Jambulani bwalo langwiro: njira

Zimene amayezera

Chimene chimayezedwa: masewera oyesa kulamulira dzanja; mmene mzere umodzi wotsekedwa wojambulidwa mwaulere umafanana ndi bwalo. Chimene sichimayezedwa: si mayeso a kunjenjemera kapena kayendetsedwe ka thupi a kuchipatala, ndipo kumene munajambulira sikutanthauza chilichonse pa thanzi.

Mmene amachitira

Jambulani kamodzi mozungulira kadontho kapakati pogwiritsa ntchito chala, cholembera kapena mbewa (batani lakumanzere). Pamene mukujambula, mzerewu umasintha mtundu malinga ndi mtunda wa mfundo iliyonse kuchokera pa bwalo lomwe likugwirizana bwino panthawiyo, ndipo chiwerengero cha kuzungulira bwino chimaoneka nthawi yomweyo. Mukakweza cholozera, bwalo lofananitsidwalo limaoneka ndi mzere wodukaduka. Tsambali limasunga mfundozo (CSS px, kulondola kwa 0.1 px) limodzi ndi nthawi zake mu ms, limachepetsa mofanana mpaka mfundo zosapitirira 600 (mfundo yoyamba ndi yomaliza zimasungidwa), ndipo limazitumiza limodzi ndi kukula kwa malo ojambulira.

Miyezo ya makonzedwe

Kuwerengera zotsatira

Pakati pa bwalo amawerengedwa pogwiritsa ntchito njira ya Kåsa ya least squares (kuchepetsa Σ(x² + y² + Dx + Ey + F)²). R = mtunda wapakati wa mfundo kuchokera pakatikati pake. Kupatuka = pafupifupi |r_i − R| / R. Kuizungulira bwino = 100 × (1 − kupatuka), osachepera 0, ndipo kumaperekedwa ngati peresenti yokhala ndi nambala imodzi pambuyo pa kadontho; chiwerengero chokwera chimatanthauza bwalo lozungulira bwino. Njira: motsatira mawotchi kapena motsutsana nawo malinga ndi chizindikiro cha ngodya zonse zikaphatikizidwa. Zina zomwe zimaperekedwanso: utali mu px ndi poyerekezera ndi malo ojambulira, mbali ya bwalo yomwe yajambulidwa, nthawi yojambulira, ndi chiwerengero cha mfundo. Chiwerengero chabwino kwambiri pa njira iliyonse yolowetsamo chimasungidwa mu msakatuli mokha; kuyerekezera kumachitika pakati pa njira yofanana yokha.

Malamulo ovomerezera mayeso ochitidwa

Chojambulacho sichipeza chiwerengero ngati chili ndi mfundo zosakwana 24 kapena bwalo silingafanane ('chachifupi kwambiri'), utali wake uli pansi pa 15% ya mbali yaifupi ('chaching’ono kwambiri'), chadutsa 430° ('chazungulira kwambiri'), chili pansi pa 320° kapena mpata wotsekera wadutsa 0.35 R ('sichinatsekeke'), kapena chatenga nthawi yoposa 30 s ('chachedwa kwambiri'). Nthawi za mfundo siziyenera kubwerera m’mbuyo, ndipo mbali iliyonse ya malo ojambulira iyenera kukhala pakati pa 50–10,000 px.

Kusiyana ndi ntchito yakale yoyambirira

Palibe njira imodzi yovomerezeka ya m’ma labotale. Maphunziro a kayendedwe ka kujambula (mwachitsanzo Lacquaniti et al., 1983) amasunga njira zimene cholembera cha pa bolodi la digito chadutsamo ndipo amasanthula liwiro ndi kupindika; ntchito za kuchipatala monga kujambula kozungulira kwa Archimedes zimagwiritsa ntchito maonekedwe ndi ziwerengero zosiyana. Apa bwalo limodzi limayesedwa pa maonekedwe ake okha.

Zimene mayesowa sangathe kuyeza

Mfundo zimafika mogwirizana ndi liwiro limene chipangizo chimazitenga, choncho mbali za mzere zojambulidwa pang’onopang’ono zimapereka mfundo zambiri pa chiwerengero chapakati. Zimene mukuona pamene mukujambula zimakulolani kukonza mzerewo. Kukula kwa sikirini, chala kubisa mbali ya sikirini, ndiponso kusiyana kwa mbewa ndi chala zimasintha ziwerengero. Kuyeserera kumakweza ziwerengero. Si mayeso a zachipatala.

Zinenero ndi mmene zawunikidwira

Zithunzi kapena zinthu zoyesedwa sizidalira chinenero; malangizo akupezeka m’zinenero zonse za tsambali.
