1. Ndemanga

Nkhaniyi ikufotokoza mfundo zamakono, njira zothandizira.

2. Mfundo Zaumisiri

2.1 Optical Defogging

M'chilengedwe, kuwala kowoneka ndi kuphatikiza kwa mafunde osiyanasiyana a kuwala, kuyambira 780 mpaka 400 nm.

Chithunzi 2.1 Spectrograms

Mafunde osiyanasiyana a kuwala amakhala ndi katundu wosiyana, ndipo kutalika kwa kutalika kwake kumalowera kwambiri. Kutalikira kwa utali wa mafunde, m'pamenenso mphamvu yolowera ya mafunde a kuwala imakulirakulira. Iyi ndi mfundo yakuthupi yomwe imagwiritsidwa ntchito pozindikira chifunga chowoneka bwino kuti munthu azitha kuwona bwino lomwe chinthu chomwe mukufuna kulowa mumalo a utsi kapena chifunga.

2.2 Kuwonongeka kwamagetsi

Electronic defogging, yomwe imadziwikanso kuti digito defogging, ndikusintha kwachiwiri kwa chithunzi pogwiritsa ntchito algorithm yomwe ikuwonetsa zinthu zina zomwe zimakonda pachithunzichi ndikuchotsa zomwe zilibe chidwi, zomwe zimapangitsa kuti chithunzicho chikhale bwino komanso zithunzi zowongoka.

3. Njira Zothandizira

3.1 Optical Defogging

3.1.1 Kusankha Bandi

Optical defogging imagwiritsidwa ntchito kwambiri pafupi ndi infrared band (NIR) kuwonetsetsa kulowa ndikulinganiza magwiridwe antchito.

3.1.2 Kusankha kwa Sensor

Pamene chifunga cha kuwala chimagwiritsa ntchito gulu la NIR, chidwi chapadera chiyenera kuperekedwa pakukhudzidwa kwa gulu la kamera la NIR posankha sensa ya kamera.

3.1.3 Kusankha Zosefera

Kusankha fyuluta yoyenera kuti igwirizane ndi zomverera za sensa.

3.2 Kuwonongeka kwamagetsi

Ma algorithm a Electronic Defogging (Digital Defogging) amatengera mawonekedwe a chifunga chakuthupi, chomwe chimatsimikizira kuchuluka kwa chifunga ndi kuchuluka kwa imvi mdera lanu, motero amapezanso chithunzi chowoneka bwino, chifunga-chaulere. Kugwiritsa ntchito chifunga cha algorithmic kumateteza mtundu woyambirira wa chithunzicho ndipo kumapangitsa kuti chifunga chikhale pamwamba pa chifunga cha kuwala.

4. Kufananiza Magwiridwe

Magalasi ambiri omwe amagwiritsidwa ntchito m'makamera owonera makanema nthawi zambiri amakhala ma lens afupiafupi, omwe amagwiritsidwa ntchito kwambiri kuyang'anira zochitika zazikulu zokhala ndi ngodya zazikulu zowonera. Monga momwe chithunzi chili m'munsimu (Zotengedwa kuchokera pafupifupi kutalika kwa 10.5mm).

Chithunzi 4.1 Wide View

Komabe, tikamayandikira kuti tiyang'ane pa chinthu chakutali (Pafupifupi 7km kutali ndi kamera), kutulutsa komaliza kwa kamera nthawi zambiri kumatha kukhudzidwa ndi chinyezi chamumlengalenga, kapena tinthu tating'onoting'ono monga fumbi. Monga momwe chithunzi chili m'munsimu (Zotengedwa kuchokera kufupi ndi kutalika kwa 240mm). M’chifanizirochi tingaone akachisi ndi ma pagodas pamapiri akutali, koma mapiri amene ali m’munsi mwawo amaoneka ngati chipika chathyathyathya cha imvi. Kumverera kwathunthu kwa chithunzicho ndi kofiira kwambiri, popanda kuwonekera kwa maonekedwe ambiri.

Chithunzi 4.2 Defog OFF

Tikayatsa mawonekedwe a electronic defog, timawona kusintha pang'ono pakumveka bwino kwa chithunzi ndi kuwonekera, poyerekeza ndi njira yamagetsi ya defog isanayatsidwe. Monga momwe chithunzi chili pansipa. Ngakhale akachisi, ma pagodas ndi mapiri kuseri akadali amdima pang'ono, osachepera phiri lakutsogolo likumva kubwezeretsedwanso ku mawonekedwe ake, kuphatikiza ma pyloni amagetsi apamwamba omwe ali patsogolo.

Chithunzi 4.3 Electronic Defog

Tikayatsa mawonekedwe a fogging optical, mawonekedwe azithunzi nthawi yomweyo amasintha kwambiri. Ngakhale kuti chithunzicho chimasintha kuchokera ku mtundu kupita ku wakuda ndi woyera (Popeza NIR ilibe mtundu, muzochita zamakono zamakono titha kugwiritsa ntchito mphamvu zomwe zimawonetsedwa ndi NIR ku chithunzi), kumveka bwino ndi kusinthasintha kwa chithunzicho kumakhala bwino kwambiri komanso ngakhale zomera. pamapiri akutali akuwonetsedwa momveka bwino komanso mochulukirapo atatu-njira yowoneka bwino.

Chithunzi 4.4 Optical Defog

Kufananiza kwa magwiridwe antchito kwambiri.

Mpweya umakhala wodzaza ndi madzi pambuyo pa mvula kotero kuti n'kosatheka kuwona kupyolera muzinthu zakutali pansi pazikhalidwe zabwino, ngakhale ndi makina otsegula magetsi. Pokhapokha akayatsidwa chifunga chowoneka bwino, akachisi ndi ma pagoda amatha kuwoneka patali (pafupifupi 7km kutali ndi kamera).
