Imvelaphi yeProjekthi

Ukuze kukhawuleziswe ukukhuthaza ukuhlanganiswa komhlaba wezindlu zokuhlala, umhlaba wokwakha ngokubambisana kunye nomnye umsebenzi wokubhaliswa kwamalungelo omhlaba wasemaphandleni. Kwi-2016, iSithili saseYuncheng Yanhu sagqiba uphando lwe-cadastral lwelungelo lokusebenzisa indawo yokuhlala kunye nomhlaba wokwakha ngokubambisana, ukubeka isiseko esiqinileyo sokubhaliswa kwendawo yokuhlala. Ngoku siye saphehlelela ngokusemthethweni nangokubanzi uQinisekiso lwePropati kunye noBhaliso lweNdawo yaseMaphandleni kwiSithili saseYanhu kunye neProjekthi ye-3D Real Estate Modeling and Procure. Imixholo yomsebenzi ibandakanya uphando lobunini bezindlu zasemaphandleni, isikali se-1:500 semephu yemephu yemephu yemephu yemephu yemephu, i-oblique photogrammetry, imodeli ye-3D, kunye nophuhliso lwesoftware yobhaliso kunye nenkqubo yoqinisekiso.

Iprofayile yekhampani

I-Star Space (i-tianjin) i-Technology Development Co., LTD., ngumboneleli wenkonzo yolwazi lwejografi odibanisa ukufunyanwa kwedatha ye-3D kunye nophando lweqonga lolwazi lwejografi kunye nophuhliso lwe-3D.

Ishishini eliphambili lale nkampani luphando lwe-airborne lidar, uphando lwe-laser ye-vehicular mobile scanning, uphando lwe-laser ye-laser yomhlaba, uphando lwe-aerial ye-aerial engabhalwanga, imveliso ye-4D yemveliso kunye nokwakhiwa kwe-database, ukwakhiwa kwe-3D ye-digital city, isisombululo se-3D yedijithali kunye nemveliso ye-animation ye-3D, Uphuhliso lwesoftware yeGIS, njl.njl. Iinkonzo zayo zibandakanya uhlolo olusisiseko kunye nokwenza iimephu, ucwangciso lwedolophu, ulawulo lomhlaba, ulwakhiwo lwesixeko esilumkileyo, impendulo kaxakeka yasezidolophini, ulongamelo oluhambahambayo, kunye novavanyo kunye nokwenza iimephu zohola wendlela, imibhobho ye-oyile kunye namashishini olondolozo lwamanzi.

Indawo yoVavanyo

ISithili saseYuncheng seSalt Lake sikumzantsi-ntshona wePhondo leShanxi, ekudibaneni kwamaphondo eQin, iJin kunye neYu kumbindi woMlambo oMthubi, odibanisa iXia County ngasempuma, iYongji kunye neLinyi ngasentshona, iZhongtiao Mountain kunye UPinglu noRuicheng emazantsi, kunye neJiwang Mountain kunye neWanrong, iJishan kunye neWenxi emantla. Ummandla weekhilomitha ezingama-41 ububanzi ukusuka empuma ukuya entshona, iikhilomitha ezingama-62 ubude ukusuka kumntla ukuya kumzantsi, kunye nommandla opheleleyo we-1237 yeekhilomitha zeekhilomitha.

Le projekthi ibandakanya iidolophu ezili-19 zizonke, iilali zolawulo ezingama-287, malunga neziza ze-130,000 zomhlaba, ezilinganisa indawo ye-100 square metres. Ngexesha leprojekthi, ngokuhambelana ngqongqo kunye neemfuno zamaxwebhu afanelekileyo kunye nemigangatho, iprojekthi iqhutywe uphando olunzulu lobunini bezindlu zasemaphandleni, imephu yeprojekthi ye-1: 500 yesikali semephu yemephu yeprojekthi, i-oblique photogrammetry, imodeli emithathu-ntathu, kunye nophuhliso lwesofthiwe ye-real estate. inkqubo yobhaliso kunye nesiqinisekiso. Isixa sekhontrakthi yeprojekthi ibingaphaya kwezigidi ezingama-40 zeeyuan.

UKhetho lweZixhobo

Kusetyenziswa iiseti ezimbini zezixhobo zokuhamba ngenqwelomoya kule projekthi. I-DJI M300 UAV ixhotyiswe ngekhamera ye-Chengdu Rainpoo D2 PSDK, kwaye i-M600 ixhotywe ngekhamera ye-DG3 PROS. Ukusetyenzwa kwangaphakathi usebenzisa i-30 yenkqubo ye-cluster ye-computer, ikhompyutha ixhotyiswe nge-2080TI okanye i-3080 yekhadi lemizobo, imemori ye-96G, iiseva ezintathu ze-AT (aerotriangulation) kunye ne-10T eqinile-state hard disk, umatshini we-node 256 i-solid-state hard disk.I-Rainpoo yikhamera ye-drone yokudweba imephu yekhamera. umenzi, kunye nekhamera ye-Rainpoo oblique isetyenziswa ngokubanzi kwiprojekthi yokuhlola i-aerial.Imifanekiso yezinga eliphezulu eliqokelelwe ngekhamera sisiqinisekiso somphumo we-3d modeling.

Isishwankathelo sezoPhapho kunye neFlight

Kule projekthi, ukuphakama koyilo kwakuyi-83 m, isisombululo somhlaba (GSD) sasiyi-1.3cm, kwaye umsebenzi wenziwa ngokuhambelana nesihloko / ukugqithiswa kwecala le-80 / 70% yemilinganiselo ye-cadastral eqhelekileyo. Indlela yabekwa kwicala elingasemantla-emazantsi kangangoko kunokwenzeka, kwaye ngaphezu kwezigidi ezi-4 zeefoto zoqobo zafunyanwa. Isithuba se-GCP simalunga neemitha ezili-150, kwaye iperiphery kunye nekona yendawo yokulinganisa yandise ubungakanani ngokufanelekileyo.

Ukwenziwa Kweenkcukacha

Ummandla weedolophana kwindawo yokuhlola ngokusisiseko malunga neekhilomitha ezili-square ze-0.3, ezinye zazo zifikelela ngaphezu kwe-1 square metres, kunye nenani leefoto malunga ne-20,000. Kukho ubunzima obuncinci bobugcisa ekuqhutyweni kwemodeli ye-oblique, eyona nto isebenzayo yombhobho. Imephu yeCadastral kunye nokuguqulwa kwemodeli ubukhulu becala amaqhinga olwandle lomntu. Imisebenzi efana ne-monomers yemodeli, ukugcinwa kwedatha, umboniso wolwazi kunye neminye imisebenzi iphathwa yisoftware ephuhliswe ngokuzimeleyo yinkampani yethu.

Ngenxa yenani elikhulu leefoto, i-M3D AT(Aerial Triangulation) isetyenziselwe ukusetyenzwa kwedatha. Zonke iiprojekthi zinemvelaphi efanayo kunye nobukhulu obufanayo bebhloko, ukwenzela ukuba ikhowudi yebhloko yeziphumo zeprojekthi nganye iyingqayizivele, ekulungele ukugcinwa kwemodeli kunye nokukhangela. Itheyibhile yendibaniselwano yebhloko iboniswe ngezantsi:

Ukuqukunjelwa kweProjekthi

Okwangoku, le projekthi ayizange igqitywe ngokupheleleyo, kwaye kuphela isheke elula kunye nezibalo zenziwa kwiziphumo eziphakathi kwemodeli. Uninzi lweengxaki zinokujongwa ngokukhupha kwakhona ishishini langaphakathi kunye nokuzoba umfanekiso kwakhona, ngelixa abambalwa kufuneka baphinde babhabhe.

Ngokubanzi, ukuchaneka kwemodeli kulungile, kwaye izinga lokuphumelela liphezulu kune-95%. Ngokwemodeli, imodeli ye-DG3 ingcono kancinane kunemodeli ye-D2 phantsi kweemeko ezifanayo. Iingxaki zemifuziselo ikakhulu zibandakanya la manqaku alandelayo: ukukhululeka komhlaba okubangelwa kukudibana kweqondo okanye ukusonjululwa akuhambelani neemfuno, imozulu yemvula okanye inkungu ebangelwa kukungakhanyisi ngokwaneleyo okanye ukubonakala.

Umfanekiso wekhusi weModeli

Ngaphambi kokubhabha, izixhobo ze-RTK zisetyenziselwa ukulinganisa ulungelelwaniso oluchanekileyo lweendawo zeempawu zomhlaba (ezifana nokuwela i-zebra, imigca yokumakisha, iithagethi zohlobo lwe-L kunye namanye amanqaku abalulekileyo) kwindawo yokulinganisa njengeendawo zokujonga ukujonga ukuchaneka kwemodeli kwinqanaba lamva. . Inkqubo yokulungelelanisa i-CS2000 isetyenziselwa indawo yokukhangela kunye nobude obufanelekileyo beparamitha isetyenziselwa ukuphakama. Oku kulandelayo yimeko yomlinganiselo wethu weempawu. Ngenxa yokunqongophala kwendawo, sikhetha kuphela ezimbalwa zazo ukuba sibonise.

Intshayelelo yeNkqubo yeZiphumo

Isetyenziselwa ikakhulu ukudweba imephu ye-cadastral ye-real estate, ukuncedisa uphando lwentsimi, ukwakhiwa kwedatha, njl.

Imodeli ye-Oblique yinkqubo yangaphambili yokulinganisa indawo yokuhlala, echaphazela ngokuthe ngqo ishedyuli yeprojekthi. Ikhamera yeRainpoo esiyikhethileyo inika iprojekthi yethu inkxaso eyomeleleyo. Sisebenzise izixhobo ezibini ukuchaphazela iprojekthi engaphezu kwezigidi ezingama-40 zeeyuan. Okokuqala, ukusebenza kakuhle kuphezulu kwaye uzinzo lomelele. I-M300 ixhotyiswe ngekhamera ye-D2, enokuqonda ukusebenza okukodwa, kwaye inkqubo yokusebenza ayinangxaki. Emva koko, idatha ilungile, malunga ne-30% yeefoto ezingasebenziyo zingasuswa, ukuphucula ukusebenza kakuhle komsebenzi weofisi, i-AT (i-aerial triangulation) izinga lokupasa liphezulu, ngokusisiseko zonke zinokudlula kanye, ekugqibeleni, umgangatho wemodeli uphezulu. , zombini ukuchaneka kwemodeli kunye nomgangatho wemodeli unomsebenzi omhle.
