Nyob rau hauv tus txheej txheem ntawm kev siv lub multimedia qhia tag nrho-hauv-ib lub tshuab, qhov kov yuav raug me ntsis offset, uas yuav cuam tshuam rau cov nyhuv kov. Cov xwm txheej zoo li no yuav cuam tshuam rau peb qhov kev siv ib txwm muaj. Yog tias cov chaw tsim khoom tso cov software kov hauv lub tshuab. Qhov no tuaj yeem raug kho ncaj qha, tab sis feem ntau nws yuav tsis muab tso ncaj qha rau hauv lub tshuab. Yog tias muab tso rau hauv nws, nws ntshai ntawm kev ua haujlwm tsis raug, thiab nws yuav ua rau muaj teeb meem rau kev kho. Yog li yog tias qhov teeb meem zoo li no tshwm sim, koj tuaj yeem tiv tauj lub chaw tsim khoom rau kev kho software.
Lwm qhov xwm txheej yog qhov kev kho tsis muaj txiaj ntsig. Qhov no yuav tsum tau sim nrog kev kho software los ntawm cov chaw tsim khoom kom pom tias muaj teeb meem nrog qhov kov. Yog tias muaj teeb meem, koj yuav tsum hu rau lub chaw tsim khoom rau kev saib xyuas tom qab muag.
Lwm qhov yog tias qhov kov software nrhiav pom tsis yog qhov phem, thiab qhov kov calibration yog biased. Ntawm no koj tuaj yeem tshem tawm cov ntaub ntawv los ntawm kov cov tswj vaj huam sib luag pc. Yog tias nws tseem tsis tau ua haujlwm, ntawm no koj tuaj yeem pom tias qhov kov yog offset rau sab ntawd, tsuas yog tshem tawm cov plaub-txheej ntsia hlau sib txuas, thiab saib seb qhov kov infrared lub teeb bar yog daig nyob rau hauv qhov chaw, thiab yog tias muaj, txav nws mus. .
