Embodiment Construction

[0038] In order to make the purpose, technical solution and advantages of the present application clearer, the following will give a clear and complete description of the present application in conjunction with specific embodiments of the present application. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0039] In the existing technology, the geographic data can be converted into a three-dimensional visualization form by visualizing the three-dimensional map through the Web Graphics Library (WebGL). The map makes it easier for users to understand data rules and trends.

[0040] In the WebGL three-dimensional map, if you want to observe the details of the target, you need to manually adjust...

Abstract

The invention discloses a method and equipment for determining an observation position based on a three-dimensional map, belongs to the field of data processing, is applied to a WebGL three-dimensional map, and comprises the following steps: obtaining longitude coordinates and latitude coordinates of an observed object at the current moment; determining the height of the observation position corresponding to the observed object in the vertical direction and the observation angle for observing the observed object based on triggering of a user on the related observed object in the WebGL three-dimensional map; determining the horizontal distance between the observed object and the observation position according to the height of the observation position in the vertical direction and the observation angle for observing the observed object; determining a horizontal deflection angle of the observation position relative to the observed object according to the orientation of the observation position relative to the observed object; and determining the latitude coordinate and the longitude coordinate of the observation position according to the latitude coordinate, the longitude coordinate, the horizontal distance and the horizontal deflection angle of the observed object.

Description

technical field [0001] The present application relates to the field of data processing, and in particular to a method and device for determining an observation position based on a three-dimensional map. Background technique [0002] By visualizing the three-dimensional map through the Web Graphics Library (WebGL), geographic data can be converted into a three-dimensional visualization form. By visually displaying data with regional characteristics or data analysis results on the three-dimensional map, users can It is easier to understand data patterns and trends. [0003] In the WebGL 3D map, if you want to observe the details of the target, you need to manually adjust the observation position in the existing method, including adjusting the longitude, latitude, height, and observation angle of the observation position, and then refresh the 3D map page to view the observation effect. If the effect is not Well, it is necessary to repeatedly adjust the observation position. ...
