The display method provided by the present invention is described in detail below with reference to several embodiments.
Fig. 4 is a flowchart of a display method according to a first embodiment of the present invention. The execution main body of the display method provided by the embodiment of the present invention may be the display device provided by the embodiment of the present invention, and the display device may be implemented in any software and/or hardware manner, where the display device may be integrated in a display system, or may also be independently configured.
The display device may be, for example, a smart phone, a portable electronic device, a computer, a server, or the like, or may be a part of the above-mentioned device. In this embodiment, the details will be described by taking an execution main body as an example of a display device.
As shown in fig. 4, the method of the present embodiment includes:
s401, obtaining a network data packet.
The network data packet may include information such as location information and attribute information corresponding to one or more target objects in the target area. The network data packet may include location information and attribute information corresponding to one target object in the target area, or may include location information and attribute information corresponding to a plurality of target objects in the target area, respectively.
For example, the position information corresponding to the target object may be latitude and longitude information, and the position information may be obtained by a positioning module (or may also be referred to as a position sensor) of the target object, for example, the positioning module may be a Global Positioning System (GPS) module, or may also be another module capable of obtaining the position information of the target object, which is not limited in this embodiment of the present invention. The display device can determine the display position of each graphic element in the display style of the target object in the display interface according to the position information respectively corresponding to the target object.
For example, the attribute information corresponding to the target object may be an object category attribute, a focus attribute, and the like. The object type attribute is used for indicating the type of the target object; in practical applications, the object type and the importance level of all the target objects in the display system may be set in advance, and when the target object sends data to the network device, the information of the object type and/or the importance level (the importance attribute) to which the target object belongs is also sent to the network device. In this scheme, the attribute information of the target object may be used to determine the type of the primitive, the number of primitives, and the attribute value of the primitive included in the display style thereof.
According to a possible implementation manner, a target object in a target area sends data such as position information, attribute information and other state information of the target object to network equipment, the network equipment can process and cache the received data, and a display device can acquire the position information, the attribute information and other state information corresponding to one or more target objects in the target area from the network equipment.
Other state information of the target object referred to herein may include, for example, speed information, pose information, whether a fault has occurred, and the like of the target object. Of course, other state information of the target object in the embodiment of the present invention is not limited to the foregoing example, and may also include other state information.
S402, judging whether the target object appears for the first time according to the network data packet.
For each target object included in the network data packet, the display device determines whether the target object appears for the first time, and if it is determined that the target object appears for the first time, S403 is performed, and if it is determined that the target object does not appear for the first time, S403' is performed.
In a possible implementation manner, the attribute information corresponding to the target object includes an identity corresponding to the target object, the display device matches the identity corresponding to the target object with an identity of a displayed target object, if the matching is not successful, it is determined that the target object appears for the first time, and a corresponding display style is created for the first-appearing target object, that is, S403 is executed; if the matching is successful, it is determined that the target object and the displayed target object which is successfully matched are the same object, and then the state of the target object in the display interface is updated according to the data in the network data packet without recreating a corresponding display style for the target object, that is, S403' is executed.
For example, the identity corresponding to the target object may be an identity ID of the target object, or an equipment number, or may also be other identity of the target object.
And S403, determining and configuring the display style of the target object.
Each graphic element corresponding to the display style comprises: any one or combination of icons, signs, guide lines, historical points. The specific meanings of the icons, the signs and the guiding lines are referred to the detailed description above, and are not repeated herein.
In the embodiment of the invention, the attribute information of the target object can indicate the identity of the target object. For example, when the attribute information of the target object includes the object class attribute, the object class to which the target object belongs may be determined according to the object class attribute, and in practical applications, target objects of different classes may correspond to different display styles, so that the display style of the target object may be determined according to the object class of the target object. For another example, when the attribute information of the target object further includes the key attribute, the importance degree of the target object may be determined according to the key attribute, and in practical applications, the display styles corresponding to target objects of different importance degrees may have differences, so that the display style of the target object is determined according to the object category attribute and the key attribute of the target object.
First, matching may be performed according to attribute information of a target object and indexes corresponding to respective display styles in a display style set created in advance, and a display style successfully matched is determined as the display style of the target object.
The pre-created display style set can be created according to the type, the number and the attribute information of the target object of the target area when the display system is initialized; specifically, when the display style set is created, the primitives in the primitive set are combined, so that different display styles are defined. The primitive set may include the same number of initial primitives as the number of target objects, the initial primitives may include any one or a combination of icons, signs, points, lines, and the like, and each initial primitive may correspond to an initial default value; then, setting one or more indexes for each target object in the target area, wherein the indexes can be the attribute information of the target object; then, the target object may be configured with a display style from the pre-created display style set according to the index of the target object (e.g., the attribute information of the target object) and the indexes of the respective display styles in the pre-created display style set.
In some cases, the pre-created display style set may further include a default display style, and if some target objects with unknown attribute information appear in the display system, the default display style may be configured to the target objects with unknown attribute information.
In the pre-created display style set, target objects with different attributes have certain differences, and each display style corresponds to one or more indexes, for example, the index may be attribute information of the target object. The display styles of the target objects of different attributes are different, while the display styles of the target objects of the same attribute are the same. And if the target object is not matched with the display style according to the pre-created display style set, setting the display style of the target object as a default display style.
For example, the display style of the target object determined in the above manner may include only an icon, or may include an icon and a sign, or may further include an icon, a sign, and a guide line, or may further include an icon and a history point, and the like. For example, in the display system shown in fig. 3, the trajectory display style of the target object includes: icons, signs, and guide lines; the history point display style of the target object includes: icons, signs and history points, wherein the number of the history points can be input by a user or can be predefined. It should be noted that the types and the number of the primitives included in the display styles corresponding to the target objects with different attributes may be set according to actual requirements, which is not limited in the embodiment of the present invention.
And then, configuring the display position of each graphic element corresponding to the display style according to the position information of the target object. Specifically, the method comprises the following steps:
mapping the latitude and longitude information of the target object to a display interface, determining the display position of one or more primitives of the display style of the target object in the display interface, and then determining the display position of other primitives in the display style in the display interface according to the relative position relationship between other primitives in the display style and the one or more primitives with the determined display position.
For example, in the display system shown in fig. 3, the track display style includes an icon, a sign and a guiding line, the latitude and longitude information of the target object is mapped into the display interface, the display position of the icon in the display style of the target object in the display interface is determined, and then the display position of the sign and the guiding line in the display style of the target object in the display interface is determined according to the relative position relationship between the icon and the sign in the display style and the relative position relationship between the icon and the guiding line.
For example, in the display system shown in fig. 3, the history point display style includes an icon, a sign and a history point, then the latitude and longitude information of the target object is mapped into the display interface, the display position of the icon in the display style of the target object in the display interface is determined, and then the display position of the sign and the history point in the display style of the target object in the display interface is determined according to the relative position relationship between the icon and the sign in the display style and the relative position relationship between the icon and the history point.
In this step, by creating a display style of a target object with a rated capacity in advance, when a new target object appears, one display style is allocated to the target object in the set of created display styles in advance, so that the display style of the first appearing target object is prevented from being configured in a dynamic manner.
S403', difference processing is carried out according to the position information and the attribute information corresponding to the target object, so as to update the display style of the target object.
A possible implementation manner is that, according to the position information and the attribute information corresponding to the target object, the display style corresponding to the target object in the memory of the display device is updated, specifically, the updating of the display style corresponding to the target object in the memory of the display device includes updating the attribute values of one or more primitives of the display style of the target object.
Illustratively, according to the position information and the attribute information corresponding to the target object, the display position of each graphic element corresponding to the display style of the target object in the display interface is updated, and the text content in the sign in the display style of the target object is updated.
Updating the display position of each primitive corresponding to the display style of the target object in the display interface comprises the following steps: if the position of the target object is determined to be changed, updating the display position of the icon in the display style of the target object in the memory in the display interface according to the position information of the target object in the network data packet, and updating the display positions of other primitives in the display style of the target object in the memory in the display interface according to the relative position relationship between the icon and other primitives in the display style.
Updating the text to be displayed in the label in the display style of the target object in the memory comprises: the target object may be divided into a plurality of regions, such as a static region and a dynamic region, wherein the attribute items in the static region (i.e., the text content in the static region) may not be updated, and the text content in the dynamic region may be updated according to the network data according to a preset period. And if the attribute values corresponding to one or more attribute items in the dynamic area of the sign of the display style of the target object are determined to be changed, updating the attribute values corresponding to the changed one or more attribute items in the sign of the display style of the target object in the display card. And updating the attribute items of which the attributes and the attribute values are unchanged in the signs of the display style of the target object.
S404, calling a rendering engine, and generating a rendering instruction according to the display style of the target object.
Wherein the step comprises rendering for a first appearing target object and rendering for a displayed target object. Specifically, the method comprises the following steps:
and aiming at a target object which appears for the first time, after the display style of the target object is determined and configured, calling a rendering engine, copying the data of the display style of the target object in the memory of the display device into the display memory of the display card, generating a first rendering instruction, and indicating the display card to render aiming at the target object which appears for the first time according to the first rendering instruction so as to display the state of the target object in a display interface.
And for the displayed target object, after the display style of the displayed target object in the memory of the display device is updated, calling a rendering engine, copying data of the display style of the target object in the memory of the display device into a display memory of a display card, generating a second rendering instruction, and instructing the display card to render for the displayed target object according to the second rendering instruction so as to display the latest state of the displayed target object in a display interface.
In this embodiment, a network data packet including position information and attribute information corresponding to a target object in a target area is obtained, and according to the network data packet, if it is determined that the target object appears for the first time, a display style of the target object is determined and configured, where the display style includes each primitive corresponding to the target object and a display position of each primitive in a display interface, and an attribute value of each primitive corresponding to the target object is determined according to the attribute information of the target object, and a display position of each primitive corresponding to each primitive is determined according to the position information of the target object, then, a rendering engine is invoked, and a first rendering instruction is generated according to the display style of the target object, where the first rendering instruction is used to instruct a display card to render according to the display style of the target object. According to the method provided by the embodiment, aiming at a target object which appears for the first time, a display style of the target object is configured according to a pre-established display style set and according to needs; and performing differential processing on the displayed target object according to the network data packet, and only updating variable data corresponding to the displayed target object, so that the resource consumption of a GPU and a CPU in the display process is reduced, and the processing efficiency of the display device is improved.

And the display style updating instruction is used for indicating the display style corresponding to the updating target object. Namely, the attribute values for indicating to update one or more primitives in the display style corresponding to one or more target objects in the target region. For example, the display style update instruction may be a display style for instructing to update a target object of a certain object category, or may be a display style for instructing to update a target object of a certain emphasis degree.
