Referring to a flow chart of a control method based on an unmanned tour guide vehicle shown in fig. 1, the method specifically comprises the following steps:
step S102, a target navigation route of an area to be visited is obtained, the target navigation route comprises at least one visiting point, and each visiting point is provided with corresponding multimedia information.
Generally, within a region to be visited, a plurality of points to be visited with relative independence, completeness and aesthetic characteristics are divided according to factors such as scene characteristics, region size and the like. In the embodiment, multimedia information in the form of audio, video and the like of each tour point can be recorded in advance, and the multimedia information and the corresponding tour points are bound one by one; the tour point and multimedia information with the unique binding relationship are then stored in the memory of the unmanned vehicle.
The target navigation route may be a preset fixed navigation route corresponding to the tour point, or may be an optimal navigation route planned based on the tour point.
And step S104, controlling the unmanned tour guide vehicle to run along the target navigation route.
In this embodiment, there are various control manners for the unmanned vehicle, such as setting at least one unmanned vehicle in a region to be visited, where each unmanned vehicle corresponds to a target navigation route, and when the unmanned vehicle is started to start working, the unmanned vehicle can travel along the corresponding target navigation route. Alternatively, the instruction can be initiated by the user, so that the unmanned tour guide vehicle is controlled to run along the target navigation route.
And S106, when detecting that the unmanned tour guide vehicle runs to the tour point, controlling a playing device on the unmanned tour guide vehicle to play the multimedia information corresponding to the tour point. The multimedia information includes, for example: text, image, audio, video and the like, and based on different forms of multimedia information, the playing device can be a display screen and an audio, video player and the like.
And in the process that the unmanned tour guide vehicle runs along the target navigation route, detecting whether the unmanned tour guide vehicle runs to the tour point or not in real time, determining the arrived tour point when the unmanned tour guide vehicle is detected to run to the tour point, and controlling a playing device on the unmanned tour guide vehicle to play multimedia information corresponding to the tour point.
The invention provides a control method based on an unmanned tour guide vehicle, which can firstly acquire a target navigation route of an area to be visited, wherein the target navigation route comprises at least one tour point, and each tour point is provided with corresponding multimedia information; and then controlling the unmanned tour guide vehicle to run along the target navigation route, and controlling a playing device on the unmanned tour guide vehicle to play multimedia information corresponding to the tour point when detecting that the unmanned tour guide vehicle runs to the tour point.

For the step S102, the embodiment provides a manner of obtaining a target navigation route of an area to be visited, which may be specifically executed with reference to the following steps:
step one, acquiring at least one tour point needing to be guided in a region to be browsed. The at least one tour point to be guided may be all or part of the tour points within the area to be browsed. In a specific implementation, the tour points that need to be guided can be obtained by the following alternative example.
Example 1: reading a ticket of a user in an image Identification mode, an RFID (Radio Frequency Identification ) mode and other modes to obtain a tour point covered by the ticket; in this case, the sightseeing spot covered by the ticket is taken as the sightseeing spot to be guided in the area to be browsed.
Example 2: and receiving the tour point selection information of the user, thereby obtaining at least one tour point needing to be guided. For example, all the tour points in the region to be browsed are displayed through a display screen of the unmanned tour guide vehicle, so that a user can select the tour points; the user can select the tourist points on the display screen through touch operation, and the unmanned tour guide vehicle receives tourist point selection information and determines at least one tourist point needing to be guided based on the touch operation of the user.
Of course, it should be understood that the above is merely an example description of a way of tour point acquisition and should not be taken as limiting.
And step two, determining a target navigation route reaching at least one tour point according to a preset route planning algorithm.
In consideration of the fact that in practical applications, the current position (which may be understood as the starting point position) of the unmanned tour vehicle and the tour point are not usually the same position, and the tour point may not be limited to one, it is necessary to plan a navigation route from the starting point position and going to at least one tour point, so that the planned navigation route meets the navigation conditions of shortest route, least repeated route, way-designated location (such as a toilet), and the like. It is understood that at least one waypoint in the route planning process is all waypoints determined to need guidance; for example, if it is determined that there is one tour point to be guided, a navigation route from the starting point to the tour point is planned, and if it is determined that there are n (n ≧ 2) tour points to be guided, a navigation route from the starting point to the n tour points is planned.
For the convenience of understanding, the present embodiment describes a method for planning a target navigation route, which is described with reference to the following steps (1) to (3):
and (1) determining a candidate navigation route according to a preset path planning algorithm. During specific implementation, the candidate navigation routes of each tour point starting from the starting point position and guided by the route needed to be guided can be determined according to the path planning algorithms such as the genetic algorithm, the ant colony algorithm, the enumeration method, the simulated annealing algorithm or the particle swarm algorithm. Considering that when the number of the sightseeing points is one, the passable routes between the starting point position and the sightseeing points can be one or more, and when the number of the sightseeing points is more than two, further considering that the sightseeing sequence of each sightseeing point can be various; based on this, the number of the candidate navigation routes in the embodiment is at least one.
The tour order of tour points on different candidate navigation routes and/or the selected passable routes are different, in this case, the route distances, repeated routes, approach places (such as toilets and convenience stores) and other factors corresponding to different candidate navigation routes are different, and in order to meet different requirements of users, the candidate navigation routes can be provided for the users to be flexibly selected.
And (2) when one candidate navigation route is available, determining the candidate navigation route as a target navigation route.
And (3) when the candidate navigation routes are multiple, displaying the candidate navigation routes on a display screen of the unmanned tour guide vehicle. And receiving a route selection result sent by a user based on the plurality of candidate navigation routes, and determining a target navigation route according to the route selection result. The route selection result may be that a target navigation route is directly determined from a plurality of candidate navigation routes; it may also be a filtering condition, such as a filtering condition with the least repeated route, according to which a target navigation route with the least repeated route is determined among the plurality of candidate navigation routes.
In the embodiment, the candidate navigation routes are determined firstly, and then the target navigation route meeting the user requirements (such as few repeated routes and places specified by routes) is selected from the candidate navigation routes, so that multiple choices can be provided for the user, and the user experience is improved.
After the target navigation route is determined according to the mode, the unmanned tour guide vehicle can be controlled to run along the target navigation route. In order to improve the control flexibility of the unmanned tour guide vehicle, the following two implementation modes for controlling the unmanned tour guide vehicle to run along the target navigation route are provided.
The control method is as follows:
firstly, at least one unmanned guide vehicle is arranged in an area to be visited, and each unmanned guide vehicle is correspondingly provided with at least one target navigation route for running. Different target navigation routes can be navigation routes of the same tour point and different tour orders, for example, for A, B, C, D four tour points, according to different tour orders, the target navigation route can be A-B-C-D or B-A-D-C; the different target navigation route may also be a navigation route of different waypoints, for example, waypoint A, B, C, D is included on target navigation route I and waypoint B, E, F is included on target navigation route II.
Then, controlling the unmanned tour guide vehicle to run along the target navigation route according to the running information by setting the running information of the unmanned tour guide vehicle; the driving information may include, but is not limited to, at least one of: the method comprises the following steps of running sequence of different target navigation routes, circulating running times along the target navigation routes, starting time of each circulating running, time interval of two adjacent circulating running, stay time of each tour point and running speed. The driving information can be flexibly set according to the annual busy season, the daily pedestrian volume, the tour characteristics of tour points, the service life of the unmanned tour guide vehicle and other factors, so as to better meet the actual application scene. For example, in one possible scenario, the travel information for an unmanned tour guide vehicle is set to: the driving sequence is the target navigation route I, II, and taking the target navigation route I as an example, the corresponding driving information may further include: the running speed is 5km/h, the starting time of the first cycle running along the target navigation route I is 8 points, the cycle running times are 5 times, and the time interval of the cycle running is 5 minutes, namely when the unmanned tour guide vehicle finishes one round of running along the target navigation route I, the unmanned tour guide vehicle stops working for 5 minutes and then starts the next round of running along the target navigation route I; the stay time of the tour point A, B, C on the target navigation route I is 3 minutes, 8 minutes and 5 minutes, and the stay time is related to the display time of the multimedia information corresponding to the tour point. After the unmanned tour guide vehicle finishes driving along the target navigation route I according to the driving information, the unmanned tour guide vehicle can start to continue driving along the target navigation route II according to the driving information corresponding to the target navigation route II.
In the first control mode, the unmanned tour guide vehicle can be automatically controlled to run along the target navigation route according to the preset target navigation route running and running information, so that the control process of the unmanned tour guide vehicle is very simple and convenient.
And a second control mode:
in order to facilitate the use of the unmanned guided vehicle by the user, the present embodiment may further release the unmanned guided vehicle controlled by the user in the area to be visited, and based on this, the process of controlling the unmanned guided vehicle to travel along the target navigation route may include the following steps i to iii:
and step i, receiving an unlocking instruction of a user, and executing an unlocking operation based on the unlocking instruction.
In the embodiment, the unmanned tour guide vehicle can be parked at a fixed parking point and can also freely run in the area to be visited; when a user wants to control the unmanned tour guide vehicle, the user can send out unlocking instructions in various forms such as voice, buttons, code scanning, touch screen operation and the like. And the unmanned tour guide vehicle executes unlocking operation according to the unlocking instruction of the user, namely, the user is granted the permission to use the unmanned tour guide vehicle.
And step ii, receiving a driving control instruction of the user, and executing the driving control operation based on the driving control instruction. The travel control command is a command for controlling travel information such as a travel speed, a start, a stop, a stay time period, and the like of the unmanned guide vehicle, based on which the travel control operation is an operation for setting the travel information. In the embodiment, the driving control instruction can improve the flexibility of controlling the unmanned tour guide vehicle by the user and meet the individual requirements of the user; for example, when the user wants to stay at a certain tour point for a while, the user can initiate a driving control instruction for stopping driving, so that the unmanned tour guide vehicle stops driving and continues driving after receiving the driving control instruction for the user to continue driving; for example, the running speed of the unmanned tour guide vehicle is controlled to match the tour speed of the user through a running control command of the speed, so that the situation that the running speed of the unmanned tour guide vehicle is too high or too low is avoided.
And step iii, controlling the unmanned tour guide vehicle to travel along the target navigation route based on the unlocking instruction and/or the travel control operation.
In a possible implementation manner, after the unmanned tour guide vehicle executes the unlocking operation, the unmanned tour guide vehicle is controlled to run along the target navigation route according to preset default running information; under the condition, the user does not need to operate too much, only the unmanned tour guide vehicle needs to be driven, the tour process is labor-saving, and the tour guide vehicle is particularly suitable for the old.
In another possible implementation manner, in order to improve the convenience of the user, it may not be necessary to execute an unlocking instruction, or it may be determined that the usage right of the unmanned tour guide vehicle is unlocked in step (3), that is, when the target navigation route is determined among the plurality of candidate navigation routes. Based on this, it is possible to determine the travel information after the unmanned guide vehicle performs the travel control operation, and control the unmanned guide vehicle to travel along the target navigation route in accordance with the travel information.
Of course, in practical applications, the unmanned tour guide vehicle may be controlled to travel along the target navigation route based on the unlocking instruction and the travel control operation at the same time, including: after the unmanned tour guide vehicle executes unlocking operation, the user is granted the authority to use and control the unmanned tour guide vehicle, then the driving information is determined according to the driving control operation, and finally the unmanned tour guide vehicle is controlled to drive along the target navigation route according to the driving information.
In the second control mode, the driving of the unmanned tour guide vehicle can be better controlled according to the unlocking instruction and the driving control instruction of the user, the humanized service of the unmanned tour guide vehicle is improved, the diversity requirements of different user groups are met, and the user experience can be obviously improved.
Therefore, the automatic control mode and the manual control mode of the unmanned tour guide vehicle can save the tour guide labor cost and improve the tour guide efficiency, benefit and image of tour areas such as scenic spots, museums and the like.
Next, in the process of driving the unmanned guided vehicle along the target navigation route, the embodiment proposes an implementation method for detecting that the unmanned guided vehicle drives to the tour point, and refers to the following two steps:
firstly, acquiring area indication information of an unmanned tour guide vehicle in the running process of the unmanned tour guide vehicle; wherein the area indication information includes at least one of: vehicle positioning information and tour route images.
In particular implementations, vehicle positioning information for an unmanned tour guide vehicle may be collected via a positioning device. The Positioning device adopts Positioning technologies such as a Global Positioning System (GPS) and an Ultra Wide Band (UWB) to acquire vehicle Positioning information of the current unmanned guide vehicle in an area to be visited. And the image of the tour route can be collected through the image collecting device arranged on the unmanned tour guide vehicle. Along with the running of the unmanned tour guide vehicle along the target navigation route, the image acquisition equipment can acquire images along the route according to a preset time interval (such as 5 seconds), namely the tour route image is obtained; or the image acquisition equipment can acquire videos along the way in a video acquisition mode and acquire tour route images based on the video frames.
In addition, the positioning device and the image acquisition device can be devices inside the unmanned tour guide vehicle body or independent devices outside the unmanned tour guide vehicle.
And secondly, determining that the unmanned tour guide vehicle runs to the tour point by comparing the area indication information with the position identification information of the tour point.
It is to be understood that the area indication information for comparison corresponds to the location identification information of the waypoint, and when the area indication information includes the vehicle positioning information, the corresponding location identification information includes the waypoint location area. In the case of an electronic map, a tour point is usually an area covering a certain geographical area and is marked by a designated location point. In this case, the tour point position area may be all areas covered by the tour point, or may be a preset area determined by taking the designated position point as a reference and combining with the real geographic environment of the tour point, such as a circular area with the designated position point as a center of a circle, a sector area with the designated position point as a vertex, and the like.
By comparing the vehicle positioning information with the region of the tourist site, the implementation process of determining that the unmanned tour guide vehicle runs to the tourist site comprises the following steps: comparing the vehicle positioning information with the position area of the tourist spot; and when the comparison result shows that the vehicle positioning information is located in the tour point position area, determining that the unmanned tour guide vehicle runs to the tour point. In specific implementation, when the vehicle positioning information collected in real time enters a certain tourist spot position area, the name of the tourist spot where the unmanned tour guide vehicle travels to and arrives at is determined. In this case, the playing device on the unmanned vehicle can be directly controlled to play the multimedia information corresponding to the tour point. Or generating play reminding information in the form of characters, voice, pictures and the like, wherein the play reminding information is used for reminding a user whether to play the multimedia information and/or is used for reminding the user to select a play mode (such as voice play, video play, picture display and character description) of the multimedia information; for example, the play reminding information is: "you have arrived at the X tour point, play multimedia information", "yes", "no", "play with 5 minutes delay", "play multimedia information with voice", and so on. The user can freely control the playing time and the playing mode of the multimedia information according to the own tour habit; and then when a determined playing instruction of the user is received, controlling a playing device on the unmanned tour guide vehicle to play the multimedia information corresponding to the tour point according to the playing time and the playing mode determined by the user.
In another scenario, the area indication information includes a tour route image, and the corresponding location identification information includes a marker image of a tour point. Most tourist sites have unique markers such as towers, bridges, sculptures, signs and the like, so that images of the markers can be collected as position identification information of the tourist sites.
