Chabwino, ili ndi funso lomveka koma lopanda yankho losavuta.Pali zinthu zambiri zomwe zingakhudze zotsatira zake, monga kuchepetsedwa kwa nyengo zosiyanasiyana, kukhudzika kwa chowunikira chotenthetsera, ma algorithm oyerekeza, phokoso lakufa komanso phokoso lakumbuyo, komanso kusiyana kwa kutentha kwapakati.Mwachitsanzo, chiboliboli cha ndudu chimatha kuwona bwino kwambiri kuposa masamba amtengo womwe ali pamtunda womwewo ngakhale atakhala waung'ono kwambiri, chifukwa cha kusiyana kwa kutentha komwe kumatsata.
Mtunda wodziwikiratu ndi chifukwa cha kuphatikiza kwa zinthu zomwe zimakhazikika komanso zolinga.Zimakhudzana ndi malingaliro amunthu wowonera, zochitika ndi zina.Kuti tiyankhe "kodi kamera yotentha ingawone bwanji", tiyenera kupeza tanthauzo lake poyamba.Mwachitsanzo, kuti azindikire chandamale, pomwe A akuganiza kuti atha kuchiona bwino, B sangatero.Chifukwa chake, payenera kukhala mulingo wowunikira womwe ndi wogwirizana.
Zolinga za Johnson
Johnson anayerekezera vuto lozindikira maso ndi mawiri awiri a mzere malinga ndi kuyesako.Mizere iwiri ndi mtunda wotsitsidwa kupyola kuwala kofananira ndi mizere yakuda pa malire a kuwona bwino kwa wowonera.Mizere iwiri ndi yofanana ndi ma pixel awiri.Kafukufuku wambiri wasonyeza kuti ndi zotheka kudziwa chandamale kuzindikira chandamale dongosolo infuraredi matenthedwe imager pogwiritsa ntchito mizere awiriawiri popanda kuganizira chikhalidwe cha chandamale ndi zolakwika zithunzi.
Chithunzi cha chandamale chilichonse mundege yapakatikati chimakhala ndi ma pixel angapo, omwe amatha kuwerengedwa kuchokera ku kukula, mtunda wapakati pa chandamale ndi chojambula chotenthetsera, komanso malo owonera nthawi yomweyo (IFOV).Chiŵerengero cha kukula kwa chandamale (d) kwa mtunda (L) kumatchedwa ngodya ya aperture.Ikhoza kugawidwa ndi IFOV kuti mupeze chiwerengero cha ma pixel omwe ali ndi chithunzi, ndiye n = (D / L) / IFOV = (DF) / (LD).Zitha kuwoneka kuti kukula kwa utali wokhazikika, m'pamenenso chithunzi chandamale chimakhala chokhazikika.Malinga ndi muyezo wa Johnson, mtunda wodziwikiratu uli patali.Kumbali ina, kukula kwa utali wokhazikika, kumachepetsa kolowera kumunda, ndipo mtengo wake umakhala wokwera.
Titha kuwerengera kutalika kwa chithunzi chotenthetsera chomwe chimatha kuwona kutengera malingaliro ochepa malinga ndi Zolinga za Johnson ndi:
Kuzindikira - chinthu chilipo: 2 +1/-0.5 pixels
Kuzindikira - mtundu wa chinthu ukhoza kuzindikira, munthu motsutsana ndi galimoto: 8 + 1.6 / -0.4 pixels
Chizindikiritso - chinthu chenichenicho chikhoza kuzindikiridwa, mkazi motsutsana ndi mwamuna, galimoto yeniyeni: 12.8 +3.2 / -2.8 pixels
Miyezo iyi imapereka mwayi wa 50% wa wowonera kusankha chinthu pamlingo wotchulidwa.
