Ntev ntev 3D kev kos duab tau mus txog ib lub cim khoom cim

Cov kws tshawb nrhiav tau tsim lub laser lub koob yees duab kaw lus kom sau cov duab thaij duab siab siab 3D ntawm cov khoom, txij li ib mais (3000 feet) deb.

Cov txheej txheem muaj npe Time-of-Flight (ToF) qhov tob tob, raws li lub sijhawm nws siv rau lub teeb uas tawm ntawm lub laser mus ncig rov qab mus rau nws qhov chaw, tom qab bouncing tawm ntawm cov khoom thaij duab.

Cov kws tshawb nrhiav tau sim lub koob yees duab ntawm lawv tus kheej, los ntawm kev deb ntawm 910 meters. Lub lasers lub voos ntev ua rau nws zoo rau lub qhov muag.

Txog tam sim no, kev ncua ntev 3D kev ntsuas pom tau raug txwv heev

Cov cuab yeej thev naus laus zis ntawm no zoo ib yam li radar, tab sis ua rau siv lub teeb ci, tsis txhob siv microwaves. Rau daim phiaj qhia tawm cov khoom lossis chaw sim hauv 3D, cov kws tshawb fawb ua haujlwm ua lub ntsej muag laser thiab ntsuas ntev li cas nws siv rau lub teeb rov qab.

ToF qhov tob tob uas twb tau ua lawm thov nyob rau hauv tshuab kev pom kev thiab cov tshuab kev lag luam rau lub zog tsheb.

Txog tam sim no tab sis, cov thaj tsam npog tau luv heev. Tsis tas li, ToF cov khoom siv muaj teeb meem nrog ntau thaj chaw uas tsis cuam tshuam infrared teeb zoo.

Cov kws tshawb fawb los ntawm Edinburg, Scotland tau tsis ntev los no hais txog cov kev ua tsis tiav no, thiab tshaj tawm lawv cov kev tshwm sim hauv Optical Society cov ntawv xov xwm thoob ntiaj teb, Optics nthuav qhia.

Millimeter nplai precision dhau kev nrug deb

Led coj los ntawm Gerald Buller, tus xibfwb ntawm Heriot-Watt University hauv Edinburgh, ib pab neeg tshawb nrhiav tau sau cov ncauj lus kom pom lub koob npe duab 3D ntawm cov khoom, txij li ib mais deb.

Lawv lub koob yees duab system nrawm nrawm tsawg-powered laser kab teeb, dhau mus kev deb. Nws mam li khaws cov teeb xa rov qab, thiab cov phiaj xwm txhua tus neeg yees duab ncig mus ncig rau lub sijhawm ntawm cov lej, pixel-los-pixel.

Raws li txwv tsis pub dhau lub tshuab ua kom tob tshaj plaws, qhov no siv ntev ntev dua lub ntsej muag laser (ncig 1560 nanometers), uas pab kom kaw qhov ntau dua ntawm textures, xws li cov lus ntawm khaub ncaws.

Cov nthwv dej ntev dua, ntawm ntau dua 1550 nanometers, muaj qhov zoo dua ntawm huab cua, uas txhais tau tias lawv mus nrawm dua, thiab lawv lub teeb liab tau yooj yim dua los nrhiav, sawv ntawm qib suab hnub ci. Ob qho ntawm cov yam no ua rau thaj chaw augmented txog li ib mais.

Lwm qhov zoo ntawm lub nthwv dej yog tias nws yog muaj kev nyab xeeb rau lub qhov muag, yog siv thaum qis zog.

Txawm hais tias nws tuaj yeem paub qhov txawv khaub ncaws, lub koob yees duab tsis tuaj yeem ua rau tib neeg lub ntsej muag tseem, vim qhov tseeb tias tawv nqaij nqus tau lub teeb yooj yim. Txawm li cas los xij, cov tawv nqaij qhov kev coj ua zoo dua qub thaum tawm hws.

Dhau li ntawm qhov pom lub ntsej muag, lub koob yees duab koob yees duab tuaj yeem siv rau kev saib pom hauv kev nyuaj pom, lossis zoo li Gerald Buller qhia, tshuaj xyuas kev noj qab haus huv ntawm cov dav hlau, kuaj xyuas qhov muaj feem yuav phom sij, los ntawm kev ntsuas cov kev hloov pauv ntawm geological, lossis txhim kho daim phiaj qhia dej hiav txwv.
