Kev taw qhia txog kev siv laser rangefinder
Daim ntawv thov ntawm handheld laser rangefinders nyob rau hauv kev ntsuas hauv tsev yeej ib txwm muaj kev txhawj xeeb thiab kev txhawj xeeb rau lub tuam tsev tswj vaj tse. Daim ntawv qhia chaw soj ntsuam hauv tsev yog siv ncaj qha los ua ib qho txuas rau daim ntawv pov thawj ntawm cov tswv cuab thiab muaj kev cai lij choj. Nws tsis yog tsuas yog ncaj qha ntsib cov neeg, tab sis kuj ncaj qha cuam tshuam rau kev lag luam kev txaus siab ntawm cov neeg, yog li kev tswj ntawm kev ntsuas qhov yuam kev hauv vaj tse yog qhov tseem ceeb tshwj xeeb. Raws li yav dhau los tus cwj pwm, kev siv daim kab xev ntsuas los yog steel tapes los ntsuas thaj tsam ntawm lub tsev thiab qhov chaw siv kuj tuaj yeem ua tau raws li qhov yuav tsum tau ua. Txawm li cas los xij, muaj qhov yuam kev tseem ceeb hauv kev ntsuas qhov ntev, ntsuas qhov siab hauv pem teb, thiab nyuaj rau kev ntsuas, nrog rau qhov tsis zoo xws li kev siv zog ua haujlwm siab thiab kev ua haujlwm nyuaj. Nyob rau niaj hnub no kev loj hlob sai ntawm high-tech zej zog, xws li primitive thiab ib txwm ntsuas txoj kev yog kom meej meej tsis nyob rau hauv raws li cov kev cai ntawm niaj hnub cov ntaub ntawv zej zog rau kev ntsuas ceev thiab npaum. Tom qab qhia lub handheld laser rangefinder, ob peb lub hlis ntawm
Hauv kev siv tswv yim, nws feem ntau ntseeg tias cov cuab yeej no tshwj xeeb yog tsim rau kev ntsuas cov vaj tsev complex, cov tsev siab siab, thiab cov tsev nyob deb. Yooj yim rau siv, ntsuas cov ntaub ntawv * * (3mm qhov tseeb), txhim kho kev ua haujlwm zoo (kev ntsuas tsis sib cuag yog ua tau), tso tseg txoj kev ntsuas tsev nrog daim kab xev ntsuas (los yog steel daim kab xev ntsuas), txo cov kev soj ntsuam tsis raug, xyuas kom meej qhov ntsuas qhov ntsuas. qhov tseeb, thiab ua kom qhov ntsuas tau ua kom ntseeg tau ntau dua rau cov tswv tsev. Tau kawg, kuj tseem muaj cov yam ntxwv ntawm cov cuab yeej uas xav tau kev txhim kho sai sai, xws li qhov nyuaj ntawm kev pom cov khoom nyob deb ntawm lub hom phiaj nyob rau hauv lub hnub muaj zog, uas yuav tsum tau siv lub koob yees duab thiab lwm yam khoom siv. Tsis tas li ntawd, calibrating qib npuas thaum lub sij hawm txhua qhov ntsuas yog heev laborious, tab sis nws yuav tsum tau calibrate. Hauv luv luv, handheld laser rangefinders tseem nrov ntawm peb
