Aiming at the problems in the prior art, the embodiment of the invention provides a display method, which improves the processing efficiency of a display device and reduces the resource consumption of a CPU and a GPU. The display method provided by the invention is described in detail below through several specific embodiments.
Fig. 4 is a flowchart of a display method according to a first embodiment of the present invention. The execution body of the display method provided by the embodiment of the invention can be the display device provided by the embodiment of the invention, and the display device can be realized by any software and/or hardware mode, wherein the display device can be integrated in a display system or can be independently arranged.
The display device may be, for example, a smart phone, a portable electronic device, a computer, a server, or the like, or may be part of the above device. In this embodiment, a display device is taken as an example of an execution body.
As shown in fig. 4, the method of the present embodiment includes:
s401, acquiring 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.
Illustratively, the location information corresponding to the target object may be latitude and longitude information, where the location information may be acquired by a location module (or may also be referred to as a location sensor) of the target object, for example, the location module may be a Global Positioning System (GPS) module, or may be another module capable of acquiring the location 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 mode of the target object in the display interface according to the position information corresponding to the target object.
For example, the attribute information corresponding to the target object may be an object category attribute, an emphasis attribute, and the like. The object category attribute is used for indicating a category to which the target object belongs; the key attribute is used for indicating the importance degree of the target object, in practical application, the object class and the importance level of the target object can be preset for all the target objects in the display system, and when the target object sends data to the network device, the information of the object class and/or the importance level (key attribute) of the target object is also sent to the network device. In this scheme, the attribute information of the target object may be used to determine the kind of primitives included in its display style, the number of primitives, and the attribute value of the primitives.
In one possible implementation manner, the target object in the target area sends its own position information, attribute information, other state information and other data to the network device, the network device can process and cache the received data, and the display device can acquire the position information, attribute information and other state information corresponding to one or more target objects in the target area from the network device.
By way of example, other status information of the target object referred to herein may include 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, if it is determined that the target object appears for the first time, S403 is executed, and if it is determined that the target object does not appear for the first time, S403' is executed.
In one possible implementation manner, the attribute information corresponding to the target object includes an identity identifier corresponding to the target object, the display device matches the identity identifier corresponding to the target object with the displayed identity identifier of the target object, if the matching is unsuccessful, the target object is determined to appear for the first time, and a corresponding display style is created for the target object appearing for the first time, that is, S403 is executed; if the matching is successful, determining that the target object and the displayed target object which is successfully matched are the same object, and updating the state of the target object in the display interface according to the data in the network data packet without re-creating a corresponding display style for the target object, namely executing S403'.
The identity corresponding to the target object may be an identity ID of the target object, or a device number, or may also be other identities of the target object, which is not limited in the embodiment of the present invention, and in the embodiment of the present invention, the identity only needs to be capable of uniquely identifying the target object.
S403, determining and configuring the display style of the target object.
Wherein, each graphic primitive corresponding to the display style comprises: any one or combination of icons, signage, leads, history points. The specific meaning of the icon, the label and the guide wire is referred to in the above detailed description, and will not be repeated here.
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 an object category attribute, the object category to which the target object belongs may be determined according to the object category attribute, and in practical application, different types of target objects may correspond to different display styles, so that the display style of the target object may be determined according to the object category of the target object. For example, when the attribute information of the target object further includes a key attribute, the importance degree of the target object may be determined according to the key attribute, and in practical application, the display styles corresponding to the target objects with the same object category but 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.
One possible implementation manner may first match, according to attribute information of a target object, an index corresponding to each display style in a pre-created display style set, and determine a successfully matched display style as a display style of the target object.
The pre-created display style set can be created according to the types, the number and the attribute information of the target objects of the target area when the display system is initialized; specifically, when creating a display style set, each primitive in the primitive set is used to combine, thereby defining different display styles. Wherein 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, labels, points, lines, etc., and each initial primitive may correspond to an initial default value; then, setting one or more indexes for each target object of the target area, wherein the indexes can be attribute information of the target object; thereafter, a display style may be configured for the target object from among the pre-created set of display styles based on an index of the target object (e.g., attribute information of the target object) and an index of each display style in the pre-created set of display styles.
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, the pre-created display styles have a certain difference, and each display style corresponds to one or more indexes, for example, the indexes can be attribute information of the target objects. The display styles of the target objects of different attributes are different, and the display styles of the target objects of the same attribute are the same. And if the display style is not matched with the display style for the target object according to the pre-created display style set, setting the display style of the target object as a default display style.
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 finger line, or may further include an icon, a history point, and the like, as examples. For example, in the display system shown in fig. 3, the track display style of the target object includes: icons, signs, and leads; the history point display style of the target object includes: icons, signs, and history points, wherein the number of history points may be user-entered or 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 the actual requirements, which is not limited in the embodiment of the present invention.
And then, according to the position information of the target object, configuring the display positions of the primitives corresponding to the display style. Specifically:
mapping longitude and latitude information of the target object to a display interface, determining display positions of one or more primitives of a display style of the target object in the display interface, and then determining display positions of other primitives of the display style in the display interface according to relative position relations between the other primitives of the display style and the one or more primitives with determined display positions.
In the display system shown in fig. 3, for example, the track display style includes an icon, a label and a guide line, then the longitude and latitude information of the target object is mapped to 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 positions of the label and the guide line in the display style of the target object in the display interface are determined according to the relative position relationship between the icon and the label in the display style and the relative position relationship between the icon and the guide line.
In the display system shown in fig. 3, for example, the history point display style includes an icon, a label and a history point, then the latitude and longitude information of the target object is mapped to 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 positions of the label and the history point in the display style of the target object in the display interface are determined according to the relative position relationship between the icon and the label in the display style and the relative position relationship between the icon and the history point.
In this step, by creating the display style of the target object with rated capacity in advance, when a new target object appears, one of the display styles set created in advance is allocated to the new target object, so that the display style of the target object appearing for the first time is prevented from being configured in a dynamic manner, and if a large number of target objects appearing for the first time exist, the processing efficiency of the display style configured for the large number of target objects can be effectively improved.
S403', performing differential processing 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.
In one possible implementation manner, updating the display style corresponding to the target object in the memory of the display device according to the location information and the attribute information corresponding to the target object specifically includes updating the attribute values of one or more primitives of the display style of the target object in the memory of the display device.
Illustratively, according to the position information and the attribute information corresponding to the target object, the display position of each primitive corresponding to the display style of the target object in the display interface is updated, and the text content in the label in the display style of the target object is updated.
The 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, according to the position information of the target object in the network data packet, the display position of the icon in the display pattern of the target object in the memory in the display interface is updated, and according to the relative position relation between the icon in the display pattern and other graphic elements, the display position of other graphic elements in the display pattern of the target object in the memory in the display interface is updated.
The updating the text to be displayed in the label in the display style of the target object in the memory comprises the following steps: the signage of the display style of the target object may be divided into a plurality of regions, such as a static region and a dynamic region, wherein an attribute item in the static region (i.e., text content in the static region) may not be updated, and 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 the one or more attribute items in the dynamic region of the label of the display style of the target object are determined to change, updating the attribute values corresponding to the one or more attribute items in the label of the display style of the target object in the display card. Wherein, the attribute items in the label of the display style of the target object, the attribute values of which are unchanged, are not updated.
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 the first appearing target object and rendering for the displayed target object. Specifically:
and for the target object which appears for the first time, after determining and configuring the display style of the target object, 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 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 the display interface.
And updating the display pattern of the displayed target object in the memory of the display device, calling a rendering engine, copying the data of the display pattern of the target object in the memory of the display device into the video memory of the display card, generating a second rendering instruction, and indicating the display card to render the displayed target object according to the second rendering instruction so as to display the latest state of the displayed target object in the display interface.
In this embodiment, a network data packet including location information and attribute information corresponding to a target object in a target area is obtained, if it is determined that the target object appears for the first time, a display style of the target object is determined and configured according to the network data packet, where the display style includes each primitive corresponding to the target object and display positions corresponding to the primitives in a display interface, attribute values of the primitives corresponding to the target object are determined according to the attribute information of the target object, the display positions corresponding to the primitives are determined according to the location information of the target object, and then a rendering engine is invoked to generate a first rendering instruction according to the display style of the target object, where the first rendering instruction is used to instruct a graphics card to render according to the display style of the target object.
