Tam sim no, txawm tias nws yog lub ntsej muag robots lossis lub ntsej muag lub koob yees duab, suav nrog txhua tus neeg lub koob yees duab, suav nrog txhua tus neeg tau muaj cov lus nug thaum xaiv Lub koob yees duab 3D Qhov tob: 3D lub koob yees duab 3D ua tau raws li kuv cov kev xav tau? TOF lossis lwm lub koob yees duab 3D?
Yog li, hauv tsab xov xwm no, peb yuav tob dhau los nkag siab txog tus yam ntxwv thiab qhov sib txawv ntawm tof thiab lwm yam 3D tus yees duab 3D yog qhov nrov dua li lwm cov koob yees duab 3D qhov tob tshaj plaws.
Yuav ua li cas yog cov npuaj cua 3D?
Qhov kev nkag siab 3D yog dab tsi? 3D Qhov tob npuaj, tseem hu ua qhov tob hnov lossis 3D npuaj teg los ntawm kev ntsuas lub teeb thiab txhua qhov chaw nyob hauv ib puag ncig kev sib tw nrog lub koob yees duab lossis lub koob yees duab.
Tom qab ntawd, los ntawm kev tshuaj xyuas lub sijhawm lossis cov qauv ntawm cov koob yees duab yog qhov tseem ceeb ntawm qhov chaw ntawm qhov pom ntawm lub sensor .
Nws yog qhov meej meej vim hais tias ntawm no feature ntawm lub luag haujlwm 3D tau ua si lub luag haujlwm ntawm cov neeg muaj kev sib tw ntawm kev ua haujlwm hauv ntau yam ntawm ib qho los ntawm ib qho los ntawm ib qho los ntawm ib qho los ntawm ib qho los ntawm ib qho los ntawm ib qho los ntawm ib qho los ntawm ib qho los ntawm ib qho los ntawm ib qho los ntawm ib qho ntawm.
Lub sij hawm davhlau qhov kev ntsuas yog dab tsi?
Hauv cov lus dhau los, peb tau kawm tias lub sijhawm ntawm lub davhlau yog lub ntsiab lus ntawm kev ntsuas ntawm cov khoom siv txheej txheem .
Lawv feem ntau siv teeb lub teeb xws li vcsels lossis leds uas muaj suab paj nruag nyob ze rau, tsis muaj peev xwm los muab cov ntaub ntawv tob tob ntxiv los muab cov ntaub ntawv tob tob {}}
Lub koob yees duab TOF li cas?
Lub ntsiab cai ua haujlwm ntawm lub koob yees duab TOF yog zoo li lub teeb ci ntsa iab ( scene .
Nws cov txiaj ntsig yog lub sijhawm ua tau zoo tiag tiag thiab muaj peev xwm kom tau txais qhov tob me me; Compact loj thiab kuj siv hluav taws xob tsawg; tsawg txoj kev vam khom rau ntawm lub hom phiaj ntawm lub hom phiaj, thiab nws tuaj yeem ua haujlwm txawm tias ntawm cov chaw tsis muaj zog {}}
Yog xav paub ntxiv txog cov koob yees duab TOF, thov nyeem:Toff Sensor: ua haujlwm lub hauv paus ntsiab lus thiab cov ntsuas kev tivthaiv.
Lub suab ua yeeb yam zoo nkauj tshaj plaws? Cov tsev ua lub Suab Stereo Soj Ntsuam Ua Li Cas?
Stereo Zeem muag ua rau tib neeg qhov muag ua haujlwm, thiab ntau dua) cov duab los ntawm kev sib txawv ntawm cov khoom sib txawv ntawm qhov tsis sib xws Cov ntsiab lus sib xws hauv ob daim duab - uas yog, qhov sib txawv ntawm cov khoom ntawm lub koob yees duab (xws li cov hauv paus ntawm cov koob yees duab (xws li cov ntsiab lus ntsuas duab)}}} ob lub tswv yim xav tau rau qhov no:
- Lub hauv paus:Qhov no yog qhov kev ncua deb ntawm ob lub koob yees duab (txog 50-75 mm - Menyuam kawm ntawv nrug) .
- Kev daws teeb meem:Sib npaug rau qhov tob . Cov pixels ntau dua (tab sis cov kev sib cav sib ceg yog tseem siab dua).
Focal ntev yog sib npaug rau qhov tob ntawm daim teb. Lub pob tawb ntau dua, tab sis kev saib xyuas lub ntsej muag kom pom tseeb ntawm cov thev naus laus zis no .
Qhov zoo ntawm cov thev naus laus zis no yog tias nws yog tus nqi qis, tshwj xeeb tshaj yog thaum tsis muaj qhov teeb pom kev zoo; Tej zaum nws yuav ntes cov duab thiab qhov tob cov ntaub ntawv .
Dab tsi yog teeb tsa lub teeb pom kev? Lub koob yees duab teeb ua haujlwm li cas?
Cov teeb meem lub teeb tshuab hu ua cov qauv teeb, thiab siv cov qauv ntawm cov qauv sib txawv, thiab tom qab ntawd los ntawm qhov ntsuas ntawm cov khoom thiab cov ncauj lus tob ntawm cov khoom .
Cov koob yees duab lub koob yees duab no tseem ua raws li cov qauv txheej txheem los ua kom pom qhov deb ntawm cov khoom siv hloov pauv ntawm cov khoom siv, ntawm 3D daim ntawv qhia ntawm cov khoom yog tsim .
Qhov no tuaj yeem muab qhov tseem ceeb tshaj plaws ntawm kev kaw ntau (feem ntau tsis pub dhau cov ntsiab lus, xws li pom zoo, thiab lwm yam.
Lidar yog dab tsi?
Lidar ua haujlwm nyob rau hauv ib txoj kev zoo sib xws, thiab tseem txiav txim siab deb ntawm lub ntsej muag, ntu) thiab khoom-lub xeev .
Qhov zoo ntawm qhov no yog ntev nrhiav kom deb, txog pua pua ntawm meters; Qhov tseeb tiag tiag yog qhov tseeb, tshwj xeeb yog tsim nyog rau kev xav loj-loj ib puag ncig thiab cov kev qhia txog kev ua kom siab; thiab kev ua tau zoo heev nyob rau hauv muaj zog sab nraum zoov lub teeb .
