accelerometer

Ke ka lebaka leo li-accelerometers e leng metsoalle e metle ea li-gyroscopes: hobane li khona ho bona litšupiso tse ntle haholo tsa "tlase" (bonyane, ha li le boemong ba matla a khoheli a lefats'e).

Hantle, ho bua ka kakaretso. Ho tloha motsotsong o mong ho ea ho o mong, e fumana matla a khoheli, ho potlakisa lebelo, matla a centrifugal a hlahisoang ke ho potoloha, ho sisinyeha, lerata le, ha e le hantle, liphoso tsa kutlo.

Ka hona, ho sa tsotellehe sekhahla se phahameng sa lisampole le ho nepahala ho hotle ha li-sensor tsa MEMS (hangata li ntle joaloka li-gyroscopes), data ea accelerometer e ntse e le e 'ngoe ea lintlha tse lerata le tse sa tšepahaleng. E amohetse "lipontšo" tse 'maloa tse tlamehang ho se utloisisehe. Empa ke maikutlo a mats'oao ana a fapaneng a etsang hore e be bokahohleng - e khona ho utloa tsohle.

Ho na le mehato e 'meli ea ho kopanya ea ho potlakisa ho tloha sebakeng seo re hlileng re batlang ho se tseba, kahoo re tlameha ho akaretsa li-deltas tse ngata le mela ea liphoso, ho tloha ho potlakiso e lekantsoeng ho ea ho lebelo le lekantsoeng, ebe re tlameha ho e etsa hape ho fumana tekanyo e lekantsoeng. boemo. Liphoso li ntse li eketseha.

Ke ka lebaka lena GPS e leng motsoalle oa accelerometer: hobane e tla "zero" phoso ea boemo bo ntseng bo eketseha nako le nako, joalo ka ha accelerometer e fokotsa phoso ea azimuth ea gyroscope.

Sesupa-tsela se setle ha sea lokela ho hlokomolohuoa. Leha ho le joalo, joalo ka accelerometer, hangata e sebelisoa e le mokhoa oa ho laola nako e telele ea gyro drift. Ho tseba hore na ho ea holimo ke tsela efe ho molemo ho feta ho tseba hore na ke tsela efe e ka leboea ea makenete—empa ka tsena tse peli, re ka tseba boemo ba rōna bo botle e le kannete lefatšeng.

Hangata li kopantsoe le ba amohelang GPS, hobane ba boetse ba loantšana le bofokoli bo boholo ba ba bang, empa ba tšoana hantle le likarolo tse ling. E 'ngoe e fana ka maemo a mabe haholo, 'me e' ngoe e fana ka tsela e majabajaba.
