1. A traffic signal violation detection system, comprising:
- a video image capture device;
an image rectifier configured to provide a rectified image by applying a rectification function to an image captured by the video image capture device;
a vehicle position predictor configured to provide a prediction, based on the rectified image, of whether a vehicle approaching an intersection will enter the intersection; and
a line generator configured to determine an intersection boundary line based on a stopping position of a plurality of vehicles at the intersection.

Abstract
A system and method for detecting a traffic signal violation. In one embodiment a system includes a video image capture device, an image rectifier, and a vehicle position predictor. The image rectifier is configured to provide a rectified image by applying a rectification function an image captured by the video image capture device. The vehicle position predictor is configured to provide a prediction, based on the rectified image, of whether a vehicle approaching an intersection will enter the intersection.

12. A method for predicting signal violations, comprising:
-
capturing, by an intersection monitoring device, a video image of a street intersection; identifying, by the intersection monitoring device, a vehicle approaching the intersection in a frame of the video image; rectifying, by the intersection monitoring device, a frame of the video image; predicting, by the intersection monitoring device, based on the rectified image, whether the vehicle approaching the intersection will enter the intersection without stopping; and determining an intersection boundary line based on the positions of a plurality of vehicles stopped at the intersection. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A non-transitory computer-readable storage medium encoded with instructions that when executed cause a processor to:
-
store a video image of a street intersection; identify a vehicle approaching the intersection in a frame of the video image; apply a rectification function to the video image to produce a rectified image; predict, based on the rectified image, whether the vehicle approaching the intersection will enter the intersection; and determine an intersection boundary line based the positions of a plurality of vehicles stopped at the intersection. - View Dependent Claims (23, 24, 25, 26, 27, 28)
