1 and 2, a smart voice navigation system 100 according to an embodiment of the present invention includes a controller 101 for generating route guidance information based on GPS position information and object information, And a camera unit 105 for photographing the frontal direction of the vehicle.

The control unit 101 can generate the navigation information to be provided to the user based on the GPS position information and the object information to the destination when the user inputs the destination.

The control unit 101 recognizes object information such as a road signboard, a road surface marker, and a lamp stand in the image photographed through the camera unit 105, and generates the guidance information for the route to the destination set by the user.

The control unit 101 can learn the recognized object information by comparing the recognized object information with the previously stored object information through the photographed image. The previously stored object information may be public data provided by the National Police Agency, the Traffic Safety Corporation, and the like.

That is, the control unit 101 can learn the recognized object information by comparing the recognized object information from the image photographed through the camera unit 105 with public data, which is previously stored object information.

Also, the control unit 101 may generate the location information of the user through the GPS location information, and may generate the route guidance information by combining the location information and the object information of the user.

For example, when the destination is Seoul, the control unit 101 recognizes images and characters such as characters, arrows, and the like through the road sign 201 on the front of the vehicle, compares the images and characters with previously stored object information, Quot ;, " entering the road on the left side ".

In addition, when the user travels for about 1 km through the GPS position information and reaches the branching point, the control unit 101 can generate information such as " entering the road on the left side toward Seoul ".

The control unit 101 can generate not only objects displayed on roads such as road signs, but also GPS information by analyzing GPS location information in real time and also through building information near the current location.

For example, if it is necessary to make a right turn with the building A 100 m ahead, the control unit 101 synthesizes the information "turn right after driving 100 m" and the information "turn right with A building" Right turn 'can be generated.

In generating the route guidance information, the control unit 101 can analyze the real-time traffic situation such as an accident, obstruction of road, construction, etc., and generate the shortest distance guidance information.

In addition, the control unit 101 can generate driving information in consideration of real-time weather information such as night, mist, snow, rain, and the like.

For example, the control unit 101 can generate driving information for driving a headlamp at night, and generate driving information for driving a tail lamp together with information for slowing down in a rainy and fog situation.

The control unit 101 analyzes the image of the front side of the vehicle photographed by the camera unit 105, and can generate driving information suitable for situations such as an interval with the preceding vehicle, a lane departure, and the like.

Further, the improved road information can be generated by analyzing the images photographed in real time and learning traffic conditions.

The control unit 101 can recognize characters and images included in the image by analyzing the captured images through a Deep Learning based method such as a Convolution Neural Network (CNN).

The control unit 101 may provide the generated guidance information and driving information to the user through the output unit 103 as a voice or a head-up display of the windshield of the vehicle.

For example, the control unit 101 searches for a route to be bypassed through an image of a construction, an accident, a road closure, and a police signal which are not included in the real-time traffic information on the route of the generated route guidance information, It is possible to provide the user with a shorter distance to the destination compared with the route information.

In addition, when the vehicle invades the lane through the photographed image, the control unit 101 can generate information about the lane incursion and provide it to the user.

The output unit 103 can output the information generated by the control unit 101 either visually or visually.

The output unit 103 can output the information generated by the control unit 103 as audio information, and display the generated information on one side of the head-up screen to output it as time information.

The camera unit 105 can photograph the image of the front side of the running vehicle in real time.

The photographed image can be analyzed by the control unit and used to generate the route guidance information.

The control unit 101 can generate the guidance information by combining the information of the object and the building in the photographed image and the previously stored object information on the object.

In addition, the control unit 101 can recognize information not included in GPS position information such as an accident, a road closure, a police signal, etc. in the photographed image, and can generate a bypass route to update the generated route guidance information.

The control unit 101 may measure the distance between the building and the vehicle recognized from the photographed image, and may generate more accurate guidance information based on the measured distance information and the GPS position information.

For example, if the distance to the building A is 100 m from the GPS position information, but the distance from the building A measured through the captured image is 50 m, the control unit 101 determines that the distance from the vehicle to the building A is 50 m It is possible to update the previously created route guidance information.

In addition, the control unit 101 can recognize the specific events and the weather such as the distance from the preceding vehicle, the lane departure, the accident scene, etc., and extract the information related to the running and provide the running information.

For example, when an accident scene is recognized on a photographed image, the control unit 101 can generate and provide driving information indicating that an accident has occurred ahead of the driver, It is possible to generate and provide driving information.

3 is a diagram illustrating an embodiment of smart voice navigation according to an embodiment of the present invention.

3, the control unit 101 may output the generated guidance information and driving information to the audio information 301 or the time information 303 through the output unit 103 as well as the voice.

Since the route guidance information and the travel information are provided to the user in real time through the voice information 301 and the time information 303 displayed on the head-up screen, the user can keep gazing forward while driving.

In addition, since the user gazes at the front face while driving and receives accurate guidance information and driving information through the voice and head-up screen, the user has to look at the screen of the navigation frequently to check the accurate guidance information. Can be solved.
