Tam sim no, tshuab pom kev siv tshuab yog tsuas yog siv nyob rau hauv plaub lub ntsiab lus qhia ntawm qhov chaw, kev ntsuas, kev tshawb nrhiav thiab kev paub hauv Suav teb. Nyob rau hauv cov txheej txheem ntawm kev nrhiav tau cov duab thiab cov duab ua, muaj ntau yam kev nyuaj, uas cuam tshuam ncaj qha rau qhov tseeb ntawm qhov tau txais cov ntaub ntawv tsom xam. Cia peb saib cov kev teeb meem hauv kev tsim cov tshuab tsis pom kev.
Ua ntej, calibration
Calibration yog feem ntau yuav tsum tau nyob rau hauv high-precision ntsuas, uas yog feem ntau muab faib ua optical distortion calibration, projection distortion calibration, khoom thiab duab chaw calibration, thiab lwm yam. Txawm li cas los xij, cov calibration algorithm yog raws li dav hlau calibration, thiab nws yog ib qho nyuaj rau siv calibration. algorithm los daws qhov teeb meem ntawm tsis yog dav hlau calibration. Kuj tseem muaj qee qhov kev ntsuas tshwj xeeb uas tsis siv lub phaj calibration, yog li lub calibration algorithm yuav tsis daws txhua yam teeb meem.
Qhov thib ob, qhov ntsuas qhov tseeb ntawm software
Kev ntsuas qhov tseeb yog feem ntau 1/2-1/4 pixels, vim tias qhov ntsuas software raug tsawg dhau, cov ntsiab lus tsawg dua cov ntsiab lus tau muab rho tawm los ntawm daim duab.
Los ntawm tsib qhov teeb meem saum toj no, nws tuaj yeem pom tau tias yuav muaj ntau yam cuam tshuam hauv kev tsim lub tshuab tsis pom kev, yog li peb yuav tsum tau ua kom zoo dua qub thiab txhim kho thev naus laus zis kom tsis txhob muaj cov teeb meem uas tsis tuaj yeem, tab sis kuj ntseeg tias kev tsim kho thev naus laus zis, ntau yam teeb meem. daws tsis tau.
Thib peb, qhov ceev ntawm kev txav ntawm cov khoom
Nyob rau hauv tus txheej txheem ntawm kev nrhiav tau cov duab, cov duab qhov muag plooj qhov tseeb nyob ntawm cov khoom txav ceev thiab lub koob yees duab raug lub sij hawm, yog li cov khoom nrawm nrawm yuav ua rau cov duab plooj, ntxiv rau, lwm yam khoom siv (lub koob yees duab kev lag luam, cov khoom siv lo ntsiab muag, lub teeb ci, thiab lwm yam) kuj yuav cuam tshuam ncaj qha rau kev tshawb pom.
Plaub, qhov sib xws ntawm qhov chaw ua haujlwm
Qhov tsis sib xws ntawm qhov chaw ua haujlwm yog qhov tseem ceeb tshwj xeeb ntawm kev txhawj xeeb uas ua rau kev ntsuas ntsuas. Txawm hais tias nws yog kev tshawb nrhiav hauv online lossis offline nrhiav pom ntawm cov kab ntau lawm, lub tshuab tsis pom kev yuav tsum xyuas kom meej tias txoj haujlwm tau txais los ntawm cov khoom lag luam yog tib txoj haujlwm thaum tau txais cov ntaub ntawv duab ntawm cov khoom, txwv tsis pub qhov chaw yuav tsis raug, txoj hauj lwm ntawm cov khoom. Kev ntsuas cov cuab yeej yuav tsis raug, ua rau qhov sib txawv ntawm qhov ntsuas ntsuas, thiab nws nyuaj rau kev tswj cov khoom tsim nyog.
Thib tsib, kev ruaj ntseg ntawm teeb pom kev zoo
Hauv kev siv tshuab pom kev, teeb pom kev ruaj ntseg cuam tshuam qhov tseeb ntawm kev ntsuas feem ntau, vim tias ntev npaum li qhov teeb pom kev hloov pauv me ntsis, qhov ntsuas ntsuas yuav yog 1 txog 2 pixels tsis raug. Qhov laj thawj tseem ceeb yog qhov tsis ruaj khov ntawm lub teeb pom kev zoo yuav cuam tshuam qhov kev hloov ntawm ntug txoj hauj lwm ntawm cov duab tau, yog li lub zog ntawm lub teeb pom kev zoo yuav tsum raug tshem tawm kom tsawg kawg nkaus hauv kev tsim lub tshuab tsis pom kev, thiab kev ruaj ntseg ntawm kev txhawb nqa lub teeb ci. yuav tsum tau xyuas.
Los ntawm cov saum toj no, nws tsis yog qhov nyuaj rau pom tias yuav muaj ntau yam cuam tshuam rau kev tsim lub tshuab tsis pom kev, yog li peb yuav tsum tau ua kom zoo dua qub thiab txhim kho cov thev naus laus zis kom tsis txhob muaj cov teeb meem inevitable.
