Lefapheng le ntseng le hōla ka potlako la likoloi tse sa tsamaisoang ke lifofane (UAVs), li-inertial measurement units (IMUs) li hlahella e le karolo ea bohlokoa bakeng sa ho ntlafatsa ts'ebetso ea lifofane le ho nepahala ha ho tsamaea. Ha tlhokahalo ea li-drones e ntse e eketseha liindastering ho tloha ho tsa temo ho ea ho leihlo, ho kopanngoa ha theknoloji e tsoetseng pele ea IMU ho ntse ho e-ba bohlokoa le ho feta. Sengoliloeng sena se shebana le karolo ea bohlokoa ea li-IMU ho li-drones, ho bonts'a hore na li kenya letsoho joang ho fofa ho tsitsitseng, ho tsamaea ka tsela e nepahetseng le ho qoba litšitiso.
Bohareng ba drone e 'ngoe le e' ngoe e sebetsang hantle ke IMU, kopano e rarahaneng ea sensor e lekanyang ka hloko le ho tlaleha motsamao oa mahlakore a mararo a drone. Ka ho kopanya li-gyroscopes, accelerometers le magnetometers, IMU e fana ka lintlha tsa bohlokoa mabapi le maikutlo a drone, ho potlakisa le lebelo la angular. Tlhahisoleseding ena hase feela tlhahisoleseding e tlatsetsang; ho bohlokoa ho netefatsa hore sefofane se tsitsitse le ho tsamaea hantle. IMU e sebetsa e le boko ba drone, e sebetsana le data ea nako ea sebele le ho tsebisa tsamaiso ea tsamaiso ea lifofane, ho lumella ho sebetsa ka mokhoa o se nang moeli libakeng tse sa tšoaneng.
E 'ngoe ea likarolo tse hlahelletseng tsa IMU ke bokhoni ba eona ba ho fana ka tlhaiso-leseling ea nako ea nnete. IMU e etsa bonnete ba hore drone e boloka tsela e tsitsitseng ea sefofaneng ka ho lekanya lebelo la molumo, angle angle le eaw angle ea drone. Bokhoni bona bo bohlokoa haholo maemong a phephetsang joalo ka meea e matla kapa moferefere, moo le ho kheloha ho honyenyane ho ka lebisang liphosong tse tebileng tsa ho sesa. Ka litekanyo tse nepahetseng tsa IMU, basebelisi ba drone ba ka ba le ts'epo ea hore li-drones tsa bona li tla sebetsa ka ts'epo le maemong a boima haholo.
Ho feta moo, IMU e boetse e bapala karolo ea bohlokoa ho thusa ho tsamaea. Ha e kopantsoe le lisensara tse ling tse kang GPS, lintlha tse fanoeng ke IMU li ntlafatsa bokhoni ba drone ho tseba hore na e hokae le hore na e hokae ka ho nepahala ho holimo haholo. Tšebelisano pakeng tsa IMU le theknoloji ea GPS e thusa ho tsamaea ka tsela e nepahetseng, e lumellang li-drones ho phethahatsa litsela tse rarahaneng tsa sefofane le mesebetsi. Ebang ke ho etsa 'mapa oa masimo a maholo kapa ho hlahloba lifofane, li-IMU li netefatsa hore li-drones li lula tseleng le ho fana ka liphetho tse finyellang kapa tse fetang tebello.
Ntle le ho tsamaea, IMU e thusa ho qoba litšitiso le ho boloka sefofane se tsitsitse. Lintlha tse hlahisoang ke IMU li kenngoa ho algorithm ea taolo ea sefofane, e lumellang drone ho lemoha le ho qoba litšitiso ka nako ea sebele. Bokhoni bona bo bohlokoa bakeng sa lits'ebetso tse joalo ka lits'ebeletso tsa phano, moo lifofane li tlamehang ho tsamaea libakeng tsa litoropo tse nang le meaho, lifate le likotsi tse ling tse ka bang teng. Ka ho sebelisa lintlha tse tsoang ho IMU, drone e ka etsa liqeto tse arohaneng ho fetola tsela ea eona ea sefofane, ho netefatsa polokeho le katleho.
Li-sensor tse tsoetseng pele ka har'a IMU, ho kenyelletsa le li-sensor tsa MEMS le li-gyroscopes tse tharo-axis, ke senotlolo sa ho fihlela bokhoni bona bo tsotehang. Li-sensor tsa MEMS li sebelisa meaho e menyane ea mochini ho lekanya lebelo le lebelo la angular ka nepo, ha li-gyroscopes tse tharo tsa axis li hapa motsamao oa potoloho ea drone ka litekanyo tse tharo. Ka kopanelo, likarolo tsena li theha sistimi e matla e lumellang drone ho sebetsa ka nepo le ho ts'epahala ho ke keng ha bapisoa.
Ka bokhutšoanyane, ts'ebeliso eaIMUthekenoloji ea li-drones e tla fetola melao ea indasteri. IMU e ntlafatsa ts'ebetso ea kakaretso ea drone ka ho fana ka lintlha tse hlokahalang bakeng sa sefofane se tsitsitseng, ho tsamaea ka mokhoa o nepahetseng le ho qoba litšitiso tse sebetsang. Ha 'maraka oa drone o ntse o hola, ho tsetela ho theknoloji e tsoetseng pele ea IMU ha ho pelaelo hore e tla ba ntlha ea bohlokoa ho fihlelleng bokhabane ba ts'ebetso le ho fihlela litlhoko tse fapaneng tsa liindasteri tse fapaneng. Amohela bokamoso ba ho fofa ka li-drones tse nang le IMU 'me u bone phapang ea ho nepahala le botsitso tse tlisoang ke ts'ebetso ea sefofane.
