Abstract:
1. A method of defining a handoff zone for tracking a vehicle between cameras, the method comprising: receiving a first image stream from a first camera having a first field of view; receiving a second image stream from a second camera having a second field of view, the second camera being different from the first camera, and the second field of view being different from and at least partially overlapping with the first field of view; determining an overlap area that defines the overlap between the first image stream and the second image stream; determining a handoff zone within the overlap area, the handoff zone having an area that is smaller than the overlap area, the handoff zone defined by a beginning handoff border indicator and an end handoff border indicator, and wherein tracking of a vehicle is passed from the first camera to the second camera after the vehicle crosses the beginning handoff border indicator; determining a distance between the beginning handoff border indicator and the end handoff border indicator; comparing the distance to a predetermined distance threshold; determining that the distance is less than the predetermined distance threshold; generating, in response to the determination that the distance is less than the predetermined distance threshold, an alert to adjust one or more of the beginning handoff border indicator and the end handoff border indicator; and receiving and storing boundaries of the adjusted one or more of the beginning handoff border indicator and the end handoff border indicator, wherein the steps of receiving, determining, comparing, generating, receiving and storing are performed by one or more processors.
