Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, ubuchwepheshe bokuthola i-laser bungene emikhakheni eminingi futhi busetshenziswe kabanzi. Ngakho-ke, yimaphi amanye amaqiniso abalulekile mayelana nobuchwepheshe bokuthola uhla lwe-laser okufanele siwazi? Namuhla, ake sabelane ngolwazi oluyisisekelo mayelana nalobu buchwepheshe.
1.Kwaqala Kanjani Ukutholwa Kwelaser?
Iminyaka yawo-1960 yabona ukukhula kobuchwepheshe be-laser rangefinding. Lobu buchwepheshe ekuqaleni bebuthembele ekushayeni kwe-laser eyodwa futhi basebenzise indlela ye-Time of Flight (TOF) yokulinganisa ibanga. Endleleni ye-TOF, imojula ye-laser rangefinder ikhipha i-laser pulse, ebuye ibuyiswe into eqondiwe futhi ithathwe umamukeli wemojuli. Ngokwazi isivinini esingaguquki sokukhanya kanye nokulinganisa ngokunembile isikhathi esisithathayo ukuze i-laser pulse ihambe iye kulokho okuqondiwe nokubuyela emuva, ibanga eliphakathi kwento nesitholi sebanga lingabalwa. Ngisho nanamuhla, eminyakeni engama-60 kamuva, ubuchwepheshe obuningi bokulinganisa amabanga busathembela kulo mgomo osuselwe ku-TOF.
2.Iyini i-Multi-Pulse Technology ku-Laser Rangefinding?
Njengoba ubuchwepheshe bokulinganisa ishayela elilodwa bukhula, ukuhlola okwengeziwe kwaholela ekusetshenzisweni kokuhlolwa kobuchwepheshe bokulinganisa amapulse amaningi. Ubuchwepheshe be-Multi-pulse, obusekelwe endleleni ye-TOF ethembeke kakhulu, ilethe izinzuzo ezinkulu kumadivayisi aphathekayo ezandleni zabasebenzisi bokugcina. Emasosheni, ngokwesibonelo, izinto eziphathwa ngesandla ezisetshenziselwa ukuqondisa iziqondiso zibhekana nenselele engenakugwenywa yokundindizela okuncane kwezandla noma ukuzamazama. Uma ukundindizela okunjalo kubangela ukuthi ishayela elilodwa ligeje ithagethi, imiphumela yokulinganisa enembile ayikwazi ukutholwa. Kulo mongo, ubuchwepheshe be-multi-pulse bubonisa izinzuzo zabo eziwujuqu, njengoba buthuthukisa kakhulu amathuba okushaya okuqondiwe, okubalulekile kumadivayisi aphathwa ngesandla namanye amasistimu amaningi eselula.
3.Isebenza Kanjani I-Multi-Pulse Technology ku-Laser Rangefinding?
Uma kuqhathaniswa nobuchwepheshe bokulinganisa ishayela elilodwa, izitholi ze-laser ezisebenzisa ubuchwepheshe bokulinganisa ama-pulse amaningi azikhiphi nje ukushaya kwe-laser okukodwa kokulinganisa ibanga. Esikhundleni salokho, baqhubeka bethumela uchungechunge lwama-laser pulses amafushane kakhulu (ahlala ebangeni le-nanosecond). Isikhathi esiphelele sokulinganisa salawa ma-pulses sisukela kuma-millisecond angama-300 kuye kwangama-800, kuye ngokusebenza kwemojula ye-laser rangefinder esetshenzisiwe. Uma la ma-pulses esefinyelele lapho kuqondiwe khona, aboniswa emuva kumamukeli ozwela kakhulu kusitholi sebanga le-laser. Umamukeli ube eseqala ukwenza isampula yama-echo pulses atholiwe futhi, ngokusebenzisa ama-algorithms okulinganisa anembe kakhulu, angakwazi ukubala inani elithembekile lebanga, ngisho noma inani elilinganiselwe kuphela lama-laser abonisiwe pulses abuyiswayo ngenxa yokunyakaza (isb, ukuzamazama okuncane okuvela ekusetshenzisweni okubanjwe ngesandla. ).
I-4.I-Lumispot Ikuthuthukisa Kanjani Ukunemba Kokuthola Ibanga Le-Laser?
- Indlela Yokulinganisa Yokushintsha Okuhlukanisiwe: Ukukala Okunembayo ukuze Kuthuthukiswe Ukunemba
I-Lumispot isebenzisa indlela yokulinganisa yokushintsha ehlukaniswe ngezigaba egxile esilinganisweni esinembayo. Ngokulungiselela ukwakheka kwendlela yokubona kanye nama-algorithms okucubungula isignali athuthukisiwe, kuhlanganiswe nokuphuma kwamandla aphezulu kanye nezici ze-pulse ende ye-laser, i-Lumispot ingena ngempumelelo ekuphazamisekeni komkhathi, iqinisekisa imiphumela yokulinganisa ezinzile nenembile. Lobu buchwepheshe busebenzisa isu lokuthola ibanga lemvamisa ephezulu, ngokuqhubekayo likhipha ama-laser pulses amaningi futhi liqongelela amasignali e-echo, licindezela ngempumelelo umsindo nokuphazamiseka. Lokhu kuthuthukisa kakhulu isilinganiso sesignali-kuya-nomsindo, kuzuza isilinganiso esinembile sebanga. Ngisho nasezindaweni eziyinkimbinkimbi noma ezinokwehluka okuncane, indlela yokulinganisa yokushintsha ehlukanisiwe iqinisekisa imiphumela enembayo nezinzile, ikwenze kube ubuchwepheshe obubalulekile bokuthuthukisa ukunemba kokulinganisa.
- I-Dual Threshold Compensation Yokunemba Kokuthola Ububanzi: Ukulinganisa Okubili Kokunemba Okudlulele
I-Lumispot futhi isebenzisa isikimu sokulinganisa se-dual-threshold esinomshini wokulinganisa okabili oyinhloko. Isistimu iqala ngokusetha ama-threshold amasignali amabili ahlukene ukuze ithwebule amaphuzu amabili esikhathi esibalulekile wesignali ye-echo yalowo oqondiwe. Lawa maphuzu esikhathi ahluka kancane ngenxa yemikhawulo ehlukene, kodwa lo mehluko uba ukhiye wokunxephezela amaphutha. Ngesilinganiso sesikhathi esinembayo nokubala, isistimu ingakwazi ukubala ngokunembile umehluko wesikhathi phakathi kwalawa maphoyinti esikhathi amabili bese ishuna umphumela wangempela wokuthola uhla, ithuthukise ngokuphawulekayo ukunemba kokuthola ububanzi.
5.Ingabe Amamojula Okunembe Kakhulu, Obude Obude beLaser Athatha Ivolumu Enkulu?
Ukuze kwenziwe amamojula we-laser rangefinder asetshenziswe kabanzi futhi kalula, amamojula anamuhla e-laser rangefinder aguquke abe amafomu ahlangene futhi amahle kakhulu. Isibonelo, i-LSP-LRD-01204 laser rangefinder yeLumispot ibonakala ngosayizi wayo omncane ngendlela emangalisayo (11g kuphela) nesisindo esilula, kuyilapho igcina ukusebenza okuzinzile, ukumelana nokushaqeka okuphezulu, kanye nokuphepha kwamehlo Kwekilasi I. Lo mkhiqizo ubonisa ukulingana okuphelele phakathi kokuphatheka nokuqina futhi uye wasetshenziswa kabanzi emikhakheni efana nokukhomba nokuthola uhla, ukubeka i-electro-optical positioning, ama-drones, izimoto ezingenamuntu, amarobhothi, izinhlelo zokuthutha ezihlakaniphile, izinto ezihlakaniphile, ukukhiqizwa kokuphepha, nokuphepha okukhaliphile. Idizayini yalo mkhiqizo ikhombisa ngokugcwele ukuqonda okujulile kweLumispot kwezidingo zabasebenzisi kanye nokuhlanganiswa okuphezulu kokuqanjwa kabusha kwezobuchwepheshe, okuwenza ugqame emakethe.
