I. Isingeniso

1.1 Izinqumo Zokwenziwa Kwezesekeli KamaraTeknoloji

Izithombe zendabuko zidinga abasebenzisi ukuba baphawule iphuzu lokugxila ngaphambi kokuthatha isithombe. Uma isithombe sithathwe, ukugxila kuqinisekisiwe, kushiya akukho ndawo yokulungisa. Lokhu kunciphisa ukusebenza kwazo ezimeni lapho isihloko sishukumiseka ngokushesha noma lapho ukugxila okufunwayo kushintsha ngemuva kokuthathwa, njengokuthatha izithombe zezemidlalo ezisheshayo noma ukuhlola isimo esiguquguqukayo esinokujula okuningi. Lokhu futhi kwenza kube nzima ukufinyelela ukugxila okuphelele ezimeni zokukhanya okuphansi noma uma isihloko sitholakala kancane.

1.2 Iintroducing the Light Field Camera Module

Ishadi lezi lukhuni lwekhamera lumele ubuchwepheshe obukhulu bokwakha. Luphula imikhawulo yesiko ngokuthwebula hhayi kuphela amandla kodwa futhi nendlela yokukhanya, kuvumela ukulungiswa kokugxila ngemva kokuthwebula. Le msebenzi emangalisayo ivumela abasebenzisi ukuthi bashintshe iphuzu lokugxila ngemva kokuthathwa kwesithombe, njengokuthi babe namandla okuphinda baphinde bakhethe indawo yokugxila ehlukile.

II. Iziqinisekiso Zobuchwepheshe beMojula yeKhamera yeMithala Yezibani

2.1 Ukuthwebula nokurekhoda Ulwazi Lwokukhanya

Ihlo lekhanda ikhamera module isebenzisa indlela ehlukile yokuthola ulwazi lokukhanya. Iqukethe i-micro lens array efakwe phakathi kwe-lens enkulu kanye nesensori. Lapho ukukhanya kungena kumoduli, ama-micro lenses ahlukanisa imisebe evela ezindaweni ezahlukene. I-lens ngayinye ikhipha ukukhanya endaweni ethile yesensori, ibamba kokubili amandla nokuhamba kokukhanya. Le datha ibhalwa njengendawo yokukhanya ye-4D, enezixhumanisi ezikhombisa indawo nokuhamba kwemisebe yokukhanya, ivumela imodyuli ukuthi igcine imephu ebanzi ye-ndawo yokukhanya.

2.2 Micro Lens Array Design

Ithala lens array iyingxenye ebalulekile kumamojuli wekhamera ye-light field. Iqukethe ama-lens amancane amaningi ahlale eduze. I-lens ngayinye isebenza njengohlelo lokuthwebula oluncane, ithwebula ingxenye yesigcawu ukusuka kokuthile. Ngokwenza kanjalo, i-array iqoqela ukukhanya kusuka ezindaweni ezahlukene, ikakhulukazi ikhetha i-light field. Le mklamo iqinisekisa ukuthi lapho ukukhanya kudlula, kuhlukaniswe ngokwendawo futhi kugxilwe ku-sensor, kulula ukuthwebula imininingwane yokukhanya enembile ebalulekile ekucubunguleni ngemva kokuthwebula nasekulungiseni ukugxila.

2.3 Isithombe Sokwakha Ialgorithimi

Ukuze kwakhiwe izithombe ezineziqondiso ezihlukene, imodyuli ithembele kumasu ahlakaniphile. Enye indlela evamile ihilela ukusebenzisa idatha ye-4D light field ethathwe ukuze kudalwe i-virtual pinhole array. Ngokwenza imifanekiso yezikhala ezihlukene ze-pinhole, i-algorithm ingashintsha kahle ibanga lokugxila. Iphatha ama-ray okukhanya athathwe ngalinye i-micro lens, ihlanganisa ulwazi oluvela ezicini eziningi ukuze ikhiqize isithombe esisha esinefokali efunwayo. Le nqubo ihilela ukubalwa okuyinkimbinkimbi ukuze kubhekwane nesixhumanisi nesivinini sama-ray okukhanya, kuqinisekisa ukuthi isithombe esakhiwe sikhanyisiwe futhi sinezincazelo ezicacile endaweni egxilile.

III. Ukuqhathanisa Nezithombe Zendabuko
