Sonar, lidar, radar/optical flow

Naizvozvo, kana triangulation nesatellite isiri nzira yakanaka yekudzivisa pasi, ngatiedzei "kuona" zvakananga!

Parizvino, pane anokwana matatu akagadzirira-akagadzirwa tekinoroji anogona kufambisa masaini uye kuona kuti zvinotora nguva yakareba sei kubhuroka: sonar, lidar uye radar module zvese zvinogona kushandiswa izvozvi.

Nekudaro, ma sensors aya ane utera:

Kushaya simba 1: kutorwa

Dzimwe nzvimbo hadzina kubhuroka.Maketeni nemakapeti anotora masaisai e ultrasonic, pendi yakasviba inotora lidar, uye mvura inotora microwaves.Iwe haugone kutiza pane zvausingaoni.

Utera 2: kupindira kwechikamu

Pane kukanganiswa kwechiratidzo pakati pezvinzwa.Chii chinoitika kana iwe ukaisa akawanda akafanana sensors pamwechete?Unoziva sei kuti chiratidzo chawaona ndeche sensor iyi?Kunyangwe sensor imwe chete inofanirwa kubata neiyo crosstalk kubva pachayo uye kumirira kwenguva yakakwana kuti echo iparare.

Zviratidzo zvinogona "kuvharirwa" (chaizvo zvakavharidzirwa) kuitira kuti chiratidzo chimwe nechimwe chive chakasiyana, asi izvi zvinowedzera kuoma kwechigadzirwa.* * Mhinduro yakanaka ndeyekuita semi-randomize chirongwa chechiratidzo, kuitira kuti nguva irege kuvharwa uye inogara ichinyengerwa nechiratidzo chekuyananisa.

Optical flow sensor inzira yakasiyana, inoshandisa kamera kuona kana chinhu chiri mulenzi chiri kukura (zvichiratidza kuti pasi/madziro ari kusimuka nekukurumidza), diki (apo chipingamupinyi chanyangarika) kana kutsvedza nedivi.Makamera haapindirane kune mumwe sesonar.Kana iwe wakanyatso hungwaru, unogona kufungidzira tilt uye zvimwe 3D zvivakwa.

Optical flow sensors ichine "absorption" kushaya simba.Iwe unoda yakanaka yakadhindwa nzvimbo kuti vaone kuyerera, sekufanana nembeva yavo yemaziso isingashande pagirazi.Ivo vari kuramba vachizivikanwa, nekuti kutenderera komputa chave chinhu chaunogona kuisa muFPGA kana komputa yakamisikidzwa nekukurumidza.
