Guqula imifanekiso ukuya kwi vector

Kangangexesha elithile, iitafile output idijithali zaprintwa iimephu umkhondo, ngoko kwafika vuavanyisi, kodwa lo msebenzi ayisetyenziswanga kuphela iimephu zaskenwa kodwa abanye baguquka umfanekiso okanye PDF kwaye musa ukuba ifomati kumda wesangqa.

Inkqubo endiya ku boniswa isebenzisa i-Microstation Descartes, kodwa enye inokuyenza nayiphi na inkqubo: AutoDesk Raster Design (Ngaphambi kokuba i-CAD igule) ArcScan, GIS asibonise (Iimveliso Zoshishino), ndiyakhumbula ukuba ixesha elide ndiyenze ngoCorel Draw.

1. Umfanekiso

Kukho ezinye izinto ezinefuthe vectorization kunokwenzeka ngaphandle yintloko ezincinane. Ezi image format, png okanye TIFF uya ukunika iziphumo ezingcono, lo gama i jpg cishe akunakwenzeka; naye ephembelela isisombululo ukuba kwamanye amazwe, ngokungathi kunjalo aguqulwa kwimodyuli yoshicilelo okanye kumazwe ntolovelo a isikali ezinxulumene ubungakanani bephepha, kokukhona ubungakanani bephepha unokulindela isisombululo ngcono okanye ngcono ubuncinane iimeko ngaphezu kokuba Simple yoshicilelo screen.

imephu ekhishwe kwivol

Umzekelo ndiza sebenzisa i cadastral imephu 1: 1,000 ukuba ethengwe ukusuka Microstation imodyuli ushicilelo, i 24 "x36" sheet TIFF.

2. I-georeference

Imephu enjengale yinto elula yokwenza izinto, kuba iququzelele kwimida. Ndiyidonse le ngongoma usebenzisa umyalelo "indawo yendawo", Kwaye ungena keyin ulungelelaniso kwifom "xy = X ukulungelelanisa, Y ulungelelaniso", Lezo zimbonakalo eziluhlaza okwesibhakabhaka somfanekiso osezantsi.

Emva koko ndabiza umfanekiso wesalathiso, ndawubeka encinane ngaphandle kwale ngongoma. Emva koko ndibeke iingcamango ezifanayo ngemibala eyahlukileyo, ndidibanisa ngemigca eluhlaza, ndisoloko ndisebenzisa ubungqina obugqwethayo ukuze babonakale. Kwaye ekugqibeleni usebenzisa "edit, warp" kumphathi we-raster, ndafaka izicelo ezine zolawulo njengoko kuboniswe kumfanekiso. Ngoku ufanele ukwazi ukutshintshela ukulinganisa.

Nangona i-Microstation i-V8i isekela ukubiza ifayile ye-pdf njengomfanekiso kwaye oku kungenziwa nge-georeferenced kunye nenkqubo yangaphambili, inkqubo ye-vectorization ayisebenzisi kuba ifuna ukuba unamalungelo okubhala. Kuya kubakho ukuyilayisha, kwaye uyigcine njengomfanekiso (iqhosha lasekunene, ndoloze...).

3. Uluhlu

imephu ekhishwe kwivolNdisebenzisa i-Microstation Descartes V8i. Nangona oku kusebenza okufanayo neenguqulelo zangaphambilini.

Yenza i-Descartes izixhobo. imephu ekhishwe kwivolNgenxa yoko senza "izixhobo, i-raster, i-raster ilahle i-edit"Kwaye oko kubonisa ibha equlethe izixhobo ezisisiseko zokucwangciswa komfanekiso.

Siya kwenza umsebenzi kwi-apple ye-15 ukuchaza izicatshulwa into enokuyenza:

Khetha imaski. I-icon yokuqala ikuvumela ukuba udale imaski, ngokusekelwe kwimilinganiselo, kulo mzekelo ndiya kusebenzisa imibala, ebonisa ukuba ndifuna ukongeza i-orange kwimaski. Kufuneka ufike kwinqanaba lomgca, kwaye ukhethe ibhokisi kwindawo apho umbala ukhangeleka. Ukuqwalasela umbala ofuna ukuwubonisa imaski, kwenziwa ngekhetho "Ingxoxo yencoko yombalaKwimeko yam ndikhethile uhlaza. Kwakhona kunokwenzeka ukudala iimpawu ezininzi kwaye ulondoloze ukucwangciswa kwifom .msk

imephu ekhishwe kwivol

Ngokukhawuleza okukhethiweyo kwimaski utshintshe kumbala obonisiweyo (eluhlaza). Ungongeza kwakhona imibala kwimaski efanayo, okanye uwasuse.

imephu ekhishwe kwivolVectorize iindidi. Siza kwakha izangqa ezibonakalayo kwinani leeapulo, ngenxa yale nto siyicelela umsakazo kwaye nje sithinte umgca weeqaqa ngasinye. Elula kakhulu, ndasebenzisa umbala wamagenta kunye nobukhulu obaneleyo kwimicimbi ebonakalayo. Ufanele ucacise ubungakanani bomda obanzi, owenziwe ngokulinganisa umgama ogqithise ububanzi bomgca emfanekisweni. Ukulawula okungcono, kuyafaneleka ukumyalela ukuba asuse umfanekiso ochanekileyo.

UkuQinisekisa. Ukuze ugweme ukwenza amacandelo angaphezulu ngenxa ye pixelated, i-normalization factor is assigned. Umzekelo ungowesiqhelo, funda indlela imizila ifuthe ngayo iipixelated.

imephu ekhishwe kwivol

Vectorize imida kunye ne-topology. Ngoku ndifuna ukukhangela imida, ukuba ngaba ndenze i-mask ngokwahlukileyo kwimida ye-apple ndiza kuba neengxaki ababengayi kuba nocociso lwezobugcisa kwiinkalo zangaphakathi kwemida. Kule nto ndiyongeza umbala we-orange kunye nombala omnyama kwi-mask, ngoko ndiyakuthinta i-vectors ngokwahlukileyo. Isibonakaliso kukuba bonke baya kufakwa kumbala we-mask, ngoko bachaphazela kuphela usebenzisa inketho "guqula imigca"

imephu ekhishwe kwivol

Elula, kunjalo. Jonga iinkcukacha ezongezelelweyo, ukuba iinqununu ziye zaqatshelwa ngokugcina ukufanisana kwezobugcisa kwizandi, iinombolo zingagcinwa njengefayile ye -rmat. Unokukhetha umbala okanye utshintsho kwinqanaba xa ufuna, yiloo nto endiyenzile ukuhlukanisa umda we-apula wepropati ude usebenze kunye nemaski enye.

Guqula umbhalo. Kule zikho ezinye izixhobo, ezikuvumela ukuba ukhethe okungaqhelekanga, ukujikeleza, umbhalo obanzi, phakathi kwabanye, ngokusebenzisa i-OCR. Kukho ukuguqula iibhloko (iiseli).

imephu ekhishwe kwivol

imephu ekhishwe kwivol Ezinye iindlela zokukhetha. Xa kusetyenziswe imaski, phakathi kwemisebenzi enokuthi ifake isicelo:

4. Guqula imizila ngokwalo
5. Ukuguqula indawo epheleleyo ebhalwe kwibhokisi
6. Guqula zonke izinto ezixhunyiwe kwimephu
7. Ukwakha iirveve zamanqanaba (intambo), kufuneka ibe kwifayile ye-3D.
8. Yakha i mibuthano
9. Nciphisa abavini, oku kungenxa yamaketanga omqolo anamaqela amaninzi kakhulu

Ukuchaneka. I Walinganisa ububanzi, ethabathela phambi inombolo yezindlu 2, yaye uye iimitha 28.9611 mna, ezemvelo 29.00, vectorizarlo nihambe wakupha ngokufanayo kodwa kancinci, itheyibhile idijithali kwakuya kuba kubi. Kule ngqo izinto ezininzi kufuneka ziqwalaselwe, ezifana calida
d ye-scan, ukuba ishidi alilinakalisiwe, umlinganiselo wemephu, umgangatho we-pixelated kunye naphezu kwayo yonke i-georeferencing yecandelwana 2 yale post.

Vectorization enkulu.

Ukuba unemifanekiso emibala emibini, okanye ukuba ukhawuleza, kunokwenzeka ukwenza ukhetho olukhulu, nangona oku kufuneka ucinge ngezinye iinkalo:

  • Ukuba imephu iqulethe imida kuphela, emva kokuba kwenziwe iimvavanyo zenkqubo, zenziwe kuphela.
  • Ukuba imephu ineetekisi, ukulungele ukuguqula oku kuqala, ngoko kunye nethuluzi lokucoca iifayile kususe izinto ezingcolileyo
  • Ukuba ukuskena in umbala, kunye scan elamkelekileyo, njenge 1 sheet imaphu: 50,000, unako ukwenza umbala, nokwenza iimaski ezinamagama luncedo (imigca nentaba, izakhiwo, iindlela, igridi, njl) ukwenzela ukuba sisisebenzise ukuze imifanekiso iyunifomu.
  • Xa unamaxwebhu aqhubekekayo, kukhethwa ukubabize zombini, ukwenza ulungiso olwenziwe ngokuzibandakanya kunye ne-vectoring eneempawu ezikhethiweyo ezikhethiweyo.
  • Kucebisekile ukuba wenze ulawulo lwesigxina, ngokukodwa kumalungu kunye neendawo zokusondelana kwemigca.

Enye impendulo "Yitshintsha imifanekiso ukuya kumvolonti"

  1. Ndicinga ukuba kulungile ukuba ndisebenze ne-8.5 kuba kuya kubaluleke kakhulu.
