Problems solved by technology
However, when the amount of data access is large, it is difficult to store data in the SEG-Y format to completely load the data in the accessed area. Even if the memory load can be performed, due to the large amount of data access, it is difficult to ensure real-time access.

Embodiment Construction
[0040] First, the three-dimensional data loading method provided by the embodiment of the present application is briefly described. The three-dimensional data loading method may include:
[0041] receiving a three-dimensional data loading request, wherein the three-dimensional data loading request carries a resolution corresponding to a data block, and the data block is part of the three-dimensional data;
[0042] Extract data blocks corresponding to preset resolutions from a first buffer in the memory for loading, and the data blocks in the first buffer are resident in memory;
[0043] Calculate the maximum resolution supported by the second buffer of the memory, wherein the second buffer and the first buffer constitute the entire storage area of the memory, and the maximum resolution is greater than the preset resolution;
[0044] saving the data block corresponding to the maximum resolution to the second buffer;
[0045] The loaded data block in the first buffer is repla...

The present application provides a three-dimensional data loading method and device. After receiving a three-dimensional data loading request, the three-dimensional data loading method directly extracts a data block corresponding to a preset resolution from the first buffer of the memory for loading. The display results with a preset resolution are displayed on the screen, thereby realizing the real-time loading of 3D data. Further, while loading the data block corresponding to the preset resolution, the 3D data loading method provided by the embodiment of the present application can also calculate the maximum resolution supported by the second buffer of the memory, and save the data block corresponding to the maximum resolution to the the second buffer, and load the data block in the second buffer to replace the loaded data block in the first buffer. Since the maximum resolution is greater than the preset resolution, a display result with a maximum resolution can be further displayed on the device while real-time loading is realized, so as to improve the display effect of the display result.
Description
technical field [0001] The present application relates to the technical field of data processing, and in particular, to a method and device for loading three-dimensional data. Background technique [0002] With the advancement of hardware technology, the magnitude of 3D data generation in the fields of deep earth exploration and other fields has increased rapidly. While the performance of the computers used to process data continues to improve, the explosion of three-dimensional data is still outpacing the development of computer memory. Therefore, it is very important to establish a reasonable storage format for 3D seismic data. [0003] The SEG-Y format is one of the standard tape formats proposed by SEG (Society of Exploration Geophysicists). Because of its convenient storage during data collection and simple overall storage structure, it is the format used to store three-dimensional data in the deep earth exploration industry. However, when the data access volume is l...
