[0052] An embodiment of the present application provides a vehicle guidance method, as Figure 1 shown, including:

[0053] Step S101: Identify a target vehicle currently to enter a target factory area to obtain vehicle information of the target vehicle;

[0054] In the specific implementation of this step, image data of the target vehicle currently to enter the target factory area is acquired; the image data is subjected to image recognition to obtain vehicle information corresponding to the image data; the vehicle information includes information such as license plate number, vehicle type, owner information, vehicle status information, etc. License plate recognition (LPR) and other technologies can also be used to recognize the license plate number to obtain the vehicle information of the target vehicle.

[0055] Step S102: Query pre - stored vehicle information in a preset database based on the vehicle information to obtain a query result;

[0056] In the specific implementation process of this step, a preset database query statement is used to query the vehicle number field of the preset database based on the vehicle number of the vehicle information, and the return matching result of the preset database is received. The return matching result includes the pre-stored information of the target vehicle corresponding to the vehicle information; or the return matching result is that no pre-stored information of the target vehicle corresponding to the vehicle information is found.

[0057] Step S103: When the query result is that there is pre-stored information of the target vehicle corresponding to the identification information in the preset database, plan the path of the target vehicle based on the target unloading point and the current vehicle running state in the pre-stored information of the vehicle to obtain a guiding path.

[0058] In the specific implementation process of this step, obtain the preset road network structure of the target area; configure the current position of the target vehicle as the starting point of the path and the target unloading point as the end point of the path; plan the path of the target vehicle based on the preset road network structure, the road condition information of each path in the preset road network structure, the road attribute information, and the current vehicle running state to obtain a guiding path.

[0059] Step S104: Guide the target vehicle to the target unloading point based on the guiding path.

[0060] In the specific implementation process of this step, the guiding device at the starting point of the path guides the running direction of the target vehicle according to the first target alternative road section, and prompts the target vehicle to drive to the first path node; when the target vehicle travels to the monitoring area of the guiding device corresponding to the first path node, the guiding device at the first path node receives the pre-stored information of the target vehicle and the guiding path of the target vehicle; the guiding device at the first path node guides the running direction of the target vehicle according to the guiding path, and prompts the target vehicle to drive to the next path node until the target vehicle is guided to the target unloading point.

[0061] This application identifies the target vehicle currently to enter the target factory area to obtain the vehicle information of the target vehicle; queries the pre-stored information of each vehicle in the preset database based on the vehicle information to obtain a query result; when the query result is that there is pre-stored information of the target vehicle corresponding to the vehicle information in the preset database, plan the path of the target vehicle based on the target unloading point and the current vehicle running state in the pre-stored information of the vehicle to obtain a guiding path; guide the target vehicle to the target unloading point based on the guiding path. The method of this application can be applied to factories with unattended points, saving manpower and material resources.

[0062] Another embodiment of this application provides another vehicle guiding method, asFigure 2 As shown in

[0063] Step S201: Identify the target vehicle that is about to enter the target factory area currently, and obtain the vehicle information of the target vehicle;

[0064] In the specific implementation process of this step, image data of the target vehicle that is about to enter the target factory area currently is acquired; image recognition is performed on the image data to obtain vehicle information corresponding to the image data; the vehicle information includes information such as license plate number, vehicle type, owner information, and vehicle status information. Technologies such as license plate recognition (LPR) can also be used to recognize the license plate number to obtain the vehicle information of the target vehicle. The vehicle should be reported in advance before entering the factory, and the reported data enters the preset database of the target factory area. When the vehicle travels from the road outside the target factory area to the gate for inspection, the guiding device at the gate recognizes the vehicle information of the vehicle and compares it with the pre-stored vehicle information in the database. If the vehicle information matches, the gate barrier is automatically opened for release, and the vehicle driving direction and the destination unloading location are guided by voice according to the pre-stored vehicle information. Otherwise, the vehicle driver can report on-site to enter the vehicle information into the database.

[0065] Step S202: Query each pre-stored vehicle information in the preset database based on the vehicle information to obtain a query result;

[0066] In the specific implementation process of this step, the vehicle number field of the preset database is queried based on the vehicle number of the vehicle information using a preset database query statement, and the returned matching result of the preset database is received. The returned matching result includes the pre-stored vehicle information corresponding to the vehicle information; or the returned matching result is that no pre-stored vehicle information corresponding to the vehicle information is found. When the query result is that the preset database does not include the pre-stored vehicle information corresponding to the identification information, the vehicle operator is prompted by voice to report the vehicle on-site.

[0067] Step S203: Obtain the preset road network structure of the target area;

[0068] In the specific implementation process of this step, the preset road network structure is configured according to the road distribution of the target factory area; the preset road network structure includes the layout and connection of the internal roads of the target factory area. Each node in the road network represents the location of the guiding device, and the guiding device can be configured on a telegraph pole or a wall. Each edge of the preset road network structure represents a road section, and the actual road layout of the target factory area is transformed into a preset road network structure composed of nodes and edges.

[0069] Step S204: Configure the current position of the target vehicle as the starting point of the path and configure the target unloading point as the ending point of the path;

[0070] In the specific implementation process of this step, the path start point and the path end point of the target vehicle are respectively added to the preset road network structure as the start point and the end point of path planning. The path start point can be the current position of the target vehicle, and the path end point is the target unloading point of the target vehicle.

[0071] Step S205: Plan the path of the target vehicle based on the preset road network structure, the road condition information of each path in the preset road network structure, the road attribute information, and the current vehicle operation state to obtain a guiding path.

[0072] In the specific implementation process of this step, a path information set and a relevant road section information set between the path start point and the path end point are constructed. The relevant road section set includes each relevant path node and each relevant road section. Based on the path start point, the path end point, the real-time road section parameters of each relevant road section, and the current vehicle operation state, relevant path nodes and relevant road sections are screened from the relevant road section information set to obtain each target relevant path node and each target relevant road section. The real-time road section parameters include real-time road condition information and the road attribute information of each relevant road section. Based on the path start point and the current vehicle running direction, each first alternative road section for the current vehicle running is determined. Through calculation and processing based on the real-time road section parameters of each first alternative road section, the weight value corresponding to each first alternative road section is obtained. Based on each weight value, each first alternative road section is screened to obtain a first target alternative road section and a first path node running along the first target alternative road section. The first path node is used as the path start point to screen the next target alternative road section, and the loop iteration is carried out until the path end point is screened, so as to obtain each target relevant path node and each target relevant road section. Specifically, first, a path information set S is constructed, and the path start point is added to S. Then, all relevant road sections between the path start point and the path end point of the target vehicle are taken to construct a set U. The edges corresponding to all relevant road sections and all nodes associated with the relevant road sections are added to U to obtain each target relevant path node and each target relevant road section. According to the road condition information and the road attribute information, the weight of each alternative edge is calculated. The weight calculation may involve multiple factors, such as driving time, road congestion condition, vehicle speed limit, etc. For each relevant path node, the relevant road section corresponding to the minimum weight value is selected and added to S until both the path start point and the path end point of the vehicle are included in S. Based on each target relevant path node and each target relevant road section, the path information set is updated to obtain the guiding path.

[0073] Step S206: Guide the target vehicle to the target unloading point based on the guiding path.

[0074] In the specific implementation process of this step, specifically, the guidance device at the starting point of the path guides the running direction of the target vehicle according to the first target alternative road section, prompting the target vehicle to drive to the first path node; when the target vehicle drives to the monitoring area of ​​the guidance device corresponding to the first path node, the guidance device of the first path node receives the target vehicle pre-stored information and the guidance path of the target vehicle; the guidance device of the first path node guides the running direction of the target vehicle according to the guidance path, prompting the target vehicle to drive to the next path node until the target vehicle is guided to the target unloading point. The guidance device is mainly composed of an edge controller, an infrared camera, a loudspeaker and a communication module; the edge controller is used to determine the vehicle information and issue guidance instructions according to the vehicle information; the infrared camera is used to identify the license plate and monitor the vehicle's walking trajectory; the loudspeaker is used to convey the guidance instructions to the truck driver; the communication module is used to obtain the information of the previous guidance device and pass the vehicle information and the target unloading point to the next guidance device. When the vehicle enters, the camera on the vehicle guidance device identifies the vehicle. If the vehicle has been reported, the gate is automatically opened to release it. Otherwise, the vehicle driver needs to report on the spot before it is allowed to be released. After the vehicle is released, it is guided to the next destination by the vehicle guidance equipment, and this process is repeated until the vehicle reaches the target unloading point. After the vehicle has completed unloading, the vehicle guidance equipment guides the vehicle out of the factory.

[0075] Step S207: Identify the running state of the target vehicle to obtain an identification result;

[0076] In the specific implementation process of this step, the cargo unloading image of the target vehicle is acquired in real time, and a judgment is made based on the cargo unloading image to obtain a judgment result. When the judgment result is that the cargo unloading of the target vehicle is completed, the recognition result that the target vehicle has completed the unloading operation is obtained; when the judgment result is that the cargo unloading of the target vehicle is not completed, the recognition result that the target vehicle is in the process of unloading is obtained. The image recognition model can be trained using a deep learning algorithm to enable it to automatically identify key features in the unloading process, such as reduced cargo, empty cargo box, etc., so as to determine whether the unloading is completed.

[0077] Step S208: When the recognition result indicates that the target vehicle has completed the unloading operation, a voice prompt is given to the target vehicle to guide the target vehicle to leave the target factory area.

[0078] In the specific implementation process of this step, when the recognition result indicates that the target vehicle has completed the unloading operation, the pre-recorded voice information is broadcast to give a voice prompt to the target vehicle, guiding the target vehicle to leave the target factory area. For example, playing voice content such as "Please note that your vehicle has completed the unloading operation. Please prepare to leave this factory area. Thank you for your cooperation!" is clear and polite, which helps to guide the driver to act.

[0079] In this application, the target vehicle to be driven into the target factory area is recognized to obtain the vehicle information of the target vehicle; based on the vehicle information, the pre-stored information of each vehicle in the preset database is queried to obtain a query result; when the query result indicates that there is target vehicle pre-stored information corresponding to the vehicle information in the preset database, the path of the target vehicle is planned based on the target unloading point and the current vehicle running state in the target vehicle pre-stored information to obtain a guiding path; the target vehicle is guided to the target unloading point based on the guiding path.
