Tsanangura muchidimbu tekinoroji yekuona yeLiDAR
Lidar (Kuona Nekutarisa Kwechiedza) inoshandisa daro rema point clouds/pixels kuti iongorore chimiro chetatu-dimensional (3D) chezvinangwa, uye yakakurumidza kukura mumaonero asina kurongeka enzvimbo dzakadai sekutyaira kwega, kufamba kwemarobhoti, kugadzira mapoinzi, uye kuona kure.
Kusiyana netekinoroji yekufungidzira ye3D isingashande iyo inogona kungodzoreredza ruzivo rwe3D rwenzvimbo dzemwenje dziri munzvimbo, LiDAR inogona kuwana ruzivo rwe3D rwenzvimbo yakapoteredza uye kusanganisa maalgorithms akadai sekugadzira point cloud, kusefa ruzha, kunyoresa kurongeka, uye tsananguro yechinhu kuti inzwisise nzvimbo. Zvichibva munzira dzakasiyana dzekuona chiedza, LiDAR iripo inogona kukamurwa kuita kuona zvakananga uye kuona kwakabatana.
Kuona zvakananga uchishandisa pulsed light uye kuona echo intensity yechinangwa kuburikidza ne photodetector. LiDAR yakajairika isinganzwisisike tekinoroji inochinja nguva yekubhururuka (TOF) iyo inonyanya kushandisa maapplication akawanda nekuda kwekugadzirisa kwayo hardware yakakura uye nzira dzekugadzirisa masaini. Zvisinei, huwandu hwekuona uye resolution yeTOF LiDAR zvinogumira pakushanda kwemudziyo wekuona fotouye simba guru relaser inoputika, uye chiratidzo chayo che echo chinogonawo kukanganiswa nechiedza chezuva kana imwe radar systemlasermatanda.
Kusiyana neizvi, kuona kwakabatana uchishandisa tekinoroji yekusanganisa optical pakati pe echo beam ne local oscillator beam kunogona kudzivirira kupindira kwechiedza chezvakatipoteredza uye kuvandudza system signal-to-noise ratio. Traditional LiDAR inonyanya kuvimba nesimba, 3D coordinates, kana kumhanya kwemifananidzo, uye kusakwana kweruzivo kunoita kuti LiDAR idzi dzisazivikanwe uye dzisarongwe. Kunyanya kune zvinangwa zvine maumbirwo akasiyana-siyana, pane kusanzwisisika pakuona gore renzvimbo pane chinangwa, zvichikonzera kusava nechokwadi mukuzivikanwa kwechimiro che3D chechinangwa.
Imwe nzira inoshanda ndeyekushandisa polarization component yechiedza, iyo inogona kuvandudza zvinobudirira chokwadi chemakore/mapikiseli enzvimbo yekunanga. Nekuongorora kudyidzana kuripo pakati pe polarized light nezvinhu, ruzivo rwechimiro uye kuumbwa kwechinangwa zvinogona kufungidzirwa. Polarization coherent LiDAR inobatanidza nzira dzepamusoro kubva kumatunhu akasiyana-siyana akadai se optics, mechanics, control, uye electronic information, ichifukidza dzidziso huru dzakadai sekuona ruzivo, beam scanning, uye polarization imaging.
