Project Background

Kuti ikurumidze kukurudzira kubatanidzwa kweimba yeimba yeimba yeimba, ivhu rekuvaka pamwe chete uye mamwe mabasa ekumaruwa real estate kodzero yekunyoresa. Muna 2016, Yuncheng Yanhu District yakapedza ongororo yecadastral yekodzero yekushandisa imba uye ivhu rekuvaka rakaungana, richiisa hwaro hwakasimba hwekunyoreswa kwezvivakwa. Ikozvino taparura zviri pamutemo uye zvizere Property Confirmation and Registration of Rural Real Estate muYanhu District uye 3D Real Estate Modelling and Procure Project. Zviri mukati mebasa zvinosanganisira iyo yekumaruwa real estate muridzi ongororo, 1:500 chiyero topographic mepu purojekiti mepu, oblique photogrammetry, 3D modhi, uye software yekuvandudza kweiyo real estate kunyoreswa uye certification system.

Profile yekambani

Star Space (tianjin) Technology Development Co., LTD., ndeye geographic information industry service provider inobatanidza 3D data kutora uye 3D geographic information platform yekutsvaga nekusimudzira.

Bhizinesi guru rekambani ndere airborne lidar aerial ongororo, vehicular mobile laser scanning survey, pasi laser scanning survey, unmanned aerial car digital aerial survey, 4D product production and database building, 3D digital city building, 3D digital solution uye 3D animation production, GIS software yekuvandudza, nezvimwewo. Masevhisi ayo anovhara ongororo nemepu, kuronga maguta, manejimendi evhu, kuvakwa kweguta rakangwara, mhinduro dzechimbichimbi mumaguta, nharembozha, pamwe nekuongorora uye mepu yemigwagwa mikuru, pombi dzemafuta uye maindasitiri ekuchengetedza mvura.

Survey Area

Dunhu reYuncheng Salt Lake riri kumaodzanyemba kwakadziva kumadokero kwePurovhinzi yeShanxi, iri panosangana matunhu eQin, Jin neYu ari pakati nepakati peRwizi rweYellow, achibatanidza Xia County kumabvazuva, Yongji neLinyi kumadokero, Zhongtiao Mountain uye. Pinglu naRuicheng kumaodzanyemba, uye Jiwang Mountain neWanrong, Jishan naWenxi kuchamhembe. Nzvimbo iyi ine 41 km yakafara kubva kumabvazuva kusvika kumavirira, 62 makiromita kureba kubva kuchamhembe kusvika kumaodzanyemba, ine nzvimbo yakazara ye1237 square kilometers.

Chirongwa ichi chinosanganisira maguta gumi nemapfumbamwe, misha yekutonga 287, nzvimbo dzinosvika zviuru zana nemakumi matatu, inoyera nzvimbo ye100 square metres. Munguva yeprojekiti, zvakanyatsoenderana nezvinodiwa zvemagwaro akakodzera uye zviyero, chirongwa ichi chakaita yakazara yekumaruwa real estate ongororo, 1: 500 scale topographic mepu yeprojekti mepu, oblique photogrammetry, matatu-dimensional modelling, uye software kuvandudza real estate. kunyoresa uye certification system. Mari yekondirakiti yeprojekiti yaidarika 40 miriyoni yuan.

Equipment Selection

Maseti maviri emidziyo yekubhururuka nendege anoshandiswa muchirongwa ichi. Iyo DJI M300 UAV ine Chengdu Rainpoo D2 PSDK kamera, uye iyo M600 ine DG3 PROS kamera. Kugadziriswa kwemukati uchishandisa 30 komputa cluster processing, komputa ine 2080TI kana 3080 graphics kadhi, 96G memory, matatu AT(aerotriangulation) maseva ane 10T solid-state hard disk, node muchina 256 solid-state hard disk.Rainpoo inyanzvi yedrone yekumepu kamera kamera mugadziri, uye Rainpoo oblique kamera inoshandiswa zvakanyanya mubasa rekuongorora mhepo. Mifananidzo yepamusoro-yepamusoro yakaunganidzwa nekamera ndiyo vimbiso yemigumisiro ye 3d modeling.

Mhedziso yeAviation uye Ndege

Muchirongwa ichi, dhizaini yakakwira yaive 83 m, iyo yepasi resolution (GSD) yaive 1.3cm, uye oparesheni yakaitwa maererano nemusoro / divi kupindirana kwe80/70% yezvakajairwa cadastral zviyero. Nzira yacho yakaiswa kuchamhembe-kumaodzanyemba kwese kwaibvira, uye anopfuura mamirioni mana epakutanga mafoto akawanikwa. Nzvimbo yeGCP ingangoita 150 metres, uye nharaunda nekona yenzvimbo yekuyera yakawedzera huwandu nemazvo.

Data Processing

Nzvimbo yemisha iri munzvimbo yekuongorora ndeye 0.3 square kilometers, imwe yacho inosvika kupfuura 1 square metres, uye huwandu hwemifananidzo hunosvika zviuru makumi maviri. Kune mashoma mashoma ehunyanzvi matambudziko mukugadzirisa oblique modhi, inova inonyanya kushanda kwepombi. Cadastral mepu uye modhi kugadziridzwa ndiwo anonyanya hunyanzvi hwegungwa revanhu. Mabasa akadai semuenzaniso monomers, kuchengetedza data, kuratidza ruzivo uye mamwe mabasa anobatwa nesoftware yakazvimiririra yakagadziridzwa nekambani yedu.

Nekuda kwehuwandu hwemifananidzo, M3D AT(Aerial Triangulation) yakashandiswa kugadzirisa data. Ese mapurojekiti ane mabviro akafanana uye saizi yebhuroka yakafanana, kuitira kuti iyo block kodhi yemhedzisiro yeprojekiti yega yega yakasarudzika, iyo yakanakira yemhando yekuchengetedza uye kutsvaga. Iyo block musanganiswa tafura inoratidzwa pazasi:

Project Mhedziso

Parizvino, chirongwa ichi hachina kupedzwa zvachose, uye chete cheki yakapusa uye manhamba inoitwa pamhedzisiro yepakati yemuenzaniso. Mazhinji ematambudziko anogona kugadziriswa nekubvisa zvakare indasitiri yemukati uye kudhirowa mufananidzo zvakare, nepo vashoma vachida kubhururuka zvakare.

Kazhinji, kurongeka kwemuenzaniso kwakanaka, uye chiyero chekupasa chakakwirira kudarika 95%. Panyaya yemuenzaniso, DG3 modhi iri nani zvishoma pane D2 modhi pasi pemamiriro akafanana. Matambudziko emamodheru anonyanya kusanganisira aya mapoinzi anotevera: kudzoreredzwa kwenzvimbo kunokonzerwa nedhigirii yakatarisana kana kugadziriswa hakuzadzise zvinodiwa, kunaya kwemamiriro ekunze kana mhute inokonzerwa nekusajeka kwechiedza kana kuoneka.

Mufananidzo weThe Model

Usati wabhururuka, michina yeRTK inoshandiswa kuyera iyo chaiyo inorongedzerwa yenzvimbo dzepasi (senge zebra kuyambuka, mitsetse yekumaka, L-mhando yezvinangwa uye zvimwe zvakakosha mapoinzi) munzvimbo yekuyera secheki yekutarisa iyo modhi yechokwadi mune inotevera nhanho. . Iyo CS2000 coordination system inoshandiswa pacheki uye iyo yakakodzera parameter kureba inoshandiswa kukwirisa. Anotevera ndiwo mamiriro ekuyerwa kwedu kwemaficha mapoinzi. Nekuda kwenzvimbo diki, isu tinongosarudza mashoma ekuratidza.

Nhanganyaya Yekushandiswa kweZvawanikwa

Inonyanya kushandiswa kudhirowa mepu yecadastral yezvivakwa, kubatsira ongororo yemunda, kuvaka dhatabhesi, nezvimwewo (Iyo purojekiti ichiri mudanho rekutanga, uye kune mashoma akaiswa data).

Oblique modhi ndiyo yekumberi-yekupedzisira maitiro ekuyera estate, iyo inobata zvakananga chirongwa cheprojekiti. Iyo Rainpoo kamera yatakasarudza inopa purojekiti yedu rutsigiro rwakasimba. Takashandisa midziyo miviri kukanganisa chirongwa chinodarika mamirioni makumi mana emayuan. Chokutanga pane zvose, kushanda kwekushanda kwakakwirira uye kugadzikana kwakasimba. Iyo M300 inoshongedzerwa neiyo D2 kamera, iyo inogona kuona kushanda kumwe chete, uye maitiro ekushanda haana matambudziko. Zvadaro, iyo data iri nyore, inenge 30% mapikicha asina kukodzera anogona kubviswa, kuvandudza kushanda kwebasa rehofisi, iyo AT (aerial triangulation) pass rate yakakwirira, chaizvoizvo zvose zvinogona kupfuura kamwe chete, pakupedzisira, mhando yemuenzaniso yakakwirira. , zvose zviri zviviri kurongeka kwemuenzaniso uye kunaka kwemuenzaniso kune kushanda kwakanaka.
