Emkhakheni wezobuchwepheshe besimanjemanje, ama-racefinders we-laser namadivayisi we-GPS ngamathuluzi asetshenziswa kakhulu. Ukuthi ngabe i-adventures yangaphandle, amaphrojekthi wokwakha, noma igalofu, ukulinganiswa kwebanga okunembile kubalulekile. Kodwa-ke, abasebenzisi abaningi babhekana nenkinga lapho bekhetha phakathi kwe-RangeFinder ye-laser nedivaysi ye-GPS: iyiphi evumelana nezidingo zami? Le ndatshana izoqhathanisa zombili kusuka ekuhlolweni kokunemba, izimo ezisebenzayo, ukuzivumelanisa nezimo zemvelo, nokuningi, kukusiza wenze isinqumo esinolwazi.
1. Imigomo Eyinhloko: Umehluko obalulekile phakathi kobuchwepheshe bobabili
I-Laser RangeFinder inquma ibanga ngokukhipha i-laser pulse kanye nokubala isikhathi esidingayo ukuze ukukhanya kubuyiswe ngemuva kokukhombisa ilitshe. Ukunemba kwaso kungafinyelela ezingeni lemilimitha futhi kulungele izilinganiso ezisheshayo, eziqondile ngaphakathi kwebanga elifushane (imvamisa amamitha ayi-100-1500), ngokuya ngomugqa ongahleliwe wokubona.
Ngakolunye uhlangothi, i-GPS, ibala izixhumanisi zendawo yendawo ngokuthola amasiginali we-satellite bese uthola idatha yebanga ngokususelwa ekuguqulweni kwalezi zixhumanisi. Inzuzo yayo ukuthi ayidingi umugqa oqondile wokubona kuthagethi futhi ungamboza amabanga omhlaba. Kodwa-ke, kuthinteka kakhulu ngamandla wesiginali, izimo zezulu, kanye nezingqinamba ezinjengezakhiwo.
2. Ukuqhathanisa kokusebenza okubalulekile
◇ ukulinganisa ukunemba
I-Laser RangeFinders, ngaphansi kwezimo ezifanele (akukho ukuphazamiseka okuqinile okunamandla, ukuboniswa okuqondiwe okuhle), kungafinyelela ukunemba okusukela ku- ± 1 mm kuya ku- Ngokuphambene nalokho, ukunemba kwamadivayisi we-GPS ebangeni labathengi kuvame ukusukela kumamitha ayi-1 kuye kwayi-5, futhi kungathinteka kakhulu ekusakazweni kwe-satellite nokubambezeleka kwesiginali. Noma ngabe ubuchwepheshe obuhlukile be-GPS (DGPS) ubuchwepheshe, ukucacisa akunakwenzeka ukuphula umgoqo weleveli yamamitha. Ngakho-ke, uma ufuna ukunemba okuphezulu, i-Laser RangeFinder iyisinqumo esingcono.
② ukuzivumelanisa nezimo zemvelo
I-Laser RangeFinders idinga indlela engahleliwe ethanjeni, futhi ukusebenza kwawo kungahlehlisa izimo njengemvula, iqhwa, inkungu, noma ukukhanya okukhanyayo okunganciphisa ukuboniswa kwe-laser. Amadivayisi we-GPS enza kahle ezindaweni ezivulekile, kepha angalahlekelwa yisiginali emigodini yasemadolobheni, emgudwini, noma emahlathini aminyene. Ngakho-ke, ngezindawo eziyinkimbinkimbi noma izimo ezinde, i-GPS inikeza ukuguquguquka okwengeziwe.
③ Ukusebenza kanye Nokwenzeka
I-Laser RangeFinders esebenza ngokulinganisa ibanga, ukuphakama, nama-engeli, namamodeli athile aphelele anikela ngezici ezinjengendawo / yokubala kwevolumu kanye nokuhanjiswa kwedatha ye-Bluetooth. Ngokuphambene, amadivaysi e-GPS anikela ngokusebenza okwengeziwe njengokuhlela komzila wokuzulazula, ukulinganiswa kokuhamba, kanye nokulandela umkhondo we-trajectories, kubenza balungele ukufika kwangaphandle noma ukuzulazula kwemoto. Ngakho-ke, kwizimo ezinezidingo ezibumbene, i-GPS inikeza inani eliphelele elibanzi.
3. Kunconywe izimo zohlelo lokusebenza
| Isimo esikhona | Ithuluzi elinconyiwe | Ukubeka into enengqondo |
| Ucwaningo Lwakwakhiwa | I-Laser RangeFinder | Ukunemba okuphezulu nokulinganiswa okusheshayo kobude bamahlaya noma ukuphakama kwaphansi, akukho okuthembela kwisiginali ye-satellite. |
| Indawo yokudlala igalofu | I-Laser Rangefinder + GPS | I-Laser RangeFinder ngokunembile ithola amabanga amabanga amabanga, ngenkathi i-GPS ihlinzeka ngamamephu we-full-course kanye nezithiyo (isib. Izicupho zesihlabathi, izingozi zamanzi). |
| I-Outdoor Hiking / adventure | Idivayisi ye-GPS | Ukuma kwangempela kwesikhathi, ukulandela umkhondo wendlela, kanye nokubuyisa izici zokuzulazula kuqinisekisa ukuphepha nokuvimbela ukulahleka. |
| Ucwaningo Lomhlaba Wezolimo | I-RTK GPS | Usekela isilinganiso esikhulu sendawo yepulazi kanye nokumaka kwemingcele, esebenza kahle kakhulu kune-Laser imishini. |
4. Ungayikhetha Kanjani?
Lesi sinqumo sincike kakhulu ezimpendweni zemibuzo emithathu elandelayo:
① Ngabe udinga ukunemba kwezinga lama-millimeter?
Uma kunjalo, khetha i-Laser RangeFinder.
② Uhla lwakho lokulinganisa lukhulu kune-1 km?
Uma kunjalo, khetha i-GPS noma inhlanganisela ye-GPS ne-Laser RangeFinder.
③ Ngabe uyisebenzisa endaweni eyinkimbinkimbi?
Uma kunjalo, i-GPS ithembeke ngokwengeziwe, kepha qiniseka ukuthi isibonakaliso sihlala sizinzile.
Ngokuthuthuka kwezobuchwepheshe, amasistimu we-hybrid ahlanganisa i-lidar (ukutholwa kwe-laser kanye nokusuka) futhi ama-GPS aqalile ukusetshenziswa ezinkambu njengokushayela okuzimele kanye nemephu yendawo. Lawa madivaysi angathola izixhumanisi zomhlaba nge-GPS ngenkathi usebenzisa ukuskena kwe-laser ukukhiqiza amamodeli anembe kakhulu we-3D, ukufeza izinzuzo ezimbili ze- "Macroscopic positing + ukulinganisa ama-microscopic." Kwabasebenzisi abajwayelekile, ukukhetha amathuluzi ahlakaniphile axhasa ukusebenzisana okuningana kungaba inketho engcono kakhulu ngokuzayo.
Akukho ukuphakama okuphelele phakathi kwama-racefinders we-laser namadivayisi we-GPS. Isihluthulelo ukufanisa izidingo zakho eziyinhloko. Uma udinga ukulinganiswa okunembile futhi okusebenzayo kwebanga lesikhashana, i-Laser RangeFinder ihamba kwakho. Ngokuhamba ibanga elide noma ukuma okunzima kwemvelo, amadivaysi e-GPS afaneleke kakhulu. Kwabasebenzisi abangochwepheshe, isixazululo se-hybrid esihlanganisa izinzuzo zazo zombili ingaba yimpendulo yokugcina.
