4 and 5 are views for explaining a stereoscopic image display method using binocular parallax according to an embodiment of the present invention, Figure 4 is a method using a lenticular lens array (lenticular lens array) 5 shows a method of using a parallax barrier.

The binocular parallax refers to the difference in the way the left and right eyes of a person see things. When a human's brain synthesizes the image seen through the left eye and the image seen through the right eye, the synthesized image makes a person feel three-dimensional. In the following description, a phenomenon in which a person feels a stereoscopic sense according to binocular parallax is referred to as 'stereoscopic vision', and a three-dimensional image causing stereoscopic vision is referred to as a 'stereoscopic image'. Also, when a specific object included in the image causes stereoscopic vision, the object is referred to as a 'stereoscopic object'.

The stereoscopic image display method according to binocular disparity is classified into a glasses type that requires special glasses and a non-glass type that does not require glasses. The spectacle type is an anaglyph using a sunglasses with wavelength selectivity, a polarization filter using a shading effect according to a polarization difference, and a shutter glasses method to alternately present images of left and right within an afterimage of an eye. Glasses). In addition, there is a method in which a filter having different transmittances is mounted in the left and right sides to obtain a stereoscopic effect on the movement in the left and right directions according to the time difference of the visual system coming from the difference in the transmittances.

The autostereoscopic method, in which a stereoscopic effect is generated on the image display surface rather than the observer, includes a parallax barrier method, a lenticular lens method, a microlens array method, and the like.

Referring to FIG. 4, the display module 141 includes a lenticular lens array 11a to display a stereoscopic image. The lenticular lens array 11a includes a display surface 13 in which the pixels L to be input to the left eye 12a and the pixels R to be input to the right eye 12b are alternately arranged along the horizontal direction, and the left and right eyes 12a, 12b), and provides optical discrimination directivity for the pixel L to be input to the left eye 12a and the pixel R to be input to the right eye 12b. Accordingly, the image passing through the lenticular lens array 11a is observed separately from the left eye 12a and the right eye 12a, and the human brain is viewed through the left eye 12a and through the right eye 12b. By synthesizing the three-dimensional image.

Referring to FIG. 5, the display module 141 includes a parallax barrier 11b having a vertical grid shape to display a stereoscopic image. The parallax barrier 11b includes a display surface 13 and left and right eyes 12a in which pixels L to be input to the left eye 12a and pixels R to be input to the right eye 12b are alternately arranged along the horizontal direction. 12b), the image is separated from the left eye 12a and the right eye 12b through a vertical grid-shaped aperture. Therefore, the human brain synthesizes an image viewed through the left eye 12a and an image viewed through the right eye 12b to observe a stereoscopic image. The parallax barrier 11b is turned on only when a three-dimensional image is to be displayed and is separated from the incident time, and is turned off when a planar image is to be displayed. have. On the other hand, the above-described three-dimensional image display method for explaining the embodiment of the present invention, the present invention is not limited thereto. The present invention can display a stereoscopic image using binocular disparity using various methods in addition to the above-described method.

An embodiment disclosed in this document may be implemented in the electronic device 100 described with reference to FIGS. 1 to 3. Hereinafter, an operation of the electronic device 100 for implementing an embodiment disclosed in this document will be described in more detail.

The storage unit 150 may store a map model used for the navigation service and objects related to the navigation function.

In addition, the controller 170 may generate a navigation image for stereoscopic vision, and provide a navigation service to a user by using the navigation image. To this end, the controller 17 may obtain a map model corresponding to the location data of the vehicle and an object related to a navigation function from the storage 150, and generate a stereoscopic navigation image using the same. When rendering to generate a stereoscopic navigation image, the controller 170 may control a stereoscopic sense of distance of the stereoscopic navigation image based on at least one criterion. In addition, the controller 170 may control to display at least one object included in the stereoscopic navigation image in a non-stereoscopic manner. A rendering method for generating a stereoscopic navigation image will be described in detail with reference to FIGS. 6 to 9 to be described later.

Hereinafter, the navigation service method of the vehicle navigation apparatus 100 according to an embodiment of the present invention and the operation of the vehicle navigation apparatus 100 for implementing the same will be described in detail with reference to FIGS. 6 to 9.

6 is a flowchart illustrating a navigation service method of a vehicle navigation apparatus 100 according to an embodiment of the present invention.

Referring to FIG. 6, the controller 170 acquires location data through the location data module 111 as a navigation service provision request is received. Then, a stereoscopic navigation image is generated based on the acquired position data (S101). In addition, the navigation service is provided by displaying the generated stereoscopic navigation image through the display module 141 (S102). Here, the navigation image may include a map model. In addition, the map model may include objects modeled on actual roads, facilities, traffic lights, buildings, etc. to display road information. In addition, the navigation image may include a plurality of objects related to the navigation function. Here, the objects related to the navigation function may include an object for displaying navigation information and an object for controlling the vehicle navigation apparatus 100. Navigation information displayed using the object may include a moving path to a destination of the vehicle, a moving speed of the vehicle, and a point of interest (POI). Each object included in the navigation image is stored in the storage unit 150, and the controller 170 reads necessary objects such as a map model from the storage unit 150 based on the position data obtained through the position data module 111. And create navigation images.

7 illustrates an example of a stereoscopic navigation image generated by the vehicle navigation apparatus 100 according to an embodiment of the present invention. Referring to FIG. 7, the stereoscopic navigation image 7 includes a left image 7a and a right image 7b. The controller 170 synthesizes or displays the left image 7a and the right image 7b alternately or sequentially to provide a 3D navigation image according to binocular disparity to the user.

The controller 170 may separately control a sense of distance according to stereoscopic vision of each object included in the 3D navigation image when the 3D navigation image is generated. The controller 170 controls a sense of distance according to stereoscopic vision of each stereoscopic object by using the parallax of the left image and the right image included in the 3D navigation image. That is, it is possible to control the sense of distance according to stereoscopic vision of each stereoscopic object by controlling the position where the corresponding object is displayed in the left image and the right image, or by controlling the combined position of the left image and the right image. In addition, according to an embodiment of the present disclosure, the controller 170 may control a depth according to stereoscopic vision of at least one object included in the navigation image, based on at least one criterion. Accordingly, even in the objects included in the same navigation image, a sense of distance according to stereoscopic vision may be displayed differently.

First, the controller 170 may control the distance feeling according to stereoscopic view of each object based on a preset priority. For example, the controller 170 sets an object having a priority such as a traffic light, POI, etc. included in the map model to have a higher priority than other objects, and accordingly stereoscopic view of the corresponding objects so that they appear more protruding than other objects. You can also control the sense of distance. The priority of each object can be set by the user.

In addition, the controller 170 may set a sense of distance according to stereoscopic view of the navigation image according to a view mode. In this case, as the sense of distance of the navigation image changes according to the view mode, the sense of distance of each object included in the navigation image also changes. The view mode is classified according to the viewpoint position, the line of sight direction, and the like of the corresponding driver, and the position of the driver's viewpoint for determining the sense of distance of the map model or the navigation image varies according to the view mode. Therefore, the controller 170 may control the sense of distance according to the stereoscopic view of the navigation image to express the corresponding sense of distance according to the view mode of the navigation image.

In addition, the controller 170 may display some objects among the objects included in the navigation image as two-dimensional objects. For example, the controller 170 may display at least one object for receiving a control input as a 2D object. At least one object for receiving the control input may include a button, an icon, a selection indicator, and the like. When all the objects included in the navigation image are displayed as 3D stereoscopic objects, the actual display position where the object is actually displayed on the display area and the virtual display position where the user feels that the object is displayed due to stereoscopic vision may be different. Accordingly, when the user needs to input a control input by touching the display area, it may be difficult to accurately touch the position where the corresponding object is actually displayed. On the other hand, when the object is displayed as a two-dimensional object, the actual display position where the object is displayed in the display area and the virtual display position where the user feels that the object is displayed due to stereoscopic vision are the same. Therefore, when displaying the object for receiving the control input as a two-dimensional object, it is possible to solve the above-described difficulty of accurate operation.

In addition, the controller 170 may display only some of the objects included in the navigation image as a 3D stereoscopic object. For example, the controller 170 may display only an object corresponding to important information in the navigation image as a 3D stereoscopic object. In this case, the remaining objects such as the map model may be displayed in two dimensions. Accordingly, the vehicle navigation apparatus 100 can effectively convey important information to the user by highlighting and displaying important information as a three-dimensional solid object.

As described above, when only some of the objects included in the navigation image are displayed as 2D objects or 3D stereoscopic objects, the objects displayed in 2D or the objects displayed in 3D may be selected by the user. . In this case, the user may be set to display a three-dimensional solid object for an object determined to be important or to display a two-dimensional object for an object receiving a control input. Therefore, a customized stereoscopic image may be provided to the user.

Meanwhile, as described above, when the navigation image includes both the 2D object and the 3D object, the controller 170 may generate the navigation image in various ways.

For example, the controller 170 controls the distance of each object included in the navigation image when converting the two-dimensional navigation image into a three-dimensional navigation image, thereby navigating the navigation image including both the two-dimensional object and the three-dimensional object. Can be generated.

8 illustrates an example of generating a navigation image including both a 2D object and a 3D object. Referring to FIG. 8, the controller 170 generates a 3D navigation image by rendering a 2D navigation image. That is, a left image and a right image to be used for displaying a 3D navigation image are generated from the 2D navigation image. At this time, the controller 170 controls the position of each object in the left image and the right image so that a sense of distance according to stereoscopic vision corresponding to each object is displayed.

Also, for example, the control unit 170 converts an object to be displayed in 3D into a 3D object separately, and then synthesizes the object to be displayed in 2D, thereby navigating the image including both the 2D object and the 3D object. You can also create

9 illustrates another example of generating a navigation image including both a 2D object and a 3D object. Referring to FIG. 9, the controller 170 divides the objects included in the navigation into at least one first object 9a to be displayed in three dimensions and at least one second object 9b to be displayed in two dimensions. The at least one first object 9a to be displayed in three dimensions is separately rendered to generate the three-dimensional solid object 9c. That is, a left image and a right image on which the three-dimensional solid object 9c is displayed are generated. Subsequently, the controller 170 combines the at least one second object 9b displayed in two dimensions to the left image and the right image in which the three-dimensional stereoscopic object 9c is displayed, and finally, the stereoscopic navigation image 9d. Create
