Abstract

The invention provides an automobile parking point static drift detection method and system. The method comprises the following steps: when an automobile is in a parking state, obtaining a plurality of automobile parking point information according to time sequence, and adding the parking point information into a parking point list; according to the parking point information in the parking point list, determining a logic parking center point and a logic parking range of the automobile; re-obtaining new parking point information of the automobile; according to position coordinates and vehicle speed of the new parking point of the automobile, judging whether the new automobile parking point is within the logic parking range and the vehicle speed is smaller or equal to a preset driving judgment speed; if so, connecting the new automobile parking point with the last two automobile parking points in the parking point list in the obtaining time to form a parking point included angle; and judging whether the parking point included angle is larger than or equal to a preset drift judgment angle, and if so, determining the new automobile parking point as a static drift point. The technical scheme can detect whether the positioning information has automobile parking point drift cases.

Description

technical field [0001] The invention relates to the technical field of communication, and more specifically, to a static drift detection method and system of a parking spot of an automobile. Background technique [0002] Automotive GPS (Global Positioning System, Global Positioning System) positioning technology is widely used in the fields of vehicle positioning, navigation, and anti-theft. In order to realize the positioning of the car, it is often necessary to install a GPS vehicle antenna in the car, and transmit a communication signal to the GPS satellite through the vehicle antenna, so that the GPS satellite can determine the position of the car and other data according to the communication signal, and then the GPS satellite will include the position of the car The GPS positioning signal of the data is sent to the ground user equipment (such as a GPS receiver or server), and the ground user equipment analyzes and calculates the GPS positioning signal to realize the pos...
