Detailed Description
The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
As shown in FIG. 1, a flow 100 of one embodiment of a method for generating information in accordance with the present disclosure is shown. The method for generating information comprises the following steps:
s101, acquiring an electronic map of a target area and acquiring road information generated when at least one vehicle runs in a road network in the target area.
In the present embodiment, the execution subject of the method for generating information may acquire an electronic map of a target area. Here, the target area may be an area artificially designated according to actual needs. For example, the target area may be an area where road testing of an autonomous automobile is desired. For example, the target area may be an area where a city is located. In addition, the execution subject may further acquire road information generated when at least one vehicle travels in a road network within the target area. Here, the road information may include road obstacle information and traffic participant information.
Each of the at least one vehicle may have an obstacle sensing function. As an example, the at least one vehicle may be a vehicle having an automatic driving function. When a vehicle travels through a road network in a target area (manually driven or automatically driven), road environment information is acquired by sensors such as a laser radar, an ultrasonic radar, and a camera, and vehicle body Positioning information is acquired by a GPS (Global Positioning System), an IMU (Inertial measurement unit), and the like. Then, the vehicle may perform various analysis processes on the information acquired by the sensor, and generate road information, driving decisions, and the like according to a certain rule. For example, road obstacle information on a road, such as obstacle type, obstacle position, obstacle size, obstacle moving speed, and the like, may be analyzed.
Here, the electronic map may refer to an automatic driving map (or an automatic driving high-precision map) for guiding the driving of an automatic driving automobile. The autopilot map may construct a real-mapped virtual road environment model for the autopilot. For the automatic driving automobile, the automatic driving map can reduce the difficulty of environment perception, provide more perfect surrounding environment and more accurate positioning precision and reliability, and provide the automatic driving automobile for behavior decision. As an example, the autopilot map may include various information such as road-related information (e.g., the number of lanes, construction status, drivable areas, undrivable areas, intersection locations, etc.), lane information (lane line locations, curvatures/gradients, centerlines, lane property changes, etc.), traffic facility information (traffic lights, zebra stripes, stop lines, traffic signs, road isolation barriers, etc.).
In the present embodiment, the execution subject may be various electronic devices having information processing and generating functions, including but not limited to a smart phone, a tablet computer, a laptop portable computer, a desktop computer, and the like.
S102, carrying out statistical analysis on the information contained in the electronic map to obtain static road network information of the road network.
In this embodiment, the executing entity may perform statistical analysis on the information included in the electronic map, so as to obtain the static road network information of the road network. Here, the static road network information may be a description of the kind and number of road network contained elements (e.g., intersections, red street lamps, roundabouts, etc.) of the target area. Taking a scene that the unmanned vehicle enters the intersection as an example, after the unmanned vehicle enters the intersection, a series of actions including intersection parking waiting, intersection lane changing, traffic signal lamp identification, interaction with motor vehicles and pedestrians in the intersection and the like can be executed. Therefore, the difficulty of driving the unmanned vehicle is obviously increased by the large number of the intersections of the road network. Similarly, if the number of lanes in the road network increases and the number of lanes decreases, the probability of interaction between the driverless vehicle and other vehicles and the difficulty of lane selection may increase.
In some optional implementations of the present embodiment, the step S102 may specifically be performed as follows:
firstly, carrying out statistical analysis on at least one of the following information contained in the electronic map: the road comprises intersections, traffic lights, lane number increasing areas, lane number reducing areas, lane width, lane number, main road number, auxiliary road number and road isolation guardrail length.
In this implementation, the execution subject may perform statistical analysis on at least one of the following information included in the electronic map obtained in S101: intersections, red street lamps, lane number increasing areas, lane number decreasing areas, lane widths, lanes, main roads, auxiliary roads, road isolation guardrail lengths and the like. Therefore, statistical analysis results such as the number of intersections, the number of traffic lights, the number of lane increasing areas, the number of lane decreasing areas, lane width, the number of lanes, the number of main roads, the number of auxiliary roads, the length of road isolation guardrails and the like are obtained.
Then, the static road network information is generated based on the statistical analysis result, for example, the statistical analysis result is directly used as the static road network information.
In this implementation, the static road network information may comprise a variety of statistical analysis information. By the implementation mode, the static road network information comprising various information can be acquired, so that the acquired static road network information contains more abundant information.
And S103, analyzing the acquired road obstacle information to obtain dynamic road network information.
In this embodiment, the executing entity may analyze the road obstacle information acquired in S101, thereby obtaining dynamic road network information. Here, the dynamic road network information may include distribution of obstacles around the vehicle, the number of obstacles around the vehicle, traffic volume (e.g., traffic volume, pedestrian volume) at the intersection, and the like.
In some optional implementation manners of this embodiment, the foregoing S103 may specifically include the following: 1) counting the number of different types of obstacles in different time at different positions of a road network; and/or 2) counting the traffic volumes of the target intersections in the road network at different times; and/or 3) the number of different types of obstacles in a range taking the position of the vehicle as the center of a circle and taking the preset distance as the radius; and/or 4) determining the traffic distribution of the road network within a preset statistical period.
In this implementation, the executing entity may analyze the acquired road obstacle information to obtain the dynamic road network information by at least one of the following manners:
1) the number of different types of obstacles at different points of the road network at different times is counted.
In this implementation, the vehicle may generate road obstacle information in real time while traveling through the road network, and record the time and place at which the road obstacle information is generated. The road obstacle information may include an obstacle type, among others. As an example, the types of obstacles that the vehicle may recognize may include vehicles, pedestrians, bicycles, movable obstacles, immovable obstacles, unknown obstacles, and so on. In this way the executive may count the number of obstacles of different types at different points of the road network at different times. For example, the number of different types of obstacles of a site X of the road network may be counted over different time periods of the day, thereby forming a time series of the number of different types of obstacles for the site X. The execution entity may generate one of the dynamic road network information from different types of obstacle data of different locations of the road network at different times, e.g. directly take different types of obstacle data of different locations of the road network at different times as one of the dynamic road network information.
2) And (5) counting the traffic volumes of the target intersections in the road network at different times.
In this implementation manner, the execution subject may count the traffic volumes of the target intersections in the road network at different times. Here, the target intersection may be an intersection manually specified according to actual needs. The execution subject may generate one of the dynamic road network information according to the traffic volumes of the target intersection at different times, for example, directly take the traffic volumes of the target intersection at different times as one of the dynamic road network information.
3) And counting the number of different types of obstacles within a range taking the position of the vehicle as the center of a circle and taking the preset distance as the radius.
In this implementation, the execution subject may count the number of different types of obstacles within a range (i.e., within a predetermined range around the vehicle) with a preset distance as a radius (e.g., 30 meters, 50 meters, 100 meters, etc.) around the position of the vehicle as a center. The execution body may generate one of the dynamic road network information based on data of different types of obstacles within a predetermined range around the vehicle, for example, directly using the data of different types of obstacles within the predetermined range around the vehicle as one of the dynamic road network information.
4) And determining the traffic distribution of the road network in a preset statistical period.
In this implementation, the executive may determine the traffic distribution of the road network for a preset statistical period (e.g., one day, one week, etc.). The execution entity may generate one of the dynamic road network information from the traffic distribution of the road network within the statistical period, e.g. directly take the traffic distribution of the road network within the statistical period as one of the dynamic road network information. By the implementation mode, the dynamic road network information comprising various information can be obtained, so that the information contained in the obtained dynamic road network information is richer.
And S104, analyzing the acquired traffic participant information to obtain the characteristics of the traffic participants.
In this embodiment, the executing subject may analyze the traffic participant information acquired in S101, so as to obtain the traffic participant characteristic. Wherein the traffic participants may include vehicles, bicycles, pedestrians, and the like. By way of example, the traffic participant characteristic may include a degree to which the traffic participant complies with traffic regulations.
In general, an autonomous automobile may travel according to traffic regulations, and a scene that the autonomous automobile may handle is a scene in which other traffic participants comply with the traffic regulations. The autonomous automobile responds to and processes the aggressive driving behavior (e.g., a short-distance quick lane change) of the surrounding vehicles for a short time, and may have unreasonable driving behaviors such as sudden braking, collision, and the like, and thus, the degree of compliance of traffic participants with traffic regulations may also affect the driving of the autonomous automobile.
In some optional implementations of the embodiment, the traffic participant information may include traffic participant violation information and lane change information. And the executing body can analyze the acquired traffic participant information in at least one of the following ways, so as to obtain the traffic participant characteristics:
1) and carrying out statistical analysis on the traffic participant violation information sent by at least one vehicle to obtain the traffic participant violation characteristics.
In the implementation mode, the execution main body can perform statistical analysis on the traffic participant violation information sent by at least one vehicle, so that the traffic participant violation characteristics are obtained. For example, the number of traffic participant violations occurring over a predetermined time (e.g., over a day) may be counted, or the number of traffic participant violations occurring per predetermined number of kilometers over a predetermined time (e.g., per 100 kilometers of a day) may also be counted. Here, the violation may include various behaviors violating the road traffic regulation, such as a reverse run, an overspeed, an illegal parking, a vehicle entering a non-travel area, a pedestrian entering a lane exclusive to the vehicle, an overspeed, and the like. The enforcement agent may generate one of the traffic participant characteristics from the traffic participant violation characteristics, for example, by directly taking the traffic participant violation characteristics as one of the traffic participant characteristics.
2) And counting the change distance of the traffic participating vehicle when changing lanes and the vehicle speed when changing lanes.
In this implementation, the executing agent may count a change distance and a vehicle speed at the time of a lane change of the traffic-participating vehicle in the road network. Here, the change distance may refer to a distance from the tail of the vehicle to the head of the vehicle running on the upper side of the lane to be changed (i.e., the changed lane) before the vehicle changes the lane, and here, the side running vehicle may refer to a vehicle located behind the lane-changed vehicle after the vehicle changes the lane. The vehicle speed at the time of the change may include a longitudinal speed and a lateral speed. Taking fig. 2 as an example, fig. 2 includes a lane 1 and a lane 2, and a vehicle a traveling in the lane 1 intends to change lanes to the lane 2, and the side vehicle of the vehicle a is a vehicle B. The change distance is a distance d from the tail of the vehicle a to the head of the lane B, and the vehicle speed at the time of the change may include a longitudinal speed V1 and a lateral speed V2. The execution subject may generate one of the traffic participant characteristics from a change distance of the traffic participant vehicle at the time of changing the lane and a vehicle speed at the time of the change, for example, directly use the change distance of the traffic participant vehicle at the time of changing the lane and the vehicle speed at the time of the change as one of the traffic participant characteristics.
3) And counting the vehicle speed of the traffic participating vehicles.
In this implementation, the executing entity may count the vehicle speeds of the traffic participant vehicles within the road network and generate one of the traffic participant characteristics according to the vehicle speeds of the traffic participant vehicles, for example, directly take the vehicle speed of the traffic participant vehicle as one of the traffic participant characteristics. By the implementation mode, the traffic participant characteristics comprising various information can be obtained, so that the obtained traffic participant characteristics contain more abundant information.
S105, generating a road network representation of the road network according to the static road network information, the dynamic road network information and the traffic participant characteristics.
In this embodiment, the executive agent may combine the static road network information obtained in S102, the dynamic road network information obtained in S103, and the traffic participant characteristics obtained in S104 to obtain the road network representation of the road network. In practice, road network representations may be applied to aspects of road testing of autonomous vehicles. As an example, for a new road network, the road network image for the new road network may be quantitatively described from multiple dimensions of static road network information, dynamic road network information, and traffic participant information. The road network representation of the new road network is laterally compared with the road network representation of the known mature road network, so that the new road network can be intuitively and comprehensively recognized. Thus, the road network representation can be used for road network extension and road network selection for autonomous vehicles. As another example, the road network representation may be used to guide the selection of corresponding road network regions for different test purposes for dedicated and focused tests. For example, to detect the ability of an autonomous vehicle to safely pass through an intersection, an area corresponding to a road network image with a large number of intersections may be selected as a test area.
In some optional implementations of this embodiment, the method for generating information may further include the following steps not shown in fig. 1:
first, a road network representation is displayed for viewing by a user.
In this implementation, the executive agent may display the road network representation generated in S105 for viewing by the user. Here, the user may be a person who verifies the road network representation. The user can verify the road network representation displayed by the executive body according to the real condition of the road network in the target area, and if the information in the road network representation is found to be wrong, the user can input the modification information aiming at the wrong information.
Modification information sent by the user is then received, and the road network representation is modified in accordance with the modification information.
In this implementation, the execution agent may receive modification information sent by a user, and modify information in the road network representation according to the modification information. By the implementation mode, the user can modify the generated road network portrait, so that the modified road network portrait is more accurate.
With continuing reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of the method for generating information according to the present embodiment. In the application scenario of fig. 3, the terminal device 301 may first acquire an electronic map of a target area and road information generated when a large number of vehicles travel through a road network in the target area, where the road information includes road obstacle information and traffic participant information. Next, the terminal device 301 may perform statistical analysis on the information included in the electronic map to obtain static road network information of the road network. Then, the terminal device 301 may further analyze the acquired road obstacle information to obtain dynamic road network information. Then, the terminal device 301 may further analyze the obtained traffic participant information to obtain the traffic participant characteristics. Finally, the terminal device 301 may generate a road network representation of the road network based on the static road network information, the dynamic road network information and the traffic participant characteristics.
The method provided by the above embodiment of the present disclosure combines the characteristics of the auto-driving automobile to generate a road network representation capable of describing a road network from multiple dimensions, quantitatively describe the road environment in which the auto-driving automobile runs, and generate a road network representation suitable for the road test of the auto-driving automobile.
With further reference to fig. 4, a flow 400 of yet another embodiment of a method for generating information is shown. The flow 400 of the method for generating information comprises the steps of:
s401, acquiring an electronic map of a target area, and acquiring road information generated when at least one vehicle runs in a road network in the target area.
In this embodiment, S401 is similar to S101 of the embodiment shown in fig. 1, and is not described here again.
S402, carrying out statistical analysis on the information contained in the electronic map to obtain static road network information of the road network.
In this embodiment, S402 is similar to S102 of the embodiment shown in fig. 1, and is not described here again.
And S403, analyzing the acquired road obstacle information to obtain dynamic road network information.
In this embodiment, S403 is similar to S103 of the embodiment shown in fig. 1, and is not described here again.
S404, analyzing the acquired traffic participant information to obtain the characteristics of the traffic participants.
In this embodiment, S404 is similar to S104 of the embodiment shown in fig. 1, and is not described here again.
S405, generating a road network representation of the road network according to the static road network information, the dynamic road network information and the traffic participant characteristics.
In this embodiment, S405 is similar to S105 of the embodiment shown in fig. 1, and is not described here again.
S406, based on the road network image of the road network, the automatic driving difficulty evaluation is carried out on the road network.
In this embodiment, the executor may obtain a road network representation based on S405 and perform automatic driving difficulty evaluation on the road network.
As an example, the execution subject may have stored therein an evaluation rule in advance, for example, the evaluation rule may be a calculation formula for calculating one or more information in the road network representation to obtain a calculation result for representing the degree of difficulty of automatic driving. For example, a plurality of information items having a large influence on the driving of an autonomous vehicle in the road network representation may be manually selected, and the selected plurality of information items may be calculated using a predetermined calculation formula, thereby obtaining a calculation result.
As another example, an evaluation model may be stored in advance inside the execution body, and the evaluation model may be used to represent the correspondence between the road network representation and the automatic driving difficulty. In this way, the operator can input the road network image obtained in S405 to the evaluation model, and output the degree of difficulty of automatic driving from the evaluation model. The evaluation model can be obtained by adopting a machine learning method and utilizing a preset sample set for training. For example, an executive (the same as or different from the executive described above) used to train the evaluation model may train the evaluation model in the following manner: first, a sample set is obtained, wherein the sample comprises a sample road network representation and a sample autopilot difficulty corresponding to the sample road network representation.
