Ulwahlulo olwahlukileyo lweendlela zokulinganisa

Indlela yokulinganisa kukufumana iziphumo zokulinganisa ngokusekelwe kumgaqo othile wokulinganisa, indlela yokulinganisa yahlulwe kwiindidi ezahlukeneyo, nazi ezinye cUmamamalunga neendlela zokulinganisa.

Indlela yokulinganisa ngokuthe ngqo yindlela enokufumana ngokuthe ngqo ixabiso elilinganisiweyo, njengokulinganisa ubude benxalenye ngokusebenzisa i-vernier caliper kunye nokulinganisa ububanzi bomngxuma nge-micrometer.

Indlela yokulinganisa engathanga ngqo yindlela yokufumana ixabiso elilinganisiweyo ngokulinganisa ezinye izixa ezinobudlelwane bomsebenzi. Umzekelo, umatshini wokulinganisa olungelelanisiweyo, umatshini wokulinganisa obonakalayokunye ne-laser Umatshini wokulinganisa zonke ziindlela zokulinganisa ezingathanga ngqo.

Indlela yokulinganisa uqhagamshelwano yindlela yokulinganisa apho isenzi sezixhobo zokulinganisa sinxibelelana nomphezulu wenxalenye. Iindlela eziqhelekileyo zokulinganisa uqhagamshelwano ziquka: i-vernier caliper, i-micrometer, i-styli yokulinganisa kunye nomatshini wokulinganisa ingalo edibeneyo, njl. Ukulinganisa uqhagamshelwano kuqheleke kakhulu kwizicelo zangoku zoshishino. Kubonakaliswa kukuthembeka okuphezulu, ukuchaneka okuphezulu kunye nokuphindaphinda okuhle. Nangona kunjalo, ingxaki yokulinganisa uqhagamshelwano kukuba amandla okudibanisa umlinganiselo anokubangela ukuguquguquka kwisixhobo sokulinganisa kunye nomphezulu wenxalenye (njengomphezulu othambileyo), okunokuchaphazela ukungaqiniseki kokulinganisa.

Ukulinganisa okungadibaniyo yindlela yokulinganisa ukuba isenzi sezixhobo zokulinganisa asiqhagamshelani nomphezulu wenxalenye. Iindlela eziqhelekileyo zokulinganisa ezingadibaniyo ziquka ukulinganisa okubonakalayo, ukulinganisa nge-laser, i-tool microscopy, njl. Iingenelo zokulinganisa okungadibaniyo kukuba isenzi sokulinganisa asidibani nomphezulu olinganiswayo, iindawo eziza kulinganiswa umphezulu aziyi kubangela monakalo, zilungele ngakumbi iindawo ezintsonkothileyo zomphezulu kunye nokulinganisa umphezulu othambileyo. Ingxaki yayo kukuchaneka okungekho phezulu njengokuchaneka kokulinganisa koqhagamshelwano.

Umatshini wokulinganisa umbono yindlela eqhelekileyo yokulinganisa engangqalanga kunye nokulinganisa ngokungangqalanga. Isixhobo sokulinganisa ividiyo esinemilinganiselo emibini sisebenzisa i-hardware ngokwayo (i-CCD, i-eyepiece, umgca wedatha ojolise ngqo, ikhadi lokufumana ividiyo) sinokuthatha umfanekiso ngentambo ukuya kwikhadi lokufumana idatha yekhompyutha, emva kokuthathwa imifanekiso ngu Isoftware kwisikrini sekhompyutha, kunye nokulinganisa ngokukhawuleza. Isixhobo sokulinganisa esibonakalayo sinokufunda ixabiso lokufuduka kwerula ye-optical ngokukhawuleza kwaye sifumane isiphumo esifunekayo ngokusebenzisa imodyuli yesoftware ngokusekwe kwi-spatial geometry. Igrafu iveliswa kwisikrini ukuze isetyenziswe ngumqhubi ukulawula umfanekiso, ukuze kubonwe ngokucacileyo ukuphambuka okunokwenzeka kwesiphumo sokulinganisa.

I-CMM ngumzekelo oqhelekileyo wokulinganisa uqhagamshelwano kunye nokulinganisa okungathanga ngqo. Ukulinganisa okune-coordinate ezintathu yindlela yokufumana ulwazi lwe-coordinate yomphezulu wenxalenye kwindawo ethile yokulinganisa, kwaye ukwenza ulwazi lwemilo yento lube yidijithali kukwabizwa ngokuba yi-"sampling". La maxabiso e-sampling lulwazi oluhlukeneyo lwe-spatial point coordinate, endaweni yeempawu ezithile zejometri zobukhulu, indawo kunye nolunye ulwazi. Inkqubo yokulinganisa icutshungulwa ngoluhlu lwamanqaku okulinganisa, kwaye i-geometric eigenvalues ​​​​ehambelanayo ikhutshwa ukuze kufunyanwe iziphumo zokulinganisa ezifunekayo.
