RELIABILITY IN DETECTING RAIL CROSSING EVENTS
First Claim
1. A method for monitoring objects, the method comprising:
- receiving a plurality of images of an area;
identifying an object in the area from the plurality of images;
identifying a plurality of points in a region within the area from a first image in the plurality of images, wherein the plurality of points has a fixed relationship with each other and the region;
monitoring the object in the area to determine whether the object has entered the region; and
responsive to identifying an absence of a number of the plurality of points in a second image in the plurality of images, determining, using a processor unit, that the object has not entered the region.

Abstract
A method, data processing system, apparatus, and computer program product for monitoring objects. A plurality of images of an area is received. An object in the area is identified from the plurality of images. A plurality of points in a region within the area is identified from a first image in the plurality of images. The plurality of points has a fixed relationship with each other and the region. The object in the area is monitored to determine whether the object has entered the region. A determination that the object has not entered the region is made in response to identifying an absence of a number of the plurality of points in a second image in the plurality of images.

11. An apparatus for monitoring objects, the apparatus comprising:
-
an object monitoring system operably connected to a camera, the object monitoring system configured to identify an object in an area from a plurality of images of the area generated by the camera and monitor the object in the area to determine whether the object has entered a region within the area, wherein the region includes a portion of a set of train tracks; and a train detection system comprising a processing unit and operably connected to the object monitoring system, the train detection system configured to identify a plurality of points in a region within the area from a first image in the plurality of images and determine that a train has entered the region rather than the object in response to identifying an absence of a number of the plurality of points in a second image in the plurality of images, wherein the plurality of points has a fixed relationship with each other and the region. - View Dependent Claims (12, 13, 14)

20. A data processing system for monitoring objects, the data processing system comprising:
-
a bus system; a storage device connected to the bus system, wherein the storage device includes program code; and a processor unit connected to the bus system, wherein the processor unit is configured to execute the program code to receive a plurality of images of an area, identify an object in the area from the plurality of images, identify a plurality of points in a region within the area from a first image in the plurality of images, wherein the plurality of points has a fixed relationship with each other and the region, monitor the object in the area to determine whether the object has entered the region, and determine that the object has not entered the region in response to identifying an absence of a number of the plurality of points in a second image in the plurality of images. - View Dependent Claims (21, 22, 23, 24)
