TSAB NTAWV
Kab lus no yog ua raws li kev kuaj sim thiab lub hom phiaj los piav qhia txog qhov sib txawv latency ntawm covkev sib txuas lus wireless thiab cable txuas ntawm lub tsheb tsis muaj neeg tsav tsheb hauv av nrog ZED VR lub koob yees duab.Thiab xyuas seb qhovwireless txuasmuaj kev ntseeg siab rau kev ua kom pom kev pom 3D ntawm UGV.
1. Taw qhia
UGV yog dav siv nyob rau hauv ntau yam struts nyuaj mus cuag los yog txaus ntshai rau tib neeg kev nyab xeeb, xws li rau qhov chaw ntawm ib tug natural kev puas tsuaj, hluav taws xob, los yog defuse lub foob pob nyob rau hauv cov tub rog.Hauv kev tshawb nrhiav hauv xov tooj thiab cawm UGV, 3D pom kev pom ntawm UGV ib puag ncig muaj kev cuam tshuam tob rau tib neeg-neeg hlau-kev paub txog ntawm UGV ib puag ncig.Qhov twg yuav tsum tau
Lub sijhawm tiag tiag synchronization ntawm lub xeev cov ntaub ntawv, cov lus tawm tswv yim ntawm lub sijhawm tiag tiag ntawm kev taw qhia, cov ntaub ntawv ua haujlwm thiab cov lus tawm tswv yim synchronous ntawm tej thaj chaw deb neeg hlau video.Nrog rau cov ntaub ntawv ntawm lub sijhawm tiag tiag UGV tuaj yeem ua tau meej thiab wirelessly tswj nyob rau hauv qhov ntev thiab tsis-kab-ntawm-pob qhov chaw.
Cov ntaub ntawv xov xwm no suav nrog ob lub pob ntawv luv luv thiab cov ntaub ntawv xov xwm streaming real-time, uas tau sib xyaw ua ke thiab xa mus rau kev tswj hwm lub platform los ntawm kev sib kis.Obviously, muaj kev xav tau siab heev ntawm kev ncua ntawm qhov txuas wireless.
1.1.Wireless kev sib txuas lus txuas
IWAVE wireless kev sib txuas lus txuas FDM-6600 Xov tooj cua Module muaj kev ruaj ntseg IP sib txuas nrog qhov kawg-rau-kawg encryption thiab seamless Layer 2 kev sib txuas, FDM-6600 module tuaj yeem yooj yim ua ke rau yuav luag txhua lub platform lossis daim ntawv thov.
Nws yog qhov hnyav thiab qhov me me yog qhov zoo tagnrho rau SWaP-C (Qhov Loj, Qhov hnyav, Lub Zog thiab Tus Nqi) - UAVs thiab cov tsheb tsis muaj neeg siv hauv UHF, S-Band thiab C-Band zaus.Nws muab kev ruaj ntseg, txhim khu kev qha kev sib txuas rau lub sijhawm sib kis video rau kev soj ntsuam ntawm lub xov tooj ntawm tes, NLOS (tsis-kab-ntawm-pom) kev sib txuas lus, thiab hais kom ua thiab tswj cov drones thiab robotics.
1.2.Unmanned av tsheb
Tus neeg hlau muaj peev xwm ua tau ntau qhov chaw thiab tuaj yeem nce obstacles.Nws txuas nrog lub koob yees duab ZED rau kev ntes cov yeeb yaj kiab pub ncig UGV.Thiab UGV siv FDM-6600 wireless txuas kom tau txais video pub los ntawm ZED on-board koob yees duab.Ib txhij video pub xa mus rau tus neeg teb xov tooj chaw nres tsheb lub computer rau tsim VR scenes los ntawm cov ntaub ntawv video tau los ntawm neeg hlau.
2. Kev xeemCxav:
Kuajhauvncua qhov sib txawv ntawmIWAVEwireless kis tau tus mob thiab RJ45 cable kis tau tus mob thaum kis ZED Lub Koob Yees Duab 720P * 30FS video los ntawm tus neeg hlau mus rau tom qab-kawg VRserver.
Ua ntej siv IWAVE wireless txuas los xa cov video streaming, tswj cov ntaub ntawv thiab lwm yam ntaub ntawv sensor los ntawm NVIDIA IPC.
Thib ob siv RJ45 cable los hloov qhov txuas wireless rau kev xa cov duab cov ntaub ntawv, tswj cov ntaub ntawv thiab cov ntaub ntawv sensor los ntawm cov neeg hlau sab mus rau sab nraud.
3. Cov txheej txheem xeem
ZED Lub Koob Yees Duab ntawm cov neeg hlau tua lub sijhawm nres lub sijhawm software, thiab tom qab ntawd muab VR server thiab cov software nres nres rau tib lub vijtsam kom thaij duab tib yam (dual focus point) thiab sau qhov sib txawv ntawm ob lub sijhawm ntawm tib daim duab.
4.Test Results thiab Analysis:

5. Cov lus xaus:
Hauv qhov xwm txheej no, tsis muaj qhov sib txawv tseem ceeb ntawm latency ntawm kev sib txuas lus wireless rau kev xav tau video siab, kis tau tus mob, txiav txim siab, thiab tso saib, thiab latency ntawm kev xa ncaj qha ntawm lub network cable.
