Qhov project Background

Txhawm rau txhawm rau txhawm rau txhawb kev sib koom ua ke ntawm vaj tse vaj tsev av, kev tsim vaj tsev sib sau ua ke thiab lwm qhov chaw nyob deb nroog txoj cai sau npe ua haujlwm. Nyob rau hauv 2016, Yuncheng Yanhu District tau ua tiav daim ntawv ntsuam xyuas cadastral ntawm txoj cai siv homestead thiab collective av, nteg lub hauv paus ruaj khov rau kev sau npe ntawm vaj tse. Tam sim no peb tau ua tiav thiab nthuav tawm Lub Chaw Pom Zoo thiab Kev Sau Npe ntawm Cov Khoom Siv Hauv Nroog Hauv Nroog Yanhu thiab 3D Kev Tsim Vaj Tsev Ua Qauv thiab Kev Ua Haujlwm. Cov ntsiab lus ua haujlwm suav nrog kev tshawb fawb txog vaj tsev nyob deb nroog, 1: 500 scale topographic map project mapping, oblique photogrammetry, 3D modeling, thiab software txhim kho kev sau npe vaj tsev thiab ntawv pov thawj.

Tuam txhab Profile

Lub Hnub Qub Chaw (tianjin) Technology Development Co., LTD., yog lub chaw muab kev pabcuam kev lag luam geographic chaw muab kev koom ua ke 3D cov ntaub ntawv tau txais thiab 3D geographic information platform kev tshawb fawb thiab kev loj hlob.

Lub lag luam tseem ceeb ntawm lub tuam txhab yog airborne lidar aerial daim ntawv ntsuam xyuas, vehicular mobile laser scanning daim ntawv ntsuam xyuas, hauv av laser scanning daim ntawv ntsuam xyuas, unmanned aerial tsheb digital aerial daim ntawv ntsuam xyuas, 4D khoom tsim thiab database tsim, 3D digital nroog tsim, 3D digital daws thiab 3D animation ntau lawm, GIS software txhim kho, thiab lwm yam. Nws cov kev pabcuam suav nrog kev tshawb fawb thiab kev qhia hauv nroog, kev npaj hauv nroog, kev tswj xyuas thaj av, kev tsim kho hauv nroog ntse, lub nroog cov lus teb thaum muaj xwm txheej ceev, kev saib xyuas ntawm lub xov tooj ntawm tes, nrog rau kev sojntsuam thiab kos duab ntawm txoj kev loj, roj kav dej thiab kev txuag dej hauv kev lag luam.

Tshawb xyuas cheeb tsam

Yuncheng Salt Lake District nyob rau sab hnub poob ntawm Shanxi xeev, nyob rau ntawm qhov sib tshuam ntawm Qin, Jin thiab Yu xeev nyob rau nruab nrab ntawm tus dej daj, txuas Xia County sab hnub tuaj, Yongji thiab Linyi nyob rau sab hnub poob, Zhongtiao Roob thiab Pinglu thiab Ruicheng nyob rau sab qab teb, thiab Jiwang Roob thiab Wanrong, Jishan thiab Wenxi nyob rau sab qaum teb. Lub cheeb tsam yog 41 km dav ntawm sab hnub tuaj mus rau sab hnub poob, 62 mais ntev ntawm sab qaum teb mus rau sab qab teb, nrog rau tag nrho cheeb tsam ntawm 1237 square kilometers.

Txoj haujlwm no suav nrog tag nrho 19 lub nroog, 287 lub zos tswj hwm, thaj tsam li 130,000 thaj av, ntsuas thaj tsam ntawm 100 square meters. Thaum lub sijhawm ua haujlwm, nruj me ntsis raws li cov cai ntawm cov ntaub ntawv cuam tshuam thiab cov qauv, qhov project tau ua tiav daim ntawv ntsuam xyuas pej xeem nyob deb nroog, 1: 500 scale topographic map project mapping, oblique photogrammetry, peb-dimensional qauv, thiab software tsim kho vaj tse. sau npe thiab ntawv pov thawj system. Daim ntawv cog lus ntawm qhov project yog ntau tshaj 40 lab yuan.

Kev xaiv khoom siv

Ob txheej ntawm cov cuab yeej siv dav hlau teb tau siv hauv qhov project no. DJI M300 UAV yog nruab nrog Chengdu Rainpoo D2 PSDK lub koob yees duab, thiab M600 yog nruab nrog DG3 PROS lub koob yees duab. Kev ua haujlwm sab hauv siv 30 lub khoos phis tawj ua haujlwm, khoos phis tawj nruab nrog 2080TI lossis 3080 daim npav duab, 96G nco, peb lub AT (aerotriangulation) servers nrog 10T solid-state hard disk, node tshuab 256 solid-state hard disk.Rainpoo yog lub koob yees duab drone kev tshaj lij chaw tsim tshuaj paus, thiab Rainpoo oblique koob yees duab yog dav siv nyob rau hauv lub aerial surveying project.The high-qib zoo dluab sau nrog lub koob yees duab yog cov nyhuv guarantee ntawm 3d qauv.

Txheej txheem cej luam ntawm Aviation thiab Flight

Hauv qhov project no, qhov tsim qhov siab yog 83 m, qhov kev daws teeb meem hauv av (GSD) yog 1.3cm, thiab kev ua haujlwm tau ua raws li cov lus qhia / sab sib tshooj ntawm 80/70% ntawm cov pa cadastral ntsuas. Txoj kev tau muab tso rau sab qaum teb-sab qab teb kom deb li deb tau, thiab tau txais ntau dua 4 lab daim duab qub. Qhov sib nrug ntawm GCP yog kwv yees li 150 meters, thiab lub periphery thiab ces kaum ntawm cheeb tsam ntsuas tau nce kom muaj nuj nqis.

Kev ua cov ntaub ntawv

Lub cheeb tsam ntawm lub zos nyob rau hauv lub cheeb tsam ntawm kev soj ntsuam yog nyob rau hauv lub hauv paus ntawm 0.3 square kilometers, ib co ntawm uas ncav cuag ntau tshaj 1 square meters, thiab cov duab muaj txog 20,000. Muaj ob peb qhov teeb meem hauv kev ua cov qauv oblique, uas yog qhov pib ua haujlwm ntawm cov kav dej. Cadastral daim ntawv qhia thiab kev hloov qauv yog feem ntau yog cov tactics ntawm tib neeg hiav txwv. Kev ua haujlwm xws li qauv monomers, cov ntaub ntawv khaws cia, cov ntaub ntawv tso saib thiab lwm yam haujlwm yog tswj hwm los ntawm software nws tus kheej tsim los ntawm peb lub tuam txhab.

Vim muaj cov duab ntau, M3D AT (Aerial Triangulation) tau siv los ua cov ntaub ntawv. Tag nrho cov haujlwm muaj tib lub hauv paus chiv keeb thiab tib qhov thaiv qhov loj, yog li cov block code ntawm cov txiaj ntsig ntawm txhua qhov project yog qhov tshwj xeeb, uas yooj yim rau cov qauv cia thiab tshawb nrhiav. Cov lus block ua ke yog qhia hauv qab no:

Qhov project xaus

Tam sim no, qhov project no tsis tau ua tiav tag nrho, thiab tsuas yog ib qho kev kuaj xyuas yooj yim thiab cov txheeb cais tau ua los ntawm cov txiaj ntsig nruab nrab ntawm cov qauv. Feem ntau ntawm cov teeb meem tuaj yeem daws tau los ntawm kev rov ua haujlwm hauv kev lag luam sab hauv thiab kos duab dua, thaum qee qhov yuav tsum tau ya dua.

Feem ntau, qhov tseeb ntawm tus qauv yog qhov zoo, thiab tus nqi dhau yog siab dua 95%. Nyob rau hauv cov nqe lus ntawm tus qauv, DG3 qauv yog me ntsis zoo dua D2 qauv nyob rau hauv tib yam kev mob. Cov teeb meem ntawm cov qauv feem ntau suav nrog cov ntsiab lus hauv qab no: qhov kev daws teeb meem los ntawm kev sib tshooj lossis kev daws teeb meem tsis ua raws li qhov yuav tsum tau ua, huab cua los nag lossis huab cua tshwm sim los ntawm qhov pom tsis txaus lossis pom kev.

Screenshot ntawm Tus Qauv

Ua ntej lub davhlau, RTK cov cuab yeej siv los ntsuas qhov kev sib koom ua ke ntawm cov ntsiab lus hauv av (xws li zebra hla, cov kab cim, L-hom hom phiaj thiab lwm yam ntsiab lus tseem ceeb) hauv cheeb tsam ntsuas raws li qhov chaw kuaj xyuas cov qauv raug nyob rau theem tom ntej. . CS2000 kev tswj xyuas qhov system yog siv rau qhov chaw kuaj xyuas thiab qhov ntsuas qhov siab yog siv rau kev nce siab. Hauv qab no yog qhov xwm txheej ntawm peb qhov ntsuas ntawm cov ntsiab lus tshwj xeeb. Vim qhov chaw txwv, peb tsuas yog xaiv ob peb ntawm lawv los qhia.

Taw qhia rau Kev Siv Cov Kev Ntsuas

Nws yog tsuas yog siv los kos cadastral daim ntawv qhia ntawm vaj tse, pab teb daim ntawv ntsuam xyuas, kev tsim database, thiab lwm yam. (Qhov project tseem nyob rau theem pib, thiab muaj ob peb cov ntaub ntawv siv).

Oblique qauv yog cov txheej txheem pem hauv ntej ntawm kev ntsuas vaj tsev, uas cuam tshuam ncaj qha rau lub sijhawm ua haujlwm. Lub koob yees duab Rainpoo peb xaiv muab peb txoj haujlwm txhawb nqa. Peb siv ob lub cuab yeej cuam tshuam rau qhov project ntawm ntau tshaj 40 lab yuan. Ua ntej ntawm tag nrho cov, lub lag luam efficiency yog siab thiab stability yog muaj zog. Lub M300 tau nruab nrog lub koob yees duab D2, uas tuaj yeem paub txog kev ua haujlwm ib leeg, thiab cov txheej txheem ua haujlwm yog qhov tsis muaj teeb meem. Tom qab ntawd, cov ntaub ntawv yooj yim, kwv yees li 30% cov duab tsis raug tshem tawm tuaj yeem raug tshem tawm, txhim kho kev ua haujlwm ntawm lub chaw ua haujlwm, AT (air triangulation) dhau tus nqi siab, txhua yam tuaj yeem dhau ib zaug, thaum kawg, qhov zoo ntawm cov qauv yog siab. , ob qho tib si tus qauv raug thiab qhov zoo ntawm cov qauv muaj kev ua haujlwm zoo.
