Problems solved by technology

[0003] However, in some cases, for example, the operator has not had time to survey and map after the new road is laid, or the position information collected by the operator on the road is wrong, or the operator cannot reach remote areas for survey and mapping at all, etc., may cause serious problems. As a result, the existing road network information is no longer accurate, which leads to the reduction of the reliability of road network information, and further reduces the reliability of searching based on road network information

Abstract

The invention discloses a satellite image processing method, which comprises the following steps of: obtaining a first digital image through a map drawing application program, and describing a set first area by the first digital image; obtaining a second digital image via the drawing application, the second digital image depicting a second region of the setting, the second region and the first region at least partially overlapping each other; determining a displacement factor between the first digital image and the second digital image; generating a third digital image by cropping the second digital image based on the displacement factor; adjusting the aspect ratio of the third digital image based on the aspect ratio of the first digital image such that the aspect ratio of the third digital image is substantially the same as the aspect ratio of the first digital image; adjusting the size of the third digital image to have substantially the same size as the size of the first digital image; and generating a stereoscopic map image which comprises settings of a first eye image based on the first digital image and which comprises a second eye image based on the third digital image.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a satellite image processing method. Background technique [0002] With the development of communication technology, the terminal integrates more and more functions, so that the system function list of the terminal includes more and more corresponding application programs. Some applications will involve some location services (Location Based Service, LBS), also known as positioning services, for example, Baidu Maps, etc. In LBS, the server stores a large amount of road network information, which can also be called road network data, to provide the client with search results based on road network information. Among them, the road network information may include road name, location information (namely longitude and latitude, etc.) and other aspects of information. Generally speaking, the existing road network information is obtained by the operator on the actual road sur...
