Zinthu zonse zimatulutsa mphamvu ya infuraredi (kutentha) malinga ndi kutentha kwawo.Mphamvu ya infrared yomwe imatulutsidwa ndi chinthu imatchedwa chizindikiro chake cha kutentha.Nthawi zambiri, chinthu chikamatentha kwambiri, m'pamene chimatulutsa ma radiation ambiri.Thermal imager (yomwe imadziwikanso kuti thermal imager) kwenikweni ndi sensor yotentha, yomwe imatha kuzindikira kusiyana pang'ono kwa kutentha.Chipangizochi chimasonkhanitsa ma radiation a infrared kuchokera kuzinthu zomwe zili pamalopo ndikupanga zithunzi zamagetsi potengera zambiri za kusiyana kwa kutentha.Popeza kuti zinthu sizimakhala pa kutentha kofanana ndendende ndi zinthu zina zozungulira, zimatha kuzindikirika ndi chojambula chotenthetsera, ndipo zimawonekera momveka bwino pamatenthedwe.
Zithunzi zotentha nthawi zambiri zimakhala zotuwa m'chilengedwe: zinthu zakuda zimakhala zozizira, zoyera zimakhala zotentha, ndipo kuya kwa imvi kumasonyeza kusiyana pakati pa ziwirizi.Komabe, zithunzi zina zotentha zimawonjezera mtundu pachithunzichi kuti zithandize ogwiritsa ntchito kuzindikira zinthu zomwe zimatentha mosiyanasiyana.
Kodi kujambula kwamafuta ndi chiyani?
Chifaniziro cha kutentha kwa infrared chimatha kusintha kutentha (ie mphamvu ya kutentha) kukhala kuwala kowonekera, kuti athe kusanthula chilengedwe.Izi zimawapangitsa kukhala osinthasintha kwambiri.Zida zamoyo ndi zamakina zimatulutsa kutentha ndipo zimatha kuwonedwa ngakhale mumdima.Zithunzi zotenthazi ndizolondola kwambiri ndipo zimagwira ntchito bwino ndi kutentha kochepa chabe.
Kodi kujambula kwa kutentha kumagwira ntchito bwanji?
Kuwala kowoneka ndi kothandiza kwambiri kwa anthu ndi zamoyo zina, koma ndi gawo laling'ono chabe la ma electromagnetic spectrum.Ma radiation a infrared opangidwa ndi kutentha amatenga "malo" ambiri mu sipekitiramu.Chojambula chotenthetsera cha infrared chimajambula ndikuwunika momwe kutentha kwatengedwera, kowoneka bwino komanso nthawi zina kufalikira.
Mulingo wa radiation yotentha yotulutsidwa ndi chinthu umatchedwa chizindikiro chake chamafuta.Kutentha kwa chinthu chopatsidwa, m'pamenenso chimawonekera kwambiri m'chilengedwe.Chojambula chotentha chimatha kusiyanitsa pakati pa gwero la kutentha ndi kusiyana kwakung'ono kwa ma radiation a kutentha.Imasonkhanitsa deta iyi mu "mapu otentha" athunthu kuti asiyanitse ndi msinkhu wa kutentha.
Kodi kujambula kwamafuta ndi kotani?
Poyamba ankagwiritsidwa ntchito pozindikira usiku komanso kumenyana.Kuyambira pamenepo, akhala akukonzedwa kuti agwiritsidwe ntchito ndi ozimitsa moto, akatswiri amagetsi, ogwira ntchito pazamalamulo ndi magulu opulumutsa anthu m'madera atsoka.Amagwiritsidwanso ntchito kwambiri poyang'anira nyumba, kukonza ndi kukhathamiritsa.
Kodi kuzindikira matenthedwe kujambula?
Kujambula kwamafuta kumatha kukhala ukadaulo wophatikizika komanso wothandiza.Chojambula chosavuta kwambiri chotenthetsera chimatha kuyesa gwero la kutentha lomwe lili pakati pa crosshair.Machitidwe ovuta kwambiri amapereka mfundo zambiri zofananitsa, kotero ogwiritsa ntchito akhoza kusanthula zochitika zachilengedwe.Chithunzi chojambula chotentha chimasiyana kwambiri, kuchokera pamtundu wa monochrome kupita ku "pseudo color" wathunthu.
Kodi muyenera kuyang'ana chiyani pazida zojambulira zotentha?
Makamaka, kufunikira kwanu kwa chojambula chotentha kumatengera malo omwe mumagwiritsa ntchito.Komabe, madera awiri ndi zinthu zazikuluzikulu zosiyanitsira zithunzi zamafuta: kukonza kwa detector ndi kutentha kwamafuta.
Monga zisankho zina zambiri, kusamvana kumafotokoza kuchuluka kwa ma pixel - mwachitsanzo, kusamvana kwa 160 × 120 kumakhala ndi ma pixel a 19200.Pixel iliyonse imakhala ndi deta yokhudzana ndi kutentha, kotero kusintha kwakukulu kungapangitse chithunzi chomveka bwino.
Kutentha kwa kutentha ndiko kusiyana komwe kumatha kuzindikirika ndi wojambula.Mwachitsanzo, ngati tilinazo chipangizo ndi 0,01 °, zinthu ndi kutentha kusiyana pa zana akhoza kusiyanitsidwa.Kutentha kocheperako komanso kopitilira muyeso ndikofunikiranso.
Zithunzi zotentha zimakhala ndi zoletsa zina: mwachitsanzo, sizingadutse pagalasi chifukwa cha mawonekedwe azinthu.Amatha kuonabe koma satha kulowa khoma.Komabe, kujambula kwamafuta kwakhala kothandiza m'mapulogalamu ambiri.
