Abstract

The invention provides a high-reliability lamp mutual positioning method, system and device and a medium. The method comprises the following steps: determining a mutual influence relationship between lamps through reference parameters of the lamps with a visible light communication function in a target shopping mall during installation and working state parameters of visible light signals of the lamps; determining an interference feature vector of each lamp in the positioning process according to the mutual influence relationship, the multipath effect of the visible light signal and the interference superposition feature; determining a positioning constraint condition of each lamp, and determining a cooperative positioning parameter of each lamp through all the positioning constraint conditions and all the interference feature vectors; and determining relative positioning information of each lamp in the target shopping mall according to the anti-interference configuration parameter of the visible light signal of each lamp in the positioning process and all the cooperative positioning parameters. By adopting the scheme of the invention, the influence of the multipath effect and signal attenuation between the lamps on mutual positioning of the lamps can be reduced, so that high-reliability mutual positioning of the lamps is realized.
