Cov iav qhov muag ntsesmuaj qhov pom dav heev thiab tuaj yeem ntes tau ntau yam ib puag ncig, tab sis muaj kev cuam tshuam. Cov thev naus laus zis Fisheye stitching tuaj yeem sib xyaw thiab ua cov duab thaij los ntawm ntau lub lens fisheye, tshem tawm kev cuam tshuam los ntawm kev kho kom raug, thiab thaum kawg tsim cov duab panoramic. Nws muaj ntau yam kev siv hauv ntau yam lag luam. Cov thev naus laus zis Fisheye stitching kuj muaj cov ntawv thov tseem ceeb hauv kev tsav tsheb robot.
Cov thev naus laus zis Fisheye stitching muab rau lub neeg hlau nrog lub peev xwm pom kev ib puag ncig panoramic los ntawm kev koom ua ke ntawm kev pom dav dav ntawm ntau lub lens fisheye, daws tau zoo cov teeb meem ntawm kev pom tsawg thiab ntau qhov chaw dig muag hauv kev navigation pom kev ib txwm muaj. Nws cov ntawv thov tseem ceeb hauv kev navigation neeg hlau yog raws li nram no:
1.Kev pom ib puag ncig thiab kev tsim daim ntawv qhia
Cov thev naus laus zis Fisheye stitching tuaj yeem muab 360 ° ultra-wide-angle thiab dav-saib ib puag ncig, pab cov neeg hlau sai sai tsim cov ntawv qhia panoramic siab daws teeb meem thiab pom tag nrho cov ib puag ncig, uas pab lawv nrhiav thiab npaj cov kev thiab zam cov chaw dig muag, tshwj xeeb tshaj yog nyob rau hauv qhov chaw nqaim (xws li sab hauv tsev, tsev rau khoom) lossis cov chaw ib puag ncig dynamic.
Ntxiv mus, cov txheej txheem sib txuas duab fisheye ua tiav qhov kev sib xyaw ua ke ntawm cov duab meej heev los ntawm kev rho tawm cov ntsiab lus tshwj xeeb, kev sib phim thiab kev ua kom zoo dua, muab qhov chaw ruaj khov rau tus neeg hlau.
Los ntawm cov duab panoramic stitched, tus neeg hlau tuaj yeem ua SLAM (simultaneous localization thiab mapping) zoo dua, siv qhov zoo ntawm qhov pom loj ntawmlub lens qhov muag ntseskom ua tiav qhov kev tsim daim ntawv qhia kev taw qhia ob-seem uas muaj qhov tseeb siab thiab nrhiav nws qhov chaw.

2.Kev nrhiav thiab kev zam kev cuam tshuam
Daim duab panoramic uas siv fisheye xaws tuaj yeem npog thaj tsam 360° nyob ib puag ncig lub neeg hlau, thiab tuaj yeem ntes tau cov teeb meem nyob ib puag ncig lub neeg hlau hauv lub sijhawm tiag tiag, xws li cov teeb meem nyob rau sab saum toj lossis hauv qab lub chassis, suav nrog cov khoom nyob ze thiab deb. Ua ke nrog cov algorithms kawm tob, lub neeg hlau tuaj yeem txheeb xyuas cov teeb meem static lossis dynamic (xws li cov neeg taug kev thiab tsheb) thiab npaj txoj kev zam kev cuam tshuam.
Ntxiv mus, rau qhov kev cuam tshuam ntawm cov ntug ntawm daim duab fisheye, yuav tsum muaj cov txheej txheem kho kom raug (xws li kev kos duab inverse perspective mapping) los kho qhov kev sib raug zoo tiag tiag kom tsis txhob txiav txim siab tsis raug qhov chaw ntawm cov teeb meem. Piv txwv li, hauv kev tsav tsheb sab hauv tsev, daim duab panoramic uas lub koob yees duab fisheye ntes tau tuaj yeem pab tus neeg hlau kho nws txoj kev mus rau lub sijhawm tiag tiag thiab zam kev cuam tshuam.
3.Kev ua tau zoo tiag tiag thiab kev hloov kho rau cov chaw ib puag ncig dynamic
Qhov muag ntsesCov thev naus laus zis xaws kuj tseem ceeb rau kev ua haujlwm tiag tiag hauv kev tsav tsheb robot. Hauv ib puag ncig mobile lossis dynamic, fisheye stitching txhawb nqa kev hloov kho tshiab ntawm daim ntawv qhia (xws li DS-SLAM) thiab tuaj yeem teb rau kev hloov pauv ib puag ncig sai sai hauv lub sijhawm tiag tiag.
Tsis tas li ntawd xwb, cov duab panoramic tuaj yeem muab ntau yam ntxwv ntawm cov qauv, txhim kho qhov tseeb ntawm kev kuaj pom lub voj voog, thiab txo cov kev ua yuam kev ntawm qhov chaw.

4.Kev pom qhov chaw thiab kev npaj txoj kev
Los ntawm cov duab panoramic uas xaws los ntawm cov duab fisheye, lub neeg hlau tuaj yeem rho tawm cov ntsiab lus tshwj xeeb rau kev pom qhov chaw thiab txhim kho qhov tseeb ntawm qhov chaw. Piv txwv li, nyob rau hauv ib puag ncig sab hauv tsev, lub neeg hlau tuaj yeem paub sai sai txog qhov kev teeb tsa ntawm chav, qhov chaw ntawm lub qhov rooj, kev faib tawm ntawm cov teeb meem, thiab lwm yam los ntawm cov duab panoramic.
Tib lub sijhawm, raws li qhov pom panoramic, tus neeg hlau tuaj yeem npaj txoj kev taug kev kom raug dua, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig nyuaj xws li txoj kev nqaim thiab thaj chaw muaj neeg coob coob. Piv txwv li, nyob rau hauv ib puag ncig tsev rau khoom uas muaj ntau yam teeb meem, tus neeg hlau tuaj yeem nrhiav txoj kev ceev tshaj plaws mus rau qhov chaw lub hom phiaj los ntawm cov duab panoramic thaum zam kev sib tsoo nrog cov teeb meem xws li txee thiab khoom.
5.Kev sib koom tes ntawm ntau tus neeg hlau
Ntau tus neeg hlau tuaj yeem sib qhia cov ntaub ntawv ib puag ncig los ntawmqhov muag ntsesthev naus laus zis xaws, tsim cov ntawv qhia ib puag ncig panoramic faib tawm, thiab sib koom tes kev taw qhia, kev zam kev cuam tshuam, thiab kev faib haujlwm, xws li cov neeg hlau sib koom ua ke hauv kev khaws khoom thiab kev xa khoom.
Ua ke nrog lub moj khaum xam zauv faib tawm thiab siv cov ntsiab lus panoramic feature matching, txhua tus neeg hlau tuaj yeem ua cov duab fisheye hauv zos thiab muab lawv sib xyaw ua ke rau hauv daim ntawv qhia thoob ntiaj teb, ua kom paub txog qhov chaw sib piv ntawm cov neeg hlau thiab txo qhov yuam kev ntawm qhov chaw.
Ntau tus neeg hlau ua tiav kev sib koom tes los ntawm kev siv tshuab fisheye stitching
Cov thev naus laus zis fisheye stitching kuj tseem siv rau hauv cov xwm txheej tshwj xeeb, xws li kev saib xyuas kev tsav tsheb qeeb qeeb thiab cov txheej txheem pab tsav tsheb kom muaj kev nyab xeeb. Los ntawm kev sib txuas duab fisheye, lub kaw lus tuaj yeem tsim kom pom kev zoo nkauj los pab cov neeg tsav tsheb lossis cov neeg hlau pom kev zoo dua ib puag ncig.
Tsis tas li ntawd xwb, cov thev naus laus zis fisheye stitching kuj tseem siv tau ua ke nrog lwm cov sensors (xws li lidar, depth sensors, thiab lwm yam) los txhim kho kev ua haujlwm ntawm lub navigation system.
Hauv luv luv,qhov muag ntsesCov thev naus laus zis xaws tau siv dav hauv kev tsav tsheb neeg hlau, tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej uas xav tau kev pom ib puag ncig loj thiab qhov chaw tiag tiag. Nrog rau kev hloov kho tas li thiab kev txhim kho ntawm cov thev naus laus zis thiab cov algorithms, cov xwm txheej ntawm kev siv tshuab xaws fisheye yuav raug nthuav dav ntxiv, thiab nws cov kev cia siab ntawm daim ntawv thov yog dav.
