Embodiment
[0070] In this system, the LED in the indoor space transmits the optical signal through the indoor space channel, and the receiving end uses the PD detector to convert the obtained optical signal into an electrical signal for positioning. The overall structure of the technical solution of the present invention is as follows: figure 1 shown.
[0071] In the present invention, firstly, the indoor ceiling is evenly divided to form a 4*3 grid, and an LED light group is placed in each grid, and each LED light group consists of 7*7 LEDs to form a rectangular array, such as figure 1 shown. Due to the multipath effect and noise interference when the light source propagates. Therefore, the present invention optimizes the LED light intensity to make the received light power uniform, ensure that the communication power and lighting distribution of each position in the room are almost the same, and improve the indoor positioning accuracy.
[0072] The invention optimizes the light inte...
