Abstract
Various techniques are provided for counting and/or tracking objects within a field of view of an imaging system, while excluding certain objects from the results. A monitoring system may count or track people identified in captured images while utilizing an employee identification system including a wireless signal receiver to identify and remove the employees from the result. The system includes algorithms for separating employee counts from customer counts, thereby offering enhanced tracking analytics.
Claims20
A system, comprising:
- a first image sensor operable to capture a stream of images of a first field of view;
- a wireless signal sensor operable to detect wireless signals emitted from at least one wireless device within an area comprising at least the first field of view;
- and
- a processing system operable to:
- process the stream of images and detect a plurality of objects within the first field of view;
- generate a plurality of object tracks, each object track representative of a movement of a detected object within the first field of view;
- predict, for at least one of the plurality of object tracks, a wireless signal characteristic of a predicted wireless device following the at least one of the object tracks;
- process the detected wireless signals, including tracking the wireless signal characteristic;
- and
- match one of the plurality of object tracks with a detected wireless device based on a fit between the predicted wireless signal characteristic and the tracked wireless signal characteristic.
7 more elements
A method comprising:
- capturing images, using a first image sensor, of a first field of view;
- receiving, using a wireless signal sensor, wireless signals emitted from one or more wireless devices within an area comprising at least the first field of view;
- and
- processing the captured images and wireless signals to identify and classify objects in the first field of view, the processing comprising:
- detecting in the captured images an object within the first field of view;
- generating an object track representative of a movement of the object within the first field of view;
- predicting a wireless signal characteristic of a predicted wireless device following the object track;
- tracking the wireless signal characteristic in the received wireless signals;
- and
- matching the object track with a detected wireless device based on a fit between the predicted wireless signal characteristic and the tracked wireless signal characteristic.
