POSITIONING DEVICE POSITIONING SYSTEM USING OPTICAL SIGNAL AND METHOD THEREOF

摘要

The present invention relates to a position measuring apparatus, a positioning system and a positioning method thereof. More particularly, the present invention relates to a positioning system for positioning the position of an object using an optical signal and a method of positioning the same. The positioning system according to the present invention includes first and second diffusing light sources, wherein the first and second diffusing light sources each include a light source section for emitting an optical signal including its own unique position information in all directions, Wherein the position measuring apparatus includes a sensor unit for receiving the optical signal and an operation unit for determining the position in response to the received optical signal, The first and second photosensors sense the optical signal in the first and second imaging regions corresponding to the first and second optical sensors, respectively, and provide the sensed optical signals to the operation unit. According to the positioning system using the optical signal and the positioning method using the optical signal according to the present invention, it is possible to perform positioning at the same level in all environments without being influenced by the terrain, and even when positioning a vertical unit as well as a horizontal unit, And can provide stable positioning results without being affected by frequency disturbance.
