RIY-Pros jerin ƙirar kamara na ƙila za su iya samun ingancin samfurin mafi kyau. Don haka wane zane na musamman Pros ke da shi a cikin shimfidar ruwan tabarau da kuma saiti mai mahimmanci? A cikin wannan fitowar, zamu ci gaba da gabatar da ƙira-ƙirar dabaru a bayan sigogin Fa'idodi.

6, oblique ruwan tabarau kwana da kuma tallan kayan kawa

Abubuwan da suka gabata sun ambata irin wannan ra'ayi: thean gajarta tsaka mai tsayi, mafi girman kusurwar gani, za a iya tattara ƙarin bayanan facade, kuma mafi ingancin samfurin.

 Baya ga saita tsayi mai ma'ana, ba shakka, za mu iya amfani da wata hanyar don inganta tasirin samfurin. kai tsaye ƙara kusurwar ruwan tabarau mai karkarwa, wanda kuma zai iya tattara ƙarin wadatar bayanan facade.

 

Amma a zahiri, kodayake saita kusurwa mafi girma zai iya inganta ƙirar samfuri, akwai kuma illa biyu:

 

1: Ingancin aiki zai ragu. Tare da karuwar kwana kwana, fadada waje na hanyar tashi shima zai karu sosai. Lokacin da kusurwa mafi ƙarancin ya wuce 45 °, ingancin jirgin zai sauka ƙasa ƙwarai.

Misali, ƙwararren kamarar iska Leica RCD30, kusurwar kusurwa ce kawai 30 °, ɗayan dalilan wannan ƙirar shine ƙara ƙarfin aiki.

2: Idan kusurwar karkatarwa tayi yawa, hasken rana zai shiga cikin kyamara a sauƙaƙe, yana haifar da kyalli (musamman da safe da rana na wani hazo). Rainpoo oblique kamara ita ce farkon da ta ɗauki zane-ruwan tabarau na ciki. Wannan ƙirar ta yi daidai da ƙara kaho a cikin tabarau don hana tasirin hasken rana mai illa.

Musamman ma ga ƙananan jirage marasa matuka, gaba ɗaya, halayen tashi ba su da kyau. Bayan an sanya kusassar ruwan tabarau da kuma halayen drone, hasken ɓata zai iya shiga cikin kyamara a sauƙaƙe, yana ƙara fadada matsalar haskakawa.

7, Hanya zoba da kuma tallan kayan kawa inganci

Dangane da gogewa, don tabbatar da ƙirar ƙirar, ga kowane abu a sararin samaniya, ya fi kyau a rufe bayanin fasalin rukunin ruwan tabarau guda biyar yayin tashi.

 Wannan yana da saukin fahimta. Misali, idan muna son gina tsarin 3D na tsohon gini, ingancin samfurin samfurin jirgin da'irar dole ne ya fi kyau fiye da ingancin ɗaukar onlyan hotuna kaɗan a ɓangarori huɗu.

Arin hotuna da aka lulluɓe, da ƙarin bayanan sararin samaniya da bayanan da yake ƙunshe, kuma mafi ingancin samfurin samfura. Wannan shine ma'anar hanyar jirgin sama don ɗaukar hoto mara kyau.

Matsayin zoba yana ɗaya daga cikin mahimman abubuwan da ke ƙayyade ƙimar samfurin 3D. A cikin gabaɗaya yanayin ɗaukar hoto, ƙididdigar juzu'i galibi 80% ne ke tafiya kuma 70% a kaikaice (ainihin bayanan ba shi da yawa).

A hakikanin gaskiya, hakika mafi kyau shine a sami irin wannan matakin na juzu'i a gefe, amma yin sama sama gefe-gefe zai iya rage tasirin jirgin sama (musamman don jirage marasa matuka), don haka bisa ga inganci, janar kwancen gaba daya zai zama ƙasa da na taken zoba

 

Tukwici: Idan aka yi la'akari da ingancin aiki, digirin da ke kan gado bai kai yadda zai yiwu ba. Bayan wuce wani takamaiman "daidaitaccen", inganta ƙididdigar digiri yana da iyakantaccen sakamako akan ƙirar 3D. Dangane da bayanan gwajinmu, wani lokacin ƙara abin da ke juyewa a zahiri zai rage ƙirar ƙirar. Misali, don yanayin tallan tallan ƙuduri na 3 ~ 5cm, ƙirar samfuri na ƙarancin digiri mai juzuwar wani lokaci ya fi mafi girman juyewar digiri.

8 、 Bambanci tsakanin tsinkayen ka'idoji da ainihin ma'ana

Kafin tafiya, mun saita kashi 80% kuma 70% a gefe, wanda shine kawai abin da ya dace. A cikin jirgin, iska za ta shafar jirgin mara matuki,kuma canjin da ake samu zai haifar da ainihin abin da zai zo da baya.

Gabaɗaya, koda mahaukacin rotor ne ko kuma matattara mai tsayayyen jirgi, mafi ƙarancin halin tashi, mafi munin ingancin ƙirar 3D.
