Problems solved by technology

[0003] In practical applications, in order to analyze or display spatial features more finely, it is necessary to obtain higher-resolution spatial data, but it is usually difficult to obtain ultra-high-precision measured spatial data
Although there are many types of interpolation methods in the prior art to improve the accuracy of spatial data, they each have different advantages and disadvantages. When the input spatial data sets are different, the performance effects of each method are quite different. Therefore, a single type The interpolation method can not meet the actual needs in terms of accuracy and adaptability

Embodiment Construction

[0036] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0037] In order to illustrate the technical solutions described in the present invention, specific examples are used below to illustrate.

[0038] A single type of interpolation method in the prior art has different advantages and disadvantages. When the input spatial data sets are different, the performance effect of a single interpolation method varies greatly. For example: the advantage of Inv...

Abstract

The invention is suitable for the technical field of spatial data processing, and provides a spatial data interpolation method and device and electronic equipment, and the method comprises the steps: obtaining first spatial data; inputting the first spatial data into a pre-trained spatial data interpolation model for interpolation processing, and outputting second spatial data; wherein the resolution ratio of the second spatial data is higher than that of the first spatial data, and the spatial data interpolation model performs deep neural network super-resolution interpolation processing, inverse distance weight interpolation processing and Kriging interpolation processing on the first spatial data. And adding the result of the deep neural network super-resolution interpolation processing and the result of the inverse distance weight interpolation processing, and then stacking the result of the inverse distance weight interpolation processing and the result of the Kriging interpolation processing to obtain second spatial data and outputting the second spatial data. The method can improve the precision of spatial data, and has good accuracy and adaptability.

Description

technical field [0001] The invention belongs to the technical field of spatial data processing, and in particular relates to a spatial data interpolation method, device and electronic equipment. Background technique [0002] Spatial data is a digital representation of topographical surface morphology, and is widely used in surveying and mapping, hydrology, meteorology, landforms, geology, soil, engineering construction, communications, military and other fields. [0003] In practical applications, in order to analyze or display spatial features more precisely, it is necessary to obtain higher-resolution spatial data, but it is usually difficult to obtain ultra-high-precision measured spatial data. Although there are many types of interpolation methods in the prior art to improve the accuracy of spatial data, they each have different advantages and disadvantages. When the input spatial data sets are different, the performance effects of each method are quite different. Theref...
