Lub 3D scanner yog ib qho cuab yeej siv thev naus laus zis uas siv los ntes peb - qhov ntev geometry thiab qhov chaw zoo nkauj ntawm cov khoom thiab hloov mus rau hauv cov qauv digital. Nws muaj kev siv dav hauv kev tsim khoom, kev tsim kho, kev kho mob, kev txuag cov cuab yeej cuab tam, thiab kev muaj tiag virtual, muab ntau yam kev tsim kho tshiab thiab kev daws teeb meem thoob plaws ntau yam kev lag luam.
Cov txheej txheem ntsuas ntxov tshaj plaws yog hu rau-raws li, sawv cev los ntawm 3D kev sib koom tes ntsuas tshuab (CMMs). Thaum ua tiav micrometer- qib raug (0.5 hli), lawv qhov loj me, tus nqi siab, thiab tsis muaj peev xwm ntsuas cov khoom muag txwv lawv daim ntawv thov.
Tsis yog-txoj kev ntsuas kev tiv tauj tau tshwm sim, feem ntau muab faib ua ob pawg:
Txoj kev Passive tsis tas yuav muaj lub teeb pom kev tshwj xeeb thiab tso siab rau tag nrho cov teeb pom kev zoo nyob ib puag ncig cov khoom rau kev tshuaj ntsuam. Lawv feem ntau siv cov tshuab binocular, tab sis muaj qhov tseeb tsawg thiab tsuas tuaj yeem luam cov khoom nrog cov duab geometric, ua tsis tau raws li qhov yuav tsum tau ua ntawm ntau qhov chaw.
Cov txheej txheem nquag ua haujlwm tshwj xeeb lub teeb rau ntawm qhov khoom. Laser kab scanning yog ib tug neeg sawv cev technology nrog cov neeg siab, tab sis vim hais tias tsuas yog ib lub teeb beam yuav projected nyob rau hauv ib lub sij hawm, lub scanning ceev yog qeeb. Tsis tas li ntawd, lasers tsis tuaj yeem siv rau hauv qee thaj chaw tshwj xeeb vim tias lawv tuaj yeem ua mob rau cov kab mob muaj sia thiab cov khoom muaj txiaj ntsig.
Ib qho kev siv technology tshiab yog kev teeb pom kev zoo. Cov teeb pom kev zoo kuj yog ib txoj hauv kev ua haujlwm; Nws ua haujlwm ntau lub teeb rays ib txhij los ntawm qhov projection lossis gratings kom ntes ib qho chaw ntawm ib qho khoom. Tsuas yog cov ntaub ntawv los ntawm ob peb qhov chaw yuav tsum tau ua kom tiav qhov scan. Nws qhov zoo tshaj plaws yog:
high scanning ceev thiab programmability.
Lwm lub tshuab yog ua raws li qis- zaus pulse nthwv dej (tsawg- zaus suab nthwv dej), feem ntau yog siv hauv kev ntsuas qib. Raws li ob -dimensional array beamformer transmitting low-frequency pulses, 3D level scanner tau txais cov echoes los ntawm cov khoom hauv silos, chambers, lossis lwm lub thawv. Cov cuab yeej siv cov teeb liab digital processor kuaj thiab txheeb xyuas cov cim tau txais. Los ntawm kev kwv yees lub sij hawm tuaj txog thiab kev taw qhia ntawm echoes, lub processor tsim ib daim duab peb sab -dimensional map ntawm cov khoom nto. Cov duab no tau ua tiav siv txoj kev suav ua tswv los tsim cov duab 3D uas tuaj yeem tso tawm rau ntawm lub vijtsam tej thaj chaw deb. Lub ntsuas qib tuaj yeem txiav txim siab qhov ntim thiab qhov loj ntawm cov khoom, ua kom cov txheej txheem saib xyuas thiab tswj cov khoom muag kom mus txog qib tshiab. Kev txheeb xyuas cov ntaub ntawv raug los ntawm qib ntsuas tuaj yeem txhim kho kev ua haujlwm tau zoo thiab kev tswj hwm kev muaj peev xwm, txo tus nqi siab - thaum muaj xwm txheej ceev, thiab ua kom cov nyiaj tau los.
