Several indoor positioning systems have been studied to offer a public service based on one's location information. We have studied an indoor localization system using original fiducial markers. The original markers can be designed freely by users; therefore, they can be used for interior decoration. Using this system, you can obtain the three-dimensional position and pose of your camera by capturing the image of the markers arranged on the floor. However, there are some problems associated with the use of this system in a public space, such as a decline in the marker recognition rate by a change in the surrounding light condition and an instability in the marker recognition rate depending on the type of marker used and the camera angle. In this study, we enhanced the robustness of an indoor localization system used in a public space and increased the number of recognizable markers.
