Daim ntawv thov kev yees duab oblique tsis txwv rau cov piv txwv saum toj no, yog tias koj muaj lus nug ntxiv thov hu rau peb
Dab tsi yog oblique koob yees duab siv rau hauv kev soj ntsuam & GIS
Kev Tshawb Fawb Cadastral
Cov duab coj los ntawm oblique koob yees duab tsim kom muaj kev daws teeb meem siab thiab nthuav dav 3D qauv. Lawv pab kom muaj tseeb cadastral maps yuav tsum tau ua sai thiab yooj yim, txawm nyob rau hauv complex lossis nyuaj rau kev nkag mus rau ib puag ncig. Cov kws tshawb fawb tuaj yeem tshem tawm cov yam ntxwv ntawm cov duab, xws li cov paib, curbs, cov cim kev, cov dej tua hluav taws thiab cov dej ntws.
Kev Tshawb Fawb Av
Kev soj ntsuam dav hlau thev naus laus zis ntawm UAV / drone tuaj yeem siv rau hauv qhov pom thiab ua tau zoo heev (ntau tshaj 30 npaug ntau dua li kev siv phau ntawv) ua kom tiav daim ntawv ntsuam xyuas kev siv av. Nyob rau tib lub sijhawm, qhov tseeb ntawm txoj kev no kuj yog qhov zoo, qhov yuam kev tuaj yeem tswj tau hauv 5cm, thiab nrog kev txhim kho ntawm cov phiaj xwm dav hlau thiab cov khoom siv, qhov tseeb tuaj yeem txhim kho tsis tu ncua.
Daim duab kos duab
Nrog kev pab los ntawm uav thiab lwm lub dav hlau thauj khoom, oblique yees duab thev naus laus zis tuaj yeem khaws cov ntaub ntawv duab sai sai thiab paub txog kev ua qauv 3D tag nrho. Phau ntawv ua qauv ntawm cov nroog me thiab nruab nrab uas siv sijhawm 1-2 xyoos tuaj yeem ua tiav hauv 3-5 lub hlis nrog kev pab ntawm oblique photography technology.
Tso zis DEM/DOM/DSM/DLG
Oblique photography cov ntaub ntawv yog ntsuas cov duab cov ntaub ntawv nrog spatial txoj hauj lwm cov ntaub ntawv, uas muaj peev xwm tso zis DSM, DOM, TDOM, DLG thiab lwm yam ntaub ntawv tshwm sim nyob rau tib lub sij hawm, thiab yuav hloov cov tsoos aerial photography.
3D GIS hais txog:
Cov ntaub ntawv muaj nplua nuj kev faib tawm
Txhua txheej yog kev tswj hwm qhov khoom
Txhua yam khoom muaj vectors thiab cwj pwm ntawm tus qauv 3D
Tsis siv neeg rho tawm cov khoom literal attributes
Dab tsi yog cov txiaj ntsig ntawm oblique koob yees duab hauv kev soj ntsuam & GIS
Kev soj ntsuam thiab ua daim ntawv qhia thiab GIS cov kws tshaj lij tau tig mus rau kev tsis muaj neeg ua haujlwm thiab 3D kev daws teeb meem kom ua haujlwm tau zoo dua. Rainpoo oblique koob yees duab pab koj:
(1) Txuag sijhawm. Ib lub davhlau, tsib daim duab los ntawm cov ces kaum sib txawv, siv sijhawm tsawg dua hauv kev sau cov ntaub ntawv.
(2) Tshem tawm GCPs (thaum khaws qhov tseeb). Ua tiav qhov kev soj ntsuam-qib qhov tseeb nrog lub sijhawm tsawg, cov neeg tsawg, thiab cov cuab yeej siv tsawg. koj yuav tsis xav tau cov ntsiab lus tswj hauv av.
(3) Slash koj lub sijhawm ua haujlwm tom qab.Our ntse txhawb software zoo heev txo tus naj npawb ntawm cov duab (Sky-Filter), thiab txhim kho kev ua tau zoo ntawm AT, txo tus nqi ntawm kev ua qauv, thiab ntxiv dag zog rau kev ua haujlwm ntawm tag nrho cov dej ntws. (Sky-Target).
(4) Nyob nyab xeeb.Siv drones thiab oblique koob yees duab los sau cov ntaub ntawv los ntawm saum toj no cov ntaub ntawv / lub tsev, tsis tsuas yog yuav ua kom muaj kev ruaj ntseg ntawm cov neeg ua hauj lwm, tab sis kuj muaj kev ruaj ntseg ntawm drones.
