It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
Referring to fig. 1, a block diagram of a data processing apparatus 100 according to an embodiment of the present disclosure is shown. The data processing apparatus 100 may be any electronic apparatus having a data processing function, such as a Personal Computer (PC), a server, a tablet Computer, and a smart phone. The data processing apparatus 100 includes an image linkage 110, a machine-readable storage medium 120, a processor 130, a communication unit 140, and a display unit 150.
The elements of the machine-readable storage medium 120, the processor 130, the communication unit 140, and the display unit 150 are electrically connected to each other, directly or indirectly, to enable transmission or interaction of data. For example, the components may be electrically connected to each other via one or more communication buses or signal lines. The machine-readable storage medium 120 stores machine-executable instructions, and the processor 130 may perform the image linkage method described below by reading and executing the machine-executable instructions of the machine-readable storage medium 120 corresponding to the image linkage logic.
The machine-readable storage medium 120 referred to herein may be any electronic, magnetic, optical, or other physical storage device that can contain or store information such as executable instructions, data, and the like. For example, the machine-readable storage medium 120 may be: a RAM (random Access Memory), a volatile Memory, a non-volatile Memory, a flash Memory, a storage drive (e.g., a hard drive), a solid state drive, any type of storage disk (e.g., a compact disk, a DVD, etc.), or similar storage medium, or a combination thereof.
The machine-readable storage medium 120 has stored therein a three-dimensional image and a two-dimensional thumbnail generated based on any two dimensions of the three-dimensional map. Wherein the two-dimensional thumbnail can be generated by the following process: and generating a two-dimensional image based on any two dimensions of the three-dimensional map, and reducing the two-dimensional image to a specified size to obtain the two-dimensional thumbnail.
In practical applications, the coordinates of the three-dimensional image are usually determined by three dimensions, such as the X-axis, Y-axis and Z-axis shown in fig. 2(a), and then a two-dimensional image can be constructed by any two of the X-axis, Y-axis and Z-axis, such as the two-dimensional image constructed based on the X-axis and Y-axis shown in fig. 2(a) shown in fig. 2 (b). And then the two-dimensional image is reduced to a specific size, and a two-dimensional thumbnail can be obtained.
In this embodiment, the two-dimensional thumbnail may be disposed at any position on a display interface where the three-dimensional image is located, for example, may be disposed at an upper right corner, a small left corner, and the like of the three-dimensional image, which is not limited in this embodiment.
Alternatively, the three-dimensional image and the two-dimensional thumbnail may be run on a specific Application (APP) of the data processing apparatus 100, for example, on a browser client. Alternatively, the three-dimensional image may be a three-dimensional map, and correspondingly, the two-dimensional thumbnail may be a thumbnail of a two-dimensional map.
The communication unit 140 is used for establishing a communication connection between the data processing apparatus 100 and other apparatuses to realize data interaction. The display unit 150 is used for displaying information to be displayed (such as the three-dimensional image and the two-dimensional thumbnail, etc., described above) or for enabling interaction with a user.
It should be understood that the configuration shown in fig. 1 is merely illustrative, and that data processing apparatus 100 may also include more or fewer components than shown in fig. 1, or have a completely different configuration than shown in fig. 1. The components shown in fig. 1 may be implemented by software, hardware, or a combination thereof, which is not limited in this embodiment.
Referring to fig. 3, fig. 3 is a flowchart of an image linkage method applied to the data processing apparatus 100 shown in fig. 1, and the method including various steps will be described in detail below.
Step S31, when a position update event of one of the three-dimensional image and the two-dimensional thumbnail is monitored, determining a current position where a camera of the three-dimensional image is located and current coordinate information of a center of a picture captured when the camera is located at the current position.
The camera refers to a camera object arranged in a three-dimensional image, and an observed picture of the camera object is a picture presented to a current user. When the position of the camera in the three-dimensional scene changes, the picture observed by the camera changes, and correspondingly, the picture centers of the three-dimensional image and the two-dimensional thumbnail change correspondingly.
In this embodiment, the user may perform an operation on any one of the three-dimensional image and the two-dimensional thumbnail, for example, a click operation, a drag operation, and the like, and the location update event may be an event triggered by these operations. In this embodiment, a position update event generated by the three-dimensional image and the two-dimensional thumbnail may be monitored through a JavaScript script, and when the position update event is monitored, the current position of the camera in the three-dimensional scene may be determined according to the position update event, so as to determine the position of the center of the picture, which is presented to the user when the camera is located at the current position, that is, the current coordinate information.
And step S32, updating the value of the global variable to the current coordinate information, so that the other one of the three-dimensional image and the two-dimensional thumbnail updates the displayed picture according to the current value of the global variable, and the linkage of the three-dimensional image and the two-dimensional thumbnail is realized.
In this embodiment, the data processing apparatus 100 stores a global variable, for example, the three-dimensional image and the two-dimensional thumbnail are run on a browser client, and the global variable may be a window object used to store coordinate information of the center of the three-dimensional image and the two-dimensional thumbnail. Target, the coordinate information (e.g., X-axis coordinates and Y-axis coordinates) of the three-dimensional image and the screen center of the two-dimensional thumbnail may be acquired as follows: target.x; window. As such, the coordinates of the screen centers of the three-dimensional image and the two-dimensional thumbnail will change as the value of the global variable changes.
Through the global variable, on one hand, the synchronization of the three-dimensional image and the picture center of the two-dimensional thumbnail can be realized. On the other hand, the number of recorded coordinate variables can be reduced, and time consumption caused by data transmission of actual parameters and form parameters can be reduced.
In implementation, after the current coordinate information is determined, the value of the global variable may be updated to the current coordinate information. If a location update event is generated by the three-dimensional image, the two-dimensional thumbnail will be positionally adjusted in accordance with the current value of the global variable such that the picture center is located at the position indicated by the current value of the global variable. If a location update event is generated by the two-dimensional thumbnail, the three-dimensional image will be positionally adjusted in accordance with the current value of the global variable such that the center of the picture is at the location indicated by the current value of the global variable.
In this embodiment, the location update event may be an event generated according to an event triggered by a partial operation of a user. The reason is that: some operations by the user may not cause the change of the center of the screen, and based on this, events triggered by the operations by the user can be distinguished, and the location update event is generated only for the event triggered by a specific operation.
In a specific implementation manner, the image linkage method may include the steps of:
generating the location update event according to the displacement event when the displacement event of the camera is detected.
Wherein the displacement event refers to an event triggered when the coordinates of the camera in the three-dimensional scene change. In this embodiment, since the two-dimensional thumbnail has no direction difference, it is not necessary to link the three-dimensional image and the two-dimensional thumbnail when the viewing direction of the camera is changed.
In another specific implementation manner, the image linkage method may include the steps of:
and when a target click event of the two-dimensional thumbnail is detected, generating the position updating event according to the target click event.
In this embodiment, when the user performs a dragging operation on the two-dimensional thumbnail, a plurality of consecutive operations may be performed, and in order to avoid frequently modifying the global variable, the image linkage method may further include the steps of:
and when detecting that any one of the dragging speed and the dragging direction of two adjacent dragging events of the two-dimensional thumbnail is different, generating a corresponding position updating event according to the last dragging event of the two adjacent dragging events.
For two adjacent drag events with the same drag speed and drag direction, the two drag events can be merged into one drag event.
In the implementation process, for at least two combined dragging events, in the process, since the linkage operation is not performed through the global variable, the pictures presented by the three-dimensional image and the two-dimensional thumbnail may be different, and a click phenomenon may occur.
In response to this problem, the image linkage method provided in this embodiment may further include the steps shown in fig. 4.
Step S41, when it is detected that the dragging speeds and the dragging directions of two adjacent dragging events of the two-dimensional thumbnail are the same, determining a first spacing distance of actual positions of the two adjacent dragging events in a first dimension of the two-dimensional thumbnail and a second spacing distance of the actual positions of the two adjacent dragging events in a second dimension of the two-dimensional thumbnail, and determining a first duration between occurrence times of the two adjacent dragging events.
Wherein, the position of the drag event may refer to a position where the drag event ends the drag.
Step S41 is further explained below by way of an example, assuming: the coordinate of the actual position of the nth drag event in the two-dimensional scene is P1(x1, y1), and the occurrence time thereof is t 1; the coordinate of the actual position of the N-1 th drag event in the two-dimensional scene is P2(x2, y2), and the occurrence time is t 0. In implementation, the moving direction vector of the nth drag event relative to the N-1 st drag event may be calculated as: d1(Δ x, Δ y) ═ x1-x0, y1-y 0.
Where Δ x — x1-x0 is a first separation distance of actual positions of the nth and N-1 th drag events in one dimension (i.e., a first dimension) of the two-dimensional scene. Y1-y0 is a second separation distance of the actual positions of the nth and N-1 th drag events in another dimension (i.e., a second dimension) of the two-dimensional scene.
In addition, the difference between the occurrence time of the nth drag event and the occurrence time of the N-1 th drag event can be calculated, that is, the first time length is: and t is t1-t 0.
Step S42, when a new drag event is detected, if the drag speed and drag direction of the new drag event are not changed with respect to the drag speed and drag direction of the subsequent drag event, predicting to obtain a first drag speed of the new drag event in the first dimension according to the first interval distance and the first time length, and predicting to obtain a second drag speed of the new drag event in the second dimension according to the second interval distance and the first time length.
Step S43, determining a predicted position of the new drag event according to the first drag speed, the second drag, and a second duration between the occurrence time of the new drag event and the next drag event.
Still referring to the above example, assuming that the N +1 th drag event is detected, if the actual position of the N +1 th drag event is P2(x2, y2), the occurrence time is t 2. Then, the predicted position P2' (x2', y2') of the N +1 th drag event may be calculated according to the movement direction vector and the first duration calculated above. In detail, the calculation can be performed by the following calculation formula:
where Δ x/Δ t represents an actual first drag speed in the first dimension from the nth drag event, and in implementation, the actual first drag speed may be used as the first drag speed predicted in the first dimension by the N +1 th drag event. Correspondingly, Δ y/Δ t may be taken as the predicted second drag speed of the N +1 th drag event in the second dimension.
The dragging duration corresponding to the (N + 1) th dragging event is as follows: t2-t1, i.e., the second duration. In this case, the product of the predicted first dragging speed and the second duration is the dragging distance of the (N + 1) th dragging event in the first dimension, the product of the predicted second dragging speed and the second duration is the dragging distance of the (N + 1) th dragging event in the second dimension, and the predicted position of the (N + 1) th dragging event can be determined according to the dragging distances of the (N + 1) th dragging event in the first dimension and the second dimension.
And step S44, when the distance between the predicted position and the actual position of the new drag event reaches a preset value, updating the picture of the three-dimensional image to the picture shot when the camera is at the predicted position.
In practice, it may be determined whether the distance between the predicted positions P2' and P2 reaches the preset value, and if not, it indicates that the N +1 th drag event has been predicted, and it may not be necessary to update the picture of the three-dimensional image. If so, the picture of the three-dimensional image can be updated to present the picture shot when the camera is positioned at the predicted position. Specifically, the determination may be made by the following inequality:
wherein t represents the preset value, and the specific size of the preset value may be determined according to a statistical and testing manner, which is not limited in this embodiment.
Through the design, for multiple combined dragging events, the three-dimensional images and the two-dimensional thumbnails can be basically displayed in the same way under the condition that linkage is not carried out through global variables, and therefore the problem that a user feels stuck is avoided.
