Fig. 1 shows a schematic flow diagram of a special effect addition method according to an embodiment of the present application.

As shown in fig. 1, the method comprises the steps of:

step S101, monitoring a target special effect adding triggering operation of a user on a target key point of an entity object to be processed displayed on a terminal screen.

Specifically, the entity object to be processed refers to an entity object to be added with a special effect, and may be, for example, a human-shaped handheld, a pet demon handheld, a static character, a dynamic character, and the like, the key point is a key part of the entity object to be processed, and taking the human-shaped handheld as an example, the key point may be a human body part such as a five-sense organ, a hand, a foot, a shoulder, and the like of the human-shaped handheld, and mainly relates to 33 human body key parts, which are not listed here.

In general, an entity object to be processed is displayed through a terminal device, a user can visually check the entity object to be processed through a terminal screen, a target key point is a key point to which the user wants to add a special effect, and a target special effect is a specific special effect which the user wants to add to the target key point of the entity object to be processed, for example, a photosphere special effect, a flame special effect, and the like. In order to add a special effect in time, a trigger operation of adding the special effect to a target key point of a to-be-processed entity object displayed on a terminal screen by a user needs to be monitored.

And step S102, responding to the target special effect adding triggering operation, and determining the screen position information corresponding to the target key point.

In order to enable the target special effect to be accurately displayed at the user target key point, in response to the target special effect addition trigger operation, screen position information corresponding to the target key point needs to be determined. The screen position information reflects the actual position of the target key point on the terminal screen, and the screen position information corresponding to the target key point is determined, so that the special effect can be accurately added according to the screen position information, and the problem that the target special effect adding position is inaccurate is solved.

And step S103, adding the target special effect to a target key point of the entity object to be processed according to the screen position information, and dynamically displaying the target special effect according to the corresponding depth of field change parameter of the entity object to be processed in the terminal screen.

The target special effect is a special effect that a user wants to add to a target key point, and after the screen position information of the target key point is determined, the target special effect can be added to the target key point of the entity object to be processed according to the screen position information, for example, the target key point is a right hand of a humanoid hand, the target special effect is a photosphere special effect, here, the photosphere special effect is added to the right hand of the humanoid hand, and from the viewpoint of visual effect, the photosphere is emitted by the right hand of the humanoid hand.

The corresponding depth of field change parameter of the entity object to be processed in the terminal screen visually reflects the distance of the entity object to be processed seen by a user through the terminal screen relative to the terminal screen, and the target special effect added to the target key point can dynamically display the target special effect according to the corresponding depth of field change parameter of the entity object to be processed in the terminal screen, namely, the target special effect added to the target key point dynamically changes along with the change of the depth of field change parameter.

According to the scheme, the intelligent special effect increasing method and the intelligent special effect increasing device, the intelligent special effect increasing is achieved, in addition, the target special effect is dynamically displayed according to the depth of field change parameters, the special effect is not statically and invariably presented any more, the user can visually see the change of the target special effect, the interestingness of the user is improved, therefore, more users can be attracted to add the special effect to the entity object to be processed, and drainage is achieved.

Fig. 2A shows a schematic flow diagram of a special effect addition method according to another embodiment of the present application. As shown in fig. 2A, the method includes the steps of:

step S201, performing key point identification processing on the entity object to be processed to obtain the screen position information of each key point on the terminal screen.

In order to perform special effect addition with pertinence, it is necessary to perform key point identification processing on an entity object to be processed displayed on a terminal screen, for example, the entity object to be processed may be performed with a MediaPipe frame, and screen position information of each key point on the terminal screen may be obtained through the identification processing, where the screen position information of each key point on the terminal screen reflects an actual position of the key point on the terminal screen.

In a specific implementation, the screen position information of each key point on the terminal screen can be further determined by the following method: and carrying out key point identification processing on the entity object to be processed to obtain the relative position information of each key point relative to the terminal screen, and calculating the screen position information of each key point on the terminal screen according to the relative position information and the terminal screen size.

The relative position information of the key point relative to the terminal screen is the position of the key point relative to the terminal screen, wherein the relative position information comprises screen width relative position information and screen height relative position information, specifically, the relative position information is expressed by a numerical value between two values of 0-1, wherein 0 represents that the key point is in the leftmost side of the terminal screen, 1 represents that the key point is in the rearmost side of the terminal screen, 0 represents that the key point is in the lowermost side of the terminal screen, 1 represents that the key point is in the uppermost side of the terminal screen, and by taking the key point as a nose as an example, the relative position information of the nose relative to the terminal screen is { x:0.5, y 0.5}, wherein x represents that the horizontal coordinate of the nose in the terminal screen is 0.5 times of the screen width, and y represents that the vertical coordinate of the nose in the terminal screen is 0.5 times of the screen height; for another example, the relative position information is { x:0.4, y; this is by way of illustration only and not by way of limitation; the relative position information of the key point relative to the terminal screen is determined based on the current position of the entity object to be processed on the terminal screen, and when the position of the entity object to be processed in the terminal screen changes, the determined relative position information changes accordingly.

The terminal screen sizes of terminal devices of different brands and different models may be slightly different, in order to accurately add a target special effect, after determining the relative position information, the screen position information of each key point on the terminal screen is calculated according to the relative position information and the terminal screen size, and the calculated screen position information is the actual position of each key point of the entity object to be processed on the terminal screen, wherein the screen position information includes: the screen width position information and the screen height position information, for example, the screen width relative position information may be multiplied by the terminal screen width value to obtain the screen width position information of each key point on the terminal screen; and multiplying the relative position information of the screen height by the height value of the terminal screen to obtain the screen height position information of each key point on the terminal screen.

For example, when calculating the screen position information of the nose on the terminal screen, the screen width position information of the nose on the terminal screen is obtained by multiplying 0.4 by the terminal screen width value, and the screen height position information of the nose on the terminal screen is obtained by multiplying 0.5 by the terminal screen height value, for example, the terminal screen width value is 8.09 cm, and the terminal screen height value is 14.39 cm, and the calculated result is the screen position information of the nose on the terminal screen.

The execution main body of the special effect adding method provided by the embodiment is a client, the client can be a page with a special effect adding function, the page can be opened through a browser to perform special effect addition, and when the special effect is added, the screen position information of each key point on a terminal screen is calculated through a frame layer and a page layer: the frame layer carries out key point identification processing on the entity object to be processed to obtain the relative position information of each key point relative to the terminal screen, and transmits the relative position information corresponding to each key point to the page layer; and the page layer calculates the screen position information of each key point on the terminal screen according to the relative position information and the terminal screen size.

Step S202, monitoring the target special effect adding triggering operation of the target key point of the entity object to be processed displayed on the terminal screen by the user.

Specifically, the method can be realized by the following steps: the terminal screen can display a special effect panel, all the special effects which can be added and key point identifications of all key points of the entity object to be processed can be displayed in the special effect panel, a user can select the special effect which is desired to be added and the key points of the special effect which is desired to be added in the special effect panel, and after the selection operation of the special effect displayed on the terminal screen and the key points of the entity object to be processed by the user is monitored, the target key points and the target special effects can be determined according to the selection operation.

Or judging whether any key point in the entity object to be processed displayed on the terminal screen has a preset action or not; if yes, determining the key point with the preset action as a target key point, and determining the special effect associated with the preset action as a target special effect corresponding to the target key point. Specifically, the association relationship between the preset action and the special effect is preset, and the preset action and the corresponding special effect can be flexibly set according to needs, for example, if a fist is associated with the flame special effect, a palm extending is associated with the photosphere special effect, and a certain key point in the entity object to be processed makes a fist making action, the key point can be determined as a target key point, and the flame special effect associated with the fist making action is determined as the target special effect.

Step S203, responding to the target special effect adding triggering operation, and determining the screen position information corresponding to the target key point.

In order to enable the target special effect to be accurately displayed at the user target key point, in response to the target special effect addition trigger operation, screen position information corresponding to the target key point needs to be determined. Since the screen position information of each key point of the entity object to be processed has already been determined in step S201, after the target key point for special effect addition is determined, the screen position information corresponding to the target key point can be directly determined. The screen position information reflects the actual position of the target key point on the terminal screen, and the screen position information corresponding to the target key point is determined, so that the special effect can be accurately added according to the screen position information, and the problem that the target special effect adding position is inaccurate is solved.

Step S204, dynamically calculating the coordinate distance between the two reference key points according to the screen position information corresponding to the two preset reference key points, and dynamically determining the special effect size corresponding to the target special effect according to the coordinate distance.

The selection principle of the reference key points is mainly considered from the stability point of view, and the two reference key points do not generate bending displacement and the like. Taking a human-shaped handheld as an example, the two selected reference key points are the right shoulder and the left hip.

The screen position information of the two reference key points is determined in the above step, and when the entity object to be processed has displacement change in depth relative to the terminal screen, the coordinate distance between the two reference key points is dynamically calculated according to the screen position information corresponding to the two preset reference key points, for example, the two preset reference key points: the coordinates of the right shoulder (point a) and the left hip (point B) are { x1, y1}, { x2, y2}, respectively, so that the distance between the two points can be calculated from the coordinates of the two reference key points using the following formula:

the distance between the two reference key points also reflects the distance between the entity object to be processed and the terminal screen, and the farther the entity object to be processed is from the terminal screen, the smaller the distance between the two points is; the closer the entity object to be processed is to the terminal screen, the greater the distance between the two points, therefore, the corresponding depth of field change parameter of the entity object to be processed in the terminal screen can also be determined by the coordinate distance between the two reference key points. The coordinate distance between the two reference key points is reduced from large, the corresponding depth of field change parameters are changed from near to far, the coordinate distance between the two reference key points is increased from small to large, and the corresponding depth of field change parameters are changed from far to near.

In order to enable the special effect size of the added target special effect to be adapted to the size of the entity object to be processed currently displayed on the terminal screen, the special effect size corresponding to the target special effect is dynamically determined according to a coordinate distance, for example, the special effect size of the target special effect is equal to a product of the coordinate distance between two reference key points and a preset value, where the preset value may be flexibly set according to actual experience, for example, the preset value is 5.

And step S205, adding the target special effect to the target key point of the entity object to be processed according to the screen position information.

The target special effect is a special effect which a user wants to add to a target key point, after the screen position information of the target key point is determined, the actual position of the target key point in a terminal screen can be determined according to the screen position information, then the target special effect is added to the corresponding position, and from the visual effect, the target special effect is added to the target key point of the entity object to be processed, for example, the target key point is the right hand of a man-shaped hand, and the target special effect is a photosphere special effect which is added to the right hand of the man-shaped hand. The target effect may include a sequence frame effect and a particle effect.

And step S206, dynamically displaying the target special effect according to the determined special effect size according to the corresponding depth of field change parameter of the entity object to be processed in the terminal screen.

From the visual effect, the target special effect changes with the distance between the entity object to be processed and the terminal screen. The distance between the entity object to be processed and the terminal screen can be defined by a depth of field change parameter, and if the depth of field change parameter corresponding to the entity object to be processed in the terminal screen is from near to far, the target special effect is dynamically displayed in a mode that the size of the special effect is from large to small; and if the depth of field change parameters corresponding to the entity object to be processed in the terminal screen are from far to near, dynamically displaying the target special effect according to the mode that the size of the special effect is from small to large. That is, from the visual effect, the closer the entity object to be processed is to the terminal screen, the larger the special effect size of the target special effect is, and the farther the entity object to be processed is from the terminal screen, the smaller the special effect size of the target special effect is, it should be noted that the closer the entity object to be processed is to the terminal screen also reflects the size of the entity object to be processed displayed in the terminal screen, the closer the entity object to be processed is to the terminal screen, the larger the size of the entity object to be processed is seen, and here, the size of the special effect of the whole target special effect changes, and the size of the target special effect and the size of the entity object to be processed change simultaneously, and is not static as the target special effect in the prior art does not change.

In the embodiment, the screen position information of the target key point can be determined at regular time, so that the displayed position of the target special effect is updated correspondingly. The coordinate distance between the two reference key points also needs to be calculated at regular time, so that the special effect size of the target special effect is updated correspondingly.

In an alternative embodiment of the present application, the method further comprises: and responding to the special effect video recording request, and recording the entity object video to be processed added with the target special effect.

Specifically, a video recording button may be displayed on the terminal screen, and after the user clicks the video recording button, the user regards that a special-effect video recording request is sent, and records the to-be-processed entity object video added with the target special effect in response to the special-effect video recording request. After the recording is finished, the recorded to-be-processed entity object video can be automatically stored in the terminal equipment.

In an alternative embodiment of the present application, the method further comprises: and responding to a video one-key issuing request triggered by a user, and issuing the recorded entity object video to be processed added with the target special effect in a target page.

Specifically, the video recording function may be built in the client, and the client may integrate a one-key publishing capability, for example, a publishing button is provided, and a user may directly publish the to-be-processed entity object video added with the target special effect in the target page by clicking the publishing button, thereby reducing user operation steps. For example, the recorded video of the entity object to be processed with the target special effect added thereto may be directly published in the review area of the commodity.

In an optional embodiment of the present application, the target special effect may not only have a change in size, but also may have a change in form, and it may be determined whether a preset behavior exists in the entity object to be processed within a preset time according to screen position information corresponding to the target key point, if so, the special effect form of the target special effect at the target key point is updated, specifically, a moving distance of the target key point within the preset time is calculated according to the screen position information corresponding to the target key point, and it is determined whether a preset behavior exists based on the moving distance, for example, a pushing behavior, and the like.

In addition, whether the action corresponding to the target key point is changed from the first action to the second action can be judged, and if yes, the special effect form of the target special effect at the target key point is updated according to the changed second action. For example, the target key point is the right hand of the humanoid hand, the right hand changes from palm stretching to fist making, the target special effect is the diamond, and the diamond can be changed from a complete form to a broken form when the right hand changes to fist making.

The following description is made with reference to fig. 2B to fig. 2E by taking an example of recording a human-shaped handheld video with special features added as an example:

specifically, when a user wants to record a video added with a special human-shaped handheld, a corresponding client can be opened, for example, the client is a game page, and the game page comprises a framework layer and an H5 game layer.

The terminal screen will display a special effect panel, as shown in fig. 2C, in the special effect panel, the user selects a special effect desired by the user, and the user selects a photosphere special effect in the right hand. The H5 game layer creates a corresponding photosphere effect and sets the photosphere effect to a right hand position, wherein the effect size of the photosphere effect is determined according to the coordinate distance between the right shoulder and the left hip of the reference key point. The user clicks the video recording button, the UI interface can be automatically hidden, and the screen recording is started, as shown in FIG. 2D, namely, the H5 game layer calls the frame video recording interface, the frame layer can start the video recording, and the H5 game layer is notified after the video recording is finished, the H5 game layer obtains the video recording result and calls the album storage interface, and the recorded video is stored in the album, as shown in FIG. 2E.
