SHORT-TIME STOPPING DETECTION FROM RED LIGHT CAMERA VIDEOS
First Claim
1. A method to detect a vehicle running a stop signal positioned at an intersection, the method comprising:
- acquiring a sequence of frames from at least one video camera monitoring an intersection being signaled by the stop signal;
defining a first region of interest (ROI) including a road region located before the intersection on the image plane;
searching the first ROI for a candidate violating vehicle;
in response to detecting the candidate violating vehicle, tracking at least one trajectory of the detected candidate violating vehicle across a number of frames;
classifying the candidate violating vehicle as belonging to one of a violating vehicle and a non-violating vehicle based on the at least one trajectory.

Abstract
A method for detecting a vehicle running a stop signal positioned at an intersection includes acquiring a sequence of frames from at least one video camera monitoring an intersection being signaled by the stop signal. The method includes defining a first region of interest (ROI) including a road region located before the intersection on the image plane. The method includes searching the first ROI for a candidate violating vehicle. In response to detecting the candidate violating vehicle, the method includes tracking at least one trajectory of the detected candidate violating vehicle across a number of frames. The method includes classifying the candidate violating vehicle as belonging to one of a violating vehicle and a non-violating vehicle based on the at least one trajectory.

11. A system for detecting a vehicle running a stop signal positioned at an intersection, the system comprising a traffic regulation enforcement device including a memory and a processor in communication with the processor configured to:
-
acquire a sequence of frames from at least one video camera monitoring an intersection being signaled by the stop; define a first region of interest (ROI) including a road region located before the intersection on the image plane; search the first ROI for a candidate violating vehicle; in response to detecting the candidate violating vehicle, track at least one trajectory of the detected candidate violating vehicle; classify the candidate violating vehicle as belonging to one of a violating vehicle and a non-violating vehicle based on the at least one trajectory. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
