He aha ka Lens Fisheye a me nā ʻano o nā hopena Fisheye

A aniani maka iʻaHe aniani ākea loa ia, i ʻike ʻia hoʻi he aniani panoramic. Manaʻo nui ʻia he aniani maka iʻa kahi aniani me ka lōʻihi o ke kikowaena o 16mm a i ʻole ka lōʻihi o ke kikowaena pōkole, akā i ka ʻenekinia, ʻo kahi aniani me ka laulā kihi nānā ʻana ma mua o 140 degere ua kapa ʻia he aniani maka iʻa. I ka hana maoli, aia kekahi mau aniani me nā kihi nānā e ʻoi aku a hiki paha i 270 degere. ʻO ka aniani maka iʻa kahi hui kukui anti-telephoto me ka nui o ka distortion barela. ʻO ka aniani mua o kēia aniani e puka parabolically ana i mua, a ua like ke ʻano me ka maka o ka iʻa, no laila ka inoa "lens maka iʻa", a ua like kona hopena ʻike me ka iʻa e nānā ana i nā mea ma luna o ka wai.

ʻO ka aniani maka iʻa

Hilinaʻi ka aniani maka iʻa i ka hoʻokomo ʻana i kahi nui o ka distortion barela e loaʻa ai kahi kihi nānā nui. No laila, koe wale nō ka mea ma waenakonu o ke kiʻi, ʻo nā ʻāpana ʻē aʻe e pono ai ke laina pololei he mau distortions, kahi e alakaʻi ai i nā kapu he nui i kāna noi. No ka laʻana, ma ke kahua o ka palekana, hiki i kahi aniani maka iʻa ke pani i nā aniani maʻamau he nui e nānā i kahi ākea. ʻOiai hiki i ke kihi nānā ke hiki i 180º a ʻoi aku paha, ʻaneʻane ʻaʻohe kihi make no ka nānā ʻana. Eia naʻe, ma muli o ka distortion o ke kiʻi, paʻakikī ke ʻike ʻia ka mea e ka maka kanaka, kahi e hoʻemi nui ai i ka hiki ke nānā; ʻO kekahi laʻana ma ke kahua o ka robotics, pono nā robots automated e hōʻiliʻili i ka ʻike kiʻi o nā hiʻohiʻona a puni a ʻike iā lākou e hana i nā hana like.

Inā heaniani maka iʻai hoʻohana ʻia, hiki ke hoʻonui ʻia ka pono o ka hōʻiliʻili ʻana ma 2-4 mau manawa, akā ʻo ka aberration e paʻakikī ai ka ʻike ʻana i ka polokalamu. No laila pehea mākou e ʻike ai i ke kiʻi mai ka lens fisheye? Hāʻawi ʻia kahi algorithm e ʻike ai i nā kūlana o nā mea i loko o ke kiʻi. Akā he paʻakikī hoʻi ke hoʻomaopopo i ka ʻike ʻana i nā kiʻi paʻakikī ma muli o ka paʻakikī o ka computational o ka polokalamu. No laila, ʻo ke ʻano maʻamau i kēia manawa ʻo ka hoʻopau ʻana i ka distortion i loko o ke kiʻi ma o kahi moʻo o nā hoʻololi ʻana, i mea e loaʻa ai kahi kiʻi maʻamau a laila ʻike iā ia.

Nā kiʻi maka iʻa i hoʻoponopono ʻole ʻia a hoʻoponopono ʻia

ʻO ka pilina ma waena o ka pōʻai kiʻi a me ke sensor penei:

ʻO ka pilina ma waena o ka pōʻai kiʻi a me ka sensor

I kinohi,nā aniani maka iʻaua hoʻohana wale ʻia i ke kiʻi ʻana ma muli o ko lākou ʻano nani kūikawā ma muli o ka distortion barela a lākou e hana ai i ke kaʻina hana kiʻi. I nā makahiki i hala iho nei, ua hoʻohana nui ʻia ka hoʻohana ʻana o ka lens maka iʻa ma ke kahua o ke kiʻi ākea, ka pūʻali koa, ka nānā ʻana, ka hoʻohālike panoramic, ka projection spherical a pēlā aku. Ke hoʻohālikelike ʻia me nā lens ʻē aʻe, loaʻa i ka lens maka iʻa nā pono o ke kaumaha māmā a me ka liʻiliʻi.
