Iimodyuli zokulinganisa umgama welaser zizixhobo ezichanekileyo kakhulu ezisetyenziswa kakhulu kwiindawo ezifana nokuqhuba okuzenzakalelayo, iidrone, ukuzisebenzela kwemizi-mveliso, kunye neerobhothi. Umgaqo wokusebenza kwezi modyuli uhlala ubandakanya ukukhupha umqadi welaser kunye nokulinganisa umgama phakathi kwento kunye nesensor ngokufumana ukukhanya okubonakalayo. Phakathi kweeparamitha ezahlukeneyo zokusebenza kweemodyuli zokulinganisa umgama welaser, umahluko womqadi yinto ebalulekileyo echaphazela ngokuthe ngqo ukuchaneka kokulinganisa, uluhlu lokulinganisa, kunye nokukhetha iimeko zesicelo.
1. Ingcamango esisiseko yokwahlukana kwemisebe
Ukwahlukana kwemisebe kubhekisa kwi-engile apho umqadi welaser ukhula khona ngobukhulu obunqamlezileyo njengoko uhamba usiya kude ne-laser emitter. Ngamazwi alula, okukhona umahluko wemisebe uncinci, kokukhona umqadi welaser uxineneyo ngakumbi ngexesha lokusasazeka; ngokuchaseneyo, ukuhlukana kwemisebe kukhulu, kokukhona umqadi usasazeka ngokubanzi. Kwizicelo ezisebenzayo, ukuhlukana kwemisebe kudla ngokubonakaliswa ngee-engile (iidigri okanye ii-milliradians).
Ukwahlukana komqadi welaser kumisela ukuba usasazeka kangakanani kumgama othile, nto leyo echaphazela ubungakanani bendawo kwindawo ekujoliswe kuyo. Ukuba umahluko mkhulu kakhulu, umqadi uya kugubungela indawo enkulu kumgama omde, nto leyo enokunciphisa ukuchaneka kokulinganisa. Kwelinye icala, ukuba umahluko mncinci kakhulu, umqadi unokuba ugxile kakhulu kumgama omde, nto leyo eyenza kube nzima ukubonisa kakuhle okanye ukuthintela nokufunyanwa kwesignali ebonisiweyo. Ke ngoko, ukukhetha umahluko ofanelekileyo wemitha kubalulekile ekuchanekeni nasekusetyenzisweni koluhlu lwemodyuli yokulinganisa umgama welaser.
2. Impembelelo yokwahluka kweMisebe ekusebenzeni kweModyuli yokulinganisa umgama ngeLaser
Ukwahlukana kwemisebe kuchaphazela ngokuthe ngqo ukuchaneka kokulinganisa kwemodyuli yomgama welaser. Ukwahlukana kwemisebe emikhulu kubangela ubungakanani obukhulu bebala, okunokukhokelela ekukhanyeni okukhanyayo okusasazekileyo kunye nokulinganisa okungachanekanga. Kumgama omde, ubungakanani bebala elikhulu bunokwenza buthathaka ukukhanya okubonakalayo, okuchaphazela umgangatho wesignali ofunyenwe yi-sensor, ngaloo ndlela kwandisa iimpazamo zokulinganisa. Ngokwahlukileyo koko, ukwahlukana kwemisebe emincinci kugcina umsebe welaser ugxile kumgama omde, okubangela ubungakanani bebala obuncinci kwaye ngaloo ndlela ukuchaneka kokulinganisa okuphezulu. Kwizicelo ezifuna ukuchaneka okuphezulu, njengokuskena kwelaser kunye nendawo echanekileyo, ukwahlukana kwemisebe emincinci ngokubanzi lukhetho olukhethwayo.
Ukwahluka kwemitha kukwanxulumene kakhulu noluhlu lokulinganisa. Kwiimodyuli zomgama welaser ezinokwahluka kwemitha enkulu, umqadi welaser uya kusasazeka ngokukhawuleza kumgama omde, ubuthathaka bomqondiso obonakalisiweyo kwaye ekugqibeleni unciphise uluhlu lokulinganisa olusebenzayo. Ukongeza, ubungakanani obukhulu bendawo bunokubangela ukuba ukukhanya okubonisiweyo kuvele kwiindlela ezahlukeneyo, okwenza kube nzima ukuba isenzi sifumane ngokuchanekileyo uphawu oluvela kwithagethi, nto leyo echaphazela iziphumo zokulinganisa.
Kwelinye icala, umahluko omncinci wemitha unceda umqadi welaser uhlale uxineneyo, ukuqinisekisa ukuba ukukhanya okubonakalayo kuhlala kuqinile kwaye ngaloo ndlela kwandisa uluhlu lokulinganisa olusebenzayo. Ke ngoko, umahluko omncinci wemitha wemodyuli yokulinganisa umgama welaser, kokukhona uluhlu lokulinganisa olusebenzayo luhlala lukhula.
Ukukhethwa kokwahluka kwemitha kukwanxulunyaniswa kakhulu nemeko yokusetyenziswa kwemodyuli yokulinganisa umgama welaser. Kwiimeko ezifuna ukulinganisa okude nokuchaneka okuphezulu (njengokubona izithintelo ekuqhubeni ngokuzimela, iLiDAR), imodyuli enokwahluka kwemitha encinci idla ngokukhethwa ukuqinisekisa ukulinganiswa okuchanekileyo kumgama omde.
Kwimilinganiselo yomgama omfutshane, ukuskena, okanye ezinye iinkqubo zokwenza izinto ngokuzenzekelayo kwimizi-mveliso, imodyuli enomahluko omkhulu wemitha ingakhethwa ukwandisa indawo yokugubungela nokuphucula ukusebenza kakuhle kokulinganisa.
Ukwahluka kwemisebe kukwachatshazelwa ziimeko zokusingqongileyo. Kwiindawo ezintsonkothileyo ezineempawu ezicacileyo (ezifana nemigca yemveliso yemizi-mveliso okanye ukuskena izakhiwo), ukusasazeka komsebe welaser kunokuchaphazela ukubonakaliswa kunye nokwamkelwa kokukhanya. Kwiimeko ezinjalo, ukwahluka kwemisebe emikhulu kunokunceda ngokugubungela indawo enkulu, kwandisa amandla esignali efunyenweyo, kunye nokunciphisa ukuphazamiseka kokusingqongileyo. Kwelinye icala, kwiindawo ezicacileyo, ezingaphazanyiswanga, ukwahluka kwemisebe encinci kunokunceda ukugxila umlinganiselo kwindawo ekujoliswe kuyo, ngaloo ndlela kuncitshiswe iimpazamo.
3. Ukukhethwa kunye noYilo loKwahluka kweMisebe
Ukwahluka kwemisebe yemodyuli yokulinganisa umgama we-laser kudla ngokugqitywa luyilo lwe-laser emitter. Iimeko ezahlukeneyo zokusetyenziswa kunye neemfuno zikhokelela kwiinguqu kuyilo lokwahluka kwemisebe. Ngezantsi kukho iimeko ezininzi eziqhelekileyo zokusetyenziswa kunye nokukhetha kwazo ukwahluka kwemisebe okunxulumene nazo:
- Ukulinganisa Okuphezulu Nokuchaneka Okude:
Kwizicelo ezifuna umgama ochanekileyo nowokulinganisa okude (njengokulinganisa okuchanekileyo, i-LiDAR, kunye nokuqhuba ngokuzimela), kukhethwa umahluko omncinci wemitha ngokubanzi. Oku kuqinisekisa ukuba umqadi welaser ugcina ubungakanani obuncinci bebala kumgama omde, nto leyo ephucula ukuchaneka kokulinganisa kunye nomgama. Umzekelo, ekuqhubeni ngokuzimela, umahluko wemitha kwiinkqubo ze-LiDAR uhlala ungaphantsi kwe-1° ukuze kubonwe ngokuchanekileyo imiqobo ekude.
- Ukhuseleko Olukhulu Oluneemfuno Eziphantsi Zokuchaneka:
Kwiimeko apho kufuneka indawo enkulu yokugubungela, kodwa ukuchaneka kungabalulekile kangako (njengokufumaneka kwerobhothi kunye nokuskena okusingqongileyo), umahluko omkhulu wemitha udla ngokukhethwa. Oku kuvumela umqadi welaser ukuba ugubungele indawo ebanzi, kuphucula amandla okuva esi sixhobo, kwaye kusenze sifaneleke ukuskena ngokukhawuleza okanye ukufunyanwa kwendawo enkulu.
- Umlinganiselo woMgama oMfutshane ngaphakathi:
Kwimilinganiselo yangaphakathi okanye yomgama omfutshane, umahluko omkhulu wemitha unokunceda ukwandisa ukugqunywa komqadi welaser, kunciphisa iimpazamo zokulinganisa ngenxa yee-engile zokubonakalisa ezingafanelekanga. Kwiimeko ezinjalo, umahluko omkhulu wemitha unokuqinisekisa iziphumo zokulinganisa ezizinzileyo ngokwandisa ubungakanani bebala.
4. Isiphelo
Ukwahluka kwemitha yelaser yenye yezinto eziphambili ezichaphazela ukusebenza kweemodyuli zokulinganisa umgama welaser. Ichaphazela ngokuthe ngqo ukuchaneka kokulinganisa, uluhlu lokulinganisa, kunye nokukhetha iimeko zesicelo. Uyilo olufanelekileyo lokwahluka kwemitha yelaser lunokuphucula ukusebenza ngokubanzi kwemodyuli yokulinganisa umgama welaser, ukuqinisekisa uzinzo kunye nokusebenza kwayo kuzo zonke iinkqubo ezahlukeneyo. Njengoko iteknoloji yokulinganisa umgama welaser iqhubeka nokukhula, ukuphucula ukwahluka kwemitha yelaser kuya kuba yinto ebalulekileyo ekwandiseni uluhlu lwesicelo kunye nobuchule bokulinganisa kwezi modyuli.
