Abstract

The invention relates to an image display method and an image display system based on streetscape attribute information. The image display method comprises the following steps: step a, increasing a streetscape object labeling point in a streetscape image, establishing a streetscape space-attribute database with the streetscape image taking space longitude and latitude and image row number as labels; step b, storing a vector diagram corresponding to the streetscape target into an attribute value, in the streetscape space-attribute database, of the vector diagram, associating the vector diagram of the streetscape target with the space longitude and latitude and the image row number of a labeling point pixel of the streetscape target; step c, selecting the vector diagram in the streetscape space-attribute database, and drawing the vector diagram of the streetscape object on a corresponding streetscape object labeling point position. The image display method is beneficial to improving the navigation ability of the streetscape and improving the experience effect.

Description

technical field

[0001] The invention belongs to the technical field of electronic maps, in particular to a graphic display method and system based on street view attribute information. Background technique

[0002] The wide application of street view maps has become the main content of Internet maps. However, the current street view map can only provide functions such as browsing and viewing, and it is difficult to carry out query search and spatial positioning based on image content. The reason is that there is no effective support from the street view database to establish correspondence between street view image elements and their attributes. For example, in the Tencent Street View map, at present, only the attribute information (name, distance, etc.) based on the "location" can be displayed in text form. For the "pixel entities" on the Street View image, such as streets, buildings, etc., there is no corresponding attribute available. Query, display. Contents of the in...
