The invention discloses an intersection navigation induction point mining method, device and equipment and a storage medium, and relates to the field of intelligent transportation. According to the specific implementation scheme, the method comprises the steps of collecting a plurality of historical track segments which pass through a specified intersection and have the same driving direction; digging a navigation induction point passing through a specified intersection in the driving direction from each historical track segment; and analyzing the navigation induction point of the specified intersection in the driving direction based on the navigation induction point passing through the specified intersection in the driving direction corresponding to each historical track segment in the plurality of historical track segments. According to the method, the navigation induction points of the intersection can be accurately mined based on the historical track segments, and the accuracy of the mined navigation induction points of the intersection can be effectively improved. And moreover, the mining process of the navigation induction points of the intersection can be effectively simplified, the manpower and the mining cost can be saved, the mining time of the navigation induction points of the intersection can be effectively shortened, and the mining efficiency of the navigation induction points of the intersection is improved.
Description
technical field [0001] The present application relates to computer technology, in particular to the field of intelligent transportation, and in particular to a method, device, equipment and storage medium for excavating navigation guidance points at intersections. Background technique [0002] When the existing map application provides navigation guidance prompts for the user, it usually sends a prompt message such as "turn left" or "turn right" to the user when the user reaches the critical point of the intersection. However, in fact, when the user reaches the critical point of the intersection, if the speed of the vehicle is fast, the lane cannot be changed in time, which will cause the user to fail to complete the turn in time. [0003] Theoretically, a navigation induction point should be excavated at a position before the critical point of the intersection. When the user reaches the navigation induction point, an induction prompt will be sent to the user to ensure that ...
