A umugqa we-scan lensiyilensi ekhethekile esetshenziswa kakhulu kumakhamera we-Scan. Kwenza ukuskena okusheshayo okufana nokucabanga okulinganiselwe. Ihlukile kumalensi wekhamera yendabuko futhi ivame ukusetshenziswa ensimini yezimboni.
Uyini umgomo osebenzayo wokuskena umugqalens?
Umgomo osebenzayo we-Line Scan Lens usekelwe ubuchwepheshe be-Line Scan. Lapho usebenza, umugqa we-lens uskena umugqa wesampula wesampula ngomugqa bese uqoqa imininingwane yokukhanya yomugqa ngamunye wamaphikseli ukusiza umugqa wesampula lonke esikhundleni sawo wonke.
Ngokukhethekile, umgomo osebenzayo welensi yokuskena yomugqa uqukethe izinyathelo eziningana:
Ukucabanga okubonakalayo:Isiginali yokukhanya yesampula okufanele iskenwe ithathwe yizinto ezithandekayo ze-Line-by-line photossetive ezintweni ezithwebule umugqa welensi bese iguqulwa ibe yizimpawu zikagesi.
Ukuskena kwe-Line-by-line:I-Iment ye-Line-by-line eye yento eskena ukusuka phezulu kuya phansi kwesampula ngejubane elithile, ukuguqula imininingwane yokukhanya yomugqa ngamunye ibe yisiginali kagesi.
Ukucutshungulwa kwesiginali:Ngemuva kokucubungula, isiginali kagesi iguqulwa ibe yisiginali yedijithali yokwenza isithombe.
Ukuthunga kwesithombe:Stitch ndawonye amasiginali edijithali emugqeni ngamunye ukuze ekugcineni akha isithombe salo lonke isampula.
Umgomo osebenzayo weLine Scan Lens
Yimaphi amapharamitha okufanele anakekele amalensi wokuskena?
Amapharamitha weumugqa we-scan lenszihlobene kakhulu nezidingo ezahlukahlukene nezimo zohlelo lokusebenza. Amapharamitha alandelayo adinga ukugxila ku:
Isixazululo
Ukulungiswa kweLein Scan Lens kuvame ukuba yi-metric eyinhloko yokukhathazeka. Ukuphakama kwesinqumo, okuphezulu kwesithombe, okuhlobene nenani lamaphikseli endaweni yokucabanga kanye nosayizi wento ethile.
Umphetho
Ubukhulu bokusebenzisa i-aperture lilawula inani lokukhanya elingena ku-lens, elithinta ukukhanya kwesithombe selensi kanye nesikhathi sokuvezwa kwefilimu. Ukuhlobisa okukhulu kungathuthukisa ikhwalithi yesithombe lapho isetshenziswa ezimweni eziphansi zokukhanya, kepha kunganciphisa uhla lokujula.
Ibanga lokugxila
Ubanga lokugxila kubhekisele ebangeni le-lens elingadubula. Ngokuvamile, ababanzi abangcono, futhi basebenzise izindlela kungadubula izinto eziningi zobude obuhlukile bokugxila.
Ukuphakama kwesithombe
Ukuphakama kwesithombe kubhekisele kubude bendawo ye-lens imaging endaweni yokuskena. Ukuphakama kwesithombe esikhudlwana kudinga ijubane lokuskena ngokushesha, okuzobuye kuholele isivinini sokucabanga esiphakeme kanye nesilinganiso sokudlulisa idatha esiphakeme.
Gxila kukhwalithi yesithombe
Iikhwalithi yemali
Ikhwalithi yokulingisa ingalinganiswa ngamapharamitha anjengeso isixazululo samuva, isilinganiso se-Signal-to-Noise, kanye nombala we-saturation. Imvamisa, ukulungiswa okuphezulu okuphezulu, isilinganiso se-Signal-to-Noise, kanye nombala we-saturation kusho ikhwalithi yesithombe esiphakeme.
Usayizi welensi nesisindo
Usayizi nesisindo kungathinta ukusetshenziswa kweumugqa we-scan lenskwezinye izinhlelo. Ngakho-ke, ubukhulu nesisindo selensi nakho kudinga ukubhekwa ngokuya ngezimo ezihlukile zohlelo.
Imicabango yokugcina:
Uma unesifiso sokuthenga izinhlobo ezahlukahlukene zamalensi zokubhekwa, ukuskena, ama-drones, ekhaya elihlakaniphile, noma okunye ukusetshenziswa, sinakho okudingayo. Xhumana nathi namuhla ukuze ufunde kabanzi ngama-lens ethu nezinye izesekeli.
