Hoʻolauna

Mai ka hopena o nā makahiki 1960 a me nā makahiki 1970, ua hoʻololi ʻia ka hapa nui o nā ʻōnaehana kiʻi lewa kuʻuna e ka lewa a me ka aerospace electro-optical a me nā ʻōnaehana ʻike uila.ʻOiai e hana nui ana nā kiʻi lewa kuʻuna ma ka nalu ʻike-māmā, ʻo nā ʻōnaehana ʻike mamao o ka ea a me ka honua e hoʻopuka i ka ʻikepili kikohoʻe e uhi ana i ke kukui ʻike ʻia, ʻike ʻia ka infrared, thermal infrared, a me ka microwave spectral regions.He kōkua mau nā ʻano wehewehe ʻike kuʻuna ma ke kiʻi lewa.Eia nō naʻe, uhi ʻia ka ʻike mamao i kahi ākea o nā noi, me nā hana ʻē aʻe e like me ka hoʻohālikelike ʻana o nā waiwai i manaʻo ʻia, nā ana kikoʻī o nā mea, a me ka nānā ʻana i nā kiʻi kikohoʻe no ka ʻohi ʻike.

ʻO ka ʻike mamao, e pili ana i nā ʻano āpau o nā ʻenehana ʻike lōʻihi ʻole pili, he ʻano hana e hoʻohana ai i ka electromagnetism e ʻike, hoʻopaʻa a ana i nā ʻano o kahi pahuhopu a ua manaʻo mua ʻia ka wehewehe ʻana i nā makahiki 1950.ʻO ke kahua o ka ʻike mamao a me ka palapala ʻāina, ua māhele ʻia i 2 mau ʻano ʻike: active a passive sensing, kahi o Lidar sensing e hana nei, hiki ke hoʻohana i kona ikehu ponoʻī e hoʻokuʻu i ka mālamalama i ka pahu hopu a ʻike i ke kukui i ʻike ʻia mai ia mea.

 ʻIke a me ka hoʻohana ʻana i ka Lidar Active

ʻO ka Lidar (ʻike kukui a me ka pae) he ʻenehana e ana i ka mamao ma muli o ka manawa o ka hoʻokuʻu ʻana a me ka loaʻa ʻana o nā hōʻailona laser.I kekahi manawa hoʻohana ʻia ʻo Airborne LiDAR me ka nānā ʻana i ka laser airborne, ka palapala ʻāina, a i ʻole LiDAR.

He palapala kahe maʻamau kēia e hōʻike ana i nā ʻanuʻu koʻikoʻi o ka hoʻoili ʻikepili kiko i ka wā o ka hoʻohana ʻana iā LiDAR.Ma hope o ka hōʻiliʻili ʻana i nā hoʻonohonoho (x, y, z), ʻo ka hoʻokaʻawale ʻana i kēia mau kiko hiki ke hoʻomaikaʻi i ka maikaʻi o ka hāʻawi ʻana a me ka hana ʻana.Ma waho aʻe o ka hana geometric o nā helu LiDAR, pono nō hoʻi ka ʻike ikaika mai ka manaʻo LiDAR.

Ma nā noi ʻike mamao a me ka palapala palapala ʻāina, loaʻa iā LiDAR ka pono kūʻokoʻa o ka loaʻa ʻana o nā ana pololei ʻoi aku ka kūʻokoʻa o ka lā a me nā hopena ʻē aʻe.Aia ʻelua ʻāpana ʻōnaehana ʻike mamao maʻamau, kahi mākaʻikaʻi laser a me kahi mea ʻike ana no ka hoʻonohonoho ʻana, hiki ke ana pololei i ke kaiapuni ʻāina i 3D me ka ʻole o ka geometric distortion no ka mea ʻaʻohe kiʻi kiʻi (ua kiʻi ʻia ka honua 3D i ka mokulele 2D).
