Ukuri kw'Ubushakashatsi bwa Drones: GCPs, PPK n'Ibisubizo biri munsi ya 5cm
Nta gukosora uko ari ko kose, kuguruka kwa drone bisanzwe bishobora gutandukana na metero nyinshi n'ahantu nyakuri, kimwe n'ikosa rya GPS ya telefone yawe. Tekiniki ebyiri zihariye zihindura ayo makuru adakusanyije neza mo ibipimo byo ku rwego rw'ubwubatsi bifite ukuri kw'isengeri nke: Utubuto two Kugenzura ku Butaka (GCPs) no gukosora kwa PPK (Post-Processed Kinematic). Reba uko bikora mu buryo bugaragara hasi aha.
Utubuto two kugenzura ku butaka buhuza amakuru yose yo kuguruka n'impushya za DGPS zemejwe ku butaka. Hagati aho, gukosora kwa PPK kunoza inyandiko y'aho drone iherereye nyuma yo kuguruka hakoreshejwe amakuru ya sitasiyo y'icyogajuru. Byombi bifatanyirize hamwe bitanga ibisubizo byizewe byuzuye abatunganya inyubako n'ubutaka bashobora kwishingikirizaho.
Reba Uko Kuguruka kwa Drone Gufatanya no Kugenzura ku Butaka
Icyitegererezo cy'Inzira yo Kuguruka no Gufunga Utubuto twa GCPs
Gerageza Wowe Ubwawe: Kurura Kugira ngo Urebeko Gukosora kwa PPK Gukora
Icyitegererezo cyo Guhuriza hamwe Utubuto (Point Cloud)
Impamvu Tekiniki Zombi Zikenewe Hamwe
| Tekiniki | Icyo Ikosora | Ibisubizo Bisanzwe |
|---|---|---|
| Utubuto two Kugenzura ku Butaka (GCPs) | Ihuza amakuru yose n'impushya za DGPS zapimwe ku butaka | Ikuraho amakosa yo kwimuka kw'aho ikibanza giherereye |
| Gukosora kwa PPK (Nyuma yo Kuguruka) | Inoza inyandiko y'aho drone iherereye n'amakuru ya sitasiyo y'icyogajuru | Yongera ukuri kwa buri kabuto idakeneye GCPs nyinshi cyane |
| Guhuza Zombi | Guhama ku butaka busesuye + kunoza neza buri kabuto | Kugera ku kuri kuri munsi ya 5cm (Sub-5cm) ku ngendo zateguwe neza |
Gukosora kwa PPK gushobora kugabanya umubare wa GCPs ukenewe ku bibanza binini. Icyakora, ku mirimo yerekeye imbibi zemewe n'amategeko, gukenera GCPs ntibishobora gukurwaho burundu.
Amakuru ya drone adakosowe ashobora kugaragara neza ku maso, ariko ntabwo aba ari ukuri kugeza igihe ikimenyetso cyo ku butaka cyemeje aho aherereye nyakuri.
Ibi Bivuze iki ku Mushinga Wawe
Niba umushinga wawe ukeneye amakuru y'imbibi yizewe mu buryo bw'amategeko na tekiniki, ntiwemere amakuru ya drone udahamije ubwinshi bwa GCP no gukoresha PPK. Uburyo bwacu bwo gupima hakoreshejwe drone bukurikiza aya mabwiriza bikomeye, kandi buri makuru yose agereranywa n'ukuri kw'imiterere y'ubutaka topography.
Ikarita ya orthomosaic isa neza ntigaragaza ko ifite ukuri ku bipimo. Buri gihe saba raporo y'ukuri igaragaza amakosa ku tubuto two kugenzura twigenga (Checkpoints).
Ukeneye amakuru y'ipima yizewe afite ukuri kwemejwe ku mushinga wawe?
Saba urugero rwa raporo y'ukuri mbere yo guhitamo sosiyete iyo ari yo yose yo gupima.
Ibibazo Bikunze Kubazwa (FAQ)
GCP ni ikimenyetso gipimwa neza ku butaka hakoreshejwe DGPS kugira ngo gihuze amafoto yo mu kirere n'impushya nyakuri z'isi.
PPK bivuze Post-Processed Kinematic, uburyo bukosora amakuru ya GPS ya drone nyuma yo kuguruka hakoreshejwe amakuru ya sitasiyo y'icyogajuru.
Nta GCPs, GPS ya drone ishobora gutandukana na metero 2 kugeza kuri 5, ibyo bikaba bidakwiriye imirimo y'ubwubatsi.
PPK igabanya umubare wa GCPs ukenewe, ariko nkeya ziba zigikenewe kugira ngo hemezwe ukuri kwa nyuma.
Ku kibanza gisanzwe kiringaniye, GCPs 4 kugeza kuri 6 zikwirakwijwe neza ziragije.
Hamwe na GCP zikwiriye na PPK, ukuri kuri munsi ya 5cm (sub-5cm) kugerwaho byoroshye.
Saba raporo igaragaza amakosa ku tubuto twigenga (Checkpoints), aho kureba gusa ikarita yarangiye.
Yego, GCPs zigomba gukwirakwizwa kimwe mu nguni, ku mpera, no hagati mu kibanza.
Byombi bikoresha amakuru ya sitasiyo y'icyogajuru, ariko RTK ikosora mu gihe cyo kuguruka naho PPK igakosorwa nyuma mu biro mu buryo butuje.
Gusimbuka GCPs bizigama igihe n'amafaranga ku murima, ariko bigabanya cyane ukuri kw'ibisubizo bitangwa.
Uyu murongo wagenewe gusa ibibazo by'imishinga y'ubucuruzi.
