Izifo zenzwa zangoku zahluka ngokubanzi ngokomgaqo kunye nesakhiwo. Ungalukhetha njani izinzwa ngokuvakalayo ngokwenjongo ethile yenjongo, injongo yokulinganisa kunye nemeko yokulinganisa yingxaki yokuqala ekufuneka isonjululwe xa ulinganisa inani elithile. Xa i-sensor imisiwe, indlela yokulinganisa yokulinganisa yokuthelekisa kunye nezixhobo zokulinganisa zinokugqitywa. Impumelelo okanye ukusilela kweziphumo zokulinganisa kuxhomekeka kumgangatho omkhulu wokuba ngaba ukhetho lweenzwa lusengqiqweni.

1. Chonga uhlobo lwenzwa ngokwenjongo yokulinganisa kunye nendawo yokulinganisa.

Ukwenza umlinganiso othile, kufuneka kuqala siqwalasele ukuba loluphi uhlobo lwesomansol olusetyenzisiweyo, ekufuneka limisiwe emva kokuhlalutya izinto ezininzi. Kuba, nokuba kulinganiselwe ubungakanani bomzimba, zininzi iindidi zokukhetha kuzo, kwaye yeyiphi efanelekileyo, kufuneka siqwalasele ezi ngxaki zichaziweyo ngokweempawu zenzwayo: ubungakanani benqanaba lokulinganisa; Iimfuno zesikhundla esilinganiswe kwivolumu yenzwa; Nokuba indlela yendlela yokulinganisa inxibelelana okanye engaqhagamshelwanga; Indlela yokukhupha umqondiso, iwindows okanye imilinganiselo engaqhakamshelanga; Umthombo wenzwa, wasekhaya okanye ongeniswayo, ofikelelekayo, okanye oziphuhliswe.

Emva kokuthathela ingqalelo ezi ngxaki zingasentla, sinokuchonga ukuba loluphi uhlobo lwejensor ukuba ukhethe, kwaye emva koko uqwalasele isalathiso sentsebenzo ethile yenzwa.

2, Ukhetho lwemvakalelo

Ngokubanzi, ngaphakathi koluhlu lwenzwane yenzwa, iphakame imvakalelo yenzwa, engcono. Kungenxa yokuba kuphela xa imvakalelo iphezulu, ixabiso lomqondiso wokuphuma ohambelana notshintsho olulinganisiweyo luphantsi, oluyingenelo ukulungisa umqondiso. Nangona kunjalo, kufuneka kuqatshelwe ukuba imvakalelo yenzwa yenzwa iphelile, kwaye ingxolo yangaphandle engahambelaniyo nomlinganiso kulula, kwaye iya kuba yinkqubo yokuchaneka kwemilinganiselo. Ke ngoko, kuyafuneka ukuba i-sensor ngokwayo ifanele ibe nomyinge ophezulu wengxolo kwaye uzame konke okusemandleni ukunciphisa imiqondiso yokuphazamiseka eyaziwe ngaphandle.

Imvakalelo yenzwane yenzwane isalathiso. Xa inani elilinganayo alisebenzi, kwaye kuya kufuneka ukuba kubekho imiyalelo yayo ukuba ibe phezulu, oosoyenzi ngemvakalelo ephantsi kwezinye iindlela kufuneka zikhethwe; Ukuba i-vector elilinganiswe yi-vector ye-vectoriment, incinci imvakalelo yovelwano yenzwane, ingcono.
