Indlela I-Laser Range isebenza ngayo

Ngokomgomo oyisisekelo, kunezinhlobo ezimbili zezindlela ze-laser ezisukela: isikhathi-sokundiza (TOF) okusukela kanye non-time-of-flight ranges.Kukhona i-pulsed laser esukela kanye ne-laser esekwe esigabeni esukela ekuhambeni kwesikhathi sokundiza.

I-Pulse ranging iyindlela yokulinganisa eyaqala ukusetshenziswa emkhakheni wokuhlola kanye nokwenza imephu ngobuchwepheshe be-laser.Ngenxa yokuthi i-laser divergence angle incane, ubude be-laser pulse bufushane ngokwedlulele, futhi amandla asheshayo makhulu ngokwedlulele, ngakho-ke ingafinyelela ibanga elide kakhulu.Ngokuvamile, inhloso yokubambisana ayisetshenziswa, kodwa ukubonakaliswa okusabalalisayo kwesignali yokukhanya ngethagethi elinganisiwe kusetshenziselwa ukukala ibanga.

Umgomo wendlela yokulinganisa ipulsed uqondwa kahle.Iwashi elinemvamisa ephezulu lishayela ikhawunta ukubala isikhathi phakathi kokuthumela nokwamukela ama-pulses, okwenza isikhathi sewashi lokubala sibe sincane kakhulu kunesikhathi esiphakathi kokuthumela nokwamukela ama-pulses ukuze kuqinisekiswe ukunemba Okwanele, ngakho le ndlela yokuhlukanisa ifanele isikhathi eside- isilinganiso sebanga.

I-engeli yokukhishwa kwe-pulsed laser incane, amandla agxile emkhathini, futhi amandla asheshayo makhulu.Ngokusebenzisa lezi zici, kungenziwa ama-laser rangefinders aphakathi nendawo nakude, ama-lidar, njll.Njengamanje, i-pulsed laser rangeing isetshenziswa kakhulu ekukaleni isimo sezwe kanye ne-geomorphological, ukuhlola indawo, ukukala ukwakhiwa kobunjiniyela, ukukalwa kobude bendiza, ukugwenywa kwesithiyo sethrafikhi kanye nokuhlela, ukulinganisa ibanga lezimboni nezinye izici zobuchwepheshe.

Ukulinganisa kwe-laser yesigaba kuwukusebenzisa imvamisa yebhendi yomsakazo ukulinganisa ubude be-laser beam nokukala ukubambezeleka kwesigaba okukhiqizwa ukukhanya okuguquguqukayo ukuya emuva naphambili emugqeni wokulinganisa, bese uguqula ibanga elimelwe ukulibaziseka kwesigaba ngokuya kubude begagasi bokukhanya okushintshiwe.Okusho ukuthi, isikhathi esidingekayo ukuze ukukhanya kuhambe uye emuva naphambili emgqeni wokuhlola silinganiswa ngendlela engaqondile.Isigaba se-laser esukela ngokuvamile sisetshenziswa emkhakheni wokunemba ukuhluka.Ngenxa yokunemba kwayo okuphezulu, ngokuvamile ngohlelo lwamamilimitha, ukuze kuboniswe isignali ngempumelelo futhi kukhawulelwe ithagethi elinganiselwe endaweni ethile ehambisana nokunemba kwethuluzi, le divayisi ehlukahlukene ifakwe isibonisi esibizwa ngokuthi i-cooperative target.ipuleti.

Ububanzi be-laser yesigaba ngokuvamile bufanele ukukalwa kwebanga elifushane nelimaphakathi, futhi ukunemba kokulinganisa kungafinyelela kumamilimitha.Kubuye kube indlela enembayo ephezulu kakhulu njengamanje.Ukulinganisa kwesigaba kuwukulinganisa ubukhulu bokukhanya begagasi lokukhanya elikhishiwe ngesignali eshintshiwe, nokulinganisa ngokungaqondile isikhathi ngokulinganisa umehluko wesigaba, okunzima kakhulu kunokulinganisa ngokuqondile isikhathi sokuya nokubuya.

Uma ufuna ukwazi ulwazi oluthe xaxa lwezobuchwepheshe kanye nemikhiqizo ehlobene ne-laser esukela, sicela usithinte.
