Tej yam yuav tsum tau xav txog thaum yuav ib lub tsom iav raj Rangefinder
1. Kev ntsuas ntau
2. Kev ntsuas qhov tseeb
3. Lub sijhawm siv
Nws tau muab faib ua cov xwm txheej hauv qab no:
a) Tsuas yog yuav tsum ntsuas qhov kev ncua deb li ntawm ob peb meters lossis kaum ob meters,
Thiab thaum qhov tseeb qhov yuav tsum tau tsis siab. Kev pom zoo - "Ultrasonic rangefinder" tuaj yeem siv tau.
Lus Cim - Kev ntsuas cov txiaj ntsig ntawm ultrasonic rangefinder cuam tshuam zoo heev los ntawm ib puag ncig, thiab kev ruaj ntseg thiab kev taw qhia yog qhov phem dua li ntawm lub laser rangefinder, tab sis tus nqi kuj pheej yig, haum rau kev ntsuas sab hauv.
b) Kev ntsuas qhov deb tsis ntev, thiab nws feem ntau yog siv sab hauv tsev nrog cov kev xav tau siab.
Tswv yim - xaiv tau "Hand-held laser rangefinder raws li qhia nyob rau sab laug".
Lus Cim - Lub handheld laser rangefinder yog qhov tsim nyog rau kev siv sab hauv tsev, thiab qhov ntsuas qhov tseeb thiab cov nyhuv zoo heev. Thaum ntsuas sab nraum zoov, vim muaj kev cuam tshuam ntawm lub teeb pom kev sab nraum zoov, qhov tseeb ntawm lub teeb txawb laser rangefinder txo qis.
(Yog hais tias tus neeg siv yuav tsum tau ua kom pom nyob rau hauv ib qho chaw sab nraum zoov, nws raug nquahu kom siv lub laser pom thiab reflector kom ua tiav qhov kev xav tau thiab cov txiaj ntsig.)
Lus Cim: Cov khoom siv hluav taws xob txuas ntxiv siv los ntawm lub laser rangefinder yog nyob rau hauv cov xim liab spectral ntau pom, thiab tej zaum yuav ua rau qhov muag tsis pom kev puas tsuaj thaum saib ncaj qha ntawm lub qhov muag.
c) Qhov ntsuas qhov deb yog qhov ntev, thiab feem ntau yog siv rau sab nraum zoov.
