Abstract

The invention relates to a multi-scale display method for space environment data, a model building method and a device, and belongs to the technical field of space environment data processing. The present invention first obtains the spatial environment data, and determines the K adjacent point information of each point in the spatial environment data; Calculate the comprehensive eigenvalue of each point by the degree of surface change and directional derivative of the point; judge whether the comprehensive eigenvalue of each point is greater than the first set threshold, and keep the points greater than the first set threshold as feature points, and finally according to the retained feature points Perform multi-scale model building. The multi-scale model of the present invention not only considers the geometric characteristics of the space environment data, but also considers the attribute characteristics of the space environment data, and the built model can accurately express the space environment data.

Description

technical field

[0001] The invention relates to a multi-scale display method for space environment data, a model building method and a device, and belongs to the technical field of space environment data processing. Background technique

[0002] In order to study the effect of space environment, people use various types of sensors to obtain a large amount of space environment data. In addition to using these data to establish various space environment models, they also use various two-dimensional charts and three-dimensional visualization methods to express these data. It can obtain the changing laws and trends of the space environment, especially the 3D visualization technology can not only provide a more realistic expression of the space environment, but also interact with the research objects and observe the space environment from multiple angles.

[0003] With the increase of various space detection methods, the space environment data has shown an exponential growth. In ...
