Özet:

 The city is a settlement unit where trade, industry, and infrastructure services are densely located, with areas of residence containing elements such as people, buildings, and infrastructure. Buildings, as one of these elements, typically have structural features like roofs, walls, and floors. The prevalence, purpose, and design of buildings provide information about the economic and social structure of the city they are in; for example, complex buildings are seen in metropolises, while simple building types are observed in rural areas. Complex buildings, being structurally challenging in design and construction, should be modeled in 3D to enhance visual understanding, facilitate spatial arrangements, and provide engineers with greater control over building design. Depending on the suitability of the project, users may choose methods such as digital processing, laser scanning, or photogrammetry for modeling. Photogrammetry is a method that uses the analysis of photographs to determine the 3D coordinates and shapes of objects. This method enables the creation of 3D models of objects. In contemporary 3D modeling processes, photogrammetrys subfield known as UAV Unmanned Aerial Vehicle photogrammetry is often preferred. UAV photogrammetry involves collecting images using unmanned aerial vehicles and is known as a fast and cost-effective method. In this study, UAV photogrammetry was employed for the 3D modeling of a multi-story complex and circular building. Both oblique and nadir flight strategies were separately applied and evaluated during the UAV image capture process.

 Şehir, ticaret, sanayi ve altyapı hizmetlerinin yoğun olarak yer aldığı, yerleşim alanlarının insan, bina, altyapı gibi unsurları bünyesinde barındıran bir yerleşim birimidir. Bu unsurlardan biri olan binalar genellikle çatı, duvar ve zemin gibi yapısal özelliklere sahiptir. Binaların yaygınlığı, amacı ve tasarımı, bulundukları şehrin ekonomik ve sosyal yapısı hakkında bilgi verir; örneğin metropollerde kompleks binalar görülürken, kırsal alanlarda basit bina türleri görülmektedir. Tasarım ve inşaat açısından yapısal olarak zorlu olan kompleks binalar, görsel anlayışı geliştirmek, mekansal düzenlemeleri kolaylaştırmak ve mühendislere bina tasarımı üzerinde daha fazla kontrol sağlamak için 3 boyutlu olarak modellenmelidir. Projenin uygunluğuna göre kullanıcılar modelleme için dijital işleme, lazer tarama veya fotogrametri gibi yöntemleri tercih edebilirler. Fotogrametri, nesnelerin 3 boyutlu koordinatlarını ve şekillerini belirlemek için fotoğrafların analizini kullanan bir yöntemdir. Bu yöntem nesnelerin 3 boyutlu modellerinin oluşturulmasına olanak sağlar. Günümüz 3 boyutlu modelleme süreçlerinde fotogrametrinin alt alanı olan İnsansız Hava Aracı İHA fotogrametrisi sıklıkla tercih edilmektedir. İHA fotogrametrisi, insansız hava araçları kullanılarak görüntülerin toplanmasını içeren, hızlı ve uygun maliyetli bir yöntem olarak bilinmektedir. Bu çalışmada çok katlı, kompleks ve dairesel bir binanın 3 boyutlu modellenmesi için İHA fotogrametrisi kullanılmıştır. İHA görüntü yakalama sürecinde hem eğik hem de nadir uçuş stratejileri ayrı ayrı uygulanmış olup değerlendirilmiştir.
