Kodi ukadaulo wa OCR ndi chiyani?
Optical Character Recognition (Chingerezi: Optical Character Recognition, OCR) imatanthawuza njira yosanthula ndi kuzindikira mafayilo azithunzi azinthu zolembedwa kuti mupeze zolemba ndi masanjidwe.
Zofanana ndi kuzindikira kwa zithunzi ndi ukadaulo wa masomphenya a makina, njira yopangira ukadaulo wa OCR imagawidwanso muzolowera, kusanja-kukonza, kukonza kwapakati, kukonzanso pambuyo ndi kutulutsa.
lowani
Pakuti osiyana fano akamagwiritsa, pali osiyana yosungirako akamagwiritsa ndi njira zosiyanasiyana psinjika.Pakadali pano, pali OpenCV, CxImage, ndi zina.
Pre-processing - binarization
Zithunzi zambiri zojambulidwa ndi makamera a digito masiku ano ndi zithunzi zamitundu, zomwe zili ndi chidziwitso chochuluka ndipo sizoyenera kuukadaulo wa OCR.
Kwa zomwe zili pachithunzichi, titha kungochigawa kukhala choyambirira komanso chakumbuyo.Kuti kompyuta ikhale yofulumira komanso kuti izichita bwino mawerengedwe okhudzana ndi OCR, tiyenera kukonza chithunzi chamtundu kaye, kuti zidziwitso zakutsogolo ndi zam'mbuyo zokha zikhalebe pachithunzichi.Binarization imathanso kumveka ngati "wakuda ndi oyera".
kuchepetsa phokoso la zithunzi
Kwa zithunzi zosiyana, tanthawuzo la phokoso likhoza kukhala losiyana, ndipo ndondomeko yowonongeka molingana ndi makhalidwe a phokoso imatchedwa kuchepetsa phokoso.
pendekeka kukonza
Chifukwa ogwiritsa ntchito wamba, akamajambula zikalata, zimakhala zovuta kuwombera kwathunthu mogwirizana ndi kutsata kopingasa komanso koyima, kotero zithunzi zomwe zatengedwa mosakayikira zidzasokonekera, zomwe zimafuna kuti pulogalamu yokonza zithunzi ikonze.
Kukonzekera kwapakati - kusanthula masanjidwe
Njira yogawa zithunzi m'ndime ndi nthambi imatchedwa kusanthula masanjidwe.Chifukwa cha kusiyanasiyana ndi zovuta za zolemba zenizeni, sitepe iyi ikufunikabe kukonzedwa.
kudula khalidwe
Chifukwa cha kuchepa kwa kujambula ndi kulemba, zilembo nthawi zambiri zimakakamira ndipo zolembera zimasweka.Kugwiritsa ntchito zithunzi zotere pakuwunika kwa OCR kudzachepetsa kwambiri magwiridwe antchito a OCR.Chifukwa chake, magawo amafunikira, ndiko kuti, kulekanitsa zilembo zosiyanasiyana.
Kuzindikira khalidwe
Poyamba, kufananitsa ma template kumagwiritsidwa ntchito makamaka, ndipo pambuyo pake, kutulutsa mawonekedwe kumagwiritsidwa ntchito makamaka.Chifukwa cha chikoka cha zinthu monga kusamutsidwa kwa mawu, makulidwe a sitiroko, cholembera chosweka, zomatira, kuzungulira, ndi zina zambiri, zovuta zotulutsa mawonekedwe zimakhudzidwa kwambiri.
Kubwezeretsanso masanjidwe
Anthu akuyembekeza kuti zolemba zodziwika zimakonzedwabe ngati chithunzi choyambirira, ndipo ndime, malo, ndi dongosolo zimatuluka ku zikalata za Mawu, zolemba za PDF, ndi zina zambiri, ndipo njirayi imatchedwa kubwezeretsanso masanjidwe.
positi processing
Malingana ndi mgwirizano wa chinenero china, zotsatira zozindikiritsa zimakonzedwa.
zotuluka
Kutulutsa zilembo zozindikirika ngati zolemba mumtundu wina.
Kodi kugwiritsa ntchito ma terminals am'manja kutengera ukadaulo wa OCR ndi chiyani?
Kupyolera mu PDA yonyamula m'manja yodzaza ndi pulogalamu yozindikiritsa mawonekedwe a OCR, ntchito zambiri zitha kuzindikirika, monga: kuzindikira mbale yagalimoto, kuzindikira nambala yachidebe, kuzindikira label kulemera kwa ng'ombe ndi nyama yankhumba, kuzindikira malo owerengeka ndi makina a pasipoti, kuzindikira kuwerengera kwa mita yamagetsi. , koyilo yachitsulo Kuzindikira zilembo zopopera.
