Imigqa nemivimbo eminingi ukwakheka kancane kancane kweso lapho, lapho ulibuka likude noma usondeza isithombe, singathola ukuthi lokho kukhanya kucaca kanjani. Ngaphandle kwalokho inemibala eqenjini elikhulu lezithombe ezinethoni elula.
Into enelukuluku ngalokhu kuhlola okwenziwe ngepeni ukuthi kukhona indlela yokwenza lo mphumela ngokwamanani ngokulandela ama-tangents wamajika wezimo zeso noma wento esifuna ukuyimela. Isiphakamiso esithandekayo esivela kumculi ongaziwa kuwebhu esifanelekile ngokuphelele ukwazi i-algorithm ye-RANSAC.
Inqubo ye kwenze ngokwamanani Kungafingqwa ngokuthi:
- Guqula isithombe sibe mnyama nomhlophe
- Dala ikhanvasi engenalutho
- Dweba umugqa owodwa kumakhophi angamakhulu ambalwa wendwangu
- Bala umehluko phakathi kwangempela kanye namakhanseli
- Thatha okukodwa okunomehluko omncane
- Le nqubo iyaphindwa kusuka esinyathelweni sesithathu cishe izikhathi eziyinkulungwane
Kwenziwe ngokuphelele, kufanele sikwenze cishe izikhathi eziyikhulu futhi ekugcineni sikhethe isithombe esilingisa kangcono imodeli ebesingayisebenzisa. Kungaba yisicefe kancane, kepha sizozisindisa thina ngokwethu uma sifuna ukuyidweba ngesandla njengoba kwenzeka kulingo esabelana ngalo lapha. Yebo ufuna ukusindisa inqubo, Woza lapha.
Ekugcineni sikhuluma nge-algorithm ye-RANSAC leyo yanyatheliswa nguFischler noBolles ngo-1981 futhi lokho sekusetshenzisiwe ekuhlaziyweni kwesithombe. I-RANSAC inekhono elimangalisayo lokuhlinzeka ngokulingana okuhle kusuka kudatha engcoliswe ngamanani amakhulu wabathengisi, okungaphezulu kakhulu kunamaphesenti angama-50 okungumkhawulo ongenakunqotshwa kwamanye amasu wokulinganisa okuqinile.
I-algorithm funa imodeli enhle kakhulu ucubungula wonke amaphikseli we-contour kufaka phakathi lawo angahambelani nemodeli efunwayo. Ngokungahleliwe ukhetha isampula yamaphikseli, lapho s amaphuzu adingekayo ukusungula amapharamitha wemodeli.
Una isiphakamiso sokudala esithakazelisayo njengesilingo. Uma ufuna ukwazi enye, ngonyaka nje odlule sishicilele eyodwa yenziwe nge-CSS3D HTML5.
