The map tour mode is that when a map tour is performed, whether the map tour is performed by the unmanned aerial vehicle or the unmanned vehicle can be set, and of course, the map tour mode can also be realized by the robot, but the map tour mode is not limited to this, and those skilled in the art can specifically set the map tour mode according to actual conditions.
The map tour parameters refer to a set of tour parameters set during map tour, and may also include parameters corresponding to a camera during tour.
It should be noted that, for different map tour modes, corresponding map tour parameters are respectively set, and for example, in the map tour process of the unmanned aerial vehicle, the corresponding tour angle has a large influence on the visible range on the map display interface at the next moment, so that a proper tour angle should be set according to different map tour modes and the current map data, so that the most complete tour map scene can be displayed for the user, and the experience of the user is improved.
S22: and starting the map tour based on the map tour rule.
Specifically, a corresponding map tour route is obtained according to the initial position and the target position, corresponding map tour parameters are respectively determined according to different determined map tour modes, and after the map tour route, the map tour mode and the corresponding map tour parameters are obtained, map tour is started according to the map tour route, the map tour mode and the corresponding map tour parameters.

As shown in fig. 2, for the map display interface at the current time, the fixed point location 1 framed by the mark frame is taken as the preset central point of the map display interface, and the preset central point is determined by the map tour starting position, that is, when the map tour path is obtained, the starting position is taken as the preset central point of the map display interface, and then the preset threshold is determined according to the preset central point and the size of the map display interface, that is, the distance from the preset central point to the map display interface may be taken as the preset threshold, that is, the preset threshold is d1, and according to the actual situation, for example, the size of d1 is determined to be 3 km, but not limited thereto, the present disclosure has no specific limitations, and those skilled in the art can specifically set the preset threshold according to the actual situation.
The preset time refers to a time at which the map data needs to be loaded and the corresponding visual map range is displayed on the map display interface at the next time as time goes on based on the current time, and the preset time may be, for example, 1 second, but is not limited thereto, and those skilled in the art may specifically set the preset time according to actual situations.
It should be noted that, in the process of map tour, the starting position is used as the preset central point of the map display interface, when the second map data at the next preset time, that is, the next second is obtained, the preset central point is not changed, only the range of the visual map to be displayed on the map display interface is changed, that is, the preset central point is not changed, and according to the obtained map tour path, that is, a plurality of fixed point locations on the map display interface, at the next preset time, the next fixed point location is used as the preset central point on the map display interface, and the visual map range on the map display interface at the next preset time is changed correspondingly.
Specifically, under the condition that map tour is started, second map data which needs to be loaded within the next preset time is determined according to a preset threshold and the map data at the current time, and the second map data is loaded.
For example, as shown in fig. 2, for a fixed point location 1, a fixed point location 2, and a preset threshold, and taking the fixed point location 1 as a preset central point corresponding to an initial position, since the preset central point is not changed, according to an obtained map tour path, that is, a plurality of fixed point locations on a map display interface, at a next preset time, taking the fixed point location 2 as the preset central point of the map display interface, the map display interface may display a visible map range at the next time to a user according to the loaded second map data, but is not limited thereto, and a person skilled in the art may specifically set the preset central point according to actual conditions.

It should be noted that, because the map display interface is limited, in the process of map tour, when a visual map range that needs to be displayed at the next preset time is displayed to the user on the map display interface, the first map data that corresponds to the visual map range that needs to be displayed at the next preset time in the map display interface at the current time and does not need to be displayed at the next preset time is determined according to the corresponding second map data that corresponds to the visual map range that needs to be displayed at the next preset time.
Specifically, when map data of a current time is acquired under the condition that map tour is started, first map data is determined in the map data of the current time, and the first map data is deleted as the first map data is already displayed and does not need to be displayed at the next time.
On the basis of the above embodiments, in some embodiments of the present disclosure, one execution manner of S12 may be:
the size of the second map data is acquired.
Based on the size of the second map data, the first map data is deleted.
For example, the size of the second map data may be obtained according to the size of the second map data corresponding to the range of the visual map displayed at the next preset time in the map display interface, and since the size of the map display interface is limited, in order to ensure that the second map data corresponding to the range of the visual map displayed at the next preset time can be displayed, the corresponding first map data is deleted according to the size of the second map data, and the size of the first map data is the same as the size of the second map data.

5. The method according to claim 1, wherein the determining the second map data corresponding to the next preset time based on a preset threshold and loading the second map data comprises:
judging whether the map data corresponding to the map tour at the next preset moment is three-dimensional map data or not based on a preset threshold and the map data at the current moment;
if yes, loading the three-dimensional map data; or
And if not, loading the two-dimensional map data.
6. The method of claim 1, wherein the deleting the first map data upon determining that the first map data exists in the map data comprises:
acquiring the size of the second map data;
deleting the first map data based on a size of the second map data.
7. The method of claim 1, further comprising:
when determining that the preset central point at the current moment has associated equipment, acquiring data information corresponding to the associated equipment, wherein the preset central point is determined by the starting point of the map tour route, and the associated equipment at least comprises an infrared sensor, a camera and an ultrasonic sensor.
8. A map tour device based on data management is characterized by comprising:
the map data acquisition module is used for acquiring map data in a preset memory when map tour is started, wherein the map data is loaded at the current moment;
the map data acquisition module is further configured to determine second map data corresponding to a next preset time based on a preset threshold and the map data at the current time when the map tour is started, and load the second map data, wherein the preset threshold is determined according to a preset central point of a map display interface and the size of the map display interface, and the preset central point is an initial position of a map tour path;
the deleting module is used for deleting the first map data when the first map data exists in the map data;
the first map data is determined according to second map data, and the second map data is map data loaded at the next preset time in the map tour process.
9. An electronic device, comprising:
one or more processors;
a storage device to store one or more programs,
when executed by the one or more processors, cause the one or more processors to implement the data management-based map tour method of any one of claims 1 to 7.
10. A computer-readable storage medium, on which a computer program is stored, which, when being executed by a processor, implements a data management-based map tour method according to any one of claims 1 to 7.
