Umsebenzi wesistimu yokuhlela ithrekhi yamathuluzi yethuluzi lomshini we-nc

Uhlelo lokuhlela ithrekhi yamathuluzi lwakhiwe ukuguqulwa kwethrekhi yamathuluzi, ukuhlela imigqa yokusika, ukuboniswa kwezithombe zethrekhi yamathuluzi, ukulayisha kanye nokukhishwa kwethrekhi yamathuluzi, njll.

1. Ukuguqulwa kweJomethrikhi

Okuqukethwe kokuguqulwa kwejometri kwendlela yamathuluzi kufaka phakathi ukuhlolwa, ukujikeleza kanye nesithombe sesibuko. Ekuguqulweni kokuhumusha, isikhungo sommese kuphela esivunyelwe ukushintsha, futhi i-vector ye-axis yommese ihlala ingashintshi. Ekuguqulweni kokujikeleza kanye nesithombe sesibuko, inani elifanele lesikhungo sommese kanye nomphini wommese liyashintsha.

2. Guqula ukuguqulwa

I-transpose ushintsho endleleni yokuhamba ukusuka endleleni yokuqala ukuya endleleni entsha yokuhamba. Inhloso yokuguqulwa kwe-transpose ingaba kuphela indlela yokuxhumana kokusika (isinxephezelo se-semi-precision sethuluzi le-3d siyasebenza) noma indlela yesikhungo samathuluzi esiyindilinga, futhi inani lephutha alikho ngaphezu kwenani elivunyelwe lapho kwenziwa imishini endleleni entsha yamathuluzi. Njengoba ukuguqulwa kwe-transposing kungashintshi indlela ye-axis yokusika, ithrekhi yamathuluzi okugaya amaningi ayikwazi ukuguqulwa. Ukuguqulwa kwe-transposing kuphumelela kakhulu endleleni yamathuluzi ekhiqizwe yi-algorithm ehlukanisiwe yepharamitha elinganayo endleleni yokugaya ye-parametric. Kwithrekhi yamathuluzi ekhiqizwe ngezinye izindlela zomugqa we-parametric, imigqa yokusika ingabethelwa ngobude obulinganayo be-arc ngokuya ngamaphuzu acacisiwe ngaphambi kokuguqulwa kwe-transposing, ukuze inani lamaphuzu okuma komugqa ngamunye wokusika lifane futhi lisatshalaliswe ngokulinganayo.

3. Susa

Inhloso yokusebenza kokususa kungaba ithrekhi yamathuluzi endaweni yokuma, ingxenye yokusika, umugqa wokusika, ibhulokhi yokusika noma ngisho nokuhlela konke, noma ingxenye yethrekhi yamathuluzi esinqunyiwe.

4. Umthungi

Into yendlela yamathuluzi okufanele inqunywe kufanele icaciswe kuqala, bese into yokunquma, njengobuso bokuhlola, kufanele icaciswe. Okokugcina, cacisa izingxenye okufanele zisuswe. Ukusebenza kokunquma kudinga i-algorithm yokuhlangana phakathi kwento eqoshiwe (indlela yamathuluzi) nento eqoshiwe (njengobuso bokuhlola).

5. Buyisela esimweni

Imodi yokusebenza yokubuyisela ihlanganisa izinhlobo ezimbili: eyodwa ukubuyisa umhlaba wonke, okungukuthi, ukubuyisa zonke izinto zethrekhi yamathuluzi asusiwe; Enye ukubuyisa okujikelezayo, okungukuthi, ngokusho komsebenzi wokususa ngokulandelana okuphambene ukuze kubuyiselwe into yethrekhi yamathuluzi asusiwe, isikhathi ngasinye lapho umsebenzi wokubuyisela, buyisela umsebenzi wokususa into yethrekhi yamathuluzi asusiwe, kuze kube yilapho into yethrekhi yamathuluzi esusiwe isibuyiselwe.

6. Ukuhlanganiswa kwe-Homogenization

Into yokusebenza ehlanganisiwe ingaba yindlela eyodwa eya endleleni, noma ingaba yindlela yethuluzi kukho konke ukuhlela. Umsebenzi we-homogenization uhlanganisa okulandelayo:

(1) umugqa wokusika ngokwephuzu u-N ukuze kube nokubethela okulinganayo kobude be-arc. Indlela yile: okokuqala, ukufakwa kwejika lomugqa wokusika, bese kuba ngokwephuzu lobude be-arc lejika elihlukanisiwe kuya kumaphuzu angu-N. Ivektha evamile ye-axis yokusika kanye nendiza yokushintshana kuqala iguqulwa ibe yindlela yokuphela kwe-vektha, bese ifakwa futhi ihlukaniswe, bese ekugcineni iguqulwa ibe yi-unit vector.

(2) kumugqa wokusika ngokwephutha elinikeziwe, indlela yokuhlola ipharamitha isetshenziswa ukuze kuhlolwe iphuzu lesikhundla ngqo.

(3) faka iphuzu lokusika phakathi kwamaphuzu amabili okuma ngokuhlanganiswa okuqondile.

7. Hlela

Uma yonke eminye imisebenzi yokuhlela isiqediwe, ithrekhi yamathuluzi ingaxhunywa futhi ihlelwe.Okokuqala, isiqondiso sethuluzi kufanele sichazwe (okungangqubuzani nesiqondiso sethuluzi esibekwe uhlelo ngesikhathi sokubalwa kwendlela yamathuluzi), isiqondiso sethuluzi singangqubuzana nendlela yamathuluzi ebekwe uhlelo ngesikhathi sokubalwa kwendlela yamathuluzi, futhi ukuphakama kokuphakamisa ithuluzi kufanele kunikezwe isiqondiso esisodwa sethuluzi.Uma le mithetho yamukelwe, uhlelo luzohlela ngokuzenzakalelayo ukuphuma kwamathrekhi amathuluzi ekuhleleni.
