Qeexitaanka Muraayadda Convex
Nooc ka mid ah muraayadaha loo isticmaalo nolol maalmeedka waa muraayad qaloocan. Muraayadda qaloocan waa muraayad leh qaab qaloocan, halkaas oo dusha sare ee muraayadda ee ka tarjumaysa qaloocyada iftiinka ay hore u socoto.
Isticmaal
Haddii aad waligaa aragtay muraayad gadaal ah oo mooto ama gaari ah, waxaad u badan tahay inaad taqaanid isticmaalka maalinlaha ah ee muraayadaha wareegsan. Waxaa loo isticmaalaa muraayadaha gadaal ah sababtoo ah sawirka ay soo saaraan wuu yar yahay, taasoo u oggolaanaysa aragti ballaaran. Marka laga soo tago cabbirka sawirka yar, dhammaan sawirrada la soo saaray waa kuwo casri ah ama kuwo male-awaal ah. Fadlan baro mawduuca. sawir muraayad qaloocan si aad u caddeyso fahamkaaga.
Barta Focus
Haddii dusha sare ee muraayadda iftiinka ka tarjumaysa ay la kulanto shay aad u fog, sida qorraxda, markaa iftiinka iftiinka ee qorraxdu soo saarto wuxuu la mid noqon doonaa dhidibka ugu weyn ee muraayadda, sida ku cad sawirka hoose. dhidibka ugu weyn waa xariiq male-awaal ah oo ku toosan bartamaha dusha muraayadda.
Marka muraayadda la dul saaro, iftiin kasta ama iftiin kasta wuu u hoggaansamaa sharciga iftiiminta iftiinkaDhammaan fallaaraha milicsanaya waxay u muuqdaan inay ka yimaadaan barta dhexe ee muraayadda qaloocan (F). Si kale haddii loo dhigo, barta dhexe waa barta sawirka ee shay aad uga fog dusha sare ee muraayadda sawirkanina waa mid casri ah.
Dhererka Fog
Dhererka focal (f) waa masaafada u dhaxaysa barta focal (F) iyo dusha muraayadda. Barta C waa bartamaha qalooca muraayadda. Dhererka focal ee muraayadda waa f (dhererka focal = f = FQ) iyo gacanka qalooca muraayadda waa r (raadka qalooca = r = CQ = CP).
Falaadhaha dhacdada ayaa muraayadda ku dhaca P ka dibna waxaa ka muuqda muraayadda, halkaas oo fallaadhaha milicsanaya ay u muuqdaan inay ka yimaadeen barta dhexe ee F. Sadarka dhibcaha leh ee CP waa xariiqda caadiga ah. Falaadhaha dhacdada iyo fallaadhaha milicsanaya waxay u hoggaansamaan sharciga milicsiga iftiinka halkaas oo xagasha dhacdooyinka (θ) ay la mid tahay xagasha milicsiga (θ) xagashanina ay la mid tahay xagasha saddexagalka PCQ (θ). Xagasha saddexagalka PCQ waxay la mid tahay xagasha saddexagalka CPF sidaas darteed saddexagalka PFC waa saddexagalka siman. Maadaama saddexagalka PFC uu yahay saddexagalka siman markaa dhererka PF wuxuu la mid yahay dhererka CF. Marka la qiyaaso in ballaca muraayaddu uu ka yar yahay radius-ka qalooca muraayadda qalooca sidaas darteed dhererka PF waxaa loo arkaa inuu la mid yahay dhererka FQ. Sababtoo ah CF = PF iyo PF = FQ markaas CQ = 2 CF = 2 FQ. CQ = r = radius-ka qalooca muraayadda iyo FQ = f = dhererka focal ee muraayadda. Sidaas darteed waxaa lagu soo gabagabeyn karaa in radius-ka qalooca muraayadda (r) = 2 x dhererka focal (f) ee muraayadda. Xisaab ahaan:
r = 2 f ama f = r / 2
Hooska
Muraayadaha isku laaban waxay samayn karaan sawirro dhab ah iyo kuwo dalwad ah, halka muraayadaha isku laaban ay samayn karaan oo keliya sawirro dalwad ah. Samaynta sawirka shay iyadoo la adeegsanayo muraayad isku laaban ayaa si faahfaahsan loogu sharraxay mawduuca. sawir muraayad qaloocan.
Hooska Maya
Marka iftiinka u soo socda dusha muraayadda la milicsado, jihada iftiinka ka soo muuqda waxay u muuqataa inay ka timid barta dhexe ee muraayadda iyo bartamaha qalooca muraayadda. Sababtoo ah iftiinku dhab ahaantii ma dhaafo muraayadda gadaasheed, sawirka la sameeyay waa hooska dalwaddu ama khiyaanoHaddii aad shaashadda dhigto meel uu ku yaal sawirka casriga ah, hoos kama muuqan doono shaashadda.
