Traditional zimachititsa chilumbachi vrs. LiDAR. Zowona, nthawi ndi ndalama.

Kodi kugwira ntchito ndi LiDAR kungakhale kolondola kwambiri kusiyana ndi malo ochiritsira? Ngati amachepetsa nthawi, ndi chiani?

Nthawi zasinthadi. Ndimakumbukira pamene Felipe, wofufuza malo amene ankagwira ntchito yolemba ntchito, anabwera ndi kabuku ka 25 ndi masamba a magawo awiri kuti apange mapu ozungulira. Sindinakhale nthawi yolemba mapepala koma ndikukumbukira ndikuchita ndi AutoCAD popanda kugwiritsa ntchito Softdesk. Kotero ine ndinalankhula ndi Excel kuti ndidziwe kutalika kwake kukwera pakati pa mapiri awiri, ndipo mfundo izi zinawayika mu zigawo za mitundu yosiyana ndi mitundu, kuti potsiriza azigwirizana nawo ndi polylines zomwe zinatembenuzidwa kukhala ma curves.

Ngakhale ntchito ya ndende inali yopenga, sinali yofanana ndi ntchito yopanga luso, ngati mukufuna kukhala ndi deta yokwanira kuti mutenge chitsanzo chovomerezeka pamene altimetry inali yopanda pake. Kenaka panafika SoftDesk, antecedent wa AutoCAD Civil3D kuti kabungwe losavuta ndi Felipe anali mu maphunziro anga omwe amaphunzira kugwiritsa ntchito malo onse, zomwe zinachepetsa nthawi, zinawonjezera kuchuluka kwa mfundo komanso ndithu molondola.

Sewero drones pofuna kugwiritsidwa ntchito ndi anthu amaswa maulamuliro atsopano, pansi pa lingaliro lofanana: Kukaniza kusintha njira zamakono nthawi zonse kumachepetsa kuchepetsa ndalama ndi kutsimikizirika molondola. Kotero ife tipenda mu nkhani ino ziganizo ziwiri zomwe ife tazimvapo apo:

1 Hypothesis: Kulemba zolemba ndi LiDAR kumachepetsa nthawi ndi mtengo.

Zophatikiza 2: Kulemba malo ndi LiDAR kumatanthauza kutaya mwachindunji.

Nkhani yoyesera

Magaziniyi POB anakhazikitsa ntchito yomwe ntchito idakonzedwa pa deta yosonkhanitsa deta, pogwiritsira ntchito njira zamakono pamakilomita a 40. Mwapadera, mu ntchito yachiwiri masiku angapo pambuyo pake adapangidwa pogwiritsa ntchito zojambulajambula ndi LiDAR pamakilomita a 246 a damu lomwelo. Ngakhale kuti zigawozo sizinali zofanana, chigawo chofananacho chinafanizidwa ndi kufanana ndi zofanana.

Zojambula zojambula

Kafukufukuyu anagwiritsidwa ntchito m'magawo ena pa 30 mamita, pofanana ndi malo omwe alipo. Mfundo zozengereza zinatengedwa pamtunda wochepa kuposa mamita 4.

Kuwonetseratu ntchito ndi zida za geodetic network, zomwe zinatsimikiziridwa ndi GPS geodetic motsatira nkhwangwa, ndipo kuchokera izi zigawo zozungulira zinayambitsidwa pogwiritsa ntchito magulu owonetsera malo ndi RTK. Zinali zofunikira kutenga mfundo zina pa malo apadera a kusintha kwa malo otsetsereka ndi mawonekedwe kuti zitsimikizidwe mofanana ndi mtundu wa digito.

kukonza zojambulajambula

Kusiyanitsa kusiyana pakati pa zidziwitso ndi ma coordinates omwe apezeka ndi GPS ndiwo omwe akuwonetsedwa patebulo, kutsimikizira kuti kukweza kosinthika ndi kolondola kwambiri.

Chiwerengero chokhazikika Osachepera chotsalira
yopingasa 2.35 masentimita. 1.52 masentimita.
ofukula 3.32 masentimita. 1.80 masentimita.
Mizere itatu 3.48 masentimita. 2.41 masentimita.

Kafukufuku wa LiDAR

Izi zinachitika ndi Autonomous Unit ikuuluka pamtunda wa mamita 965, ndi nambala ya mapu a 17.59 pa mita imodzi. Anapezanso mfundo zodziwika za 26 ndipo anaziphwanya motsutsana ndi 11 mfundo zina zoyamba zomwe zinawerengedwa ndi GPS geodetic.

Ndi mfundo izi za 37 kusintha kwa deta ya LiDAR. Ngakhale kuti sizinali zofunikira kuyambira m'makonzedwe otengedwa ndi UAV omwe ali ndi GPS yolandila ndi kuyang'aniridwa ndi malo osungirako, amapezeka nthawi zonse osachepera satellites a 6 akuwonekera ndipo POPOP yaying'ono ku 3. Maulendo ku sitima yapamunsi sanali wamkulu kuposa makilomita a 20.

Mndandanda wa mfundo zowonjezera za 65 zomwe zatchulidwa kuti zitsimikizire kulondola kwa deta ya LiDAR. Potsata mfundo izi, tinapeza zotsatila zotsatizanazi zinali:

M'mizinda: 2.99 masentimita. (Mfundo za 9)

Kumunda kapena udzu wochepa: 2.99 masentimita. (Mfundo za 38)

Kumtunda: 2.50 masentimita. (Mfundo za 3)

Mu zitsamba kapena udzu wamtali: 2.99 masentimita. (Mfundo za 6)

kukonza zojambulajambula

Chithunzicho chimasonyeza kusiyana kwakukulu kwa kuwerengeka pakati pa mfundo zomwe zinatengedwa ndi LiDAR motsutsana ndi zigawo za mtanda zomwe zimayikidwa pa katatu wobiriwira.

Kusiyanasiyana pa Kukonzekera

Zomwe akupezazi sizoposa zokondweretsa, zotsutsana ndi lingaliro lakuti kafukufuku wa LiDAR sakufika pa ndondomeko ya kachitidwe kafukufuku. Zotsatirazi ndi RMSE (Mizu yeniyeni yolakwika mapiko), zomwe ndizolakwika pampakati pakati pa deta yolandidwa ndi mfundo zolembera.

Zojambula zojambula LiDAR kukweza
1.80 masentimita. 1.74 masentimita.

Kusiyana kwa Nthawi

Ngati izi zadodometsa ife, tawonani zomwe zinachitika panthawi ya kuchepetsa nthawi pakati pa njira ya LiDAR ndi njira yachikhalidwe:

Kusonkhanitsa deta kumunda ndi LiDAR kunali 8% chabe.

  • Ntchito ya Cabinet ndi 27% chabe.
  • Kuphatikizira masewera + ndege + LiDAR maofesi a mahatchi motsutsana ndi dera ladzidzidzi + Malo ovomerezeka a kabati, LiDAR imangofuna 19%.

kukonza zojambulajambula

Zotsatira zake, maola a 123 a ntchito pa kilomita imodzi yokhala ndi malo ochiritsira amachepetsedwa kukhala maola 4 okha pa kilomita.

Kuonjezera apo, ngati zonse zomwe zatengedwa zikugawanika pakati pa nthawi yomwe ikugwiritsidwa ntchito ndi ndondomeko ya kabati, njira yowonjezera inapezera mfundo za 13.75 pa ora, motsutsana ndi mfundo za 7.7 milioni pa ola la LiDAR.

Kusiyana kwa Nthawi

Zomwe zimagwiritsidwa ntchito ndi zida zamakono zamakono, ndi zithunzithunzi zomwe zimagwiritsa ntchito mfundozo, tiyerekeze kuti ntchitoyo iyenera kukhala yotsika mtengo. Koma pakuchita, kuchepetsa nthawi ndi ndalama zowunikira zomwe zikutanthawuza malo ozolowereka, The mtengo komaliza kwa makasitomala a 246 71 makilomita anali ndi LiDAR% poyerekeza ndi mtengo okwana 40 makilomita ochiritsira zimachititsa chilumbachi.

Zikuwoneka zosadabwitsa, koma mtengo uliwonse pa kilomita yayitali ndi LiDAR inali 12% poyerekezera ndi malo ochiritsira.

Pomaliza

Kodi zimachititsa chilumbachi kwathunthu m'malo mwa Traditiona LiDAR zimachititsa chilumbachi. Konse, chifukwa ntchito ndi LiDAR nthawi wapatuka zimachititsa chilumbachi kuti checkpoints, koma Ndizachidziwikire kuti ndi ubwino onse a mtengo, mankhwala khalidwe ndi nthawi ntchito ndi LiDAR amapanga zotsatira ndi pafupi zofanana mwatsatanetsatane zimachititsa chilumbachi ochiritsira.

Padzakhala nthawizonse zopindulitsa ndi zowonongeka; kutsimikizirika kwapamwamba kwa malo ochiritsira omwe ali ochiritsira, ndi zovuta za kupempha chilolezo cholowa pakhomo lapadera, zoopsa za malo pamalo osasinthasintha, zosowa zapakati pa udzu ndi zovuta ... ndizopenga. Zoonadi, kuchulukanso kwa nkhalango kumakhudzanso kuipa kwa LiDAR, komanso sizomwe zimayendera mgwirizano pakati pa mapulani ang'onoang'ono.

Pomalizira, tikukondwera kudziwa momwe zipangizo zamakono zasinthira kufika pakufika kwa mapulojekiti akuluakulu monga omwe anaukitsidwa, ndikofunikira kukhala ndi malingaliro otseguka komanso okonzeka kusankha njira zatsopano zowonetsera zojambulajambula.

8 Iyankha ku "Zithunzi zapamwamba zachikhalidwe. LiDAR Kulondola, nthawi ndi mtengo wake. ”

  1. Mmawa wabwino ... abwenzi .... kunena za kugwiritsa ntchito drones kuti apange kafukufuku ... .wowo angakhale mu sensa ndi / kapena zipangizo zomwe zimasonyezedwa kuti zikwezere malo ambiri (1000 Ali kapena zambiri) ndi zomera zowirira kapena zowonongeka? kumene kupeza kuli kovuta kwambiri.
    Nkhani yabwino !!

  2. mfundo zabwino kwambiri ndipo zimandipatsa view bwino njira imeneyi, komanso anapeza kuti chifukwa chopanga ndi chida chachikulu, koma zinachitikadi kuchita ochiritsira yoyeza ndi okwerera okwana amatenga zofunika kwambiri zofuna kusintha ambiri mizere Makhalidwe ndi miyeso yomwe imapereka udindo wofunikira pa polojekiti yoperekera pamene magawo osachepera 0.05m a zolakwika amafunikira. moni
