Makamera emumaindasitiri ndiwo akakosha muhurongwa hwekuona kwemuchina. Basa rawo guru nderekushandura masaini emagetsi kuita masaini emagetsi akarongwa emakamera madiki emumaindasitiri ane hunyanzvi hwepamusoro.
Mumasystem ekuona kwemuchina, lenzi yekamera yemuindasitiri yakaenzana neziso remunhu, uye basa rayo guru nderekutarisa mufananidzo wechiedza uri pamusoro pechinhu chinonzwa chiedza chemufananidzo (kamera yeindasitiri).
Ruzivo rwese rwemifananidzo rwunogadziriswa nesystem yekuona runogona kuwanikwa kubva kugirazi rekamera yeindasitiri. Hunhu hwelenzi yekamera yeindasitirizvichakanganisa zvakananga mashandiro ese ehurongwa hwekuona.
Semhando yemichina yekutora mifananidzo, malenzi ekamera emuindasitiri anowanzo gadzira sisitimu yakakwana yekuwana mifananidzo ine magetsi, kamera, nezvimwewo. Saka, kusarudzwa kwemalenzi ekamera emuindasitiri kunotongwa nezvinodiwa nesystem yese. Kazhinji, inogona kuongororwa nekufungwa kubva pazvinhu zvinotevera:
1.Wavelength uye zoom lens kana kwete
Zviri nyore kusimbisa kana lenzi yekamera yemuindasitiri ichida lenzi ye zoom kana lenzi ye fixed-focus. Kutanga, zvakakosha kuona kana wavelength yekushanda kwelenzi yekamera yemuindasitiri iri pakati pezvinhu. Munguva yekutora mifananidzo, kana kukura kwechinhu kuchidikanwa kuchinjwa, lenzi ye zoom inofanira kushandiswa, zvikasadaro lenzi ye fixed-focus yakakwana.
Nezvekushanda kwewavelength yemagirazi emakamera eindasitiri, bhendi rechiedza chinooneka ndiro rinonyanya kushandiswa, uye kunewo mashandisirwo mune mamwe mabhendi. Pane mamwe matanho ekusefa anodiwa here? Chiedza che monochromatic here kana kuti che polychromatic? Simba rechiedza chisingashande rinogona kudzivirirwa zvinobudirira here? Zvakakosha kuyera zvizere nyaya dziri pamusoro apa usati waona kuti lenzi inoshanda kwenguva yakareba sei.

2.Zvikumbiro zvakakosha zvinokosheswa zvikuru
Zvichienderana nekushandiswa chaiko, panogona kunge paine zvinodiwa zvakakosha. Zvinodiwa zvakakosha zvinofanirwa kutanga zvasimbiswa, semuenzaniso, kana paine basa rekuyera, kana lenzi ye telecentric ichidikanwa, kana kudzika kwefocal yemufananidzo kwakakura zvakanyanya, nezvimwewo. Kudzika kwefocal hakuwanzo kutorwa zvakakomba, asi chero sisitimu yekugadzirisa mifananidzo inofanira kuifungisisa.
3.Kureba kwekushanda uye urefu hwenzvimbo
Kureba kwekushanda nehukuru hwefocal zvinowanzo fungwa pamwe chete. Pfungwa huru ndeyekutanga waona resolution yesystem, wobva wanzwisisa kukura kwayo pamwe chete nehukuru hweCCD pixel, wobva wanzwisisa daro rinogona kuvapo pakati pechinhu nemufananidzo pamwe chete nezvirambidzo zvenzvimbo, kuitira kuti ufungidzire hurefu hwefocal hwelenzi yekamera yeindasitiri.
Saka, kureba kwefocal lens yekamera yeindasitiri kwakabatana nedaro rekushanda kwelens yekamera yeindasitiri uye resolution yekamera (pamwe nehukuru hweCCD pixel).

4.Saizi yemufananidzo uye mhando yemufananidzo
Saizi yemufananidzo welenzi yekamera yeindasitiriKusarudzwa kunofanirwa kunge kunoenderana nehukuru hwepamusoro hwekamera yeindasitiri hunonzwa chiedza, uye nheyo yekuti "yakakura kugamuchira diki" inofanira kuteverwa, kureva kuti, pamusoro pekamera unonzwa chiedza haugone kudarika saizi yemufananidzo inoratidzwa nelenzi, zvikasadaro mhando yemufananidzo wenzvimbo yekuona haigone kuvimbiswa.
Zvinodiwa kuti mifananidzo ive yakanaka zvinoenderana neMTF uye kukanganiswa. Mukushandiswa kwekuyera, kukanganiswa kunofanira kutariswa zvakanyanya.
5.Aperture uye lenzi yekugadzika
Kuvhurika kwemalenzi ekamera eindasitiri kunonyanya kukanganisa kupenya kwepamusoro pemifananidzo, asi mukuona kwemuchina pari zvino, kupenya kwekupedzisira kwemufananidzo kunoenderana nezvinhu zvakawanda zvakaita sekuvhurika, zvidimbu zvekamera, nguva yekubatanidza, chitubu chechiedza, nezvimwewo. Saka, kuti uwane kupenya kwemufananidzo kunodiwa, matanho akawanda ekugadzirisa anodiwa.
Kugadzika lenzi kwekamera yeindasitiri kunoreva nzvimbo inogadzika lenzi nekamera, uye zviviri izvi zvinofanira kuenderana. Kana zviviri izvi zvikasaenderana, panofanira kufungwa nezvekutsiva.

6.Mutengo uye kukura kwetekinoroji
Kana mushure mekufunga zvakadzama nezvezvinhu zviri pamusoro apa, paine mhinduro dzakawanda dzinoenderana nezvinodiwa, unogona kufunga nezvemutengo wakazara uye kukura kwehunyanzvi, wozvipa pekutanga.
PS: Muenzaniso wekusarudza lenzi
Pasi apa tinopa muenzaniso wekuti ungasarudza sei lenzi yekamera yemuindasitiri. Semuenzaniso, sisitimu yekuona muchina yekuona mari inofanira kunge yakashongedzwa nelenzi yekamera yeindasitiri. Zvirambidzo zvinozivikanwa ndeizvi: kamera yeindasitiri CCD ine 2/3 inches, saizi yepikisheni i4.65μm, C-mount, daro rekushanda rakakura kupfuura 200mm, resolution yesystem i0.05mm, uye sosi yechiedza i sosi chena yemwenje ye LED.
Kuongororwa kwekutanga kwekusarudza lenzi ndekwekuti:
(1) Lenzi inoshandiswa nechiedza chena che LED inofanira kunge iri munzvimbo inoonekwa, pasina chinodiwa chekuyedza, uye lenzi ine chigadziko chakasimba inogona kusarudzwa.
(2) Pakuongorora kwemaindasitiri, basa rekuyera rinodiwa, saka lenzi yakasarudzwa inodiwa kuti ive nekukanganisika kushoma.
(3) Kureba kwekushanda uye kureba kwenzvimbo:
Kukura kwemufananidzo: M=4.65/(0.05 x 1000)=0.093
Kureba kwefocal: F= L*M/(M+1)= 200*0.093/1.093=17mm
Kana daro rekutarisa richidikanwa kuti ripfuure 200mm, kureba kwefocal ye lenzi yakasarudzwa kunofanira kupfuura 17mm.
(4) Saizi yemufananidzo welenzi yakasarudzwa haifanirwe kunge iri diki pane fomati yeCCD, kureva kuti, inenge 2/3 inch.
(5) Chinosungirirwa nelenzi chinofanirwa kunge chiri C-mount kuitira kuti chikwanise kushandiswa nemakamera eindasitiri. Hapana chikonzero chekuvhura magirazi panguva ino.
Kuburikidza nekuongorora uye kuverenga zvinhu zviri pamusoro apa, tinogona kuwana "outline" yekutanga yemalenzi ekamera eindasitiri: kureba kwefocal kupfuura 17mm, focus fixed, visible light range, C-mount, inoenderana nehukuru hwe2/3-inch CCD pixel, uye small image distortion. Zvichibva pane zvinodiwa izvi, sarudzo yakawanda inogona kuitwa. Kana malenzi akati wandei achikwanisa kusangana nezvinodiwa izvi, zvinokurudzirwa kuti ugadzirise zvakanyanya uye usarudze lenzi yakanakisa.
Pfungwa Dzekupedzisira:
ChuangAn akaita dhizaini yekutanga uye kugadzirwa kwemagirazi eindasitiri, iyo inoshandiswa muzvinhu zvese zvemaindasitiri. Kana uchida kana kuti uchida magirazi emuindasitiri, ndapota taura nesu nekukurumidza.
