Abstract

The invention provides a real-time trajectory correction method and device for an intersection. The present invention matches the data information of track points collected by GPS with the map data in real time, calculates the range value of the direction of the front of the vehicle according to the historical track points for the GPS track points that are not on the road, and compares it with the direction of the sensor module, according to the matching module Match the GPS track points that are not on the road to the road, and update the new GPS track point data to achieve the purpose of real-time track correction at the intersection. The present invention can also detect the speed data information of the mobile terminal through the sensor module. If the mobile terminal does not turn to change the road at the corresponding intersection position, the speed will not change much, and the probability of matching the original road will increase greatly. The mobile terminal will move when changing the road and turning If the end will slow down, the map matching module will match the GPS track point to the road that is about to turn, so as to ensure that the GPS track point is displayed on the correct road.

Description

technical field [0001] The invention relates to the field of position map positioning, in particular to a real-time trajectory correction method and device for an intersection. Background technique [0002] On urban roads, real-time, accurate, and reliable trajectory prediction for mobile terminals has extremely high application value. It can not only provide accurate location-based services, but also help passing mobile terminals predict the traffic conditions ahead. With the rapid development of the Internet of Things, there are more and more GIS-based applications with various functions. Real-time monitoring and positioning are one of them. However, due to weather conditions, high-rise buildings, etc., the GPS signal is weakened. GPS data error. In addition, the urban road network structure is complex and there are many intersections. Therefore, it is relatively difficult to display the real-time trajectory correctly on the map. [0003] Such as figure 1 As shown, the ...
