The following is a detailed description with reference to specific examples. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the application, as detailed in the appended claims. The flow diagrams depicted in the figures are merely exemplary and need not be performed in the order of the steps shown. For example, some steps are parallel, and there is no strict logical relationship between them, so the actual execution order is variable.
Fig. 1 is a schematic flow chart of a motion state identification method according to an embodiment of the present application. In a specific embodiment, the motion state identification method is applied to a motion state identification device or an electronic device equipped with a motion state identification device. As will be described in detail with respect to the flow shown in fig. 2, the motion state identification method may specifically include the following steps:
s101, acquiring a target graph drawing instruction aiming at a target application, and acquiring a first camera position matrix aiming at an application element in a first frame picture in the target graph drawing instruction;
it is understood that, during the running process of the target application, the central processing unit in the electronic device sends the graphics drawing instruction for the target application to the image processor so as to update each frame of application picture of the target application.
Specifically, in the running process of the target application, the central processing unit in the electronic device sends a target graph drawing instruction for the target application to the image processor, and obtains a first camera position matrix of an application element in an application picture for the target application in the target graph drawing instruction.
It should be noted that, in the running process of the target application, when an application screen of the target application needs to be displayed, the central processing unit may call the graphics API to send a graphics drawing instruction to the graphics processor, and perform rendering processing on data of each frame of the application screen, thereby obtaining an application screen after rendering and displaying the application screen on the display screen. Aiming at each frame of application picture, the central processing unit sends a plurality of graphic drawing instructions to the graphic processor, the graphic processor sequentially obtains the graphic drawing instructions sent by the central processing unit and carries out rendering operation, when the graphic processor completely executes the graphic drawing instructions corresponding to one frame of application picture, the rendered application picture is obtained, and then the frame of application picture can be displayed on the display screen.
When the central processing unit sends the graph drawing instruction to the graph processor, the central processing unit stores the graph drawing instruction in a buffer area of the graph processor in consideration of the problem of speed mismatch, and the graph processor sequentially acquires the graph drawing instruction in the buffer area.
And the graphics drawing instruction is a graphics API instruction and is used for calling the graphics processor to render and draw the display picture of the target application. The graphics drawing instruction may be an Application Programming Interface (API) instruction such as OpenGL, openGL ES, directX, or the like.
The application element is one of the elements of the application screen of the target application, and may be, for example, a person, a vehicle, an animal, or a character.
The first camera position matrix is one or more matrixes in a model view projection matrix used by a shader in the graphics processor when the shader renders the application elements in the first frame picture, and can represent the motion state of the application elements in the application picture.
The model view projection matrix, also called MVP matrix, is a matrix obtained by transforming the model matrix, the view matrix and the projection matrix, and can be used for a shader to render and display an application picture with a transformed view angle according to the model view projection matrix. And respectively storing each matrix forming the model view projection matrix in the data transmitted by each graph drawing command, wherein the first camera position matrix is stored in the data transmitted by the target graph drawing command.
In one embodiment, when the target application is first run, the target graphics rendering instructions may be determined by:
before a target graph drawing instruction which is sent to a graph processor by a central processing unit and aims at a target application is obtained, a plurality of frame pictures of the target application when application elements are in different motion states are intercepted, differences between model view projection matrixes corresponding to the application elements in different motion states are compared, and a camera position matrix is determined in a plurality of matrixes forming the model view projection matrixes according to the differences between the model view projection matrixes corresponding to the different motion states. Then, a first buffer area where the camera position matrix is located is determined in each buffer area of the graphics processor, a first buffer area identifier of the first buffer area is determined, the buffer area named by the first buffer area identifier is used as a target buffer area, and a graphics drawing instruction stored in the target buffer area is used as a target graphics drawing instruction.
And in the running process of the target application, monitoring a graph drawing instruction aiming at the target application sent to the graph processor by the central processing unit in real time, and judging whether a cache region stored by the graph drawing instruction is a target buffer region named by the first buffer region identifier. And if the cache region stored by the graph drawing instruction is determined to be the target buffer region named by the first buffer region identifier, determining the graph drawing instruction to be the target graph drawing instruction, and acquiring a first camera position matrix aiming at the application element in the first frame picture in the target graph drawing instruction.
In one embodiment, when the target application is not first run, the target graphics rendering instructions may be determined by:
and determining a second buffer area with the same size as the first buffer area in each buffer area of the graphics processor, determining a second buffer area identifier of the second buffer area, taking the buffer area named by the second buffer area identifier as a target buffer area, and taking the graphics drawing instruction stored in the target buffer area as a target graphics drawing instruction.
And in the running process of the target application, monitoring a graph drawing instruction sent to the graph processor by the central processing unit in real time, and judging whether a cache region stored by the graph drawing instruction is a target buffer region named by the second buffer region identifier. And if the cache region stored by the graph drawing instruction is determined to be the target buffer region named by the second buffer region identifier, determining the graph drawing instruction to be the target graph drawing instruction, and acquiring a first camera position matrix aiming at the application element in the first frame picture in the target graph drawing instruction.
S102, acquiring a second camera position matrix of application elements in a recorded second frame picture, wherein the second frame picture is obtained before the first frame picture based on target application and the number of frames separated from the first frame picture is less than or equal to a preset number of frames;
specifically, a second camera position matrix of application elements in a recorded second frame picture is obtained, the second frame picture is a frame picture before a first frame picture in the running process of the target application, the number of frames between the second frame picture and the first frame picture is less than or equal to a preset number of frames, and the second camera position matrix is a camera position matrix corresponding to the application elements in the second frame picture obtained before the first camera position matrix of the first frame picture is obtained.
S103, determining the motion state of the application element based on the first camera position matrix and the second camera position matrix.
Specifically, a difference between a first camera position matrix corresponding to an application element in the first frame picture and a second camera position matrix corresponding to an application element in the second frame picture is calculated. And if the difference value between the first camera position matrix and the second camera position matrix is zero, namely the application element is not moved from the second frame picture to the first frame picture, determining that the motion state of the application element is in a static state, and if the difference value between the first camera position matrix and the second camera position matrix is not zero, namely the application element is moved from the second frame picture to the first frame picture, determining that the motion state of the application element is in a moving state.
In one embodiment, after determining the motion state of the application element, the picture display quality of the target application may be adjusted based on the motion state of the application element.
Optionally, if it is determined that the motion state of the application element is the moving state, the picture display quality of the current picture is reduced based on the load reduction technique, and if it is determined that the motion state of the application element is the static state, the picture display quality of the current picture is kept unchanged.
It can be understood that, when the motion state of the application element is a static state, the change of each frame of picture displayed by the target application is small or unchanged, and when each frame of picture is rendered and displayed, the computing pressure of the central processing unit and the graphic processor is small, and the pause phenomenon caused by insufficient hardware performance can not occur, so that the picture display quality of the target application does not need to be reduced, and a good display effect can be maintained to meet the needs of users. When the motion state of the application element is a moving state, each frame of picture displayed in the moving target application of the application element is changed rapidly, at this time, the change of each frame of picture displayed by the target application is large, the calculation pressure of the central processing unit and the graphic processor when each frame of picture is rendered and displayed is large, and a pause phenomenon caused by insufficient hardware performance is easy to occur.
In one or more embodiments of the present application, in the running process of a target application, a target graphics drawing instruction for the target application, which is sent from a central processing unit to a graphics processor, is obtained, a first camera position matrix for an application element in a first frame picture in the target graphics drawing instruction is obtained, then a second camera position matrix for the application element in a recorded second frame picture is obtained, the second frame picture is a frame picture which is obtained before the first frame picture based on the target application and has a frame number which is less than or equal to a preset frame number and is separated from the first frame picture, and finally a motion state of the application element is determined based on the first camera position matrix and the second camera position matrix.
In one embodiment, the target buffer in which the target graphics drawing instruction is stored also needs to be determined prior to fetching the target graphics drawing instruction. Referring to fig. 2, a schematic flow chart of a motion state identification method provided in an embodiment of the present application is shown when a target application is first run. As shown in fig. 2, the motion state identification method may include the steps of:
s201, intercepting a plurality of frame pictures when application elements in target application are in different motion states, and acquiring difference data between model view projection matrixes of each frame picture in the plurality of frame pictures;
specifically, when the target application runs for the first time, a plurality of frame images of the target application with application elements in different motion states are captured, and differences between model view projection matrixes corresponding to the application elements in the frame images are compared to obtain difference data between the model view projection matrixes.
For example, a frame picture in which an application element in the target application is in a static state and a frame picture in which the application element in the target application is in a running state are captured, model view projection matrices corresponding to the application elements in the two frame pictures are compared, and difference data between the two model view projection matrices is obtained.
S202, determining a camera position matrix in a plurality of matrixes forming a model view projection matrix based on difference data;
it can be understood that when the application element is in different motion states, the model view projection matrices used by the shader for rendering and displaying the target element are different, difference data between the model view projection matrices is obtained by comparing differences between the model view projection matrices in which the application element is in different motion states, and a camera position matrix for representing the motion state of the application element can be determined from the difference data among a plurality of matrices constituting the model view projection matrices.
S203, determining a first buffer area where the camera position matrix is located in a buffer area set, wherein each buffer area in the buffer area set is used for storing a graphic drawing instruction for a target application;
s204, taking the first buffer area as a target buffer area, and taking the graph drawing instruction stored in the target buffer area as a target graph drawing instruction;
and each buffer zone in the buffer zone set is each buffer zone in the graphics processor and is used for storing the graphics drawing instruction which is sent to the graphics processor by the central processing unit and aims at the target application.
Specifically, in steps S203 to S204, after the camera position matrix representing the motion state of the application element is determined from the plurality of matrices constituting the model view projection matrix, a first buffer area in which the camera position matrix is located is determined in each buffer area of the graphics processor, the first buffer area is used as a target buffer area, and the graphics drawing instruction stored in the target buffer area is used as a target graphics drawing instruction. The target graph drawing instruction is a graph drawing instruction carrying a camera position matrix.
It should be appreciated that the camera position matrix used to represent the motion state of the application element is not obvious when it is first run, i.e. the electronic device running the target application does not know which matrix can represent the motion state of the application element in the initial phase, the camera position matrix being obtained by comparing the differences between the model view projection matrices for which the application element is in different motion states. For a target element in the same target application, the camera position matrix used for representing the motion state of the application element does not change any more, so that the steps of sequentially determining the camera position matrix only need to be executed when the target application runs for the first time.
The camera position matrix is data transmitted in a graph drawing instruction sent by the central processing unit to the graph processor, after the camera position matrix is determined, a first buffer area stored in the camera position matrix needs to be located, the first buffer area serves as a target buffer area, and the graph drawing instruction stored in the target buffer area serves as a target graph drawing instruction, so that the target graph drawing instruction stored in the buffer area can be monitored in the running process of target application.
It should be noted that, from the starting operation of the target application to the ending operation of the target application, in a complete operation process, the buffer area stored by the target graphic drawing instruction carrying the camera position matrix is not changed. That is, after the target buffer area is determined, the graphics drawing instruction stored in the target buffer area is the target graphics drawing instruction carrying the camera position matrix.
S205, monitoring a graph drawing instruction for the target application in real time, and judging whether a cache region stored by the graph drawing instruction is a target buffer region;
s206, if the cache region stored by the graph drawing instruction is determined to be the target buffer region, determining the graph drawing instruction to be the target graph drawing instruction;
in step S205 to step S206, a graphics drawing instruction sent from the central processing unit to the graphics processing unit is monitored in real time, whether a buffer identifier of a buffer area stored in the graphics drawing instruction is the same as a target buffer identifier of a target buffer area is determined, and if the buffer identifier of the buffer area stored in the graphics drawing instruction is the same as the target buffer area, the cache area stored in the graphics drawing instruction is determined as the target buffer area, and the graphics drawing instruction is determined as the target graphics drawing instruction carrying the camera position matrix.
The buffer identification may be a name identification of the buffer or a size identification of the buffer.
Optionally, if it is determined that the cache region stored in the graphics drawing instruction is not the target buffer region, it is determined that the graphics drawing instruction is not the target graphics drawing instruction.
S207, acquiring a first camera position matrix aiming at application elements in a first frame picture in a target graph drawing instruction;
specifically, after the target graphic drawing instruction is determined, a first camera position matrix for the application element in the first frame of the picture is acquired in data passed by the target graphic drawing instruction based on a HOOK function.
The first frame picture is an application picture of a target application rendered and displayed by the graphics processor based on the target graphics drawing instruction.
S208, acquiring a second camera position matrix of application elements in a recorded second frame picture, wherein the second frame picture is obtained before the first frame picture based on target application, and the number of frames separated from the first frame picture is less than or equal to a preset number of frames;
specifically, please refer to step S208 for a detailed description of step S102 in another embodiment, which is not repeated herein.
S209, calculating a difference value between the first camera position matrix and the second camera position matrix;
s210, if the difference value is zero, determining that the motion state of the application element is a static state;
s211, if the difference is not zero, determining that the motion state of the application element is a moving state;
alternatively, the movement state may include a walking state, a running state, and a driving state. In one embodiment, the moving speed of the application element may also be calculated based on a time interval between the first frame picture and the second frame picture and a difference value between the first camera position matrix and the second camera position matrix. If the moving speed of the application element is larger than zero and smaller than a first speed threshold value, determining that the motion state of the application element is a walking state; if the moving speed of the application element is greater than the first speed threshold and less than the second speed threshold, determining that the motion state of the application element is a running state; and if the moving speed of the application element is greater than the second speed threshold value, determining that the motion state of the application element is a driving state.
S212, if the motion state of the application element is determined to be the moving state, reducing the picture display quality of the current picture based on a load reduction technology;
it can be understood that, when the motion state of the application element is a moving state, each frame displayed in the moving target application along with the application element changes rapidly, at this time, the change of each frame displayed by the target application is large, the computing pressure of the central processing unit and the graphics processing unit when rendering and displaying each frame is large, and a pause phenomenon caused by insufficient hardware performance is easy to occur, so that the image display quality of the target application can be reduced based on a load reduction technology to relieve the computing pressure of the central processing unit and the graphics processing unit, and the target application is kept running smoothly.
The load reduction technology can be GPU load reduction technology and variable resolution rendering technology.
Alternatively, the movement state may include a walking state, a running state, and a driving state. In one embodiment, the game image quality is reduced to a first resolution based on a load reduction technique if the motion state of the application element is determined to be a walking state, the game image quality is reduced to a second resolution based on the load reduction technique if the motion state of the application element is determined to be a running state, and the game image quality is reduced to a third resolution based on the load reduction technique if the motion state of the application element is determined to be a driving state, the first resolution being greater than the second resolution, and the second resolution being greater than the third resolution.
And S213, if the motion state of the application element is determined to be a static state, keeping the picture display quality of the current picture unchanged.
It can be understood that, when the motion state of the application element is a static state, the change of each frame of picture displayed by the target application is small or unchanged, and when each frame of picture is rendered and displayed, the computing pressure of the central processing unit and the graphic processor is small, and the pause phenomenon caused by insufficient hardware performance can not occur, so that the picture display quality of the target application does not need to be reduced, and a good display effect can be maintained to meet the needs of users.
In the embodiment of the application, when a target application runs for the first time, a plurality of frame pictures of the target application when application elements are in different motion states are intercepted, a camera position matrix is determined based on difference data between model view projection matrixes of each frame picture in the plurality of frame pictures, a target buffer area corresponding to the camera position matrix is determined, and a graph drawing instruction stored in the target buffer area is a target graph drawing instruction carrying the camera position matrix. And then monitoring a target graph drawing instruction stored in a target buffer area in real time, acquiring a camera position matrix used for identifying the motion state of the application element in the target graph drawing instruction based on a HOOK function, determining the motion state of the application element by calculating the difference value of a first camera position matrix of the application element in a first frame of picture and a second camera position matrix of the application element in a second frame of picture, under the condition that a target application client does not send any information such as action, time and the like of the application element, judging the motion state of the application element in the target application by detecting the camera position matrix between different frames in the running process of the target application, adjusting the picture display quality of the target application according to the motion state of the application element, avoiding the problem of jamming caused in the rapid moving process of the application element, and ensuring smooth running of the target application.
In one embodiment, when the target application is not running for the first time, the position of the target buffer stored in the camera position matrix for representing the motion state of the application element may change, but the size of the target buffer may not change. Thus, when the target application is not first run time, the target buffer stored by the camera position matrix needs to be re-determined based on the first run-time determined first buffer size. Please refer to fig. 3, which is a flowchart illustrating a motion state identification method according to an embodiment of the present disclosure. As will be explained in detail with respect to the flow shown in fig. 3, the motion state identification method may include the following steps:
s301, determining a second buffer area with the same size as the first buffer area in the buffer area set;
