Description

3D control system specialized in navigation system and its method

The present invention relates to a navigation system for providing a map service, and more particularly, to a three-dimensional control system and a method for easily manipulating a map screen provided by a navigation system.

In general, a navigation system is a system that provides information for driving a moving object such as a vehicle by using a satellite for user's convenience and safe operation.

The navigation system may include a global positioning system (GPS) module to receive predetermined positioning information from a GPS satellite floating on the earth and calculate a position of the moving object based on the positioning information.

The navigation system may provide not only a map image of a location desired by the user, but also a map image obtained by map-matching the current location of the moving object to previously stored map data.

Recently, as the performance of the hardware is improved and advanced, map services of various environments are required, and the three-dimensional map image is combined with the current position of the moving object to have a virtual three-dimensional effect such as a bird's eye view. Displaying three-dimensional navigation system has emerged.

In a conventional two-dimensional navigation system, a map screen can be sufficiently manipulated through a touch screen using two-dimensional coordinates.

On the other hand, since the three-dimensional navigation system requires six-axis manipulation for panning and heading up, the two-dimensional touch screen alone cannot satisfy the user's demand for the controller of the map screen. Therefore, research and development of a controller that can more easily and intuitively control a map screen provided by a 3D navigation system is required.

The present invention provides a three-dimensional control system and method that can more conveniently manipulate the movement and rotation of the map screen in the map service for the purpose of route guidance.

Three-dimensional control system of the navigation system according to an embodiment of the present invention includes a map providing device for providing a map screen; And a control device for controlling the heading up or panning of the map screen based on the 3D motion of the user.

In the three-dimensional control method of the navigation system according to an embodiment of the present invention, the three-dimensional control method of the navigation system consisting of a map providing device and a control device, comprising: providing a map screen in the map providing device; And controlling, by the control device, the rotation or movement of the map screen based on a three-dimensional motion of the user.

According to the present invention, by providing a control environment capable of six-axis operation for the movement and rotation of the map screen, it is possible to implement a controller specialized for three-dimensional navigation and to improve user convenience for the manipulation of the map screen.

Hereinafter, with reference to the accompanying drawings will be described in detail the three-dimensional control system and method of the navigation system according to the present invention.

The present invention relates to a navigation system that provides a map screen in the form of a virtual three-dimensional space, and provides a dedicated controller of a three-dimensional navigation system that can more easily manipulate the heading up and panning of the map screen. It is to provide.

The 3D control system of the present invention may include a control device 110 and a map providing device 120.

The map providing device 120 provides a map screen and performs rotation and movement of the map screen under the control of the control device 110, and the control device 110 performs a three-dimensional operation of a user. On the basis of this serves to control the rotation and movement of the map screen provided by the map providing device 120.

Here, the rotation mode is a mode for changing the view point of the map screen, and the movement mode is a mode for changing the display center point of the map screen. The movement mode may include an up and down movement mode for moving the map screen up and down, a left and right movement mode for moving left and right, and a forward and backward movement mode for moving forward and backward.

The control device 110 may include a motion detection unit 111, a mode switching unit 112, a control unit 113, and a first communication module 114.

The control device 110 may refer to a user input means connected to the map providing device 120 by wire or wirelessly to perform a role as a kind of remote controller, and the map providing device 120 And the case (separate) is configured to be able to control the map providing apparatus 120 from the outside.

When the user performs the operation of rotating or moving the hand while holding the control device 110 in the hand, the control device 110 may sense the motion of the user in three dimensions.

The motion detection unit 111 is used to rotate the yaw, pitch, and roll of the X, Y, and Z axes in order to detect a 3D motion of the user. Accordingly, a three-dimensional acceleration sensor that outputs yaw, pitch, and rotation angle components of the roll can be used.

As shown in the figure, the three-dimensional operation performed in a state where the user possesses the control device 110 includes yaw rotation 201, pitch rotation 202, and roll which rotate about each axis of the X, Y, and Z axes. Corresponds to the rotation 203 and the up / down movement 206, the left / right movement 204, and the front / rear movement 205 for moving each axis in the direction. The control device 110 may control the rotation or movement of the map screen based on the three-dimensional operation.

In general, since the navigation system is used in the moving object, it is difficult to determine the movement operation with respect to the X-axis, the Y-axis, and the Z-axis when the moving object is driven, so that the control device 110 is in the X-axis, Y-axis, and Z-axis directions. Each of the three rotational motions may be controlled by mapping the three rotational motions. In other words, the three-dimensional control system of the present invention may control the yaw, pitch, and roll rotation by applying one-to-one with each movement operation for the vertical movement mode, the horizontal movement mode, and the horizontal movement mode.

In order to control the rotation mode and the movement mode only by the rotation operation about the X axis, the Y axis, and the Z axis, a mode switching function capable of switching between the rotation mode and the movement mode is required.

To this end, the mode switching unit 112 serves as a switch for switching to one of the rotation mode and the movement mode, it is configured to enable the selection and switching of the mode using one or two buttons. Can be.

The control unit 113 provides the map with control information for the rotation or movement of the map screen according to the 3D motion detected by the motion detection unit 111 in response to the mode selected by the mode switching unit 112. Output to device 120.

The controller 113 may output the rotation angle of the yaw, pitch, and roll output from the motion detection unit 111 as the control information in the rotation mode.

Meanwhile, in the movement mode, the control unit 113 adjusts the rotation angles of the yaw, pitch, and roll according to one-to-one mapped rotational operations (yaw, pitch, and roll) with respect to the vertical movement mode, the horizontal movement mode, and the front and rear movement modes. The control information may be output as control information for vertical movement, horizontal movement, and forward and backward movement, respectively, or only the rotation angle corresponding to the maximum angle among the rotation angles of the yaw, pitch, and roll may be output as the control information.

The control information output from the control unit 113 includes mode information (rotation mode, movement mode) selected by the user, and rotation angle information (yaw rotation angle component, pitch rotation angle component, roll rotation angle according to the user's three-dimensional motion). Information).

The first communication module 114 may perform data communication with the map providing apparatus 120 by a wired or wireless communication method. In the case of the wireless communication method, the first communication module 114 may use a Bluetooth communication method, an infrared communication method, a radio frequency (RF) communication method, or the like.

The first communication module 114 may transmit the control information to the map providing apparatus 120 under the control of the controller 113.

The map providing apparatus 120 may include a second communication module 121, a system controller 122, and a display unit 123.

The display unit 123 may serve to display the map screen, and the second communication module 121 may serve to receive control information transmitted from the control device 110.

In the rotation mode, the system control unit 122 may execute the rotation mode by changing a map view point of the map screen according to the received control information, that is, the yaw, pitch, and rotation angle of the roll.

The system controller 122 shares the rotational motion (yaw, pitch, roll) information mapped to the vertical movement mode, the horizontal movement mode, and the front and rear movement modes, respectively, and corresponds to the received control information in the movement mode. The display center of the map screen can be changed up / down and / or left / right and / or before / after. For example, when a pitch rotation angle is received from the control device 110 in a state in which a pitch operation using the control device 110 is mapped with a vertical movement mode, the system controller 122 is configured to perform the pitch operation. The display center of the map screen may be changed in the up / down direction according to the mapped up / down movement mode.

Furthermore, the control device 110 may be designed to be detachable from the map providing device 120. According to such a configuration, when the manipulation of the map screen is required, the control apparatus 110 is separated and used, and the control apparatus 110 is usually attached to the map providing apparatus 120 in the state where the control apparatus 110 is attached. The three-dimensional acceleration sensor configured in the control device 110 may be used for the purpose of detecting the traveling speed, the traveling direction, and the like of the moving object.

Hereinafter, the three-dimensional control method of the navigation system of the present invention described above.

In step S310, the three-dimensional control system detects a three-dimensional motion of the user and outputs control information for controlling the rotation and movement of the map screen based on the three-dimensional motion. This step (S310) is a process made in the control device 110 of the above configuration, the user controls the rotation and movement of the map screen provided by the map providing device 120 using the control device 110. can do.

In detail, in step S311, the 3D control system switches to the rotation mode or the movement mode according to the user's selection. When the map viewpoint of the map screen is to be changed, it may be switched to the rotation mode, and when the display point of the map screen is to be changed, it may be switched to the movement mode.

In operation S312, the three-dimensional control system may output control information for rotating or moving the map screen according to the user's three-dimensional operation in response to the mode switched in operation S311. When the user selects the rotation mode or the movement mode through the control device 110 and rotates the hand while holding the control device 110 in the hand, the control device 110 performs the rotation operation of the user. It may detect and output control information according to a corresponding mode with respect to the detected rotation operation.

The control device 110 outputs yaw, pitch, and rotation angle information about the X, Y, and Z axes according to the rotational motion of the user. May be output as control information for rotating the map screen.

On the other hand, since the movement mode is made up of the vertical movement mode, left and right movement mode, the front and rear movement mode, the three-dimensional control system is to rotate the user's rotation operation corresponding to the yaw, pitch, roll, the vertical movement mode, the left and right movement mode, One to one mapping can be applied to each movement operation for the forward and backward movement modes. In this case, the control device 110 adjusts the rotation angle of the yaw, pitch, and roll according to one-to-one mapped rotational motion (yaw, pitch, roll) with respect to the vertical movement mode, the horizontal movement mode, and the front and rear movement modes in the movement mode. The control information may be output as control information for vertical movement, horizontal movement, and forward and backward movement, respectively, or only the rotation angle corresponding to the maximum angle among the rotation angles of the yaw, pitch, and roll may be output as the control information. That is, the control device 110 performs the movement of the map screen in all directions up / down, left / right, and front / rear with respect to the movement mode, or maximum of up / down, left / right, and front / rear directions. The map screen may be moved in a direction having a rotation operation.

The control information output from the control device 110 is a user-selected mode (rotation mode, movement) together with rotation angle information (yaw rotation angle component, pitch rotation angle component, roll rotation angle information) according to the user's rotation operation Mode) information.

In operation S320, the 3D control system may receive the control information output in operation S310 and execute rotation or movement of the map screen according to the received control information. This step (S320) is a process made in the map providing apparatus 120 of the above configuration, it is possible to rotate or move the map screen in three dimensions under the control of the control device 110.

The map providing apparatus 120 may determine the rotation mode or the movement mode from the control information output from the control device 110 and determine the rotation angle information according to the rotation operation of the user. In addition, the map providing apparatus 120 may share the rotation operation (yaw, pitch, roll) information mapped to the vertical movement mode, the left and right movement mode, and the front and rear movement modes, respectively.

4 is a view for explaining a process of executing the rotation of the map screen, Figures 5 and 6 are views for explaining a process of executing the movement (up, down, left, right, front and rear) of the map screen.

In the rotation mode, the map providing apparatus 120 rotates the map screen 401 by changing the map view point 403 according to the rotation angle of the yaw, pitch, and roll as the control information. Can be performed. That is, the rotation mode may be performed by mapping the map view point 403 of the map screen 401 with the rotation angle directions of the yaw, pitch, and roll output from the control device 110.

On the other hand, the map providing apparatus 120 in the moving mode in the up / down and / or left / right and / or forward / rearward direction of the display center of the map screen according to the rotation angle of the yaw, pitch, roll which is the control information I can move it. That is, the movement mode with respect to the map screen may be performed according to the one-to-one mapped rotation operation (yaw, pitch, roll) with respect to the vertical movement mode, the left and right movement modes, and the forward and backward movement modes.

For example, when the rotation operation of the roll is a movement operation for the forward and backward movement mode, and the rotation operation of the yaw is mapped to the movement operation for the left and right movement mode, it is received from the control apparatus 110 as shown in FIG. 5. The display center point of the map screen 501 is moved forward / backward 503 according to the rotation angle of the roll among the rotated angle information, and the display center point of the map screen 501 is left / right according to the rotation angle of the yaw. May move in direction 505.

In addition, when the rotation operation of the pitch is mapped to the movement operation for the vertical movement mode, as illustrated in FIG. 6, the map screen 601 according to the rotation angle of the pitch among the rotation angle information received from the control device 110. ) Can be moved in the up / down direction 603.

Therefore, the three-dimensional control system of the present invention can easily manipulate the three-dimensional rotation and movement of the map screen according to the user's rotation operation by providing a control device 110 specialized for the three-dimensional navigation system.
