一,Mhando dzeMagirazi eKamera ekuchengetedza:
Magirazi emakamera ekuchengetedza anouya mumhando dzakasiyana, imwe neimwe yakagadzirirwa kuenderana nezvinodiwa zvekutarisa. Kunzwisisa mhando dzemagirazi aripo kunogona kukubatsira kusarudza yakakodzera kamera yako yekuchengetedza. Heano marudzi akajairika emagirazi emakamera ekuchengetedza:
1,Lenzi Yakagadzika: Lenzi yakagadzika ine urefu humwe chete hwekutarisa uye nzvimbo yekuona, izvo zvisingagone kugadziriswa. Isarudzo inodhura zvishoma yakakodzera kutarisa nzvimbo chaiyo pasina chikonzero chekugadzirisa kakawanda. Lenzi dzakagadzika dzinowanikwa muhurefu hwakasiyana hwekutarisa, zvichikubvumidza kusarudza nzvimbo yaunoda yekuona.
2,Lenzi yeVarifocal: Lenzi ine ruvara rwevarifocal inopa urefu hwefocal hunogadziriswa, zvichikubvumidza kuti uchinje nzvimbo yekuona nemaoko. Inopa rusununguko mukugadzirisa level ye zoom uye yakakodzera mamiriro ezvinhu apo nzvimbo yekutarisa inogona kuchinja kana kuda mazinga akasiyana eruzivo. Lenzi dzine ruvara rwevarifocal dzinowanzo shandiswa mumamiriro ezvinhu apo kudikanwa kwekushanduka-shanduka, senge kutarisa kwekunze.
3,Lenzi yeZoom:Lenzi ye zoom inopa mukana wekugadzirisa urefu hwe focal uye nzvimbo yekuona iri kure. Inobvumira optical zoom uye digital zoom. Optical zoom inochengetedza hunhu hwemufananidzo nekugadzirisa zvinhu zve lenzi, nepo digital zoom ichikudza mufananidzo nedhijitari, zvichikonzera kurasikirwa nehunhu hwemufananidzo. Ma lenzi e zoom anowanzo shandiswa mumapurogiramu uko kutarisa kure uye kugona kutora ruzivo rwakanaka kwakakosha, senge munzvimbo huru dzemukati kana dzekunze.
4,Lenzi Yakafara: Lenzi ine angle yakafara ine urefu hupfupi hwe focal, zvichikonzera nzvimbo yakakura yekuona. Yakakodzera kutarisa nzvimbo dzakakura kana nzvimbo dzakashama uko kutora maonero akafara kwakakosha. Lenzi dzine angle yakafara dzinowanzo shandiswa mumamiriro ekutarisa akadai senzvimbo dzekupaka mota, mawarehouse, kana kutarisa miganhu yekunze.
5,Lenzi yeTelephoto: Lenzi ye telephoto ine urefu hwakareba hwe focal, ichipa nzvimbo yakamanikana yekuona uye kukura kukuru. Yakanakira kutarisa kure kana mamiriro ezvinhu apo kutora ruzivo rwakati kure kwakakosha. Lenzi dze telephoto dzinowanzo shandiswa pakushandisa senge rezinesi rekuona, kuzivikanwa kwechiso, kana kutarisa nzvimbo dzakakosha uri kure.
6,Lenzi yePinhole:Lenzi ine gomba remusana igirazi rakasiyana-siyana diki uye rakavanzwa. Rakagadzirirwa kuvanzwa mukati mezvinhu kana pamusoro, zvichibvumira kutariswa kwakavanzika. Lenzi dzine gomba remusana dzinowanzo shandiswa mumamiriro ezvinhu apo kamera inoda kuvanzwa kana kuvanzwa, senge mumaATM, maburi emusuwo, kana mabasa ekutarisa pachivande.
二,Maitiro Ekusarudza Lenzi Yakanakisisa Yekamera Yako Yekuchengetedza？
Kusarudza lenzi yakanakira kamera yako yekuchengetedza idanho rakakosha pakuona kuti inoshanda zvakanaka uye kutora mavhidhiyo emhando yepamusoro. Heano mamwe matipi ekufunga nezvawo pakusarudza lenzi:
Rudzi rweKamera:Sarudza rudzi rwekamera yekuchengetedza yauinayo kana kuti yauri kuronga kutenga. Mhando dzakasiyana dzemakamera, dzakadai sebullet, dome, kana PTZ (pan-tilt-zoom), dzingada mhando kana saizi dzakatarwa dzemalenzi.
Kureba kweFocal: Kureba kwefocal kunosarudza nzvimbo yekuona uye mwero we zoom. Inoyerwa nemamirimita (mm). Sarudza urefu hwefocal hunoenderana nezvaunoda. Heano mamwe masarudzo akajairika:
Lenzi Yakafara(2.8mm kusvika 8mm): Inopa nzvimbo yakakura yekuona, yakakodzera kufukidza nzvimbo dzakakura kana kutarisa nzvimbo dzakafara.
Lenzi Yakajairika (8mm kusvika 12mm): Inopa maonero akaenzana akakodzera kushandiswa kwekutarisa kwakajairika.
Lenzi yeTelephoto (12mm zvichikwira): Inopa nzvimbo yakamanikana yekuona asi inopa kugona kukuru kwekutarisa kure kana kuti kuona zviri pedyo.
Munda weKuona (FOV): Funga nezvenzvimbo yaunoda kutarisa uye huwandu hwezvinhu zvinodiwa. Nzvimbo yakakura yekuona inobatsira munzvimbo dzakakura dzakashama, nepo FOV yakamanikana iri nani kune nzvimbo dzakatarwa dzinoda kunyatsoongororwa.
Aperture: Aperture ndiyo inosarudza kugona kwelenzi kuunganidza chiedza. Inomiririrwa nenhamba ye f (semuenzaniso, f/1.4, f/2.8). Nhamba ye f yakaderera inoratidza aperture yakafara, zvichiita kuti chiedza chakawanda chipinde mulenzi. Aperture yakafara inobatsira mumamiriro ekunze asina chiedza chakawanda kana kutora mifananidzo yakajeka murima.
Kuenderana kweSensor yeMufananidzo: Iva nechokwadi chekuti lenzi inoenderana nehukuru hwesensa yemufananidzo wekamera yako. Saizi dzesensa yemufananidzo dzinosanganisira 1/3″, 1/2.7″, uye 1/2.5″. Kushandisa lenzi yakagadzirirwa saizi chaiyo yesensa kunobatsira kuchengetedza kunaka kwemufananidzo uye kudzivirira kusvibiswa kana kukanganiswa kwemufananidzo.
Lenzi yeMount: Tarisa rudzi rwekugadzika lenzi runodiwa pakhamera yako. Mhando dzekuisa dzakajairika dzinosanganisira CS mount neC mount. Iva nechokwadi chekuti lenzi yaunosarudza inoenderana nerudzi rwekuisa lenzi yekamera.
Lenzi yeVarifocal vs. Fixed:Magirazi eVarifocal anokutendera kuti ugadzirise urefu hwefocal nemaoko, zvichikupa mukana wekuchinja nzvimbo yekuona sezvinodiwa. Magirazi akasimba ane urefu hwefocal hwakatarwa uye anopa nzvimbo yekuona yakatarwa. Sarudza mhando yakakodzera zvichienderana nezvinodiwa zvako zvekutarisa.
Bhajeti:Funga nezvebhajeti yako pakusarudza lenzi. Malenzi emhando yepamusoro ane zvinhu zvepamusoro anogona kudhura asi anogona kupa mufananidzo wakanaka uye kugara kwenguva refu.
Mugadziri uye Ongororo:Tsvaga vagadziri vane mukurumbira vanonyanya kugadzira magirazi emakamera ekuchengetedza. Verenga wongororo dzevatengi uye tsvaga mazano ekuona kuti unosarudza chigadzirwa chakavimbika uye chine mukurumbira.
三,Kusarudza Lenzi Yemukati Neyekunze: Musiyano Chii?
Pakusarudza lenzi yekutarisa mukati kana panze, pane misiyano mishoma yekufunga nezvayo nekuda kwehunhu hwakasiyana hwenzvimbo idzi. Hezvino zvaunofanira kuziva:
Mamiriro emwenje:Nzvimbo dzekunze dzinowanzova nemamiriro akasiyana-siyana echiedza, kusanganisira chiedza chezuva chakajeka, mimvuri, uye mamiriro ekunze asina chiedza chakawanda panguva yehusiku. Nzvimbo dzemukati, kune rumwe rutivi, dzinowanzova nemamiriro ekunze ane chiedza chakawanda chine chiedza chinogara chichijeka. Nokudaro, kusarudza lenzi kunofanirwa kufunga nezvematambudziko chaiwo emwenje enzvimbo yega yega.
Kunze:Sarudza lenzi ine aperture yakafara (f-number yakaderera) kuti uwane chiedza chakawanda mumamiriro ekunze asina chiedza chakawanda. Izvi zvinoita kuti mufananidzo uoneke zviri nani uye uve nani panguva yemanheru, mambakwedza, kana husiku. Pamusoro pezvo, lenzi dzine hunyanzvi hwakanaka hwekushandura mifananidzo dzinogona kubata musiyano uripo pakati pezuva rakajeka nenzvimbo dzine mumvuri zvinobudirira.
Mukati: Sezvo nzvimbo dzemukati dzichiwanzova nechiedza chakafanana, malenzi ane maburi ari pakati nepakati anogona kukwana. Lenzi ine nhamba ye f yakakwira zvishoma inogona kupa mufananidzo wakanaka munzvimbo dzemukati pasina chikonzero chekukwanisa kuvhura kwakafara.
Munda weMaonero:Nzvimbo inodiwa yekuona inogona kusiyana zvichienderana nehukuru uye marongerwo enzvimbo yekutarisa.
Kunze: Nzvimbo dzekunze dzinowanzoda nzvimbo yakakura yekuona kuti nzvimbo dzakakura dzionekwe zvakanaka. Magirazi ane makona akafara anowanzo shandiswa kubata nzvimbo yakakura, kunyanya munzvimbo dzakashama dzakadai senzvimbo dzekupaka mota kana kunze kwezvivako.
Mukati: Nzvimbo yekutarisa yekutarisa mukati inogona kusiyana zvichienderana nenzvimbo chaiyo iri kutariswa. Mune zvimwe zviitiko, lenzi ine angle yakafara ingakodzera kufukidza imba yakakura kana koridho. Zvisinei, munzvimbo dzakamanikana kana panodiwa kutarisa zvakadzama, lenzi ine nzvimbo yakamanikana yekuona kana kugona kugadzirisa urefu hwefocal (varifocal lens) ingasarudzwa.
Kuramba Kwemamiriro Ekunze: Makamera nemalenzi ekutarisa panze anofanirwa kugadzirwa kuti agone kutsungirira mamiriro ekunze akaoma, akadai semvura, sinou, guruva, kana tembiricha yakanyanya. Zvakakosha kusarudza malenzi akagadzirirwa kushandiswa panze, ayo anowanzo uya nezvinhu zvinodzivirira mamiriro ekunze zvakaita semavharo akavharwa kuti adzivirire kubva kuhunyoro nemarara.
Kuramba Kuparadza:Munzvimbo dziri kunze, pane njodzi yakakura yekukuvadzwa kana kukanganiswa. Funga nezvemalenzi ane zvinhu zvinodzivirira zvakaita semakesi kana madome anodzivirira kukuvadzwa uye ona kuti mashandiro ekamera uye kunaka kwemufananidzo hazvina kukanganiswa.
Kuenderana kweIR:Kana sisitimu yako yekutarisa iine infrared (IR) kuvheneka kwekuona husiku, iva nechokwadi chekuti lenzi yacho inoenderana nechiedza cheIR. Mamwe malenzi anogona kunge aine IR-cut filter kuti awedzere kunaka kwemufananidzo masikati uku achibvumira IR kuvheneka zvakanaka husiku.
