实施例一Example 1
本公开实施例提供一种数据处理方法，如图1所示，该视频数据处理方法包括以下步骤：An embodiment of the present disclosure provides a data processing method. As shown in FIG. 1 , the video data processing method includes the following steps:
101、获取目标图像数据及对应的目标鼠标数据。101. Acquire target image data and corresponding target mouse data.
鼠标数据包括：鼠标的状态数据和鼠标的位置数据；鼠标的状态数据，包括鼠标滚轮信息和鼠标按键信息。Mouse data includes: mouse state data and mouse position data; mouse state data, including mouse wheel information and mouse button information.
在获取目标图像数据及当前鼠标位置数据，之前包括：Before obtaining the target image data and the current mouse position data, include:
获取目标图像数据对应的上一帧图像数据和上一帧图像数据中对应的鼠标数据；Obtain the previous frame of image data corresponding to the target image data and the mouse data corresponding to the previous frame of image data;
当上一帧图像数据和目标图像数据不一致时，确定上一帧图像数据为预设图像数据，鼠标数据为预设鼠标数据。When the image data of the previous frame is inconsistent with the target image data, it is determined that the image data of the previous frame is the preset image data, and the mouse data is the preset mouse data.
当上一帧图像数据和目标图像数据一致时，则确定上一帧图像数据不是预设图像数据，结束视频数据处理进程。When the image data of the previous frame is consistent with the target image data, it is determined that the image data of the previous frame is not the preset image data, and the video data processing process is ended.
在可选实施例中，当预设图像数据和目标图像数据不一致时，包括：In an optional embodiment, when the preset image data is inconsistent with the target image data, it includes:
获取目标图像数据中至少一个目标宏块图像数据及对应的位置信息；Obtain at least one target macroblock image data and corresponding position information in the target image data;
根据位置信息，获取上一帧图像数据中对应位置的宏块图像数据；According to the position information, obtain the macroblock image data of the corresponding position in the previous frame of image data;
当目标宏块图像数据与上一帧图像数据中对应的对应位置的宏块图像数据一致时，确认目标图像数据与上一帧图像数据一致。When the target macroblock image data is consistent with the macroblock image data at the corresponding position in the previous frame of image data, it is confirmed that the target image data is consistent with the previous frame of image data.
102、根据目标鼠标数据和预设鼠标数据，生成比较数据。102. Generate comparison data according to the target mouse data and the preset mouse data.
比较数据，包括目标鼠标与预设鼠标之间坐标差数据；用于指示目标鼠标与预设鼠标的位置信息是否一致，即两个鼠标是否重合。The comparison data includes coordinate difference data between the target mouse and the preset mouse; it is used to indicate whether the position information of the target mouse and the preset mouse is consistent, that is, whether the two mice overlap.
在可选实施例中，目标鼠标与预设鼠标之间坐标差数据，包括：In an optional embodiment, the coordinate difference data between the target mouse and the preset mouse includes:
当坐标差数据不为零时，根据目标鼠标数据和比较数据，生成目标运动向量。When the coordinate difference data is not zero, the target motion vector is generated according to the target mouse data and the comparison data.
当坐标差数据不为零时，根据目标鼠标数据和比较数据，生成目标运动向量，该坐标差数据用于指示目标鼠标坐标与预设鼠标坐标相比是否没有发生变化，即目标鼠标坐标与预设鼠标坐标是否重合。When the coordinate difference data is not zero, the target motion vector is generated according to the target mouse data and the comparison data. The coordinate difference data is used to indicate whether the target mouse coordinates have not changed compared with the preset mouse coordinates, that is, the target mouse coordinates are different from the preset mouse coordinates. Set whether the mouse coordinates coincide.
当计算结果不为零时，根据目标鼠标数据中的状态数据包括鼠标滚轮的状态，若鼠标滚轮状态没有发生变化，则使用运动搜索算法来计算运动向量，运动搜索方法，即可将目标图像数据分成若干块或宏块，并设法搜索出每个块或宏块在邻近帧图像中的位置，并得出两者之间的空间位置的相对偏移量，得到的相对偏移量即，目标运动向量。When the calculation result is not zero, according to the state data in the target mouse data, including the state of the mouse wheel, if the state of the mouse wheel does not change, use the motion search algorithm to calculate the motion vector. The motion search method can convert the target image data into Divide into several blocks or macroblocks, and try to search for the position of each block or macroblock in the adjacent frame image, and obtain the relative offset of the spatial position between the two, the obtained relative offset is the target motion vector.
103、根据目标鼠标数据和比较数据，生成目标运动向量103. Generate the target motion vector according to the target mouse data and the comparison data
在可选实施例中，根据目标鼠标数据和比较数据，生成目标运动向量，包括：In an optional embodiment, the target motion vector is generated according to the target mouse data and the comparison data, including:
若目标鼠标数据中的状态数据指示为拖拽状态，则获取目标鼠标的坐标数据，坐标数据包括，x轴坐标数据值x、y轴坐标数据值y；该拖拽状态包括，目标鼠标按下并移动的状态；If the state data in the target mouse data indicates a drag state, the coordinate data of the target mouse is obtained, and the coordinate data includes the x-axis coordinate data value x and the y-axis coordinate data value y; the drag state includes that the target mouse is pressed down and moving state;
根据坐标数据，获取(x，y)坐标点数据、(0，y)坐标点数据和(x，0)坐标点数据，并生成目标运动向量。例如，目标鼠标的坐标数据为(4，5)，即x轴坐标数据值为4、y轴坐标数据值为5，则分别获取(x，y)坐标点数据为(4,5)、(0，y)坐标点数据为(0,5)和(x，0)坐标点数据(0，4)，生成目标运动向量。According to the coordinate data, the (x, y) coordinate point data, the (0, y) coordinate point data and the (x, 0) coordinate point data are acquired, and the target motion vector is generated. For example, if the coordinate data of the target mouse is (4, 5), that is, the value of the x-axis coordinate data is 4 and the value of the y-axis coordinate data is 5, the data of the (x, y) coordinate points obtained are (4, 5), ( 0, y) coordinate point data is (0, 5) and (x, 0) coordinate point data (0, 4) to generate a target motion vector.
在可选实施例中，根据目标鼠标数据和比较数据，生成目标运动向量，包括：In an optional embodiment, the target motion vector is generated according to the target mouse data and the comparison data, including:
若目标鼠标数据中的状态数据指示为非拖拽状态，且目标鼠标数据中的状态数据指示为上下滚动状态时，获取目标鼠标的坐标数据，坐标数据包括，x轴坐标数据值x、y轴坐标数据值y；If the state data in the target mouse data indicates a non-drag state, and the state data in the target mouse data indicates a scrolling state, the coordinate data of the target mouse is obtained, and the coordinate data includes the x-axis coordinate data values x, y-axis coordinate data value y;
当目标图像数据与预设图像数据不一致时，根据目标鼠标的坐标数据，获取(y，0)坐标点数据，并生成目标运动向量。因为当目标鼠标数据中的状态为上下滚动时，对应的目标图像数据也即在上下方位发生相应变化，此时的目标运动向量仅需获取目标鼠标的坐标数据中y轴坐标数据值y。When the target image data is inconsistent with the preset image data, the (y, 0) coordinate point data is acquired according to the coordinate data of the target mouse, and the target motion vector is generated. Because when the state in the target mouse data is scrolling up and down, the corresponding target image data also changes correspondingly in the up and down orientation, and the target motion vector at this time only needs to obtain the y-axis coordinate data value y in the coordinate data of the target mouse.
在具体的实施例中，当目标图像数据与预设图像数据不一致时，获取目标图像数据所属窗口的应用类型，根据应用类型和目标鼠标数据来产生运动向量(0,y)，即根据y＝ε·S获取目标运动向量，上述公式中：ε代表预设参数，该预设参数值根据目标图像数据的窗口应用类型决定，同一应用类型的经验参数可能会有多个，如word应用类型、PDF应用类型；S代表本方法中触发鼠标滚轮事件返回的代表鼠标滚轮移动方向和大小的值。本方法根据目标鼠标的按键状态、目标鼠标垂直方向的偏移量滚轮偏移量确定的目标运动向量。In a specific embodiment, when the target image data is inconsistent with the preset image data, the application type of the window to which the target image data belongs is obtained, and the motion vector (0, y) is generated according to the application type and the target mouse data, that is, according to y= ε·S obtains the target motion vector. In the above formula: ε represents the preset parameter. The preset parameter value is determined according to the window application type of the target image data. There may be multiple experience parameters of the same application type, such as word application type, PDF application type; S represents the value returned by triggering the mouse wheel event in this method and representing the movement direction and size of the mouse wheel. The method determines the target motion vector according to the button state of the target mouse and the offset amount of the target mouse in the vertical direction of the scroll wheel.
在可选实施例中，根据目标鼠标数据和比较数据，生成目标运动向量，包括：In an optional embodiment, the target motion vector is generated according to the target mouse data and the comparison data, including:
若状态数据指示为非拖拽状态，且状态数据指示，鼠标滚轮点击后没有再次点击或者没有点击其它按键时，获取目标鼠标的坐标数据，坐标数据包括，x轴坐标数据值x、y轴坐标数据值y；If the state data indicates a non-drag state, and the state data indicates that the mouse wheel is not clicked again or other buttons are not clicked, the coordinate data of the target mouse is obtained, and the coordinate data includes the x-axis coordinate data value x and y-axis coordinates data value y;
当目标图像数据与预设图像数据不一致时，根据目标鼠标的坐标数据，获取(y，0)坐标点数据，并生成目标运动向量。When the target image data is inconsistent with the preset image data, the (y, 0) coordinate point data is acquired according to the coordinate data of the target mouse, and the target motion vector is generated.
在可选实施例中，根据目标鼠标数据和比较数据，生成目标运动向量之后，还包括：In an optional embodiment, after generating the target motion vector according to the target mouse data and the comparison data, the method further includes:
获取目标图像数据中至少一个目标宏块图像数据及对应的目标位置数据；Obtain at least one target macroblock image data and corresponding target position data in the target image data;
获取目标位置数据获取预设图像数据中对应位置的预设宏块图像数据；obtaining target position data to obtain preset macroblock image data at a corresponding position in the preset image data;
根据目标运动向量移动目标宏块图像数据后若与预设宏块图像数据一致，则存储目标运动向量。After moving the target macroblock image data according to the target motion vector, if the target macroblock image data is consistent with the preset macroblock image data, the target motion vector is stored.
在可选实施例中，生成目标运动向量之后，枚举所有目标图像数据变化区域中的宏块，使用运动向量将目标图像数据中的宏块，即目标宏块平移后和预设图像数据中对应位置的宏块进行数据比较。如果比较二者数据相同，就可以认为目标宏块可以通过运动向量从预设图像数据中得到，从而可以减少获取运动向量的计算量，提高数据处理效率。In an optional embodiment, after generating the target motion vector, enumerate all macroblocks in the target image data change region, and use the motion vector to convert the macroblocks in the target image data, that is, the target macroblock after translation and the preset image data. Data comparison is performed on the macroblocks at the corresponding positions. If the two data are the same, it can be considered that the target macroblock can be obtained from the preset image data through the motion vector, thereby reducing the amount of calculation for obtaining the motion vector and improving the data processing efficiency.
在可选实施例中，存储目标运动向量后，获取目标图像数据对应的目标位置数据和目标运动向量，生成目标数据。该目标数据用于指示，视频数据压缩处理上一帧图像数据与当前图像数据的时，可以根据该目标数据将上一帧图像数据平移后得到当前图像数据；即通过目标数据中的位置数据确定上一帧图像数据对应目标位置的预设宏块图像数据，通过目标数据中的目标运动向量确定预设宏块图像数据需平移的运动向量可得到当前图像数据。In an optional embodiment, after the target motion vector is stored, target position data and target motion vector corresponding to the target image data are acquired to generate target data. The target data is used to indicate that when the video data is compressed to process the previous frame of image data and the current image data, the current image data can be obtained by shifting the previous frame of image data according to the target data; that is, the position data in the target data determines The image data of the previous frame corresponds to the preset macroblock image data of the target position, and the current image data can be obtained by determining the motion vector of the preset macroblock image data to be translated by the target motion vector in the target data.
本公开实施例提供的数据处理方法，通过获取目标图像数据及对应的目标鼠标数据；并根据目标鼠标数据和预设鼠标数据，生成比较数据；最后根据目标鼠标数据和比较数据，生成目标运动向量。本公开通过获取当前图像数据中的鼠标数据来计算两帧图像数据间运动向量，从而避免了在视频压缩过程中逐块计算运动向量的大量计算损耗，提高了数据处理效率。The data processing method provided by the embodiment of the present disclosure obtains target image data and corresponding target mouse data; generates comparison data according to the target mouse data and preset mouse data; and finally generates a target motion vector according to the target mouse data and the comparison data . The present disclosure calculates the motion vector between two frames of image data by acquiring the mouse data in the current image data, thereby avoiding a large amount of computational loss in calculating the motion vector block by block in the video compression process, and improving the data processing efficiency.
