Ukuthandwa kanye nokutholakala kwezimoto ezingenamikhawulo ze-Aerial Vehicles (UAV) kuhlose izimboni eziningi ngokunciphisa izindleko kanye nokwanda kwabasebenzi ukuphepha. Kepha kuthiwani ngomphakathi wesayensi? Amakhulu, uma kungenjalo izinkulungwane, zososayensi abazimele kanye namanyuvesi emhlabeni wonke zisebenzisa lezi zi-UAV ukwenza izivivinyo eziyinkimbinkimbi zesayensi ngezindlela ezintsha.
Sivame ukugxila ekusetshenzisweni kwezimboni nezentengiso ze-UAV, kepha isayensi ehlanzekile futhi zizuza ngokutholakala nokutholakala kwezindiza lapho amabhajethi eqinile nesikhathi sokuqedela izivivinyo kubalulekile.
Isibonelo, ososayensi abaningana basePoland basebenzisana nocwaningo olunzulu lokuguguleka kwasogwini, kusetshenziswa ubuchwepheshe obusha obuningana obunjenge-lidar yomoya kanye ne-bateymetry.
I-Pawel Tysiac ne-Rafal Ossowski ye-Faculty of Civil and Envirol Engineering e-GDAnsk University of Technology University of Geomorpology kanye ne-geology ye-University of GDAnsk, sebeqedile ku Ukutadisha okuphelele kokuguguleka kwengxenye yogu lwasePoland (ngokwengeziwe ngokwengeziwe, ukunwetshwa kwamamayela ayi-1 eSouthern Baltic.
Leli phepha linesihloko esithi "Ukuhlola Usogwini lwamaCliff Cliff usebenzisa idatha ye-Drone ne-Orthophoto kanye ne-bathyymetric Lidar ku-Google Earth Engine". Kwashicilelwa emibikweni yesayensi, ngoJanuwari 2025 futhi kuyisibonelo esiyingqayizivele sokusetshenziswa kobuchwepheshe obusha ukuqoqa idatha ebaluleke kakhulu ukuqonda indlela yemvelo.
Sibe nethuba lokukhuluma noPawel Tysiac, ongomunye wababhali afunda, ukuze baqonde kangcono umthelela we-drones kanye ne-limistar kuphrojekthi yabo.
"Izindlela zendabuko zokuqapha ukuguguleka kweCliff zivame ukudinga umsebenzi wensimu ezisebenza kanzima kanye nokubala okuyinkimbinkimbi kokusatshalaliswa kwamaphoyinti wendawo esebenzisa amasu wendabuko endawo," kusho uPawel. "Ngokuphambene, intuthuko yakamuva yokuzwa okukude nokufunda ngomshini inikela ngezindlela ezintsha zokuhlola ukonakaliswa kwe-cliff ngokunemba okukhulu nokunemba."
Ukonakaliswa kosogwini kudonsele ukunakwa kohulumeni nososayensi emhlabeni wonke njengoba inani lezinhlekelele zemvelo likhuphuka futhi inhlekelele ngayinye ibangela ukulimala okwengeziwe kwabaningi kanye nezindawo.
"Kuleli phepha, sisebenzisa igama elithi 'Bluff Dealcoration' kabanzi. Sichaza ukuthi umthelela ophelele wokugcina wezinguquko ezinhlotsheni ezinqolobaza ezikhulayo ezibangelwa ukuthuthuka okukhulu kanye nemithelela yawo, okufana nokuqina komhlaba, amaphutha, ukufula, futhi Udoti, "kusho uPawel. "Ngokusekelwe kulokhu, isisekelo esibalulekile salolu cwaningo ukuthi i-electromagnetic wave ibonakale ezindaweni ezithintekayo ngokuwohloka kokonakaliswa.
Namuhla, ukuzwela okukude kuyindlela ejwayelekile yokuqapha izindawo ezisogwini. Ngokusebenzisa izinhlobo ezahlukahlukene zezithombe nedatha eqoqwe kuma-satellite, amapulatifomu asolwandle, kanye nezinzwa ezisekelwe emhlabathini, abacwaningi bangathola imininingwane enemininingwane futhi esesikhathini esesikhathini mayelana nezindawo ezisogwini. Izithombe ze-Time Resolution Frame Izithombe zivumela ukubonwa kwezinguquko ezingozini ezisogwini ngokuhamba kwesikhathi futhi kusize ukukhomba izindawo ezithinteka kakhulu izinhlekelele zemvelo. Kulokhu, ababhali basebenzise izithombe zendiza, ezihlinzeka ngezithombe eziphezulu kwezinqumo ezilusizo ekuqhathaniseni okunemininingwane ngaphambi nangemva kokulandela. Kodwa-ke, kunenkinga yezikhathi ezahlukahlukene zokukhanyisa ezithombeni, okuholela ezintweni ezahlukene okufanele zicutshungulwe. Ngokuya kwezithombe, izindiza zidinga ukwenziwa ngaphansi kwezimo ezifanayo, kepha kusenezingqinamba ezithile ngokuhlukahluka konyaka kulokhu.
UPawel uthi: "Sinqume ukusebenzisa i-lidar njengenye indlela yokubhekana nokushintsha kwezimo zokukhanyisa," kusho uPawel. "Idatha yeLidar ibalulekile ekulinganiseni izinguquko eziphezulu zasogwini ngokunemba okuphezulu, isiza ukuhlunga idatha kusuka ezimigcemeni noma ngamaphoyinti akhethekile. Lezi zinhlobo ezisiza ukuzoqonda ukusatshalaliswa kwendawo yokuguguleka."
Inkinga yavela ngoba ingxenye yokonakaliswa kogu losogwini okwenzeka ngaphansi kwamanzi idlala indima enkulu ekubambiseni le nto ye-lidar, yingakho isinqumo sokusebenzisa i-limbic njengethuluzi le-bathymetric.
UPawel uthe, "Imiphumela yocwaningo isinikeza ukuqonda kokuthi ama-Coastal Cliffs aphendula kanjani ushintsho lwesimo sezulu samanje nesizayo, ikakhulukazi ukukhuphuka kwezinga lolwandle kanye nokwenyuka kwesivunguvungu." "Ukuthuthukisa ucwaningo lwendabuko lwe-geotechnical ngokusebenzisa ubuchwepheshe obusezingeni eliphezulu bokuzwakala okukude, okufana nokusetshenziswa kwezindawo ezibhekene nalolu cwaningo olubhekene nePoland kuphela. ngokuguguleka kwe-Coastal Cliff kanye nokungazinzi. "
Ngokuhlanganisa ukuqoqwa kwemininingwane ye-aarial ne-maritime kusuka ezimotweni ezizimele, leli qembu lososayensi lakwazi ukuthuthukisa ikhwalithi yedatha, ukunemba kweziphetho, futhi nokwanela kweziphetho, futhi nokwanela kwezinyathelo ezithathwa ukunciphisa umonakalo ku-geography kanye nezakhamizi zezindawo ezithintekile.
