Lub ntsiab Performance index ntawm LiDAR

LiDAR cov kev ua haujlwm tseem ceeb suav nrog laser wavelength, nrhiav tau ntau yam, Field of View (FOV), xws li qhov tseeb, qhov kev daws teeb meem, taw tes tus nqi, tus lej ntawm cov kab teeb, qib kev nyab xeeb, qhov ntsuas qhov ntsuas, IP ntsuas, lub zog, cov khoom siv hluav taws xob, laser emission hom (mechanical /solid-state), thiab lifespan. LiDAR qhov zoo yog pom tseeb hauv nws qhov kev tshawb pom dav dua thiab siab dua. Txawm li cas los xij, nws qhov kev ua tau zoo txo ​​qis hauv huab cua huab cua lossis haus luam yeeb, thiab nws cov ntaub ntawv khaws cia siab tuaj ntawm tus nqi ntau.

◼ Laser wavelength:

Feem ntau wavelengths rau 3D duab LiDAR yog 905nm thiab 1550nm.1550nm wavelength LiDAR sensorstuaj yeem ua haujlwm ntawm lub zog siab dua, txhim kho kev tshawb nrhiav ntau yam thiab nkag mus los ntawm nag thiab pos huab. Lub ntsiab kom zoo dua ntawm 905nm yog nws nqus los ntawm silicon, ua silicon-based photodetectors pheej yig dua li qhov xav tau rau 1550nm.
◼ Qib Kev Nyab Xeeb:

Qib kev nyab xeeb ntawm LiDAR, tshwj xeeb yog tias nws ua tau raws liChav kawm 1 tus qauv, nyob ntawm lub laser tso zis hwj chim tshaj nws lub sij hawm ua hauj lwm, xav txog lub wavelength thiab lub sij hawm ntawm laser hluav taws xob.
Detection Range: LiDAR qhov ntau yog cuam tshuam nrog kev cuam tshuam ntawm lub hom phiaj. High reflectivity tso cai rau ntev nrhiav kom tau deb, thaum qis reflectivity shortens qhov ntau.
◼ FOV:

LiDAR's Field of View suav nrog ob qho tib si kab rov tav thiab ntsug. Mechanical rotating LiDAR systems feem ntau muaj 360-degree kab rov tav FOV.
◼ Angular Resolution:

Qhov no suav nrog kev daws teeb meem ntsug thiab kab rov tav. Kev ua tiav kev daws teeb meem kab rov tav yog qhov yooj yim vim yog lub tshuab tsav tsheb, feem ntau ncav cuag 0.01-degree. Vertical daws teeb meem muaj feem xyuam rau qhov loj geometric thiab kev teeb tsa ntawm emitters, nrog kev daws teeb meem feem ntau ntawm 0.1 txog 1 degree.
◼ Point Rate:

Tus naj npawb ntawm cov ntsiab lus laser tso tawm ib ob los ntawm LiDAR system feem ntau yog li ntawm kaum rau ntau pua txhiab tus ntsiab lus hauv ib ob.
◼Number of Beams:

Multi-beam LiDAR siv ntau lub laser emitters teem vertically, nrog lub cev muaj zog rotation tsim ntau yam scanning beams. Tus naj npawb tsim nyog ntawm kab teeb nyob ntawm qhov yuav tsum tau ua ntawm kev ua cov algorithms. Ntau kab teeb muab cov lus piav qhia txog ib puag ncig, uas tuaj yeem txo cov kev xav tau algorithmic.
◼Output Parameters:

Cov no suav nrog txoj haujlwm (3D), ceev (3D), kev taw qhia, lub sijhawm teev (hauv qee qhov LiDAR), thiab kev cuam tshuam ntawm kev cuam tshuam.
◼ Lifespan:

Cov tshuab tig LiDAR feem ntau kav ntev li ob peb txhiab teev, thaum lub xeev LiDAR muaj peev xwm kav ntev txog 100,000 teev.
◼ Laser Emission Hom:

Ib txwm LiDAR siv cov qauv kev sib hloov tshuab, uas yooj yim rau hnav thiab tsim kua muag, txwv txoj sia.Solid-stateLiDAR, suav nrog Flash, MEMS, thiab Phased Array hom, muaj ntau dua durability thiab efficiency.
