Kuchaziwe Amakhamera Okufanekisa Okushisayo

Amakhamera wesithombe esishisayo angamathuluzi ahumusha amandla okushisa (ukushisa) ekukhanyeni okubonakalayo ukuze kuhlaziywe into ethile noma indawo ethile. Isithombe esikhiqizwayo saziwa ngokuthi i-thermogram futhi sihlaziywa ngenqubo ebizwa ngokuthi i-thermogram. Amakhamera ezithombe ezishisayo angamadivayisi ayinkimbinkimbi acubungula isithombe esithwetshiwe futhi asibonise esikrinini. Lezi zithombe zingasetshenziselwa ukuxilongwa ngokushesha noma zicutshungulwe ngesofthiwe ekhethekile ukuze kuqhutshekwe nokuhlolwa, ukunemba kanye nokuphuma kombiko. Amakhamera wezithombe ezishisayo athatha izinga lokushisa alibeke ezingeni elilandelayo; esikhundleni sokuthola inombolo yezinga lokushisa uthola isithombe esibonisa umehluko wokushisa kwendawo.

Abonani Amakhamera Okufanekisa Okushisayo?
Ukukhanya okubonakalayo yilokho esikubona eduze kwethu nsuku zonke. Iwukuphela kwengxenye ye-spectrum kagesi esingayibona. Ukukhanya okubonakalayo kuthatha kuphela indawo encane ku-spectrum kagesi kanye nemisebe ye-infrared (IR) imele amaphesenti amakhulu. Uma sifuna ukubona ukuthi kwenzekani kwezinye izingxenye ze-spectrum sidinga imishini ekhethekile.
Zonke izinto zimunca, zibonise futhi ngezinye izikhathi zidlulise amandla emazingeni ahlukene. Izinto ezihlukene zizokhipha ukushisa noma amandla abandayo ngamanani ahlukene. Lawa mandla angatholwa ngemishini ye-infrared futhi aboniswe njengezithombe.

Izicelo Nokusetshenziswa Kwekhamera Yokufanekisa Okushisayo
Ekuqaleni yakhelwe ukusetshenziswa kwezempi phakathi neMpi YaseKorea, amakhamera ezithombe ezishisayo athuthele kwezinye izinkambu futhi athole ukusetshenziswa okuningi. Izicishamlilo zizisebenzisa ukuze zibone ngentuthu, bathole abantu futhi baveze izindawo ezinomlilo. Abomthetho basebenzisa ubuchwepheshe ukuze balawule imisebenzi yokugada, bathole futhi babambe abasolwa, baphenye izigcawu zobugebengu futhi benze imisebenzi yokusesha nokuhlenga. Ochwepheshe bokulungisa izintambo zikagesi bathola amajoyinti ashisisa ngokweqile nezingxenye ukuze baqede ukwehluleka okungenzeka. Lapho ukwahlukanisa okushisayo kuba nephutha, ochwepheshe bokwakha izakhiwo bangabona ukuvuza kokushisa ukuze bathuthukise ukusebenza kahle kokupholisa noma ukushisisa. Imisebenzi ye-physiological, efana nemfiva, kubantu nezinye izilwane ezinegazi elifudumele nazo zingabhekwa nge-imaging thermographic. Futhi zingamathuluzi ajwayelekile asetshenziswa abahloli basekhaya.

Izici zekhamera yesithombe esishisayo
Amakhamera ezithombe ezishisayo angathengwa ngobuncane obuncane bezici ezifunda kuphela izinga lokushisa le-crosshair ephakathi nendawo esibonisini noma anezici eziningi ezivumela umsebenzisi ukuthi akhethe ama-crosshair amaningi anyakazayo futhi enze ukuqhathanisa phakathi kwawo ukuze abonise izinga lokushisa eliphezulu, eliphansi nelimaphakathi esibonisini. Amakhamera ezithombe ezishisayo anamaphalethi emibala amaningi angakhethwa umsebenzisi, afana nomnyama/omhlophe, insimbi noma uthingo. Iphalethi yensimbi isetshenziswa kakhulu ngabahloli basekhaya. Iphalethi emnyama/emhlophe isiza ukukhomba imininingwane esithombeni, futhi iphalethi yothingo inokuzwela okushisayo okuhamba phambili kokubonisa umehluko ezingeni lokushisa. Bona isampula yezithombe ngezansi zamanye amaphalethi ombala.

Okufanele Ukubheke Kukhamera Yokuthwebula Okushisayo
Kunenombolo yezingxenye ezifaka isandla kukho kokubili ikhwalithi kanye nezindleko zekhamera yokuthwebula eshisayo. Izinto ezimbili ezibaluleke kakhulu ukuxazulula umtshina kanye nokuzwela kwe-thermal.
Ukulungiswa komtshina kuchaza inani lamaphikseli. Izinqumo ezivame kakhulu amaphikseli angu-160 x 120, 320 x 240 kanye namaphikseli angu-640 x 480. Umtshina ongu-320 x 240 ukhiqiza isithombe esakhiwe ngamaphikseli angu-76,800. Njengoba iphikseli ngalinye linezinga lokushisa elihambisana nalo elingamaphuzu wedatha wokushisa angama-76,800. Izinqumo eziphakeme zibuye zikhiqize izithombe ezicace ngokusobala.
Ukuzwela kwe-thermal umehluko omncane wezinga lokushisa ongawuzwa ikhamera. Ukuzwela okungu-0.05° kusho ukuthi ikhamera ingakwazi ukuhlukanisa phakathi kwezindawo ezimbili ezinomehluko wamakhulu amahlanu kuphela wezinga lokushisa ledigri.
Esinye isici esibalulekile okufanele sicatshangelwe izinga lokushisa lekhamera ethwebulayo eshisayo. Ububanzi butshela ukuthi yimaphi amazinga okushisa amancane naphezulu ikhamera engawakala (-4°F kuya ku-2200°F kuyinto evamile).
Ukuze uthole isithombe esishisayo esingcono kakhulu ongasihlaziya, kukhona ukulungiswa okune okungenziwa kumakhamera amaningi: ukugxila, izinguquko zesethingi yokukhipha umoya, izinguquko zesilungiselelo sokushisa esikhanyayo kanye nokushuna okushisayo. Ngayinye yalezi zinguquko kufanele icatshangelwe lapho kukhethwa ikhamera yokuthwebula eshisayo.
Njengekhamera evamile, ilensi yekhamera yokuthwebula eshisayo idinga ukugxila ukuze kuthuthukiswe ukucaca kwesithombe. Amakhamera amaningi angagxila ngokusonta ilensi. Amakhamera athuthuke kakhulu anokugxila kwenkinobho yokucindezela.
I-Emissivity inani lemisebe ekhishwa entweni uma iqhathaniswa neyomshini okhipha imisebe ophelele lapho kokubili kusezingeni lokushisa elifanayo. Ukulungisa ukukhishwa komoya okungcolile kubalulekile lapho uthatha izilinganiso zezinga lokushisa noma uma uqhathanisa amazinga okushisa ezinto ezimbili ezihlukene. Akuwona wonke amakhamera avumela umsebenzisi ukuthi afake izinga lokushisa elikhanyayo.
Ukulungiselelwa kwezinga lokushisa elikhanyayo kuvumela umsebenzisi ukuthi anxephezele ngezinga lokushisa lezinto ezizungezile elibonisa entweni. Njengokukhipha umoya, izinga lokushisa elikhanyayo libalulekile uma uthatha izilinganiso zokushisa noma uqhathanisa amazinga okushisa ezinto ezimbili. Akuwona wonke amakhamera avumela umsebenzisi ukuthi afake izinga lokushisa elikhanyayo.
Ukushuna okushisayo ikhamera kubandakanya ukulungisa ubude besikhathi noma izinga lokushisa elibonwa ikhamera ngenkathi ikumodi yokuzibuka mathupha. Imodi eyenziwa mathupha ivumela umsebenzisi ukuthi alungise ubude bebanga elifiselekayo, futhi ikhamera izohlala ibonisa leli banga lokushisa. Ukusebenzisa imodi yezandla kuhle kakhulu uma kusetshenziselwa ukuveza umehluko wokushisa wento ebukwayo.

Imikhawulo yekhamera yesithombe esishisayo
Ngenxa yokuthi amandla ashisayo angabonakala ezindaweni ezicwebezelayo, amakhamera ezithombe ezishisayo awakwazi ukubona ngengilazi. Amakhamera ezithombe ezishisayo angasetshenziswa ukuqoqa ulwazi mayelana nengaphakathi
 zodonga, kodwa azikwazi ukubona ngezindonga. Kubalulekile futhi ukwazi ukuthi amakhamera wokuthwebula ashisayo akufanele asetshenziswe njengokuwukuphela kwesici esinqumayo sokuthi inkinga ekhona. Ukusebenzisa ezinye izinsimbi kufanele kusetshenziswe njalo ukuqinisekisa inkinga.
