LiDAR vs Photogrammetry: Ni Ryarihe Koronabuhanga Ribereye Umushinga Wawe?
Iyo ugurukije drone ya photogrammetry na drone irimo LiDAR hejuru y'ubutaka buriho amashyamba, ubona ubutaka bubiri butandukanye rwose. Photogrammetry ibona gusa ibisonga by'ibiti, mugihe imirasire ya laser ya LiDAR yinjira mu myanya y'amashami igapima ubutaka nyabwo buri hasi. Ubu butandukanye bw'ingenzi nibwo bugena ikoranabuhanga rikenewe.
Zose LiDAR na photogrammetry zikora amashusho ya 3D y'ubutaka zifashishije amakuru yo mu kirere, ariko uburyo zikusanya amakuru buratandukanye cyane. Photogrammetry yubaka 3D binyuze mu guhuza amafoto menshi. LiDAR yo yohereza ibipimo bya laser ibihumbi amagana ku isegonda ikapima igihe bifata kugaruka kugira ngo imenye ubutumburuke nyakuri bw'ubutaka.

Shaka Impuzandengo y'Igiciro n'Ubwiza
Igiciro vs Ubwiza bw'Ibipimo
Imbonerahamwe y'Igereranya Rirambuye
| Ikintu | Photogrammetry | LiDAR |
|---|---|---|
| Kwinjira mu biti | Oya, ifata gusa ibigaragara hejuru | Yego, laser igera ku butaka hasi |
| Urwego rw'igiciro | Birahendutse (₹500-1,500/acre) | Kwikuba inshuro 2 kugeza kuri 3 |
| Ubutaka bubereye | Ahantu hakinguye hatari ibiti | Amashyamba y'inzitane n'imisozi miremire |
| Amakuru atangwa | Ikarita ya Orthomosaic + DTM | Point cloud icucitse irimo amakuru y'ubutaka |
Ku butaka bukinguye budafite ibiti byinshi, photogrammetry itanga ubwiza bungana ku giciro gito cyane. Koresha LiDAR by'umwihariko ku mashyamba aho kamera zisanzwe zidashobora kubona ubutaka hasi.
Photogrammetry ifotora ibyo ibona. LiDAR ipima neza ibihari nyakuri, n'iyo byaba byihishe munsi y'amashyamba.
Guhitamo Ikoranabuhanga Riboneye
Hitamo ikoranabuhanga ukurikije imiterere y'ubutaka aho kuba ingengo y'imari gusa. Itsinda ryacu rya drone survey risuzuma ubucucike bw'ibiti mbere yo kugira inama, kandi buri raporo ya LiDAR scan irimo amakuru y'ubutaka asobanutse neza.
Ntubwo uzi neza niba umushinga wawe ukeneye LiDAR?
Tusangize ubwoko bw'ubutaka n'imiterere y'ibiti, tuzakugira inama y'ikoranabuhanga ryiza cyane.
Ibibazo Bikunze Kubazwa
LiDAR ikoresha laser yinjira mu biti igapima ubutaka, mugihe photogrammetry yishingikiriza ku mafoto.
Oya. Ahantu hakinguye hatari ibiti, photogrammetry itanga umusaruro mwiza ku giciro gito cyane.
Ibikoresho bya LiDAR birahenze cyane, bitanga amakuru menshi cyane kandi bikenera porogaramu zihariye zo kuyatunganya.
Oya. Photogrammetry yishingikiriza ku rumuri rusanzwe, bityo ntishobora kubona ubutaka munsi y'amashyamba.
LiDAR itanga amakuru ya point cloud acucitse kandi angana neza cyane cyane mu mashyamba.
Yego, kuko LiDAR yohereza urumuri rwayo rwa laser, ikora neza no mu mwijima w'icuraburindi.
Amashyamba y'inzitane, udusozi turiho ibihuru n'ahantu h'imisozi igoye gupima.
Photogrammetry izerekana gusa hejuru ku biti. Kugira ngo ubone ubutaka nyabwo (DTM), LiDAR irakenewe.
Yego, amanota ya GCP yapimwe na DGPS aracyakenewe kugira ngo hemezwe neza ubunyangamugayo bw'ibipimo.
Photogrammetry itunganywa vuba kuko ingano y'amadosiye yayo ari nto ugereranyije na LiDAR.
Uyu murongo wagenewe gusa ibibazo by'imishinga y'ubucuruzi. Nyamuneka ntimuhamagare mushaka akazi cyangwa imyitozo.
