Dab tsi yog qhov txawv ntawm laser rangefinders thiab ultrasonic rangefinders?
1. Nyob rau hauv cov nqe lus ntawm qhov tseeb, qhov ntsuas qhov tseeb ntawm ultrasonic rangefinders yog nyob rau theem centimeter, thaum lub laser rangefinders yog nyob rau qib millimeter;
2. Nyob rau hauv cov nqe lus ntawm kev ntsuas ntau, qhov ntsuas ntau ntawm ultrasonic rangefinders feem ntau yog nyob rau hauv 80 meters, thaum lub sij hawm ntsuas ntawm handheld laser rangefinders tuaj yeem ncav cuag li 200 meters, thiab qhov ntsuas ntau ntawm laser rangefinders tuaj yeem ncav cuag ntau pua lossis ntau txhiab meters. , txawm tias ntxiv (qhov ntsuas qhov tseeb ntawm laser rangefinders feem ntau yog 1 meter lossis kaum centimeters).
3. Ultrasonic rangefinders yog qhov ua yuam kev. Raws li ultrasonic rangefinders emit suab nthwv dej thiab muaj cov kiv cua-zoo li emission yam ntxwv ntawm lub suab tsis, thaum muaj ntau yam obstacles uas suab tsis dhau los, lub reflected suab tsis muaj ntau, ua rau muaj kev cuam tshuam ntau thiab yooj yim rau kev qhia yuam kev. Txawm li cas los xij, laser rangefinders emit ib tug me me beam ntawm excitation teeb ua ntej rov qab, yog li ntev raws li lub beam yuav dhau mus, yuav luag tsis muaj cuam tshuam.
4. Tus nqi ntawm ultrasonic rangefinders ranges ntawm kaum mus rau pua pua ntawm yuan, thaum tus nqi ntawm laser rangefinders ranges los ntawm pua pua mus rau txhiab los yog kaum txhiab yuan, uas txawv heev nyob ntawm qhov raug thiab nyob deb.
Yog li ntawd, laser rangefinders tau ntev tau siv rau ntau yam kev lag luam hauv peb lub neej niaj hnub, xws li cov neeg tsim khoom sab hauv, cov neeg tshawb nrhiav, cov neeg soj ntsuam, ntsuas hluav taws xob ntawm qhov chaw, cov neeg tua hluav taws, cov phiaj xwm av, cov neeg tsim vaj tsev, cov neeg tsim khoom, cov tsev tsim khoom, cov chaw tsim khoom thiab cov phiaj xwm kev lag luam, cov neeg tsim khoom lag luam. , cov neeg ua haujlwm hauv hav zoov, cov neeg tsim qauv, kev nyab xeeb hluav taws, kev lag luam kis tau tus mob, cov chaw tsheb sib tsoo, cov neeg tsav tsheb crane, kev soj ntsuam thiab kev siv software, Handheld laser rangefinders feem ntau siv hauv kev ntsuas kev ua haujlwm xws li cov ntaub ntawv qauv.
