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 izinto ezithile ezenza ukuba vectoring yenzeke ngaphandle kwentloko encinci. Phakathi kwezi fomati zomfanekiso, i-png okanye i-tiff iya kunika iziphumo ezingcono, ngelixa i-jpg phantse ayinakwenzeka; Isisombululo apho sasithunyelwe khona sikwachaphazela, kuba ukuba siguqulwe ukusuka kwimodyuli yoshicilelo okanye yokuthumela kwelinye ilizwe, iya kuba nesikali esidityaniswa nobungakanani bephepha, ubukhulu bephepha, isisombululo esingcono kunokulindeleka okanye ubuncinci iimeko ezingcono kune isikrini esilula sokuprinta.

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 ndibize umfanekiso wesalathiso, ndiwubeke kancinci ngaphandle kwala manqaku. Emva koko ndibeke amanqaku afanayo kumbala owahlukileyo, ndinqumleza ngemigca eluhlaza, ndihlala ndisebenzisa ubukhulu bokuzibaxa ukuze zibonakale. Kwaye ekugqibeleni ndisebenzisa "ukuhlela, i-warp" kumphathi we-raster, ndisebenzise amanqaku amane olawulo njengoko kubonisiwe kumfanekiso. Kuya kufuneka ngoku ube nakho ukwenza i-vectorize ukuya esikalini.

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 iMicrostation Descartes V8i. Nangona oku kusebenza ngokufanayo kwiinguqulelo zangaphambili.

Yenza i-Descartes izixhoboimephu ekhishwe kwivolNgenxa yoko senza "izixhobo, i-raster, i-raster ilahle i-edit”Kwaye ibonisa ibha equlethe izixhobo ezisisiseko zokwenza umfanekiso.

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

Khetha imaski. I-icon yokuqala ikuvumela ukuba wenze iimaski, ngokusekwe kwiikhrayitheriya, kule meko ndiza kusebenzisa imibala, ebonisa ukuba ndifuna ukongeza iorenji kwimaski. Kuya kufuneka usondele embindini womgca, kwaye ukhethe ibhokisi kwindawo apho umbala ubonakala ucabalele. Ukuqwalasela umbala ofuna ukubonisa imaski, yenza ukhetho "Ingxoxo yencoko yombala"Kwimeko yam ndikhethe uluhlaza. Kuyenzeka ukuba wenze izikhumba ezininzi kwaye ugcine ubumbeko kwifomathi ye .msk

Kwangoko okukhethiweyo kwimask kuguqula umbala obonisiweyo (luhlaza). Unokongeza eminye imibala kwimaski enye, okanye ubathabathe.

imephu ekhishwe kwivolVectorize iindidi. Siza kwakha izangqa ezibonwayo kwinani leebhloko, kuba oku kusicela kwirediyasi kwaye emva koko kufuneka sibambe umgca wesangqa ngasinye. Kulula kakhulu, ndisebenzise umbala we-magenta kunye nobukhulu obaneleyo bezinto ezibonakalayo. Kuya kufuneka uchaze ububanzi bomgca ophezulu, oku kwenziwa ngokulinganisa umgama ogqitha ububanzi bomgca emfanekisweni. Kulawulo olungcono, kufanelekile ukuxelela ukuba icime umfanekiso oveziweyo.

UkuQinisekisa.  Ukuze ugweme ukwenza amacandelo angaphezulu ngenxa ye pixelated, into yesiqhelo inikwe. Umzekelo yinto engaqhelekanga, jonga indlela imigca echaphazeleka ngayo yi-pixelation.

Vectorize imida kunye ne-topology. Ngoku ndifuna ukwenza ikhompyuter kwimida, ukuba ndenze imaski eyahlukileyo yemida yeapile, ibiya kuba nengxaki yokuba ngekhe bacoceke ngokwendawo engaphezulu. Ukwenza oku, ndongeza iorenji kunye nomnyama kwimaski, emva koko ndichukumisa iivektri ngokwahlukeneyo. Umqondiso kukuba zonke ziya kubekwa kumbala wemaski, emva koko zichukunyiswe kuphela kusetyenziswa ukhetho "guqula imigca"

Elula, nantso ke. Bona inkcukacha ezandisiweyo, zokuba iindawo ziye zaqwalaselwa ngokugcina ngokungangqinelani kweendawo ezimi kuzo, ii-node zingagcinwa njengefomathi yefomathi ye-.nod. Unokukhetha utshintsho lombala okanye inqanaba xa ufuna, yile nto ndiyenzileyo ukwahlula umda webhloko kwipropathi nokuba ndisebenza ngemaski enye.

Guqula umbhalo. Kule nto, zikhona ezinye izixhobo ezikuvumela ukuba ukhethe ngokuthe tye, ujikeleze, isicatshulwa esiphakathi, phakathi kwabanye, ngokusebenzisa i-OCR. Kulapho kukuguqula iibhloko (iiseli).

imephu ekhishwe kwivol

imephu ekhishwe kwivol Ezinye iindlela zokukhetha. Nje ukuba kufakwe imaski, imisebenzi enokusetyenziswa ibandakanya:

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. Ndilinganise umgama ukusuka ngaphambili kwipropathi yenombolo 2, kwaye indinike i-28.9611 yeemitha, eyokuqala yayingu-29.00, ukuyikhupha ngeenyawo ngeenyawo ngekhe kwenze mahluko, kodwa kancinci, ngetheyibhile yokufaka ikhowudi kunokuba kubi kakhulu. Kule ndlela ichanekileyo, izinto ezininzi kufuneka ziqwalaselwe, ezinje ngomgangatho
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.

Impendulo enye kwi "Guqula imifanekiso ibe yivektha"

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