1. An apparatus based on wireless optical communication, comprising:
a light source outputting light;
an optical circulator outputting the light in at least one direction;
a collimator converting and outputting the light output through the optical circulator into a parallel beam;
an optical regulator reflecting the light converted into the parallel beam, and transferring the reflected light to an external apparatus, and receiving the reflected light from the external apparatus, the reflected light being light output by reversely reflecting the light by the external apparatus;
an optical detector converting the reflected light into an electric signal; and
a controller analyzing the electric signal and acquiring an intensity of the reflected light, and calculating central coordinate information of the external apparatus based on the intensity value of the reflected light,
wherein the central coordinate information is expressed as a pole coordinate including length information and angle information,
wherein the controller determines the length information and the angle information included in the central coordinate information based on intensity values of a plurality of reflected light acquired by changing a reaching point of the light by controlling the optical regulator, and
wherein the controller
determines area information based on information on a position where the external apparatus is present,
changes the reaching point of the light by controlling the optical regulator based on the area information,
acquires intensity values of a plurality of first reflected light in each of a plurality of first points in conjunction with changing the reaching point of the light, and
determines, as the angle information, first angle coordinate information of a point having a largest intensity value among the intensity values of the plurality of first reflected light.
