Description
In this paper, we propose a distance-illuminance model for lighting devices. We also propose an indoor localization method utilizing the model and trilateration. In our previous study, we proposed an indoor localization method based on illuminance fingerprinting. This previous method, however, takes a non-negligible human labor to construct multiple distance-illuminance models for different lighting devices since it supposes to use all existing lighting devices installed in the target indoor space and to be able to control these devices via home network. To cope with these problems, our method proposed in this paper estimates distances from three newly installed controllable lighting devices based on the illuminance at the target point by alternately turning on each of the devices. Then, the proposed method estimates the position of the target point based on trilateration. Merits of the proposed method are two folds. First, it requires only one distance-illuminance model since we newly install three identical lighting devices. Second, it does not need to consider influences by external lighting devices (or sunlight) since the proposed method measures the difference of the illuminance between before and after turning on a lighting device. We conducted experiments in a room in an ordinary home and confirmed that the proposed method could estimate the position of the illuminance sensor within 0.3m error on average.
