In order to solve the technical problem of how to improve the user experience effect, the embodiments of the present disclosure provide a method for controlling the position movement of a virtual object. As shown in fig. 1a, the method for controlling the position movement of the virtual object mainly includes the following steps S1 to S2. Wherein:
step S1: and determining a target plane and a target position of the virtual object in the real scene.
The executing body of this embodiment may be selected as the device for controlling the position movement of the virtual object provided in this disclosure, or the hardware device for controlling the position movement of the virtual object provided in this disclosure, or the terminal for controlling the position movement of the virtual object provided in this disclosure.
The terminal may be, but is not limited to, a mobile terminal (e.g., iPhone, smartphone, tablet, etc.), or a fixed terminal (e.g., desktop computer).
The virtual object can be selected as a three-dimensional model of a real object in a scene.
The target plane is a plane to which a virtual object is to move in the real scene, and the plane is a surface of an entity located in the real scene, such as, but not limited to, a desktop or a wall surface. The target position is a position to which the virtual object is to move in the real scene, and the target position is on the target plane.
Step S2: and displaying the virtual object on the corresponding terminal screen according to the target position, wherein the displayed virtual object is positioned on the surface of the target plane. The target position can be determined according to a target plane and/or a preset target display position of the virtual object on the terminal screen.
The terminal may be, but is not limited to, a mobile terminal (e.g., iPhone, smartphone, tablet, etc.), or a fixed terminal (e.g., desktop computer).
Specifically, after the target plane and the target position of the virtual object in the real scene are determined, the virtual object is placed at the target position, or the virtual object is controlled to move to the target position, and then the virtual object is displayed at the determined target position, so that the virtual object is displayed on the corresponding terminal screen, as shown in fig. 1b, and the displayed virtual object is located on the surface of the target plane, and therefore the virtual object viewed through the terminal screen is located right on the surface of the target plane, and is not suspended or embedded in the plane.
By adopting the technical scheme, the target plane and the target position of the virtual object in the real scene are determined, the virtual object is displayed on the corresponding terminal screen according to the target position, and the displayed virtual object is located on the surface of the target plane, so that the situation that the virtual object is suspended on the plane or embedded into the plane when moving can be avoided, and the display effect of the terminal is improved.
In an alternative embodiment, as shown in fig. 1c, the step of determining the target plane of the virtual object in the real scene in step S1 includes:
s11: planes contained in a real scene are identified.
Among them, the real scene may include one or more planes. The plane included in the real scene can be identified by using a corresponding algorithm, which can be implemented by using the prior art, for example, a simultaneous localization and mapping (SLAM) algorithm, which is not described herein again.
S12: one of the identified planes is selected as a target plane.
Further, step S12 can be implemented in two ways:
in the first way, one plane is automatically selected as the target plane, i.e., one plane is automatically selected as the target plane from among the identified planes.
In the second mode, a user selects a target plane, namely, the identified plane is displayed on a terminal screen and is in a selectable state; and taking the selected plane as a target plane. That is, the user may select a plane by clicking or double-clicking or other preset actions, and take the plane selected by the user as the target plane.
Exemplarily, as shown in fig. 1d, planes 1-3 in the recognized real scene are sequentially displayed on the terminal screen, and if a plane is automatically selected as the target plane, a plane may be automatically selected by the system according to a preset rule, for example, the first recognized plane is automatically selected; if the user wants to display the virtual object on the plane 1, the user only needs to click or double click on the plane 1 on the terminal screen to complete the selection operation. When the plane 1 is selected, it is displayed on the terminal screen according to its placement position in the display scene, as shown in fig. 1 e.
In an alternative embodiment, as shown in fig. 1f, the step of determining the target position of the virtual object in the real scene in step S1 includes:
s13: and determining the target display position of the virtual object on the terminal screen.
And the target display position is the display position of the virtual object on the terminal screen.
S14: and determining the target position according to the target display position and the target plane.
Further, the step S13 may obtain the target display position in two ways: the first mode is as follows: and detecting a first trigger response generated on a terminal screen, and taking the generation position of the first trigger response as a target display position.
The first trigger response is a response generated by a trigger operation acting on the terminal screen, and may be, but is not limited to, a click response generated for the terminal screen, or a double-click response, or a detected preset gesture action. To distinguish another differently-acting trigger response that appears hereinafter, a trigger response that appears here is referred to as a first trigger response, and a subsequently-appearing trigger response is referred to as a second trigger response in turn.
The generation position of the first trigger response is a point on the corresponding plane of the terminal screen, and can be determined by a sensor arranged on the terminal screen.
Specifically, if the user wants to change the display position of the virtual object on the terminal screen, an operation needs to be performed on the terminal screen, for example, by clicking, or double clicking, or making a preset gesture motion on the terminal screen to determine the next display position of the virtual object. The terminal screen generates a trigger response after receiving the operation, wherein the generation position of the trigger response is the display position where the user wants to move the virtual object, and the display position is not the target position of the virtual object in the real scene, so that the target position of the virtual object in the real scene needs to be determined according to the trigger response, and the display position of the virtual object on the terminal screen can be accurately positioned.
In the second mode, an input target display position is received.
Specifically, the user can input the target display position through the terminal, and because the trigger operation of the user on the terminal screen is often a trigger area and is difficult to locate to a point, the point can be accurately located by inputting the target position, therefore, compared with the trigger operation of the user on the terminal screen, the position of the virtual object can be more accurately located, and the terminal display effect is further improved.
Further, step S14 includes:
acquiring a line passing through a point where the target display position is located;
the intersection of the line and the target plane is taken as the target position.
Wherein the line may be a straight line, a ray or a line segment.
Further, the line is perpendicular to the plane of the terminal screen.
In an optional embodiment, before detecting the first trigger response generated on the terminal screen, the method of the present disclosure further includes:
detecting a second trigger response aiming at the virtual object generated on the terminal screen, wherein the second trigger response is used for enabling the virtual object to be in a selected state;
accordingly, before step S2, the method further includes:
and controlling the virtual object to move to the target position according to the second trigger response and the first trigger response.
The second trigger response is a response generated by the terminal screen acting on the virtual object, and may be, but is not limited to, a click response generated by the terminal screen, or a double click response, or a detected preset gesture action.
Further, the step of controlling the virtual object to move to the target position according to the second trigger response and the first trigger response, and enabling the virtual object to be located on the surface of the target plane includes:
and after detecting the first trigger response, directly moving the virtual object to the target position, or dragging the virtual object to the target position along with the motion track.
Specifically, for the user plane, the present step may include the following two specific implementations: firstly, clicking a virtual object on a terminal screen, and then clicking a target position on the terminal screen, wherein the virtual object directly moves to the target position under the control of the method; the second method clicks a virtual object on the terminal screen, and then drags the virtual object to a target position on the terminal screen.
If the method is the first implementation manner, clicking a virtual object on a terminal screen, then clicking a target position on the terminal screen, after clicking a new position on the terminal screen, acquiring a line (such as a line) passing through the point of the position, wherein the intersection point of the line and a plane to which the virtual object is to move in a real scene is the new target position of the virtual object, and placing the virtual object on the target position; if the second implementation mode is adopted, the new target position is continuously calculated according to a certain time interval, and the virtual object moves along the motion track of the new target position to form a moving track animation.
By adopting the above technical solution, the embodiment can avoid the situation that the virtual object floats on the plane or is embedded in the plane when moving by identifying the planes contained in the real scene, selecting the plane from the planes as the target plane, determining the target position of the virtual object in the real scene, and displaying the virtual object on the corresponding terminal screen according to the target position, wherein the displayed virtual object is located on the surface of the target plane, thereby improving the display effect of the terminal.
In an alternative embodiment, as shown in fig. 1g, the method of the present disclosure further comprises:
s0: determining the initial position of the virtual object in the real scene according to the initial position of the virtual object on the terminal screen;
accordingly, before step S2, the method further includes:
and controlling the virtual object to move from the initial position to the target position.
Wherein, the initial position of the terminal screen can be selected as the central position of the terminal screen. The specifics may be determined by the user. In this embodiment, the method for determining the initial position of the terminal screen and the method for determining the initial position in the real scene are similar to the method for determining the target display position and the target position, and are not described herein again.
In an optional embodiment, before step S2, the method further includes:
when a plurality of virtual objects are detected, if one of the virtual objects is detected to be selected, the other virtual objects are controlled to move to the target position along with the selected virtual object in sequence;
or, when a plurality of virtual objects are detected, if all the virtual objects are simultaneously selected, the plurality of virtual objects are simultaneously controlled to move to the target positions.
Specifically, one or more virtual objects can be moved in the plane, and one virtual object can be moved or a plurality of virtual objects can be moved simultaneously when the virtual objects are moved. When a plurality of virtual objects exist, one virtual object is selected to move, and the movement of the other virtual objects is the same as that of the selected virtual object; or simultaneously selecting a plurality of virtual objects to move, and calculating the intersection point of each line and the plane for each virtual object corresponding to one line and one plane, thereby obtaining the target position of each virtual object.
It will be appreciated by those skilled in the art that obvious modifications (e.g., combinations of the enumerated modes) or equivalents may be made to the above-described embodiments.
In the above, although the steps in the embodiment of the method for controlling the position of the virtual object are described in the above sequence, it should be clear to those skilled in the art that the steps in the embodiment of the present disclosure are not necessarily performed in the above sequence, and may also be performed in other sequences such as reverse, parallel, and cross, and further, on the basis of the above steps, those skilled in the art may also add other steps, and these obvious modifications or equivalents should also be included in the protection scope of the present disclosure, and are not described in detail herein.
For convenience of description, only the relevant parts of the embodiments of the present disclosure are shown, and details of the specific techniques are not disclosed, please refer to the embodiments of the method of the present disclosure.

The target position is a position to which the virtual object is to move in the real scene, and the target position is on the target plane.
The target position can be determined according to the target plane and/or a preset target display position on the terminal screen.

When the plane 1 is selected, it is displayed on the terminal screen according to its placement position in the display scene, as shown in fig. 1 e.
In an alternative embodiment, as shown in fig. 2c, the plane and position determining module 21 comprises: a display position determination unit 213 and a position determination unit 214; the display position determining unit 213 is configured to determine a target display position of the virtual object on the terminal screen; the position determining unit 214 is configured to determine a target position according to the target display position and the target plane.
And the target display position is the display position of the virtual object on the terminal screen.
The display position determining unit 213 is specifically configured to detect a first trigger response generated on the terminal screen, and use a generation position of the first trigger response as a target display position, or receive an input of the target display position.
The first trigger response is a response generated by a trigger operation acting on the terminal screen, and may be, but is not limited to, a click response generated for the terminal screen, or a double-click response, or a detected preset gesture action. To distinguish another differently-acting trigger response that appears hereinafter, a trigger response that appears here is referred to as a first trigger response, and a subsequently-appearing trigger response is referred to as a second trigger response in turn.
The generation position of the first trigger response is a point on the corresponding plane of the terminal screen, and can be determined by a sensor arranged on the terminal screen.
Specifically, if the user wants to change the display position of the virtual object on the terminal screen, an operation needs to be performed on the terminal screen, for example, by clicking, or double clicking, or making a preset gesture motion on the terminal screen to determine the next display position of the virtual object. The terminal screen generates a trigger response after receiving the operation, wherein the generation position of the trigger response is the display position where the user wants to move the virtual object, and the display position is not the target position of the virtual object in the real scene, so that the target position of the virtual object in the real scene needs to be determined according to the trigger response, and the display position of the virtual object on the terminal screen can be accurately positioned.
Or the user can input the target display position through the terminal, because the trigger operation of the user on the terminal screen is often a trigger area and is difficult to locate to a point, and the point can be accurately located by inputting the target position, the embodiment can better accurately locate the position of the virtual object relative to the trigger operation of the user on the terminal screen, and further improve the terminal display effect.
Further, the position determining unit 213 is specifically configured to: acquiring a line passing through a point where the target display position is located; the intersection of the line and the target plane is taken as the target position.
Wherein the line may be a straight line, a ray or a line segment.
Further, the line is perpendicular to the plane of the terminal screen.
In an alternative embodiment, the display position determination unit 213 is further configured to: before detecting the first trigger response generated on the terminal screen, detecting a second trigger response generated on the terminal screen and aiming at the virtual object, wherein the second trigger response is used for enabling the virtual object to be in a selected state;
correspondingly, the display module 22 is further configured to: and controlling the virtual object to move to the target position according to the second trigger response and the first trigger response before the virtual object is displayed on the corresponding terminal screen according to the target position and the displayed virtual object is positioned on the surface of the target plane.
The second trigger response is a response generated by the terminal screen acting on the virtual object, and may be, but is not limited to, a click response generated by the terminal screen, or a double click response, or a detected preset gesture action.
Further, the display module 22 is specifically configured to: and after detecting the first trigger response, directly moving the virtual object to the target position, or dragging the virtual object to the target position along with the motion track.
Specifically, for standing on the user plane, the display module 22 is specifically used in the following two scenarios: firstly, clicking a virtual object on a terminal screen, and then clicking a target position on the terminal screen, wherein the virtual object directly moves to the target position under the control of the method; the second method clicks a virtual object on the terminal screen, and then drags the virtual object to a target position on the terminal screen.
If the first type is adopted, clicking a virtual object on a terminal screen, then clicking a target position on the terminal screen, after clicking a new position on the terminal screen, acquiring a line (such as a line) passing through the point of the position, wherein the intersection point of the line and a plane to which the virtual object is to move in a real scene is the new target position of the virtual object, and placing the virtual object on the target position; if the target position is the second type, continuously calculating a new target position according to a certain time interval, and moving the virtual object along the motion track of the new target position to form a moving track animation.
Further, the display module 22 is further configured to: when a plurality of virtual objects are displayed on a corresponding terminal screen according to a target position and the displayed virtual objects are positioned in front of the surface of the target plane, if one virtual object is detected to be selected, the other virtual objects are controlled to move to the target position along with the selected virtual object in sequence; or, when a plurality of virtual objects are detected, if all the virtual objects are simultaneously selected, the plurality of virtual objects are simultaneously controlled to move to the target positions.
In an alternative embodiment, as shown in fig. 2a, the plane and position determining module 21 is further configured to: determining the initial position of the virtual object in the real scene according to the initial position of the virtual object on the terminal screen; correspondingly, the display module 22 is further configured to: and controlling the virtual object to move from the initial position to the target position before the virtual object is displayed on the corresponding terminal screen according to the target position and the displayed virtual object is positioned on the surface of the target plane.
