Currently, when displaying road information, the following methods are generally adopted: and sending the generated road information to a display terminal in the current vehicle for viewing by a driver of the current vehicle.
However, the inventors found that when road information is displayed in the above manner, there are often the following technical problems:
if the current vehicle is a large vehicle (e.g., a large transportation vehicle, a large truck, a large tank truck, etc.), the view of the rear following vehicle is easily blocked at night due to the large vehicle body size, and thus, it is difficult for the rear vehicle to timely predict the road condition in front, so that the rear following vehicle is easily caused to rear-end collision when the current vehicle is in a braking state, and further, traffic safety accidents occur.
The above information disclosed in this background section is only for enhancement of understanding of the background of the inventive concept and, therefore, may contain information that does not form the prior art that is already known to those of ordinary skill in the art in this country.

In a fourth aspect, some embodiments of the present disclosure provide a computer readable medium having a computer program stored thereon, wherein the program, when executed by a processor, implements the method described in any of the implementations of the first aspect above.
The above embodiments of the present disclosure have the following advantageous effects: by the road information display method of some embodiments of the present disclosure, the rear vehicle can be made to predict the road condition in front in time. Specifically, it is difficult for the rear vehicle to timely predict the road condition in front because: if the current vehicle is a large vehicle (for example, a large truck), the vehicle is large, and the view of the following vehicle is easily blocked at night, so that it is difficult for the following vehicle to predict the road condition ahead in time. Based on this, the road information display method of some embodiments of the present disclosure first acquires a vehicle speed value of a current vehicle and a road image captured by a vehicle front view camera. Then, the above road image is subjected to recognition processing to generate an image recognition result. Through the recognition processing, the method can be used for generating an image recognition result corresponding to the road image so as to be convenient for display.

Wherein the target projection device is located behind the current vehicle. The road detection result generated by the current vehicle can be transmitted to the target projection apparatus by transmission. Therefore, the projection equipment can project the road condition in front of the current vehicle behind the current vehicle. So that the following car at the rear can timely predict the road condition at the front. Thus, when the current vehicle is in a braking state, the following vehicle can know the situation in advance and decelerate. Therefore, the rear-end collision of the rear-end vehicle can be reduced to a certain extent. Further, the safety of road driving is improved.

In some embodiments, the execution subject of the road information display method may acquire the vehicle speed value of the current vehicle and the road image captured by the vehicle front view camera in a wired manner or a wireless manner. Wherein the current vehicle speed value may be the instantaneous speed at the current time. The road image may be an image of a road ahead of the current vehicle.
It should be noted that the wireless connection may include, but is not limited to, 3G/4G connections, wiFi connections, bluetooth connections, wiMAX connections, zigbee connections, UWB (ultra wideband) connections, and other now known or later developed wireless connection means.
Step 102, the road image is subjected to recognition processing to generate an image recognition result.
In some embodiments, the execution subject may perform recognition processing on the road image to generate an image recognition result. The road image can be identified through a preset image identification algorithm, so that an image identification result can be generated. Second, the image recognition result may include: obstacle identification information, lane line identification information, road identification information, and the like. The obstacle identification information may be information of an obstacle located in front of a lane in which the current vehicle is located. Second, the obstacle identification information may characterize the identification result of the dynamic obstacle.
For example, if the dynamic obstacle is a vehicle, the obstacle identification information may be: "there is an obstacle vehicle in front". Then, the obstacle identification information may also characterize the identification result of the static obstacle. For example, if the static obstacle is an obstacle such as a cone. The obstacle identification information may be: "static obstacle exists in front". In addition, if no obstacle is detected in the road image within a certain range (for example, 100 meters) in front of the lane where the current vehicle is located, the obstacle identification information may be "no obstacle is detected".
As an example, the image recognition algorithm described above may include, but is not limited to, at least one of: G-CRF (Gaus-conditional random field, gaussian conditional random field) model, densecRF (Fully-Connected Conditional Random Fields, fully connected conditional random field) model, MRF (MRF-Markov Random Field, markov conditional random field) model, and the like.
And step 103, in response to determining that the image recognition result meets a first preset obstacle condition, transmitting the vehicle speed value and the road image to the target projection device for display.
In some embodiments, the execution body may transmit the vehicle speed value and the road image to a target projection apparatus for display in response to determining that the image recognition result satisfies a first preset obstacle condition. Wherein the target projection device is located behind the current vehicle. The first preset obstacle condition may be that the obstacle identification information included in the image identification result is: "no obstacle detected". The target projection device is a projection device provided on the rear compartment of the current vehicle described above.
In practice, the road image and the current vehicle speed value may be sent to the target projection device for display when no obstacle is present in front of the current vehicle. Therefore, the road condition display device is used for displaying the front road condition for the following vehicle.
As an example, refer to fig. 2. The target projection device 201 as shown in fig. 2 may project the received information 202 onto the rear compartment of the current vehicle. The received information 202 may include, but is not limited to, at least one of: road images, obstacle vehicle images, current vehicle speed values, forward vehicle distance values, forward vehicle model, etc.
Optionally, the executing body may further execute the following steps:

Wherein, the static obstacle information may include: an obstacle distance value and an obstacle location area coordinate set. The second preset obstacle condition may be that the image recognition result includes obstacle recognition information as follows: "static obstacle exists in front". The obstacle distance value may be a distance value between the obstacle and the current vehicle.

And secondly, carrying out path planning on the current vehicle to obtain a current vehicle planning path. And planning the path of the current vehicle through a preset path planning algorithm to obtain a current vehicle planning path. Here, considering that there is a static obstacle in front of the road, the planned path of the current vehicle may be adjusted through path planning.
As an example, the path planning algorithm may include, but is not limited to, at least one of: RRT (Rapidly-Exploring Random Tree, sample-based path planning) algorithms, DWA (dynamic window approach, dynamic window path planning) algorithms, and the like.
And thirdly, transmitting the obstacle distance value, the obstacle position region coordinate set, the road image, the current vehicle planning path, the image recognition result, a preset current vehicle collision prompt identifier, a current vehicle deceleration identifier and a current vehicle emergency lane change identifier to the target projection equipment for display. The current vehicle collision prompt identifier can represent the identifier that the current vehicle is about to brake and adjust the route when an obstacle exists in front of the current vehicle. The current vehicle deceleration identification may be used to indicate that the current vehicle is in a decelerating state. For example, the current vehicle collision warning indicator may be an indicator of a front collision warning system activation. In practice, the moving state and the moving intention of the current vehicle can be synchronously displayed for the rear vehicle by displaying the information such as the planned path, the deceleration mark and the like of the current vehicle for the rear vehicle. Therefore, the rear vehicle can timely predict the road condition in front and know the current vehicle condition. Therefore, the rear-end collision of the rear vehicle can be further avoided.
Optionally, the executing body may further execute the following steps:
and a first step of acquiring a surrounding obstacle detection information set in response to determining that the image recognition result does not satisfy the second preset obstacle condition. The second preset obstacle condition may be that obstacle identification information included in the image identification result is: "static obstacle exists in adjacent lanes". Each surrounding obstacle detection information may correspond to an obstacle within a certain range (e.g., 50 meters) of the current vehicle to characterize the obstacle's information. The surrounding obstacle information may include: obstacle lane markings, surrounding obstacle speed values, surrounding obstacle movement paths, etc. The obstacle lane markings may be used to uniquely identify the lane in which the obstacle is located. The surrounding obstacle movement path may be a movement path of the obstacle within a certain time (e.g., 5 seconds).
And a second step of determining an obstacle prediction path corresponding to each surrounding obstacle detection information in the surrounding obstacle detection information set to obtain an obstacle prediction path set. Wherein the surrounding obstacle movement path may be input to the path planning algorithm to generate an obstacle predicted path. The obstacle prediction path may be used to characterize the lane change trend of the obstacle over a period of time (e.g., 5 seconds) thereafter.
And thirdly, transmitting the surrounding obstacle detection information set, the obstacle prediction path set, the image recognition result, the road image and a preset current vehicle lane keeping identifier to the target projection equipment for display. Here, the set of surrounding obstacle detection information and the set of obstacle predicted paths are transmitted to the target projection device, and the predicted path of the vehicle on the side of the current vehicle may be displayed for the following vehicle. So that the rear vehicle can be referred to. Thus, the safety of the vehicle driving is improved.
Optionally, the executing body may further execute the following steps:
and a first step of determining dynamic obstacle information in response to determining that the image recognition result meets a third preset obstacle condition. Wherein, the dynamic obstacle information may include: a dynamic obstacle speed value and a dynamic obstacle distance value. The third preset obstacle condition may be that the image recognition result includes obstacle recognition information as follows: "there is an obstacle vehicle in front". The determining of dynamic obstacle information may be: and determining dynamic obstacle information corresponding to the front obstacle vehicle in the road image through a preset obstacle tracking algorithm.
As an example, the obstacle tracking algorithm may include, but is not limited to, at least one of: TLD (Tracking-Learning-Detection), YOLO-v3 (You Only Look Once-Version 3) and the like.
And a second step of transmitting the current vehicle speed value, the dynamic obstacle distance value, the image recognition result, the road image, a preset current vehicle collision prompt identifier and a current vehicle emergency braking identifier to the target projection device for display in response to determining that the current vehicle speed value and the dynamic obstacle distance value meet a preset distance condition. The preset distance condition may be that emergency braking is started with the current vehicle speed value, and a stationary state is reached within the distance of the dynamic obstacle distance value. The current vehicle emergency brake identification may be an identification of a vehicle emergency brake system activation.
Optionally, the executing body may further execute the following steps:
and firstly, adjusting the planned path of the current vehicle to obtain an adjusted planned path in response to determining that the current vehicle speed value and the dynamic obstacle distance value do not meet the preset distance condition. The current vehicle planning path can be adjusted through the path planning algorithm, and the adjusted planning path is obtained.
And a second step of transmitting the current vehicle speed value, the dynamic obstacle distance value, the image recognition result, the road image, the adjusted planned path, a preset current vehicle collision prompt identifier and a current vehicle lane change identifier to the target projection equipment for display.
Optionally, the executing body may further execute the following steps:
the method comprises the first step of obtaining a rear road image shot by a rear camera of a current vehicle.
And secondly, detecting the distance of the obstacle from the rear road image to obtain a rear obstacle distance value. And detecting the obstacle distance of the rear road image through the image recognition algorithm to obtain a rear obstacle distance value.
And a third step of performing a voice prompt operation in response to determining that the rear obstacle distance value is smaller than a preset distance threshold and that the current vehicle is in a decelerating state. The voice prompt operation may be to control the voice device to broadcast a preset prompt voice. For example, the prompt voice may be "please note deceleration" or the like.
The above embodiments of the present disclosure have the following advantageous effects: by the road information display method of some embodiments of the present disclosure, the rear vehicle can be made to predict the road condition in front in time. Specifically, it is difficult for the rear vehicle to timely predict the road condition in front because: if the current vehicle is a large vehicle (for example, a large truck), the vehicle is large, and the view of the following vehicle is easily blocked at night, so that it is difficult for the following vehicle to predict the road condition ahead in time. Based on this, the road information display method of some embodiments of the present disclosure first acquires a vehicle speed value of a current vehicle and a road image captured by a vehicle front view camera. Then, the above road image is subjected to recognition processing to generate an image recognition result. Through the recognition processing, the method can be used for generating an image recognition result corresponding to the road image so as to be convenient for display. Finally, the vehicle speed value and the road image are transmitted to a target projection device for display in response to determining that the image recognition result meets a first preset obstacle condition. Wherein the target projection device is located behind the current vehicle. The road detection result generated by the current vehicle can be transmitted to the target projection apparatus by transmission. Therefore, the projection equipment can project the road condition in front of the current vehicle behind the current vehicle. So that the following car at the rear can timely predict the road condition at the front. Thus, when the current vehicle is in a braking state, the following vehicle can know the situation in advance and decelerate. Therefore, the rear-end collision of the rear-end vehicle can be reduced to a certain extent. Further, the safety of road driving is improved.
