Virtual Grid Dictionary Based Target Heading Class Intention Recognition Method and Device

摘要

The application relates to a virtual grid dictionary based target heading class intention recognition method and a virtual grid dictionary based target heading class intention recognition device. The method includes the steps of: acquiring the longitude and latitude data of a task space, and transforming the task space into a longitude-latitude grid according to the longitude and latitude data; setting up a first virtual grid dictionary corresponding to a task target according to the longitude and latitude of the task target corresponding to a flight target and the longitude-latitude grid; determining whether the flight target is switched to a straight flight mode according to the longitudes and latitudes and current longitudes and latitudes of historical flight paths of the flight target; querying the task target in the flight path of the flight target according to a sensitive area corresponding to the preset task target and the first virtual grid dictionary when the flight target is in the straight flight mode, where the task target is queried according to a situation that whether the flight target is in the range of the sensitive area; and determining the task type of the flight target according to the type of the task target in an expected flight path. The method can improve the efficiency of intention recognition.
