5. Daga DG3 zuwa DG3Pros

RIY-Pros jerin kyamarori mara kyau na iya cimma ingantacciyar ingancin ƙirar ƙira. Don haka wane tsari na musamman ne Ribobi ke da shi a cikin shimfidar ruwan tabarau da saitin tsayi mai tsayi? A cikin wannan fitowar, za mu ci gaba da gabatar da ƙirar ƙira a bayan sigogin Ribobi.

6, Oblique ruwan tabarau kwana da kuma yin tallan kayan kawa ingancin

Abubuwan da suka gabata sun ambaci irin wannan ra'ayi: mafi guntu tsayin tsayin daka, girman kusurwar kallo, ƙarin bayanan facade na ginin za a iya tattarawa, kuma mafi kyawun ƙirar ƙirar ƙira.

Baya ga saita tsayin daka mai ma'ana, ba shakka, zamu iya amfani da wata hanya don inganta tasirin ƙirar ƙira: kai tsaye ƙara kusurwar ruwan tabarau na oblique, wanda kuma zai iya tattara bayanan facade da yawa.

Amma a zahiri, ko da yake kafa babban kusurwa mai girma na iya inganta ingancin ƙirar, akwai kuma illa guda biyu:

1: Ingantaccen aiki zai ragu. Tare da karuwar madaidaicin kusurwa , fadada waje na hanyar jirgin zai kuma ƙara da yawa. Lokacin da madaidaicin kusurwar ya wuce 45 °, ingancin jirgin zai ragu sosai.

Misali, ƙwararriyar kyamarar iska Leica RCD30, kusurwar da ba ta dace ba ce kawai 30 °, ɗayan dalilan wannan ƙirar shine haɓaka ingantaccen aiki.

Kyamarar ruwan ruwan sama shine farkon wanda ya fara ɗaukar ƙirar ruwan tabarau na ciki. Wannan ƙira yana daidai da ƙara hood zuwa ruwan tabarau don hana shi daga tasirin hasken rana.

Musamman ga ƙananan jirage marasa matuki, gabaɗaya, halayen jirgin su ba su da kyau. Bayan kusurwar ruwan tabarau da kuma halayen jirgin mara matuki sun mamaye, batattun haske na iya shiga cikin kamara cikin sauƙi, yana ƙara haɓaka matsalar kyalli.

7. Hanyar zoba da kuma yin tallan kayan kawa ingancin

Bisa ga kwarewa, don tabbatar da ingancin samfurin, ga kowane abu a cikin sararin samaniya, yana da kyau a rufe bayanan rubutu na ƙungiyoyi biyar na ruwan tabarau a lokacin jirgin.

Wannan yana da sauƙin fahimta. Misali, idan muna son gina samfurin 3D na wani tsohon gini, ingancin ƙirar jirgin da'irar dole ne ya fi ingancin ɗaukar hotuna kaɗan kawai a bangarori huɗu.

Ƙarin hotuna da aka rufe, ƙarin sararin sarari da bayanan rubutu da ke cikinsa, kuma mafi kyawun ingancin ƙirar ƙira. Wannan shine ma'anar haɗuwar hanyar jirgin don ɗaukar hoto.

Matsayin haɗuwa yana ɗaya daga cikin mahimman abubuwan da ke ƙayyade ingancin ƙirar 3D. A cikin yanayin gaba ɗaya na ɗaukar hoto, ƙimar haɗin gwiwa galibi tana kan kai kashi 80% kuma kashi 70% a gefe (ainihin bayanan ba su da yawa).

A gaskiya ma, yana da kyau mafi kyau don samun nau'i iri ɗaya na zoba na gefe, amma maɗaukakiyar haɗe-haɗe da yawa zai rage tasirin jirgin sama sosai (musamman don ƙayyadaddun fuka-fuki drones), don haka dangane da yadda ya dace, haɗin kai na gaba ɗaya zai zama ƙasa da ƙasa. jeri zoba.

Tukwici: Idan aka yi la'akari da ingancin aiki, digirin da ba ya wuce gona da iri ba shi da yawa. Bayan ƙetare wani “misali”, haɓaka matakin haɗe-haɗe yana da iyakataccen tasiri akan ƙirar 3D. Bisa ga ra'ayoyin mu na gwaji, wani lokacin haɓaka haɗin gwiwa zai rage ingancin samfurin. Misali, don wurin ƙirar ƙirar ƙuduri na 3 ~ 5cm, ƙimar ƙirar ƙirar ƙananan digiri wani lokaci ya fi mafi girman digiri.

8. Bambanci tsakanin ka'idar zoba da ainihin zoba

Kafin tashin jirgin, mun saita 80% kan gaba da 70% na gefe, wanda shine kawai karo na ka'idar. A cikin jirgin, jirgin zai yi tasiri ta hanyar iska.kuma canjin hali zai sa ainihin abin da ya faru ya zama ƙasa da abin da aka kwatanta.

Gabaɗaya, ko na'ura mai ba da hanya tsakanin hanyoyin sadarwa ce ko mara ƙarfi mai ƙarfi, mafi ƙarancin halayen jirgin, mafi muni da ingancin ƙirar 3D. Saboda ƙaramin juzu'in juzu'i ko ƙayyadaddun jirage marasa ƙarfi sun fi nauyi a nauyi kuma sun fi girma, suna da saurin tsangwama daga kwararar iska ta waje.
