In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad application.

The road condition information display system provided by the application can be applied to the application environments shown in fig. 1 and fig. 2. Wherein:

(1) The extraction device 1 illustrated in fig. 1 enables networking between a driving vehicle and a traffic light system. The extraction device 1 provided at the head of the driving vehicle is connected to the display device 4 provided at the tail of the driving vehicle via the connection harness 6. On one hand, the extraction device 1 is mainly used for receiving the real-time position information transmitted by the positioning device 3, and inquiring the intersection information adapted to the real-time position information from the traffic light system based on the real-time position information. On the other hand, when it is determined that the corresponding road condition picture is not captured by the camera device 2 or the captured road condition picture has low definition, the queried intersection information is transmitted to the display device 4 through the connecting wire harness 6.

(2) The imaging device 2 illustrated in fig. 1 is provided in a vehicle head of a driving vehicle. The imaging device 2 is connected to the display device 4 via a connection harness 5. The camera device 2 is mainly used for shooting and identifying traffic light information of a front intersection on one hand, and converting a road condition picture into a first target road condition picture adaptive to intersection information according to a corresponding image conversion rule when a driving vehicle is determined to drive the intersection based on the shot road condition picture. The camera device 2 is mainly used for transmitting the converted first target road condition image to the display device via the connecting wire harness 5 when it is determined that the first target road condition image is successfully converted.

(3) The positioning device 3 illustrated in fig. 1 is provided at the head of the driving vehicle and is connected to the extraction device 1 by a connection harness 7. It should be noted that the positioning device is mainly used for positioning the driving position of the driving vehicle (for example, the actual position of the intersection where the vehicle is located and the vehicle passing direction), and transmitting the real-time position information to the extraction device 1 through the connection harness 7 when it is determined that the driving vehicle travels to the intersection based on the positioned real-time position information.

(4) The display device 4 illustrated in fig. 2 will be connected to the image pickup device 2 and the extraction device 1 in turn by a connection harness 5 and a connection harness 6. The display device 4 arranged at the tail of the driving vehicle is mainly used for receiving the first target road condition image transmitted by the camera device 2, or receiving the road condition information transmitted by the extraction device 1, and displaying the traffic information indicator at the crossroad and the traffic information displayed in real time based on the received first target road condition image or road condition information so as to remind the rear vehicle.

The road condition information display system can be used for the tail of a large vehicle, and can intelligently display traffic light signals of a front crossroad based on the display system. Before the large-scale vehicle runs to the crossroad, the system can automatically acquire the traffic information indicator board at the crossroad in front, display the traffic information in real time, and display the state of the traffic signal lamp on the display device arranged at the tail of the vehicle in real time to help the driver of the vehicle behind make judgment and response measures in time, so that the phenomena of rear-end collision, red light running and the like are avoided, traffic jam is avoided, and the safety of the vehicle and the pedestrian is ensured.

In one embodiment, as shown in fig. 3, a road condition information display system 300 is provided, which is described by taking an example that the system 300 is applied to a driving vehicle illustrated in fig. 1 and fig. 2, where the system 300 includes a positioning device 301, an extracting device 302, a camera 303 disposed at a head of the driving vehicle, a converting device 304, and a display device 305 disposed at a tail of the driving vehicle, where:

a positioning means 301 for positioning a driving position of the driven vehicle and transmitting the real-time position information to the extracting means when it is determined that the driven vehicle travels to the intersection based on the positioned real-time position information.

Specifically, the positioning device is also used for positioning the passing direction of the driving vehicle, and transmitting the real-time position information to the extraction device when the driving vehicle is determined to run to the crossroad by combining the positioned real-time position information and the real-time direction information; wherein the traffic direction includes a traveling direction when the vehicle is driven through the intersection, and the traveling direction includes at least one of a west-east direction, an east-west direction, a south-north direction, and a north-south direction.

In one embodiment, on the one hand, the Positioning device is further configured to position the driving position of the driving vehicle based on a built-in GPS (Global Positioning System) locator. On the other hand, the positioning device is also used for acquiring a steering signal transmitted by a steering system of the automobile and determining the passing direction of the driving vehicle based on the steering signal. It should be noted that the steering system of the vehicle is a device for changing or maintaining the driving or reverse direction of the vehicle, and the steering system of the vehicle functions to control the driving direction of the vehicle according to the intention of the driver. Therefore, the positioning of the real-time position information and the real-time direction information is carried out based on the GPS positioner and the automobile steering system, and the positioning precision is further improved.

Based on the above embodiment, when the positioning device locates the driving position of the driving vehicle based on the built-in GPS locator, the positioning device is further configured to calculate the separation distance between the located current position and the front intersection, and determine whether the positioning device has a fault based on the change of the separation distance and the driving condition of the vehicle. For example, when it is determined that the driving vehicle is in a driving state, and the distance interval has not changed within 15 minutes, or the change amplitude of the distance interval is smaller than a preset change threshold, it is determined that the positioning device has a fault, and in the current embodiment, a light alarm built in the positioning device is further triggered to give an alarm. It should be noted that, the above-mentioned change threshold and the change time of the separation distance may be set by themselves according to actual situations, and the embodiment of the present application is not limited to this. Therefore, on the one hand, based on the change condition of the spacing distance and the driving condition of the vehicle, the fault state of the positioning device can be effectively identified, and the condition that the positioning data which fails is transmitted to the extraction device to influence the positioning accuracy of the crossroad is avoided. On the other hand, when the positioning device is determined to have a fault, the built-in light alarm of the positioning device gives an alarm, the attention of a driver can be attracted, the driver is reminded to maintain the fault positioning device in time, and the positioning efficiency of the crossroad is indirectly improved.

In one embodiment, the extracting device is connected to the traffic light system through a wired and/or wireless connection mode, and when the extracting device determines that the driving vehicle runs to the intersection based on the acquired real-time position information, the traffic information indicator at the intersection can be automatically extracted from the traffic light system according to the real-time position information, so that the traffic information displayed in real time. The traffic light system is a system that performs signal control on intersections, pedestrian crossings, and loop entrances and exits in a highway and urban road traffic control system, and the traffic light information includes at least one of light restriction information (e.g., red light restriction information and green light restriction information), light countdown length information (e.g., traffic light digital information with time record), and driving direction restriction information (e.g., restriction information that may restrict a left turn or a right turn of a vehicle).

The extracting device 302 is used for acquiring intersection information corresponding to the real-time position information, wherein the intersection information comprises a traffic information indicator positioned at an intersection and traffic information displayed in real time; the traffic information includes at least one of light restriction information, light countdown length information, and driving direction restriction information.

Specifically, the extraction device is connected to the remote server, and the extraction device is further configured to issue a request instruction to the remote server to trigger the remote server to query and feed back the intersection information according to the acquired request instruction; the request instruction carries real-time position information; the extraction device is also used for generating and issuing the request instruction again when the intersection information which is fed back by the remote server and is adaptive to the real-time position information is not received in the determined corresponding time interval, and triggering the display device to display the alarm information which correspondingly reflects the road condition information acquisition failure in real time when the intersection information is not acquired in the determined continuous preset times.

In one embodiment, the remote server is connected to the traffic light system and the extraction device, and when the remote server acquires a request command issued by the extraction device, the remote server analyzes real-time position information from the request command and queries corresponding intersection information from the traffic light system based on the real-time position information. In one embodiment, the traffic light system divides the traffic light information of the whole city according to regions, and when the traffic light system acquires the real-time position information, the traffic light system searches corresponding intersection information from the divided corresponding regions based on the minimum city region where the driving vehicle is located, so that the intersection information searching efficiency is improved.

The camera 303 is configured to convert the road condition picture into a first target road condition image adapted to the intersection information according to a preset conversion rule when it is determined that the driving vehicle travels to the intersection based on the road condition picture shot in real time.

Specifically, the camera device is further configured to, when it is determined that the driving vehicle is driven to the intersection based on the road condition picture shot in real time, split at least one intersection picture of a first road condition image with lighting restriction information, a second road condition image with lighting countdown length information, and a third road condition image with driving direction restriction information from the road condition picture based on a preset image splitting rule, and use the intersection picture as a first target road condition image; the light restriction information comprises at least one of red light information, yellow light information and green light information; the camera device is also used for carrying out image registration on the converted first target road condition image and a preset reference image; and when the image registration is determined to be failed, performing image enhancement processing on the first target road condition image based on a high-frequency detail enhancement mode so as to enable the image definition of the first target road condition image to be adaptive to a preset definition threshold value.

In one embodiment, the camera device comprises a camera body and a camera turntable, wherein the camera body is arranged on the camera turntable, and the camera turntable is used for adjusting the rotation angle of the camera body, so that the camera can shoot road conditions around a driving vehicle at multiple angles. The camera device is used for dividing a first road condition image with red, yellow and green traffic light information, a second road condition image with time record, or a third road condition image with a restriction arrow record from a road condition image reflecting a road condition picture based on a preset image division rule (such as a gray threshold division rule, an area division rule and the like) when the driving vehicle is determined to drive to an intersection based on the road condition picture shot in real time. In one embodiment, the camera device is further used for outputting the real-time command state of the traffic light based on the divided first to third road condition images. For example, the real-time commanding state may be a first commanding state for limiting the vehicle to stop, a second commanding state for limiting the vehicle to turn left, a third commanding state for allowing the vehicle to pass, and the like, which is not limited in the embodiment of the present application. Therefore, the extracted real-time command state of the traffic lights can help the driver of the rear vehicle to make judgment and response measures in time, the traffic violation phenomena such as vehicle rear-end collision, red light running of the vehicle and the like are avoided, and the safety of the vehicle and the pedestrian is ensured.

In one embodiment, the camera device is further configured to, when it is determined that the image definition of the corresponding target road condition image is smaller than the standard image definition (i.e., a preset definition threshold), that is, when it is determined that the image registration fails, improve the image definition of the corresponding target road condition image based on a high-frequency detail enhancement manner, so that the image definition of the first target road condition image is adapted to the preset definition threshold. Of course, the image definition of the corresponding target road condition image can be adjusted by the camera device in modes of defogging, contrast enhancement, stretching recovery and the like. Therefore, by the aid of the image enhancement mode, the real-time command state of the traffic light can be guaranteed to be recognized even in extreme weather conditions such as haze weather, and the recognition efficiency of road condition information is improved.

The conversion device 304 is connected to the extraction device 302 and the camera device 303 respectively, and is configured to trigger the extraction device 302 to transmit the acquired intersection information to the display device 305 when it is determined that the conversion of the first target road condition image fails, and trigger the camera device 303 to transmit the converted first target road condition image to the display device 305 when it is determined that the conversion of the first target road condition image succeeds, and the display device 305 displays the road condition information in real time to remind a vehicle behind.

Specifically, the camera device is further configured to transmit the conversion state of the road condition picture to the conversion device. The conversion device is also used for monitoring the conversion state of the road condition picture at regular time. The display device comprises a display for displaying the road condition information in real time.

In one embodiment, the conversion device is further configured to query a conversion state of the road condition picture according to a preset interval time, trigger the extraction device to transmit the acquired intersection information to the display device when it is determined that the conversion of the corresponding first target road condition image fails, and trigger the camera device to transmit the converted first target road condition image to the display device when it is determined that the conversion of the first target road condition image succeeds, so that the display device displays the road condition information in real time. Wherein:

referring to fig. 2, the display effect of the traffic information may refer to the traffic information displayed by the display device illustrated in fig. 2, that is, the traffic information actually displayed on the traffic light. It should be noted that, since the intersection information recognized by the camera device is information actually displayed on the traffic lights at the intersection and information actually seen by the vehicle driver, and has an actual reference value, the present embodiment preferentially considers that the traffic information indicator at the intersection is displayed on the basis of the intersection information recognized by the camera device, and the traffic information displayed in real time is displayed.

In the above road condition information display system, when acquiring the road condition information of the corresponding intersection, on the one hand, when determining that the driving vehicle is driven to the intersection through the positioning device, the intersection information is acquired through the extracting device based on the currently positioned real-time position information. On the other hand, when the driving vehicle is determined to drive to the crossroad through the camera device based on the shot road condition picture, a first target road condition image adaptive to corresponding intersection information is obtained through conversion based on the current shot road condition picture. Therefore, timely acquisition of road condition information is guaranteed and data acquisition efficiency is improved through the various information acquisition modes. In addition, when the road condition information is displayed, the intersection information identified by the camera device is preferably considered, and when the fact that the camera device cannot identify the intersection information is determined through the conversion device (namely the first target road condition image conversion fails), the extraction device is triggered to transmit the acquired intersection information to the display device, so that the real-time display efficiency of the road condition information is improved, the display device arranged at the tail of the vehicle can display the traffic road condition of the front intersection in real time, a driver of a vehicle behind can be helped to make judgment and response measures in time, the phenomena of rear-end collision, red light running and the like are avoided, traffic congestion is avoided, and the safety of the vehicle and pedestrians is guaranteed.

In one embodiment, the display device is further configured to, when it is determined that the intersection information is received, convert the intersection information into a corresponding second target road condition image according to a preset image conversion rule, and display the second target road condition image in real time.

Specifically, the display device displays the second target road condition image in real time through a built-in display screen. In one embodiment, when the images to be displayed include a first image to be displayed with red, yellow and green traffic light information, a second image to be displayed with time record, and a third image to be displayed with restriction arrow record, the display screen is partitioned, and the specific display effect can refer to fig. 2, where fig. 2 shows that in the leftmost display area, the first image to be displayed is displayed as the first image to be displayed reflecting the red, yellow and green traffic light information, in the middle display area, the third image to be displayed is displayed as the third image to be displayed reflecting the driving direction restriction information, and in the rightmost display area, the second image to be displayed is displayed as the second image to be displayed with time record. Of course, in an embodiment, the first to third images to be displayed may be aggregated into a unified target image to be displayed, and at present, the target image to be displayed is displayed through a built-in display screen by a display device, so as to achieve the effect of displaying the traffic information displayed by the traffic information indicator at the intersection in real time.

The display device is further used for acquiring traffic jam conditions in a future preset time period based on the received first target road condition image or the second target road condition image, and prompting traffic jam information when the fact that traffic jam exists in the future preset time period is determined based on the traffic jam conditions.

Specifically, the display device is further configured to determine a historical traffic jam condition in the historical time period based on the received first target road condition image or the second target road condition image, calculate the number of times of traffic jam occurring in the historical time period based on the historical traffic jam condition, and when the calculated number of times of traffic jam is greater than a preset number threshold, it is determined that traffic jam may occur at the intersection in a future preset time period. In the current embodiment, the display device is further configured to generate corresponding traffic congestion information, and prompt the traffic congestion information. In one embodiment, the display device is wirelessly (of course, wired connection may also be adopted, which is not limited in this embodiment of the present invention) connected to a handheld terminal (e.g., a mobile phone, a tablet computer, etc.) of the driver, and the traffic congestion information generated by the display device is wirelessly transmitted to the handheld terminal, and the traffic congestion information is displayed on a display screen external to the handheld terminal.

In the above embodiment, through the built-in display screen of the display device, the corresponding image to be displayed is displayed, and the traffic information displayed by the traffic information indicator at the intersection can be displayed in real time to remind the vehicle behind. The display device is used for predicting the traffic jam condition in the future preset time period, so that the driver can be helped to predict the traffic jam condition in the future preset time period, and an avoidance strategy is made in time according to the prediction result, for example, the intersection is bypassed, a driving route with relatively slow traffic is selected, and the like, and the safety of vehicles and pedestrians is ensured by avoiding the traffic jam.

In one embodiment, the system further comprises a road condition detecting device and an alarm device, wherein:

the road condition detection device is used for monitoring the driving road conditions of the vehicles around the driving vehicle, calculating the spacing distance and the relative driving speed between the driving vehicle and other driving vehicles when other driving vehicles exist around the driving vehicle, and outputting an alarm signal to the alarm device to trigger the alarm device to give an alarm when the collision risk between the driving vehicle and other driving vehicles is determined according to the calculated spacing distance and relative driving speed.

Specifically, the road condition detection device is further configured to detect a driving road condition of the vehicle around the driving vehicle through a built-in vehicle-mounted radar, and based on a detection result of the vehicle-mounted radar, when it is determined that there are other driving vehicles around the driving vehicle, obtain a separation distance between the driving vehicle and the other driving vehicles output via the vehicle-mounted radar, and a relative driving speed. In one embodiment, the road condition detecting device is further configured to, when it is determined that the calculated distance is smaller than the preset first distance threshold, that is, the distance between the two vehicles is considered to be too close, and there is a collision risk, output an alarm signal to the alarm device to trigger the alarm device to alarm. In one embodiment, the road condition detecting device is further configured to determine that the calculated distance is greater than a preset first distance threshold and less than a preset second distance threshold, and that the relative driving speed between the two vehicles is greater than a preset speed threshold, that is, it is determined that the driving speed of the driven vehicle is too high and there is still a collision risk between the two vehicles, and at this time, still output an alarm signal to the alarm device to trigger the alarm device to alarm.

In one embodiment, the road condition detecting device may also detect a moving obstacle around the driven vehicle in the above-mentioned detection manner, determine whether there is a collision risk between the driven vehicle and the detected moving obstacle, and output an alarm signal to the alarm device to trigger the alarm device to alarm when it is determined that there is a collision risk. Therefore, through the multiple alarming mode, the collision risk between the driving vehicle and other surrounding driving vehicles and moving obstacles is further avoided, and the safety of the vehicles and pedestrians is ensured.

The road condition detection device is also used for monitoring a fixed obstacle in front of the driving vehicle, calculating the spacing distance between the driving vehicle and the fixed obstacle when the fixed obstacle is determined to exist in front of the driving vehicle, and outputting an alarm signal to the alarm device when the collision risk between the driving vehicle and the fixed obstacle is determined to exist based on the real-time running speed of the driving vehicle.

Specifically, the road condition detection device is further configured to detect a fixed obstacle in front of the driving vehicle by a built-in vehicle-mounted radar, and based on a detection result of the vehicle-mounted radar, when it is determined that the fixed obstacle exists in front of the driving vehicle, obtain a separation distance between the driving vehicle and the fixed obstacle, which is output via the vehicle-mounted radar. In one embodiment, the road condition detecting device is further configured to calculate a collision time when the driving vehicle collides with the fixed obstacle according to the detected separation distance between the driving vehicle and the fixed obstacle and the real-time driving speed of the driving vehicle, and when the collision time is determined to be greater than a preset first time threshold, that is, when the driving vehicle is far away from the fixed obstacle, the driving vehicle has enough time to adjust the driving route of the vehicle, and at this time, the warning signal is not output. When the collision time is determined to be smaller than a preset second time threshold value, namely the driving vehicle is close to a fixed obstacle, the driving route may not be adjusted in time, and the collision risk exists between the driving vehicle and the fixed obstacle, at the moment, an alarm signal is output to the alarm device to trigger the alarm device to give an alarm.

In one embodiment, the alarm device may comprise at least one of a buzzer, a flashing alarm, a sound and light alarm, etc., and the alarm signal may further be understood as a trigger signal which, when received by the alarm device, will be triggered and enter a corresponding operating mode for alarming. Of course, there are many alarm modes of the alarm device, for example, emitting an aural alarm sound, selecting a short message or voice to give a reminder, and displaying the alarm information through a preset display screen, and the embodiment of the present application does not limit this.

In the embodiment, when collision risks between the driving vehicle and other surrounding driving vehicles, moving obstacles or fixed obstacles are determined, the alarm device gives an alarm to prompt a driver to change a driving route in time, collision between the driving vehicle and a front vehicle or a front obstacle is avoided, rear-end collision of the vehicle is avoided, and safety of the vehicle and pedestrians is guaranteed.

Step S406, when it is determined that the driving vehicle runs to the intersection based on the road condition picture shot in real time through the camera device, the road condition picture is converted into a first target road condition image adaptive to the intersection information according to a preset conversion rule.
