Abstract

The invention provides a position positioning retrieval device and a position positioning retrieval method. The device comprises a spatial retrieval information module for acquiring spatial retrieval information of a current position in a three-dimensional space, an image acquisition module for acquiring focusing range information in a current focusing range and intercepting a scene in the focusing range to form a selected image according to the spatial retrieval information, a map data query module for searching map data accordant with the spatial retrieval information and the focusing range information according to the spatial retrieval information and the focusing range information, and a description information projection module for projecting the map data obtained by the map data query module onto the selected image. Due to the application of the technology provided by the invention, expensive unit modules are not adopted any longer, thus the cost of the retrieval device is reduced and further the retrieval device is favorably popularized; and at the same time, display granularities of the position information and the position description information are regulated according to the focusing range, so that clear and accurate position information and position description information of the surrounding scenes are timely and conveniently provided to users and the experiences of the users are enhanced.

Description

technical field

[0001] The present invention relates to position positioning technology, in particular to a position positioning retrieval device and method. Background technique

[0002] At present, with the expansion of people's travel range, the need for location positioning technology has become more and more. It is very cumbersome and difficult for users to know the destination in a new environment without knowing the destination.

[0003] In the prior art, the global positioning system (GPS, Global Positioning System) is usually used for positioning services. Due to the limitation of the display capability of GPS equipment, users need to accurately define multiple sets of keywords, query the database module, and manually select to obtain Possible alternative information. However, due to the limitation of input and user retrieval ability, it becomes a very time-consuming and skillful work to comprehensively search for surrounding targets. Moreover, a considerable numb...
