonisa ngaphandle kwethagethi. Ukunemba kwayo kungafinyelela izinga lemilimitha futhi ilungele izilinganiso ezisheshayo, ezinembile phakathi kwebanga elifushane (ngokuvamile amamitha angu-100-1500), kuye ngomugqa ongavinjwanga wokubuka.

I-GPS, ngakolunye uhlangothi, ibala izixhumanisi zendawo ngokuthola amasignali esathelayithi bese ithola idatha yebanga ngokusekelwe ekuguqulweni kwalezi zixhumanisi. Inzuzo yayo ukuthi ayidingi umugqa oqondile wokubuka okuhlosiwe futhi ingahlanganisa amabanga omhlaba. Kodwa-ke, kuthintwa kakhulu amandla esignali, izimo zezulu, nezithiyo ezifana nezakhiwo.

2. Ukuqhathanisa Ukusebenza Okubalulekile

① Ukunemba Kwesilinganiso

Izitholi ze-Laser rangefinder, ngaphansi kwezimo ezikahle (akukho ukuphazamiseka kokukhanya okunamandla, ukuboniswa okuhle okuqondiwe), zingafinyelela ukunemba ukusuka ku-±1 mm ukuya ku-±1 cm, okuzenza zibe inketho ekhethwayo yezinkambu ezikhethekile njengezinhlolovo zokwakha nokuklama kwangaphakathi. Ngokuphambene, ukunemba kwamadivayisi e-GPS ebanga lomthengi ngokuvamile asukela kumitha elingu-1 kuye ku-5, futhi kungathinteka kakhulu ngokusatshalaliswa kwesathelayithi nokubambezeleka kwesignali. Ngisho nobuchwepheshe be-GPS obuhlukile (i-DGPS), ukunemba akwenzeki ukuthi kwephule umgoqo wezinga lemitha. Ngakho-ke, uma ufuna ukunemba okuphezulu, i-laser rangefinder iyisinqumo esingcono.

② Ukuzivumelanisa Nemvelo

I-Laser rangefinders idinga indlela engavimbekile eya kulokho okuqondiwe, futhi ukusebenza kwazo kungase kwehle ngaphansi kwezimo ezifana nemvula, iqhwa, inkungu, noma ukukhanya okukhanyayo okungenza buthaka ukukhanya kwelaser. Imishini ye-GPS isebenza kahle ezindaweni ezivulekile, kodwa ingalahlekelwa isignali emihosheni yasemadolobheni, emhubheni, noma emahlathini aminyene. Ngakho-ke, ezindaweni eziyinkimbinkimbi noma izimo ezikude, i-GPS inikeza ukuguquguquka okwengeziwe.

③ Ukusebenza Nokwandiswa

Ama-laser rangefinders asebenza ngokukhethekile ekukaleni ibanga, ubude, nama-engeli, anamamodeli asezingeni eliphezulu anikeza izici ezifana nokubala kwendawo/ivolumu kanye nokudluliswa kwedatha ye-Bluetooth. Ngokuphambene, amadivaysi e-GPS ahlinzeka ngemisebenzi eyengeziwe efana nokuhlela umzila wokuzulazula, ukukalwa kokuphakama kwe-altitude, nokulandelelwa kwama-trajectories okunyakaza, okuwenza afaneleke ukuvakasha kwangaphandle noma ukuzulazula kwemoto. Ngakho-ke, ezimeni ezinezidingo ezinezici eziningi, i-GPS inikeza inani eliphelele.

3. Izimo Zokusebenza Ezinconyiwe

4. Ungakhetha kanjani?

Isinqumo sincike kakhulu ezimpendulweni zemibuzo emithathu elandelayo:

① Ingabe udinga ukunemba kwezinga lemilimitha?

Uma kunjalo, khetha i-laser rangefinder.

② Ingabe ububanzi bakho bokulinganisa bukhulu kuno-1 km?

Uma kunjalo, khetha i-GPS noma inhlanganisela ye-GPS ne-laser rangefinder.

③ Ingabe uyayisebenzisa endaweni eyinkimbinkimbi?

Uma kunjalo, i-GPS ithembeke kakhulu, kodwa qiniseka ukuthi isignali ihlala izinzile.

Ngokuthuthuka kwezobuchwepheshe, amasistimu ayingxube ahlanganisa i-LiDAR (I-Laser Detection and Ranging) kanye ne-GPS isiqalile ukusetshenziswa emikhakheni efana nokushayela okuzenzakalelayo kanye nokubeka imephu yendawo. Lawa madivayisi angathola izixhumanisi zomhlaba wonke nge-GPS kuyilapho esebenzisa ukuskena nge-laser ukuze akhiqize amamodeli anembe kakhulu e-3D, azuze izinzuzo ezimbili “zokuma kwe-macroscopic + nesilinganiso esincane kakhulu.” Kubasebenzisi abajwayelekile, ukukhetha amathuluzi ahlakaniphile asekela ukusebenzisana kwezinhlobo eziningi kungase kube inketho engcono kakhulu esikhathini esizayo.

Akukho ukuphakama okuphelele phakathi kwe-laser rangefinders namadivayisi we-GPS. Okubalulekile wukufanisa izidingo zakho ezibalulekile. Uma udinga izilinganiso ezinembile nezisebenzayo zebanga elifushane, i-laser rangefinder iyindlela yakho yokuya kuyo. Ngokuhamba ibanga elide noma ukuma kwemvelo okuyinkimbinkimbi, amadivaysi e-GPS afaneleka kakhulu. Kubasebenzisi abangochwepheshe, isixazululo esiyingxubevange esihlanganisa izinzuzo zakho kokubili kungaba yimpendulo yokugcina.
