I-Sonar, i-lidar, i-radar/i-optical flow

Ngakho-ke, uma unxantathu ngesathelayithi akuyona indlela enhle yokugwema umhlabathi, ake sizame "ukukubona" ​​ngqo!

Njengamanje, kukhona okungenani ubuchwepheshe obuthathu obenziwe ngomumo obuhlukahlukene obungadlulisa amasignali futhi bubone ukuthi kuthatha isikhathi esingakanani ukugxuma: i-sonar, i-lidar nemojula ye-radar konke kungasetshenziswa manje.

Nokho, lezi zinzwa zinobuthakathaka:

Ubuthakathaka 1: ukumuncwa

Ezinye izindawo azibhampisi. Amakhethini nokhaphethi bamunca amagagasi akhanyayo, upende omnyama udonsa i-lidar, futhi amanzi amunca ama-microwave. Awukwazi ukubalekela into ongayiboni.

Ubuthakathaka 2: ukuphazamiseka kwesigaba

Kukhona ukuphazamiseka kwesignali phakathi kwezinzwa. Kwenzekani uma uhlanganisa izinzwa eziningi ezifanayo? Wazi kanjani ukuthi isignali oyitholile ingeyale nzwa? Ngisho nenzwa eyodwa kufanele ibhekane ne-crosstalk ngokwayo futhi ilinde isikhathi eside ngokwanele ukuze i-echo inyamalale.

Amasignali "angabhalwa ngekhodi" (ngokuyisisekelo abethelwe) ukuze isignali ngayinye ihluke, kodwa lokhu kwandisa ubunkimbinkimbi bedivayisi. * * Isixazululo esihle ukwenza i-semi-randomize uhlelo lwesignali, ukuze isikhathi singakhiyiwe futhi sizohlala sikhohliswa isignali yokuvumelanisa.

Inzwa yokugeleza kwe-Optical iyindlela ehlukile, esebenzisa ikhamera ukuze ibone ukuthi into ekulensi iba nkulu yini (okukhombisa ukuthi umhlabathi/udonga lukhuphuka ngokushesha), lube luncane (uma isithiyo sinyamalala) noma islayida emaceleni. Amakhamera awaphazamisi njengama-sonar. Uma uhlakaniphe ngempela, ungakwazi ukulinganisa ukutsheka nezinye izici ze-3D.

Izinzwa ze-Optical flow zisenobuthakathaka "bokumunca". Udinga indawo ebhalwe kahle ukuze babone ukugeleza, njengoba nje negundane labo elibonayo lingakwazi ukusebenza engilazini. Ziya ngokuya ziduma, ngoba ukusakaza ngekhompyutha manje sekuyinto ongayifaka ku-FPGA noma ikhompyutha eshumekwe ngokushesha.
