Mbiri ya Ntchito

Pofuna kufulumizitsa kupititsa patsogolo kuphatikizika kwa malo ogulitsa nyumba, malo omanga pamodzi ndi ntchito zina zolembera ufulu wa kumidzi. Mu 2016, Chigawo cha Yuncheng Yanhu chinamaliza kufufuza kwa cadastral za ufulu wogwiritsa ntchito nyumba ndi malo omangamanga, ndikuyika maziko olimba a kulembetsa nyumba. Tsopano takhazikitsa mwalamulo komanso momveka bwino za Katundu Wotsimikizira ndi Kulembetsa Malo Ogulitsa Malo akumidzi m'boma la Yanhu ndi Project 3D Real Estate Modelling and Procure Project. Zomwe zili muntchitoyi zikuphatikiza kafukufuku wa eni eni nyumba akumidzi, 1:500 scale topographic map project, oblique photogrammetry, 3D modelling, and software development of the real estate registration and certification system.

Mbiri Yakampani

Star Space (tianjin) Technology Development Co., LTD., ndi kampani yopereka zidziwitso za malo omwe akuphatikiza kupeza kwa data ya 3D ndi kafukufuku ndi chitukuko cha 3D geographic information platform.

Bizinesi yayikulu ya kampaniyi ndi kafukufuku wam'mlengalenga wa lidar, kafukufuku wamagalimoto amtundu wa laser, kafukufuku wowunikira laser pansi, kafukufuku wopangidwa ndi mlengalenga wosayendetsedwa ndi ndege, kupanga zinthu za 4D ndi zomangamanga, zomangamanga za mzinda wa 3D, njira ya digito ya 3D ndi kupanga makanema ojambula a 3D, Kupititsa patsogolo mapulogalamu a GIS, ndi zina zotero. Ntchito zake zimaphatikizapo kufufuza ndi kupanga mapu, kukonza mizinda, kasamalidwe ka nthaka, kumanga mizinda mwanzeru, kuyankha mwadzidzidzi m'tawuni, kuyang'anira mafoni, komanso kufufuza ndi kupanga mapu a misewu yayikulu, mapaipi amafuta ndi mafakitale osungira madzi.

Malo Ofufuza

Chigawo cha Yuncheng Salt Lake chili kum'mwera chakumadzulo kwa chigawo cha Shanxi, chomwe chili pamalire a zigawo za Qin, Jin ndi Yu pakatikati pa mtsinje wa Yellow River, kulumikiza Xia County kum'mawa, Yongji ndi Linyi kumadzulo, phiri la Zhongtiao ndi Pinglu ndi Ruicheng kumwera, ndi Jiwang Mountain ndi Wanrong, Jishan ndi Wenxi kumpoto. Derali ndi makilomita 41 m’lifupi kuchokera kum’maŵa mpaka kumadzulo, makilomita 62 kuchokera kumpoto mpaka kum’mwera, ndi malo okwana 1237 masikweya kilomita.

Ntchitoyi ikuphatikizapo matauni a 19, midzi yoyang'anira 287, malo okwana 130,000, omwe amayesa malo a 100 sq. Panthawi ya polojekitiyo, mogwirizana ndi zofunikira za zikalata zoyenera ndi miyezo, polojekitiyi inachitika kafukufuku waumwini waumwini, 1: 500 scale topographic map project, oblique photogrammetry, atatu-dimensional modeling, ndi chitukuko cha mapulogalamu a malo ogulitsa nyumba. kalembera ndi certification system. Kuchuluka kwa mgwirizano wa ntchitoyi kunali kopitilira 40 miliyoni yuan.

Kusankha Zida

Mitundu iwiri ya zida zoyendetsa ndege zapamtunda zimagwiritsidwa ntchito pantchitoyi. DJI M300 UAV ili ndi kamera ya Chengdu Rainpoo D2 PSDK, ndipo M600 ili ndi kamera ya DG3 PROS. Kukonzekera kwamkati pogwiritsa ntchito 30 compuster cluster processing, kompyuta yokhala ndi 2080TI kapena 3080 graphics khadi, 96G memory, ma seva atatu a AT(aerotriangulation) okhala ndi 10T solid-state hard disk, node machine 256 solid-state hard disk.Rainpoo ndi katswiri wojambula mapu a drone kamera. wopanga, ndi kamera ya Rainpoo oblique imagwiritsidwa ntchito kwambiri mu polojekiti yowunikira ndege. Zithunzi zapamwamba kwambiri zomwe zimasonkhanitsidwa ndi kamera ndizotsimikiziranso za 3d modeling.

Chidule cha Ndege ndi Ndege

Ntchitoyi, kutalika kwa mapangidwe ake kunali 83 m, kusamvana kwapansi (GSD) kunali 1.3cm, ndipo ntchitoyi inkachitika molingana ndi mutu / mbali ya 80 / 70% ya miyeso yachilendo ya cadastral. Njirayi idayikidwa kulowera kumpoto-kum'mwera momwe ndingathere, ndipo zithunzi zoyambirira zopitilira 4 miliyoni zidapezedwa. Kutalikirana kwa GCP ndi pafupifupi 150 metres, ndipo mphepete ndi ngodya ya malo oyezera zidachulukitsa kuchuluka bwino.

Kukonza Data

Dera la midzi yomwe ili m'dera la kafukufukuyo ndi pafupifupi ma kilomita 0.3, ena omwe amafika kupitirira 1 lalikulu mamita, ndipo chiwerengero cha zithunzi ndi pafupifupi 20,000. Pali zovuta zochepa zaukadaulo pakukonza mtundu wa oblique, womwe kwenikweni ndi ntchito yamapaipi. Mapu a Cadastral ndi kusinthidwa kwachitsanzo makamaka njira za nyanja ya anthu. Ntchito monga ma monomers achitsanzo, kusungirako deta, kuwonetsa zidziwitso ndi ntchito zina zimayendetsedwa ndi pulogalamu yodziyimira payokha ndi kampani yathu.

Chifukwa cha kuchuluka kwa zithunzi, M3D AT(Aerial Triangulation) idagwiritsidwa ntchito pokonza deta. Ma projekiti onse ali ndi chiyambi chofanana ndi kukula kwa chipika, kotero kuti code block ya zotsatira za polojekiti iliyonse ndi yapadera, yomwe ili yabwino kusungirako chitsanzo ndi kufufuza. Tebulo lophatikizana la block likuwonetsedwa pansipa:

Mapeto a Ntchito

Pakalipano, ntchitoyi siinamalizidwe kotheratu, ndipo cheke chophweka ndi ziwerengero zimapangidwa pa zotsatira zapakatikati za chitsanzo. Mavuto ambiri amatha kuthetsedwa mwa kubwezeretsanso makampani amkati ndi kujambula chithunzicho, pamene ochepa amafunika kuwulukanso.

Nthawi zambiri, kulondola kwachitsanzo ndikwabwino, ndipo chiwongolero chake ndi chachikulu kuposa 95%. Pankhani yachitsanzo, mtundu wa DG3 ndi wabwinoko pang'ono kuposa mtundu wa D2 pansi pamikhalidwe yomweyi. Mavuto amitundu amaphatikizanso mfundo zotsatirazi: kuwongolera kwamtunda komwe kumachitika chifukwa cha kuchulukana kwa digiri kapena kusamvana sikukwaniritsa zofunikira, nyengo yamvula kapena chifunga chobwera chifukwa cha kusawunikira kokwanira kapena mawonekedwe.

Chithunzi cha The Model

Musananyamuke, zida za RTK zimagwiritsidwa ntchito kuyeza zofananira bwino za malo omwe ali pansi (monga mbidzi zowoloka, mizere yolembera, milingo yamtundu wa L ndi mfundo zina zofunika kwambiri) m'dera loyezera ngati malo oyendera kuti muwonetsetse kulondola kwachitsanzo pambuyo pake. . CS2000 coordinate system imagwiritsidwa ntchito poyang'ana ndipo kutalika koyenera kumagwiritsidwa ntchito pokweza. Zotsatirazi ndi momwe timayezera magawo athu. Chifukwa cha malo ochepa, timangosankha ochepa chabe kuti tisonyeze.

Mawu Oyamba pa Kugwiritsa Ntchito Zotsatira

Amagwiritsidwa ntchito kwambiri pojambula mapu a cadastral of real estate, kuthandizira kufufuza kumunda, kumanga database, ndi zina zotero (Pulojekitiyi idakali yoyambirira, ndipo pali zochepa zomwe zimagwiritsidwa ntchito).

Chitsanzo cha Oblique ndi njira yakutsogolo yoyezera nyumba, yomwe imakhudza mwachindunji ndondomeko ya polojekiti. Kamera ya Rainpoo yomwe tidasankha imapereka chithandizo champhamvu cha polojekiti yathu. Tidagwiritsa ntchito zida ziwiri kukhudza projekiti yopitilira 40 miliyoni ya yuan. Choyamba, magwiridwe antchito ndi apamwamba ndipo kukhazikika kumakhala kolimba. M300 ili ndi kamera ya D2, yomwe imatha kuzindikira ntchito imodzi, ndipo ntchitoyo imakhala yopanda mavuto. Kenako, deta ndiyosavuta, pafupifupi 30% zithunzi zosavomerezeka zitha kuchotsedwa, kukonza magwiridwe antchito aofesi, kuchuluka kwa AT(aerial triangulation) ndikokwera, kwenikweni zonse zimatha kudutsa kamodzi, pomaliza, mtundu wamtunduwu ndi wapamwamba. , kulondola kwachitsanzo ndi khalidwe lachitsanzo zimakhala ndi ntchito yabwino.
