Ua hoʻomohala nā mea noiʻi mai ka National University of Singapore a me Yonsei University (Korea) i kahi ala no ka ʻike ʻana i nā kiʻi paʻi huna i loko o ka hale me ka hoʻohana ʻana i kahi kelepona maʻamau i lako me kahi sensor ToF (Time of flight). Ua ʻike ʻia i kēia manawa hiki ke kūʻai ʻia kahi kāmela huna no kahi liʻiliʻi ma mua o hoʻokahi kālā a ʻo ia mau kāmela he 1-2 millimeters ka nui, ʻoi aku ka paʻakikī o ka loaʻa ʻana i loko o ka hale. Ma South Korea, ʻoi aku ma mua o 6800 mau hanana e pili ana i ka hoʻokomo ʻana i nā kāmela huna i loko o nā lumi hōkele a i ʻole nā lumi ʻauʻau i hoʻopaʻa ʻia i loko o ka makahiki.
ʻO ke ʻano LAPD (Laser-Assisted Photography Detection) i manaʻo ʻia e nā mea noiʻi e hiki ai ke ʻike i nā kāmela huna me ka hoʻohana ʻana i nā smartphones hou i hoʻolako ʻia me kahi sensor hohonu (ToF), i hoʻohana ʻia e koho i ka mamao o nā mea i ka wā e kālele ana i ke kāmela a me nā noi hoʻonui ʻia. ʻO nā hiʻohiʻona o nā smartphones e hoʻohana ana i kēlā mau mea naʻau e pili ana i ka Samsung S20 a me Huawei P30 Pro. Hoʻokumu ka mea ʻike i ka palapala ʻāina hohonu ma ka nānā ʻana i nā wahi a puni me ka laser a me ka helu ʻana i ka mamao e pili ana i ka lohi o ka hōʻea ʻana o ke kukui i ʻike ʻia.
Hoʻokumu ʻia ke ʻano no ka ʻike ʻana i nā kāmela huna ma ka ʻike ʻana i nā anomalies i ka hoʻomālamalama laser o nā lens a me nā lens, e hana ana i nā kikoʻī kikoʻī ma ka palapala ʻāina hohonu. ʻIke ʻia nā anomali me ka hoʻohana ʻana i kahi algorithm aʻo mīkini e hiki ke hoʻokaʻawale i ka ʻōlinolino kikoʻī o ka kamera. Manaʻo nā mea kākau o ka noiʻi e hoʻolaha i nā noi i mākaukau no ka Android platform ma hope o ka hoʻoponopono ʻana i kekahi mau pilikia me nā palena API.
ʻO ka nui o ka manawa i koi ʻia e nānā i kahi lumi i manaʻo ʻia he 30-60 kekona. Ma kahi hoʻokolohua i hana ʻia me 379 mau mea manawaleʻa, ʻike ʻia nā kāmela huna e hoʻohana ana i ke ʻano LAPD i 88.9% o nā hihia. No ka hoʻohālikelike, ʻo 46% wale nō o nā mea hoʻokolohua i hiki ke ʻike i nā kāmela ma ka maka, a ʻo ka maikaʻi o ka hoʻohana ʻana i ka mea ʻike hōʻailona K18 kūikawā he 62.3% a me 57.7%, ma muli o ke ʻano scanning i koho ʻia. Ua hōʻike pū ke ʻano LAPD i ka haʻahaʻa haʻahaʻa haʻahaʻa - 16.67% me 26.9%/35.2% no K18 a me 54.9% no ka huli maka.
ʻO ka pololei o ka ʻike ʻana i ka LAPD e pili ana i ka pahupaʻikiʻi huna e komo ana i ke kihi ʻike 20-degere o ka mea ʻike a aia ma kahi mamao maikaʻi loa mai ka mea ʻike (inā kokoke loa ia, pohihihi ke aniani mai ke kāmela, a inā mamao loa ia. hele aku, nalowale). No ka hoʻomaikaʻi ʻana i ka pololei, ua manaʻo ʻia e hoʻohana i nā sensor me ka hoʻonā kiʻekiʻe (i nā smartphones i loaʻa i nā mea noiʻi, ʻo ka hoʻonā ʻana o ka sensor ToF ʻo 320 × 240, ʻo ia hoʻi ka nui o ka anomaly i ke kiʻi he 1-2 pixels wale nō) a me ka hohonu. kikoʻī (i kēia manawa he 8 wale nō no kēlā me kēia pae hohonu pixel).
ʻO nā ʻano hana ʻē aʻe no ka loiloi ʻana i ka hele ʻana o kahi pahupaʻikiʻi huna e pili ana i nā mea loiloi uila uila, ka mea e hoʻoholo ai i ka hele ʻana o ke kahe wikiō ma luna o kahi pūnaewele uea, a me nā scanner radiation electromagnetic.
