Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides a method for displaying a map object, please refer to fig. 1, which shows a flow diagram of the method, and may include:
step S101: the target display reference value of the map object is determined by the area of the first target area in the map and the number of map objects in the most dense area in the map.
Wherein the first target area may be, but is not limited to, an area manually selected by a user. It should be noted that, ideally, the first target area is an area where the map objects are most densely distributed. This step is to ensure that the map objects in the most dense areas can be displayed on the map without overlapping each other by determining the target display reference value, and it can be understood that if the map objects in the most dense areas can be displayed on the map without overlapping each other, the map objects in the non-most dense areas can be displayed on the map without overlapping each other.
In one possible implementation, determining a target display reference value of a map object by an area of a first target region in a map and a number of map objects in a most dense region in the map includes:
(1) and calculating a display reference value of the map object as a display reference calculation value by the area of the first target area in the map and the number of the map objects in the most dense area in the map.
Specifically, at the current scale, the area S1 of the first target area in the map is divided by the number N1 of map objects in the most dense area to obtain a display reference calculation value S', that is:
S′＝S1/N1 (1)
(2a) and if the display reference calculation value is smaller than the preset minimum display value, determining the preset minimum display value as a target display reference value.
The preset minimum display value may be a minimum value of a display area of the map object.
Assuming that the target display reference value is S and the preset minimum display value is S _ MIN, if S' < S _ MIN, S is equal to S _ MIN.
(2b) If the display reference calculation value is larger than the preset maximum display value, determining the preset maximum display value as a target display reference value;
the preset maximum display value may be a maximum value of a display area of the map object.
Assuming that the target display reference value is S and the preset maximum display value is S _ MAX, if S' > S _ MAX, S is S _ MAX.
(2c) And if the display reference calculation value is greater than or equal to the preset minimum display value and is less than or equal to the preset maximum display value, determining the display reference calculation value as a target display reference value.
That is, if S _ MIN < ═ S '< ═ S _ MAX, S is S'.
Step S102: determining a display value of the target map object in the second target area as a target display value based on the target display reference value, the number of map objects in the most dense area, and the number of target map objects in the second target area.
The second target area is the same as or different from the first target area, and may be any display area in the map, and the target display value is used to represent the display size of the target map object in the second target area. The target map objects in the second target area may be map objects of the same attribute.
In one possible implementation, the process of determining a display value of a map object in the second target area as the target display value according to the target display reference value, the number of map objects in the most dense area, and the number of target map objects in the second target area may include:
(1) the display value of the target map object in the second target area is calculated as a target display calculation value by the target display reference value, the number of map objects in the most dense area, and the number of target map objects in the second target area.
Specifically, the display value of the target map object in the second target area may be calculated as the target display calculation value S _ V' by the target display reference value S, the number N1 of map objects in the most dense area, and the number N2 of target map objects in the second target area, using the following formula:
S_V′＝S*(N1/N2) (2)
(2a) and when the target display calculation value is larger than the preset maximum display value, determining the preset maximum display value as the target display value.
That is, if S _ V' > S _ MAX, target display value S _ V is equal to S _ MAX.
(2b) And when the target display calculation value is smaller than the target display reference value, determining the target display reference value as the target display value.
That is, if S _ V' < S, target display value S _ V becomes S.
(2c) And when the target display calculation value is greater than or equal to the target display reference value and is less than or equal to the preset maximum display value, determining the target display calculation value as the target display value.
That is, when S < ═ S _ V '< ═ S _ MAX, target display value S _ V is S _ V'.
Step S103: and displaying the target map object in the second target area according to the target display value.
The above process makes the displayed target map objects smaller when the density of the target map objects in the second display area is higher, whereas the displayed target map objects are smaller when the density of the target map objects in the second display area is lower, that is, when the density of the target map objects changes, the display size of the target map objects changes accordingly. Referring to fig. 2, an effect diagram of the method provided by the embodiment of the present invention is shown, where a plurality of interphone icons carried by security personnel are densely distributed on a map, and when the icon density changes, the size of the icon changes, in an actual scene, patrol of the security personnel is dynamic, and the position of each icon changes constantly, and the embodiment of the present invention can dynamically change the size of the icon according to the density change.
The map object display method provided by the embodiment of the invention determines a target display reference value of a map object according to the area of a first target area in a map and the number of map objects in the most dense area in the map, then determines a display value of the target map object in a second target area as a target display value according to the target display reference value, the number of map objects in the most dense area and the number of target map objects in the second target area, and finally displays the target map object in the second target area based on the target display value. The map object display method provided by the embodiment of the invention can better solve the problem of mutual coverage when the map objects in the map are displayed, so that a user can visually and comprehensively see the distribution density of the map objects, thereby facilitating the overall arrangement of the objects.
In view of the above, the present invention provides another method for displaying a map object, and please refer to fig. 2, which shows a flowchart of a method for displaying a map object, where the method may include:
step S301: the target display reference value of the map object is determined by the area of the first target region in the map and the number of map objects in the most dense region in the map.
Step S302: the display value of the target map object in the second target region is determined as the target display value based on the target display reference value, the number of map objects in the most dense region, and the number of target map objects in the second target region.
The second target area is the same as or different from the first target area, and the target display value is used for representing the display size of the map object in the second target area.
Step S303: and displaying the target map object in the second target area according to the target display value.
It should be noted that the specific implementation process of steps S301 to S303 is the same as the specific implementation process of steps S101 to S103 in the foregoing embodiment, and the specific implementation process of the steps may refer to the foregoing embodiment, which is not described herein again.
Step S304: whether a target display area in which a plurality of target map objects are simultaneously displayed exists in the second target area is detected.
In a possible implementation manner, the display area of the map may be uniformly divided into grids in advance, and the size of the grids is matched with the preset minimum display value, when the target display area is determined, whether a grid in which a plurality of target map objects are simultaneously displayed exists may be detected, and if a grid in which a plurality of target map objects are simultaneously displayed exists, the grid in which a plurality of target map objects are simultaneously displayed is determined as the target display area. It should be noted that, if multiple map objects are located in the same grid, it indicates that the GPS positions reported by the devices corresponding to the multiple map objects fall in the same grid.
Step S305: if the second target area has a target display area, rotating one or more of the plurality of target map objects displayed simultaneously in the target display area so that the plurality of target map objects do not overlap with each other.
It can be understood that when the GPS positions reported by the devices corresponding to the map objects fall on the same grid, the map objects in the grid overlap with each other, and at this time, in order to enable the user to visually see the distribution of the map objects, the map objects that overlap with each other need to be made non-overlapping.
In one possible implementation, the process of rotating one or more of the plurality of target map objects simultaneously displayed at the target display area may include: determining a rotation angle based on the number of target map objects displayed in the target display area; one or more of the plurality of target map objects are rotated according to the rotation angle.
Further, the rotation angle P may be determined by the number of target map objects displayed in the target display area N3 using the following equation:
P＝2*π/(N3+Z)
wherein pi is a circumferential rate, and Z is a set complementary coefficient which is an integer.
When the map objects are rotated, all the map objects may be rotated based on the specified rotation angle P, or some of the map objects may be rotated, for example, three map objects are displayed simultaneously on a certain mesh, and the three map objects overlap with each other, and when the three map objects are rotated, the three map objects may be rotated simultaneously, for example, the calculated rotation angle P is 30 degrees, and the three map objects may be rotated by 30 degrees, 60 degrees, and 90 degrees, respectively, with reference to the positions of the three map objects, or one of the map objects may be fixed, and the other two map objects may be rotated, for example, by 60 degrees, and the other two map objects may be rotated by 60 degrees and 120 degrees, respectively, with reference to the fixed map object. The specific rotation manner is not limited in this embodiment, and no matter how the rotation is performed, it is sufficient that the plurality of map objects are not overlapped with each other after the rotation. Referring to fig. 4, the lower left corner of fig. 3 shows the effect diagram of three overlapped map objects after rotation.
The method for displaying a map object according to an embodiment of the present invention includes determining a target display reference value of a map object according to an area of a first target area in a map and a number of map objects in a most dense area in the map, determining a display value of a target map object in a second target area as a target display value according to the target display reference value, the number of map objects in the most dense area, and the number of target map objects in the second target area, and finally displaying the target map object in the second target area based on the target display value, which can better solve a problem of overlapping of the map objects when displaying the map object in the map, and in view of a situation that a certain target display area may display a plurality of target map objects simultaneously, the embodiment further rotates one or more of the plurality of target map objects simultaneously displayed in the target display area, the plurality of mutually overlapped map objects are not mutually overlapped, so that a user can visually and comprehensively see the distribution density of the map objects, and the objects are conveniently arranged in a lump.
