Amamojula okulinganisa ibanga le-laser angamathuluzi anembile kakhulu asetshenziswa kabanzi emikhakheni efana nokushayela okuzenzakalelayo, ama-drone, ukuzenzekela kwezimboni, kanye namarobhothi. Isimiso sokusebenza sala mamojula ngokuvamile sihilela ukukhipha umsebe we-laser nokulinganisa ibanga phakathi kwento kanye nenzwa ngokwamukela ukukhanya okubonakalayo. Phakathi kwamapharamitha ahlukahlukene okusebenza kwamamojula okulinganisa ibanga le-laser, ukuhlukahluka komsebe kuyisici esibalulekile esithinta ngqo ukunemba kokulinganisa, ububanzi bokulinganisa, kanye nokukhetha kwezimo zohlelo lokusebenza.
1. Umqondo Oyisisekelo Wokwehlukana Kwemisebe
Ukuhlukana kwemisebe kubhekisela ekhoneni lapho umsebe we-laser ukhula khona ngobukhulu obunqamulayo njengoba uhamba kude ne-laser emitter. Ngamagama alula, lapho ukuhlukana kwemisebe kuncane, kulapho umsebe we-laser uhlala ugxile khona ngesikhathi sokusabalala; ngokuphambene nalokho, lapho ukuhlukana kwemisebe kukhulu, kulapho umsebe usakazeka khona kakhulu. Ekusetshenzisweni okungokoqobo, ukuhlukana kwemisebe kuvame ukuvezwa ngama-engeli (amadigri noma ama-milliradian).
Ukuhlukana komsebe we-laser kunquma ukuthi usakazeka kangakanani ebangeni elithile, okuthinta usayizi wendawo entweni eqondiwe. Uma ukuhlukana kukhulu kakhulu, umsebe uzomboza indawo enkulu ebangeni elide, okunganciphisa ukunemba kokulinganisa. Ngakolunye uhlangothi, uma ukuhlukana kuncane kakhulu, umsebe ungase ugxile kakhulu ebangeni elide, okwenza kube nzima ukubonakalisa kahle noma kuvimbele ukwamukelwa kwesignali eboniswayo. Ngakho-ke, ukukhetha ukuhlukana komsebe ofanele kubalulekile ekunembeni nasekusetshenzisweni kwebanga lemodyuli yokulinganisa ibanga le-laser.
2. Umthelela Wokwehlukana Kwemisebe Ekusebenzeni Kwemojula Yokulinganisa Ibanga Le-Laser
Ukuhlukana kwemisebe kuthinta ngqo ukunemba kokulinganisa kwemojuli yebanga le-laser. Ukuhlukana kwemisebe emikhulu kuholela kusayizi omkhulu wendawo, okungaholela ekukhanyeni okukhanyayo okuhlakazekile kanye nokulinganisa okunganembile. Emabangeni amade, usayizi omkhulu wendawo ungenza buthaka ukukhanya okubonakalayo, kuthinte ikhwalithi yesignali etholwe yinzwa, ngaleyo ndlela kwandise amaphutha okulinganisa. Ngokuphambene nalokho, ukuhlukana kwemisebe emincane kugcina umsebe we-laser ugxile emabangeni amade, okuholela kusayizi omncane wendawo futhi ngaleyo ndlela kube nokunemba okuphezulu kokulinganisa. Ezinhlelweni zokusebenza ezidinga ukunemba okuphezulu, njengokuskena kwe-laser kanye nendawo eqondile, ukuhlukana kwemisebe emincane ngokuvamile kuyisinqumo esikhethwayo.
Ukuhlukana kwemisebe nakho kuhlobene eduze nobubanzi bokulinganisa. Kumamojula ebanga le-laser anokuhlukana kwemisebe emikhulu, umsebe we-laser uzosabalala ngokushesha emabanga amade, unciphise isignali eboniswayo futhi ekugcineni unciphise ububanzi bokulinganisa obusebenzayo. Ngaphezu kwalokho, usayizi omkhulu wendawo ungabangela ukukhanya okubonakalayo ukuthi kuvele ezindleleni eziningi, okwenza kube nzima ngenzwa ukuthola isignali ngokunembile kusuka ekuqondisweni, okuthinta imiphumela yokulinganisa.
Ngakolunye uhlangothi, ukuhlukana kwemisebe emincane kusiza umsebe we-laser ukuthi uhlale ugxilile, okuqinisekisa ukuthi ukukhanya okubonakalayo kuhlala kuqinile futhi ngaleyo ndlela kwandise ububanzi bokulinganisa obusebenzayo. Ngakho-ke, uma ukuhlukana kwemisebe kuncane kwemojuli yokulinganisa ibanga le-laser, kulapho ububanzi bokulinganisa obusebenzayo buvame ukwanda khona.
Ukukhethwa kokwehluka kwemishayo nakho kuhlobene kakhulu nesimo sokusetshenziswa kwemojuli yokulinganisa ibanga le-laser. Ezimweni ezidinga izilinganiso ezinde nezinembile (njengokutholwa kwezithiyo ekushayeleni okuzenzakalelayo, i-LiDAR), imojuli enokwehluka kwemishayo emincane ivame ukukhethwa ukuqinisekisa izilinganiso ezinembile emabangeni amade.
Ngezilinganiso zebanga elifushane, ukuskena, noma ezinye izinhlelo zokwenza izinto ngokuzenzakalela zezimboni, imodyuli enokwehluka okukhulu kwemisebe ingase ikhethwe ukwandisa indawo yokumboza nokuthuthukisa ukusebenza kahle kokulinganisa.
Ukuhlukana kwemisebe nakho kuthonywa yizimo zemvelo. Ezindaweni eziyinkimbinkimbi ezinezimpawu ezikhanyayo eziqinile (njengemigqa yokukhiqiza yezimboni noma ukuskena kwesakhiwo), ukusabalala kwemisebe ye-laser kungathinta ukukhanyiswa nokwamukelwa kokukhanya. Ezimweni ezinjalo, ukuhlukana kwemisebe emikhulu kungasiza ngokumboza indawo enkulu, kwandise amandla esignali etholakele, futhi kunciphise ukuphazamiseka kwemvelo. Ngakolunye uhlangothi, ezindaweni ezicacile, ezingavinjelwe, ukuhlukana kwemisebe emincane kungasiza ekugxiliseni isilinganiso esiqondisweni, ngaleyo ndlela kuncishiswe amaphutha.
3. Ukukhethwa Nokwakhiwa Kokwehlukana Kwemisebe
Ukuhlukana kwemisebe yemojuli yokulinganisa ibanga le-laser kuvame ukunqunywa ukwakheka kwe-laser emitter. Izimo ezahlukene zokusetshenziswa kanye nezidingo ziholela ekuhlukeni komklamo wokuhlukana kwemisebe. Ngezansi kunezimo eziningana ezivamile zokusetshenziswa kanye nokukhetha kwazo okuhlobene nokuhlukana kwemisebe:
- Ukunemba Okuphezulu kanye Nokulinganisa Okude:
Kuzinhlelo zokusebenza ezidinga kokubili ukunemba okuphezulu kanye namabanga amade okulinganisa (njengokulinganisa okunembile, i-LiDAR, kanye nokushayela okuzenzakalelayo), ukuhlukahluka okuncane kwemisebe kuvame ukukhethwa. Lokhu kuqinisekisa ukuthi umsebe we-laser ugcina usayizi omncane wendawo ebangeni elide, okuthuthukisa kokubili ukunemba kokulinganisa kanye nobubanzi. Isibonelo, ekushayeleni okuzenzakalelayo, ukuhlukahluka kwemisebe yezinhlelo ze-LiDAR kuvame ukugcinwa ngaphansi kuka-1° ukuze kutholakale ngokunembile izithiyo ezikude.
- Ukumbozwa Okukhulu Okunezidingo Eziphansi Zokunemba:
Ezimweni lapho kudingeka indawo enkulu yokumboza, kodwa ukunemba kungabalulekile kangako (njengokutholakala kwendawo yamarobhothi kanye nokuskena kwemvelo), ukuhlukahluka okukhulu kwemisebe kuvame ukukhethwa. Lokhu kuvumela umsebe we-laser ukumboza indawo ebanzi, kuthuthukisa amakhono okuzwa kwedivayisi, futhi kuyenze ifanelekele ukuskena okusheshayo noma ukutholwa kwendawo enkulu.
- Ukulinganisa Ibanga Elifushane Langaphakathi:
Ekulinganisweni kwangaphakathi noma kwebanga elifushane, ukuhlukana okukhulu kwemisebe kungasiza ekwandiseni ukumbozwa kwemisebe ye-laser, kunciphisa amaphutha okulinganisa ngenxa yama-engeli okubonisa angafanele. Ezimweni ezinjalo, ukuhlukana okukhulu kwemisebe kungaqinisekisa imiphumela yokulinganisa ezinzile ngokwandisa usayizi wendawo.
4. Isiphetho
Ukuhlukana kwemisebe kungenye yezinto ezibalulekile ezithinta ukusebenza kwamamojula okulinganisa ibanga le-laser. Kuthinta ngqo ukunemba kokulinganisa, ububanzi bokulinganisa, kanye nokukhethwa kwezimo zohlelo lokusebenza. Ukwakheka okufanele kokuhlukana kwemisebe kungathuthukisa ukusebenza okuphelele kwemojula yokulinganisa ibanga le-laser, kuqinisekise ukuzinza kwayo kanye nokusebenza kahle kuzo zonke izinhlelo zokusebenza ezahlukahlukene. Njengoba ubuchwepheshe bokulinganisa ibanga le-laser buqhubeka nokukhula, ukwenza ngcono ukuhlukana kwemisebe kuzoba yinto ebalulekile ekwandiseni ububanzi bokusetshenziswa kanye namakhono okulinganisa ala mamojula.
