摘要
A method for judging rotating characteristics of light sources based on summation calculation in visible light indoor positioning is disclosed. The method is implemented based on an LED positioning system, and comprises the following steps: firstly, arranging the light sources into a convex pattern in order, and arranging the emitted sequence for each light source according to set conditions; secondly, fixing the position and attitude of a cell phone as a receiving end, continuously shooting with the cell phone camera to obtain a set of light source pictures, and performing image processing to obtain emitted sequences of the light sources; thirdly, performing sequence correlation operation on adjacent light sources to obtain emitted sequence delays, and performing summation calculation on the emitted sequence delays, to judge true and false light sources; and finally, excluding the false light source, and then completing positioning using a positioning algorithm.
