Yaya tsawon mai da hankali zai shafi sakamakon samfurin 3D

1 ction Gabatarwa

Don ɗaukar hoto mara kyau, akwai shimfidar wurare huɗu waɗanda suke da wuyar gina samfuran 3D:

 

Matsayi mai nunawa wanda ba zai iya yin bayanin ainihin rubutun abu na abu ba.Misali, farfajiyar ruwa, gilashi, babban yanki gine-ginen kayan zane guda.

 

Abubuwa masu saurin tafiya. Misali, motoci a mahada

 

Yankuna inda wuraren-fasalin ba za su iya daidaitawa ba ko daidaitaccen fasalin-maki suna da manyan kurakurai, kamar bishiyoyi da daji.

 

M gine-gine hadaddun. Kamar shingen tsaro, tashoshin tushe, hasumiyoyi, wayoyi, da sauransu.

Na yanayi na 1 da na 2, komai yadda za'a inganta ingancin bayanan asali, ƙirar 3D ba zata inganta ba.

 

Naufin 3 da nau'in 4 na yanayi, a cikin ainihin aiki, zaku iya inganta ƙirar samfurin 3D ta hanyar inganta ƙuduri, amma har yanzu yana da sauƙin samun ɓoyo da ramuka a cikin samfurin, kuma ingancin aikinsa zai zama ƙasa kaɗan.

 

Baya ga al'amuran na musamman na sama, a cikin tsarin samfurin 3D, abin da muke mai da hankali sosai shi ne ƙirar ƙirar 3D na gine-ginen. Saboda matsalolin da ke da alaƙa da saitin saitin jirgi, yanayin haske, kayan samin bayanai, kayan kwalliyar 3D, da sauransu, kuma yana da sauƙi a sa ginin ya nuna: fatalwa, zane, narkewa, ɓarna, nakasawa, mannewa, da sauransu. .

 

Tabbas, matsalolin da muka ambata a sama suma za'a iya inganta su ta hanyar samfurin 3D-gyara. Koyaya, idan kuna son aiwatar da aikin garambawul na manyan samfura, tsadar kuɗi da lokaci zasuyi yawa.

A matsayinka na mai kerar R&D na kyamarori masu karkarwa, Rainpoo yana tunani ne ta mahallin tattara bayanai:

Yadda ake tsara kyamara mara kyau don samun nasarar inganta ƙirar ƙirar 3D ba tare da ƙara haɗuwa da hanyar jirgin ko yawan hotuna ba?

2 Menene tsawon hankali

Tsawon zangon ruwan tabarau abu ne mai matukar mahimmanci.Yana ƙayyade girman abin da ake magana akan matsakaiciyar hoton, wanda yayi daidai da ma'aunin abin da hoton. Lokacin amfani da kyamarar tsayayyar dijital (DSC), firikwensin yafi CCD da CMOS. Lokacin da aka yi amfani da DSC a cikin iska -survey, tsayin mai da hankali zai ƙayyade nisan samfurin ƙasar (GSD).

A yayin harba abu guda da aka nufa a wuri daya, a yi amfani da tabarau mai dogon hankali, hoton wannan abu yana da girma, kuma ruwan tabarau mai gajere mai tsawo karami ne.

Tsawon mai da hankali yana ƙayyade girman abu a cikin hoto, kusurwar kallo, zurfin filin da yanayin hoton. Dogaro da aikace-aikacen, tsayin mai da hankali zai iya zama daban, daga ngingan mm zuwa metersan mitoci. Gabaɗaya, don ɗaukar hoto ta sama, mun zaɓi, mun zaɓi tsayin mai da hankali a kewayon 20mm ~ 100mm.

3 Menene FOV

A cikin tabarau na gani, kusurwar da aka kafa ta tsakiyar tsakiyar ruwan tabarau azaman koli da kuma iyakar zangon hoton abin da zai iya wucewa ta cikin tabarau ana kiran shi kusurwar kallo. Girman FOV, ƙaramin girman gani. A cikin sharuddan, idan abin da ake niyya baya cikin FOV hasken da yake bayyana ko kuma abin da yake fitarwa ba zai shiga tabarau ba kuma hoton ba zai samu ba.

4, Focal tsawon & FOV

Don tsinkayen kyamarar kyamara, akwai rashin fahimtar juna guda biyu:

 

1) Tsawon tsayin daka, mafi girman tsayin drones, kuma ya fi girma yankin da hoton ke iya rufewa;

2) Tsawon tsayin daka, mafi girman yankin ɗaukar hoto kuma mafi girman aikin aiki;

Dalilin rashin fahimta guda biyu da ke sama shine cewa ba a san haɗin tsakanin tsayin daka da FOV ba. Haɗin haɗin tsakanin su biyu shine: tsayin mai da hankali, ƙarami da FOV; ya fi guntu mai tsayi, ya fi girma FOV.

Sabili da haka, lokacin da girman jikin firam ɗin, ƙudurin firam ɗin, da ƙudurin bayanai suka kasance iri ɗaya, canji a cikin tsayin daka zai canza tsayin jirgin ne kawai, kuma yankin da hoton ke rufewa bai canza ba.

5, Focal length & Aiki Ingantacce

Bayan fahimtar alaƙar da ke tsakanin mai da hankali da kuma FOV, kuna iya tunanin cewa tsawon tsayin daka ba shi da wani tasiri a kan ingancin tashin jirgin. Ga Ortho-photogrammetry, ya zama daidai daidai (tsananin magana, tsawon tsayin mai da hankali, mafi girma tsayin jirgin, mafi yawan kuzarin da yake amfani da shi, gajartar lokacin tashi ne da kuma raguwar ingancin aiki).

Don ɗaukar hoto, wanda ya fi tsayi mai mahimmanci, ƙananan ƙimar aiki ne.

Ana sanya ruwan tabarau mara kyau na kamara a kusurwar 45 °, don tabbatar da cewa an tattara bayanan hoto na fuskar gefen gefen yankin da aka nufa, ana buƙatar faɗaɗa hanyar jirgin.

Saboda ruwan tabarau an rufe shi da 45 °, za a samar da alwatika mai daidaitaccen isosceles. Da yake cewa ba a yin la'akari da halin jirgin mara matuki, babban abin hangen nesa na ruwan tabarau ana ɗauke shi zuwa gefen yankin awo kamar yadda ake buƙatar hanyar tsara hanya, to hanyar drone tana faɗaɗa tazara daidai da daidaito zuwa tsayin jirgin na drone .

Don haka idan yankin ɗaukar hanyar hanya ba ta canzawa, hakikanin wurin aiki na gajeren ruwan tabarau mai mahimmanci ya fi na dogon ruwan tabarau girma.
