Surabaya Heroes Monument Topographic Data Acquisition Using Quad-Rotor Unmanned Aerial Vehicle (UAV)

The acquisition of 2D images of the Heroes Monument of Surabaya is a challenging task for the image-based modelling due its historical architecture complexity and structural delicacy. An effective approach of 2D acquisition is using multiple circular orbital with Unmanned Aerial Vehicle (VAV). Therefore, a quadcopter non fixed wing equipped with Global Positioning Satellite (GPS), mounted camera, and flight planning using circular orbits are the main key to take the 2D images steadily. Moreover, a field survey of preparation and observation area surroundings object is conducted to plan the part of the object that need to acquire with some details. UAV requires a plain sight to take off and frees from any obstacle which is able to interrupt UAV navigation. Thus, there are 4 phases to acquire 2D images, on every phase, they need one circle to finish and move them to other phases. While UAV loitering circle the object, the pilot manually took the 2D image. As a result, along with 80%, the overlapping of 2D images and more than 150 images have been collected, they are possible to be modeled into 3D.
