Muaj ntau ntau hom 3D laser scanning tshuab tam sim no siv, nrog ntau hom thiab ua haujlwm. Raws li kev tshawb fawb sib txawv thiab cov qauv kev ua haujlwm tuaj yeem muab faib ua ntau txoj hauv kev.
Peb-dimensional laser scanning system los ntawm kev ua haujlwm ntawm qhov chaw spatial tuaj yeem muab faib ua plaub pawg hauv qab no:
Airborne laser scanning systems
Cov txheej txheem no yog nqa los ntawm lub dav hlau tsis muaj neeg tsav tsheb lossis cov neeg tsav dav hlau, uas yog tsim los ntawm laser scanner, imaging device, positioning system, davhlau inertial guidance system, computer thiab data collector, recorder, processing software thiab power supply, ntau yam ntawm peb-dimensional feature cov ntaub ntawv nyob rau hauv ib lub sij hawm luv luv.
Hauv av-raws li laser scanning system
Cov txheej txheem no yog ib hom kev ntsuas cov cuab yeej siv laser pulse los ntsuas cov khoom ntsuas, thiab tuaj yeem tau txais cov duab peb sab thiab kev sib koom ua ke ntawm cov khoom hauv av hauv cheeb tsam loj, ceev ceev, siab precision thiab siab ceev. Raws li kev ntsuas hom tseem tuaj yeem muab faib ua ob pawg: lub xov tooj ntawm tes laser scanning system; ib tug ruaj laser scanning system. Lub npe hu ua mobile laser scanning system, yog nyob rau hauv lub tsheb platform, los ntawm lub ntiaj teb no positioning system, inertial navigation system ua ke nrog peb-dimensional laser scanning system. Qhov ruaj khov laser scanning system zoo ib yam li tag nrho cov chaw nres tsheb hauv kev soj ntsuam ib txwm. Lub kaw lus muaj laser scanner thiab tswj qhov system, built-in digital koob yees duab, tom qab ua software thiab lwm yam. Qhov sib txawv nrog rau tag nrho cov chaw nres tsheb yog tias qhov ruaj khov laser scanner sau tsis cais ib qho ntawm peb-dimensional coordinates, tab sis cov ntaub ntawv "point cloud" series. Nws yog tus cwj pwm los ntawm qhov loj scanning ntau, ceev ceev, siab raug thiab kev ua haujlwm zoo hauv kev ua haujlwm.
Handheld Laser Scanners
Hom khoom siv no yog siv los sau 3D cov ntaub ntawv los ntawm cov khoom me me, thiab feem ntau yog siv nrog lub caj npab hloov tau yooj yim. Qhov zoo yog ceev, simplicity thiab raug. Nws yog qhov tsim nyog rau ntau qhov chaw xws li kev tsim khoom thiab kev tsim kho, kev tshawb nrhiav khoom yuam kev, video animation thiab tshuaj.
Laser scanners rau kev siv tshwj xeeb
Xws li cov qhov tsua nyob rau hauv daim ntawv thov ntawm lub laser scanner nyob rau hauv ib qho kev txaus ntshai heev los yog nyuaj mus cuag ib puag ncig, xws li underground mine tunnels, caverns, tunnels thiab lwm yam me me, elongated qhov chaw xws li artificially excavated tunnels, 3D laser scanning tshuab kuj yuav ua tau. ua peb-dimensional scanning.
Peb-dimensional laser scanning system nyob rau hauv raws li lub scanner lub hauv paus ntsiab lus, tab sis kuj muab faib ua peb pawg hauv qab no:
- Kev siv cov tshuab pulse range. Nws qhov ntau tuaj yeem ncav cuag ntau pua meters, lossis txawm ntau txhiab meters.
- Raws li kev ntsuas theem. Feem ntau yog siv rau kev ntsuas ntsuas nruab nrab-nruab nrab, qhov ntsuas qhov ntsuas feem ntau yog nyob rau hauv 100 meters, piv nrog kev siv cov mem tes xws li cov khoom siv scanning, nws qhov tseeb yog qhov siab.
- Optical triangulation txoj cai. Siv optical triangulation txoj cai ntawm cov khoom siv scanning, feem ntau ua hauj lwm nyob deb yog ze, nyob rau hauv ob peb meters los yog kaum ntawm meters, feem ntau yog siv nyob rau hauv engineering ntsuas thiab rov qab qauv thiab lwm yam dej num, muaj peev xwm ua tau siab ntsuas qhov tseeb.
