Ko don abubuwan ban sha'awa na waje, ayyukan gini, ko wasan golf, ingantaccen ma'aunin nesa yana da mahimmanci. Duk da haka, masu amfani da yawa suna fuskantar matsala lokacin zabar tsakanin na'urar ganowa ta Laser da na'urar GPS: wanne ne ya dace da buƙatu na? Wannan labarin zai kwatanta duka biyu daga mahangar daidaito, yanayin da ya dace, daidaita yanayin muhalli, da ƙari, yana taimaka muku yanke shawara mai ilimi.
1. Babban Ka'idodin: Mahimman Bambance-bambance Tsakanin Fasaha Biyu
Laser rangefinder yana ƙayyade nisa ta hanyar fitar da bugun bugun laser da ƙididdige lokacin da ake ɗauka don dawowar hasken bayan ya nuna kashe abin da aka sa a gaba. Daidaiton sa zai iya kaiwa matakin millimeter kuma yana da kyau don sauri, daidaitattun ma'auni a cikin gajeren zango (yawanci 100-1500 mita), dangane da layin da ba a rufe ba.
GPS, a gefe guda, yana ƙididdige daidaitawar wuri na yanki ta hanyar karɓar siginar tauraron dan adam sannan kuma samun bayanan nesa dangane da canjin waɗannan haɗin gwiwar. Amfaninsa shine cewa baya buƙatar layin gani kai tsaye zuwa ga manufa kuma yana iya rufe nisan duniya. Koyaya, ƙarfin sigina yana tasiri sosai, yanayin yanayi, da cikas kamar gine-gine.
2. Mahimmin Kwatancen Ayyuka
① Daidaiton Aunawa
Laser rangefinders, a karkashin yanayi mai kyau (babu tsangwama mai ƙarfi, kyakkyawan tunani mai kyau), na iya cimma daidaito tsakanin ± 1 mm zuwa ± 1 cm, yana sanya su zaɓin da aka fi so don fannoni na musamman kamar binciken gine-gine da ƙirar ciki. Sabanin haka, daidaiton na'urorin GPS na mabukaci yawanci jeri ne daga mita 1 zuwa 5, kuma yana iya tasiri sosai ta hanyar rarraba tauraron dan adam da jinkirin sigina. Ko da fasahar GPS ta banbanta (DGPS), da yuwuwar daidaito ya karya shingen matakin mita. Sabili da haka, idan kuna neman matsakaicin daidaito, na'urar kewayawa ta Laser shine mafi kyawun zaɓi.
② Daidaitawar Muhalli
Laser rangefinders suna buƙatar hanyar da ba ta toshewa zuwa ga manufa, kuma aikinsu na iya ƙasƙanta a cikin yanayi kamar ruwan sama, dusar ƙanƙara, hazo, ko haske mai haske wanda zai iya raunana hasken Laser. Na'urorin GPS suna aiki da kyau a wuraren buɗe ido, amma suna iya rasa sigina a cikin kwalayen birni, ramuka, ko dazuzzuka masu yawa. Don haka, don hadaddun ƙasa ko yanayin nisa, GPS yana ba da ƙarin sassauci.
③ Ayyuka da Ƙarfafawa
Laser rangefinders sun ƙware wajen auna nisa, tsayi, da kusurwoyi, tare da wasu ƙididdiga masu tsayi waɗanda ke ba da fasali kamar lissafin yanki/ƙara da watsa bayanan Bluetooth. Sabanin haka, na'urorin GPS suna ba da ƙarin ayyuka kamar tsara hanyar kewayawa, ma'aunin tsayi, da bin diddigin yanayin motsi, yana sa su dace da abubuwan kasada na waje ko kewayawar abin hawa. Don haka, a cikin yanayin yanayi tare da buƙatu da yawa, GPS yana ba da ƙarin ƙima.

4. Yadda za a Zaba?
Shawarar ta dogara da amsoshin tambayoyi uku masu zuwa:
① Kuna buƙatar daidaiton matakin millimeter?
Idan eh, zaɓi na'urar tantancewa ta Laser.
② Shin iyakar ma'aunin ku ya fi kilomita 1?
Idan eh, zaɓi GPS ko haɗin GPS da kewayon Laser.
③ Kuna amfani da shi a cikin hadadden wuri?
Idan eh, GPS ya fi abin dogaro, amma tabbatar da siginar ta tsaya tsayin daka.
Tare da ci gaban fasaha, tsarin matasan da ke haɗa LiDAR (Laser Detection and Ranging) da GPS an fara amfani da su a fagage kamar tuƙi mai cin gashin kansa da taswirar yanki. Waɗannan na'urori na iya samun haɗin kai na duniya ta hanyar GPS yayin amfani da sikanin Laser don samar da ingantattun samfuran 3D, suna samun fa'idodi biyu na "matsayin macroscopic + ma'aunin microscopic." Ga masu amfani gabaɗaya, zabar kayan aikin fasaha waɗanda ke goyan bayan haɗin gwiwar yanayi da yawa na iya zama mafi kyawun zaɓi a nan gaba.
Babu cikakkiyar fifiko tsakanin na'urorin kewayawa na Laser da na'urorin GPS. Makullin shine daidaita ainihin bukatun ku. Idan kuna buƙatar ma'auni daidai kuma ingantaccen ma'auni na gajeriyar nisa, na'urar ganowa ta Laser shine abin da kuke so. Don kewayawa mai nisa ko madaidaicin wuri, na'urorin GPS sun fi dacewa. Ga masu amfani da ƙwararru, ƙayyadaddun mafita wanda ya haɗa fa'idodin duka biyun na iya zama babbar amsa.
