Kulondola kwa Kafukufuku wa Drone: GCPs, PPK ndi Zotsatira Zosakwana 5cm
Popanda kukonza kulikonse, kuwuluka kwa drone wamba kumatha kupatuka ndi mamita angapo kuchokera pamalo enieni, monga kusakhazikika kwa GPS pafoni yanu. Njira ziwiri zapadera zimasandutsa deta yosakonzedwayo kukhala ntchito ya engineering yolondola mpaka masentimita ochepa chabe: Malo Owongolera Pansi (GCPs) ndi kukonza kwa PPK (Post-Processed Kinematic). Onerani momwe zimagwirira ntchito pachiwonetsero chili m'munsichi.
Malo owongolera pansi amamangiriza deta yonse ya ndege ku ma coordinate a DGPS otsimikizika pansi. Pakadali pano, kukonza kwa PPK kumatsuka deta ya komwe drone inali mutawuluka pogwiritsa ntchito deta ya satellite base station. Zonse pamodzi, zimabweretsa zotsatira zodalirika zomwe makampani omanga ndi maofesi a nthaka amatha kudalira kwathunthu.
Onani Momwe Kuwuluka kwa Drone Kumamangirizidwa ku Malo Oyang'anira Pansi
Makanema a Njira ya Ndege ndi Kutseka kwa Ma GCPs

Chifukwa Chake Njira Zonse Ziwiri Zili Zofunika Pamodzi
| Luso la Sayansi | Zomwe Zimakonza | Zotsatira Zake |
|---|---|---|
| Malo Owongolera Pansi (GCPs) | Amamangiriza deta yonse ku ma coordinate a DGPS oyesedwa pansi | Amachotsa zolakwika zosuntha malo pamalo onse ogwirira ntchito |
| Kukonza kwa PPK (Mutawuluka) | Amatsuka cholemba cha malo a drone ndi deta ya satellite base station | Amawonjezera kulondola kwa mfundo iliyonse popanda kufunikira ma GCPs ochulukirapo |
| Kuphatikiza Zonse Ziwiri | Kukhazikika pansi kwathunthu + kusanja bwino mfundo iliyonse | Kupeza kulondola kosakwana 5cm (Sub-5cm) paulendo wokonzekera bwino |
Kukonza kwa PPK kumatha kuchepetsa kuchuluka kwa ma GCPs omwe amafunika pamalo aakulu. Komabe, pa ntchito za malire a zamalamulo, kufunika kwa ma GCPs sikungachotsedwe kwathunthu.
Deta yosakonzedwa ya drone imatha kuwoneka yabwino pamaso, koma sikhala yolondola mpaka malo owerengera pansi atatsimikizira malo ake enieni.
Kodi Izi Zikutanthauza Chiyani pa Ntchito Yanu
Ngati polojekiti yanu ikufuna deta ya malire yovomerezeka mwalamulo ndi mu engineering, musalandire deta ya drone popanda kutsimikizira kuchuluka kwa GCP ndi kukonza kwa PPK. Njira yathu ya kupanga mapu a drone imatsatira miyezo iyi mosamalitsa, ndipo deta iliyonse imayang'aniridwa motsutsana ndi chowonadi cha pansi pa topography.
Mapu a orthomosaic owoneka bwino samatsimikizira kulondola kwa malo. Nthawi zonse pemphani lipoti lolondola lomwe likuwonetsa zolakwika pamalo oyezera odziyimira pawokha (Checkpoints).
Kodi mukufuna kafukufuku wolondola komanso wotsimikizika wa polojekiti yanu?
Pemphani chitsanzo cha lipoti lolondola kuchokera kwa ife musanasankhe kampani iliyonse ya drone.
Mafunso Omwe Amafunsidwa Kawirikawiri (FAQ)
GCP ndi cholembera pansi chomwe chimayesedwa bwino ndi DGPS kuti chigwirizanitse zithunzi zamlengalenga ndi ma coordinate enieni a dziko lapansi.
PPK imatanthawuza Post-Processed Kinematic, njira yomwe imakonza deta ya GPS ya drone mutawuluka pogwiritsa ntchito deta ya satellite base station.
Popanda ma GCPs, GPS ya drone imatha kupatuka ndi mamita 2 mpaka 5, zomwe sizoyenera ntchito za engineering.
PPK imachepetsa chiwerengero cha ma GCPs ofunikira, koma ochepa amafunikabe kutsimikizira kulondola komaliza.
Pamalo apakati anthawi zonse, ma GCPs 4 mpaka 6 ogawidwa bwino ndi okwanira.
Ndi ma GCPs oyenera komanso PPK, kulondola kosakwana 5cm (sub-5cm) kumatheka mosavuta.
Pemphani lipoti lomwe likuwonetsa zolakwika pamalo odziyimira pawokha (Checkpoints), osati kungoyang'ana mapu omalizidwa okha.
Inde, ma GCPs ayenera kugawidwa mofanana m'makona, m'mbali, ndi pakati pa malo onse.
Zonse zimagwiritsa ntchito ma satellite base station, koma RTK imakonza nthawi yomweyo pakuwuluka pomwe PPK imakonzedwa mutawuluka kuofesi.
Kusiya ma GCPs kumasunga nthawi ndi ndalama pamunda, koma kumatsitsa kwambiri kulondola kwa zotsatira.
Nambalayi ndi ya mafunso okhudza mapulojekiti okha.
