Route guidance device and route guidance system based on augmented reality and mixed reality
The present invention provides a route guidance device and a route guidance system. The route guidance device according to an embodiment of the present invention comprises: a communication part that communicates with a cloud server; an interface part that receives, from at least one sensor provided in a vehicle, a camera image including an image of a road on which the vehicle is traveling, and sensing information obtained by sensing a driving state of the vehicle; an MR module that renders MR information including at least one virtual object on the basis of the camera image, the sensing information, and map information received from the cloud server; and a processor that controls the interface part such that an MR view image including the MR information is displayed on a display part of the vehicle, wherein the processor, when a preset condition is satisfied, changes the MR view image to display a scene corresponding to a place at which the vehicle is to travel.
1 . A route guidance device comprising:
a communication unit that communicates with a cloud server;
an interface unit that receives, from at least one sensor disposed in a vehicle, a camera image including an image of a road on which the vehicle is traveling, and sensing information obtained by sensing a traveling state of the vehicle;
a mixed reality (MR) module that renders MR information including at least one virtual object, based on the camera image, the sensing information, and map information received from the cloud server; and
a processor that controls the interface unit so that an MR view image including the MR information is displayed on a display of the vehicle,
wherein the processor converts the MR view image to display a scene corresponding to a place where the vehicle is to travel when a preset condition is satisfied, and
wherein the preset condition includes at least one of a case where the vehicle stops for a predetermined time, a case where the vehicle enters within a predetermined distance from a destination, a case where the vehicle enters within a predetermined distance from an intersection, and a case where a point of interest (POI) object displayed on the MR view image is selected.
2 . The route guidance device of claim 1 , wherein the processor displays route information for guiding a route, along which the vehicle is to travel up to a destination, on the MR view image, and
controls the MR view image to display a scene of a place ahead of a current location of the vehicle according to the route information, on a basis of satisfaction of the preset condition.
3 . The route guidance device of claim 1 , wherein an icon for representing the scene corresponding to the place where the vehicle is to travel is displayed on the MR view image, and
the preset condition includes that the icon is selected by a user.
4 . The route guidance device of claim 1 , wherein the MR view image is a scene looking at a digital-twin map, to which a current situation is reflected in real time, at one point at a predetermined viewing angle.
5 . The route guidance device of claim 4 , wherein the processor outputs an MR view image reflecting the current situation in real time on the display of the vehicle when the scene corresponding to the place where the vehicle is to travel is displayed.
6 . The route guidance device of claim 1 , wherein the processor outputs the MR view image to correspond to a scene ahead of the vehicle based on a vehicle object indicating a current location of the vehicle.
7 . The route guidance device of claim 6 , wherein the processor generates a ghost car that runs ahead of the vehicle object along a route, on which the vehicle is to travel, based on satisfaction of the preset condition, and converts the MR view image to display a scene ahead of the ghost car based on the ghost car.
8 . The route guidance device of claim 1 , wherein the MR view image converted based on satisfaction of the preset condition is a predicted view image that shows a situation ahead along a route, on which the vehicle is to travel, on a digital twin map in advance.
9 . The route guidance device of claim 1 , wherein the processor displays in advance the scene corresponding to the place where the vehicle is to travel by varying an altitude of a point looking at a digital-twin map when the MR view image is converted based on satisfaction of the preset condition.
10 . The route guidance device of claim 1 , wherein the processor controls the interface unit to output, on the display of the vehicle, a first MR view image, which displays a scene ahead of the vehicle, and a second MR view image, which displays the scene corresponding to the place where the vehicle is to travel, based on a current location of the vehicle, when the preset condition is satisfied.
11 . The route guidance device of claim 10 , wherein the processor outputs the second MR view image in a form of a pop-up window.
12 . The route guidance device of claim 10 , wherein the processor splits a screen of the display of the vehicle into a first area and a second area when the preset condition is satisfied, and
controls the interface unit to output the first MR view image in the first area of the display, and output the second MR view image in the second area.
13 . The route guidance device of claim 10 , wherein the second MR view image is an image playing a scene that the vehicle is to move by a predetermined distance along a route for the vehicle to travel from a scene, which the vehicle is viewing at the current location.
14 . The route guidance device of claim 10 , wherein the processor outputs the second MR view image outputting a scene that the vehicle is to move by a predetermined distance along a route for the vehicle to travel, and then controls the second MR view image to disappear when the vehicle moves by the predetermined distance.
15 . The route guidance device of claim 10 , wherein the processor splits a screen of the display of the vehicle into a first area and a second area in response to the preset condition being satisfied, and controls the interface unit to output the first MR view image in the first area of the display, and output the second MR view image in the second area.
16 . The route guidance device of claim 10 , wherein the processor outputs the second MR view image outputting a scene that the vehicle is to move by a predetermined distance along a route for the vehicle to travel, and then controls the second MR view image to disappear in response to the vehicle being moved by the predetermined distance.
17 . The route guidance device of claim 1 , wherein the processor controls the interface unit to output, on the display of the vehicle, a first MR view image, which displays a scene ahead of the vehicle, and a second MR view image, which displays the scene corresponding to the place where the vehicle is to travel, based on a current location of the vehicle, in response to the preset condition being satisfied.
18 . The route guidance device of claim 1 , wherein the preset condition includes the case where POI object displayed on the MR view image is selected.
