Abstract

The invention provides a calibrating method and system for navigation display data. The method comprises the following steps: modifying received navigation source data, and primarily screening the modified navigation source data to obtain basic navigation data; performing distance compensation and offset calibration processing on the basic navigation data to obtain secondarily processed data; performing sparse processing on the secondarily processed data according to a historical data sparse algorithm to obtain the navigation display data. The system comprises a basic navigation data acquisition module, a secondarily processed data acquisition module and a navigation display data acquisition module. According to the method and the system, the display accuracy of the navigation data on display equipment is effectively improved; the defects that data cannot be displayed, a display position is wrong or the like are avoided; the display reliability of the navigation data is ensured; therefore, the safety of a running vehicle which applies the navigation data and the scheduling accuracy are ensured.

Description

technical field [0001] The invention relates to the technical field of navigation calibration, in particular to a calibration method and system for navigation display data. Background technique [0002] With the development of society, people have higher and higher requirements on the user experience effect of applications, especially in the field of command and dispatch. However, currently existing technologies all focus on the accuracy and real-time performance of navigation data, and there is no good way to improve user experience and user perception. After various analysis, the existing technologies mainly focus on the quality of the navigation device itself, and do not pay attention to the experience effect of the end user. [0003] At present, the data reported by navigation terminals on the market has the following problems: data offset, data incoherence, a large number of repeated data, and inaccurate data compensation for detours and inflection points. For such dat...
