A lens ya fisheyendi lens lalikulu kwambiri, lomwe limadziwikanso kuti lens panoramic. Nthawi zambiri zimaganiziridwa kuti mandala okhala ndi kutalika kwa 16mm kapena lalitali lalifupi kwambiri ndi lens eyeye, koma mu engineering, mandala okhala ndi ma angle osiyanasiyana opitilira madigiri 140 onse pamodzi amatchedwa lens ya fisheye. M'zochita, palinso magalasi okhala ndi ngodya zowonera zomwe zimapitilira kapena kufika madigiri 270. Lens ya fisheye ndi gulu lowala la anti-telephoto lomwe lili ndi kupotoza kwa migolo yambiri. Diso lakutsogolo la mandalawa limatuluka kutsogolo, ndipo mawonekedwe ake ndi ofanana ndi diso la nsomba, chifukwa chake amatchedwa "nsomba ya fisheye", ndipo mawonekedwe ake amafanana ndi a nsomba yomwe imayang'ana zinthu pamwamba pamadzi.
Lens ya fisheye
Lens ya fisheye imadalira kuwonetsa mochita kupanga kuchuluka kwa mbiya kusokonekera kuti mupeze mbali yayikulu yowonera. Choncho, kupatula chinthu chapakati pa chithunzicho, mbali zina zomwe ziyenera kukhala mizere yowongoka zimakhala ndi zolakwika zina, zomwe zimapangitsa kuti zikhale zoletsedwa zambiri pakugwiritsa ntchito. Mwachitsanzo, pankhani ya chitetezo, lens ya fisheye imatha kulowa m'malo mwa magalasi wamba angapo kuti iwunikire mosiyanasiyana. Popeza mbali yowonera imatha kufika 180º kapena kupitilira apo, palibenso mbali yakufa yowunikira. Komabe, chifukwa cha kusokonezeka kwa chithunzicho, chinthucho n'chovuta kudziwika ndi diso la munthu, zomwe zimachepetsa kwambiri mphamvu yowunika; Chitsanzo china ndi cha maloboti, maloboti odzipangira okha amafunikira kuti atole zambiri zazithunzi zozungulira ndikuwazindikira kuti achitepo kanthu.
Ngati alens ya fisheyekugwiritsidwa ntchito, kusonkhanitsa bwino kumatha kuonjezeredwa ndi nthawi 2-4, koma kusokoneza kumapangitsa kuti pulogalamuyo ikhale yovuta kuzindikira. Ndiye timazindikira bwanji chithunzicho kuchokera ku lens ya fisheye? Algorithm imaperekedwa kuti izindikire malo a zinthu zomwe zili pachithunzichi. Koma zimakhalanso zovuta kuzindikira kuzindikira kwazithunzi zovuta chifukwa chazovuta zamapulogalamu. Choncho, njira yodziwika bwino tsopano ndiyo kuthetsa kupotoza kwa fano kupyolera muzosintha zambiri, kuti mupeze chithunzi chodziwika bwino ndikuchizindikira.
Zithunzi za Fisheye zosakonzedwa ndikukonzedwa
Ubale pakati pa chozungulira chazithunzi ndi sensa ndi motere:
Mgwirizano wapakati pazithunzi zozungulira ndi sensa
Poyamba,ma lens a fisheyeankangogwiritsidwa ntchito pojambula chifukwa cha kukongola kwawo kwapadera chifukwa cha kupotoza kwa mbiya komwe amapanga panthawi yojambula. M'zaka zaposachedwa, kugwiritsa ntchito ma lens a fisheye kwakhala kukugwiritsidwa ntchito kwambiri pojambula m'mbali zambiri, zankhondo, zowunikira, zowonera panoramic, projekiti yozungulira ndi zina zotero. Poyerekeza ndi magalasi ena, lens ya fisheye ili ndi ubwino wake wopepuka komanso wocheperako.
