Bhalisela kwiMedia yethu yeNtlalo ukuze ufumane iPosi ngokukhawuleza

Itekhnoloji ye-LiDAR (i-Light Detection kunye ne-Ranging) ibone ukukhula okuqhumayo, ngokuyintloko ngenxa yezicelo zayo ezibanzi. Inika ulwazi olunamacala amathathu malunga nehlabathi, oluyimfuneko ekuphuhliseni iirobhothi kunye nokufika kokuqhuba ngokuzimeleyo. Ukutshintsha ukusuka kwiinkqubo ze-LiDAR ezixabisa oomatshini ukuya kwizisombululo ezinexabiso elithe kratya zithembisa ukuzisa inkqubela phambili ebalulekileyo.

Ukusetyenziswa komthombo wokukhanya kweLidar kwimiboniso ephambili ezi:umlinganiselo wobushushu osasaziweyo, iimoto LIDAR, kwayeimephu yoluvo olukude, cofa ukufunda ngakumbi ukuba unomdla.

Iimpawu eziphambili zokuSebenza ze-LiDAR

Iiparamitha eziphambili ze-LiDAR zibandakanya ubude be-laser, uluhlu lokubona, uMmandla wokuJonga (i-FOV), ukuchaneka okuphakathi, isisombululo se-angular, isantya samanqaku, inani leemitha, inqanaba lokhuseleko, iiparitha zokuphuma, ukulinganisa kwe-IP, amandla, umbane wokubonelela, imo ye-laser emission /imeko-eqinile), kunye nexesha lokuphila. Izibonelelo ze-LiDAR ziyabonakala kuluhlu lwayo olubanzi lokuchongwa kunye nokuchaneka okuphezulu. Nangona kunjalo, ukusebenza kwayo kuncipha kakhulu kwimozulu embi kakhulu okanye kwiimeko zomsi, kwaye umthamo wayo ophezulu wokuqokelela idatha ufika kwiindleko ezinkulu.

◼ Laser Wavelength:

Ubude obuqhelekileyo be-3D yokucinga i-LiDAR yi-905nm kunye ne-1550nm.I-1550nm yobude bobude boluvo lwe-LiDARinokusebenza kumandla aphezulu, iphucula uluhlu lokubona kunye nokungena ngemvula kunye nenkungu. Olona ncedo luphambili lwe-905nm kukufunxwa kwayo ngesilicon, isenza ii-photodetectors ezise-silicon zingabizi kakhulu kunezo zifunekayo kwi-1550nm.
◼ Inqanaba loKhuseleko:

Inqanaba lokhuseleko le-LiDAR, ngakumbi ukuba liyadibanaImigangatho yeklasi yoku-1, kuxhomekeke kumandla okukhutshwa kwelaser ngexesha lawo lokusebenza, ngokuqwalasela ubude be-wavelength kunye nobude bemitha yelaser.
Uluhlu lokuchongwa: Uluhlu lwe-LiDAR lunxulumene nokubonakala kwethagethi. Ukubonakala okuphezulu kuvumela ukubonwa komgama omde, ngelixa ukubonakalisa okuphantsi kunciphisa uluhlu.
◼ FOV:

Intsimi yeLiDAR yokuJonga ibandakanya zombini ii-engile ezithe tye kunye nezithe nkqo. Iinkqubo ze-LiDAR ezijikelezayo zoomatshini zihlala zine-360-degree ethe tyaba ye-FOV.
◼ Isisombululo se-Angular:

Oku kuquka izisombululo ezithe nkqo nezithe tye. Ukufikelela kwisisombululo esiphezulu esithe tye ngokuthe ngqo ngenxa yeendlela eziqhutywa yimoto, zihlala zifikelela kumanqanaba e-0.01-degree. Isisombululo esithe nkqo sinxulumene nobukhulu bejometri kunye nolungiselelo lwee-emitters, kunye nezigqibo eziqhelekileyo phakathi kwe-0.1 ukuya kwi-1 degree.
◼ Inqanaba leNqaku:

Inani lamanqaku e-laser akhutshwa ngesekhondi yinkqubo ye-LiDAR ngokubanzi ukusuka kumashumi ukuya kumakhulu amawaka amanqaku ngomzuzwana.
Inani leMiqadi:

I-LiDAR ye-Multi-beam isebenzisa ii-laser emitters ezininzi ezicwangciswe ngokuthe nkqo, kunye nokujikeleza kwemoto kudala imiqadi yokuskena emininzi. Inani elifanelekileyo lemiqadi lixhomekeke kwiimfuno ze-algorithms yokucubungula. Imiqadi eyongezelelekileyo ibonelela ngenkcazo egcweleyo yokusingqongileyo, enokunciphisa iimfuno ze-algorithmic.
Iziphumo:

Ezi ziquka indawo (3D), isantya (3D), isalathiso, isitampu sexesha (kwezinye ii-LiDAR), kunye nokubonakaliswa kwemiqobo.
◼ Ubomi:

Oomatshini abajikelezayo i-LiDAR ihlala ingamawaka ambalwa eeyure, ngelixa iLiDAR eqinile inokuhlala ukuya kuthi ga kwiiyure ezili-100,000.
◼ Indlela yokukhupha iLaser:

I-LiDAR yesiNtu isebenzisa ulwakhiwo olujikelezayo ngoomatshini, oluthanda ukunxiba kunye nokukrazula, ukunciphisa ixesha lokuphila.Ilizwe eliqinileyoI-LiDAR, kubandakanya iFlash, i-MEMS, kunye neentlobo ze-Phased Array, ibonelela ngokuzinzileyo kunye nokusebenza kakuhle.

Iindlela zokukhupha iLaser:

Iinkqubo ze-laser LIDAR zemveli zihlala zisebenzisa izakhiwo ezijikelezayo ngoomatshini, ezinokuthi zikhokelele ekunxityweni nasekuphileni okulinganiselweyo. Izixokelelwano ze-laser ye-solid-state radar zinokuhlelwa ngokweendidi ezintathu eziphambili: I-Flash, i-MEMS, kunye noluhlu lwezigaba. I-Flash laser radar igubungela yonke indawo yokujonga kwi-pulse enye ukuba nje kukho umthombo wokukhanya. Emva koko, isebenzisa iXesha leFlight (ToF) indlela yokufumana idatha efanelekileyo kunye nokuvelisa imephu yeethagethi ezijikeleze i-laser radar. Irada ye-laser ye-MEMS ilula ngokwesakhiwo, ifuna kuphela umqadi welaser kunye nesipili esijikelezayo esifana negyroscope. I-laser ijoliswe kwesi sipili esijikelezayo, esilawula ulwalathiso lwelaser ngokujikeleza. Inqanaba lerada yelaser isebenzisa i-microarray eyenziwe zii-eriyali ezizimeleyo, eyivumela ukuba isasaze amaza erediyo kulo naliphi na icala ngaphandle kwesidingo sokujikeleza. Ilawula nje ixesha okanye uluhlu lweempawu ukusuka kwi-eriyali nganye ukwalathisa umqondiso kwindawo ethile.
