1. A system comprising:
- a monitoring assembly deployed to monitor an area, wherein the monitoring assembly includes;
a plurality of cameras including at least two cameras sensitive to radiation of distinct wavelength ranges, wherein the fields of view of the at least two cameras are substantially co-registered at the area; and
a computer system configured to monitor the area by performing a method including;
operating the plurality of cameras to substantially concurrently acquire image data of the area;
identifying a set of relevant objects in the area using the image data acquired by the plurality of cameras;
updating tracking information for each object in the set of relevant objects; and
evaluating an alert condition in response to the tracking information for each of the set of relevant objects.

Abstract
An assembly for monitoring an area is provided. The assembly can include two or more cameras sensitive to radiation of distinct wavelength ranges. The fields of view of the cameras can be substantially co-registered at the area to be monitored. The assembly can include a computer system which can process the image data to monitor the area. The computer system can be configured to identify relevant objects present in the area, update tracking information for the relevant objects, and evaluate whether an alert condition is present using the tracking information.

11. A method comprising:
-
acquiring multispectral image data of an area on a computer system of a monitoring assembly including a plurality of cameras including at least two cameras sensitive to radiation of distinct wavelengths; the computer system identifying a set of relevant objects in the area using the multispectral image data; the computer system updating tracking information for each object in the set of relevant objects; the computer system evaluating an alert condition in response to the tracking information for each of the set of relevant objects; and the computer system performing an action response to evaluating a presence of an alert condition. - View Dependent Claims (12, 13, 14, 15, 16)

17. An at-grade railroad crossing comprising:
-
a road intersecting with railroad tracks; and a monitoring assembly deployed to monitor the railroad crossing, wherein the monitoring assembly includes; a first camera sensitive to near infrared and visible radiation; a second camera sensitive to infrared radiation, wherein the fields of view of the first and second cameras are substantially co-registered at the intersection of the road and the railroad tracks; and a computer system configured to monitor the railroad crossing by performing a method including; identifying a set of relevant objects in the area using image data substantially concurrently acquired by the first and second cameras; updating location and tracking information for each object in the set of relevant objects; and evaluating an alert condition using the location and tracking information for each of the set of relevant objects and an amount of time until a train next uses the railroad crossing. - View Dependent Claims (18, 19, 20)
