The data to be acquired can be a point cloud image, a video image or a driving track of a road, and the like.
The following describes a data acquisition method of road information provided by the present invention with reference to fig. 1 to 3.
First, a data collection method of road information according to an embodiment of the present invention will be described with a server as an execution subject.
Fig. 1 is a schematic flow chart of a data acquisition method for providing road information at a server side according to the present invention. Referring to fig. 1, a data acquisition method for road information, applied to a server, includes:
step 101: and acquiring a target area range and a target time period of data to be acquired, wherein the data to be acquired at least comprises data acquired from the vehicle-mounted networking equipment.
When data in the selected area range need to be acquired, the selected area range is used as a target area range of the data to be acquired, and the target time period is determined by setting the time of the data in the required target area range.
The target area range may be an area range selected around the point a, or may be a route from the point a to the point B, and the route is taken as a target area range. Specifically, for example, whether a parking lot exists around the point a needs to be confirmed, an area around the point a may be selected as a target area range, data stored by a vehicle in which the high-precision map application is installed is acquired in the target area range, and whether a parking lot exists is determined according to the acquired data; for example, whether a traffic jam road section exists on a route between the site a and the site B needs to be inquired, the route between the site a and the site B can be selected as a target area range, and after a target time period is set, whether the traffic jam road section exists on the route between the site a and the site B is judged according to the acquired data.
Specifically, video data of road elements in the target area range can be collected; the road elements may be lane markings, marking types, etc. in the road, facilities on the road side, such as curbs, railings, rods, traffic signs, etc., or other elements that may affect the driving of the vehicle, such as tide lanes, road maintenance areas, etc., or data of related areas in the notification may be collected according to the notification issued by the traffic department.
Step 102: determining vehicles passing through the target area range in the target time period as target vehicles according to the target area range and the target time period, and generating data acquisition instructions; the data acquisition instruction is used for indicating the target vehicle to upload target data acquired in the target time period through the vehicle-mounted networking equipment and/or the target data acquired in the target area range to the server.
Judging a target vehicle according to vehicle information uploaded to a server by a vehicle; the vehicle information may be positioning information of the vehicle, or other information, which is not limited in this embodiment.
Specifically, for example, a vehicle with an on-vehicle internet access device including a high-precision map application is determined by using positioning information uploaded to a server by the vehicle, and when the vehicle is running, the server collects positioning information of the vehicle on the high-precision map, and can determine a running track of the vehicle according to the positioning information and record a time point of each piece of positioning information. When the server receives the target area range and the target time period, it may be determined which vehicles pass through the target area range within the target time period from the positioning information and the time points of the vehicles collected by the server, that is, the server may determine all vehicles passing through the target area range within the target time period, and may lock the vehicles, as target vehicles in the data collection method of the road information.
And generating a data acquisition instruction by the server according to the selected target area range and the set target time period. After receiving the data acquisition instruction, the target vehicle can retrieve data stored by the target vehicle according to a target area range and/or a target time period in the data acquisition instruction, and because the target vehicle is a vehicle which passes through the target area range in the target time period and is determined by the server, the target vehicle retrieves the target data in the target vehicle according to whether the positioning information of the target vehicle is in the target area range; the target data in the target vehicle can be retrieved by comparing the time of the data stored in the target vehicle with the target time period; or simultaneously retrieving target data in the target vehicle according to the target area range and the target time period. This embodiment does not specifically limit this.
In the region with busy traffic, a plurality of vehicles pass through the target area range simultaneously in the target time period, the vehicles are used as target vehicles for data acquisition, a large amount of data of the target area range can be acquired in a short time, and therefore the acquired data are more comprehensive.
Step 103: sending the data acquisition instruction to the target vehicle to enable the target vehicle to upload the target data to the server.
After the server determines all vehicles passing through the target area range in the target time period, the server sends a data acquisition command containing the target area range and the target time period information to all vehicles passing through the target area range in the target time period; and after receiving the data acquisition instruction, the target vehicle packages and uploads the data to the server according to the target time period in the instruction to finish the data acquisition process.
Specifically, the server may issue the data acquisition instruction to each target vehicle through a long connection mode, where the long connection mode is a connection channel between the server and the vehicle-mounted internet access device, and the data acquisition instruction may be distributed through the long connection mode.
The invention provides a data acquisition method of road information, which comprises the steps of acquiring a target area range and a target time period of data to be acquired; determining vehicles passing through the target area range in the target time period as target vehicles according to the target area range and the target time period, and generating data acquisition instructions; sending the data acquisition instruction to the target vehicle to enable the target vehicle to upload the target data to the server; receiving a data acquisition instruction sent by a server; uploading the target data to the server; when the data of the target area range needs to be acquired, all target vehicles passing through the target area range in the target time period can be called to acquire the data at the same time, the data acquisition speed is greatly increased, and the acquired data volume is increased, so that the acquired data are more comprehensive, and the requirement of quickly and timely updating road information in a high-precision map is met.
Further, on the basis of the above embodiment, according to the data acquisition method for road information provided by the present invention, the generating a data acquisition instruction includes:
acquiring an area range selected by high-precision map application as a target area range; acquiring a time period set by high-precision map application as a target time period;
and generating a data acquisition instruction according to the target time period and the target area range.
The current road information data acquisition process can only be carried out by a single vehicle, and a common vehicle provided with a high-precision map application cannot circle and select the high-precision map and carry out the data acquisition and uploading process. In the application, a program capable of performing circle selection on the high-precision map and a program for processing a data acquisition task are integrated in the high-precision map application installed on a vehicle.
Specifically, the person who determines the target area range and the target time period may be a developer of the high-precision map application, or may be a user of the high-precision map application, which is not specifically limited in this embodiment. When a person needs to collect data of a certain area, directly selecting the area range in an interface of the high-precision map application, and then setting a time period of the needed data; and after the server receives the selected area range and the set time period, taking the area range as a target area range and taking the time period as a target time period, and generating a data acquisition instruction.
For example, a driver a needs to drive to travel from a place a to a place B in 13:00 pm and wants to know a speed limit sign on a road from the place a to the place B before departure, the driver a circles the road from the place a to the place B as a target area range in a high-precision map application, the set time period is 12:50-12:55, the area range and the time period are uploaded to a server, and the server generates a data acquisition instruction according to the target area range (namely, the road from the place a to the place B) and the target time period (namely, 12:50-12: 55).
In the embodiment, the target area range and the target time period included in the data acquisition instruction can be directly set in the interface of the high-precision map application, so that the operation of a user is facilitated, any vehicle can receive and process the data acquisition instruction and upload data, the number of vehicles participating in a data acquisition task is increased, and the acquired data volume is also increased.
Further, on the basis of the above embodiment, according to the data collecting method of road information provided by the present invention, the determining, as a target vehicle, a vehicle that passes through the target area range within the target time period includes:
retrieving historical positioning information of a vehicle, and judging whether the vehicle passes through the target area range in the target time period;
and if the vehicle passes through the target area range in the target time period, determining that the vehicle is the target vehicle.
When the vehicle is driven, the server collects the positioning information of the vehicle on the high-precision map, can determine the driving track of the vehicle according to the positioning information, and records the time point of each positioning information. By retrieving the historical positioning information of the vehicle and the time point of each piece of positioning information, whether the vehicle passes through the target area range within the target time period can be more accurately judged, and therefore the target vehicle is determined.
Furthermore, when the vehicle runs, the positioning information can be continuously uploaded to the server and also can be stored in the vehicle-mounted networking equipment of the vehicle, and the historical positioning information of all vehicles can be retrieved under the condition that the server is not influenced to normally store the current positioning information of the vehicle by retrieving the historical positioning information of the vehicle.
In the embodiment, the target vehicle is determined according to the positioning information of the vehicle, so that whether the vehicle passes through the range of the target area within the target time period can be more accurately judged, and the target vehicle is accurately determined; the retrieval of the historical positioning information does not influence the normal operation of the server.
Further, on the basis of the above embodiment, according to the data collecting method for road information provided by the present invention, after the data collecting instruction is sent to the target vehicle, the method further includes:
and if the target data uploaded by the target vehicle is received, updating the execution state of the data acquisition instruction, and determining that the data acquisition instruction is completely executed.
After receiving a data acquisition instruction, the target vehicle uploads historical video data stored in the vehicle-mounted networking equipment to a server; and after the server receives the data of all the target vehicles, updating the execution state of the data acquisition instruction, updating the execution state from 'executing' to 'execution completed', and determining that the data instruction is executed completely. After detecting that the data instruction is executed, the other processes may perform the next processing on the received data, for example, update the high-precision map according to the received data, or send road condition information to the high-precision map application according to the data content, prompt users, and the like.
In this embodiment, by updating the execution state of the data acquisition execution, other processes in the server may be started, so as to perform more processing on the data.
The following describes a data collection method for road information according to an embodiment of the present invention, with a vehicle-mounted internet device installed in a vehicle as an execution subject.
FIG. 2 is a schematic flow chart of a data collection method for road information at a vehicle end according to another embodiment of the present invention; referring to fig. 2, the data acquisition method for vehicle end road information is applied to a vehicle, where the vehicle is a target vehicle passing through a target area range in a target time period, and further includes:
step 201: receiving a data acquisition instruction sent by a server; the data acquisition instruction is used for indicating the target vehicle to upload target data acquired in the target time period through vehicle-mounted networking equipment and/or the target data acquired in the target area range to the server;
step 202: and acquiring target data acquired in the target time period and/or target data acquired through the target area range according to the data acquisition instruction, and uploading the target data to the server.
The server distributes the data acquisition instructions to each target vehicle in a long connection mode, wherein the target vehicles are vehicles which pass through the target area range within the target time period and are determined by the server according to the positioning data, namely the target vehicles must pass through the target area range within the target time period. Acquiring target data acquired in the target time period and/or target data acquired through the target area range according to the data acquisition instruction, wherein for example, determining the target data according to the target time period, after receiving the data acquisition instruction, a vehicle-mounted networking device in a target vehicle analyzes the data acquisition instruction to acquire the target time period in the data acquisition instruction; according to the target time period, historical data stored in the vehicle-mounted networking equipment can be retrieved, and after the data of the target time period are retrieved, the data are uploaded to the server.
When data are uploaded, especially video data, due to the fact that the data volume is large, a special data uploading line can be used, the data uploading speed is increased, and therefore timeliness of data acquisition is improved.
When the historical data is searched, the data which is stored in the vehicle-mounted networking equipment is used, and the data is searched, so that the normal operation of high-precision map application in the vehicle-mounted networking equipment and the normal storage of the positioning information cannot be influenced.
According to the method and the device, the vehicle-mounted networking equipment in the target vehicle receives the data acquisition instruction and uploads the data, so that the data can be uploaded under the condition that the normal operation of the vehicle-mounted networking equipment is not influenced; data are uploaded by all target vehicles simultaneously, so that the data collection timeliness is improved while the collected data volume is increased.
Further, on the basis of the above embodiment, according to the data acquisition method for road information provided by the present invention, the acquiring target data acquired in the target time period and/or target data acquired via the target area range according to the data acquisition instruction includes:
judging whether a data acquisition task currently running exists in the target vehicle;
if the target data does not exist in the target time period, analyzing the data acquisition instruction, and acquiring the target data acquired in the target time period and/or the target data acquired through the target area range according to the data acquisition instruction;
if the target data exists, the data acquisition instruction is stored, the data acquisition instruction is analyzed after the data acquisition task is finished, and the target data acquired in the target time period and/or the target data acquired through the target area range are/is acquired according to the data acquisition instruction.
For the same vehicle, when a data acquisition task is executed, other data acquisition instructions may be received; therefore, before executing the received data acquisition instruction, whether the data acquisition task is running in the vehicle-mounted networking equipment of the current target vehicle is judged, if the running data acquisition task exists, the newly received data acquisition instruction is stored, the currently running data acquisition task is monitored, and after the current data acquisition task is monitored to be run completely, the newly received data acquisition instruction is analyzed and the new data acquisition task is run.
The operation resources of the vehicle-mounted networking equipment are limited, and when a plurality of data acquisition tasks are processed simultaneously, the processing speed of each task and the normal operation of the vehicle-mounted networking equipment are greatly influenced, so that the data acquisition tasks are processed according to the sequence of received data acquisition instructions, the occupation of operation can be reduced, and the processing speed of the tasks is increased.
In this embodiment, whether the data acquisition task is currently running is determined, so that the processing process of the vehicle-mounted networking equipment on the task is not affected, the data acquisition task is processed in order, and the occupation of the operation resources of the vehicle-mounted networking equipment is reduced.
Further, on the basis of the above embodiment, according to the data acquisition method for road information provided by the present invention, the acquiring target data acquired in the target time period and/or target data acquired via the target area range according to the data acquisition instruction further includes:
retrieving whether target data collected in a target time period and/or target data collected through a target area range are stored in the target vehicle;
if the target data are stored in the target vehicle, uploading the target data;
and if the target data is not stored in the target vehicle, uploading alarm information.
The target vehicles are all vehicles passing through the target area range within the target time period, but after the target time period and/or the target area range in the data acquisition instruction are analyzed, whether the data within the target time period and/or the target area range are stored in the vehicles needs to be retrieved. For example, taking the example of collecting video data, if a camera of a target vehicle fails, when the target vehicle passes through a target area range, the video data of the target area range cannot be acquired.
When data in a target time period and/or a target area range are not stored in the target vehicle, the vehicle-mounted networking equipment uploads warning information to the server, the target vehicle can be informed of the absence of the data to be acquired, and the follow-up server can judge the reason why the target vehicle does not have the data to be acquired according to the warning information and inform a user of the target vehicle.
Furthermore, the vehicle-mounted networking equipment records various data, and can judge whether the various data have the required data types or not through retrieval; the type of the data to be acquired in the data acquisition instruction can be determined manually. For example, two data types, namely point cloud data and video data, are stored in the target vehicle, when the video data need to be collected, whether the video data of the target time period are stored in the target vehicle or not is searched, and if the video data exist, the video data are uploaded.
