LiDAR vs Photogrammetry: Ndeipi Tekinoroji Inonyatsokodzera Ongororo Yenzvimbo?
Ukabhururuka pamusoro penzvimbo ine miti yakawanda uchishandisa drone ye-photogrammetry pamwe ne-drone ine LiDAR, unowana mamodheru maviri akasiyana zvachose evhu. Photogrammetry inoona misoro yemiti chete, asi mwaranzi yelaser ye-LiDAR inopinda nepakati pemashizha kuti iongorore pasi pevhu chairo. Musiyano mukuru uyu ndiwo unosarudza tekinoroji inodiwa nebasa rako.
Zvose LiDAR ne-photogrammetry zvinogadzira mamodheru e-3D enzvimbo kubva pane data remumhepo, asi nzira yekutora data yakasiyana zvakanyanya. Photogrammetry inovaka modheru ye-3D kubva pamifananidzo inobatana. LiDAR inopfura mwaranzi yelaser zviuru zvakawanda pasekondi yoyera nguva yekudzoka kwayo kuti izive kukwirira kwevhu chairo.
Ona Kupinda Pasi Pemiti Kwelaser Pakarepo
LiDAR vs Photogrammetry Pasi Pemiti
Enzanisa Huwandu hwe-Point Cloud
Musiyano we-Point Cloud Density
Wana Chiyero Pakati Pemutengo Nekururama
Mutengo vs Kururama Kwebasa
Tafura Yekuenzanisa Zvakazara
| Chinhu Chekutarisa | Photogrammetry | LiDAR |
|---|---|---|
| Kupinda pasi pemiti | Kwete, inotora chete pamusoro panovonekwa | Hongu, laser inosvika pasi pevhu |
| Chiyero chemutengo | Mushoma (₹500-1,500/acre) | Kapetwa ka-2 kusvika ka-3 kudarika photogrammetry |
| Nzvimbo yakakodzera | Minda yakachena isina miti yakawanda | Masango makuru, makwenzi nemakomo |
| Data rinobuda | Mepu ye-Orthomosaic + DTM | Point cloud yakazara ine chikamu chevhu |
Panzvimbo dzakachena dzisina miti mizhinji, photogrammetry inopa kururama kwakafanana pamutengo wakaderera zvikuru. Chengetera LiDAR kunzvimbo dzine masango makuru uko makamera asingakwanisi kuona pasi pevhu.
Photogrammetry inotora mufananidzo wezvinovonekwa. LiDAR inoyera chaizvo zviripo ipapo, kunyangwe zvakavanzika.
Kusarudza Tekinoroji Yakakodzera
Sarudza tekinoroji maererano nemamiriro enzvimbo kwete nebhajeti chete. Chikwata chedu che- drone survey chinoongorora huwandu hwemiti chisati chakurudzira nzira, uye gwaro rega rega re- LiDAR scan rinosanganisira data revhu rakanyatsorongeka.
Hauna chokwadi kana nzvimbo yako ichida LiDAR?
Tiudze nezvemhando yenzvimbo yako nemamiriro emiti, tichakukurudzira tekinoroji yakanyanya kunaka.
Mibvunzo Inowanzo Bvunzwa
LiDAR inoshandisa laser inopinda mumiti kuyera ivhu, asi photogrammetry inoshandisa mifananidzo.
Kwete. Panzvimbo dzakachena, photogrammetry inopa mhedzisiro yakafanana nemutengo wakaderera.
Michina ye-LiDAR inodhura zvikuru, inoburitsa data rakakura kwazvo uye inoda mapurogiramu akakosha ekuongorora.
Kwete. Photogrammetry inovimba nechiedza chezuva saka haikwanisi kuona ivhu riri pasi pemiti.
LiDAR inoburitsa point cloud yakazara uye yakaenzana zvikuru kunzvimbo dzine masango.
Hongu, sezvo LiDAR ichiburitsa chiedza chayo chelaser, inoshanda zvakanaka kunyangwe murima guru.
Masango makuru, nzvimbo dzine makwenzi akakora nemakomo akaoma kuongorora.
Photogrammetry inongoratidza misoro yemiti chete. Kuti uwane ivhu chairo (DTM), LiDAR inodiwa.
Hongu, ma-GCP akayerwa ne-DGPS anodiwa kuti ave nechokwadi chekururama kwebasa.
Photogrammetry inowanzokurumidza kugadzirwa nekuti mafaira ayo madiki zvichienzaniswa ne-LiDAR.
Nhamba iyi ndeyemibvunzo yemapurojekti chete. Ndapota musabata nezvekudzidziswa kana mabasa.
