Abstract:
In recent years, there has been a growing interest in indoor positioning techniques using the ubiquitous infrastructure. This paper describes an indoor positioning method using light-emitting diode light reflecting from the floor and a smartphone camera recording it. Almost all traditional methods must detect the light source directly. However, there are some constraints to their usage since light sources cannot always be detected directly. Our proposal aims to solve this problem by estimating the position of a camera that does not face the light directly but records light reflected from the floor. The camera need not detect the ceiling lights directly from an image, unlike existing methods. Experimental results show that the proposal requires less than 1/100 the number of pixels for localization as do existing methods, and the 3-D position and attitude can be estimated within 0.27 m and 5.78 degrees at the 90th percentile in a 4.0 m square room.
