Embodiment Construction

[0067] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0068] In order to enable those skilled in the art to have a more detailed understanding of the application scenarios and principles of the embodiments of the present invention, before introducing the embodiments of the present invention, the basic principles of the present invention are firstly introduced.

[0069] The present invention mainly utilizes the subsequently generated digital paleo-elevation model to express the topography of the paleogeographic map, and the digital paleo-elevation model is a grid raster file generated by interpolating the sedimentary facies boundaries of the lithofacies paleogeographic map as contour lines . Therefore, the present invention is mainly to generate a corresponding three-dimensional paleo...

Abstract

The invention provides a method and a device for acquiring a three-dimensional paleotopographic map. The method comprises the following steps: converting the current three-dimensional paleotopographic map into a corresponding total vector file; generating a corresponding elevation contour map according to an elevation value preset for the total vector file, wherein the elevation value is obtained according to a preset elevation range and an elevation attribute field; generating a grid grating file of the total vector file according to an elevation contour line; and acquiring a three-dimensional topographic map of the paleotopographic map according to the grid grating file. The acquisition method in the embodiment of the invention does not need relatively professional parameters, so the method has very high operability and can adapt to different occasions in practical application.

Description

technical field [0001] The invention relates to the field of graphics processing, in particular to a method and device for acquiring a three-dimensional paleotopographic map. Background technique [0002] In the process of studying paleogeomorphology, the recovery technology of paleogeomorphology topographic maps is particularly important. The restoration of paleogeomorphology can help to identify the development and distribution characteristics of reservoirs, determine the paleogeographical environment, paleontological distribution, and structural evolution characteristics. When restoring paleogeomorphology, paleogeomorphology elements play an obvious guiding role in predicting and identifying reservoirs, and different paleogeomorphology units correspond to different sedimentary systems. In general, when conducting research, once the original sedimentary structure can be clearly restored, the reservoir sand bodies can be found following the clues of paleogeomorphic units. ...
