Problems solved by technology

The time complexity of the above-mentioned ray method is linearly related to the number of fence points. When the number of geographical fence points (or, the number of edges) is too large, the efficiency of the algorithm is low

Abstract

The present invention provides a method and a device for determining a relationship between a point and a fence and an electronic device, and relates to the technical field of data processing. The method includes the following steps: determining a target grid where a target point is located; determining a fence containing the target grid in an index grid as a target fence, wherein a fence object of the target fence includes a local fence which is an intersection area of a boundary grid of the target fence and the target fence; judging whether the target grid is included in the boundary grid ofthe target fence; and if the target grid is included in the boundary grid of the target fence, according to the positional relationship between the target point and the local fence, determining the positional relationship between the target point and the target fence. The method can improve the determination efficiency of the positional relationship between the point and the fence, and can also identify more accurately the relationship between the point and the fence.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a method, device and electronic equipment for determining the relationship between a point and a fence. Background technique [0002] An online car-hailing platform is an online platform that connects passengers and car-hailing drivers. When a passenger sends a ride order to the online car-hailing platform that includes the ride demand, the online car-hailing platform will assign the ride order to the corresponding online car-hailing driver, and the online car-hailing driver can serve the passenger according to the ride order. Provide services. [0003] When refining the operation of the online car-hailing platform, it is necessary to quickly identify the city and region where the driver or passenger is currently located, and adopt different strategies in specific cities and regions, such as mobilization strategies. The above cities and regions can be repr...
