Pankhani yaukadaulo wamakono woyezera, ma laser rangefinder ndi zida za GPS ndi zida ziwiri zomwe zimagwiritsidwa ntchito kwambiri. Kaya ndi zochitika zapanja, zomanga, kapena gofu, kuyeza mtunda wolondola ndikofunikira. Komabe, ogwiritsa ntchito ambiri amakumana ndi vuto posankha pakati pa laser rangefinder ndi chipangizo cha GPS: ndi iti yomwe ikukwaniritsa zosowa zanga? Nkhaniyi ifananiza zonse ziwiri kuchokera pakuwona kulondola, zochitika zomwe zikuyenera kuchitika, kusinthika kwa chilengedwe, ndi zina zambiri, kukuthandizani kupanga chisankho mwanzeru.
1. Mfundo Zazikulu: Kusiyana Kofunikira Pakati pa Technologies Awiri
Laser rangefinder imazindikira mtunda potulutsa kugunda kwa laser ndikuwerengera nthawi yomwe zimatengera kuti kuwala kubwerere pambuyo powunikira. Kulondola kwake kumatha kufika mulingo wa millimeter ndipo ndi yabwino kwa miyeso yofulumira, yolondola mkati mwaufupi (nthawi zambiri 100-1500 metres), kutengera mzere wosatsekeka.
Komano, GPS imawerengetsera malo omwe akugwirizana ndi malo polandira zizindikiro za satelayiti ndikupeza deta yamtunda malinga ndi kusintha kwa ma coordinateswa. Ubwino wake ndikuti sichifunikira kuwongolera kwachindunji kwa chandamale ndipo imatha kuyendera mtunda wapadziko lonse lapansi. Komabe, zimakhudzidwa kwambiri ndi mphamvu zamawu, nyengo, ndi zopinga monga nyumba.
2. Kufananiza Kwamagwiridwe Ofunika Kwambiri
① Mulingo Wolondola
Ma laser rangefinder, pansi pamikhalidwe yabwino (palibe kusokonezedwa kwamphamvu kwa kuwala, kuwunikira kwabwino), amatha kulondola kuyambira ± 1 mm mpaka ± 1 cm, kuwapanga kukhala chisankho chokondedwa pamagawo apadera monga kafukufuku womanga ndi kapangidwe ka mkati. Mosiyana ndi izi, kulondola kwa zida za GPS za ogula nthawi zambiri kumachokera ku 1 mpaka 5 metres, ndipo zimatha kukhudzidwa kwambiri ndi kugawa kwa satellite komanso kuchedwa kwa ma sign. Ngakhale ndiukadaulo wosiyanasiyana wa GPS (DGPS), kulondola sikungathe kuswa chotchinga cha mita. Chifukwa chake, ngati mukufuna kulondola kwambiri, laser rangefinder ndiye chisankho chabwinoko.
② Kusinthasintha Kwachilengedwe
Ma laser rangefinders amafunikira njira yosatsekeka yopita ku chandamale, ndipo magwiridwe ake amatha kutsika ngati mvula, matalala, chifunga, kapena kuwala kowala komwe kungathe kufooketsa kuwala kwa laser. Zipangizo za GPS zimagwira ntchito bwino m'malo otseguka, koma zimatha kutaya mawu m'matawuni, m'ngalande, kapena m'nkhalango zowirira. Chifukwa chake, kumadera ovuta kapena zochitika zakutali, GPS imapereka kusinthasintha.
③ Kugwira ntchito ndi Kutalikirana
Ma laser rangefinder amagwira ntchito poyezera mtunda, kutalika, ndi ngodya, okhala ndi mitundu ina yapamwamba yomwe imapereka zinthu monga kuwerengera kwa madera / voliyumu komanso kutumiza kwa data pa Bluetooth. Mosiyana ndi izi, zida za GPS zimapereka zina zowonjezera monga kukonza njira zoyendera, kuyeza kutalika, komanso kutsatira mayendedwe, zomwe zimapangitsa kuti zikhale zoyenera kuyenda panja kapena kuyendetsa galimoto. Chifukwa chake, muzochitika zokhala ndi zofunikira zambiri, GPS imapereka phindu lokwanira.
3. Zochitika Zovomerezeka Zogwiritsira Ntchito
| Zochitika | Analimbikitsa Chida | Kukambitsirana |
| Kafukufuku wa Malo Omanga | Laser Rangefinder | Kulondola kwambiri komanso kuyeza mwachangu kutalika kwa khoma kapena kutalika kwa pansi, osadalira ma siginecha a satana. |
| Kosi ya Gofu | Laser Rangefinder + GPS | Laser rangefinder imayika mtunda wamtunda, pomwe GPS imapereka mamapu athunthu ndi zidziwitso zopinga (mwachitsanzo, misampha yamchenga, kuopsa kwa madzi). |
| Kuyenda Panja / Ulendo | Chida cha GPS | Kuyimilira munthawi yeniyeni, kutsatira njira, ndi mawonekedwe obwereranso kumatsimikizira chitetezo ndikupewa kutayika. |
| Kafukufuku wa Land Land | RTK GPS | Imathandizira kuyeza kwa minda yayikulu ndikuyika malire, kothandiza kwambiri kuposa zida za laser. |
4. Kodi Mungasankhe Bwanji?
Chisankho chimadalira kwambiri mayankho a mafunso atatu otsatirawa:
① Kodi mukufuna kulondola kwa millimeter?
Ngati inde, sankhani laser rangefinder.
② Kodi muyeso wanu ndi waukulu kuposa 1 km?
Ngati inde, sankhani GPS kapena kuphatikiza kwa GPS ndi laser rangefinder.
③ Kodi mukuigwiritsa ntchito m'malo ovuta?
Ngati inde, GPS ndi yodalirika, koma onetsetsani kuti chizindikirocho chimakhala chokhazikika.
Ndi kupita patsogolo kwaukadaulo, makina osakanizidwa ophatikiza LiDAR (Laser Detection and Ranging) ndi GPS ayamba kugwiritsidwa ntchito m'magawo ngati kuyendetsa pawokha komanso kupanga mapu. Zipangizozi zimatha kupeza zolumikizira zapadziko lonse lapansi kudzera pa GPS pogwiritsa ntchito sikani ya laser kuti apange mitundu yolondola kwambiri ya 3D, ndikupeza maubwino awiri a "macroscopic positioning + miyeso yaying'ono." Kwa ogwiritsa ntchito wamba, kusankha zida zanzeru zomwe zimathandizira kuyanjana kwamitundu yambiri kungakhale njira yabwino kwambiri mtsogolo.
Palibe kupambana kwenikweni pakati pa laser rangefinders ndi zida za GPS. Chofunikira ndikufanana ndi zosowa zanu zazikulu. Ngati mukufuna kuyeza mtunda waufupi molondola komanso moyenera, laser rangefinder ndiye njira yanu. Pakuyenda mtunda wautali kapena malo ovuta, zida za GPS ndizoyenera kwambiri. Kwa ogwiritsa ntchito akatswiri, yankho la haibridi lomwe limaphatikiza zabwino zonse lingakhale yankho lomaliza.
