Research on layout optimization and positioning of LED light source based on visible light communication

At present, the research on the light source layout of the indoor visible light communication positioning system mainly focuses on how to improve the indoor positioning accuracy, while ignoring the uniformity of indoor light. In view of this problem, this paper proposes a honeycomb light source layout model based on equilateral triangles, constructs and evaluates the adaptability function related to illuminance uniformity and positioning error, and uses the multi-objective evolution algorithm based on decomposition to optimize the position coordinate information of the LED light source, so as to improve the indoor light uniformity and meet the indoor positioning accuracy on the basis of meeting the indoor lighting standards.
