1. Abstract

Ichi chinyorwa chinoburitsa nheyo dzehunyanzvi, nzira dzekushandisa.

2. Nhungamiro dzehunyanzvi

2.1 Optical defogging

Mune zvakasikwa, mwenje unoonekwa musanganiswa wezvakasiyana wavelengths wechiedza, kubva ku780 kusvika 400 nm.

Mufananidzo 2.1 Spectrograms

Iyo yakasarudzika wavelength yechiedza ine zvivakwa zvakasiyana, uye yakareba iyo wavelength, iyo ichipinda zvakanyanya. Iyo yakareba iyo wavelength, iyo yakakura simba simba rekupinza kwechiedza chimedu. Iyi ndiyo nheyo yepanyama inoshandiswa neyekuona kweiyo fog kuwanikwa kuti uwane mufananidzo wakajeka wechinhu chakanangana nechinhu chakanangana neine smoky kana foggy nharaunda.

2.2 zvemagetsi defogging

Kudonhedzwa kwemagetsi, kunozivikanwawo seDhijitari Defogging, ndiko kugadzirwa kwechipiri kwemufananidzo nea algorithm kunoratidza zvimwe zvinangwa zvechifananidzo mumufananidzo uye zvinokonzerwa nekuvandudzwa kwemifananidzo yemhando yemifananidzo uye kuvandudzwa mifananidzo.

3. Nzira Dzinoshandisa

3.1 Optical defogging

3.1.1 bhendi kusarudzwa

Optical defogging inonyanya kushandiswa muBound Infrared Band (nir) kuve nechokwadi chekupinza panguva yekuenzanisa kufungidzira.

3.1.2 Sensor Sarudzo

Sekusimuka kwechiitiko kunoratidza iyo nir band, kutarisirwa kwakakosha kunofanirwa kubhadharwa kune iyo sensitivity yekamera yekamera nir band mukusarudzwa kwekamera yekamera.

3.1.3 Filter Kusarudzwa

Kusarudza iyo yekurudyi firita kuti ifanane nehunhu hwekunzwisisa hwe sensor.

3.2 zvemagetsi defogging

Iyo yemagetsi yekudzora Iko kushandiswa kweAlgorithmic Fogging inochengetedza ruvara rwepakutanga rwechifananidzo uye zvakanyanya inovandudza maitiro ekutsvaira pamusoro pekutsvaira kwechokwadi.

4. Performance kuenzanisa

Zvizhinji zvezvinyorwa zvinoshandiswa mumavhidhiyo ekuratidzira makamera inonyanya kupfupi kureba arega, ayo anonyanya kushandiswa kuongorora zviyero zvakakura zvine mapepa ekuona. Sezvinoratidzwa mumufananidzo uri pazasi (kutorwa kubva kune yakaenzana yekufungidzira urefu hwe10,5mm).

Mufananidzo 4.1 Wide Tarisa

Nekudaro, kana isu tazotarisa pachinhu chinorehwa nechinhu chiri kure (chinenge che7km kure nekamera), iyo yekupedzisira yekamera inogona kuunganidzwa neyeyemhepo unyoro, kana zvidiki zvidiki seguruva. Sezvinoratidzwa mumufananidzo uri pazasi (kutorwa kubva pane yakaenzana yekufungidzira urefu hwe 240mm). Mumufananidzo watinogona kuona matembere uye pagodhi pamakomo ari kure, asi zvikomo zviri pasi pevakaratidzika kunge grey grey block. Iko kunzwa kwakazara kwemufananidzo kunhinga zvakanyanya, pasina kujeka kwemaonero akawandisa.

Mufananidzo 4.2 Defog Off

Kana isu tikatendeukira kumagetsi defog mode, tinoona kushoma kwekuvandudzwa mumifananidzo kujekesa uye kujeka, tichienzanisa pamberi peiyo yemagetsi defog mode yakavhurwa. Sezvakaratidzwa mumufananidzo pazasi. Kunyangwe tembere, pagodhi uye zvikomo kumashure zvichiri kuseri kwechikara zvishoma, kanokwana chikomo pamberi pekunzwa kudzoreredzwa kuoneka kwayo, kusanganisira iyo yakakwira voltage magetsi epylons mberi mberi.

Mufananidzo 4.3 Electronic defog

Kana isu tikatendeukira pane iyo Optical fogging mode, iyo magetsi maitiro anokurumidza kuchinja zvakanyanya. Kunyangwe iyo mufananidzo uchinja kubva kune ruvara kusvika kune nhema uye chena (kubva nir isina ruvara, mukunyatsoita emagetsi Pane zvikomo zviri kure zvinoratidzwa mune yakajeka zvakanyanya uye zvimwe zvitatu - nzira huru.

Mufananidzo 4.4 Optical defog

Kuenzanisa kwekunyanyisa chiitiko kuita.

Mhepo izere nemvura mushure memvura kuti hazvigone kuona kuburikidza nezvinhu zviri kure zvinhu mumamiriro ezvinhu akajairika, kunyangwe neyemagetsi defogging mode. Chete kana fogging yemitambo ichichinjiswa pane inogona tembere uye pagodas inoonekwa iri kure (nezve 7km kure nekamera).

Mufananidzo 4.5 e - defog
