Daim Ntawv Thov Ntawm Laser Modules hauv Kev Tsav Tsheb Tsav Tsheb

Daim ntawv thov ntawmLaser Modulesnyob rau hauv lub teb ntawm autonomous tsav tsheb yog heev nthuav thiab tseem ceeb. Ib qho ntawm cov thev naus laus zis tseem ceeb rau kev tsav tsheb tsis muaj tsheb yog ib puag ncig kev nkag siab, thiab qhov no yog thaj chaw tseem ceeb ntawm lidar. Los ntawm kev tsim qauv ib puag ncig siv lidar, lub tsheb tsis muaj kev tsav tsheb tuaj yeem ntes cov teeb meem ntawm txoj kev thiab kwv yees lawv cov kev txav mus los kom muaj kev ceeb toom ntxov lossis kev zam.

Tib lub sijhawm, lidar tseem ua lub luag haujlwm tseem ceeb hauv kev tso tsheb thiab kev taw qhia. Nws tuaj yeem pab cov tsheb autonomous ua qhov chaw ua haujlwm siab thiab npaj txoj hauv kev. Tsis tas li ntawd, raws li SLAM (Simultaneous Localization and Mapping) thev naus laus zis, lidar kuj tseem tuaj yeem pab tsim cov duab qhia tseeb thiab ua haujlwm ntawm lub sijhawm tiag tiag.

Nyob rau hauv cov nqe lus ntawm kev tswj tsheb, laser modules tuaj yeem ua tiav kev tswj xyuas cov tsheb tsis muaj zog los ntawm cov ntaub ntawv tau txais. Thaum muaj kev cuam tshuam los ze, lub laser module tuaj yeem tshaj tawm lus ceeb toom los txhim kho kev nyab xeeb ntawm kev tsav tsheb.

Txawm li cas los xij, txawm hais tias daim ntawv thov ntawm laser modules nyob rau hauv lub tshav pob ntawm autonomous tsav tsheb muaj ntau yam zoo, xws li high precision, muaj zog real-time kev ua tau zoo, thiab dav adaptability, nws kuj ntsib ib co kev cov nyom, xws li tus nqi siab, complex technology, thiab ib puag ncig cuam tshuam. . Tshwj xeeb, muaj cov teeb meem xws li kev ruaj ntseg nyob rau hauv lub ntsej muag ntawm cov huab cua sib txawv thiab hnyav ib puag ncig, kev txheeb xyuas qhov tseeb ntawm cov khoom nyob deb, me me sensor loj, thiab tswj cov nqi tsim khoom loj.

Daim ntawv thov ntawm laser modules hauv kev tsav tsheb tsis siv neeg
A. Ib puag ncig kev nkag siab: Ib puag ncig kev ua qauv yog ua los ntawm lidar kom paub txog kev ua haujlwm xws li kev ntsuas qhov teeb meem thiab ntsuas qhov deb.
Laser modules tau siv dav hauv kev tsav tsheb, uas ib puag ncig kev nkag siab yog qhov tseem ceeb. Kev ua qauv ib puag ncig los ntawm lidar tuaj yeem paub txog kev ua haujlwm xws li kev ntsuas qhov teeb meem thiab ntsuas qhov deb. Tsis tas li ntawd, lidar tuaj yeem ua qhov chaw ua haujlwm siab thiab npaj txoj hauv kev. Ntxiv mus, thaum muaj kev cuam tshuam los ze, lub laser module tuaj yeem tshaj tawm lus ceeb toom los txhim kho kev nyab xeeb ntawm kev tsav tsheb.

Tsis tas li ntawd xwb, kev tshawb nrhiav khoom kuj yog ib qho tseem ceeb ntawm kev siv lidar. Ua ntej txoj kev loj hlob sai ntawm kev kawm sib sib zog nqus, kev sib koom ua ke feem ntau yog siv rau kev tshawb pom cov khoom, tab sis nws nyuaj rau cais cov khoom dynamic thiab zoo li qub. Nrog rau kev txhim kho ntawm kev kawm sib sib zog nqus, taw tes huab khoom lees paub kuj siv kev kawm tob dua.

B. Muab tso rau hauv thiab navigation: siv lidar rau high-precision positioning thiab txoj kev npaj
Laser modules yog qhov tseem ceeb heev rau kev tso npe thiab kev siv navigation hauv kev tsav tsheb tsis muaj neeg siv. Nws muaj peev xwm ntawm high-precision positioning thiab txoj kev npaj los ntawm lidar. Tshwj xeeb, SLAM (Simultaneous Localization and Mapping) thev naus laus zis yog tam sim no qhov chaw ruaj khov tshaj plaws thiab tseem ceeb tshaj plaws thiab txoj hauv kev navigation. Tsis tas li ntawd, lidar qhov tseeb kev tshawb nrhiav thiab kev ua haujlwm zoo los tiv thaiv kev cuam tshuam ua rau nws "qhov muag" rau cov neeg hlau kom pom tseeb ntawm ib puag ncig, thiab los ntawm nws "cerebellum" - qhov chaw thiab kev siv tshuab navigation, nws tuaj yeem ua tiav autonomous navigation, autonomous txoj kev npaj thiab kev tiv thaiv kev tiv thaiv. , thiab lwm yam.

C. Kev tswj lub tsheb: Kev tswj xyuas meej ntawm cov tsheb tsis muaj zog yog ua tiav los ntawm cov ntaub ntawv tau los ntawm lidar
Laser modules yog ib qho tseem ceeb heev nyob rau hauv daim ntawv thov tswj tsheb nyob rau hauv lub tshav pob ntawm autonomous tsav tsheb. Nws tuaj yeem ua tiav kev tswj hwm ntawm cov tsheb autonomous los ntawm cov ntaub ntawv tau txais. Piv txwv li, los ntawm kev txheeb xyuas cov ntsiab lus huab nrog LiDAR, cov tsheb tsis muaj tsheb tuaj yeem pom qhov chaw nyob ib puag ncig, suav nrog qhov chaw, qhov loj, qhov loj thiab cov kev taw qhia ntawm kev txav ntawm cov teeb meem, thiab lwm yam, txhawm rau txiav txim siab tsav tsheb sib xws.

Tsis tas li ntawd, lidar thiab lwm yam sensors txhawb ib leeg thiab tuaj yeem txhim kho qhov tseeb ntawm lub tsheb qhov kev nkag siab ntawm ib puag ncig ib puag ncig. Qhov no yog qhov tseem ceeb heev hauv kev tsav tsheb tsis muaj zog, vim tias qhov tseeb ib puag ncig kev nkag siab yog lub hauv paus rau kev nyab xeeb thiab kev tsav tsheb zoo.

D. Kev ceeb toom kev nyab xeeb: Thaum muaj kev cuam tshuam los ze, lub laser module tuaj yeem tshaj tawm lus ceeb toom los txhim kho kev nyab xeeb ntawm kev tsav tsheb.
Daim ntawv thov ceeb toom kev nyab xeeb ntawm laser modules hauv kev tsav tsheb tsis muaj tsheb yog qhov tseem ceeb heev. Thaum muaj kev cuam tshuam los ze, lub laser module tuaj yeem tshaj tawm lus ceeb toom los txhim kho kev nyab xeeb ntawm kev tsav tsheb. Qhov no yog vim lidar tuaj yeem ntsuas qhov kev ncua deb ntawm obstacles thiab tsheb los ntawm emitting laser beams thiab tau txais cov cim qhia, yog li tshaj tawm cov lus ceeb toom raws sijhawm.

Tsis tas li ntawd, cov khoom siv sensor yog lub hauv paus rau kev tsav tsheb tsis muaj zog thiab kev pabcuam tsav tsheb, ntawm cov lidar yog qhov tseem ceeb tshaj plaws sensor rau L4 thiab siab dua autonomous tsav tsheb. Cov tsheb tsis muaj neeg siv kuj yuav tsum tau nruab nrog cov sensors xws li radar, koob yees duab, thiab satellite positioning systems raws li redundancy los txhim kho kev nyab xeeb.

Qhov zoo ntawm laser modules nyob rau hauv lub tshav pob ntawm autonomous tsav tsheb yog feem ntau reflected nyob rau hauv cov nram qab no yam:
Ua ntej ntawm tag nrho cov, nws muaj cov yam ntxwv ntawm high precision thiab muaj zog real-time kev ua tau zoo, thiab muaj peev xwm sai sai paub peb-dimensional txoj hauj lwm positioning lub hom phiaj thiab raug ntsuas ceev. Qhov thib ob, lidar muaj zog tiv thaiv kev cuam tshuam thiab tuaj yeem ua haujlwm ruaj khov hauv ntau qhov chaw ua haujlwm. Tsis tas li ntawd, lidar muaj ntau yam kev hloov pauv thiab tuaj yeem siv rau ob qho tib si luv luv, qis-ceev tsav tsheb thiab nyob deb, kev tsav tsheb ceev.

Txawm li cas los xij, daim ntawv thov ntawm laser modules nyob rau hauv lub tshav pob ntawm autonomous tsav tsheb kuj ntsib ib co kev cov nyom:
Ua ntej, tus nqi ntawm lidar yog tus nqi siab, uas txwv nws txoj kev nce qib hauv kev lag luam loj hauv daim ntawv thov. Thib ob, lidar thev naus laus zis yog qhov nyuaj thiab xav tau ntau yam kev txhawb nqa thiab kev saib xyuas. Tsis tas li ntawd, ib puag ncig yam xws li nag thiab daus tuaj yeem cuam tshuam rau kev ua haujlwm ntawm lidar. Yog li ntawd, kev tshawb fawb thiab kev tshawb fawb yav tom ntej yuav tsum tau tsom mus rau cov teeb meem no los txhawb txoj kev loj hlob thiab kev hloov pauv ntawm kev lag luam automotive lidar technology.

Txoj kev loj hlob zeem muag hauv kev tsav tsheb tsis muaj zog yog qhov dav heev, thiab laser modules, uas yog ib qho tseem ceeb rau kev tsav tsheb, kuj tseem txhim kho sai heev. Raws li kev tshawb fawb, feem ntau cov tuam txhab tam sim no tsom rau cov tsheb tsis muaj neeg tsav tsheb, cov neeg hlau thiab lidar hauv thaj chaw ntawm cov tsheb tsis muaj neeg tsav tsheb ua lawv cov lus qhia tseem ceeb.

Cov kev cai thiab kev loj hlob ntawm lub tsheb-mounted lidar nyob rau hauv daim ntawv thov scenarios xws li pab tsav tsheb thiab autonomous tsav tsheb tau raug txheeb xyuas kom meej. Piv txwv li, Hesai Technology tau tso nws thawj cov khoom lidar Pandar40 hauv xyoo 2017, thiab tau siv cov kev tshawb fawb thiab kev loj hlob hauv tib lub xyoo; nws tau tsim ib qho khoom ib nrab + tus kheej tsim SoC lidar khoom PandarGT hauv 2019; thiab tseem tau tshaj tawm lub siab-precision luv-ntau laser hauv 2020 Radar layout nyob rau hauv unmanned logistics thiab soj ntsuam thiab daim ntawv qhia chaw.

Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias txawm hais tias lidar muaj kev cia siab rau daim ntawv thov dav dav, nws qhov kev nce qib hauv cov ntawv thov kev lag luam loj tseem ntsib qee qhov teeb meem, xws li tus nqi siab thiab kev nyuaj. Yog li ntawd, kev tshawb fawb thiab kev tshawb fawb yav tom ntej yuav tsum tau tsom mus rau cov teeb meem no los txhawb txoj kev loj hlob thiab kev hloov pauv ntawm kev lag luam automotive lidar technology.
