Description

A method of playing system image

technical field

The invention relates to the field of in-vehicle entertainment information systems, in particular to a method for playing system images.

Background technique

At present, several common methods of animation playback include ordinary frame animation playback, H5 (HyperText Markup Language 5, HyperText Markup Language 5) player playback of skeletal animation and game engine attached playback of skeletal animation.

Ordinary frame animation actually cuts each frame of each animation. The size of the animation resource is positively related to the total number of frames of the animation and the number of animations. Because playing frame animation is actually playing a large bitmap picture, compared with skeletal animation, frame animation has a problem of large resource consumption, and frame animation CPU consumption is higher. And because the resources of frame animation are all in the resource library, after the application package is packaged, it cannot be updated remotely.

The H5 skeletal animation player runs on the car entertainment system of the Android platform and needs to be attached to WebView. WebView is a very important control in the android system to display web pages. Because some in-car entertainment systems do not support WebView very well, such models may not be able to play. And because the WebView needs to be loaded before playing, and then the animation is played, the first loading time is long and the scalability is low.

Although the game engine can also play skeletal animation, skeletal animation is not its main business, it is just a way for game sprites to play animation. Take the Cocos 2DX game engine as an example, which also contains Layer (layer), Scene (scene) and Director (director). This also causes the game engine not only to take a long time to start, but also to occupy a large amount of CPU and memory.

Detailed ways

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be more thoroughly understood, and will fully convey the scope of the present disclosure to those skilled in the art.

FIG. 1 is a flowchart of a method for playing a system avatar according to one or more embodiments of the present invention. Referring to FIG. 1, the method includes at least steps S102 to S106.

Step S102, parsing the system image animation resources produced by the skeletal animation to obtain parsing animation data, processing the parsing animation data, and generating an animation library including complete information of each animation in the plurality of animations.

Step S104: Determine the target animation to be played according to the current scene, and obtain complete information of the target animation from the animation library.

Step S106, based on the complete information of the target animation, sequentially render each frame of the target animation, and play each rendered frame frame by frame.

In the above step S102, the system image animation resources may generally include texture set pictures, texture set texts and animation set texts. Among them, the texture set image is a collection of components in all animation frames, which are aggregated and synthesized on a png image. The texture set text is used to describe the position, size and name of the component in the texture set image, which is convenient for clipping the component from the texture set image. The animation set text is a text file used to describe the initial information of each animation and the sub-information of each animation, and the text file may be in json format.

Referring to FIG. 2, in one or more embodiments of the present invention, when parsing a system image animation resource produced by skeletal animation to obtain parsing animation data, the texture set text can be parsed first, and the texture set image can be extracted from the texture set text. The name, position, height and width, as well as the name, height and width of each of the multiple components in the texture set picture, and the relative position of each component in the texture set picture are used as the first part of parsing the animation data. Then, according to the name, height and width of each component in the texture set picture, and the relative position of each component in the texture set picture, each component is cut out from the texture set picture, and each component and the name, height and height of each component are cut out. Wide co-save as the second part of parsing the animation data. Finally, the animation set text is parsed, and the initial information of each animation and the sub-information of each animation are obtained from the animation set text as the third part of parsing animation data. It should be noted that parsing the animation set text and parsing the texture set text do not affect each other, and the two can be performed simultaneously to improve parsing efficiency.

According to one embodiment, texture set text and animation set text can be parsed using the Gson library. For example, when using Gson to parse the text of the texture set, it can be obtained that the name of the phone in the texture set picture is Phone, the height and width are 97×91, and the position in the texture set picture is (1, 497). Certainly, other manners may also be used for parsing, which is not specifically limited in this embodiment of the present invention.

The complete information of each animation includes initial information of the animation, sub-information of the animation, and complete information of each frame of the animation. In the above step S102, when processing the analysis animation data and generating the animation library including the system image animation, the initial information of each animation and the sub-information of each animation can be extracted from the analysis animation data first, according to the initial information of each animation and each animation. The sub-information of the animation calculates the complete information of each frame of each animation. Then, the initial information and sub-information of each animation and the complete information of each frame of the animation are combined together to form the complete information of each animation. Finally, the complete information of all animations is combined to form the system image animation library.

In an embodiment of the present invention, the initial information of each animation may include animation set information, bone information, slot information and component information. The sub-information of each animation may include the basic information of the animation, the movement track of the bone and the display track of the slot. When extracting the initial information of each animation and the sub-information of each animation from the analysis animation data, the animation set information, bone information, slot information and component information can be extracted from the analysis animation data first. Then, the basic information of each animation, the movement track of the bones and the display track of the slot are extracted from the analysis animation data.

In order to explain more clearly how to calculate the complete information of each frame of each animation according to the initial information of each animation and the sub-information of each animation, the following first introduces the relevant names and specific contents involved in parsing the animation set text.

Animation set information, including the name of the animation set, the frame rate of the animation, the size of the canvas, the initial position of the image in the canvas, and the name of the default animation in the animation set.

Bone information, including bone parent-child relationship (including bone name, parent bone name), the initial position of the bone in each animation, the bone scaling size and the bone offset position. Skeletal information is the soul of skeletal animation, and various actions in the system image animation are transmitted through the actions of bones. In the actual animation, the bone moves not only according to itself, but also by the movement of the parent bone. For example, if the parent bone is translated by 30 pixels on the x-axis, the child bone will also be translated by 30 pixels on the x-axis, plus the child's own movement.

Slot information, including slot parent-child relationship (including slot name, parent slot name), component list under the slot, and slot display status. In fact, sockets are attached to bones, but compared to bones, sockets also have a display state. That is to say, by setting the display state of the slot, it is possible to directly control whether the user can see the components on the slot.

Component information, including the name of the component, the location of the component relative to the slot, the size of the component, and the component scaling. Components are attached to slots. Multiple components can be placed in a slot, but only one component can be displayed in a slot at a time. Based on this, the skinning of the system image animation can be realized by replacing the texture set image.

Basic information of each animation, including the animation name, the total number of frames of the animation, and the set number of playbacks.

The motion track of the bone, including the bone translation track, the bone rotation track including the bone rotation angle, and the bone scaling track. Since there is a parent-child relationship between bones, the movement of the parent bone will drive the movement of the child bone. Therefore, the state of the parent bone needs to be taken into account when calculating the position, rotation and scaling of the bone. In addition, there are IK (Inverse Kinematics, inverse dynamics) constraints in the relationship of the bones, and the motion trajectories of the two bones with IK constraints will also affect each other to achieve bottom-up driving. For example, when doing push-ups, support your body with your hands on the bottom. It can be understood that the IK constraint is the opposite of the IF (Forward Kinematics, forward dynamics) constraint, and the IF constraint is used to achieve top-down driving. For example, the big arm drives the forearm, the thigh drives the calf, and so on.

The display track of the slot, including the slot display track and the slot fader track.

In fact, when the initial information of each animation and the sub-information of each animation are extracted from the analysis animation data, partial information of each frame of each animation can be obtained. For example, for the arm bones in animation music, only the starting position, translation size, rotation angle and duration of a completed action are recorded in the animation. These data are extracted from the analysis animation data. The initial information and The sub-information of each animation can be obtained directly. But where is the position of each bone in each frame, what angle needs to be rotated, whether the slot is displayed, what is the transparency of the slot, and which component is displayed on the slot, it is also necessary to integrate the initial position of the animation, motion trajectory, bone parent-child relationship and The IK constraints of the bones are calculated together.

Specifically, for each animation, the steps of calculating the complete information of each frame of each animation according to the initial information of each animation and the sub-information of each animation include:

The first step is to extract the initial data of the animation from the bone information, slot information, component information and motion trajectory of the animation. The initial data includes the initial position of the bone, the scale of the bone, the rotation angle of the bone, and the component under the slot. The list (for example, the eye is a slot, the pictures of open, squinted and closed eyes are the components under this slot, and the opening and closing of the eyes can be controlled by controlling the display of the first component in the slot) and the relative slot of the component Location.

In the second step, the total number of frames of the animation is extracted from the basic information of the animation, and a list with the same length as the total number of frames is created to save the complete information of each frame of the animation.

The third step is to extract the bone translation track, bone rotation track and bone scaling track of the animation from the motion track of the bone of the animation, according to the bone translation track, bone rotation track and bone scaling track and the initial position of the bone in the initial data, Bone scaling and bone rotation to calculate the position, rotation and actual size of the bone in each frame.

The fourth step is to extract the slot display track of the animation from the slot display track of the animation, and calculate whether the slot is displayed in each frame according to the slot display track, the component list under the slot and the slot display state. Components under the slots shown. It should be noted that the display track refers to the number of the component list under the display slot of the slot in a period of time. For example, if the phone slot is hidden from frames 0 to 17, phone 1 is displayed on frames 17 to 35, phone 2 is displayed on frames 35 to 60, and hidden from frames 60 to 76, then the corresponding duration and display values should be are (17, -1), (18, 0), (25, 1), (16, -1). As above, through the duration and the current display value, it can be calculated whether the slot should be displayed and which slot component is displayed in each animation frame.

The fifth step is to extract the slot gradient track of the animation from the display track of the slot of the animation, read the duration, transparency, and change curve in the slot gradient track, and combine the transparency or initial value at the end of the previous frame of the track. Transparency, calculates the transparency of the slot in each frame. Specifically, the default initial transparency is 100%, which is opaque. Take the phone call animation in the system image animation as an example. In the phone call animation, the transparency of the phone slot is 0 at frames 0 to 17, the transparency of frames 17 to 25 changes from 0 to 100, and the transparency of frames 25 to 52 remains at 100. From 52 to 60 frames, the transparency changes from 100 to 0, and from 60 to 76 frames keep the transparency at 0, then its corresponding duration and transparency should be (17, [0]), (8, [0, 100]), (27 , [100]), (8, [100, 0]), (16, [0]).

The sixth step is to combine the calculated position, rotation angle and actual size of the bone in each frame, whether the slot is displayed, the components under the displayed slot, and the transparency of the slot into the complete information of each frame of the animation. Saved in the list.

According to one embodiment, when the position of the bone in each frame is calculated according to the bone translation track and the initial position of the bone in the initial data, the relative translation distance of the x and y axes in the bone translation track, after the last frame of translation is completed, can be calculated. position and the duration of the translation to calculate the position of the bone in each frame. Among them, in the calculation of the first frame, the initial position of the bone is taken as the position after the translation of the previous frame is completed.

According to an embodiment, when calculating the rotation angle of the bone in each frame according to the bone rotation trajectory and the bone rotation angle in the initial data, the rotation angle and rotation angle in the bone rotation trajectory can be calculated according to the angle change curve in the bone rotation trajectory, the rotation angle and the rotation angle after the end of the previous frame of the trajectory. The duration of , calculates the rotation angle of the bone in each frame. Among them, in the calculation of the first frame, the initial rotation angle of the bone, which is 0 by default, is used as the rotation angle after the end of the trajectory of the previous frame.

It is worth noting that whether it is a bone translation track, a bone rotation track or a bone scaling track, not only linear changes are supported, but curves can be customized. For example, the bone translation trajectory uses the parabola y=x ² , and moves from the first frame (1, 5) to the fifth frame (31, 5), then its position change in each frame should be (1, 5), (2,5), (6,5), (15,5), (31,5) instead of (1,5), (8.5,5), (16,5), (23.5,5), (31, 5). Similarly, the bone rotation track also includes the duration, rotation angle and change curve, which can be calculated by the duration, rotation angle, change curve and the state at the end of the last track (the initial rotation angle of the bone is 0). The rotation angle of the bone in each animation frame. The zoom track is relatively complex. In addition to the duration, change curve, and the zoom size of the x and y dimensions, when calculating the size of the bones of each animation frame, it needs to be calculated in the x and y dimensions together, and finally Gets the actual size of the bones in each frame.

In the above step S104, the step of determining the target animation to be played according to the current scene may include: when the scene changes, judging whether the animation currently being played matches the current scene after the change. If it matches, continue playing the current animation. If it does not match, the target animation to be played corresponding to the current scene is determined according to the current scene. That is to say, the animation switching of the system image is triggered by the scene. For example, when the system is playing music, the system image can monitor the playback status of the music in real time through the OPENAPI interface, and play the music animation. If someone smokes in the car, the system image will monitor the callback of information such as people's behavior and expressions from the perception app (the app is used to identify user behavior and face functions) through the OPENAPI interface, and play the corresponding information according to the person's behavior and expression. Animations, such as a cough animation when the user smokes.

3 , according to one or more embodiments, when a target animation to be played corresponding to the current scene is determined according to the current scene, the animation corresponding to the current scene may be searched first according to the preset correspondence between the scene and the animation. Then, it is judged whether there is an animation corresponding to the current scene in the animation library. If it exists, the animation corresponding to the current scene is used as the target animation. If it does not exist, the default animation is used as the target animation.

Referring to FIG. 4 , according to one or more embodiments, the basic information of each animation may include the total number of frames and the set playing times of each animation. The step of sequentially rendering each frame of animation of the target animation to be played, and playing each frame of the rendered animation frame by frame may include the following steps.

Step S31, acquiring complete information of the next frame of the target animation as the current frame data.

Specifically, the complete information of the next frame of the target animation obtained in this step includes the position, rotation angle and zoom size of the bone in the frame, the display state and transparency of the slot in the frame, and the name of the component displayed by the slot. , component size, relative position, etc.

Step S32, rendering multiple components in the current frame data.

In this step, use openCV to render all the components in the animation frame. Specifically, openCV is used to render the components on it in turn according to the order of the slots, and the absolute position, size, and angle of the components. The slot here has a layer concept. For example, the eye component layer of the system image is higher than the face of the system image, so when rendering, you need to render the face first and then render the eye component, otherwise the eye component will be blocked by the face. components covered.

Step S33, according to the total number of frames of the target animation, determine whether there is a next frame of the target animation, if so, return to step S31, if not, execute step S34.

In step S34, the cumulative number of playbacks of the target animation is incremented by 1, and the current number of playback frames is reset to 0.

In step S35 , it is determined whether the target animation is finished playing according to the accumulated playing times and the set playing times;

Specifically, if the cumulative playing times of the target animation is greater than or equal to the set playing times, it indicates that the target animation has been played, and the playing of the animation is ended. If the cumulative number of playbacks of the target animation is less than the set number of playbacks, the animation will continue to be played from the beginning.

In this embodiment, OpenCV is used to render each frame of animation of the system image animation to be played, thereby reducing the startup delay of the playback engine. Since OpenCV can run on major platforms such as Windows, Android, Maemo, FreeBSD, OpenBSD, iOS, Linux, and Mac OS, it can make the playback engine have a wider scope of application.

According to any optional embodiment of the present invention or a combination of multiple optional embodiments, the embodiment of the present invention can achieve one or more of the following technical effects:
