ILaser Rangefinder vs GPS: Ungasikhethela njani isixhobo sokuMeta esiLungileyo?

Kwinkalo yetekhnoloji yokulinganisa yale mihla, i-laser rangefinders kunye nezixhobo zeGPS zimbini zezona zixhobo zisetyenziswa ngokuqhelekileyo. Nokuba ngoohambo lwangaphandle, iiprojekthi zokwakha, okanye igalufa, umlinganiselo ochanekileyo womgama ubalulekile. Nangona kunjalo, abasebenzisi abaninzi bajongana nengxaki xa bekhetha phakathi koluhlu lwelaser kunye nesixhobo seGPS: yeyiphi eyona ifanele iimfuno zam? Eli nqaku liza kuthelekisa zombini kwiimbono zokuchaneka, iimeko ezisebenzayo, ukuguquguquka kokusingqongileyo, kunye nokunye, kukunceda wenze isigqibo esinolwazi.

1. Imigaqo-siseko enguNdoqo: Umahluko oBalulekileyo phakathi kweeTekhnoloji ezimbini

I-laser rangefinder imisela umgama ngokukhupha i-laser pulse kwaye ibale ixesha elithathayo ukuze ukukhanya kubuye emva kokubonisa ngaphandle kwethagethi. Ukuchaneka kwayo kunokufikelela kwinqanaba le-millimeter kwaye ilungele ukukhawuleza, imilinganiselo echanekileyo ngaphakathi koluhlu olufutshane (ngokuqhelekileyo i-100-1500 yeemitha), kuxhomekeke kumgca ongabonakaliyo wokubona.

I-GPS, kwelinye icala, ibala ulungelelwaniso lwejografi ngokufumana imiqondiso yesathelayithi kwaye emva koko ifumane idatha yomgama ngokusekelwe kutshintsho lwezi lungelelaniso. Inzuzo yayo kukuba ayifuni umgca othe ngqo wokujonga kwindawo ekujoliswe kuyo kwaye inokugubungela imigama yehlabathi. Nangona kunjalo, ichatshazelwa kakhulu ngamandla omqondiso, iimeko zemozulu, kunye nemiqobo efana nezakhiwo.

2. Uthelekiso lweNtsebenzo oluPhambili

① Ukuchaneka koMlinganiso

I-Laser rangefinders, phantsi kweemeko ezifanelekileyo (akukho kuphazamiseka kokukhanya okunamandla, ukubonakaliswa okulungileyo okujoliswe kuyo), banokufikelela ukuchaneka ukusuka kwi-± 1 mm ukuya kwi-± 1 cm, okubenza babe lolona khetho lukhethwayo kwiinkalo ezikhethekileyo ezifana novavanyo lolwakhiwo kunye noyilo lwangaphakathi. Ngokwahlukileyo, ukuchaneka kwezixhobo ze-GPS zodidi lwabathengi ngokuqhelekileyo ziqala ukusuka kwi-1 ukuya kwi-5 yeemitha, kwaye inokuchaphazeleka kakhulu ngokusasazwa kwesathelayithi kunye nokulibaziseka komqondiso. Nangona iteknoloji ye-GPS (i-DGPS) eyahlukileyo, ukuchaneka akunakwenzeka ukuphula umqobo wezinga lemitha. Ke ngoko, ukuba ufuna ukuchaneka okuphezulu, i-laser rangefinder lolona khetho lungcono.

② Ukuziqhelanisa nokusiNgqongileyo

I-Laser rangefinders ifuna indlela engathintelwanga ukuya ekujoliswe kuyo, kwaye ukusebenza kwabo kusenokuthotywa kwiimeko ezinjengemvula, ikhephu, inkungu, okanye ukukhanya okuqaqambileyo okunokwenza buthathaka imbonakalo yelaser. Izixhobo zeGPS zisebenza kakuhle kwiindawo ezivulekileyo, kodwa zinokuphulukana nomqondiso kwimiwonyo yasezidolophini, kwiitonela, okanye kumahlathi ashinyeneyo. Ke ngoko, kwimimandla entsonkothileyo okanye iimeko ezikude, iGPS ibonelela ngokuguquguquka ngakumbi.

③ Ukusebenza kunye noKwandiswa

Ii-Laser rangefinders zisebenza ngokukhethekileyo kumlinganiselo womgama, ubude, kunye nee-engile, ezinemifuziselo ephezulu enikezela ngeempawu ezifana nokubalwa kwendawo/yevolumu kunye nokuhanjiswa kwedatha yeBluetooth. Ngokwahlukileyo koko, izixhobo ze-GPS zibonelela ngemisebenzi eyongezelelweyo efana nokucwangciswa kwendlela yokuhamba, umlinganiselo wokuphakama, kunye nokulandelwa kweetrajectories zokuhamba, ezizenza zilungele ukuhamba ngaphandle okanye ukuhamba kwemoto. Ke ngoko, kwiimeko ezineemfuno ezininzi, iGPS ibonelela ngexabiso elibanzi.

3. Iimeko zesicelo ezicetyiswayo

4. Ukukhetha njani?

Isigqibo ubukhulu becala sixhomekeke kwiimpendulo zale mibuzo mithathu ilandelayo:

① Ngaba ufuna ukuchaneka kwenqanaba lemilimitha?

Ukuba ewe, khetha i-laser rangefinder.

② Ingaba uluhlu lwakho lomlinganiselo lungaphezulu kwe-1 km?

Ukuba ewe, khetha iGPS okanye indibaniselwano yeGPS kunye nelaser rangefinder.

③ Ngaba uyisebenzisa kumhlaba ontsonkothileyo?

Ukuba ewe, i-GPS inokuthenjwa ngakumbi, kodwa qiniseka ukuba isignali ihlala izinzile.

Ngenkqubela phambili yetekhnoloji, iinkqubo ezixubeneyo ezidibanisa i-LiDAR (Ukufunyanwa kweLaser kunye nokuRangi) kunye neGPS ziqalisile ukusetyenziswa kwiinkalo ezifana nokuqhuba ukuzimela kunye nemephu yejografi. Ezi zixhobo zinokufumana ulungelelwaniso lwehlabathi nge-GPS ngelixa zisebenzisa i-laser scanning ukuvelisa iimodeli ezichaneke kakhulu ze-3D, ziphumeza iingenelo ezimbini "zokubekwa kwe-macroscopic + ne-microscopic measurement." Kubasebenzisi ngokubanzi, ukukhetha izixhobo ezikrelekrele ezixhasa ukusebenzisana kweendlela ezininzi kunokuba yeyona ndlela ilungileyo kwixesha elizayo.

Akukho bugqwesileyo bupheleleyo phakathi kwee-laser rangefinders kunye nezixhobo zeGPS. Undoqo kukudibanisa iimfuno zakho eziphambili. Ukuba ufuna imilinganiselo echanekileyo kunye nesebenzayo yomgama omfutshane, i-laser rangefinder yindawo oya kuyo. Ukukhangela umgama omde okanye indawo enzima yokubeka indawo, izixhobo ze-GPS zifanelekile ngakumbi. Kubasebenzisi abaziingcali, isisombululo esidibeneyo esidibanisa izibonelelo zazo zombini zinokuba yimpendulo yokugqibela.
