Ngokweemfuno zobuchwepheshe zabakhiqizi abahlukeneyo, iinkqubo zokulinganisa ubude beetyhubhu ezichanekileyo kunye neendlela ezahlukeneyo zokulinganisa ubude. Kukho oku kulandelayo:
1, Umlinganiselo wobude begrayiti
Umgaqo osisiseko ngulo: iziphelo zangaphandle zeetyhubhu ezichanekileyo zibonelelwa ubude obubini obusisigxina be-grating, ukusetyenziswa kwe-rodless cylinder eqhutywa i-grating kufuphi neziphelo zetyhubhu ezichanekileyo, usebenzisa ukuphazamiseka kokukhanya ukufezekisa umlinganiselo ochanekileyo wobude bombhobho.
Ibonakaliswa ngokuchaneka okuphezulu. Kodwa isikali siyabiza kwaye kunzima ukusigcina, impembelelo yothuli kunye nokungcangcazela yindawo ebuthathaka kakhulu.

2, Umlinganiselo wobude bekhamera.
Umlinganiselo wobude bekhamera kukusetyenziswa kokulungiswa komfanekiso ukuphumeza ukuchaneka kwetyhubhu ubude bokulinganisa ubude, umgaqo-siseko luluhlu olulinganayo lokutshintsha kweefoto zombane ezifakwe kwityhubhu yokuhambisa echanekileyo ngexesha elithile, ukwanda kokukhanya kunye nekhamera kwelinye icandelo. Xa iityhubhu ezichanekileyo kulo mmandla zinokumiselwa ngokuchaneka kwetyhubhu yobude beekhamera zithwebula umfanekiso kwiscreen kwindawo esekwe kwiswitshi yombane.
Iimpawu zifumaneka kumlinganiselo we-intanethi, iibhubhu ezichanekileyo zinokufumaneka ngokulinganisa ubude bedatha xa ummandla omde, akukho xesha. Ukunqongophala: Ukuba awufumani mthombo wokukhanya we-ad hoc, iityhubhu ezichanekileyo ziya kuba phantsi kokuphazamiseka ngaphandle kokukhanya, kodwa emva kokusebenzisa ukukhanya ngenxa ye-ad hoc precision iityhubhu emva kokuphela kwetyhubhu ene-chamfered ngelixa ukukhanya okuphezulu okukhanyayo kunamandla kakhulu, kunokwenzeka. ukwenza iimpazamo zokufunda.

3, I-encoder yokulinganisa ubude
Umgaqo kukufaka i-encoder kwi-cylinder kwi-cylinder ukukhuthaza ukusetyenziswa kweetyhubhu ezichanekileyo kwi-roller movement kwelinye icala le-equidistant enyukayo uchungechunge lokutshintsha kwe-photoelectric, iityhubhu ezichanekileyo zidibene xa i-photoelectric switch cylinders ityhala i-tube ekupheleni, ukusuka kwi-encoding readings yokurekhoda, iguqule i-stroke ye-cylinder, ukuze ukwazi ukubala ubude beetyhubhu ezichanekileyo.
Iphawulwa ngesidingo sokunyusa iityhubhu ezichanekileyo zokulinganisa ubude. Ukongeza, kukho utshintsho oluthile lwe-photoelectric lufumanisa impazamo, unokufuna ukulinganiswa ngokupheleleyo.

4, Uphuculo lokulinganisa ubude be-encoder
Le ndlela yimilinganiselo engathanga ngqo, ngokulinganisa umgama phakathi kweetyhubhu ezichanekileyo ezimbini kunye nendawo yesalathiso ehambelanayo ngokungangqalanga kulinganiswe ubude betyhubhu echanekileyo. Kwiityhubhu ezichanekileyo zombini iziphelo zesikhululo sokulinganisa zimise imoto ende, indawo yokuqala yi-zero isikhundla, isithuba L. Emva koko uhambise ubude betyhubhu echanekileyo yomhleli ukuya ekupheleni komgama ohanjiweyo (L2, L3), L-L2- I-L3, bubude beetyhubhu ezichanekileyo.
