Abstract
A multi-object tracking method includes generating multi-dimensional physical characterization data associated with a plurality of objects; simplifying the multi-dimensional physical characterization data to reduce at least one dimension thereof, thereby resulting in a simplified data set; and tracking by comparing a current simplified data set and a stored data set in a database. If the current simplified data set conforms to the stored data set in the database, a proper operation is correspondingly performed; otherwise the current simplified data set is defined as a new event and stored in the database.
Claims20
A multi-object tracking method, comprising:
- (a) generating, by a processor, multi-dimensional physical characterization data associated with a plurality of objects, the multi-dimensional physical characterization data being generated according to radio-frequency (RF) transmitting signals transmitted to the objects and reflected RF receiving signals reflected from the objects;
- (b) simplifying, by the processor, the multi-dimensional physical characterization data to reduce at least one dimension thereof, thereby resulting in a simplified data set;
- and
- (c) tracking, by the processor, the plurality of objects by comparing a current simplified data set and a stored data set in a database;
- wherein in response to a comparison result that the current simplified data set is equal to the stored data set in the database, a predetermined operation is correspondingly performed;
- in response to a comparison result that the current simplified data set is not equal to the stored data set in the database, the current simplified data set is defined as a new event and stored in the database.
A multi-object tracking system, comprising:
- a processor that generates multi-dimensional physical characterization data associated with a plurality of objects according to radio-frequency (RF) transmitting signals transmitted to the objects and reflected RF receiving signals reflected from the objects, and simplifies the multi-dimensional physical characterization data to reduce at least one dimension thereof, thereby resulting in a simplified data set;
- and
- a database that stores a plurality of data sets;
- wherein the processor tracks the plurality of objects by comparing a current simplified data set and a stored data set in the database;
- in response to a comparison result that the current simplified data set is equal to the stored data set in the database, a predetermined operation is correspondingly performed;
- in response to a comparison result that the current simplified data set is not equal to the stored data set in the database, the current simplified data set is defined as a new event and stored in the database.
