Uyu mubvunzo une musoro asi hauna mhinduro iri nyore. Pane zvinhu zvakawanda zvinogona kukanganisa mhedzisiro, zvakaita sekuderera kwemamiriro ekunze akasiyana, kunzwa kwechinhu chinoona kupisa, algorithm yekufungidzira, ruzha rwepasi uye rwekumashure, uye musiyano wekupisa kwemashure. Semuenzaniso, chibato chefodya chinoonekwa zviri nyore kupfuura mashizha ari pamuti uri padaro rimwe chete kunyangwe chiri chidiki zvakanyanya, nekuda kwemusiyano wekupisa kwemashure.
Kureba kwekuona chinhu kunokonzerwa nekusanganiswa kwezvinhu zvinoonekwa nemunhu uye zvinhu zvinoonekwa nemunhu. Izvi zvine chekuita nepfungwa dzemuoni, ruzivo rwake nezvimwe zvinhu. Kuti tipindure kuti "kamera yekupisa inogona kuona kusvika papi", tinofanira kutanga taziva kuti zvinorevei. Semuenzaniso, kuti tizive chinangwa, nepo A achifunga kuti anogona kuchiona zvakajeka, B angasachiona. Saka, panofanira kuva nechiyero chekuongorora chakabatana uye chakanangana.
Zvinodiwa naJohnson
Johnson akaenzanisa dambudziko rekuona maziso nemitsara miviri zvichienderana nekuyedza. Mitsetse miviri inhambwe iri pakati pechiedza chakafanana nemutsetse werima pamuganhu wekuona kwemuoni. Mitsetse miviri yakaenzana nemapikiseli maviri. Ongororo dzakawanda dzakaratidza kuti zvinokwanisika kuziva kugona kwekuona chinangwa che infrared thermal imager system nekushandisa mitsara miviri pasina kufunga nezvehunhu hwezvikanganiso zvechinangwa nemufananidzo.
Mufananidzo wechinangwa chimwe nechimwe chiri mufocal plane unobata mapikiseli mashoma, anogona kuverengerwa kubva pahukuru, daro riri pakati pechinangwa nemufananidzo wekupisa, uye instantaneous field of view (IFOV). Chiyero chehukuru hwechinangwa (d) nedaro (L) chinonzi aperture angle. Inogona kukamurwa neIFOV kuti uwane huwandu hwemapikiseli anotorwa nemufananidzo, kureva kuti, n = (D / L) / IFOV = (DF) / (LD). Zvinogona kuonekwa kuti kureba kwefocal kwakakura, mapoinzi makuru anotorwa nemufananidzo wechinangwa. Sekureva kweJohnson criterion, daro rekuona rakareba. Kune rumwe rutivi, kureba kwefocal kwakakura, angle yemunda idiki, uye mutengo wakakwira.
Tinogona kuverenga kuti mufananidzo chaiwo wekupisa unogona kuona kusvika papi zvichibva pane zvishoma zvinoenderana nezvinodiwa naJohnson ndeizvi:
Kuonekwa - chinhu chiripo: 2 +1/-0.5 pixels
Kuzivikanwa - rudzi rwechinhu chinogona kuonekwa, munhu vs. mota: 8 +1.6/-0.4 pixels
Kuzivikanwa - chinhu chaicho chinogona kuonekwa, mukadzi vs. murume, mota chaiyo: 12.8 +3.2/-2.8 pixels
Kuyera uku kunopa mukana we50% wekuti mucherechedzi asarudze chinhu kusvika padanho rakatarwa.
