Abstract

Tracking vehicles is disclosed. Initially, two or more first images from a first camera having a first field of view are received. Next, a first static characteristic and a first dynamic characteristic of a first vehicle are determined based on the two or more first images. Next, two or more second images from a second camera having a second field of view are received. A second static characteristic and a second dynamic characteristic of the first vehicle are determined based on the two or more second images. The first characteristics and the second characteristics are compared to determine that the second characteristics are approximately equal to the first characteristics of the first vehicle. Finally, it is indicated that the first vehicle is present in the second field of view of the second camera.

Dependent claims

A method of tracking vehicles, the method comprising:

receiving two or more first images from a first camera having a first field of view, the two or more first images showing a first vehicle;
determining, based on at least one of the two or more first images, a first static characteristic of the first vehicle;
determining, based on at least two of the two or more first images, a first dynamic characteristic of the first vehicle;
receiving two or more second images from a second camera having a second field of view, the two or more second images showing the first vehicle, the second camera being different from the first camera, and the second field of view being different from the first field of view;
determining, based on at least one of the two or more second images, a second static characteristic of the first vehicle;
determining, based on at least two of the two or more second images, a second dynamic characteristic of the first vehicle;
comparing the second static characteristic of the first vehicle to the first static characteristic of the first vehicle;
determining, in response to the comparison of the second static characteristic of the first vehicle and the first static characteristic of the first vehicle, that the second static characteristic of the first vehicle is approximately equal to the first static characteristic of the first vehicle;
comparing the second dynamic characteristic of the first vehicle to the first dynamic characteristic of the first vehicle;
determining, in response to the comparison of the second dynamic characteristic of the first vehicle and the first dynamic characteristic of the first vehicle, that the second dynamic characteristic of the first vehicle is approximately equal to the first dynamic characteristic of the first vehicle;
determining, in response to the approximate equivalence between the second static characteristic of the first vehicle and the first static characteristic of the first vehicle and the approximate equivalence between the second dynamic characteristic of the first vehicle and the first dynamic characteristic of the first vehicle, that the first vehicle is present in the second field of view of the second camera;
and
indicating, in response to the determination that the first vehicle is present in the second field of view of the second camera, that the first vehicle is present in the second field of view of the second camera,
wherein the steps of receiving, determining, comparing and indicating are performed by one or more processors.
