Plaub Qhov Kev Siv 3D Kev Tshawb Fawb Hauv Kev Lag Luam Automation
1. Dimension thiab Shape Measurement
Qhov no suav nrog cov yam ntxwv xws li flatness, deg lub kaum sab xis, thiab ntim, haum rau siab -kev tshuaj xyuas cov khoom nyuaj.
2. Kev Tshawb Nrhiav Qhov tob
Ntsuas qhov sib txawv ntawm qhov tob ntawm qhov khoom ntawm qhov chaw (piv txwv li, khawb, dents), nrog qhov tseeb ntawm 5-10 micrometers, haum rau micron-theem kev kuaj pom qhov tsis zoo.
3. Kev xam qhov siab thiab ntim
Los ntawm 3D duab tsom, qhov siab, ntim, thiab lwm yam tsis tuaj yeem suav tau sai, siv rau kev tshuaj xyuas sai hauv kev tsim khoom.
4. Peb -Dimensional Spatial Coordinate Positioning
Tau txais peb - qhov sib koom ua ke ntawm txhua qhov taw qhia ntawm qhov khoom nto los ntawm cov thev naus laus zis xws li teeb pom kev zoo thiab lub teeb pom kev zoo, ua tiav qhov tseeb.
Dab tsi yog 3D Lub Koob Yees Duab thiab Point Clouds?
3D lub koob yees duab tuaj yeem tsis tsuas yog tau txais cov duab kos duab tab sis kuj tau txais cov ntaub ntawv tob ntawm cov khoom yees duab, piv txwv li, peb - qhov chaw thiab qhov ntev. Lawv lub hauv paus ntsiab lus feem ntau yog nyob ntawm peb lub thev naus laus zis: teeb pom kev zoo, lub teeb pom kev zoo, thiab lub sijhawm- ntawm- ya davhlau.
Hauv kev rov qab engineering, txheej txheej ntawm cov ntaub ntawv tau txais los ntawm cov khoom lag luam saum npoo siv cov cuab yeej ntsuas kuj hu ua point cloud. Point huab tau siv peb lub -dimensional coordinate Measuring machine feem ntau muaj cov ntsiab lus me me thiab loj dua ntawm cov ntsiab lus, hu ua sparse point clouds; thaum lub taw tes huab tau siv peb lub -dimensional laser scanner los yog cov duab scanner muaj cov ntsiab lus ntau dua thiab yog cov denser, hu ua cov huab cua ntom ntom.
Ob lub zeem muag daws teeb meem
Structured light: Cov cuab yeej siv thev naus laus zis siv infrared laser ntawm ib lub wavelength tshwj xeeb raws li lub teeb ci, uas tsis pom. Thaum lub laser no tshwj xeeb encoded, nws yog projected mus rau cov khoom. Los ntawm cov txheej txheem ntawm algorithms, peb tuaj yeem txheeb xyuas qhov tsis sib xws ntawm cov qauv rov qab encoded kom tau txais cov ntaub ntawv meej thiab qhov tob ntawm cov khoom. (Qhov tseeb txo qis nrog nce nyob deb)
Binocular stereo vision yog ib qho tseem ceeb ntawm lub tshuab pom kev. Raws li lub hauv paus ntsiab lus ntawm parallax, nws siv cov duab kos kom tau txais ob daim duab ntawm cov khoom ntsuas los ntawm ntau txoj haujlwm. Los ntawm kev xam qhov sib txawv ntawm qhov sib txawv ntawm cov ntsiab lus sib xws hauv cov duab, peb tau txais cov ntaub ntawv geometric ntawm peb -. Binocular vision muab faib ua active thiab passive binocular vision. Active binocular vision nquag emits infrared laser rau ntxiv teeb pom kev zoo, kom nws yuav siv tau txawm hmo ntuj. (Tus nqi qis, tab sis yuav tsum muaj teeb pom kev zoo heev)
