Abstract

The present application discloses a method and device for determining the straight relationship between roads, and a hybrid navigation system. The method includes: obtaining an entry road and an exit road associated with the entry road, and for each exit associated with the entry road road, select at least four marking points on the entering road and the exiting road, determine the angle formed by any adjacent three marking points in the at least four marking points, and determine the exit road according to the determined Corresponding to the angles of each included angle, it is determined whether the entry road and each exit road belong to the straight relationship. Since at least four marking points are selected on the exit road, the line between the marking points is closer to the actual degree of curvature of the road, therefore, by implementing the present invention, the calculation of any adjacent three marking points in the at least four marking points constitutes In this way, the angle between roads can be more truly reflected, and the accuracy of determining the straight relationship between roads can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a method and device for determining a straight relationship between roads, and a hybrid navigation system. Background technique [0002] With the continuous development of network technology, service providers provide users with more and more diverse services, such as providing users with map voice navigation services. [0003] At present, in order to provide users with more accurate map voice navigation services and to reduce the operating pressure of navigation equipment, it is usually necessary to determine whether two roads are in a straight relationship through calculation in advance. Whether the roads belong to the straight relationship is provided to the navigation device as an important reference information for the navigation device to perform voice prompts. For example, when the user drives from one road to another, if it is determined in advance by calc...
