[0053] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0054] Figure 1 FIG. 1 is a schematic diagram of an implementation environment of a method for processing seismic data provided in an embodiment of the present application, such as Figure 1 As shown, the implementation environment includes: a terminal device 101. The terminal device 101 is used to execute the seismic data processing method provided in the embodiment of the present application.

[0055] Optionally, the terminal device 101 may be any electronic device that can interact with a user through one or more methods such as a keyboard, a touchpad, a remote control, voice interaction, or a handwriting device. For example, a PC (Personal Computer), a mobile phone, a smart phone, a PDA (Personal Digital Assistant), a wearable device, a PPC (Pocket PC), a tablet computer, a smart car computer, a smart TV, a smart speaker, a smart watch, etc.

[0056] Terminal device 101 may generally refer to one of multiple terminal devices. This embodiment uses terminal device 101 as an example. Those skilled in the art will appreciate that the number of terminal devices may be greater or lesser. For example, there may be only one terminal device, or there may be dozens, hundreds, or even more terminal devices. This embodiment of the application does not limit the number or type of terminal devices.

[0057] Those skilled in the art should understand that the above-mentioned terminal device 101 is only an example. Other existing or future terminal devices 101, if applicable to this application, should also be included in the scope of protection of this application and are included here by reference.

[0058] The present invention provides a method for processing seismic data. Figure 1 The implementation environment shown is Figure 2 As an example, the flowchart of a method for processing seismic data provided in the embodiment of the present application is shown. The method can be performed by Figure 1 The terminal device 101 in the embodiment is executed. Figure 2 As shown, the method includes the following steps 201 to 204.

[0059] In step 201, seismic files of a seismic wave field at multiple moments in a reference time period are obtained.

[0060] The seismic wavefield refers to the space in which seismic waves propagate. Seismic waves are vibrations that propagate from the earthquake's epicenter and are elastic waves that radiate from the epicenter. Seismic waves can be divided into three types based on their propagation: longitudinal (P) waves, transverse (S) waves, and surface (L) waves. P-waves are propulsion waves that travel through the Earth's crust at a speed of 5.5-7 km / s. They are the first to reach the epicenter, causing the ground to vibrate up and down and are less destructive. S-waves are shear waves that travel through the Earth's crust at a speed of 3.2-4.0 km / s. They are the second to reach the epicenter, causing the ground to shake back and forth and left and right and are more destructive. Surface waves are hybrid waves generated by the collision of longitudinal and transverse waves on the Earth's surface. They have large wavelengths and strong amplitudes, propagating only along the Earth's surface and are the primary cause of severe damage to buildings.

[0061] In an exemplary embodiment of the present application, a terminal device stores seismic files of a seismic wave field at multiple moments in a reference time period. The reference time period is any time period, and the multiple moments in the reference time period can be individual moments in the reference time period, or can be at least two moments in the reference time period, which is not limited in the embodiment of the present application. The terminal device extracts seismic files of a seismic wave field at multiple moments in the reference time period from its storage space. The seismic file of the seismic wave field at any moment in the reference time period includes seismic data of multiple points included in the seismic wave field at any moment. The multiple points included in the seismic wave field are points located in the seismic wave field. The seismic data includes amplitude information and related information. Among them, the amplitude information is a physical quantity representing the range and intensity of vibration.

[0062] Optionally, the seismic file of the seismic wavefield at any moment in the reference time period is a file storing seismic data in the SEG (Society of Exploration Geophysicists) format. That is, the seismic file of the seismic wavefield at any moment in the reference time period is a SEG-Y file.

[0063] In step 202, for any moment among the multiple moments included in the reference time period, multiple first points are determined from the multiple points included in the seismic wavefield according to amplitude information of each point included in the seismic wavefield at any moment.

[0064] In one possible implementation, before determining multiple first points from the multiple points in the seismic wavefield based on the amplitude information of each point in the seismic wavefield at any moment, it is necessary to read trace header information from the seismic file of the seismic wavefield at any moment, manually perform trace header analysis on the trace header information, and, upon confirming the accuracy of the trace header information, determine multiple first points from the multiple points in the seismic wavefield based on the amplitude information of each point in the seismic wavefield at any moment. The seismic file of the seismic wavefield at any moment is a SEG-Y file, which consists of three parts. The first part is the EBCDIC (Extended Binary Coded Decimal Interchange Code) file header, consisting of 40 cards, which stores information describing the seismic data volume. The second part is the binary file header, which stores key information describing the SEG-Y file, including the SEG-Y file format, number of sampling points, sampling interval, and measurement units. This information is generally stored in a fixed location within the binary file header. The third part is the actual seismic trace. Each seismic trace contains 240 bytes of trace header information and seismic trace data. The trace header generally stores information such as the line number, trace number, number of sampling points, and geodetic coordinates of the corresponding seismic trace, but the locations of some key parameters are not fixed.

[0065] The process of determining multiple first points from multiple points included in the seismic wave field based on amplitude information of each point included in the seismic wave field at any moment includes: determining first amplitude information and second amplitude information based on the amplitude information of each point included in the seismic wave field at any moment; determining third amplitude information based on the first amplitude information and a first amplitude proportional coefficient, and determining fourth amplitude information based on the second amplitude information and the second amplitude proportional coefficient; and determining, from the multiple points included in the seismic wave field, a point whose amplitude information at any moment is between the third amplitude information and the fourth amplitude information as a first point.

[0066] The first amplitude information is the maximum value of the amplitude information for each point at any moment, and the second amplitude information is the minimum value of the amplitude information for each point at any moment. The third amplitude information is smaller than the first amplitude information, the fourth amplitude information is larger than the second amplitude information, and the second amplitude scaling factor is larger than the first amplitude scaling factor. For example, the first amplitude scaling factor is 0.8, and the second amplitude scaling factor is 1.2.

[0067] In one possible implementation, the process of determining multiple first points from among the multiple points in the seismic wavefield based on the amplitude information of each point in the seismic wavefield at any moment may also include: determining a reference amplitude interval; and selecting, among the various points in the seismic wavefield, the points whose amplitude information at any moment falls within the reference amplitude interval as the first points. The reference amplitude interval is set based on experience or adjusted according to the implementation environment, and is not limited in this embodiment of the present application. For example, the reference amplitude interval is [50, 100].

[0068] In step 203, a seismic image of the seismic wave field at any moment is acquired based on the relevant information of the plurality of first points at any moment.

[0069] The seismic image of the seismic wave field at any moment is used to indicate the seismic wave propagation characteristics of the seismic wave field at any moment.

[0070] In one possible implementation, the relevant information includes position information, color information, and transparency information. After determining a first point from among the multiple points included in the seismic wavefield in step 202, the process of obtaining a seismic image of the seismic wavefield at any moment based on the relevant information of the multiple first points at any moment includes: performing deduplication processing on the multiple first points based on the color information and transparency information of the multiple first points at any moment to obtain multiple second points; and obtaining a seismic image of the seismic wavefield at any moment based on the position information, color information, and transparency information of the multiple second points at any moment. The color information of the multiple second points at any moment is different, and the transparency information of the multiple second points at any moment is also different.

[0071] Optionally, multiple first points are compressed using a discrete cosine transform (DCT) compression algorithm or a wavelet transform (WT) compression algorithm to obtain multiple second points. The discrete cosine transform (DCT) compression algorithm is a transform related to the Fourier transform (FT), similar to the discrete Fourier transform (DFT). The wavelet transform (WT) compression algorithm is a new transform analysis method that inherits and develops the localization concept of the short-time Fourier transform (STFT) while overcoming the problem of window size being invariant with frequency. It can provide a frequency-dependent "time-frequency" window, making it an ideal tool for signal time-frequency analysis and processing. Its main features include the ability to highlight specific features through transformation, enabling localized analysis of time (space) frequency, and gradually refining the signal (function) at multiple scales through scaling and translation operations, ultimately achieving time segmentation at high frequencies and frequency segmentation at low frequencies. It can automatically adapt to the requirements of time-frequency signal analysis, allowing for focus on any detail of the signal.

[0072] In one possible implementation, the process of obtaining a seismic image of a seismic wave field at any moment based on the position information, color information, and transparency information of multiple second points at any moment includes: grouping the multiple second points based on the position information of the multiple second points at any moment to obtain a reference number of groups, any group including at least one second point; and obtaining a seismic image of the seismic wave field at any moment based on the position information, color information, and transparency information of the multiple second points included in any group of the reference number of groups.

[0073] The process of grouping the plurality of second points based on the position information of the plurality of second points at any moment to obtain a reference number of groups includes: dividing the plurality of second points using an octree structure to obtain eight groups; or dividing the plurality of second points using a quadtree structure to obtain four groups. Alternatively, based on the position information of the plurality of second points at any moment, clustering the plurality of second points using a K-MAENS (K-means) clustering algorithm to obtain K groups, where K is a positive integer greater than 1.

[0074] Optionally, after obtaining a reference number of groups, the reference number of groups can be stored in the storage space of the terminal device, so that any group can be extracted from the reference number of groups later, and the seismic image of the seismic wave field at any moment can be obtained according to the position information, color information and transparency information of the multiple second points included in any group at any moment.

[0075] In one possible implementation, the process of obtaining a seismic image of a seismic wave field at any moment based on the position information, color information, and transparency information of multiple second points included in any group of a reference number of groups at any moment includes: a display window is displayed in a display interface of a terminal device, and based on the position information of multiple second points included in any group at any moment, perspective rendering is performed on the position corresponding to the position information in the display window to obtain a reference image of the seismic wave field at any moment; based on the color information and transparency information of multiple second points included in any group at any moment, perspective rendering is performed on the reference image of the seismic wave field at any moment to obtain a seismic image of the seismic wave field at any moment.

[0076] The process of performing perspective rendering on the positions corresponding to the position information in the display window based on the position information of the multiple second points included in any group at any moment to obtain a reference image of the seismic wave field at any moment includes: rendering the color of the positions indicated by the position information of the multiple second points included in any group at any moment as a reference color and rendering the transparency as a reference transparency to obtain a reference image of the seismic wave field at any moment. Optionally, the reference color and reference transparency are set based on experience or adjusted according to the implementation environment, which is not limited in this embodiment of the present application. Exemplarily, the reference color is red and the reference transparency is 30%.

[0077] According to the color information and transparency information of the multiple second points included in any group at any time, the reference image of the seismic wave field at any time is perspective rendered to obtain the seismic image of the seismic wave field at any time. The process includes: rendering the color of each point in the reference image of the seismic wave field at any time displayed in the display window to the color corresponding to the color information of each point, rendering the transparency to the transparency corresponding to the transparency information of each point, obtaining a first image, calling an image capture tool to capture the first image displayed in the display window, and using the captured image as the seismic image of the seismic wave field at any time. Among them, the image capture tool can be any image capture tool, and the embodiment of the present application does not limit this. The seismic image of the seismic wave field at any time can be a seismic image in any format, and the embodiment of the present application does not limit this. Exemplarily, the seismic image of the seismic wave field at any time is an image in JPEG (Joint Photographic Experts Group) format, or the seismic image of the seismic wave field at any time is an image in PNG (Portable Network Graphics) format.

[0078] like Figure 3 This is a schematic diagram of a seismic image of a seismic wave field at any moment provided by an embodiment of the present application.

[0079] Optionally, the seismic images of the seismic wave field at each moment are obtained in the manner of steps 202 to 203. Figure 4 This is a schematic diagram of seismic images of a seismic wave field at various moments provided in an embodiment of the present application. Figure 4The data includes seismic images corresponding to the seismic wave field at 77 moments. The seismic images of the seismic wave field at each moment are acquired in a reference time sequence. For example, the seismic image of the seismic wave field at an earlier moment is acquired first, and then the seismic image of the seismic wave field at a later moment is acquired. For another example, the seismic image of the seismic wave field at a later moment is acquired first, and then the seismic image of the seismic wave field at a later moment is acquired. The embodiments of the present application do not limit the reference time sequence.

[0080] In one possible implementation, after obtaining a seismic image of the seismic wave field at any moment, the seismic image of the seismic wave field at any moment displayed in the display window is removed to free up memory space of the terminal device so that the seismic image of the seismic wave field at the next moment after any moment can be subsequently displayed in the display window.

[0081] After obtaining the seismic images of the seismic wave field at each moment, the image names of the seismic images of the seismic wave field at each moment can also be determined, and then the image names of the seismic images of the seismic wave field at each moment and the seismic images of the seismic wave field at each moment are stored correspondingly.

[0082] Optionally, the process of determining the image name of the seismic image of the seismic wave field at each moment includes: for any moment among multiple moments, using the name prefix + automatic sequence number + name suffix as the image name of the seismic image of the seismic wave field at any moment. The name prefix is ​​set in advance by the user, and the automatic sequence number is the moment at which the seismic image of the seismic wave field in the reference time period is obtained. For example, if the seismic image of the seismic wave field at the first moment in the reference time period is obtained, the automatic sequence number is 1; for another example, if the seismic image of the seismic wave field at the 32nd moment in the reference time period is obtained, the automatic sequence number is 32. The name suffix is ​​the format of the seismic image. For example, if the format of the seismic image is PNG format, the name suffix is ​​.png; for another example, if the format of the seismic image is JPEG, the name suffix is ​​.jpeg.

[0083] In one possible implementation, before the image names of the seismic images of the seismic wave field at each moment and the seismic images of the seismic wave field at each moment are stored in correspondence, a storage location needs to be determined. The storage location is set in advance by the user, and the image names of the seismic images of the seismic wave field at each moment and the seismic images of the seismic wave field at each moment are stored in the storage location.

[0084] It should be noted that if a seismic image of the seismic wave field at any moment in other time periods is stored at the storage location, when the image name of the seismic image of the seismic wave field at any moment in the reference time period is the same as the image name of the seismic image of the seismic wave field at any moment in the other time period, the seismic image of the seismic wave field at any moment in the reference time period is stored at the storage location overwriting the seismic image of the seismic wave field at any moment in the other time period.

[0085] Exemplarily, seismic files of the seismic wave field at ten moments in a reference time period are obtained, and based on the seismic files of the seismic wave field at each moment in the reference time period, seismic images of the seismic wave field at each moment in the reference time period are obtained, namely, the seismic image at the first moment, the seismic image at the second moment, the seismic image at the third moment, the seismic image at the fourth moment, the seismic image at the fifth moment, the seismic image at the sixth moment, the seismic image at the seventh moment, the seismic image at the eighth moment, the seismic image at the ninth moment and the seismic image at the tenth moment. Among them, the image names of the seismic images at each moment are: the image name of the seismic image at the first moment is DZTX1.png, the image name of the seismic image at the second moment is DZTX2.png, the image name of the seismic image at the third moment is DZTX3.png, the image name of the seismic image at the fourth moment is DZTX4.png, the image name of the seismic image at the fifth moment is DZTX5.png, the image name of the seismic image at the sixth moment is DZTX6.png, the image name of the seismic image at the seventh moment is DZTX7.png, the image name of the seismic image at the eighth moment is DZTX8.png, the image name of the seismic image at the ninth moment is DZTX9.png, and the image name of the seismic image at the tenth moment is DZTX10.png.

[0086] In step 204, a seismic wavefield video of the seismic wavefield in a reference time period is acquired based on the seismic images of the seismic wavefield at each moment.

[0087] The seismic wave field video includes seismic images of the seismic wave field at various moments, and the seismic wave field video is used to indicate the seismic wave propagation characteristics of the seismic wave field in a reference time period.

[0088] In one possible implementation, before obtaining a seismic wavefield video of the seismic wavefield in a reference time period based on the seismic images of the seismic wavefield at each moment, the seismic images of the seismic wavefield at each moment are obtained from a storage location. The process of obtaining a seismic wavefield video of the seismic wavefield in the reference time period based on the seismic images of the seismic wavefield at each moment includes: obtaining a video frame rate and an image resolution; processing the seismic images of the seismic wavefield at each moment based on the image resolution to obtain seismic images of the seismic wavefield after processing at each moment, where the resolution of the seismic image of the seismic wavefield after processing at any moment is the image resolution; generating a seismic wave video of the seismic wavefield in the reference time period based on the video frame rate and the seismic images of the seismic wavefield after processing at each moment, where the frame rate of the seismic wavefield video of the seismic wavefield in the reference time period is the video frame rate.

[0089] The video frame rate is the frequency at which bitmap images appear continuously on the display, measured in frames. Image resolution influences the level of detail in an image. Higher resolutions contain more pixels, resulting in a clearer image and a larger storage space. Conversely, lower resolutions contain fewer pixels, resulting in a blurrier image and a smaller storage space.

[0090] The video frame rate and image resolution are pre-set by the user. The process of obtaining the video frame rate and image resolution includes: displaying an information acquisition page, which displays a video frame rate determination box and an image resolution determination box. The video frame rate determination box is used to determine the video frame rate, and the image resolution determination box is used to determine the image resolution. The user enters first information in the video frame rate determination box and second information in the image resolution determination box. The terminal device uses the first information as the video frame rate and the second information as the image resolution.

[0091] Image resolution includes horizontal resolution in the horizontal direction and vertical resolution in the vertical direction. After determining the video frame rate and image resolution, the seismic image of the seismic wave field at each moment is processed according to the image resolution to obtain the seismic image after the processing of the seismic wave field at each moment. The process includes: for any moment among multiple moments included in the reference time period, obtaining the seismic image of the seismic wave field at any moment with a first horizontal resolution and a second vertical resolution; and processing the seismic image of the seismic wave field at any moment based on the horizontal resolution, vertical resolution, first resolution, and second resolution to obtain the seismic image after the processing of the seismic wave field at any moment.

[0092] The process of processing the seismic image of the seismic wave field at any moment based on the horizontal resolution, the vertical resolution, the first resolution, and the second resolution to obtain the seismic image of the seismic wave field after processing at any moment includes the following three cases.

[0093] Case 1: Based on the fact that the first resolution and the horizontal resolution are the same and the second resolution and the vertical resolution are different, the second resolution of the seismic image of the seismic wave field at any moment in the vertical direction is adjusted to obtain the seismic image of the seismic wave field after processing at any moment.

[0094] Optionally, based on the second resolution being smaller than the vertical resolution, the vertical resolution of the seismic image of the seismic wave field at any moment is supplemented to obtain the seismic image after the seismic wave field is processed at any moment, and the vertical resolution of the seismic image after the seismic wave field is processed at any moment is the vertical resolution.

[0095] Optionally, based on the second resolution being greater than the vertical resolution, the vertical resolution of the seismic image of the seismic wave field at any moment is deleted to obtain the seismic image after the seismic wave field is processed at any moment, and the vertical resolution of the seismic image after the seismic wave field is processed at any moment is the vertical resolution.

[0096] Case 2: Based on the fact that the first resolution and the horizontal resolution are different and the second resolution and the vertical resolution are the same, the first resolution of the seismic image of the seismic wave field at any moment in the horizontal direction is adjusted to obtain the seismic image of the seismic wave field after processing at any moment.

[0097] Optionally, based on the first resolution being smaller than the horizontal resolution, the horizontal resolution of the seismic image of the seismic wave field at any moment is supplemented to obtain the seismic image after the seismic wave field is processed at any moment, and the horizontal resolution of the seismic image after the seismic wave field is processed at any moment is the horizontal resolution.

[0098] Optionally, based on the first resolution being greater than the horizontal resolution, the vertical resolution of the seismic image of the seismic wave field at any moment is deleted to obtain the seismic image after the seismic wave field is processed at any moment. The vertical resolution of the seismic image after the seismic wave field is processed at any moment is the vertical resolution.

[0099] Case 3: Based on the difference between the first resolution and the horizontal resolution, and the difference between the second resolution and the vertical resolution, the first resolution of the seismic image of the seismic wave field at any moment in the horizontal direction is adjusted, and the second resolution of the seismic image of the seismic wave field at any moment in the vertical direction is adjusted to obtain the seismic image of the seismic wave field after processing at any moment.

[0100] Among them, the process of adjusting the first resolution in the horizontal direction of the seismic image of the seismic wave field at any time has been described in the above case 2, and the process of adjusting the second resolution in the vertical direction of the seismic image of the seismic wave field at any time has been described in the above case 1, and they will not be repeated here.

[0101] In one possible implementation, after obtaining seismic images of the seismic wave field after processing at various moments, the process of generating a seismic wave field video of the seismic wave field in a reference time period based on the video frame rate and the seismic images of the seismic wave field after processing at various moments includes: determining the time interval between two adjacent frames of the seismic wave field video based on the video frame rate, and generating a seismic wave field video of the seismic wave field in the reference time period based on the time interval between the two adjacent frames of the image and the seismic images of the seismic wave field after processing at various moments. The seismic images of the seismic wave field in the seismic wave field video after processing at various moments appear in ascending order of the image names of the seismic images, or the seismic images of the seismic wave field in the seismic wave field video after processing at various moments appear in descending order of the image names of the seismic images, and this embodiment of the present application does not limit this.

[0102] In one possible implementation, based on the fact that the first resolution in the horizontal direction of the seismic image of the seismic wave field at each moment is the horizontal resolution and the second resolution in the vertical direction is the vertical resolution, there is no need to process the seismic image of the seismic wave field at each moment. A seismic wave field video of the seismic wave field in a reference time period is generated directly based on the video frame rate and the seismic image of the seismic wave field at each moment. This process is similar to the above-mentioned process of generating a seismic wave field video of the seismic wave field in a reference time period based on the video frame rate and the seismic image after processing the seismic wave field at each moment, and will not be repeated here.

[0103] It should be noted that the seismic wave field video can be in GIF (Graphics Interchange Format) format, MPEG-4 (Moving Pictures Experts Group-4), or other formats, which are not limited in the embodiments of the present application. When the seismic wave field video is in GIF format, the color components of the seismic image of the seismic wave field at each moment are counted, and the seismic wave field video is synthesized using global color mapping based on the closest color of 256-order color fitting. When the seismic wave field video is in MPEG-4 format, FFmpeg (a set of open source computer programs that can be used to record and convert digital audio and video and convert them into streams) is used to synthesize the seismic wave field video.

[0104] Optionally, after obtaining the seismic wave field video of the seismic wave field in the reference time period, the video name of the seismic wave field video can also be determined, and the seismic wave field video and the video name of the seismic wave field video are stored correspondingly. The suffix of the video name of the seismic wave field video is the format of the seismic wave field video. Optionally, if the format of the seismic wave field video is GIF format, the suffix of the video name of the seismic wave field video is .gif. If the format of the seismic wave field video is MPEG-4 format, the suffix of the video name of the seismic wave field video is .mp4. Exemplarily, according to the reference time period, the video name of the seismic wave field video is determined, and the seismic wave field video and the video name of the seismic wave field video are stored correspondingly in a storage location.

[0105] The above method determines multiple first points from multiple points included in the seismic wavefield based on amplitude information of each point included in the seismic wavefield at any moment, and then generates a seismic image of the seismic wavefield at any moment based on the relevant information of the multiple first points, thereby generating a seismic wavefield video of the seismic wavefield in a reference time period based on the seismic images of the seismic wavefield at multiple moments. When acquiring a seismic image of the seismic wavefield at any moment, this method only needs to acquire the seismic image based on the relevant information of the multiple first points of the seismic wavefield at any moment, resulting in faster and more efficient acquisition of the seismic image of the seismic wavefield at any moment, thereby improving the efficiency of acquiring seismic wavefield videos of the seismic wavefield in the reference time period and improving the efficiency of seismic data processing.

[0109] The acquisition module 501 is further configured to acquire a seismic image of the seismic wave field at any moment based on the relevant information of the plurality of first points at any moment, wherein the seismic image of the seismic wave field at any moment is used to indicate the seismic wave propagation characteristics of the seismic wave field at any moment;

[0110] The acquisition module 501 is also used to obtain a seismic wave field video of the seismic wave field in a reference time period based on the seismic images of the seismic wave field at each moment. The seismic wave field video includes the seismic images of the seismic wave field at each moment.

[0112] In one possible implementation, the relevant information includes position information, color information, and transparency information;

[0113] The acquisition module 501 is used to deduplicate multiple first points based on the color information and transparency information of the multiple first points at any moment to obtain multiple second points, where the color information of the multiple second points at any moment is different, and the transparency information of the multiple second points at any moment is different; based on the position information, color information and transparency information of the multiple second points at any moment, a seismic image of the seismic wave field at any moment is obtained.

[0114] In one possible implementation, the acquisition module 501 is used to group the multiple second points according to the position information of the multiple second points at any moment to obtain a reference number of groups, and any group includes at least one second point; based on the position information, color information and transparency information of the multiple second points included in any group in the reference number of groups at any moment, a seismic image of the seismic wave field at any moment is generated.

[0115] In one possible implementation, the acquisition module 501 is used to obtain the video frame rate and image resolution; according to the image resolution, the seismic images of the seismic wave field at each moment are processed to obtain the seismic images of the seismic wave field after processing at each moment, and the resolution of the seismic image of the seismic wave field after processing at any moment is the image resolution; according to the video frame rate and the seismic images of the seismic wave field after processing at each moment, a seismic wave field video of the seismic wave field in a reference time period is generated, and the frame rate of the seismic wave field video of the seismic wave field in the reference time period is the video frame rate.

[0116] In one possible implementation, the image resolution includes a horizontal resolution in a horizontal direction and a vertical resolution in a vertical direction;

[0117] The acquisition module 501 is used to obtain, for any moment among multiple moments included in the reference time period, a seismic image of the seismic wave field at any moment with a first horizontal resolution and a second vertical resolution; and process the seismic image of the seismic wave field at any moment based on the horizontal resolution, the vertical resolution, the first resolution, and the second resolution to obtain the seismic image of the seismic wave field after processing at any moment.

[0118] The above-mentioned device determines multiple first points from multiple points included in the seismic wavefield based on amplitude information of each point in the seismic wavefield at any moment, and then generates a seismic image of the seismic wavefield at any moment based on the relevant information of the multiple first points. Thus, based on the seismic images of the seismic wavefield at multiple moments, a seismic wavefield video of the seismic wavefield in a reference time period is generated. Because the seismic image of the seismic wavefield at any moment only needs to be acquired based on the relevant information of the multiple first points in the seismic wavefield at any moment, the seismic image of the seismic wavefield at any moment is acquired quickly and efficiently, thereby improving the efficiency of acquiring seismic wavefield videos of the seismic wavefield in the reference time period and improving the efficiency of seismic data processing.
