For convenience of understanding, the present embodiment and the following embodiments will be described by taking an in-vehicle computer as an example.
Referring to fig. 2, fig. 2 is a schematic diagram of a first scene of a possible blind area provided by the present invention, and for ease of understanding, this embodiment will be described with reference to fig. 2.
In the above possible visual blind area scenario, vehicle A, B, C, D is a vehicle driving normally on a road, camera S is a camera without a blind area view, and P is a pedestrian preparing to cross the road or a person driving a non-motor vehicle and/or a motor vehicle, where P is illustrated as a pedestrian; in the above scenario, the vehicles B and C are decelerating and stopping because they have seen the pedestrian P preparing to cross the road, the vehicle a normally travels because the driver determines that the pedestrian P will not encounter the vehicle a when the vehicle a passes through, the vehicle D forms a visual blind area because of the enclosure of the vehicle A, B, C, and the vehicle D is extremely likely to collide with the pedestrian P because the vehicle a does not stop, in which the vehicle D is the target vehicle of the present embodiment and the pedestrian P is the target reminding object of the present embodiment.
It should be understood that, the above-mentioned obtaining of the movement track data corresponding to the target vehicle and the target reminding object, in combination with the above-mentioned scenario, may be understood as obtaining the movement track data of the vehicle D and obtaining the movement track data of the pedestrian P.
It can be understood that the manner of acquiring the current movement track data may be to acquire video data of the vehicle D and the pedestrian P within a period of time by using the camera S, acquire positioning data corresponding to communication devices on the vehicle D and the pedestrian P, and establish communication data for connection between the vehicle D and the pedestrian P communication device based on the internet of vehicles technology or the bluetooth technology, which is not limited in this embodiment. The video data, the positioning data and/or the communication data may be converted to obtain the current movement track data corresponding to the vehicle D and the pedestrian P, where the conversion mode is any technology capable of implementing the data conversion, and this embodiment is not limited thereto.
It should be further understood that, the process of determining whether the target vehicle and the target reminding object converge within the preset time according to the movement track data may be to first calibrate the obtained movement track data of the vehicle D in the above-mentioned scene, then calibrate the obtained movement track data of the pedestrian P in the above-mentioned scene, and determine whether the movement tracks of the vehicle D and the pedestrian P intersect again according to the extension lines of the movement tracks of the vehicle D and the pedestrian P, and if the intersection is determined, it is determined that the vehicle D and the pedestrian P collide with each other after a certain time.
It can be further understood that the preset time period may be automatically adjusted according to the time when the vehicle D leaves the scene, may be set by a manufacturer at the time of automobile delivery according to a general situation, or may be calculated according to trajectory data of intersection of the vehicle D and the pedestrian P, which is not limited in this embodiment.
In the concrete implementation, the current moving track data of the target vehicle D and the pedestrian P are obtained, and then whether the moving tracks of the target vehicle D and the pedestrian P are intersected in a future period of time is judged according to the extension lines of the moving track data of the target vehicle D and the pedestrian P, so that the traffic risk condition can be judged in advance, and a prerequisite condition is provided for avoiding traffic accidents.
Step S20: if yes, judging whether the identity information of the target reminding object can be obtained or not;
it should be noted that, when the target reminding object is a pedestrian, the corresponding identity information may be obtained through features of the pedestrian, such as appearance, wearing, and the like, when the target reminding object is a motor vehicle and/or a non-motor vehicle, the corresponding identity information may be obtained through a license plate of the vehicle and by combining features of the pedestrian and features of the vehicle, and the obtaining manner may be obtained by querying a local and/or third-party database, which is not limited in this embodiment.
It is to be understood that the identity information may include a name, a social identity, a job identity, age information, a combination thereof, and the like of the pedestrian P in the foregoing scenario, which is not limited in this embodiment.
In the specific implementation, when it is determined that the extension lines of the moving tracks of the vehicle D and the pedestrian P intersect within a period of time, the identity information of the target reminding object is acquired, if it is determined that the extension lines of the moving tracks of the vehicle D and the pedestrian P do not intersect within a period of time in the future, the current moving track data of the vehicle D and the pedestrian P can be continuously acquired, whether a new extension line corresponding to the current moving track data intersects is recalculated when the track data deviates from the extension lines, if the new extension line intersects, the identity information of the target reminding object is acquired, and if the new extension line does not intersect, the current moving track data of the vehicle D and the pedestrian P are continuously acquired until the preset time is exceeded.
Step S30: and if the target reminding object can be obtained, acquiring the identity information of the target reminding object, generating a voice warning reminder containing the identity information according to the identity information, and sending the voice warning reminder containing the identity information to carry out warning reminding on the target reminding object.
It should be noted that the voice warning reminder may be voice reminding data including the name of the pedestrian P, for example: if the name of the target reminding object is "zhang san", the voice warning reminder including the identity information may be voice data such as "zhang san, please note that the vehicle is coming ahead", and the voice data may be automatically generated by using the existing voice synthesis technology, which is not described in detail in this embodiment.
It is to be understood that the voice data may also be audio data with a familiarity sound of the target alert object, where the familiarity sound may be obtained synchronously when the identity information of the target alert object is obtained, or obtained by analyzing with a big data analysis tool, which is not limited in this embodiment.
It should be understood that, the sending of the voice warning reminder may be sending the voice warning reminder to an electronic device with a playing function near the target reminder object in a broadcast manner, or may be playing by the target vehicle, which is not limited in this embodiment.
In the specific implementation, when the identity information of the target reminding object is judged to be capable of being acquired, the acquired identity information is converted into the voice warning reminding with the identity information of the target reminding object, and then the voice warning reminding is sent out so that the target reminding object can hear the voice warning reminding.
The embodiment of the invention judges whether the target vehicle and the target reminding object converge by comparing the current moving track data of the target vehicle and the target reminding object for traffic safety of a visual blind area in road traffic, thereby realizing finding out the risk of traffic hidden danger in advance, and sends the dangerous information to the target reminding object at a first time in a complex traffic environment by acquiring the identity information of the target reminding object and integrating the identity information into voice warning reminding, so that the target reminding object immediately reacts after receiving traffic risk early warning, thereby avoiding the occurrence of traffic accidents, reducing the occurrence rate of traffic accidents when the vehicle runs, improving the running safety of the vehicle and further improving the driving experience of a driver.
In a possible embodiment, the step of prejudging whether the target vehicle and the target reminder object converge within a preset time period according to the corresponding current movement trajectory data includes:
step S101: according to the corresponding current movement track data, calculating the corresponding predicted distance of the target vehicle and the target reminding object at each future time point;
the predicted distance corresponding to each future time point may be a predicted distance corresponding to each time point of the target vehicle and the target reminder object at each future time point, which is obtained from the corresponding current movement trajectory data.
Step S102: and when the predicted distance is smaller than a preset threshold value, judging that the target vehicle and the target reminding object can be converged.
It should be noted that the preset threshold may be calculated according to the target vehicle running speed, may be set by an initializer during system initialization, or may be a combination of the two, the initializer sets a basic value, and the system calculates according to the vehicle running speed and then superimposes the basic value to obtain a true value, which is not limited in this embodiment.
In specific implementation, when the predicted distance is smaller than the preset threshold, it can be determined that the target vehicle and the target reminding object are intersected within the preset time, and then an early warning signal can be sent in advance to trigger subsequent steps.
In the embodiment of the invention, for the traffic safety of the visual blind area in the road traffic, the predicted distance is compared with the preset threshold value, so that the traffic risk early warning is further advanced, the system, the driver and the pedestrians are given sufficient reaction time, and the occurrence rate of traffic accidents in the driving process of the vehicle is further reduced.
In a possible embodiment, the step of calculating the predicted distance between the target vehicle and the target reminding object at each future time point according to the corresponding current movement track data includes:
step S1011: calculating the minimum predicted distance between the target vehicle and the target reminding object within preset time according to the corresponding current moving track data;
it should be noted that the preset time may be automatically adjusted according to the time when the target drives away from the scene, may be set by a manufacturer at the time of automobile shipment according to a general situation, and may be calculated according to trajectory data of intersection between the target vehicle and the target reminding object, which is not limited in this embodiment.
It is to be understood that the minimum predicted distance may be the minimum distance between the target vehicle and the target reminding object at each time point in the preset time range. Each time point may be a time interval set according to the vehicle-mounted computer, for example: 1 second, 5 seconds, 10 seconds, and may also be automatically adjusted according to the traveling speed of the target vehicle and the traveling speed of the target reminding object, for example: the time interval may be 5 seconds when the target vehicle runs at a speed of 20 km/h and the target reminding object runs at a speed of 1 m/s, and may be 1 second when the target vehicle runs at a speed of 40 km/h and the target reminding object runs at a speed of 2 m/s, which is not limited in this embodiment.
In a specific implementation, the minimum distance between the target vehicle and the target reminding object in a future period is calculated by acquiring the current moving track data of the target vehicle and acquiring the current moving track data of the target reminding object.
In the embodiment of the invention, for the traffic safety of the visual blind area in the road traffic, the minimum prediction distance is compared with the preset threshold value within the preset time, so that the reduction of the alertness of drivers and pedestrians caused by the danger and the false alarm caused by the repeated intersection of the moving tracks can be effectively avoided, and the occurrence rate of traffic accidents in the driving process of vehicles is further reduced.
In a possible embodiment, the step of determining whether the identity information of the target reminder object can be obtained includes:
step S201: establishing connection with the communication equipment of the target reminding object;
it should be noted that the communication device may be an electronic device such as a mobile phone, a smart watch, and a smart band that the target reminding object carries with, which is not limited in this embodiment.

In a specific implementation, by sending a connection request to the communication device, receiving the connection request and returning connection information at the communication device, the target vehicle can be determined to be connected with the communication device of the target reminding object after receiving the connection information.
Step S202: judging whether the identity information of the corresponding owner in the communication equipment can be acquired;
it should be noted that the identity information of the owner is the identity information of the target reminder object, and may be the identity information of the target reminder object for performing real-name authentication.
It is understood that the above determination may be that the target vehicle sends an identity information obtaining request to the communication device, and the communication device queries a database inside the communication device to obtain the identity information of the owner after receiving the request; the communication device may also query the server-side database to obtain the identity information of the owner after receiving the request, which is not limited in this embodiment, and when the result obtained by the query is empty, the communication device returns the identity information that cannot be obtained from the owner, and when the result obtained by the query is not empty, the communication device returns the identity information that can be obtained from the owner.
Step S203: if the identity information of the corresponding owner in the communication equipment can be obtained, judging that the identity information of the target reminding object can be obtained;
step S204: otherwise, judging that the identity information of the target reminding object cannot be acquired.
In a specific implementation, the target vehicle sends an identity information obtaining request to the communication device, and when receiving that the communication device cannot obtain the identity information of the owner, the target vehicle determines that the identity information of the target reminding object cannot be obtained; and when the target vehicle receives the identity information of the owner, the identity information of the target reminding object is judged to be acquired.
