System capable of providing virtual three-dimensional image for traffic safety, device capable of outputting virtual three-dimensional image for traffic safety, and method of providing virtual three-dimensional image for traffic safety
PURPOSE: A virtual 3D image providing system for traffic safety, a virtual 3D image outputting device for traffic safety and a virtual 3D image providing method for traffic safety are provided to offer a 3D image for traffic safety to pedestrians or vehicles by generating the virtual 3D image for traffic safety. CONSTITUTION: A virtual 3D image providing system for traffic safety includes a virtual 3D image outputting device(200) and a central control device(100). The central control device controls the virtual 3D image outputting device to output a virtual 3D image for traffic safety. The virtual 3D image for traffic safety corresponds to a traffic light control signal. The traffic light control signal is generated from a traffic signal controller(400). The virtual 3D image outputting device includes a power line communication modem(220) and a hologram image generator(240). The power line communication modem receives the traffic light control signal. The hologram image generator outputs a hologram image. [Reference numerals] (100) Central control device; (120) Controller; (140,220) Power line communication modem; (200) Virtual 3D image outputting device; (240) Hologram image generator; (300) Power line; (400) Traffic signal controller
