Abstract

There are many applications on using AR in supporting manufacturing and related areas ranging from designing, simulation, testing, repairing, and maintenance. The objective of this research is to find the algorithm for measuring the size and find the shape of the room for facility management using marker-based AR technology. The applications program was designed and developed using the Unity 3D game engine and OpenCV library. It was designed to be used by many devices running on various operating systems such as Windows, OSX, iOS, and Android. Test of the concept was done in three situations, i.e., three rooms with different sizes. The first room is the smallest one with the size = 25.245 m³. The second room is the biggest one with the size of 117.35 m³ and the third one with the size = 56.1 m³. The results calculating from the distances of the markers show that the sizes of the space obtaining from the application are different from the manual measure less than 3%, which means that the system can provide high accuracy in measurement.
