Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, ubuchwepheshe bokuthola ulwazi nge-laser buye bangena emikhakheni eminingi futhi busetshenziswa kabanzi. Ngakho-ke, yimaphi amaqiniso abalulekile mayelana nobuchwepheshe bokuthola ulwazi nge-laser okumele siwazi? Namuhla, ake sabelane ngolwazi oluyisisekelo mayelana nalobu buchwepheshe.
1. Kwaqala Kanjani Ukuqoqwa Kwe-Laser Rangefinding?
Iminyaka yawo-1960 yabona ukwanda kobuchwepheshe bokuthola ububanzi be-laser. Lobu buchwepheshe ekuqaleni babuthembele ku-laser pulse eyodwa futhi basebenzise indlela ye-Time of Flight (TOF) yokulinganisa ibanga. Endleleni ye-TOF, i-laser rangefinder module ikhipha i-laser pulse, ebuye iboniswe emuva yinto eqondiwe bese ibanjwa yi-receiver ye-module. Ngokwazi ijubane lokukhanya elingaguquki kanye nokulinganisa ngokunembile isikhathi esithathwa yi-laser pulse ukuya ekuqondisweni nasekubuyeni, ibanga phakathi kwento kanye ne-rangefinder lingabalwa. Ngisho nanamuhla, eminyakeni engama-60 kamuva, ubuchwepheshe obuningi bokulinganisa ibanga busathembele kulesi simiso esisekelwe ku-TOF.
2. Iyini i-Multi-Pulse Technology ku-Laser Rangefinding?
Njengoba ubuchwepheshe bokulinganisa i-single-pulse bukhula, ukuhlola okwengeziwe kwaholela ekusetshenzisweni kokuhlola ubuchwepheshe bokulinganisa i-multi-pulse. Ubuchwepheshe be-multi-pulse, obusekelwe endleleni ye-TOF ethembeke kakhulu, bulethe izinzuzo ezinkulu kumadivayisi aphathekayo ezandleni zabasebenzisi bokugcina. Ngokwesibonelo, amasosha, amadivayisi aphathwa ngesandla asetshenziselwa ukukhomba amathegethi abhekene nenselele engenakugwenywa yokuthuthumela okuncane kwesandla noma ukunyakazisa. Uma ukuzamazama okunjalo kubangela ukuthi i-single pulse iphuthelwe yithagethi, imiphumela yokulinganisa enembile ayikwazi ukutholakala. Kulesi simo, ubuchwepheshe be-multi-pulse bubonisa izinzuzo zabo eziyinhloko, njengoba buthuthukisa kakhulu amathuba okushaya ithagethi, okubalulekile kumadivayisi aphathwa ngesandla nakwezinye izinhlelo eziningi zeselula.
3. Busebenza Kanjani Ubuchwepheshe Be-Multi-Pulse ku-Laser Rangefinding?
Uma kuqhathaniswa nobuchwepheshe bokulinganisa i-single-pulse, ama-laser rangefinder asebenzisa ubuchwepheshe bokulinganisa i-multi-pulse awakhiphi i-laser pulse eyodwa kuphela yokulinganisa ibanga. Esikhundleni salokho, athumela njalo uchungechunge lwama-laser pulse amafushane kakhulu (ahlala ebangeni le-nanosecond). Isikhathi sokulinganisa esiphelele sala ma-pulse sisukela kuma-millisecond angu-300 kuya kwangu-800, kuye ngokusebenza kwemoduli ye-laser rangefinder esetshenzisiwe. Uma la ma-pulse efika ekuhlosweni, abuyiselwa emuva kumukeli ozwela kakhulu ku-laser rangefinder. Umamukeli ube eseqala ukusampula ama-echo pulses atholiwe futhi, ngokusebenzisa ama-algorithms okulinganisa anembile kakhulu, angabala inani lebanga elithembekile, noma ngabe inani elilinganiselwe lama-laser pulse abonisiwe abuyiselwa ngenxa yokunyakaza (isb., ukuthuthumela okuncane okuvela ekusetshenzisweni okubanjwe ngesandla).
4. I-Lumispot Ikuthuthukisa Kanjani Ukunemba Kokuqoqwa Kwe-Laser?
- Indlela Yokulinganisa Ukushintsha Okuhlukaniswe Ngezigaba: Ukulinganisa Okunembile Ukuze Kuthuthukiswe Ukunemba
I-Lumispot isebenzisa indlela yokulinganisa ukushintshana okuhlukaniswe ngezigaba egxile ekulinganisweni okunembile. Ngokwenza ngcono ukwakheka kwendlela yokukhanya kanye nama-algorithms okucubungula amasignali athuthukile, kuhlanganiswe nokukhishwa kwamandla aphezulu kanye nezici zokushaya kwenhliziyo okude kwe-laser, i-Lumispot ingena ngempumelelo ekuphazamisekeni komoya, iqinisekisa imiphumela yokulinganisa ezinzile nenembile. Lobu buchwepheshe busebenzisa isu lokuthola ububanzi obuphezulu, bukhipha njalo ama-laser pulse amaningi futhi buqongelela amasignali e-echo, bucindezela ngempumelelo umsindo kanye nokuphazamiseka. Lokhu kuthuthukisa kakhulu isilinganiso sesignali kuya komsindo, kufezwe ukulinganisa ibanga okunembile. Ngisho nasezindaweni eziyinkimbinkimbi noma ngokushintsha okuncane, indlela yokulinganisa ukushintshana okuhlukaniswe ngezigaba iqinisekisa imiphumela enembile nezinzile, okwenza kube ubuchwepheshe obubalulekile bokuthuthukisa ukunemba kokulinganisa.
- Isinxephezelo Semiphetho Emibili Sokunemba Kokuthola Ibanga: Ukulinganiswa Okubili Kokunemba Okukhulu
I-Lumispot iphinde isebenzise uhlelo lokulinganisa olunezinhlangothi ezimbili olunendlela yokulinganisa ekabili eyinhloko. Uhlelo luqala lusethe imingcele emibili ehlukene yesignali ukuze lubambe amaphuzu amabili esikhathi abalulekile esignali ye-echo yethagethi. La maphuzu esikhathi ahluka kancane ngenxa yemingcele ehlukene, kodwa lo mehluko uba yisihluthulelo sokukhokha amaphutha. Ngokulinganisa isikhathi okunembe kakhulu nokubala, uhlelo lungabala ngokunembile umehluko wesikhathi phakathi kwala maphuzu amabili esikhathi futhi lulungise umphumela wokuqala wokuthola ububanzi, okuthuthukisa kakhulu ukunemba kokuthola ububanzi.
5. Ingabe Amamojula Okuqopha Ububanzi Be-Laser Anembe Kakhulu, Athatha Umthamo Omkhulu?
Ukuze kwenziwe amamojula we-laser rangefinder asetshenziswe kabanzi futhi kalula, amamojula we-laser rangefinder anamuhla aguqukele ezinhlotsheni ezincane nezinhle kakhulu. Isibonelo, i-laser rangefinder ye-Lumispot ye-LSP-LRD-01204 iphawuleka ngobukhulu bayo obuncane kakhulu (11g kuphela) kanye nesisindo esilula, ngenkathi igcina ukusebenza okuzinzile, ukumelana nokushaqeka okuphezulu, kanye nokuphepha kwamehlo kwe-Class I. Lo mkhiqizo ubonisa ibhalansi ephelele phakathi kokuthwala nokuqina futhi usetshenziswe kabanzi emikhakheni efana nokuthola i-target kanye ne-rangefinding, ukubeka i-electro-optical, ama-drone, izimoto ezingenamuntu, amarobhothi, izinhlelo zokuhamba ezihlakaniphile, izinto zokuthutha ezihlakaniphile, ukukhiqizwa kokuphepha, kanye nokuphepha okuhlakaniphile. Umklamo walo mkhiqizo ubonisa ngokugcwele ukuqonda okujulile kwe-Lumispot ngezidingo zomsebenzisi kanye nokuhlanganiswa okuphezulu kokusungula izinto ezintsha kwezobuchwepheshe, okwenza kube yinto evelele emakethe.
