Laser Rangefinder vs GPS: Kodi Mungasankhe Bwanji Chida Choyezera Choyenera Kwa Inu?

Mu gawo la ukadaulo wamakono woyezera, zida zoyezera za laser ndi zida za GPS ndi zida ziwiri zomwe zimagwiritsidwa ntchito kwambiri. Kaya ndi zoyendera panja, ntchito zomanga, kapena gofu, kuyeza mtunda molondola ndikofunikira. Komabe, ogwiritsa ntchito ambiri amakumana ndi vuto posankha pakati pa chida choyezera cha laser ndi chipangizo cha GPS: ndi chiti chomwe chikugwirizana ndi zosowa zanga? Nkhaniyi ifananiza zonse ziwiri kuchokera ku malingaliro olondola, zochitika zoyenera, kusinthasintha kwa chilengedwe, ndi zina zambiri, kukuthandizani kupanga chisankho chodziwa bwino.

1. Mfundo Zazikulu: Kusiyana Kofunika Pakati pa Matekinoloje Awiriwa

Chojambulira cha laser chimazindikira mtunda mwa kutulutsa kugunda kwa laser ndikuwerengera nthawi yomwe kuwalako kumabweranso pambuyo powunikira kuchokera pa chandamale. Kulondola kwake kumatha kufika pa mulingo wa milimita ndipo ndikwabwino kwambiri poyesa mwachangu komanso molondola mkati mwa mtunda waufupi (nthawi zambiri mamita 100-1500), kutengera mzere wosatsekedwa wa kuwona.

Kumbali inayi, GPS imawerengera malo olumikizirana polandira zizindikiro za satelayiti kenako n’kupeza deta ya mtunda kutengera kusintha kwa ma coordinate amenewa. Ubwino wake ndi wakuti sifunikira mzere wolunjika wowonera cholinga ndipo imatha kuphimba mtunda wapadziko lonse lapansi. Komabe, imakhudzidwa kwambiri ndi mphamvu ya chizindikiro, nyengo, ndi zopinga monga nyumba.

2. Kuyerekeza Magwiridwe Abwino Kwambiri

① Kulondola kwa Muyeso

Zipangizo zofufuzira za laser, pansi pa mikhalidwe yabwino (popanda kusokoneza kwamphamvu kwa kuwala, kuwunikira bwino kwa chandamale), zimatha kupeza kulondola kuyambira ±1 mm mpaka ±1 cm, zomwe zimapangitsa kuti zikhale chisankho chomwe chimakondedwa m'magawo apadera monga kafukufuku wa zomangamanga ndi kapangidwe ka mkati. Mosiyana ndi zimenezi, kulondola kwa zida za GPS zomwe zimagwiritsidwa ntchito ndi ogula nthawi zambiri kumakhala pakati pa 1 mpaka 5 metres, ndipo kumatha kukhudzidwa kwambiri ndi kufalikira kwa satellite ndi kuchedwa kwa chizindikiro. Ngakhale ndi ukadaulo wosiyana wa GPS (DGPS), kulondola sikungatheke kuswa chotchinga cha mita. Chifukwa chake, ngati mukufuna kulondola kwambiri, chipangizo chofufuzira cha laser ndiye chisankho chabwino kwambiri.

② Kusinthasintha kwa Zachilengedwe

Zipangizo zofufuzira za laser zimafuna njira yosatsekedwa yopita ku cholinga, ndipo magwiridwe antchito awo amatha kuchepa m'mikhalidwe monga mvula, chipale chofewa, chifunga, kapena kuwala kowala komwe kungafooketse kuwala kwa laser. Zipangizo za GPS zimagwira ntchito bwino m'malo otseguka, koma zimatha kutaya chizindikiro m'maphompho am'mizinda, m'misewu, kapena m'nkhalango zowirira. Chifukwa chake, pa malo ovuta kapena zochitika zazitali, GPS imapereka kusinthasintha kowonjezereka.

③ Kugwira Ntchito ndi Kukulitsa

Zipangizo zoyezera mtunda, kutalika, ndi ngodya za laser zimadziwika bwino poyesa mtunda, kutalika, ndi ma angles, ndipo mitundu ina yapamwamba imapereka zinthu monga kuwerengera dera/voliyumu ndi kutumiza deta ya Bluetooth. Mosiyana ndi zimenezi, zipangizo za GPS zimapereka ntchito zina monga kukonzekera njira yoyendera, kuyeza kutalika, ndi kutsatira njira zoyendera, zomwe zimapangitsa kuti zikhale zoyenera paulendo wakunja kapena kuyenda pagalimoto. Chifukwa chake, m'zochitika zomwe zili ndi zofunikira zambiri, GPS imapereka phindu lalikulu.

4. Kodi Mungasankhe Bwanji?

Chisankhocho chimadalira kwambiri mayankho a mafunso atatu otsatirawa:

① Kodi mukufuna kulondola kwa milimita?

Ngati inde, sankhani chipangizo choyezera kuwala cha laser.

② Kodi muli ndi malo opitilira 1 km?

Ngati inde, sankhani GPS kapena kuphatikiza GPS ndi laser rangefinder.

③ Kodi mukugwiritsa ntchito m'malo ovuta?

Ngati inde, GPS ndi yodalirika kwambiri, koma onetsetsani kuti chizindikirocho chili chokhazikika.

Ndi kupita patsogolo kwa ukadaulo, machitidwe osakanikirana ophatikiza LiDAR (Laser Detection and Ranging) ndi GPS ayamba kugwiritsidwa ntchito m'magawo monga kuyendetsa pawokha komanso mapu a malo. Zipangizozi zimatha kupeza ma coordinates apadziko lonse lapansi kudzera mu GPS pomwe zikugwiritsa ntchito laser scanning kuti zipange mitundu yolondola kwambiri ya 3D, zomwe zimapangitsa kuti pakhale zabwino ziwiri za "macroscopic positioning + microscopic measure." Kwa ogwiritsa ntchito wamba, kusankha zida zanzeru zomwe zimathandiza mgwirizano wamitundu yambiri kungakhale njira yabwino kwambiri mtsogolo.

Palibe kusiyana kwakukulu pakati pa zida zoyesera za laser ndi zida za GPS. Chofunika kwambiri ndikugwirizana ndi zosowa zanu zazikulu. Ngati mukufuna kuyeza mtunda waufupi molondola komanso moyenera, chida choyesera cha laser ndiye chomwe mungasankhe. Paulendo wautali kapena malo ovuta, zida za GPS ndizoyenera kwambiri. Kwa ogwiritsa ntchito akatswiri, yankho losakanikirana lomwe limaphatikiza zabwino zonse ziwiri lingakhale yankho labwino kwambiri.
