Abstract：In order to improve the limitations of radio wave positioning, this article highlights a visible light positioning algorithm based on the angle of arrival, which perceives the arrival angle of incoming light by combining the angle tilt of the detector with the positioning algorithm. Design the optimal shape of the receiver array through simulation experiments. By setting the positions of multiple light sources and combining them with angle intersection algorithm, the specific coordinates of the target can be located. Experimental tests have shown that the error of arrival angle prediction can be kept within 3 when the distance from the target is 3 to 12 meters. When using indoor positioning results for angle intersection, the Euclidean distance error of positioning coordinates can be kept within 0.8 m.
