Comparative Flight Direction Methods of Photogrammetry in Unmanned Aerial Vehicle (UAV) Technology

Abstract

Indonesia is an archipelago country which has varieties of cultural heritage, both ancestral heritage and the remnants from the Dutch colonial period. Quantity, variations and locations scattered throughout Indonesia are the problem in making documentation. Photogrammetry is considered suitable for documenting cultural heritage buildings because it focuses on the methods and devices used as an important key to getting good data so that it can be processed. Villa Isola is one of the heritage buildings of the Dutch colonial government which was chosen as the research object because it has an irregular and dynamic shape. This paper studies the method of taking the visual data photogrammetry of a building as well as the landscape around it with 45 degree and 90 degree angle flight directions. The results of the study found that the comparison of the results of the processing of the two UAV flying methods above provided more important information. Furthermore, the picture of the number of clouds and meetings at a 45 degrees flying angle is more accurate than 90 degrees flying angle. Due to shorter duration data processing and lower memory consumption of devices of 45 degrees flying angle of devices.
