Real-scene status consulting system and coordinate offset method based on GPS location and direction identification

Abstract

The invention relates to a real-scene consulting system and a coordinate offset method based on GPS location and direction identification. The system comprises a real-scene consulting electronic device based on technology of GPS location and direction identification, a communication network and an interest point database. The real-scene consulting electronic device comprises a camera, a GPS location module, a horizontal and vertical direction identification module, a display module, a data storage module, a coordinate offset converting module and a treatment control module, wherein the treatment control module is connected with the other modules. The coordinate offset converting module can offset the accurate coordinate into the offset coordinate and correct the offset coordinate into the accurate coordinate. The coordinate offset method of the invention has the advantages of improving the searching and inquiring accuracy and precision of the surrounding interest points, improving the calculation accuracy and precision of the distance between the present position and the interest point, and improving the accuracy and the precision of the real-scene function. The invention can offset the coordinate and correct the coordinate to ensure that the present position and the position of the interest point are precisely marked in the real-scene observation and the map display.

Description

technical field [0001] The invention relates to a navigation and positioning system, in particular to a real-scene consulting system based on GPS positioning and direction recognition technology and an improved method for coordinate offset. Background technique [0002] In the real scene information system based on GPS positioning and direction recognition technology, the display of real scene information or the display of a two-dimensional planar map requires the geographical location of the client to be determined through traditional GPS technology, base station positioning technology and CDMA-based GPS positioning technology. Measurement, to provide real-time consulting services for judging the GPS map coordinates and the user's actual GPS coordinates. [0003] The real scene information system based on GPS positioning and direction recognition technology can dynamically combine the real scene (point of interest) collected by it with the description information about the ...

AI Technical Summary

Problems solved by technology

Therefore, the precise coordinates received by GPS positioning cannot be accurately positioned on the offset map, resulting in relatively large deviations

In order to accurately mark on the offset map, the coordinates of all points of interest have been offset. Using GPS fixed-point coordinates to query surrounding points of interest and calculate distances will cause serious deviations. At the same time, these offset coordinates are displayed in the real scene cannot accurately match the corresponding points of interest
