Maxay yihiin baaxadda sawirka?

Ka hor inta aadan bilaabin eegaya baaxadda caadiga ah ee sawirka, waxaa la fahamsan yahay waa in ay tahay fikrad la siiyey. Sidaas darteed, qiimaha noocan oo kale ah guud ahaan waa cabirku yahay laba dhinac toosan. Si kastaba ha ahaatee, inta badan loo yaqaan fasiraad ah qeexitaanka tan oo kale ah, sida ratio of size ee sawirka si size ee shayga dhabta ah. Sidaas awgeed, waxaan ku habboonayn in la malaysan karo in muddada ku xusan ayaa si weyn loo isticmaalaa in cartography, sahan, iyo dabcan, design.

Maxay tani lagama maarmaan tahay?

Sida hore loo sheegay, shayga dhabta ah ayaa laga yaabaa inay wax ku filan size waaweyn iyo aad u yar noqon. Si kastaba ha ahaatee, qof aan mirashada kartaa wax nolosha-size, sida bandhigay on warqad, qorshaha dhismaha u baahan doonaa size shiraac weyn, iyo, ka bacdi, si ay u cilinta waxyaabaha yaryar (sida in hab saacba) u baahan tahay shahaado sare oo faahfaahsan. Sidaas darteed, dadka ku habboon si ay u matalaan waxyaalaha lagama maarmaanka ah, taas oo in tiro cayiman oo jeer hoos u dhacay (ama kordhay), waayo, Hufnaan iyo kuwa lagu magacaabo "akhriska" xidhiidh. Currently, waxaa jira heerarka gaar ah, tusaale ahaan, GOST "qiyaasta sawirka" oo qeexaya shuruudaha oo dhan inay foomka iyo buuxinta ee images kala.

waxyaabaha waaweyn

Sidii hore, waayo bandhigay ee dhismayaasha iyo waxyaabaha kale ee waaweyn ku xusan waxay u baahan yihiin in la isticmaalo qiyaasta sawirka ee loo yaqaan hoos. Waxay yihiin caadiga ah, taas oo macnaheedu yahay in sampling random ma ku haboon. Inta badan la kulantay qiyamka soo socda: 1: 2; 2.5; 4; 5; 10; 15; 20; 25; 40; 50; 75; 100; 200; 400; 500; 800; 1000. ha na arag waxa uu yahay rikoorka noocan ah. Sayidka, dhabta ah (si kale loo dhigo, dabiiciga ah) aragti shay waxaa lagu qeexay qaab Ereyada 1: 1. Sidaas awgeed, la hoos sawiro qiyaasta ugu horeysay ku tilmaami size asalka ah (1) raacay by tiro ka mid ah taas oo muujinaysaa inta jeer ay barbaro galeen waa la dhimay qaraabo in dhinacyada dhabta ah. In dhismaha, marka lagu daro diiwaanka kor ku xusan Heerka, tilmaamo sidoo kale waxaa loo isticmaali karaa 1: 2000; 5000; 10000; 20000; 25000; 50,000.

qaybo yar yar

Haddii ay sidaa tahay, haddii tirada loo baahan yahay inaan ka dhaansado waxyaabaha yaryar, qiyaasta soo jireenka ah ee kordhay sawiro ayaa loo isticmaalaa. Xaaladdan oo kale, waxaa jira sida kala duwan oo qiimaha, laakiin heer xusan qiimaha inta badan loo isticmaalaa. Sidaas darteed, tirada caadiga ah waa sida soo socota: 2; 2.5; 4; 5; 10; 20; 40; 50; 100: 1. Sharax sumadaha la mid ah la akhriyo sida soo socota: ugu horeysay tiro tilmaamaya inta jeer ee image ah in sawirka u korodho sida shayga asalka ah marka la barbar dhigo. The lambar labaad ka dib markii colon muujiso (aka - dabiici ah ama dhab ah) dhabta ah size of shayga (qaataa inay tahay 1).

gunaanad

Maqaalkani waxa uu baaro iskeelka oo ka mid ah sawiro iyo heerka sareysa. Sidoo kale waa in la ogaadaa in u gaar ah qorshaha, mashaariicda iyo qiimaha zoom ku qeexan sanduuq gaar ah ee ku yiilleen, haddii kale loo yaqaan shaabad ah.
