Ka Whakakapia e ngā Hua OCR/OCV ngā Matawai Tuku Iho

He aha te Whakamārama Pūāhua Whatu (OCR)?

He tukanga pakihi whai hua te hangarau mōhio pūāhua whatu (OCR) e penapena ana i te wā, te utu me ētahi atu rauemi mā te whakamahi i ngā āheinga tango raraunga me te rokiroki aunoa.

Ko te mōhio ki ngā pūāhua whatu (OCR) e kiia ana i ētahi wā ko te mōhio ki ngā tuhinga. Ka tangohia, ka whakamahia anōtia hoki e te kaupapa OCR ngā raraunga mai i ngā tuhinga kua matawaihia, ngā whakaahua kāmera me ngā kōnae PDF whakaahua-anake. Ka tohua e te pūmanawa OCR ngā reta i runga i te ahua, ka whakaurua ki roto i ngā kupu, kātahi ka whakaurua ngā kupu ki roto i ngā rerenga kōrero, ā, ka taea te uru atu me te whakatika i ngā ihirangi taketake. Ka whakakorea hoki te hiahia mō te whakauru raraunga ā-ringa.

Ka whakamahia e ngā pūnaha OCR he huinga o ngā taputapu me ngā pūmanawa hei huri i ngā tuhinga tūturu, kua tāia ki roto i ngā tuhinga ka taea te pānui e te mīhini. Ka tārua, ka pānui rānei ngā taputapu — pērā i te matawai whatu, i te papa hiko motuhake rānei — i ngā tuhinga; kātahi ka whakahaerehia e te pūmanawa te tukatuka matatau.

Ka taea e te pūmanawa OCR te whakamahi i te mātauranga horihori (AI) hei whakatinana i ngā tikanga matatau ake mō te mōhio ki ngā pūāhua atamai (ICR), pērā i te tautuhi i ngā reo, i ngā momo tuhituhi rānei. Ko te tukanga OCR te mea e whakamahia whānuitia ana hei huri i ngā tuhinga ture, tuhinga hītori rānei hei tuhinga PDF kia taea ai e ngā kaiwhakamahi te whakatika, te whakahōputu me te rapu i ngā tuhinga me te mea kua hangaia ki tētahi tukatuka kupu.

He pēhea te mahi a te mōhio ki ngā pūāhua whatu?

Ka whakamahia e te OCR he matawai hei tukatuka i te āhua tūturu o tētahi tuhinga. Kia tāruatia ngā whārangi katoa, ka hurihia e te pūmanawa OCR te tuhinga hei putanga tae-rua, pango-mā rānei. Ka tātarihia te ahua, te mahere iti rānei kua matawaihia mō ngā wāhi mārama me ngā wāhi pōuri, ā, ka tautuhia ngā wāhi pōuri hei pūāhua me mōhio, ko ngā wāhi mārama ia ka tautuhia hei papamuri. Kātahi ka tukatukahia ngā wāhi pōuri hei kimi i ngā reta reta, i ngā mati tau rānei. Ko te tikanga o tēnei wāhanga ko te arotahi ki tētahi pūāhua, kupu, poraka tuhinga rānei i ia wā. Kātahi ka tautuhia ngā pūāhua mā te whakamahi i tētahi o ngā rauropi e rua — te mōhio tauira, te mōhio āhuatanga rānei.

Ka whakamahia te mōhio tauira ina whāngaihia te kaupapa OCR ki ngā tauira tuhinga i roto i ngā momotuhi me ngā whakatakotoranga rerekē hei whakatairite me te mōhio ki ngā pūāhua i roto i te tuhinga, i te kōnae whakaahua rānei kua matawaihia.

Ka puta te kitenga āhuatanga ina whakamahia e te OCR ngā ture e pā ana ki ngā āhuatanga o tētahi reta, tau rānei hei tautuhi i ngā pūāhua i roto i te tuhinga kua matawaihia. Kei roto i ngā āhuatanga te maha o ngā rārangi koki, ngā rārangi whakawhiti, ngā kōpiko rānei i roto i tētahi pūāhua. Hei tauira, ka rongoatia te reta matua "A" hei rārangi whakarara e rua e tūtaki ana ki tētahi rārangi whakapae i waenganui. Ina tautuhia he pūāhua, ka hurihia hei waehere ASCII (American Standard Code for Information Interchange) e whakamahia ana e ngā pūnaha rorohiko hei whakahaere i ngā mahi whakarerekētanga anō.

Ka tātarihia hoki e te kaupapa OCR te hanganga o te ahua o te tuhinga. Ka wehea te whārangi kia rite ki ngā poraka tuhinga, ngā ripanga, ngā whakaahua rānei. Ka wehea ngā rārangi kia rite ki ngā kupu, kātahi kia rite ki ngā pūāhua. Kia oti te wehewehe i ngā pūāhua, ka whakaritea e te kaupapa ki tētahi huinga whakaahua tauira. Kia oti te tukatuka i ngā taurite katoa, ka whakaatuhia e te kaupapa te tuhinga kua mōhiotia.

He maha ngā whakamahinga o te OCR hei hangarau huna, e whakakaha ana i ngā pūnaha me ngā ratonga rongonui maha i roto i tō tātou oranga o ia rā. Ko ngā whakamahinga nui – engari kāore i te tino mōhiotia – mō te hangarau OCR ko te whakauru raraunga aunoa, te āwhina i ngā matapo me ngā tāngata kanohi kore, me te tātai tuhinga mō ngā miihini rapu, pērā i ngā uruwhenua, ngā pereti nama, ngā nama nama, ngā tauākī peeke, ngā kāri pakihi me te mōhio aunoa ki ngā pereti nama.

 

Ngā āhuatanga ki te whakataurite ki ngā matawai tuku iho:

1. Mama, ngāwari ki te kawe me te tāuta;

2. He poto te wā matawai, ko te wā matawai noa he 1-2S, ā, ka taea e koe te tiki tonu;

3. Utu iti

4. Ka taea e ia te mahi i te OCR mō ngā pikitia kua hopukina, te huri i ngā pikitia hei tuhinga WORD ka taea te whakatika, me te pato aunoa i aua pikitia;

5. Mā te whakauru i te hangarau waea whakaahua kore pepa, ahakoa kāore he mīhini waea whakaahua, ka taea tonu e koe te tuku waea whakaahua, ka tino whakapai ake i te pai o te waea whakaahua;

 

Ngā whakamahinga mō te mōhio ki ngā pūāhua whatu

Ko te whakamahinga rongonui mō te mohio ki ngā pūāhua whatu (OCR) ko te huri i ngā tuhinga pepa kua tāia ki ngā tuhinga tuhinga ka taea te pānui e te mīhini. Kia oti te tukatuka OCR i tētahi tuhinga pepa kua matawaihia, ka taea te whakatika i te tuhinga o te tuhinga mā te whakamahi i tētahi tukatuka kupu pēnei i a Microsoft Word, Google Docs rānei.

Mā te OCR ka taea te arotau i te whakatauira raraunga nui mā te huri i ngā tuhinga pepa me ngā tuhinga whakaahua kua matawaihia ki ngā kōnae pdf ka taea te pānui e te mīhini, ka taea te rapu. Kāore e taea te tukatuka me te tiki mai i ngā mōhiohio nui me te kore e whakamahi tuatahi i te OCR ki ngā tuhinga kāore anō kia kitea he paparanga tuhinga.

Mā te mohio ki ngā tuhinga OCR, ka taea te whakauru i ngā tuhinga kua matawaihia ki roto i tētahi pūnaha raraunga nui e taea ai te pānui i ngā raraunga kiritaki mai i ngā tauākī peeke, ngā kirimana me ētahi atu tuhinga tānga nui. Engari i te tirotiro a ngā kaimahi i ngā tuhinga whakaahua maha me te whāngai ā-ringa i ngā whakaurunga ki roto i tētahi tukanga tukatuka raraunga nui aunoa, ka taea e ngā whakahaere te whakamahi i te OCR hei whakahaere aunoa i te wāhanga whakauru o te keri raraunga. Ka taea e te pūmanawa OCR te tautuhi i te tuhinga i roto i te ahua, te tango tuhinga i roto i ngā pikitia, te tiaki i te kōnae tuhinga me te tautoko i te jpg, jpeg, png, bmp, tiff, pdf me ētahi atu hōputu.

I runga i tēnei kaupapa, kua whai a Hampolwhakarewatangaed he raupapa o ngā kōwae kāmera mai imai i5MP-16MP o te whakamāramatanga. I te tīmatanga o te wāhanga whanaketanga o Hampo, i hangaia e tā mātou tīma tētahi momo kāmera usb 5MP tuatahi mō te matawai tuhinga tere-teitei;Me tete tono mōmākete, Kua whakahoutia ngā kōwae kāmera USB 8MP, 13MP, tae atu ki te 16MPi hangaia. He aha'Heoi anō, ko te hiahia mō te kāmera kotahi, ki ngā kāmera e rua, me ngā kāmera maha e whakamahia ana ki te matawai tuhinga.
