ROUTE GUIDANCE DEVICE AND ROUTE GUIDANCE SYSTEM BASED ON AUGMENTED REALITY AND MIXED REALITY

The present invention relates to a route guidance device comprising: a communication unit for communicating with a cloud server; an interface unit for receiving sensing information obtained by sensing a driving state of a vehicle and an image of a surrounding environment of the vehicle, which includes a road image; an AR module for rendering AR information by using sensing information and POI information received from the cloud server; an MR module for rendering MR information including a virtual object on the basis of sensing information and map information received from the cloud server; and a processor for controlling the interface unit to cause displaying, on the display unit, of an AR view image including AR information or an MR view image including MR information, detecting a view image matching a driving situation of the vehicle on the basis of sensing information in a state where a first view image among the AR view image and the MR view image is displayed, and controlling the display unit of the vehicle to switch the view image to a second view image differing from the first view image if the detected view image is different from the first view image.
