USonar, i-lidar, i-radar / optical flow

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

Njengamanje, okungenani kukhona ubuchwepheshe obukhulu obukhulu obunenziwe obuhamba phambili obungadlulisela amasiginali futhi ubone ukuthi kuthatha isikhathi esingakanani ukushaya imodyuli:

Kodwa-ke, lezi zinzwa zinobuthakathaka:

Ubuthakathaka 1: Ukutholwa

Ezinye izindawo azikhohlisi. Amakhethini namakhaphethi amunca amagagasi e-ultrasonic, upende omnyama uthatha i-lidar, namanzi amunca ama-microwaves. Awukwazi ukubalekela lokho ongakuboni.

Ubuthakathaka 2: Ukuphazanyiswa kwesigaba

Kukhona ukuphazamiseka kwesiginali phakathi kwezinzwa. Kwenzekani lapho ubeka izinzwa eziningi ezifanayo ndawonye? Wazi kanjani ukuthi isibonakaliso ositholile singele nzwa? Ngisho inzwa eyodwa kufanele abhekane ne-crosstalk ngokwayo futhi alinde isikhathi eside ngokwanele ukuthi i-echo inyamalale.

Amasiginali angaba "afakwe" (okubhalwe ngokuyisisekelo) ukuze isinali ngalinye lihlukile, kepha lokhu kwandisa ubunzima bedivayisi. * * Isixazululo esihle ukuhlukanisa uhlelo lwesiginali, ukuze isikhathi singakhiyiwe futhi kuzohlala kukhohliswa yisiginali yokuvumelanisa.

I-Optical Flow Sensor iyindlela ehlukile, esebenzisa ikhamera ukubona ukuthi ngabe into esele lens iyakhula (okukhombisa ukuthi umhlabathi / udonga lukhuphuka ngokushesha), luncane (lapho isithiyo siphela) Amakhamera awaphazamisi omunye nomunye njengoSonar. Uma uhlakaniphile ngempela, ungalinganisa ukugcotshwa nezinye izakhiwo ze-3D.

Izinzwa zokugeleza ze-Optical zisenazo "ukumuncwa" ubuthakathaka. Udinga indawo enhle ebekiwe ukuze ubone ukugeleza, njengoba igundane labo lokubona alikwazi ukusebenza ngengilazi. Baya ngokuya bathandwa kakhulu, ngoba ukusakazwa kwekhompyutha manje sekuyinto ongayifaka kwi-FPGA noma kwikhompyutha eshumekiwe esheshayo.
