India is a country rich in regionally diversified cultural heritage monuments and ranked as sixth in number according to UNESCO cultural heritage sites. Heritage monument site is a location where there is importance in terms of social history that is preserved based upon its rich cultural values. Warangal is one of the Indian cities rich in heritage monuments. It is also included in the country’s prestigious project HCDAY (Heritage City Development and Augmentation Yojana) monuments for restoration and preservation. Kota Gullu comprises about 20 temples, and all of them are different in design and size that portray architectural values that take back us to the twelfth century. UAV is used in acquiring aerial photography and collection of monuments imaging data. With the advancements of UAV, high-resolution images are acquired in stipulated time. The sophisticated techniques in photogrammetry also play a crucial role in utilizing photographs for generating relatively accurate 3D models. Kota Gullu structure is chosen in the preservation of the 3D model. Pix4Dcapture is a mobile-based application used for acquiring the images of the temple ruins in the study area. The processing of the images to 3D models is done by using Pix4Dmapper Desktop software. This case study develops a 3D model which can be used for preservation of the heritage monument.

印度是一个拥有丰富多样的地区性文化遗产的国家，根据联合国教科文组织的文化遗产排名，印度位列第六。文化遗产古迹是根据其丰富的文化价值保存的对社会历史具有重要意义的地点。瓦兰加尔（Warangal）是印度历史遗迹丰富的城市之一。它也被包含在该国著名的HCDAY（遗产城市发展与扩建Yojana）古迹中，以进行修复和保护。哥打古鲁（Kota Gullu）约有20座庙宇，所有庙宇的设计和大小都各不相同，描绘出的建筑价值将我们带回了十二世纪。无人机用于获取航空摄影和收集古迹成像数据。随着无人机的发展，可以在规定的时间内获取高分辨率的图像。摄影测量学中的先进技术在利用照片生成相对准确的3D模型方面也起着至关重要的作用。在保留3D模型时选择了Kota Gullu结构。Pix4Dcapture是基于移动的应用程序，用于获取研究区域中庙宇遗址的图像。通过使用Pix4Dmapper Desktop软件将图像处理为3D模型。本案例研究开发了3D模型，可用于保护历史古迹。通过使用Pix4Dmapper Desktop软件将图像处理为3D模型。本案例研究开发了3D模型，可用于保护历史古迹。通过使用Pix4Dmapper Desktop软件将图像处理为3D模型。本案例研究开发了3D模型，可用于保护历史古迹。
