[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1 , which is a structural block diagram of a vehicle navigation route indication system provided by an embodiment of the present invention. The vehicle navigation route indication system provided by this embodiment includes:

[0033] A camera device 1 is installed at the headrest of the driver's seat, and is used to collect a front road image and transmit the front road image to the navigation route indication processing device 3; the front road image includes a road dividing line;

[0034] The route indication component 2 includes route indicator lights distributed on an indication status bar, wherein the indication status bar is arranged around the front windshield of the vehicle;

[0035] The navigation route indication processing device 3 is used for:

[0036] Receive the road image ahead, extract the road boundary and the indication status bar in the road image ahead, and determine each connection starting point at the bottom of the indication status bar, wherein each connection starting point corresponds to each road boundary, and the angle between the connecting line from the connection starting point to the corresponding road boundary terminal and the corresponding road boundary satisfies a preset angle range; and the road boundary terminal is the end closest to the connection starting point;

[0037] Determine the coordinates of each of the connection starting points in the indication status bar, and divide the indication status bar into n indication areas according to the coordinates of each of the connection starting points and the number of road dividing lines; wherein n is equal to the result of calculating the number of road dividing lines divided by two and minus one; n is greater than or equal to 1; for example, see Figure 6 , Figure 6 is the extracted road dividing line. In the figure, there are 8 road dividing lines, so n should be equal to 3;

[0038] When running the navigation service, in response to the road driving instructions of the navigation system, the route indicator light in the i-th indication area that is preset and corresponds to the road driving instructions is determined as the response light, and the response light is controlled to display with the preset lighting display effect that corresponds to the road driving instructions; wherein i is greater than or equal to 1 and less than or equal to n.

[0039] In the embodiment of the present invention, the camera device 1 uses a wide-angle camera to capture the road ahead information in a wide range. Figure 2 , Figure 2 The place pointed by the arrow is the camera installation position of the embodiment of the present invention. Figure 2 It can be seen that the camera captures the road ahead and also includes information about the lower area of ​​the vehicle's windshield. Figure 3 This is a panoramic view of a road taken by a camera device exemplarily provided in an embodiment of the present invention.

[0040] In an optional implementation, the camera device 1 includes a camera, a tilt sensor, a processing device and a driving device;

[0041] The camera is used to collect images of the road ahead;

[0042] The tilt sensor is used to detect the tilt angle of the driver's seat and transmit the tilt angle to the processing device;

[0043] The processing device is used to generate an angle adjustment instruction to the driving device according to the received tilt angle, wherein the angle adjustment instruction is used to instruct the camera to rotate and move at an angle information corresponding to the tilt angle;

[0044] The driving device is used to drive the camera to rotate and move at the corresponding angle information according to the received angle adjustment instruction.

[0045] For example, Figure 4 A schematic diagram of the structure of the camera device is given. The inclination sensor 12 is installed on the camera 11, and the driving device includes a rotation driving unit 13 (with a built-in servo to control the rotation of the camera device) and a moving driving unit 14 (which is embedded in the slide slot through a moving part so that the camera can move up and down). In specific implementation, the processing device (not shown in the figure) can control the driving device to drive the camera 11 to rotate and move according to the inclination angle collected by the inclination sensor 12.

[0046] In specific implementation, the driver can adjust the position of the camera 11 up and down according to the height of his eyes after sitting on the driving seat. Based on the angle position of the car when it leaves the factory, when the driver adjusts the seat angle, the camera 11 will also change the corresponding angle value counterclockwise or clockwise from the default angle according to the tilt angle detection value through the tilt sensor 12. For example, when the seat tilts back 10°, the camera 11 will rotate 10° clockwise to ensure that the road image captured by the camera 11 is consistent with the image information seen by the driver's naked eyes.

[0047] In an optional implementation, the indication status bar further includes an operation status light, and the operation status light and the route indicator light are respectively arranged in the upper and lower areas of the indication status bar;

[0048] Then, the extracting of the road boundary line and the indicator status bar in the front road image specifically includes:

[0049] Controlling the running status light in the indicator status bar to display the same color as the road dividing line;

[0050] Binarization is performed on the front road image to extract the road dividing line and the running status light; and according to the design of the indicating status bar and the running status light, the indicating status bar information is obtained.

[0051] To light up the operating status light, refer to Figure 5 The route indication component of the embodiment of the present invention is installed on the left and right sides of the windshield A and below. The light display area of ​​the component is divided into two parts. The upper area B of the indication status bar is composed of running status lights (not shown in the figure), and the lower area C of the indication status bar is composed of route indicator lights (not shown in the figure). Figure 2 It can be seen that when the camera device is shooting, the indicator status bar can be photographed.

[0052] In a specific implementation, after controlling the running status light and / or route indicator light in the indication status bar to display the same color as the road dividing line, the camera is controlled to shoot the current route condition from the driver's perspective, and the captured picture is transmitted to the navigation route indication processing device 3. At this time, the navigation route indication processing device 3 will binarize the image of the road ahead and extract the road dividing line and the indication status bar. The method of extracting the indication status bar can be: extracting the running status light and / or route indicator light after the binarization processing, and obtaining the indication status bar information based on the design of the running status light and / or route indicator light in the indication status bar, such as the position of the running status light between the indication status bars, thereby extracting the indication status bar.

[0053] Taking into account that the route indicator light needs to display the corresponding lighting effect in response to the road driving instructions, frequently changing the route indicator light is not very friendly to the route indicator light. Moreover, if you choose to control the route indicator light to display the same color as the road dividing line, since the road information may be changing, controlling the route indicator light to display the same color as the road dividing line and the route indicator light responding to the road driving instructions cannot be executed at the same time. Therefore, in the embodiment of the present invention, it is preferred to control the operating status light in the indication status bar to display the same color as the road dividing line.

[0054] Of course, in other implementations, the route indicator light and the running status light may also be respectively arranged in the upper and lower areas of the indication status bar.

[0055] In an optional implementation manner, the navigation route indication processing device is further used to:

[0056] When the navigation service is started, the operating status light is turned on.

[0057] In a specific implementation, when the driver starts the navigation service and starts the route indication component, the operating status light will light up to inform the driver that the device has entered the working state.

[0058] In an optional implementation, the number of the road dividing lines is determined by:

[0059] Determine the number of all the selected connection starting points and the number of road dividing lines;

[0060] Or, when extracting the road boundary lines in the front road image, the number of road boundary lines included is identified.

[0061] In an optional implementation, the dividing the indication status bar into n indication areas according to the coordinates of each connection starting point and the number of road dividing lines specifically includes:

[0062] Determine the number of road dividing lines and the number of roads that the road currently traveled has;

[0063] Arrange all the connection starting points from left to right according to the coordinate characteristics of the connection starting points;

[0064] The first connection starting point and the last connection starting point are eliminated, and the remaining connection starting points are combined in pairs according to the arrangement order, and the area between the two combined connection starting points is used as the indication area on the indication status bar, so as to obtain n indication areas corresponding to the number of roads.

[0065] In specific implementation, the camera will shoot the current route status from the driver's perspective. The captured image is transmitted to the navigation route indication processing device 3, which will then perform binary processing on the road image ahead and extract the road dividing line and the indication status bar. The extraction method can be: the road dividing line is generally white, and the operating status light of the route indicator light in the indication status bar is turned on to display white, thereby extracting the road dividing line and the indication status bar according to the preset threshold, such as Figure 6 As shown. In the next step of image information processing, points will be selected at a certain interval in the indicator status bar to extend and connect each extracted road boundary line, and analyze whether the angle of the connection is within the preset angle range, such as 180° (±5°). If it is within this angle range, the connection starting point of the road indicator component is determined. Set the lower left corner as the coordinate origin, with Figure 6 Taking 1 as an example, we will eventually find the coordinates of the eight connecting starting points A(0, a), B(0, b), C(c, 0), D(d, 0), E(e, 0), F(f, 0), G(g, 0), and H(h, 0).

[0066] To more clearly demonstrate the choice of the starting point of the connection, see Figure 7 Taking point C as an example, the navigation route indication processing device selects several points at the bottom of the indication status bar to extend the white road dividing line. For example, if point a and point c are selected and the angle values ​​of their connection points are not within the range of 180°±5°, they are excluded until point b is found and the angle value of its connection point is within the range of 180°±5°. Then point C is selected as the starting point of the connection with the analyzed road dividing line, which is used as the regional boundary point of the road indication status.

[0067] Next, after obtaining the coordinate information of each connection starting point, it will be calculated according to the ratio. For example, if the ratio is 10 times, all the obtained coordinate values ​​will be multiplied by 10.

[0068] When determining the number of roads, the total number of connection starting points can be divided by two and subtracted by one to obtain the current number of roads. For example, if 8 coordinate points are transmitted, it is determined that there are currently three lanes.

[0069] Then, the indication area is divided according to the coordinate values ​​and characteristics of the calculated connection starting points. For example, if the x-axis coordinate values ​​of point A and point B are zero, they are marked on the left side of the indication status bar, and then they are arranged according to the coordinate values, in the order of point A and point B. If the Y-axis coordinate value of point CH is zero, it is marked on the lower side of the indication status bar, and then they are arranged according to the coordinate values, in the order of point C, point D, point E, point F, point G, and point H. Finally, the coordinate point on the left is used as the starting point of the arrangement order, and the order is point A, point B, point C, point D, point E, point F, point G, and point H. Except for the first and last coordinate points, which are not processed, the remaining coordinate points are combined in pairs in order, and finally the road area is divided in the indication status bar. Figure 8 As shown, three indication areas are divided.

[0070] After the indication area is divided, the route indicator lights in the corresponding indication area are lit according to the navigation driving instructions transmitted by the navigation system, so that in the driver's perspective, the lit area seen is consistent with the road area, so as to achieve more intuitive road reminders and instructions.

[0071] In an optional implementation, the route indicator light in the indicator status bar light has the following display conditions:

[0072] A. When the road driving instruction is to drive straight, the route indicator light will light up green in the indication area corresponding to the drivable road. For example, if the information obtained is three lanes and the road driving instruction is to drive in the two left lanes, the route indicator lights in the indication areas corresponding to the two leftmost roads will light up at the same time;

[0073] B. When the road driving instruction is to turn left or right after several hundred meters, the navigation route indication processing device will control the red light to flash in the indication area corresponding to the road where the left or right turn is possible until the vehicle completes the left or right turn;

[0074] C. When the road driving instruction is to turn around, the blue light will be on in the indication area corresponding to the leftmost road where the U-turn can be made.

[0075] In addition to the three occasions mentioned above, other route indication occasions will also have different combinations of light colors and flashing times, so that the driver can judge the driving action and direction at first glance, and all indication status actions will be continuously updated in real time according to the latest navigation route and road conditions.
