Ngokwezidingo zobuchwepheshe zabakhiqizi abahlukene, amasistimu wokulinganisa amashubhu anembayo anezinhlobonhlobo zezindlela zokulinganisa ubude.Kukhona okulandelayo:
1, Isilinganiso sobude begridi
Isimiso esiyisisekelo siwukuthi: imiphetho yangaphandle yamashubhu anembayo inikezwa ubude obungaguquki obubili begrayiti, ukusetshenziswa kwe-grating engenasilinda eqhutshwa eduze kokuphela kwamashubhu okunemba, kusetshenziswa ukuphazamiseka kokukhanya ukuze kufinyelelwe isilinganiso esinembile sobude beshubhu.
Ibonakala ngokunemba okuphezulu.Kodwa isikali siyabiza futhi kunzima ukusigcina, umthelela wothuli nokudlidliza kuyisizinda esibucayi kakhulu.

2, Isilinganiso sobude bekhamera.
Isilinganiso sobude bekhamera siwukusetshenziswa kokucutshungulwa kwesithombe ukuze kufinyelelwe ukunemba kobude besilinganiso sobude bamashubhu, isimiso siwuchungechunge olulinganayo lwamaswishi ezithombe zikagesi ezifakwe kushubhu yokudlulisa i-roller enembile isikhathi esithile, ukwanda kokukhanya nekhamera kwesinye isigaba.Lapho amashubhu anembayo kulesi sifunda angase anqunywe amakhamera wobude beshubhu enembayo athwebula isithombe esibukweni endaweni esekelwe enguqulweni kagesi wesithombe.
Izici zitholakalela ukulinganisa ku-inthanethi, amashubhu anembayo angatholwa ngokukala ubude bedatha uma indawo ende, kungekho sikhawu.Ukushoda ngukuthi: Uma ungewona umthombo wokukhanya wesikhashana, amashubhu anembayo azoba ngaphansi kokuphazamiseka ngaphandle kokukhanya, kodwa ngemva kokusebenzisa ukukhanya ngenxa yamashubhu anembayo wesikhashana ngemva kokuphela kweshubhu e-chamfered kuyilapho ukukhanya okuphezulu kokukhanya kunamandla kakhulu, kungenzeka. ukubangela amaphutha okufunda.

3, Ubude bokulinganisa isifaki khodi
Umgomo ukufaka isishumeki sekhodi kusilinda kusilinda ukuze kuthuthukiswe ukusetshenziswa kwamashubhu anemba ekunyakazeni kwama-roller ngakolunye uhlangothi lochungechunge olukhulayo olulinganayo lokushintshwa kwe-photoelectric, amashubhu anembile ahlangatshezwana nawo lapho amasilinda okushintsha kwesithombe kagesi ephusha ukuphela kweshubhu, kusukela ekufundweni kombhalo wekhodi oqoshiwe, kuguqule ukushaywa kwesilinda, ukuze ukwazi ukubala ubude bamashubhu anembayo.
Ibonakala ngesidingo sokuphakamisa ukunemba kwamashubhu okulinganisa ubude.Ngaphezu kwalokho, kukhona inkinobho ye-photoelectric ethola iphutha, kungase kudingeke ukuba ulinganiswe ngokugcwele.

4, Isifaki khodi sokulinganisa ubude esithuthukisiwe
Le ndlela iwukulinganisa okungaqondile, ngokulinganisa ibanga eliphakathi kwamashubhu amabili anemba ekugcineni nendawo eyireferensi efanelekile elinganiswe ngokungaqondile ubude beshubhu lokunemba.Kumashubhu anembayo womabili amaphethelo esiteshi sokulinganisa amise imoto ende, indawo yokuqala iyiziro, isikhala L. Bese uhambisa ubude beshubhu lokunemba lomhleli ekupheleni kwebanga ngalinye elihanjiwe (L2, L3), L-L2- I-L3, ubude bamashubhu anembayo.
