ʻO Sonar, Lidar, Radar/Optic kahe

No laila, inā ʻaʻole maikaʻi ka triangulation e ka satellite e pale aku i ka lepo, e hoʻāʻo kākou e "ʻike" pololei!

I kēia manawa, aia ma kahi o ʻekolu mau ʻenehana hoʻomaka i hoʻomākaukau ʻia e hiki ke hoʻouna i nā hōʻailona a ʻike i ka lōʻihi o ka lele ʻana: sonar, lidar a me radar module hiki ke hoʻohana ʻia i kēia manawa.

Eia nō naʻe, he mau nāwaliwali kēia mau sensor:

Nawaliwali 1: absorption

ʻAʻole lele wale kekahi mau ʻili.Hoʻopili nā pale a me nā kāpeti i nā hawewe kani ultrasonic, ʻeleʻele ka pena ʻeleʻele i ka lidar, a ʻo ka wai e hoʻopau i nā microwave.ʻAʻole hiki iā ʻoe ke holo i ka mea āu e ʻike ʻole ai.

Nawaliwali 2: keakea pae

Aia ka hōʻailona keakea ma waena o nā mea ʻike.He aha ka hopena inā hoʻohui ʻoe i nā mea ʻike like like?Pehea ʻoe e ʻike ai no kēia mea ʻike ka hōʻailona āu i ʻike ai?ʻO kahi mea ʻike hoʻokahi pono e hana i ka crosstalk mai iā ia iho a kali lōʻihi no ka nalo ʻana o ka leo.

Hiki ke "hoʻopili ʻia" nā hōʻailona (hoʻopili maoli ʻia) i ʻokoʻa kēlā me kēia hōʻailona, ​​akā hoʻonui kēia i ka paʻakikī o ka hāmeʻa.* * ʻO kahi hopena maikaʻi ʻo ka semi-randomize i ka hoʻolālā hōʻailona, ​​i ʻole e laka ʻia ka manawa a hoʻopunipuni mau ʻia e ka hōʻailona synchronization.

He ʻano ʻano ʻokoʻa ka sensor kahe opical, e hoʻohana ana i ka pahupaʻikiʻi e nānā i ka nui aʻe o ka mea i loko o ka lens (e hōʻike ana i ka piʻi wikiwiki ʻana o ka honua/pā), ʻoi aku ka liʻiliʻi (ke nalo ka mea keakea) a i ʻole ke ʻeke ʻaoʻao.ʻAʻole hoʻopilikia nā kāmeʻa i kekahi i kekahi e like me ka sonar.Inā akamai maoli ʻoe, hiki iā ʻoe ke koho i ka tilt a me nā waiwai 3D ʻē aʻe.

Loaʻa ka nāwaliwali o ka "absorption" i nā mea ʻike kahe o ka Optical.Pono ʻoe i kahi ʻili kikokikona maikaʻi no lākou e ʻike i ke kahe ʻana, e like me ka hiki ʻole i kā lākou ʻiole optical ke hana ma ke aniani.Ke lilo nei lākou i mea kaulana loa, no ka mea, ʻo ka streaming computing kahi mea hiki iā ʻoe ke hoʻokomo i loko o kahi FPGA a i ʻole kamepiula hoʻokomo wikiwiki.
