Abstract:

In order to improve the estimation accuracy of radio propagation simulation using a 3D model reconstructed by depth sensors, recovering missing regions of the 3D model is important. In this paper, we report an evaluation result of indoor radio estimation accuracy by using such a completed 3D model. We first describe the evaluation scene and the measurement method of radio powers we used for experiments. We then give an overview of the method for reconstructing and completing a 3D model of the evaluation scene. Finally, we compare simulation results obtained with the original model and the completed model against the real measurements. The errors obtained with the original and completed model were 2.40 dB and 2.16 dB respectively, demonstrating the effectiveness of the 3D model completion for the indoor radio estimation.
