He pilikia kēia i loko o ka laulā o ka optics, nona ka wehewehe maʻamau i ka optics.ʻO ke kiʻi i hana ʻia ma ke kiʻi ʻana i ke kiʻi me ka pahupaʻikiʻi e hoʻololi ʻia.No ka laʻana, loaʻa iā mākou ka ʻike o ke kiʻi ʻana i nā kiʻi me nā kāmera maʻamau ma ka home.Aia kekahi ʻano lens i kapa ʻia ʻo "lens wide-angle", i kapa ʻia ʻo "fisheye lens" me ke aloha ʻole.Ke kiʻi ʻoe i ke kiʻi me kēia ʻano lens, e ʻike ʻoe ua piʻo ke kiʻi ma nā ʻaoʻao o ke kiʻi.Hoʻokumu ʻia kēia ʻano ma muli o ka "lens distortion".ʻO ka laʻana o ka "fisheye lens" no ka mea ʻo ka "fisheye lens" he lens me ka distortion nui.
He distortion ka lens, ʻo ka ʻokoʻa, ʻokoʻa ka distortion.No ka ʻōnaehana nānā ʻike, manaʻolana ʻia ʻo ka distortion lens i hoʻohana ʻia he liʻiliʻi loa.ʻO kēia ke kumu i ka wā e hana ai ka ʻōnaehana hihiʻo i ka ʻike, hana ʻia ia ma ke kiʻi i kiʻi ʻia e ke kāmela.Inā “kekee” ke kiʻi kiʻi o ka pahupaʻikiʻi, ʻaʻole "pololei" ka hopena o ka ʻike ʻana o ka ʻōnaehana - ʻo ia hoʻi, ʻaʻole pololei ka kukuna luna a kekee ke kukuna lalo.
ʻElua ala no ka ʻōnaehana hihiʻo e hoʻoponopono i ka distortion lens: ʻo ia hoʻi, e hoʻomaka mai ka lako kamepiula a i ʻole e hoʻomaka mai ka polokalamu.He maʻalahi ke ala e hoʻomaka ai mai ka hāmeʻa: e hoʻohana wale i kahi lens me ka liʻiliʻi.Ua kapa ʻia kēia ʻano lens he lens imaging telecentric, he kumukūʻai, ʻoi aku ma mua o 6 a i ʻole 7 manawa o ke kumu kūʻai o ka lens maʻamau.ʻO ka distortion o kēia ʻano lens aia ma lalo o 1%, a hiki i kekahi ke hiki i ka 0.1%.Hoʻohana ka hapa nui o nā ʻōnaehana ʻike makaʻala i kēia ʻano lens: ʻO ke ala ʻelua ʻo ka hoʻomaka ʻana mai ka polokalamu.I ka hana ʻana i ka "calibration camera", e hoʻohana i ka kiko kiko ma ka module calibration standard e helu ai.ʻO ke ʻano kikoʻī: ma hope o ka pau ʻana o ka "calibration camera", loaʻa ka nui o kēlā me kēia kiko i ka dot matrix e like me ke ana ʻike ʻia, a ʻo ka nui o nā kiko ma ka ʻaoʻao o ka dot matrix ʻo ia. kālailai ʻia.He okoa ka nui kiko.Hiki ke loaa ka ratio ma ka hoohalike ana, a o keia ratio ka distortion o ka lens.Me kēia ratio, hiki ke hoʻoponopono ʻia ka distortion i ke ana maoli.
